Logging out of Secure Shell (SSH)

[Christina Martin]

When a user logs out of a session of Secure Shell, it appears as if they log completely out. When they try to log back in, the system tells them they are still connected. When we attempt to kill the process, it tells us that the process is no longer running.

Does anyone know why this is happening and what we can do to correct it?

Thanks in advance.

This sounds like you are either running a very outdated version of sshd or you are behind on the patches.

what does the output of command:

what /opt/ssh/PA-RISC2.0/sbin/sshd

say ? Also, could you please post the contents of file:

/opt/ssh/etc/sshd_config

Christina,
Please download the newer ssh package and install it and that should resolve the issue

You can check your version by doing
#swlist -l product | grep -i secure
mine shows up as
Secure_Shell A.03.81.002 HP-UX Secure Shell

and it works fine

thanks

When I run the swlist command, the version is:

Secure_Shell A.04.00.000 HP-UX Secure Shell
(which I believe is the most current). Our problem may be the patches.

When I run the what /opt/ssh/PA-RISC2.0/sbin/sshd, I get quite a bit of output. Is there something in particular that you are looking for?

The contents of /opt/ssh/etc/sshd_config is as follows:
