Manually Specifying DNS Server in Linux

[Aaron]

How can I manually specify the DNS server I want my adapter to use? I've tried editing /etc/resolv.conf and with the interface up and down and various combos, but it always gets set back to the subnet's DNS, and I want it to use mine, running on another machine. Maybe its something obvious, but what can I do? (from the command line preferably).

Thanks

nameserver ip

I do believe.

There is no signature

I already tried that, it doesn't exist on that box. Its a more or less default debian sarge install if that helps.

No reason it shouldn't work--it worked on my knoppix install. Wait for Matty or someone to see this.

Do you use DHCP?
If so, I think it sets the DNS-Server automatically.
You can change that (at least in Gentoo) in /etc/conf.d/net

Sorry for the lousy English

Yeah, what Impi said. DHCP by default attempts to obtain the DNS server by itself. You need to specify in the net file what DNS server you need to use.

If your using DHCP, just restart your networking handle (`/etc/init.d/networking restart`) or run the DHCP client (`dhclient`).

Otherwise...
1) Set your IP: (`ifconfig eth0 IP_ADDRESS'), where 'eth0' is your actual interface (it problably is eth0) and IP_ADDRESS is the IP address you want.
2) Set your gateway: (`route add default gw IP_ADDRESS`), where IP_ADDRESS is the address of your gateway(router).
3) Set your name server: edit /etc/resolv.conf: it should contain one line with the following syntax: "nameserver IP_ADDRESS", where IP_ADDRESS is the IP of the name server you want to use.


Now, isnt DHCP soooo much easier? http://forums.massassi.net/html/tongue.gif

:P

The goal is to be smarter than the DHCP! I want everything the DHCP gives me except for the name servers. Anyway, I'll try editing it again, and get back to you with specifics.
