 |
|
I think this is a dns problem. When my network comes up, I can ping any ip address, but the moment I try to ping a domain name that is associated with that IP, it cannot find the host. /etc/resolv.conf looks like this
| Code: | nameserver 128.118.25.3
nameserver 130.203.1.4
search zoominternet.net
|
It worked on friday, and when I brought my laptop back to school today, it does not work. I haven't changed either /etc/conf.d/net or /etc/resolv.conf
This behavior is weird, any help? |

Do you have an /etc/nsswitch.conf? If so, that could be perturbing results if modified incorrectly.
Do you have dig/nslookup installed? If so, try doing: | Code: |
# nslookup
> server 128.118.25.3
Default server: 128.118.25.3
Address: 128.118.25.3#53
> 128.118.25.3
Server: 128.118.25.3
Address: 128.118.25.3#53
3.25.118.128.in-addr.arpa name = otc2.psu.edu
> |
Execute those two commands at the nslookup prompt, and see if otc2 can list itself. Since it worked for me (not on campus), if it fails for you, it's likely something specific to your host. As for what, I dunno. Have you installed anything lately that might have modified networking/kernel code? Compiled a new kernel? |

I'm having similar problems, but not quite. I just installed Gentoo today and during the install process I had good DNS resolution. However, after recompiling the kernel, it's borked. So, I'm guessing I've gotta do something to get name resolution back since I recompiled? What might that be? nsswitch.conf doesn't seem to have been modified (timestamp didn't change) so I'd guess that's fine. Any suggestions?

Eh... Following up to my last post, it appears as though it's network-related. I can ping everything inside my network and I'm ssh'd into my Gentoo box now, but I can't get outside my network. The Gentoo box is the only one having troubles. Here's the results of a ping
| Code: |
PING 207.172.3.8 (207.172.3.8): 56 octets data
sendto: Network is unreachable
ping: sent 64 octets to 207.172.3.8, ret=-1
sendto: Network is unreachable
ping: sent 64 octets to 207.172.3.8, ret=-1
sendto: Network is unreachable
ping: sent 64 octets to 207.172.3.8, ret=-1

I promise I'll stop posting now.  I didn't have a default gateway set. In case there's another n00b out there wondering where it's set...it's set in /etc/conf.d/net at the bottom. Or, you can set it manually with:
route add -net default gw 192.168.0.1 netmask 0.0.0.0 metric 1
