Mike,
Thanks, I have already checked that and it is set without the nisplus.
Is there a way to force all nameserver queries to use TCP?
It looks like the problem is that the lookups are going out UDP. (from a
netstat -a) but the responses are not coming back. At least not with the
address that is being looked up. The address of the authoritative nameserver
is what gets returned. (from tehtereal).
If I issue a host www.google.com it times out. If I issue a host -T
www.google.com it works find and returns the addresses.
I am using ipchains and have a router between the machine and the cable
modem. I have set both TCP and UDP ports 53 open in both locations.
I am at a loss!
Thanks,
Carlos

Check the contents of your /etc/nsswitch.conf file, and make sure that
your hosts like looks like this:
hosts: files dns nisplus
You can even get rid of the "nisplus" option, if you're not running an nis
service.
