I'm getting closer - I can do a nslookup but I can't ping - huh?

[Jim Lopresto]

Hi:

Have you checked the /etc/resolv.conf file on the Linux box to see where it is
pointing?

It should look something like the following:

search  andigilog.com
nameserver 209.179.179.18
nameserver 207.217.120.13

My nsswitch.conf file looks ok

hosts:          files dns
networks:       files dns

Ok, here is a real stumper...

My clients can ping by name, using Linux box as a DNS resolver. But, the
Linux box can't ping by name? Huh.

Example:
I can ping 204.71.200.243 (yahoo.com) with my linux box (DNS machine)
I can't ping yahoo.com with my linux box.
I can ping yahoo.com with an NT box using linux for DNS server.
I can ping 204.71.200.243 (yahoo.com) from NT using the Linux Box as a DNS
server.

Ok, now what... I really am stumped.

Thanks so much

Steven
