Par défaut sshd daemon crashing
My sshd daemon is crashing on a Solaris 9 SUN box.

/usr/local/bin/ssh -Version shows
OpenSSH_4.2p1, OpenSSL 0.9.8a 11 Oct 2005

The output of sshd -d from startup to crash is enclosed below.

Please advise if you have seen this. We have hundreds of other
systems and don't have this issue on any of them.

Thanks ahead,

Stuart

What crash? There is no crash. It says that you closed it down.

Remember that ssh -d only runs ONCE. It exits when that one first session
exits.

>/usr/local/bin/ssh -Version shows

What crash? You will need to give us what you feel is evidence that sshd
crashed.
