Re: [gentoo-user] a weird problem regarding internet connection...
I have no idea what might have happened yesterday... I got home from a party @5AM and I turned on my computer to listen to some music untill I fall asleep. 5 minutes ago, GAIM logged in, all by itself... I am sure I haven't modified any setting (unless I was sleeptyping). What happened? How can I make sure it's not going to happen again when I'll need my internet connexion more than ever? -- gentoo-user@gentoo.org mailing list

Lovely (hope the party was excellent ;)). Well, just check the firewall rules and check name resolution via dig. Maybe it was just an issue with the name server itself. Might be handy to get another one to resolv.conf. Martin -- gentoo-user@gentoo.org mailing list
[gentoo-user] a weird problem regarding internet connection...
Hello! My name is Andrei. I'm having this weird issue since last night. I went out for a couple of hours, leaving my computer on. When I got home I noticed I had been disconnected from all my IM accounts, ktorrent was stalled, everything was frozen, i couldn't even load a website. I tried restarting the net.eth1 script - nothing. DHCP was working fine, but I still couldn't do any traffic. Today I called my ISP and they sent a guy to check out the problem... He said the internet connection is working fine on his laptop (running windows xp). I tried booting into windows... and I couldn't believe my eyes... it was working :| How could this be possible? I've done some more digging in gentoo, this is what i've got... DHCP - working fine, i've got the same settings as ever (it's a static configuration through DHCP) Pinging the gateway/dns server - works fine. Pinging google.com: it can't resolve google.com Anyone have any ideas about what I can do to fix this? I can't spend this Easter in windows :|

May also want to try pinging 216.239.37.99 which is the IP address for one of many google servers. Hope that helps get you started any way. Post back what happens.

Just because the DNS server is pingable (using ICMP) doesn't mean DNS resolution is working! DNS requests run over UDP port 53 (zone transfers over TCP 53, but that's realy only useful for DNS admins). It could be a problem with your /etc/resolv.conf file. Does it have an entry for the name server? If not that's probably your problem. You may have to check your config files regarding net and dhcp, ie /etc/conf.d/net.eth0 etc. Does the dig command work, or host/nslookup? Try, for instance, ~ dig www.cisco.com +short This gives the most basic info, ie just the servers IP address, if DNS is working correctly. For more elaborate info (good for troubleshooting) try: dig www.cisco.com +nocmd +nostats +noquestion This gives more info, skipping som less useful garbage). BTW, putting +nocmd +nostats +noquestion without the quotes in your ~/.digrc file is pretty useful:) //T -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.6 (MingW32) iD8DBQFGF3lcJDzv6DN+QUkRAucOAJ9GfYu6fzHxwHfVBCp/omm3U/rlBQCgxaJQ 4TBo+cv3MJBoHOqELg88mm8= =sPBc -END PGP SIGNATURE- -- gentoo-user@gentoo.org mailing list
