 |
|
I just got my new connection from my new ISP. Now I've got some trouble configuring it on my Gentoo linux pc. Emerge can't connect to it's servers, postfix gives an error about the hostnames not being found, etc. I've tried upgrading my kernel from 2.4 to 2.6, but no luck.
My gentoo-pc connects via my router to the internet. The router gives the ip's and dns's via dhcp
I can ping websites though it takes a long time:
i-lynx root # ping www.demon.nl
PING www.www.nl.demon.net (194.159.73.70) 56(84) bytes of data.
64 bytes from 194.159.73.70: icmp_seq=1 ttl=62 time=19.6 ms
64 bytes from 194.159.73.70: icmp_seq=2 ttl=62 time=17.6 ms
64 bytes from 194.159.73.70: icmp_seq=3 ttl=62 time=17.4 ms
--- www.www.nl.demon.net ping statistics ---
3 packets transmitted, 3 received, 0% packet loss, time 40039ms <<<<<!!!!
rtt min/avg/max/mdev = 17.454/18.228/19.609/0.978 ms
Any ideas? Need more info?
Edit: My apache webserver is reachable and fast... It seems that incomming traffic is ok... but outgoing......
/etc/resolv.conf gets it's information from dhcp |

what happens if you ping a website directly using it's IP? Is the huge initial delay still there?

THeFLyZoNe,
Did you update your router to point to the new ISPs nameservers ?
Do you have the old ISP nameservers in your /etc/resolv.conf ?
They may timeout now and you would have to wait for that.

Router is new, installed with modem, so no old config.
Resolv.cof gets it's nameservers from DHCP, provided by the router.
Btw, all the windows pc's works 100% so router configuration must be ok |

err no.
Windows and Linux do things differently, so that doesn't hold all the time.

it is a name resolve problem. Take the ethernet card down, destroy all the dhcp cache's for it (/var/lib/dhcp, /var/cache), bring the ethernet back up and see if that affacts a chance in the resolve.conf file. It probably will, and then that should hopefully take care of the massive dns delay problems.
