Description Paul Schmehl 2003-01-22 23:19:49 UTC

Description of problem:
This isn't a redhat-config-network bug (at least I don't think it is), but I
couldn't find anything more appropriate to class it as.

After the box is up for a while, hostname resolution fails completely.  The only
way I've found to restore it is to restart networking (/etc/rc.d/init.d/network
restart).

I wasn't running nscd, so I've enabled that to see if it will resolve the problem.

I haven't been able to determine if this happens after a certain time frame or
after running a specific application, but it fails consistently, at least on a
daily basis.

Typically evolution will begin to complain of being unable to ping an imap host.
 This will go on for while, and then evolution will completely lose its
connection to the mail server.  I also can't use any network utilities (ping,
traceroute, dig, nmap, etc.)

If an strace will help, I can provide one.

Comment 1 Harald Hoyer 2003-01-23 10:15:39 UTC
dhcp?

Comment 2 Harald Hoyer 2003-01-23 10:16:38 UTC
please provide /etc/sysconfig/network-scripts/ifcfg-eth0

some /var/log/messages of interest?



Comment 3 Paul Schmehl 2003-01-23 18:22:23 UTC
To answer your questions:

I using dhcp, but my IP address is fixed.  IOW, I always get the same IP when
the lease is renewed.

cat /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
BOOTPROTO=dhcp
ONBOOT=yes

egrep '(error|warn|fatal)' /var/log/messages
