SSH Weirdness
About a week ago our ssh sessions stopped enforcing the inactivity time out. I thought it was weird, but I didn't have a chance to look into it. Then on Wednesday night the system had a catastrophic failure and we had to reboot it from the ILO. HP said the error messages they were seeing were consistent with an ssh failure and recommended upgrading to version 8.
Does this sound familiar to anybody?
Thanks in advance,
Margaret

Re: SSH Weirdness
The details no. The overall situation yes. The system had troubles, showed signs, asked for attention and did not get it.
Please post exact error messages.
seh is constantly being updated due to critical flaws and security holes. Updating it is a very good idea.

Re: SSH Weirdness
The only problem is, I'm guessing that since this is the root volume group, you can't unmount anything to try this and I can't think of any way to cause a full fsck on next boot.

Re: SSH Weirdness
Does anybody have any insight into why the inactive time out period just went away?
I'm not sure where to check if that's still enabled.

Re: SSH Weirdness
I'm leaning toward there being two issues here; one being the SSH stuff and the other being the crash.
How was the timeout set up before? Was it truly a function of SSH, or was it done at the shell level (by setting TMOUT or something)?
