DNS doesnt work in any distro
 

Ok, i've tried knoppix, ubuntu, gentoo, mepis and none are able to do DNS lookups. I have a 700m dell laptop, the builtin wireless works sorda on most but doesnt lookup dns, built in doesnt work most of the time and doesnt find DNS, i got a PCMCIA card that is detected, but it wont do dns.

Funny thing is it wont do it on my work network either, except the PCMCIA card did for a while, but now i'm back home and nothing. I can ping my dns servers, i see them in /etc/resolv.conf, what else does it need? every other machine on my network has no trouble with DNS.

I can point it to my NAT router (192.168.1.1) and it resolves but very very slowly (minutes)

I'm so lost because it happens in all linux distros, got gentoo 1/2 installed but cant because i cant emerge anymore :(

only reason i got this 700m was for linux, help me not use windows...

you have a router... so I assume you are running as a dhcp client?

yes, and it gets all the right info too, dns, ip, gw, subnet... thats why it's so confusing to me.

first thing i would do is confirm that your firewall allows outbound udp packets on port 53. if that's open, then i would run tcpdump in a terminal while you try connecting to a webpage or whatever, and see what's happening to the packets.

what does ifconfig say and what does your router say?

run

#tail -f /var/log/messages

and see what is happening

Its asking all my name servers for the IP

IP 192.168.1.50.domain > 66.133.170.2.domain: 25252+ A? slashdot.org.frontiernet.net. (46)

now i dont see why it's adding my isp's domain to the end.

it was my search domain but I took it out of my resolv.conf and it didnt change. I guess both my wirless and wired are working poperly, i can ping inside and out via IP (i'm in knoppix 3.9 right now)

edit:
i'll ssh in so i can copy/paste
my /var/logmessages hasnt shown anything yet

ifconfig:
knoppix@3[~]$ ifconfig
eth1 Link encap:Ethernet HWaddr 00:12:F0:7F:6D:2A

ummmm ok now for not apparent reason it's resolving domains... no idea why.

going to put knoppix on my hd and reboot, see what happens.

grats! at least it's working, hehe.

if you are using dhcp from your firewall then it should be no prob.

seems to me that your dns is all messed up.

traceroute to a site and grab the dns on the way and use route to add it.

Give yourself a static internal address with a gateway and dns.

mcd: ya, for how long :D

rkettle:" traceroute to a site and grab the dns on the way and use route to add it."

little confused on what you mean.

here's a traceroute to www.yahoo.com (took a long time...)

tcpdump when i do host www.linuxquestions.org, doesnt give me back the ip.

ok, i swaped out routers (i have 2 extra (me and my bro are home from college)) and it works fine... stupid router i'm gonna go smash it!

Thanx for your help, now if i could install gnoppix from the cd hehe
