Connection Problems After Upgrade

[Dan D Niles]

I upgraded 5 servers yesterday from FreeBSD 7.0 p1 to p3.  Now I'm
having connection problems on them.  I see log entries like:

 Jul 15 11:24:27 hostname ntpd[49394]: sendto(192.168.0.1): Network is
unreachable
Jul 15 12:02:56 hostname ntpd[49394]: sendto(192.168.0.1): Network is
unreachable
Jul 15 13:28:17 hostname ntpd[49394]: sendto(192.168.0.1): Network is
unreachable
Jul 15 13:45:21 hostname ntpd[49394]: sendto(192.168.0.1): Network is
unreachable

If I leave an ssh session idle, I get:

Read from remote host hostname.more.net: Connection reset by peer

I didn't have any problems before upgrading to p3.  Any ideas?

Thanks,

Dan
