Solaris sun server keeps losing network connection

by william tevi » Tue, 04 Aug 1998 04:00:00

hello

i have a sun server running solaris 2.5.1 with latest patches
sendmail 8.8.8
bind 8.1
qpopper 2.2

i have noticed that periodically it loses tcp connection to the
whole network. its connected to a cisco catalyst 1900 but
some of the symptoms are that when you do a telnet to the server
it loses connection.

regards

william

1. Sun loses network connection

I have a Sun Ultra 60 that frequently loses its network connection for no
apparent reason and after some time connection comes back up again I
can't find any error messages in the usual places.
I've tried to diagnose the problem, set NIC to full-duplex, no
negotiation, checked DNS, hostname netmasks settings, but it didn't help.
How else can I diagnose the problem?

Thanks, any suggestions are appreciated.

Eugene.
