network up, but not resolving correctly.

BrianK · 07-02-2004, 09:19 PM

One of my machines has a working network, but isn't resolving names properly.

the entry in /etc/resolv.conf is correct (set to the ip of my router - same as the rest of the machines in the office), but when I try to "ping yahoo.com" I get nothing.. if I try to "ping 66.218.71.198" (which is yahoo) I get a proper ping.

Any idea what might be the cause?

Is this machine set to renew dns server on dhcp?

while trying to resolve the hostname run something like iptraf on that interface and log any paket that is transmitted. maybe this will give you a clue.

I'm having a similar problem in slackware 9.0 using a D-Link router: I can only visit several sites. Whenever I ping some sites like ctan.org it says host not found; yet I can visit them under windoze. My router is configured as DHCP server so there might be something wrong with the renewal of the DNS server. I hope when I resolve this problem I could help you in some way too.

try invoking:
host 66.218.71.198

For more verbose output, also invoke:
host -v 66.218.71.198

Suggestions:
1) you have a typo in /etc/resolv.conf
2) check /etc/nsswitch.conf, where your "hosts" line should look something like:
hosts: files dns

have you tried using dig?

Ahh ha! I just made this machine an NIS server. In my attempts to get things going, I removed the "dns" entry from the hosts line in the nsswitch file.

Thanks!
