computer loses dns settings

[andre75]

I am not exactly sure how to describe the problem, but this is whats happening:

I have set up a machine on debian and after a while it loses the dns, so when I type:

ping: somesite.com

it times out but when I type:

ping: xxx.xxx.xxx.xxx <-some existing ip
I get an immediate response.

Anything I can do?

what kind of ip are you using? static or dhcp

if static you need define the dns servers for the system
make a file in /etc on name resolv.conf and add the nameserver
syntax:
nameserver xxx.xxx.xxx.xxx

each line each dns server

I am using dhcp, but I would much rather switch to static.
I will give your suggestion a try.
It only seems to happen if I call curl from a php script. Don't know why.
