sshd error message

[Andrew Kaplan]

I have a user trying to connect to one of our machines (running 10.20) using ssh. When he tries to login he receives the following message:

AUTHENTICATION SUCCESSFUL
RECEIVED SIGNAL 11. (NO CORE)

Any ideas? Thanks.

Could you have him run a verbose connection attempt, i.e.. ssh -v and then post that output. Also, check to make sure that your protocols are the same, either 1 or 2.

Awaiting the info...

Andrew,
I looked up signal 11 in /usr/include/sys/signal.h. It is defined as a segmentation violation. You may want to see if there is anything in syslog about a segmentaion problem.

This may provide you the answer. Compare your kernel settings to what this thread talks about.

Craig, Here is the syslog.log file you had requested.

Andrew,
You definately have a protocol error. The protocol that your clients are using is different than the protocol the server is running. There may be more that just that, but I would say you also have a tooltalk problem as well based on all the rpc.ttdbserver errors you had in there. Is CDE working ok?

A ssh -v output would be helpful as well.

Hi Andrew,

There is one option StrictModes which is by default yes. sshd will not permit logins if the permissions on the corresponding home directory are world-writable. Try changing the permissions and see.

If possible, you can start sshd in debug mode with the command line option sshd -d and it will printout debug messages and you should be able to make out what is causing the problem.

FYI,
Sridhar

Craig,

There may be a configuration issue with the X environment. My reasoning behind this theory is the error message I received -

/usr/bin/X11/xauth: (argv):1: bad display name "2" in "list" command

Your thoughts?
