[DLC] SSH What?

Tue Jan 22 15:57:42 CST 2008

Okay guys,

Totally strange problem.  I have 9 RedHat 5 AS boxes at one of my
clients.  On one of the boxes, ssh for any user does not work.  I
built the boxes identical using a kickstart CD with user accounts
'orc' and 'goblin'.  I'm using PAM authentication and passwords.
Strangley enough the sshd_config files are all identical as well as
the /etc/pam.d/sshd files.  I also check tty permissoins and even
tried setting up another user.  I've included the output of the ssh
-vv orc at matorc7 as well as my secure.log file.

Any help is appreciated!
-Scott
