Server doing some weird things, HELP!!

Phillip Popp — Tue, 17 Jul 2007 07:35:01 GMT

Hi,
I am running hp 10.2, Yester day my srever was doing some weird things. couldn't run sam, not even an ls would work. Rebooted, all worked fine till today. Now I can only seem to log into system with root. All other users report no shell when I try to do a su.

I think something is starting to physically go wrong with my hard drives. I thought about running fsck. Can this be run on a mounted file system. Will this repair or rewrite any bad files? I have 10 people at my cube asking what is wrong, please give me some guidence. i do not see any thing in the syslog that points to a problem, although admittitly, I don't really know where to look in the file or other log files for guidence. Please help!!

Thanks,

Phil

try running bdf and see if a file system is full. If you can try and post the output from syslog and dmesg.

Check your disc(s) with ioscan -fnC disk

No shell? Do ll /etc/passwd and check the date and timestamp in case someone has been messing about with the contents. Make sure the shell allocated to users is a valid one.

Hi,

also check user log in .dt - error.log, startlog, sessionlogs.

'a mounted file system' - mounted from where?

File system not full, only 80 some %. Passwd file seems ok.

Any idea what to do next?

Thanks,

A follow up to Mike's suggestion would be to run pwck. Also check to see if the shell binary that the users are using is actually in there. Maybe someone removed/renamed/deleted it. The syslog you attached looks fine.

Sorry Mark I called you Mike. How could I forget that after reading "Mark Syder (like the drink but spelt different)" so many times.

Hi,

this sems to be the log file of root (which works, right?).
Check .dt in the users home directories ...

I did an IO scan and it see all three disks, all three claimed, with paths.

Did not get any error messages?

Thanks,

Hi Phil

Could you also add your /etc/rc.log file?

In addition just to check that your /home folders are all local and not automounted. You are not running NIS perhaps?

What result do you get when you run bdf /home.

Also bdf without any parameters (I suspect it might hang though)

Run ioscan -fnC disk and see if there are any NO_HW or other errors.

What shell are the users using?

My feelings are there are either problems with the users home directories or with the shell which is usually in /usr/bin or /usr/local/bin but check /etc/passwd for its location.

"Sorry Mark I called you Mike. How could I forget that after reading "Mark Syder (like the drink but spelt different)" so many times."

That's quite all right, Mr Campfire ;-)

Phil - the final field in the /etc/passwd file tells you the user's shell. For root it should be /sbin/sh, for other users it may be different. Check the entry for a user who cannot log in and do ll /sbin/sh (or whatever shell it happens to be). The ll command should produce successful output.

hi Phil,

can you try to telnet on the server and create a new test user using SAM and see if the latter is able to login.

revert

kind regards

My users are using the k shell

Re: Server doing some weird things, HELP!!

Court Campbell — Tue, 17 Jul 2007 09:03:10 GMT

what happens if you

# ll /usr/bin/ksh

See if the binary is there. try running the shell as root and see if runs or possibly makes a core dump.

It does not like the || in front of the /usr/bin/ksh. Syntax error " || not expected"

With out it, it just returns back to the prompt, no out put messages?

Hi Phil

Use ls -l instead of ll
