(Including all changes for FreeBSD - importing the original eBones distribution would be too complex at this stage, since I don't have access to Piero's CVS.) (If you want to include eBones in your system, don't forget to include MAKE_EBONES in /etc/make.conf.) (This stuff is now also suppable from braae.ru.ac.za.) Bones originally from MIT SIPB. Original port to FreeBSD 1.x by Piero Serini. Moved to FreeBSD 2.0 by Doug Rabson and Geoff Rehmet. Nice bug fixes from Doug Rabson.

.SH DESCRIPTION
|
|
.I Rlogin
|
|
connects your terminal on the current local host system
|
|
.I lhost
|
|
to the remote host system
|
|
.I rhost.
|
|
.PP
|
|
The version built to use Kerberos authentication is very similar to the
|
|
standard Berkeley rlogin(1), except that instead of the \fIrhosts\fP
|
|
mechanism, it uses Kerberos authentication to determine the
|
|
authorization to use a remote account.
|
|
.PP
|
|
Each user may have a private authorization list in a file \&.klogin
|
|
in his login directory. Each line in this file should contain a
|
|
Kerberos principal name of the form
|
|
.IR principal.instance@realm .
|
|
If the originating user is authenticated to one of the principals named
|
|
in \&.klogin, access is granted to the account. The principal
|
|
\fIaccountname\fP.@\fIlocalrealm\fP is granted access if there is no
|
|
\&.klogin file.
|
|
Otherwise
|
|
a login and password will be prompted for on the remote machine as in
|
|
.IR login (1).
|
|
To avoid some security problems, the \&.klogin file must be owned by
|
|
the remote user.
|
|
.PP
|
|
If there is some problem in marshaling the Kerberos authentication
|
|
information, an error message is printed and the standard UCB rlogin is
|
|
executed in place of the Kerberos rlogin.
|
|
.PP
|
|
A line of the form ``~.'' disconnects from the remote host, where
|
|
``~'' is the escape character.
|
|
Similarly, the line ``~^Z'' (where ^Z, control-Z, is the suspend character)
|
|
will suspend the rlogin session.
|
|
Substitution of the delayed-suspend character (normally ^Y)
|
|
for the suspend character suspends the send portion of the rlogin,
|
|
but allows output from the remote system.
|
|
.PP
|
|
The remote terminal type is the same as your local
|
|
terminal type (as given in your environment TERM variable), unless the
|
|
.B \-t
|
|
option is specified (see below).
|
|
The terminal or window size is also copied to the remote system
|
|
if the server supports the option,
|
|
and changes in size are reflected as well.
|
|
.PP
|
|
All echoing takes place at the remote site, so that (except for
|
|
delays) the rlogin is transparent. Flow control via ^S and ^Q and
|
|
flushing of input and output on interrupts are handled properly.
|
|
.PP
|
|
The
|
|
.B \-8
|
|
option allows an eight-bit input data path at all times;
|
|
otherwise parity bits are stripped except when the remote side's
|
|
stop and start characters are other than ^S/^Q. Eight-bit mode is the default.
|
|
.PP
|
|
The
|
|
.B \-L
|
|
option allows the rlogin session to be run in litout mode.
|
|
.PP
|
|
The
|
|
.B \-e
|
|
option allows specification of a different escape character.
|
|
There is no space separating this option flag and the new escape
|
|
character.
|
|
.PP
|
|
The
|
|
.B \-c
|
|
option requires confirmation before disconnecting via ``~.''
|
|
.PP
|
|
The
|
|
.B \-a
|
|
option forces the remote machine to ask for a password by sending a null local
|
|
username. This option has no effect unless the standard UCB rlogin is
|
|
executed in place of the Kerberos rlogin (see above).
|
|
.PP
|
|
The
|
|
.B \-t
|
|
option replaces the terminal type passed to the remote host with
|
|
\fItermtype\fP.
|
|
.PP
|
|
The
|
|
.B \-n
|
|
option prevents suspension of rlogin via ``~^Z'' or ``~^Y''.
|
|
.PP
|
|
The
|
|
.B \-7
|
|
option forces seven-bit transmissions.
|
|
.PP
|
|
The
|
|
.B \-d
|
|
option turns on socket debugging (via \fIsetsockopt(2)\fR) on the TCP
|
|
sockets used for communication with the remote host.
|
|
.PP
|
|
The
|
|
.B \-noflow
|
|
option forces transmission of flow control characters (^S/^Q) to the
|
|
remote system.
|
|
.PP
|
|
The
|
|
.B \-k
|
|
option requests rlogin to obtain tickets for the remote host in realm
|
|
.I realm
|
|
instead of the remote host's realm as determined by
|
|
.IR krb_realmofhost (3).
|
|
.PP
|
|
The
|
|
.B \-x
|
|
option turns on DES encryption for all data passed via the
|
|
rlogin session. This significantly reduces response time and
|
|
significantly increases CPU utilization.
