How do I get my DNS from DHCP?

[msulli1355]

This PC has a static IP address. I did this back in the days when there were three Linux machines running on my LAN. Now there is one Linux machine and two Windows machines, but the Windows machines ocassionally need to connect to the Linux box because the Linux box is the only one that I use for making backups. The past few days my Linux box has had a lot of trouble connecting to outside the LAN. I suspect it's because of DNS.

Here is my /etc/resolv.conf file:

michael@camille ~ $ sudo cat /etc/resolv.conf
Password:
# Generated by net-scripts for interface eth0
nameserver 127.0.0.1
nameserver 24.116.0.53
nameserver 24.116.2.50

Here is my /etc/conf.d/net:


michael@camille ~ $ sudo cat /etc/conf.d/net
dns_domain_lo="espersunited.com"
config_eth0="192.168.0.3 netmask 255.255.255.0 brd 192.168.0.255"
routes_eth0="default via 192.168.0.1"
#dns_servers_eth0="127.0.0.1"
michael@camille ~ $

I have a named server running, which is why my first entry in /etc/resolv.conf is the loopback address. The two addresses under that were chosen by the liveCD I used to install last April. I suspect that those addresses have changed. I want to change those addresses to addresses provided by my cable modem, but I can't seem to find any guide to tell me how to do that. I want to keep my static IP, but I want DNS through DHCP. Is there a way to do this, and if so, can anybody point me in the direction to finding it?

I don't think this is possible. It is either static or dhcp. I think the simplest solution is to switch to dhcp and reserve the IP for your linux box's MAC in your dhcp server.

Here is an example that specifies DNS but gets IP from the router. The router is configured to always give 192.168.102 to the MAC address:

if you use a router, it is your router that will resolve dns for you with the dns of your the provider
dns_servers_eth0="192.168.0.1"
