Thread: dns resolving apparently not working

hello,

i've installed xubuntu 11.10 on new pc without issue, have configured network, dns resolution apparently doesn't work. here's did:

1) uninstalled network-manager prevent putting nose manual configuration:

code:

apt-get remove network-manager network-manager-pptp

2) edited /etc/network/interfaces get:

code:

auto lo iface lo inet loopback  auto eth0 iface eth0 inet static address 192.168.31.150 netmask 255.255.255.0 gateway cerbere

this seems work far because can @ point ping both file server , gateway.

3) edited /etc/environment add:

code:

http_proxy="http://{my.proxy.address}:8080/" ftp_proxy="ftp://{my.proxy.address}:8080/" https_proxy="https://{my.proxy.address}:8080/"

4) edited /etc/resolv.conf get:

code:

nameserver 1.2.3.4 5.6.7.8

(with actual triple checked dns ips, )

then, when try access internet, error message explaining name of proxy unknown. similarly, when trying use:

code:

apt-get update

it fails, saying unexpected happened while trying find proxy because no address associated it. looks dns issue me (or proxy one, other computers on same network access internet , repository).

guess may simple problem, don't see right now, grateful hint have. way, it's configuration i've been using (gnome)ubuntu 10.04. more year now, wonder if changed between versions regarding basic network configuration.

thank you.

(and happy new year! )

edited /etc/resolv.conf get:
code:
nameserver 1.2.3.4 5.6.7.8

it should be

nameserver 1.2.3.4
nameserver 5.6.7.8
