Description Dax Kelson 2005-09-04 16:21:26 UTC

Description of problem:

One of the new features of MIT Kerberos v1.4 is the ability to *require* a
kerberos encrypted telnet sessions. Previously this was not possible with ktelnetd.

Please enable this by default in the xinetd config file for ktelnetd.

To /etc/xinetd.d/krb5-telnet

add

server_args     = -e

This will bring the default Fedora config of ktelnetd in sync with kshd.

Comment 1 Dax Kelson 2005-09-04 17:05:09 UTC

Thinking about this more, I have a different proposal that extends how klogin is
already configured.

Today there are two xinetd config files for klogind.

/etc/xinet.d/klogin
/etc/xinet.d/eklogin  (requires encryption with the -e switch)

This way you can chkconfig on which ever one you want. A reasonable and sound
approach.

I propose this same scheme be extended to ktelnetd and kshell. So there exists:

/etc/xinet.d/krb5-telnet
/etc/xinet.d/ekrb5-telnet (requires encryption)
/etc/xinet.d/kshell
/etc/xinet.d/ekshell (requires encryption)

That sounds good to me.  Adding to 1.4.2-3.

Comment 3 Nalin Dahyabhai 2005-09-06 15:56:39 UTC

Hrm.  I don't think I'm going to get behind changing the "kshell" service from
encrypted to unencrypted though.  That sounds like a nasty surprise, no matter
how well documented it could be.
