Hello, This is perhaps a long shot, but anyway... I assume the reason you tried turning off DNS look-ups is that remote host cannot resolve the local hostname, or it can, but takes a relatively long time to do so. You might check and see if syslog has DNS look-ups enabled. It's been a while, but I think we had a similar problem and don't ask me why, but turning off DNS look-ups for syslog solved the problem. I can't believe that sshd would block waiting for syslog, but I suppose it could be true... -Andrew On Sat, 2006-05-20 at 17:26 +0400, Andrew Pantyukhin wrote: > I have a problem.
