manually set dns server address

Generally speaking your router/gateway should get an IP address from your ISP. With that it should get the DNS servers addresses. Most then run DHCP to the internal network and tell the clients (your pc) the DNS servers to use, and to use the router as the default gateway. If this isn't working properly then you can set the DNS servers in the file /etc/resolv.conf. Edit this using the following:-

$ sudo gedit /etc/resolv.conf

Then make sure there is an entry for each nameserver in the format below

nameserver <ip address of nameserver 1>
nameserver <ip address of nameserver 2>

When you have save it one time in the file, if your DNS servers don't change, it will work automatically on startup.

Its like people are reading my mind. I am having an issue where mine keep resetting to the gateway's ip address. I have changed the dns server address' in my gateway and can get online for a while after rebooting but eventually it goes out. When I check the file /etc/resolv.conf this is what it keeps showing

search domain_not_set.invalid
nameserver 192.168.1.1
nameserver 192.168.1.1

After I lose connection if I change them it works fine until I reboot.

Thanks-

I have fixed it by setting a static ip address. My router does not change it.

The internet connection was working fine, until all of the sudden at one point I tried to use the dsl through the terminal and this came up:
In file/etc/ppp/peers/dsl-provider: unrecognized option 'nic-eth0--configure--configure'
I've tried to edit this, but it won't let me.
Please help, Thanx! :)

revoke write permissions to /etc/resolv.conf sudo chmod 444 /etc/resolv.conf

Oh now lets choose some DNS servers.

Pick one from http://www.DNSServerList.org

I realised that my router was resetting the DNS to the wrong 192.168.1.1 every 10 seconds and even if I wrote via Network Settings (KDE) or directly into resolv.conf to use an alternative good one (194.72.6.51) after 10 seconds it got overwritten again to the 192.168.1.1 I was getting desperate and furious. Windows machines kept the alternate DNS in IP configuration without problems.
Then I found out (through a OpenSuse Live CD and YAST configuration) that to turn off the setting DNS via DHCP I had to change the resolv.conf instead of

search -name-
nameserver 192.168.1.1

to

domain site
nameserver 192.168.1.1
nameserver 194.72.6.51

That helped, since then the DNS stays as it should and my internet is working 100%

i tried out all these that are suggested here, but i cant manually set my dns because after saving the changed /etc/resolv.conf file it seems to be immediately overwritten. i am a newbie, there is a possibility that i am missing something. any advice?
