means pick from the `crypto' (context) and otherwise use that
type. this is not a large change in practice and allows callers
to specify the exact checksum algorithm to use
2001-03-13 Assar Westerlund <assar@sics.se>
* lib/krb5/get_cred.c (get_cred_kdc): add support for falling back
to KRB5_KU_AP_REQ_AUTH when KRB5_KU_TGS_REQ_AUTH gives `bad

DDEESSCCRRIIPPTTIIOONN
kkttuuttiill is a program for managing keytabs. _c_o_m_m_a_n_d can be one of the fol-
lowing:
add [--pp _p_r_i_n_c_i_p_a_l] [----pprriinncciippaall==_p_r_i_n_c_i_p_a_l] [--VV _k_v_n_o] [----kkvvnnoo==_k_v_n_o] [--ee

[--rr] [----rraannddoomm] [--ss] [----nnoo--ssaalltt]
Adds a key to the keytab. Options that are not specified will be
prompted for.
change [--rr _r_e_a_l_m] [----rreeaallmm==_r_e_a_l_m] [----aa _h_o_s_t] [----aaddmmiinn--sseerrvveerr==_h_o_s_t] [----ss
_p_o_r_t] [----sseerrvveerr--ppoorrtt==_p_o_r_t]
Update one or several keys to new versions. By default, use the
admin server for the realm of an keytab entry. Otherwise it will
use the values specified by the options.
If no principals are given, all the ones in the keytab are updat-
ed.
copy _k_e_y_t_a_b_-_s_r_c _k_e_y_t_a_b_-_d_e_s_t
Copies all the entries from _k_e_y_t_a_b_-_s_r_c to _k_e_y_t_a_b_-_d_e_s_t.
get [--pp _a_d_m_i_n _p_r_i_n_c_i_p_a_l] [----pprriinncciippaall==_a_d_m_i_n _p_r_i_n_c_i_p_a_l] [--ee _e_n_c_t_y_p_e |

[----aaddmmiinn-- Get a key for pprriinncciippaall and store it in a keytab.
list [----kkeeyyss] [----ttiimmeessttaammpp]
List the keys stored in the keytab.
remove [--pp _p_r_i_n_c_i_p_a_l] [----pprriinncciippaall==_p_r_i_n_c_i_p_a_l] [--VV --kkvvnnoo] [----kkvvnnoo==_k_v_n_o]
[--ee --eennccttyyppee] [----eennccttyyppee==_e_n_c_t_y_p_e]
Removes the specified key or keys. Not specifying a _k_v_n_o removes
keys with any version number. Not specifying a _e_n_c_t_y_p_e removes
keys of any type.
purge [----aaggee==_a_g_e]
Removes all old entries (for which there is a newer version) that
are older than _a_g_e (default one week).
srvconvert
srv2keytab [--ss _s_r_v_t_a_b] [----ssrrvvttaabb==_s_r_v_t_a_b]
Converts the version 4 srvtab in _s_r_v_t_a_b to a version 5 keytab and
stores it in _k_e_y_t_a_b. Identical to:
ktutil copy krb4:_s_r_v_t_a_b _k_e_y_t_a_b
srvcreate
key2srvtab [--ss _s_r_v_t_a_b] [----ssrrvvttaabb==_s_r_v_t_a_b]
Converts the version 5 keytab in _k_e_y_t_a_b to a version 4 srvtab and
stores it in _s_r_v_t_a_b. Identical to:
ktutil copy _k_e_y_t_a_b krb4:_s_r_v_t_a_b

This is a set of patches and files to get a DFS ticket from a k5 ticket.
This code comes from Doug Engert, Argonne Nat. Lab (See dce/README.original
for more info)
The files in dce are;
testpag: for testing if this is at all possible.
k5dfspag: included in libkrb5
k5dcecon: Creates (or searches for) the actual DFSPAG ticketfile.
dpagaix: An AIX syscall stub.
README.original: Original README file from Doug Engert
Certain applications (rshd/telnetd) have been patched to call the
functions in k5dfspag when the situation is right. They are ifdef
with DCE. The patches are also originally from Doug but they
where against MIT krb5 code and have been merged into heimdal by me.
I will try to fix ftpd soon...
There is also an ifdefs for DCE && AIX that can be used to make AIX
use DCE for getting group/passwd entries. This is needed if one is running
with a bare bones passwd/group file and AUTHSTATE set to DCE (This will be
more or less clear to people doing this...) I have forced this on for now.
k5dfspag.c is in lib/krb5
k5dfspag.c is dependent on DCE only.
It is also POSIX systems only. There are defines for the location of
k5dcecon and dpagaix that needs a correct configure setting.
k5dcecon needs no special things for the compile except whatever is needed
on the target system to compile dce programs.
(On aix the dce compile flags are: -D_THREAD_SAFE -D_AIX32_THREADS=1 -D_AIX41 -D_AES_SOURCE or one can use xlc_r4 if it is version 3.6.4 or later)
k5dcecon wants the following libs (on aix 4.3):
-ldce (and setenv from somewhere)
dpagaix is only needed on AIX (see k5dfspag.c).
dpagaix needs dfspag.exp and is linked with
ld -edpagaix -o dpagaix dpagaix.o dfspag.exp
Hope to get this into heimdal soon :-) although I know that you will have to
change some things to get it cleanly into configure. Since I don't know the
structure of the code (heimdal), nor enough of configure, good enough I
just won't try it myself.
One more thing, to get this to work one has to put fcache_version = x in
krb5.conf where x = whatever the DCE implementation understands, (usually
1 or 2).
Thanks for adding that...

PS
I have now added patches for configure.in and some Makefile.am's to get this
all cleanly (I hope) into heimdal.

KERBEROS and DCE INTEROPERABILITY ROUTINES
WHAT'S NEW
When k5dcecon was examining the ticket caches looking to
update one with a newer TGT, it might update the wrong
one for the correct user. This problem was reported by PNNL,
and is now fixed.
Any Kerberized application can now use a forwarded TGT to establish a
DCE context, or can use a previously established DCE context. This is
both a functional improvement and a performance improvement.
BACKGROUND
The MIT Kerberos 5 Release 1.x and DCE 1.1 can interoperate in a
number of ways. This is possible because:
o DCE used Kerberos 5 internally. Based on the MIT code as of beta 4
or so, with additional changes.
o The DCE security server can act as a K5 KDC, as defined in RFC 1510
and responds on port 88.
o On the clients, DCE and Kerberos use the same format for the ticket
cache, and then can share it. The KRB5CCNAME environment variable points
at the cache.
o On the clients, DCE and Kerberos use the same format for the srvtab
file. DCE refers to is a /krb5/v5srvtab and Kerberos as
/etc/krb5.keytab. They can be symlinked.
o MIT has added many options to the krb5.conf configuration file
which allows newer features of Release 1.0 to be turned off to match
the earlier version of Kerberos upon which DCE is based.
o DCE will accept a externally obtained Kerberos TGT in place of a
password when establishing a DCE context.
There are some areas where they differ, including the following:
o Administration of the database and the keytab files is done by the
DCE routines, rather the the Kerberos kadmin.
o User password changes must be done using the DCE commands. Kpasswd
does not work. (But there are mods to Kerberos to use the v5passwd
with DCE.
o DCE goes beyond authentication only, and provides authorization via
the PAC, and the dce-ptgt tickets stored in the cache. Thus a
Kerberos KDC can not act as a DCE security server.
o A DCE cell and Kerberos realm can cross-realm authenticate, but
there can be no intermediate realms. (There are other problems
in this area as well. But directly connected realms/cells do work.)
o You can't link a module with the DCE library and the Kerberos
library. They have conflicting routines, static data and structures.
One of the main features of DCE is the Distributed File System
DFS. Access to DFS requires authentication and authorization, and when
one uses a Kerberized network utility such as telnet, a forwarded
Kerberos ticket can be used to establish the DCE context to allow
access to DFS.
NEW TO THIS RELEASE
This release introduces sharing of a DCE context, and PAG, and allows
any Kerberized application to establish or share the context. This is
made possible by using an undocumented feature of DCE which is on at
least the Transarc and IBM releases of DCE 1.1.
I am in the process of trying to get this contributed to the general
DCE 1.2.2 release as a patch, so it could be included in other vendors
products. HP has expressed interest in doing this, as well as the
OpenGroup if the modification is contributed. You can help by
requesting Transarc and/or IBM to submit this modification to the
OpenGroup and ask your vendor to adopt this modification.
The feature is a modification to the setpag() system call which will
allow an authorized process to set the PAG to a specific value, and
thus allow unrelated processes to share the same PAG.
This then allows the Kerberized daemons such as kshd, to exec a DCE
module which established the DCE context. Kshd then sets the
KRB5CCNAME environment variable and then issues the setpag() to use
this context. This solves the linking problem. This is done via the
k5dfspag.c routine.
The k5dfspag.c code is compiled with the lib/krb5/os routines and
included in the libkrb5. A daemon calls krb5_dfs_pag after the
krb5_kuserok has determined that the Kerberos principal and local
userid pair are acceptable. This should be done early so as to give
the daemon access to the home directory which may be located on DFS.
If the .k5login file is used by krb5_kuserok it will need to be
accessed by the daemon and will need special ACL handling.
The krb5_dfs_pag routine will exec the k5dcecon module to do all the
real work. Upon return, if a PAG is obtained, krb5_dfs_pag with set
the PAG for the current process to the returned PAG value. It will
also set the KRB5CCNAME environment as well. Under DCE the PAG value
is the nnnnnnn part of the name of the cache:
FILE:/opt/dcelocal/var/security/creds/dcecred_nnnnnnnn.
The k5dcecon routine will attempt to use TGT which may have been
forwarded, to convert it to a DCE context. If there is no TGT, an
attempt will be made to join an existing PAG for the local userid, and
Kerberos principal. If there are existing PAGs, and a forwarded TGT,
k5dcecon will check the lifetime of the forwarded TGT, and if it is
less then the lifetime of the PAG, it will just join the PAG. If it
is greater, it will refresh the PAG using the forwarded TGT.
This approach has the advantage of not requiring many new tickets from
having to be obtained, and allows one to refresh a DCE context, or use
an already established context.
If the system also has AFS, the AFS krb5_afs_pag should be called
after the krb5_dfs_pag, since cache pointed at via the KRB5CCNAME may
have changed, such as if a DFS PAG has been joined. The AFS code does
not have the capability to join an existing AFS PAG, but can use the
same cache which might already had a
afsx/<afs.cell.name>@<k5.realm.name> service ticket.
WHAT'S IN THIS RELEASE
The k5prelogin, k5dcelogin, k5afslogin (with ak5log) were designed to
be slipped in between telnetd or klogind and login.krb5. They would
use a forwarded Kerberos ticket to establish a DCE context. They are
the older programs which are included here. They work on all DCE
platforms, and don't take advantage of the undocumented setpag
feature. (A version of k5dcelogin is being included with DCE 1.2.2)
K5dcecon is the new program which can be used to create, update or
join a DCE context. k5dcecon returns KRB5CCNAME string which contains
the PAG.
k5dfspag.c is to be built in the MIT Kerberos 5 release 1.0 patchlevel
1 and added to the libkrb5. It will exec k5dcecon and upon return set
the KRB5CCNAME and PAG. Mods to Kerberized klogind, rshd, telnetd,
ftpd are available to use the k5dfspag.
Testpag.c is a test programs to see if the PAG can be set.
The cpwkey.c routine can be used to change a key in the DCE registry,
by adding the key directly, or by setting the salt/pepper and password
or by providing the key and the pepper. This could be useful when
coping keys from a K4 or AFS database to DCE. It can also be used when
setting a DCE to K5 cross-cell key. This program is a test program
For mass inserts, it should be rewritten to read from stdin.
K5dcelogin can also be called directly, much like dce_login.
I use the following commands in effect do the same thing as dce_login
and get a forwardable ticket, DCE context and an AFS token:
#!/bin/csh
# simulate a dce_login using krb5 kinit and k5dcelogin
#
setenv KRB5CCNAME FILE:/tmp/krb5cc_p$$
/krb5/bin/kinit -f
exec /krb5/sbin/k5dcelogin /krb5/sbin/k5afslogin /bin/csh
#exec /krb5/sbin/k5dcelogin /bin/csh
This could be useful in a mixed cell where "AS_REQ" messages are
handled by a K5 KDC, but DCE RPCs are handled by the DCE security
server.
TESTING THE SETPAG
The krb5_dfs_pag routine relies on an undocumented feature which is
in the AIX and Transarc Solaris ports of DCE and has been recently
added to the SGI version. To test if this feature is present
on some other DFS implementation use the testpag routine.
The testpag routine attempts to set a PAG value to one you supply. It
uses the afs_syscall with the afs_setpag, and passes the supplied
PAG value as the next parameter. On an unmodifed system, this
will be ignored, and a new will be set. You should also check that
if run as a user, you cannot join a PAG owned by another user.
When run as root, any PAG should be usable.
On a machine with DFS running, do a dce_login to get a DCE context and
PAG. ECHO the KRB5CCNAME and look at the nnnnnnnn at the end. It
should look like an 8 char hex value, which may be 41ffxxxx on some
systems.
Su to root and unsetenv KRB5CCNAME. Do a testpag -n nnnnnnnn where
nnnnnnnn is the PAG obtained for the above name.
It should look like this example on an AIX 4.1.4 system:
pembroke# ./testpag -n 63dc9997
calling k5dcepag newpag=63dc9997
PAG returned = 63dc9997
You will be running under a new shell with the PAG and KRB5CCNAME set.
If the PAG returned is the same as the newpag, then it worked. You can
further verify this by doing a DCE klist, cd to DFS and a DCE klist
again. The klist should show some tickets for DFS servers.
If the PAG returned is not the same, and repeated attempts show a
returned PAG decremented by 1 from the previous returned PAG, then
this system does not have the modification For example:
# ./testpag -n 41fffff9
calling k5dcepag newpag=41fffff9
PAG returned = 41fffff8
# ./testpag -n 41fffff9
calling k5dcepag newpag=41fffff9
PAG returned = 41fffff7
In this case the syscall is ignoring the newpag parameter.
Running it with -n 0 should get the next PAG value with or without
this modification.
If the DFS kernel extensions are not installed, you would get
something like this:
caliban.ctd.anl.gov% ./testpag -n 012345678
calling k5dcepag newpag=012345678
Setpag failed with a system error
PAG returned = ffffffff
Not a good pag value
If you DFS implementation does not have this modification, you could
attempt to install it yourself. But this requires source and requires
modifications to the kernel extensions. At the end of this note is an
untested sample using the DCE 1.2.2 source code. You can also contact
your system vendor and ask for this modification.
UNICOS has a similar function setppag(newpag) which can be used to set
the PAG of the parent. Contact me if you are interested.
HOW TO INSTALL
Examine the k5dfspag.c file to make sure the DFS syscalls are correct
for your platform. See the /opt/dcelocal/share/include/dcedfs/syscall.h
on Solaris for example.
You should build the testpag routine and make sure it works before
adding all the other mods. If it fails you can still use the klogind
and telnetd with the k5prelogin and k5dcelogin code.
If you intend to install with a prefix other then /krb5, change:
DPAGAIX and K5DCECON in k5dfspag.c; the three references in
k5prelogin.c; and the DESTDIR in the Makefile.
Get k5101.cdiff.xxxxxx.tar file and install the mods for ANL_DFS_PAG
and ANL_DCE to the MIT Kerberos 5 source. These mods turn on some DCE
related changes and the calls to krb5_dfs_pag.
Symlink or copy the k5dfspag.c to the src/lib/krb5/os directory.
Add the -DANL_DFS_PAG and -DANL_DCE flags to the configuration.
Configure and Build the Kerberos v5.
Modify the k5dce Makefile for your system.
Build the k5dcecon and related programs.
Install both the MIT Kerberos v5 and the k5dcecon and dpagaix if AIX.
The makefile can also build k5dcelogin and k5prelogin. The install
can install k5dcelogin, k5prelogin and update the links for login.krb5
-> k5prelogin and moving login.krb5 to login.k5. If you will be using
the k5dcecon/k5dfspag with the Kerberos mods, you don't need
k5prelogin, or the links changed, and may not need k5dcelogin.
Note that Transarc has obfuscated the entries to the lib, and
the 1.0.3a is different from the 1.1. You may need to build two
versions of the k5dcelogin and/or k5dcecon one for each.
AIX ONLY
The dpagaix routine is needed for AIX because of the way they do the
syscalls.
The following fix.aix.libdce.mk is not needed if dce 2.1.0.21
has been installed. This PTF exposed the needed entrypoints.
The fix.aix.libdce.mk is a Makefile for AIX 4.x to add the required
external entry points to the libdce.a. These are needed by k5dcecon
and k5dcelogin. A bug report was submitted to IBM on this, and it was
rejected. But since DCE 1.2.2 will have a k5dcelogin, this should not
be needed with 1.2.2
Copy /usr/lib/libdce.a to /usr/libdce.a.orig before starting. Copy the
makefile to its own directory. It will create a new libdce.a which you
need to copy back to /usr/lib/libdce.a You will need to reboot the
machine. See the /usr/lpp/dce/examples/inst/README.AIX for a similar
procedure. IBM was not responsive in a request to have these added.

/*
* k5dcecon - Program to convert a K5 TGT to a DCE context,
* for use with DFS and its PAG.
*
* The program is designed to be called as a sub process,
* and return via stdout the name of the cache which implies
* the PAG which should be used. This program itself does not
* use the cache or PAG itself, so the PAG in the kernel for
* this program may not be set.
*
* The calling program can then use the name of the cache
* to set the KRB5CCNAME and PAG for its self and its children.
*
* If no ticket was passed, an attemplt to join an existing
* PAG will be made.
*
* If a forwarded K5 TGT is passed in, either a new DCE
* context will be created, or an existing one will be updated.
* If the same ticket was already used to create an existing
* context, it will be joined instead.
*
* Parts of this program are based on k5dceauth,c which was
* given to me by HP and by the k5dcelogin.c which I developed.
* A slightly different version of k5dcelogin.c, was added to
* DCE 1.2.2

ffttpp - ARPANET file transfer program
SSYYNNOOPPSSIISS
ffttpp [--tt] [--vv] [--dd] [--ii] [--nn] [--gg] [--pp] [--ll] [_h_o_s_t]
DDEESSCCRRIIPPTTIIOONN
FFttpp is the user interface to the ARPANET standard File Transfer Protocol.
The program allows a user to transfer files to and from a remote network
site.
Modifications has been made so that it almost follows the ftpsec Internet
draft.
Options may be specified at the command line, or to the command inter-
preter.
--tt Enables packet tracing.
--vv Verbose option forces ffttpp to show all responses from the remote
server, as well as report on data transfer statistics.
--nn Restrains ffttpp from attempting ``auto-login'' upon initial connec-
tion. If auto-login is enabled, ffttpp will check the _._n_e_t_r_c (see be-
low) file in the user's home directory for an entry describing an
account on the remote machine. If no entry exists, ffttpp will prompt
for the remote machine login name (default is the user identity on
the local machine), and, if necessary, prompt for a password and an
account with which to login.
--ii Turns off interactive prompting during multiple file transfers.
--pp Turn on passive mode.
--dd Enables debugging.
--gg Disables file name globbing.
--ll Disables command line editing.
The client host with which ffttpp is to communicate may be specified on the
command line. If this is done, ffttpp will immediately attempt to establish
a connection to an FTP server on that host; otherwise, ffttpp will enter its
command interpreter and await instructions from the user. When ffttpp is
awaiting commands from the user the prompt `ftp>' is provided to the us-
er. The following commands are recognized by ffttpp:
!! [_c_o_m_m_a_n_d [_a_r_g_s]]
Invoke an interactive shell on the local machine. If there
are arguments, the first is taken to be a command to execute
directly, with the rest of the arguments as its arguments.
$$ _m_a_c_r_o_-_n_a_m_e [_a_r_g_s]
Execute the macro _m_a_c_r_o_-_n_a_m_e that was defined with the mmaaccddeeff
command. Arguments are passed to the macro unglobbed.
aaccccoouunntt [_p_a_s_s_w_d]
Supply a supplemental password required by a remote system
for access to resources once a login has been successfully
completed. If no argument is included, the user will be
prompted for an account password in a non-echoing input mode.
aappppeenndd _l_o_c_a_l_-_f_i_l_e [_r_e_m_o_t_e_-_f_i_l_e]
Append a local file to a file on the remote machine. If
_r_e_m_o_t_e_-_f_i_l_e is left unspecified, the local file name is used
in naming the remote file after being altered by any nnttrraannss
or nnmmaapp setting. File transfer uses the current settings for
ttyyppee, ffoorrmmaatt, mmooddee, and ssttrruuccttuurree.
aasscciiii Set the file transfer ttyyppee to network ASCII. This is the de-
fault type.
bbeellll Arrange that a bell be sounded after each file transfer com-
mand is completed.
bbiinnaarryy Set the file transfer ttyyppee to support binary image transfer.
bbyyee Terminate the FTP session with the remote server and exit
ffttpp. An end of file will also terminate the session and exit.
ccaassee Toggle remote computer file name case mapping during mmggeett
commands. When ccaassee is on (default is off), remote computer
file names with all letters in upper case are written in the
local directory with the letters mapped to lower case.
ccdd _r_e_m_o_t_e_-_d_i_r_e_c_t_o_r_y
Change the working directory on the remote machine to _r_e_m_o_t_e_-
_d_i_r_e_c_t_o_r_y.
ccdduupp Change the remote machine working directory to the parent of
the current remote machine working directory.
cchhmmoodd _m_o_d_e _f_i_l_e_-_n_a_m_e
Change the permission modes of the file _f_i_l_e_-_n_a_m_e on the re-
mote sytem to _m_o_d_e.
cclloossee Terminate the FTP session with the remote server, and return
to the command interpreter. Any defined macros are erased.
ccrr Toggle carriage return stripping during ascii type file re-
trieval. Records are denoted by a carriage return/linefeed
sequence during ascii type file transfer. When ccrr is on (the
default), carriage returns are stripped from this sequence to
conform with the UNIX single linefeed record delimiter.
Records on non-UNIX remote systems may contain single line-
feeds; when an ascii type transfer is made, these linefeeds
may be distinguished from a record delimiter only when ccrr is
off.
ddeelleettee _r_e_m_o_t_e_-_f_i_l_e
Delete the file _r_e_m_o_t_e_-_f_i_l_e on the remote machine.
ddeebbuugg [_d_e_b_u_g_-_v_a_l_u_e]
Toggle debugging mode. If an optional _d_e_b_u_g_-_v_a_l_u_e is speci-
fied it is used to set the debugging level. When debugging
is on, ffttpp prints each command sent to the remote machine,
preceded by the string `-->'
ddiirr [_r_e_m_o_t_e_-_d_i_r_e_c_t_o_r_y] [_l_o_c_a_l_-_f_i_l_e]
Print a listing of the directory contents in the directory,
_r_e_m_o_t_e_-_d_i_r_e_c_t_o_r_y, and, optionally, placing the output in
_l_o_c_a_l_-_f_i_l_e. If interactive prompting is on, ffttpp will prompt
the user to verify that the last argument is indeed the tar-
get local file for receiving ddiirr output. If no directory is
specified, the current working directory on the remote ma-
chine is used. If no local file is specified, or _l_o_c_a_l_-_f_i_l_e
is --, output comes to the terminal.
ddiissccoonnnneecctt A synonym for _c_l_o_s_e.
ffoorrmm _f_o_r_m_a_t
Set the file transfer ffoorrmm to _f_o_r_m_a_t. The default format is
``file''.
ggeett _r_e_m_o_t_e_-_f_i_l_e [_l_o_c_a_l_-_f_i_l_e]
Retrieve the _r_e_m_o_t_e_-_f_i_l_e and store it on the local machine.
If the local file name is not specified, it is given the same
name it has on the remote machine, subject to alteration by
the current ccaassee, nnttrraannss, and nnmmaapp settings. The current
settings for ttyyppee, ffoorrmm, mmooddee, and ssttrruuccttuurree are used while
transferring the file.
gglloobb Toggle filename expansion for mmddeelleettee, mmggeett and mmppuutt. If
globbing is turned off with gglloobb, the file name arguments are
taken literally and not expanded. Globbing for mmppuutt is done
as in csh(1). For mmddeelleettee and mmggeett, each remote file name is
expanded separately on the remote machine and the lists are
not merged. Expansion of a directory name is likely to be
different from expansion of the name of an ordinary file: the
exact result depends on the foreign operating system and ftp
server, and can be previewed by doing `mls remote-files -'.
As a security measure, remotely globbed files that starts
with `/' or contains `../', will not be automatically re-
ceived. If you have interactive prompting turned off, these
filenames will be ignored. Note: mmggeett and mmppuutt are not meant
to transfer entire directory subtrees of files. That can be
done by transferring a tar(1) archive of the subtree (in bi-
nary mode).
hhaasshh Toggle hash-sign (``#'') printing for each data block trans-
ferred. The size of a data block is 1024 bytes.
hheellpp [_c_o_m_m_a_n_d]
Print an informative message about the meaning of _c_o_m_m_a_n_d. If
no argument is given, ffttpp prints a list of the known com-
mands.
iiddllee [_s_e_c_o_n_d_s]
Set the inactivity timer on the remote server to _s_e_c_o_n_d_s sec-
onds. If _s_e_c_o_n_d_s is omitted, the current inactivity timer is
printed.
llccdd [_d_i_r_e_c_t_o_r_y]
Change the working directory on the local machine. If no
_d_i_r_e_c_t_o_r_y is specified, the user's home directory is used.
llss [_r_e_m_o_t_e_-_d_i_r_e_c_t_o_r_y] [_l_o_c_a_l_-_f_i_l_e]
Print a listing of the contents of a directory on the remote
machine. The listing includes any system-dependent informa-
tion that the server chooses to include; for example, most
UNIX systems will produce output from the command `ls -l'.
(See also nnlliisstt.) If _r_e_m_o_t_e_-_d_i_r_e_c_t_o_r_y is left unspecified,
the current working directory is used. If interactive
prompting is on, ffttpp will prompt the user to verify that the
last argument is indeed the target local file for receiving
llss output. If no local file is specified, or if _l_o_c_a_l_-_f_i_l_e
is `--', the output is sent to the terminal.
mmaaccddeeff _m_a_c_r_o_-_n_a_m_e
Define a macro. Subsequent lines are stored as the macro
_m_a_c_r_o_-_n_a_m_e; a null line (consecutive newline characters in a
file or carriage returns from the terminal) terminates macro
input mode. There is a limit of 16 macros and 4096 total
characters in all defined macros. Macros remain defined un-
til a cclloossee command is executed. The macro processor inter-
prets `$' and `\' as special characters. A `$' followed by a
number (or numbers) is replaced by the corresponding argument
on the macro invocation command line. A `$' followed by an
`i' signals that macro processor that the executing macro is
to be looped. On the first pass `$i' is replaced by the
first argument on the macro invocation command line, on the
second pass it is replaced by the second argument, and so on.
A `\' followed by any character is replaced by that charac-
ter. Use the `\' to prevent special treatment of the `$'.
mmddeelleettee [_r_e_m_o_t_e_-_f_i_l_e_s]
Delete the _r_e_m_o_t_e_-_f_i_l_e_s on the remote machine.
mmddiirr _r_e_m_o_t_e_-_f_i_l_e_s _l_o_c_a_l_-_f_i_l_e
Like ddiirr, except multiple remote files may be specified. If
interactive prompting is on, ffttpp will prompt the user to ver-
ify that the last argument is indeed the target local file
for receiving mmddiirr output.
mmggeett _r_e_m_o_t_e_-_f_i_l_e_s
Expand the _r_e_m_o_t_e_-_f_i_l_e_s on the remote machine and do a ggeett
for each file name thus produced. See gglloobb for details on
the filename expansion. Resulting file names will then be
processed according to ccaassee, nnttrraannss, and nnmmaapp settings.
Files are transferred into the local working directory, which
can be changed with `lcd directory'; new local directories
can be created with `! mkdir directory'.
mmkkddiirr _d_i_r_e_c_t_o_r_y_-_n_a_m_e
Make a directory on the remote machine.
mmllss _r_e_m_o_t_e_-_f_i_l_e_s _l_o_c_a_l_-_f_i_l_e
Like nnlliisstt, except multiple remote files may be specified,
and the _l_o_c_a_l_-_f_i_l_e must be specified. If interactive prompt-
ing is on, ffttpp will prompt the user to verify that the last
argument is indeed the target local file for receiving mmllss
output.
mmooddee [_m_o_d_e_-_n_a_m_e]
Set the file transfer mmooddee to _m_o_d_e_-_n_a_m_e. The default mode is
``stream'' mode.
mmooddttiimmee _f_i_l_e_-_n_a_m_e
Show the last modification time of the file on the remote ma-
chine.
mmppuutt _l_o_c_a_l_-_f_i_l_e_s
Expand wild cards in the list of local files given as argu-
ments and do a ppuutt for each file in the resulting list. See
gglloobb for details of filename expansion. Resulting file names
will then be processed according to nnttrraannss and nnmmaapp settings.
nneewweerr _f_i_l_e_-_n_a_m_e
Get the file only if the modification time of the remote file
is more recent that the file on the current system. If the
file does not exist on the current system, the remote file is
considered nneewweerr. Otherwise, this command is identical to
_g_e_t.
nnlliisstt [_r_e_m_o_t_e_-_d_i_r_e_c_t_o_r_y] [_l_o_c_a_l_-_f_i_l_e]
Print a list of the files in a directory on the remote ma-
chine. If _r_e_m_o_t_e_-_d_i_r_e_c_t_o_r_y is left unspecified, the current
working directory is used. If interactive prompting is on,
ffttpp will prompt the user to verify that the last argument is
indeed the target local file for receiving nnlliisstt output. If
no local file is specified, or if _l_o_c_a_l_-_f_i_l_e is --, the output
is sent to the terminal.
nnmmaapp [_i_n_p_a_t_t_e_r_n _o_u_t_p_a_t_t_e_r_n]
Set or unset the filename mapping mechanism. If no arguments
are specified, the filename mapping mechanism is unset. If
arguments are specified, remote filenames are mapped during
mmppuutt commands and ppuutt commands issued without a specified re-
mote target filename. If arguments are specified, local
filenames are mapped during mmggeett commands and ggeett commands
issued without a specified local target filename. This com-
mand is useful when connecting to a non-UNIX remote computer
with different file naming conventions or practices. The
mapping follows the pattern set by _i_n_p_a_t_t_e_r_n and _o_u_t_p_a_t_t_e_r_n.
[_I_n_p_a_t_t_e_r_n] is a template for incoming filenames (which may
have already been processed according to the nnttrraannss and ccaassee
settings). Variable templating is accomplished by including
the sequences `$1', `$2', ..., `$9' in _i_n_p_a_t_t_e_r_n. Use `\' to
prevent this special treatment of the `$' character. All
other characters are treated literally, and are used to de-
termine the nnmmaapp [_i_n_p_a_t_t_e_r_n] variable values. For example,
given _i_n_p_a_t_t_e_r_n $1.$2 and the remote file name "mydata.data",
$1 would have the value "mydata", and $2 would have the value
"data". The _o_u_t_p_a_t_t_e_r_n determines the resulting mapped file-
name. The sequences `$1', `$2', ...., `$9' are replaced by
any value resulting from the _i_n_p_a_t_t_e_r_n template. The se-
quence `$0' is replace by the original filename. Additional-
ly, the sequence `[_s_e_q_1, _s_e_q_2]' is replaced by [_s_e_q_1] if _s_e_q_1
is not a null string; otherwise it is replaced by _s_e_q_2. For
example, the command
nmap $1.$2.$3 [$1,$2].[$2,file]
would yield the output filename "myfile.data" for input file-
names "myfile.data" and "myfile.data.old", "myfile.file" for
the input filename "myfile", and "myfile.myfile" for the in-
put filename ".myfile". Spaces may be included in
_o_u_t_p_a_t_t_e_r_n, as in the example: `nmap $1 sed "s/ *$//" > $1'
. Use the `\' character to prevent special treatment of the
`$','[','[', and `,' characters.
nnttrraannss [_i_n_c_h_a_r_s [_o_u_t_c_h_a_r_s]]
Set or unset the filename character translation mechanism.
If no arguments are specified, the filename character trans-
lation mechanism is unset. If arguments are specified, char-
acters in remote filenames are translated during mmppuutt com-
mands and ppuutt commands issued without a specified remote tar-
get filename. If arguments are specified, characters in lo-
cal filenames are translated during mmggeett commands and ggeett
commands issued without a specified local target filename.
This command is useful when connecting to a non-UNIX remote
computer with different file naming conventions or practices.
Characters in a filename matching a character in _i_n_c_h_a_r_s are
replaced with the corresponding character in _o_u_t_c_h_a_r_s. If the
character's position in _i_n_c_h_a_r_s is longer than the length of
_o_u_t_c_h_a_r_s, the character is deleted from the file name.
ooppeenn _h_o_s_t [_p_o_r_t]
Establish a connection to the specified _h_o_s_t FTP server. An
optional port number may be supplied, in which case, ffttpp will
attempt to contact an FTP server at that port. If the aauuttoo--
llooggiinn option is on (default), ffttpp will also attempt to auto-
matically log the user in to the FTP server (see below).
ppaassssiivvee Toggle passive mode. If passive mode is turned on (default
is off), the ftp client will send a PASV command for all data
connections instead of the usual PORT command. The PASV com-
mand requests that the remote server open a port for the data
connection and return the address of that port. The remote
server listens on that port and the client connects to it.
When using the more traditional PORT command, the client lis-
tens on a port and sends that address to the remote server,
who connects back to it. Passive mode is useful when using
ffttpp through a gateway router or host that controls the direc-
tionality of traffic. (Note that though ftp servers are re-
quired to support the PASV command by RFC 1123, some do not.)
pprroommpptt Toggle interactive prompting. Interactive prompting occurs
during multiple file transfers to allow the user to selec-
tively retrieve or store files. If prompting is turned off
(default is on), any mmggeett or mmppuutt will transfer all files,
and any mmddeelleettee will delete all files.
pprrooxxyy _f_t_p_-_c_o_m_m_a_n_d
Execute an ftp command on a secondary control connection.
This command allows simultaneous connection to two remote ftp
servers for transferring files between the two servers. The
first pprrooxxyy command should be an ooppeenn, to establish the sec-
ondary control connection. Enter the command "proxy ?" to
see other ftp commands executable on the secondary connec-
tion. The following commands behave differently when pref-
aced by pprrooxxyy: ooppeenn will not define new macros during the au-
to-login process, cclloossee will not erase existing macro defini-
tions, ggeett and mmggeett transfer files from the host on the pri-
mary control connection to the host on the secondary control
connection, and ppuutt, mmppuutt, and aappppeenndd transfer files from the
host on the secondary control connection to the host on the
primary control connection. Third party file transfers de-
pend upon support of the ftp protocol PASV command by the
server on the secondary control connection.
ppuutt _l_o_c_a_l_-_f_i_l_e [_r_e_m_o_t_e_-_f_i_l_e]
Store a local file on the remote machine. If _r_e_m_o_t_e_-_f_i_l_e is
left unspecified, the local file name is used after process-
ing according to any nnttrraannss or nnmmaapp settings in naming the
remote file. File transfer uses the current settings for
ttyyppee, ffoorrmmaatt, mmooddee, and ssttrruuccttuurree.
ppwwdd Print the name of the current working directory on the remote
machine.
qquuiitt A synonym for bbyyee.
qquuoottee _a_r_g_1 _a_r_g_2 _._._.
The arguments specified are sent, verbatim, to the remote FTP
server.
rreeccvv _r_e_m_o_t_e_-_f_i_l_e [_l_o_c_a_l_-_f_i_l_e]
A synonym for get.
rreeggeett _r_e_m_o_t_e_-_f_i_l_e [_l_o_c_a_l_-_f_i_l_e]
Reget acts like get, except that if _l_o_c_a_l_-_f_i_l_e exists and is
smaller than _r_e_m_o_t_e_-_f_i_l_e, _l_o_c_a_l_-_f_i_l_e is presumed to be a par-
tially transferred copy of _r_e_m_o_t_e_-_f_i_l_e and the transfer is
continued from the apparent point of failure. This command
is useful when transferring very large files over networks
that are prone to dropping connections.
rreemmootteehheellpp [_c_o_m_m_a_n_d_-_n_a_m_e]
Request help from the remote FTP server. If a _c_o_m_m_a_n_d_-_n_a_m_e
is specified it is supplied to the server as well.
rreemmootteessttaattuuss [_f_i_l_e_-_n_a_m_e]
With no arguments, show status of remote machine. If _f_i_l_e_-
_n_a_m_e is specified, show status of _f_i_l_e_-_n_a_m_e on remote ma-
chine.
rreennaammee [_f_r_o_m] [_t_o]
Rename the file _f_r_o_m on the remote machine, to the file _t_o.
rreesseett Clear reply queue. This command re-synchronizes command/re-
ply sequencing with the remote ftp server. Resynchronization
may be necessary following a violation of the ftp protocol by
the remote server.
rreessttaarrtt _m_a_r_k_e_r
Restart the immediately following ggeett or ppuutt at the indicated
_m_a_r_k_e_r. On UNIX systems, marker is usually a byte offset into
the file.
rrmmddiirr _d_i_r_e_c_t_o_r_y_-_n_a_m_e
Delete a directory on the remote machine.
rruunniiqquuee Toggle storing of files on the local system with unique file-
names. If a file already exists with a name equal to the
target local filename for a ggeett or mmggeett command, a ".1" is
appended to the name. If the resulting name matches another
existing file, a ".2" is appended to the original name. If
this process continues up to ".99", an error message is
printed, and the transfer does not take place. The generated
unique filename will be reported. Note that rruunniiqquuee will not
affect local files generated from a shell command (see be-
low). The default value is off.
sseenndd _l_o_c_a_l_-_f_i_l_e [_r_e_m_o_t_e_-_f_i_l_e]
A synonym for put.
sseennddppoorrtt Toggle the use of PORT commands. By default, ffttpp will at-
tempt to use a PORT command when establishing a connection
for each data transfer. The use of PORT commands can prevent
delays when performing multiple file transfers. If the PORT
command fails, ffttpp will use the default data port. When the
use of PORT commands is disabled, no attempt will be made to
use PORT commands for each data transfer. This is useful for
certain FTP implementations which do ignore PORT commands
but, incorrectly, indicate they've been accepted.
ssiittee _a_r_g_1 _a_r_g_2 _._._.
The arguments specified are sent, verbatim, to the remote FTP
server as a SITE command.
ssiizzee _f_i_l_e_-_n_a_m_e
Return size of _f_i_l_e_-_n_a_m_e on remote machine.
ssttaattuuss Show the current status of ffttpp.
ssttrruucctt [_s_t_r_u_c_t_-_n_a_m_e]
Set the file transfer _s_t_r_u_c_t_u_r_e to _s_t_r_u_c_t_-_n_a_m_e. By default
``stream'' structure is used.
ssuunniiqquuee Toggle storing of files on remote machine under unique file
names. Remote ftp server must support ftp protocol STOU com-
mand for successful completion. The remote server will re-
port unique name. Default value is off.
ssyysstteemm Show the type of operating system running on the remote ma-
chine.
tteenneexx Set the file transfer type to that needed to talk to TENEX
machines.
ttrraaccee Toggle packet tracing.
ttyyppee [_t_y_p_e_-_n_a_m_e]
Set the file transfer ttyyppee to _t_y_p_e_-_n_a_m_e. If no type is speci-
fied, the current type is printed. The default type is net-
work ASCII.
uummaasskk [_n_e_w_m_a_s_k]
Set the default umask on the remote server to _n_e_w_m_a_s_k. If
_n_e_w_m_a_s_k is omitted, the current umask is printed.
uusseerr _u_s_e_r_-_n_a_m_e [_p_a_s_s_w_o_r_d] [_a_c_c_o_u_n_t]
Identify yourself to the remote FTP server. If the _p_a_s_s_w_o_r_d
is not specified and the server requires it, ffttpp will prompt
the user for it (after disabling local echo). If an _a_c_c_o_u_n_t
field is not specified, and the FTP server requires it, the
user will be prompted for it. If an _a_c_c_o_u_n_t field is speci-
fied, an account command will be relayed to the remote server
after the login sequence is completed if the remote server
did not require it for logging in. Unless ffttpp is invoked
with ``auto-login'' disabled, this process is done automati-
cally on initial connection to the FTP server.
vveerrbboossee Toggle verbose mode. In verbose mode, all responses from the
FTP server are displayed to the user. In addition, if ver-
bose is on, when a file transfer completes, statistics re-
garding the efficiency of the transfer are reported. By de-
fault, verbose is on.
?? [_c_o_m_m_a_n_d]
A synonym for help.
The following command can be used with ftpsec-aware servers.
pprroott _c_l_e_a_r | _s_a_f_e | _c_o_n_f_i_d_e_n_t_i_a_l | _p_r_i_v_a_t_e
Set the data protection level to the requested level.
The following command can be used with ftp servers that has implemented
the KAUTH site command.
kkaauutthh [_p_r_i_n_c_i_p_a_l]
Obtain remote tickets.
Command arguments which have embedded spaces may be quoted with quote `"'
marks.
AABBOORRTTIINNGG AA FFIILLEE TTRRAANNSSFFEERR
To abort a file transfer, use the terminal interrupt key (usually Ctrl-
C). Sending transfers will be immediately halted. Receiving transfers
will be halted by sending a ftp protocol ABOR command to the remote serv-
er, and discarding any further data received. The speed at which this is
accomplished depends upon the remote server's support for ABOR process-
ing. If the remote server does not support the ABOR command, an `ftp>'
prompt will not appear until the remote server has completed sending the
requested file.
The terminal interrupt key sequence will be ignored when ffttpp has complet-
ed any local processing and is awaiting a reply from the remote server.
A long delay in this mode may result from the ABOR processing described
above, or from unexpected behavior by the remote server, including viola-
tions of the ftp protocol. If the delay results from unexpected remote
server behavior, the local ffttpp program must be killed by hand.
FFIILLEE NNAAMMIINNGG CCOONNVVEENNTTIIOONNSS
Files specified as arguments to ffttpp commands are processed according to
the following rules.
1. If the file name `--' is specified, the _s_t_d_i_n (for reading) or _s_t_d_o_u_t
(for writing) is used.
2. If the first character of the file name is `|', the remainder of the
argument is interpreted as a shell command. FFttpp then forks a shell,
using popen(3) with the argument supplied, and reads (writes) from
the stdout (stdin). If the shell command includes spaces, the argu-
ment must be quoted; e.g. ``" ls -lt"''. A particularly useful ex-
ample of this mechanism is: ``dir more''.
3. Failing the above checks, if ``globbing'' is enabled, local file
names are expanded according to the rules used in the csh(1); c.f.
the gglloobb command. If the ffttpp command expects a single local file
(.e.g. ppuutt), only the first filename generated by the "globbing"
operation is used.
4. For mmggeett commands and ggeett commands with unspecified local file
names, the local filename is the remote filename, which may be al-
tered by a ccaassee, nnttrraannss, or nnmmaapp setting. The resulting filename
may then be altered if rruunniiqquuee is on.
5. For mmppuutt commands and ppuutt commands with unspecified remote file
names, the remote filename is the local filename, which may be al-
tered by a nnttrraannss or nnmmaapp setting. The resulting filename may then
be altered by the remote server if ssuunniiqquuee is on.
FFIILLEE TTRRAANNSSFFEERR PPAARRAAMMEETTEERRSS
The FTP specification specifies many parameters which may affect a file
transfer. The ttyyppee may be one of ``ascii'', ``image'' (binary),
``ebcdic'', and ``local byte size'' (for PDP-10's and PDP-20's mostly).
FFttpp supports the ascii and image types of file transfer, plus local byte
size 8 for tteenneexx mode transfers.
FFttpp supports only the default values for the remaining file transfer pa-
rameters: mmooddee, ffoorrmm, and ssttrruucctt.
TTHHEE ..nneettrrcc FFIILLEE
The _._n_e_t_r_c file contains login and initialization information used by the
auto-login process. It resides in the user's home directory. The fol-
lowing tokens are recognized; they may be separated by spaces, tabs, or
new-lines:
mmaacchhiinnee _n_a_m_e
Identify a remote machine _n_a_m_e. The auto-login process searches
the _._n_e_t_r_c file for a mmaacchhiinnee token that matches the remote ma-
chine specified on the ffttpp command line or as an ooppeenn command
argument. Once a match is made, the subsequent _._n_e_t_r_c tokens
are processed, stopping when the end of file is reached or an-
other mmaacchhiinnee or a ddeeffaauulltt token is encountered.
ddeeffaauulltt This is the same as mmaacchhiinnee _n_a_m_e except that ddeeffaauulltt matches
any name. There can be only one ddeeffaauulltt token, and it must be
after all mmaacchhiinnee tokens. This is normally used as:
default login anonymous password user@site
thereby giving the user _a_u_t_o_m_a_t_i_c anonymous ftp login to ma-
chines not specified in _._n_e_t_r_c. This can be overridden by using
the --nn flag to disable auto-login.
llooggiinn _n_a_m_e
Identify a user on the remote machine. If this token is pre-
sent, the auto-login process will initiate a login using the
specified _n_a_m_e.
ppaasssswwoorrdd _s_t_r_i_n_g
Supply a password. If this token is present, the auto-login
process will supply the specified string if the remote server
requires a password as part of the login process. Note that if
this token is present in the _._n_e_t_r_c file for any user other
than _a_n_o_n_y_m_o_u_s, ffttpp will abort the auto-login process if the
_._n_e_t_r_c is readable by anyone besides the user.
aaccccoouunntt _s_t_r_i_n_g
Supply an additional account password. If this token is pre-
sent, the auto-login process will supply the specified string
if the remote server requires an additional account password,
or the auto-login process will initiate an ACCT command if it
does not.
mmaaccddeeff _n_a_m_e
Define a macro. This token functions like the ffttpp mmaaccddeeff com-
mand functions. A macro is defined with the specified name;
its contents begin with the next _._n_e_t_r_c line and continue until
a null line (consecutive new-line characters) is encountered.
If a macro named iinniitt is defined, it is automatically executed
as the last step in the auto-login process.
EENNVVIIRROONNMMEENNTT
FFttpp utilizes the following environment variables.
HOME For default location of a _._n_e_t_r_c file, if one exists.
SHELL For default shell.
SSEEEE AALLSSOO
ftpd(8), _R_F_C_2_2_2_8
HHIISSTTOORRYY
The ffttpp command appeared in 4.2BSD.
BBUUGGSS
Correct execution of many commands depends upon proper behavior by the
remote server.
An error in the treatment of carriage returns in the 4.2BSD ascii-mode
transfer code has been corrected. This correction may result in incor-
rect transfers of binary files to and from 4.2BSD servers using the ascii
type. Avoid this problem by using the binary image type.

ffttppdd - Internet File Transfer Protocol server
SSYYNNOOPPSSIISS
ffttppdd [--aa _a_u_t_h_m_o_d_e] [--ddiillvv] [--gg _u_m_a_s_k] [--pp _p_o_r_t] [--TT _m_a_x_t_i_m_e_o_u_t] [--tt

DDEESSCCRRIIPPTTIIOONN
FFttppdd is the Internet File Transfer Protocol server process. The server
uses the TCP protocol and listens at the port specified in the ``ftp''
service specification; see services(5).
Available options:
--aa Select the level of authentication required. Kerberised login
can not be turned off. The default is to only allow kerberised
login. Other possibilities can be turned on by giving a string
of comma separated flags as argument to --aa. Recognised flags are:
_p_l_a_i_n Allow logging in with plaintext password. The password can
be a(n) OTP or an ordinary password.
_o_t_p Same as _p_l_a_i_n, but only OTP is allowed.
_f_t_p Allow anonymous login.
The following combination modes exists for backwards compatibili-
ty:
_n_o_n_e Same as _p_l_a_i_n_,_f_t_p.
_s_a_f_e Same as _f_t_p.
_u_s_e_r Ignored.
--dd Debugging information is written to the syslog using LOG_FTP.
--gg Anonymous users will get a umask of _u_m_a_s_k.
--ii Open a socket and wait for a connection. This is mainly used for
debugging when ftpd isn't started by inetd.
--ll Each successful and failed ftp(1) session is logged using syslog
with a facility of LOG_FTP. If this option is specified twice,
the retrieve (get), store (put), append, delete, make directory,
remove directory and rename operations and their filename argu-
ments are also logged.
--pp Use _p_o_r_t (a service name or number) instead of the default
_f_t_p_/_t_c_p.
--TT A client may also request a different timeout period; the maximum
period allowed may be set to _t_i_m_e_o_u_t seconds with the --TT option.
The default limit is 2 hours.
--tt The inactivity timeout period is set to _t_i_m_e_o_u_t seconds (the de-
fault is 15 minutes).
--uu Set the initial umask to something else than the default 027.
--vv Verbose mode.
--BB, ----bbuuiillttiinn--llss
use built-in ls to list files
----ggoooodd--cchhaarrss==_s_t_r_i_n_g
allowed anonymous upload filename chars
The file _/_e_t_c_/_n_o_l_o_g_i_n can be used to disable ftp access. If the file ex-
ists, ffttppdd displays it and exits. If the file _/_e_t_c_/_f_t_p_w_e_l_c_o_m_e exists,
ffttppdd prints it before issuing the ``ready'' message. If the file
_/_e_t_c_/_m_o_t_d exists, ffttppdd prints it after a successful login.
The ftp server currently supports the following ftp requests. The case
of the requests is ignored.
Request Description

NLST give name list of files in directory
NOOP do nothing
PASS specify password
PASV prepare for server-to-server transfer
PORT specify data connection port
PWD print the current working directory
QUIT terminate session
REST restart incomplete transfer
RETR retrieve a file

SITE non-standard commands (see next section)
SIZE return size of file
STAT return status of server
STOR store a file
STOU store a file with a unique name
STRU specify data transfer _s_t_r_u_c_t_u_r_e
SYST show operating system type of server system
TYPE specify data transfer _t_y_p_e
USER specify user name
XCUP change to parent of current working directory
(deprecated)
XCWD change working directory (deprecated)
XMKD make a directory (deprecated)

The following commands are specified by RFC2228.
AUTH authentication/security mechanism
ADAT authentication/security data
PROT data channel protection level
PBSZ protection buffer size
MIC integrity protected command
CONF confidentiality protected command
ENC privacy protected command
CCC clear command channel
The following non-standard or UNIX specific commands are supported by the
SITE request.
UMASK change umask, (e.g. SSIITTEE UUMMAASSKK 000022)
IDLE set idle-timer, (e.g. SSIITTEE IIDDLLEE 6600)
CHMOD change mode of a file (e.g. SSIITTEE CCHHMMOODD 775555 ffiilleennaammee)
FIND quickly find a specific file with GNU locate(1).
HELP give help information.
The following Kerberos related site commands are understood.
KAUTH obtain remote tickets.
KLIST show remote tickets
The remaining ftp requests specified in Internet RFC 959 are recognized,
but not implemented. MDTM and SIZE are not specified in RFC 959, but
will appear in the next updated FTP RFC.
The ftp server will abort an active file transfer only when the ABOR com-
mand is preceded by a Telnet "Interrupt Process" (IP) signal and a Telnet
"Synch" signal in the command Telnet stream, as described in Internet RFC
959. If a STAT command is received during a data transfer, preceded by a
Telnet IP and Synch, transfer status will be returned.
FFttppdd interprets file names according to the ``globbing'' conventions used
by csh(1). This allows users to utilize the metacharacters ``*?[]{}~''.
FFttppdd authenticates users according to these rules.
1. If Kerberos authentication is used, the user must pass valid
tickets and the principal must be allowed to login as the re-
mote user.
2. The login name must be in the password data base, and not have
a null password (if kerberos is used the password field is not
checked). In this case a password must be provided by the
client before any file operations may be performed. If the
user has an OTP key, the response from a successful USER com-
mand will include an OTP challenge. The client may choose to
respond with a PASS command giving either a standard password
or an OTP one-time password. The server will automatically de-
termine which type of password it has been given and attempt
to authenticate accordingly. See otp(1) for more information
on OTP authentication.
3. The login name must not appear in the file _/_e_t_c_/_f_t_p_u_s_e_r_s.
4. The user must have a standard shell returned by
getusershell(3).
5. If the user name appears in the file _/_e_t_c_/_f_t_p_c_h_r_o_o_t the ses-
sion's root will be changed to the user's login directory by
chroot(2) as for an ``anonymous'' or ``ftp'' account (see next
item). However, the user must still supply a password. This
feature is intended as a compromise between a fully anonymous
account and a fully privileged account. The account should
also be set up as for an anonymous account.
6. If the user name is ``anonymous'' or ``ftp'', an anonymous ftp
account must be present in the password file (user ``ftp'').
In this case the user is allowed to log in by specifying any
password (by convention an email address for the user should
be used as the password).
In the last case, ffttppdd takes special measures to restrict the client's
access privileges. The server performs a chroot(2) to the home directory
of the ``ftp'' user. In order that system security is not breached, it
is recommended that the ``ftp'' subtree be constructed with care, consid-
er following these guidelines for anonymous ftp.
In general all files should be owned by ``root'', and have non-write per-
missions (644 or 755 depending on the kind of file). No files should be
owned or writable by ``ftp'' (possibly with exception for the
_~_f_t_p_/_i_n_c_o_m_i_n_g, as specified below).
_~_f_t_p The ``ftp'' homedirectory should be owned by root.
_~_f_t_p_/_b_i_n The directory for external programs (such as ls(1)).
These programs must either be statically linked, or you
must setup an environment for dynamic linking when run-
ning chrooted. These programs will be used if present:
ls Used when listing files.
compress
When retrieving a filename that ends in _._Z,
and that file isn't present, ffttppdd will try
to find the filename without _._Z and com-
press it on the fly.
gzip Same as compress, just with files ending in
_._g_z.
gtar Enables retrieval of whole directories as
files ending in _._t_a_r. Can also be combined
with compression. You must use GNU Tar (or
some other that supports the --zz and --ZZ
flags).
locate Will enable ``fast find'' with the SSIITTEE
FFIINNDD command. You must also create a
_l_o_c_a_t_e_d_b file in _~_f_t_p_/_e_t_c.
_~_f_t_p_/_e_t_c If you put copies of the passwd(5) and group(5) files
here, ls will be able to produce owner names rather than
numbers. Remember to remove any passwords from these
files.
The file _m_o_t_d, if present, will be printed after a suc-
cessful login.
_~_f_t_p_/_d_e_v Put a copy of /dev/null(7) here.
_~_f_t_p_/_p_u_b Traditional place to put whatever you want to make pub-
lic.
If you want guests to be able to upload files, create a _~_f_t_p_/_i_n_c_o_m_i_n_g di-
rectory owned by ``root'', and group ``ftp'' with mode 730 (make sure
``ftp'' is member of group ``ftp''). The following restrictions apply to
anonymous users:
++oo Directories created will have mode 700.
++oo Uploaded files will be created with an umask of 777, if not changed
with the --gg option.
++oo These command are not accessible: DDEELLEE, RRMMDD, RRNNTTOO, RRNNFFRR, SSIITTEE UUMMAASSKK,
and SSIITTEE CCHHMMOODD.
++oo Filenames must start with an alpha-numeric character, and consist of
alpha-numeric characters or any of the following: + (plus), - (mi-
nus), = (equal), _ (underscore), . (period), and , (comma).
FFIILLEESS
/etc/ftpusers Access list for users.
/etc/ftpchroot List of normal users who should be chroot'd.
/etc/ftpwelcome Welcome notice.
/etc/motd Welcome notice after login.
/etc/nologin Displayed and access refused.
~/.klogin Login access for Kerberos.

The server must run as the super-user to create sockets with privileged
port numbers. It maintains an effective user id of the logged in user,
reverting to the super-user only when binding addresses to sockets. The
possible security holes have been extensively scrutinized, but are possi-
bly incomplete.

_/_e_t_c_/_f_t_p_u_s_e_r_s - FTP access list file
DDEESSCCRRIIPPTTIIOONN
_/_e_t_c_/_f_t_p_u_s_e_r_s contains a list of users that should be allowed or denied
FTP access. Each line contains a user, optionally followed by ``allow''
(anything but ``allow'' is ignored). The semi-user ``*'' matches any us-
er. Users that has an explicit ``allow'', or that does not match any
line, are allowed access. Anyone else is denied access.
Note that this is compatible with the old format, where this file con-
tained a list of users that should be denied access.
EEXXAAMMPPLLEESS
This will deny anyone but ``foo'' and ``bar'' to use FTP:
foo allow
bar allow

DDEESSCCRRIIPPTTIIOONN
The kkff program forwards tickets to a remove host through an authenticated
and encrypted stream. Options supported are:
--pp _p_o_r_t, ----ppoorrtt=_p_o_r_t
port to connect to
--ll _l_o_g_i_n, ----llooggiinn=_l_o_g_i_n
remote login name

forward forwardable credentials
--GG, ----nnoo--ffoorrwwaarrddaabbllee
do not forward forwardable credentials
--hh, ----hheellpp
----vveerrssiioonn
kkff is useful when you do not want to enter your password on a remote host
but want to have your tickets one for example afs.
In order for kkff to work you will need to acquire your initial ticket with
forwardable flag, ie kkiinniitt ----ffoorrwwaarrddaabbllee.
tteellnneett is able to forward ticket by itself.

2001-01-17 Johan Danielsson <joda@pdc.kth.se>
* common.c: don't write to string constants
2000-12-31 Assar Westerlund <assar@sics.se>
* krb5.c (krb5_make_context): handle krb5_init_context failure
consistently
2000-10-08 Assar Westerlund <assar@sics.se>
* kxd.c (doit_passive): check that fds are not too large to select
on
* kx.c (doit_active): check that fds are not too large to select
on
* krb5.c (krb5_copy_encrypted): check that fds are not too large
to select on
* krb4.c (krb4_copy_encrypted): check that fds are not too large
to select on
2000-06-10 Assar Westerlund <assar@sics.se>
* Makefile.in: use INSTALL_SCRIPT for installing rxterm, rxtelnet,
tenletxr
2000-04-19 Assar Westerlund <assar@sics.se>
* common.c: try hostname uncanonified if getaddrinfo() fails
2000-02-06 Assar Westerlund <assar@sics.se>
* kx.h: remove old prorotypes
2000-01-08 Assar Westerlund <assar@sics.se>
* common.c (match_local_auth): handle ai_canonname being set in
any of the addresses returnedby getaddrinfo. glibc apparently
returns the reverse lookup of every address in ai_canonname.
1999-12-28 Assar Westerlund <assar@sics.se>
* kxd.c (main): call krb5_getportbyname with the default in
host-byte-order
1999-12-17 Assar Westerlund <assar@sics.se>
* common.c (match_local_auth): remove extra brace. spotted by
Jakob Schlyter <jakob@cdg.chalmers.se>
1999-12-16 Assar Westerlund <assar@sics.se>
* common.c (match_local_auth): handle ai_canonname not being set
1999-12-06 Assar Westerlund <assar@sics.se>
* krb4.c (krb4_authenticate): the NAT address might not be the one
for the relevant realm, try anyway.
* kxd.c (recv_conn): type correctness
* kx.c (connect_host): typo
1999-12-05 Assar Westerlund <assar@sics.se>
* common.c (INADDR_LOOPBACK): remove. now in roken.
* kxd.c (recv_conn): use getnameinfo_verified
* kxd.c (recv_conn): replace inaddr2str with getnameinfo
1999-12-04 Assar Westerlund <assar@sics.se>
* kx.c (connect_host): use getaddrinfo
* common.c (find_auth_cookie, match_local_auth): re-write to use
getaddrinfo
1999-11-27 Assar Westerlund <assar@sics.se>
* kxd.c (recv_conn): better errors when getting unrecognized data
1999-11-25 Assar Westerlund <assar@sics.se>
* krb4.c (krb4_authenticate): obtain the `local' address when
doing NAT. also turn on passive mode. From <thn@stacken.kth.se>
1999-11-18 Assar Westerlund <assar@sics.se>
* krb5.c (krb5_destroy): free the correct part of the context
1999-11-02 Assar Westerlund <assar@sics.se>
* kx.c (main): redo the v4/v5 selection for consistency. -4 ->
try only v4 -5 -> try only v5 none, -45 -> try v5, v4
1999-10-10 Assar Westerlund <assar@sics.se>
* Makefile.am (CLEANFILES): add generated files so that they get
cleaned away
1999-09-29 Assar Westerlund <assar@sics.se>
* common.c (match_local_auth): only look for FamilyLocal (and
FamilyWild) cookies. This will not work when we start talking tcp
to the local X-server but `connect_local_xsocket' and the rest of
the code doesn't handle it anyway and the old code could (and did)
pick up the wrong cookie sometimes. If we have to match
FamilyInternet cookies, the search order has to be changed anyway
1999-09-02 Assar Westerlund <assar@sics.se>
* kxd.c (childhandler): watch for child `wait_on_pid' to die.
(recv_conn): set `wait_on_pid' instead of looping on waitpid here
also. This should solve the problem of kxd looping which was
caused by the signal handler getting invoked before this waitpid
and reaping the child leaving this poor loop without any child
1999-08-19 Assar Westerlund <assar@sics.se>
* kxd.c (recv_conn): give better error message
(doit_active): don't die if fork gives EAGAIN
1999-08-19 Johan Danielsson <joda@pdc.kth.se>
* kxd.c (recv_conn): call setjob on crays;
(doit_passive): if fork fails with EAGAIN, don't shutdown, just close
the connection re-implement `-t' flag
1999-07-12 Assar Westerlund <assar@sics.se>
* Makefile.am: handle not building X programs
1999-06-23 Assar Westerlund <assar@sics.se>
* kx.c: conditionalize krb_enable_debug
1999-06-20 Assar Westerlund <assar@sics.se>
* kxd.c (main): hopefully do inetd confusion right
1999-06-15 Assar Westerlund <assar@sics.se>
* krb4.c (krb4_authenticate): get rid of a warning
* kx.h: const-pollution
* kx.c: use get_default_username and resulting const pollution
* context.c (context_set): const pollution
1999-05-22 Assar Westerlund <assar@sics.se>
* kxd.c (recv_conn): fix syslog messages
(main): fix inetd_flag thinko
1999-05-21 Assar Westerlund <assar@sics.se>
* kx.c (main): don't byte-swap the argument to krb5_getportbyname
* kx.c (main): try to use $USERNAME
1999-05-10 Assar Westerlund <assar@sics.se>
* Makefile.in (SOURCES*): update sources list
* kx.c (main): forgot to conditionalize some KRB5 code
* kxd.c (main): use getarg
(*): handle v4 and/or v5
* kx.h: update
* kx.c (main): use getarg.
(*): handle v4 and/or v5
* common.c (do_enccopy, copy_encrypted): remove use
net_{read,write} instead of krb_net_{read,write}
(krb_get_int, krb_put_int): include fallback of these for when we
compile without krb4
* Makefile.am (*_SOURCES): remove encdata, add krb[45].c,
context.c
(LDADD): add krb5
* krb4.c, krb5.c, context.c: new files
1999-05-08 Assar Westerlund <assar@sics.se>
* kxd.c (doit_passive): handle error code from
create_and_write_cookie
* kx.c (doit_active): handle error code from
create_and_write_cookie
* common.c (create_and_write_cookie): try to return better (and
correct) errors. Based on a patch from Love <lha@e.kth.se>

(match_local_auth): new function
(find_auth_cookie): new function
(replace_cookie): don't just take the first auth cookie. based on
patch from Ake Sandgren <ake@@cs.umu.se>

.\"
.Dd September 27, 1996
.Dt KX 1
.Os KTH-KRB
.Sh NAME
.Nm kx
.Nd
securely forward X conections
.Sh SYNOPSIS
.Ar kx
.Op Fl l Ar username
.Op Fl k
.Op Fl d
.Op Fl t
.Op Fl p Ar port
.Op Fl P
.Ar host
.Sh DESCRIPTION
The
.Nm
program forwards a X connection from a remote client to a local screen
through an authenticated and encrypted stream. Options supported by
.Nm kx :
.Bl -tag -width Ds
.It Fl l
Log in on remote the host as user
.Ar username .
.It Fl k
Do not enable keep-alives on the TCP connections.
.It Fl d
Do not fork. This is mainly useful for debugging.
.It Fl t
Listen not only on a UNIX-domain socket but on a TCP socket as well.
.It Fl p
Use the port
.Ar port .
.It Fl P
Force passive mode.
.El
.Pp
This program is used by
.Nm rxtelnet
and
.Nm rxterm
and you should not need to run it directly.
.Pp
It connects to a
.Nm kxd
on the host
.Ar host
and then will relay the traffic from the remote X clients to the local
server. When started, it prints the display and Xauthority-file to be
used on host
.Ar host
and then goes to the background, waiting for connections from the
remote
.Nm kxd.
.Sh SEE ALSO
.Xr rxtelnet 1 ,
.Xr rxterm 1 ,
.Xr kxd 8

kkxx - securely forward X conections
SSYYNNOOPPSSIISS
_k_x [--ll _u_s_e_r_n_a_m_e] [--kk] [--dd] [--tt] [--pp _p_o_r_t] [--PP] _h_o_s_t
DDEESSCCRRIIPPTTIIOONN
The kkxx program forwards a X connection from a remote client to a local
screen through an authenticated and encrypted stream. Options supported
by kkxx:
--ll Log in on remote the host as user _u_s_e_r_n_a_m_e.
--kk Do not enable keep-alives on the TCP connections.
--dd Do not fork. This is mainly useful for debugging.
--tt Listen not only on a UNIX-domain socket but on a TCP socket as
well.
--pp Use the port _p_o_r_t.
--PP Force passive mode.
This program is used by rrxxtteellnneett and rrxxtteerrmm and you should not need to
run it directly.
It connects to a kkxxdd on the host _h_o_s_t and then will relay the traffic
from the remote X clients to the local server. When started, it prints
the display and Xauthority-file to be used on host _h_o_s_t and then goes to
the background, waiting for connections from the remote kkxxdd..

TCP. Normally
.Nm kxd
will only listen for X connections on a UNIX socket, but some machines
(for example, Cray) have X libraries that are not able to use UNIX
sockets and thus you need to use TCP to talk to the pseudo-xserver
created by
.Nm kxd.
This option decreases the security significantly and should only be
used when it is necessary and you have considered the consequences of
doing so.
.It Fl i
Interactive. Do not expect to be started by
.Nm inetd,
but allocate and listen to the socket yourself. Handy for testing
and debugging.
.It Fl p
Port. Listen on the port
.Ar port .
Only usable with

kkxxdd - securely forward X conections
SSYYNNOOPPSSIISS
_k_x_d [--tt] [--ii] [--pp _p_o_r_t]
DDEESSCCRRIIPPTTIIOONN
This is the daemon for kkxx.
Options supported by kkxxdd:
--tt TCP. Normally kkxxdd will only listen for X connections on a UNIX
socket, but some machines (for example, Cray) have X libraries
that are not able to use UNIX sockets and thus you need to use
TCP to talk to the pseudo-xserver created by kkxxdd.. This option de-
creases the security significantly and should only be used when
it is necessary and you have considered the consequences of doing
so.
--ii Interactive. Do not expect to be started by iinneettdd,, but allocate
and listen to the socket yourself. Handy for testing and debug-
ging.
--pp Port. Listen on the port _p_o_r_t. Only usable with --ii.

.Sh DESCRIPTION
The
.Nm
program starts a
.Nm xterm
window with a telnet to host
.Ar host .
From this window you will also be able to run X clients that will be
able to connect securily to your X server. If
.Ar port
is given, that port will be used instead of the default.
.Pp
The supported options are:
.Bl -tag -width Ds
.It Fl l
Log in on the remote host as user
.Ar username
.It Fl k
Disables keep-alives
.It Fl t
Send
.Ar telnet_args
as arguments to
.Nm telnet
.It Fl x
Send
.Ar xterm_args
as arguments to
.Nm xterm
.It Fl w
Use
.Ar term_emulator
instead of xterm.
.It Fl n
Do not start any terminal emulator.

.Sh EXAMPLE
To login from host
.Va foo
(where your display is)
to host
.Va bar ,
you might do the following.
.Bl -enum

The rrxxtteellnneett program starts a xxtteerrmm window with a telnet to host _h_o_s_t.
From this window you will also be able to run X clients that will be able
to connect securily to your X server. If _p_o_r_t is given, that port will be
used instead of the default.
The supported options are:
--ll Log in on the remote host as user _u_s_e_r_n_a_m_e
--kk Disables keep-alives
--tt Send _t_e_l_n_e_t___a_r_g_s as arguments to tteellnneett
--xx Send _x_t_e_r_m___a_r_g_s as arguments to xxtteerrmm
--ww Use _t_e_r_m___e_m_u_l_a_t_o_r instead of xterm.
--nn Do not start any terminal emulator.
EEXXAAMMPPLLEE
To login from host _f_o_o (where your display is) to host _b_a_r, you might do
the following.
1. On foo: rrxxtteellnneett _b_a_r
2. You will get a new window with a tteellnneett to _b_a_r. In this window you
will be able to start X clients.

.Sh NAME
.Nm otp
.Nd
manages one-time passwords
.Sh SYNOPSIS
.Nm otp
.Op Fl dhlor
.Op Fl f Ar algorithm
.Op Fl u Ar user
.Ar sequence-number
.Ar seed
.Sh DESCRIPTION
The
.Nm
program initializes and updates your current series of one-time
passwords (OTPs).
.Pp
Use this to set a new series of one-time passwords. Only perform this
on the console or over an encrypted link as you will have to supply
your pass-phrase. The other two parameters are
.Ar sequence-number
and
.Ar seed .
.Pp
Options are:
.Bl -tag -width Ds
.It Fl d
To delete a one-time password.
.It Fl f
Choose a different
.Ar algorithm
from the default md5. Pick any of: md4, md5, and sha.
.It Fl h
For getting a help message.
.It Fl l
List the current table of one-time passwords.
.It Fl o
To open (unlock) the otp-entry for a user.
.It Fl r
To renew a one-time password series. This operation can be performed
over an potentially eavesdropped link because you do not supply the
pass-phrase. First you need to supply the current one-time password
and then the new one corresponding to the supplied
.Ar sequence-number
and
.Ar seed .
.It Fl u
To choose a different
.Ar user
to set one-time passwords for. This only works when running
.Nm
as root.

oottpp - manages one-time passwords
SSYYNNOOPPSSIISS
oottpp [--ddhhlloorr] [--ff _a_l_g_o_r_i_t_h_m] [--uu _u_s_e_r] _s_e_q_u_e_n_c_e_-_n_u_m_b_e_r _s_e_e_d
DDEESSCCRRIIPPTTIIOONN
The oottpp program initializes and updates your current series of one-time
passwords (OTPs).
Use this to set a new series of one-time passwords. Only perform this on
the console or over an encrypted link as you will have to supply your
pass-phrase. The other two parameters are _s_e_q_u_e_n_c_e_-_n_u_m_b_e_r and _s_e_e_d.
Options are:
--dd To delete a one-time password.
--ff Choose a different _a_l_g_o_r_i_t_h_m from the default md5. Pick any of:
md4, md5, and sha.
--hh For getting a help message.
--ll List the current table of one-time passwords.
--oo To open (unlock) the otp-entry for a user.
--rr To renew a one-time password series. This operation can be per-
formed over an potentially eavesdropped link because you do not
supply the pass-phrase. First you need to supply the current
one-time password and then the new one corresponding to the sup-
plied _s_e_q_u_e_n_c_e_-_n_u_m_b_e_r and _s_e_e_d.
--uu To choose a different _u_s_e_r to set one-time passwords for. This
only works when running oottpp as root.

.Op Fl h
.Op Fl f Ar algorithm
.Ar sequence-number
.Ar seed
.Sh DESCRIPTION
The
.Nm
program prints lists of OTPs.
.Pp
Use this to print out a series of one-time passwords. You will have
to supply the
.Ar sequence number
and the
.Ar seed
as arguments and then the program will prompt you for your pass-phrase.
.Pp
There are several different print formats. The default is to print
each password with six short english words.
.Pp
Options are:
.Bl -tag -width Ds
.It Fl e
Print the passwords in ``extended'' format. In this format a prefix
that says ``hex:'' or ``word:'' is included.
.It Fl f
To choose a different

to manage electronic mail for Macintosh and MS-DOS computers. The
server was developed at the University of California at Berkeley and
conforms fully to the specifications in RFC 1081[2] and RFC 1082[3].
The Berkeley server also has extensions to send electronic mail on
behalf of a client.
This guide explains how to install the POP server on your Unix
computer. It assumes that you are not only familiar with Unix but also
capable of performing Unix system administration.
How to Obtain the Server
The POP server is available via anonymous ftp from ftp.CC.Berkeley.EDU
(128.32.136.9, 128.32.206.12). It is in two files in the pub directory:
a compressed tar file popper-version.tar.Z and a Macintosh StuffIt archive
in BinHex format called MacPOP.sit.hqx.
Contents of the Distribution
The distribution contains the following:
+ All of the C source necessary to create the server program.
+ A visual representation of how the POP system works.
+ Reprints of RFC 1081 and RFC 1082.
+ A HyperCard stack POP client implementation using MacTCP.
+ A man page for the popper daemon.
+ This guide.
Compatibility
The Berkeley POP server has been successfully tested on the following
Unix operating systems:
+ Berkeley Systems Distribution 4.3
+ Sun Microsystems Operating System versions 3.5 and 4.0
+ Ultrix version 2.3
The following POP clients operate correctly with the Berkeley POP server:
+ The Berkeley HyperMail HyperCard stack for the Apple Macintosh
(distributed with the server).
+ The Stanford University Macintosh Internet Protocol MacMH program.
+ The Stanford University Personal Computer Internet Protocol MH
program.
+ The mh version 6.0 programs for Unix.
Support
The Berkeley POP server is not officially supported and is without any
warranty, explicit or implied. However, we are interested in your
experiences using the server. Bugs, comments and suggestions should be
sent electronically to netinfo@garnet.Berkeley.EDU.
Operational Characteristics
The POP Transaction Cycle
The Berkeley POP server is a single program (called popper) that is
launched by inetd when it gets a service request on the POP TCP port.
(The official port number specified in RFC 1081 for POP version 3 is
port 110. However, some POP3 clients attempt to contact the server at
port 109, the POP version 2 port. Unless you are running both POP2 and
POP3 servers, you can simply define both ports for use by the POP3
server. This is explained in the installation instructions later on.)
The popper program initializes and verifies that the peer IP address is
registered in the local domain, logging a warning message when a
connection is made to a client whose IP address does not have a
canonical name. For systems using BSD 4.3 bind, it also checks to see
if a cannonical name lookup for the client returns the same peer IP
address, logging a warning message if it does not. The the server
enters the authorization state, during which the client must correctly
identify itself by providing a valid Unix userid and password on the
server's host machine. No other exchanges are allowed during this
state (other than a request to quit.) If authentication fails, a
warning message is logged and the session ends. Once the user is
identified, popper changes its user and group ids to match that of the
user and enters the transaction state. The server makes a temporary
copy of the user's maildrop (ordinarily in /usr/spool/mail) which is
used for all subsequent transactions. These include the bulk of POP
commands to retrieve mail, delete mail, undelete mail, and so forth. A
Berkeley extension also allows the user to submit a mail parcel to the
server who mails it using the sendmail program (this extension is
supported in the HyperMail client distributed with the server). When
the client quits, the server enters the final update state during which
the network connection is terminated and the user's maildrop is updated
with the (possibly) modified temporary maildrop.
Logging
The POP server uses syslog to keep a record of its activities. On
systems with BSD 4.3 syslogging, the server logs (by default) to the
"local0" facility at priority "notice" for all messages except
debugging which is logged at priority "debug". The default log file is
/usr/spool/mqueue/POPlog. These can be changed, if desired. On
systems with 4.2 syslogging all messages are logged to the local log
file, usually /usr/spool/mqueue/syslog.
Problems
If the filesystem which holds the /usr/spool/mail fills up users will
experience difficulties. The filesystem must have enough space to hold
(approximately) two copies of the largest mail box. Popper (v1.81 and
above) is designed to be robust in the face of this problem, but you may
end up with a situation where some of the user's mail is in
/usr/spool/mail/.userid.pop
and some of the mail is in
/usr/spool/mail/userid
If this happens the System Administrator should clear enough disk space
so that the filesystem has at least as much free disk as both mailboxes
hold and probably a little more. Then the user should initiate a POP
session, and do nothing but quit. If the POP session ends without an
error the user can then use POP or another mail program to clean up his/her
mailbox.
Alternatively, the System Administrator can combine the two files (but
popper will do this for you if there is enough disk space).
Debugging
The popper program will log debugging information when the -d parameter
is specified after its invocation in the inetd.conf file. Care should
be exercised in using this option since it generates considerable
output in the syslog file. Alternatively, the "-t <file-name>" option
will place debugging information into file "<file-name>" using fprintf
instead of syslog. (To enable debugging, you must edit the Makefile
to add -DDEBUG to the compiler options.)
For SunOS version 3.5, the popper program is launched by inetd from
/etc/servers. This file does not allow you to specify command line
arguments. Therefore, if you want to enable debugging, you can specify
a shell script in /etc/servers to be launched instead of popper and in
this script call popper with the desired arguments.
Installation
1. Examine this file for the latest information, warnings, etc.
2. Check the Makefile for conformity with your system.
3. Issue the make command in the directory containing the popper
source.
4. Issue the make install command in the directory containing the
popper source to copy the program to /usr/etc.
5. Enable syslogging:
+ For systems with 4.3 syslogging:
Add the following line to the /etc/syslog.conf file:
local0.notice;local0.debug /usr/spool/mqueue/POPlog
Create the empty file /usr/spool/mqueue/POPlog.
Kill and restart the syslogd daemon.
+ For systems with 4.2 syslogging:
Be sure that you are logging messages of priority 7 and higher.
For example:
7/usr/spool/mqueue/syslog
9/dev/null
6. Update /etc/services:
Add the following line to the /etc/services file:
pop 110/tcp
Note: This is the official port number for version 3 of the
Post Office Protocol as defined in RFC 1081. However, some
POP3 clients use port 109, the port number for the previous
version (2) of POP. Therefore you may also want to add the
following line to the /etc/services file:
pop2 109/tcp
For Sun systems running yp, also do the following:
+ Change to the /var/yp directory.
+ Issue the make services command.
7. Update the inetd daemon configuration. Include the second line ONLY if you
are running the server at both ports.
+ On BSD 4.3 and SunOS 4.0 systems, add the following line to the
/etc/inetd.conf file:
pop stream tcp nowait root /usr/etc/popper popper
pop2 stream tcp nowait root /usr/etc/popper popper
+ On Ultrix systems, add the following line to the
/etc/inetd.conf file:
pop stream tcp nowait /usr/etc/popper popper
pop2 stream tcp nowait /usr/etc/popper popper
+ On SunOS 3.5 systems, add the following line to the
/etc/servers file:
pop tcp /usr/etc/popper
pop2 tcp /usr/etc/popper
Kill and restart the inetd daemon.
You can confirm that the POP server is running on Unix by telneting to
port 110 (or 109 if you set it up that way). For example:
%telnet myhost 110
Trying...
Connected to myhost.berkeley.edu.
Escape character is '^]'.
+OK UCB Pop server (version 1.6) at myhost starting.
quit
Connection closed by foreign host.
Release Notes
1.83 Make sure that everything we do as root is non-destructive.
1.82 Make the /usr/spool/mail/.userid.pop file owned by the user rather
than owned by root.
1.81 There were two versions of 1.7 floating around, 1.7b4 and 1.7b5.
The difference is that 1.7b5 attempted to save disk space on
/usr/spool/mail by deleting the users permanent maildrop after
making the temporary copy. Unfortunately, if compiled with
-DDEBUG, this version could easily wipe out a users' mail file.
This is now fixed.
This version also fixes a security hole for systems that have
/usr/spool/mail writeable by all users.
With this version we go to all new SCCS IDs for all files. This
is unfortunate, and we hope it is not too much of a problem.
Thanks to Steve Dorner of UIUC for pointing out the major problem.
1.7 Extensive re-write of the maildrop processing code contributed by
Viktor Dukhovni <viktor@math.princeton.edu> that greatly reduces the
possibility that the maildrop can be corrupted as the result of
simultaneous access by two or more processes.
Added "pop_dropcopy" module to create a temporary maildrop from
the existing, standard maildrop as root before the setuid and
setgid for the user is done. This allows the temporary maildrop
to be created in a mail spool area that is not world read-writable.
This version does *not* send the sendmail "From " delimiter line
in response to a TOP or RETR command.
Encased all debugging code in #ifdef DEBUG constructs. This code can
be included by specifying the DEGUG compiler flag. Note: You still
need to use the -d or -t option to obtain debugging output.
1.6 Corrects a bug that causes the server to crash on SunOS
4.0 systems.
Uses varargs and vsprintf (if available) in pop_log and
pop_msg. This is enabled by the "HAVE_VSPRINTF"
compiler flag.
For systems with BSD 4.3 bind, performs a cannonical
name lookup and searches the returned address(es) for
the client's address, logging a warning message if it
is not located. This is enabled by the "BIND43"
comiler flag.
Removed all the includes from popper.h and distributed
them throughout the porgrams files, as needed.
Reformatted the source to convert tabs to spaces and
shorten lines for display on 80-column terminals.
1.5 Creates the temporary maildrop with mode "600" and
immediately unlinks it.
Uses client's IP address in lieu of a canonical name if
the latter cannot be obtained.
Added "-t <file-name>" option. The presence of this
option causes debugging output to be placed in the file
"file-name" using fprintf instead of the system log
file using syslog.
Corrected maildrop parsing problem.
1.4 Copies user's mail into a temporary maildrop on which
all subsequent activity is performed.
Added "pop_log" function and replaced "syslog" calls
throughout the code with it.
1.3 Corrected updating of Status: header line.
Added strncasecmp for systems that do not have one.
Used strncasecmp in all appropriate places. This is
enabled by the STRNCASECMP compiler flag.
1.2 Support for version 4.2 syslogging added. This is
enabled by the SYSLOG42 compiler flag.
1.1 Several bugs fixed.
1.0 Original version.
Limitations
+ The POP server copies the user's entire maildrop to /tmp and
then operates on that copy. If the maildrop is particularly
large, or inadequate space is available in /tmp, then the
server will refuse to continue and terminate the connection.
+ Simultaneous modification of a single maildrop can result in
confusing results. For example, manipulating messages in a
maildrop using the Unix /usr/ucb/mail command while a copy of
it is being processed by the POP server can cause the changes
made by one program to be lost when the other terminates. This
problem is being worked on and will be fixed in a later
release.

This kerberized popper was based on popper-1.831beta
which was later announced as "offical" and not beta.
This program is able to talk both the pop3 and the kpop3 protocol.
Please note that the server principal is pop.hostname and not
rcmd.hostname. I.e an additional entry is needed in your mailhub's
/etc/srvtab. Use ksrvutil to add the extra prinicpal.
The server is usually started from inetd and there is already an entry
for that in inetd.conf.changes.
