SSH Hanging on 11503

cantorb — Tue, 11 Jan 2005 00:57:45 GMT

Today I entered my keys for SSH and am experiencing some issues. If I do not keep my session active (constantly issuing commands) for more than approx. 45sec my session will lock up. I can then start another session but the previous session(s) remain active. I can't seem to determine how to kill these.

Having said that here are my questions:

How do I prevent these sessions from hanging?

How do I kill the hung sessions?

this kind of issue should not happen.

What version do you use ?

The only valid way to kill sessions is to reboot the CSS.

There is a bug currently open where SSH session are not timing out properly making the box eventually unreachable.

Regards,

Gilles.

I'm glad to know that this is not something that I would see under normal circumstances. Here is the output of the sho ver

qw-css-1# sho ver

Flash (Locked): 07.30.1.06

Do you have any more information on this bug you speak of...I'll research it on my end but if you have it handy I'd appreciate a link.

Also, here is the output from the sho sshd config

qw-css-1# sho sshd config
