several new kerberos related libraries and applications to FreeBSD:
o kgetcred(1) allows one to manually get a ticket for a particular service.
o kf(1) securily forwards ticket to another host through an authenticated
and encrypted stream.
o kcc(1) is an umbrella program around klist(1), kswitch(1), kgetcred(1)
and other user kerberos operations. klist and kswitch are just symlinks
to kcc(1) now.
o kswitch(1) allows you to easily switch between kerberos credentials if
you're running KCM.
o hxtool(1) is a certificate management tool to use with PKINIT.
o string2key(1) maps a password into key.
o kdigest(8) is a userland tool to access the KDC's digest interface.
o kimpersonate(8) creates a "fake" ticket for a service.
We also now install manpages for some lirbaries that were not installed
before, libheimntlm and libhx509.
- The new HEIMDAL version no longer supports Kerberos 4. All users are
recommended to switch to Kerberos 5.
- Weak ciphers are now disabled by default. To enable DES support (used
by telnet(8)), use "allow_weak_crypto" option in krb5.conf.
- libtelnet, pam_ksu and pam_krb5 are now compiled with error on warnings
disabled due to the function they use (krb5_get_err_text(3)) being
deprecated. I plan to work on this next.
- Heimdal's KDC now require sqlite to operate. We use the bundled version
and install it as libheimsqlite. If some other FreeBSD components will
require it in the future we can rename it to libbsdsqlite and use for these
components as well.
- This is not a latest Heimdal version, the new one was released while I was
working on the update. I will update it to 1.5.2 soon, as it fixes some
important bugs and security issues.

|
|
.Sh SYNOPSIS
|
|
.Nm
|
|
.Op Fl aiklnvxPL
|
|
.Op Fl p Ar port
|
|
.Sh DESCRIPTION
|
|
.Nm
|
|
is the server for
|
|
the
|
|
.Xr rsh 1
|
|
program. It provides an authenticated remote command execution
|
|
service. Supported options are:
|
|
.Bl -tag -width Ds
|
|
.It Xo
|
|
.Fl n ,
|
|
.Fl Fl no-keepalive
|
|
.Xc
|
|
Disables keep-alive messages.
|
|
Keep-alives are packets sent at certain intervals to make sure that the
|
|
client is still there, even when it doesn't send any data.
|
|
.It Xo
|
|
.Fl k ,
|
|
.Fl Fl kerberos
|
|
.Xc
|
|
Assume that clients connecting to this server will use some form of
|
|
Kerberos authentication. See the
|
|
.Sx EXAMPLES
|
|
section for a sample
|
|
.Xr inetd.conf 5
|
|
configuration.
|
|
.It Xo
|
|
.Fl x ,
|
|
.Fl Fl encrypt
|
|
.Xc
|
|
For Kerberos 4 this means that the connections are encrypted. Kerberos
|
|
5 can negotiate encryption even without this option, but if it's
|
|
present
|
|
.Nm
|
|
will deny unencrypted connections. This option implies
|
|
.Fl k .
|
|
.\".It Xo
|
|
.\".Fl l ,
|
|
.\".Fl Fl no-rhosts
|
|
.\".Xc
|
|
.\"When using old port-based authentication, the user's
|
|
.\".Pa .rhosts
|
|
.\"files are normally checked. This option disables this.
|
|
.It Xo
|
|
.Fl v ,
|
|
.Fl Fl vacuous
|
|
.Xc
|
|
If the connecting client does not use any Kerberised authentication,
|
|
print a message that complains about this fact, and exit. This is
|
|
helpful if you want to move away from old port-based authentication.
|
|
.It Xo
|
|
.Fl P
|
|
.Xc
|
|
When using the AFS filesystem, users' authentication tokens are put in
|
|
something called a PAG (Process Authentication Group). Multiple
|
|
processes can share a PAG, but normally each login session has its own
|
|
PAG. This option disables the
|
|
.Fn setpag
|
|
call, so all tokens will be put in the default (uid-based) PAG, making
|
|
it possible to share tokens between sessions. This is only useful in
|
|
peculiar environments, such as some batch systems.
|
|
.It Xo
|
|
.Fl i ,
|
|
.Fl Fl no-inetd
|
|
.Xc
|
|
The
|
|
.Fl i
|
|
option will cause
|
|
.Nm
|
|
to create a socket, instead of assuming that its stdin came from
|
|
.Xr inetd 8 .
|
|
This is mostly useful for debugging.
|
|
.It Xo
|
|
.Fl p Ar port ,
|
|
.Fl Fl port= Ns Ar port
|
|
.Xc
|
|
Port to use with
|
|
.Fl i .
|
|
.It Xo
|
|
.Fl a
|
|
.Xc
|
|
This flag is for backwards compatibility only.
|
|
.It Xo
|
|
.Fl L
|
|
.Xc
|
|
This flag enables logging of connections to
|
|
.Xr syslogd 8 .
|
|
This option is always on in this implementation.

The following can be used to enable Kerberised rsh in
