I'm using SuSE 8.1 as server.

All was working properly this noon.
Sometime this afternoon attempted logins from
remote or loop back from console cause hang.

I found nothing helpful in the logs but I did run
sshd with -d -d -d startup.

I got the following log

1752: debug1: sshd version OpenSSH_3.4p1

I assume it must be a corrupt file someplace, but having no luck
finding
it.

I can ssh from the server to another server and
I can telnet to the server in questions.

Any suggestions appreciated.

PROBLEM-RESOLUTION
First, thanks for your thoughtful suggestions.

Research found that the server (with static address) did not have
current
dns addresses. We experienced ISP problems during the day,
which I admit I did not mention. Our speculation is that the ISP was
updating
its dns server farm and took the addresses referenced by this server
out
of service. They were current dns addresses several years ago. As
soon as we changed the server dns addresses to the current batch, the
problem was solved.

Regards...Dan.
