How to configure RHEL4 to obtain DNS server automattically
 

Hi

My problem is that i have a broadband connection and it supports DHCP. For this i need to update the resolv.conf file with the DNS server names.
Earlier i used to do it manually. Can we do something so that the resolv.conf file gets updated itself and we do not have to go there and update evrytime.

i saw the following some where :-

we update /etc/sysconfig/network-scripts/ifcfg-eth0 with :-

PEERDNS=<answer>, where <answer> is one of the following:
yes — Modify /etc/resolv.conf with information from the server. If using DHCP, then yes is the default.
no — Do not modify /etc/resolv.conf.

Please explain the above to me. also tell me does it work ? Is there a way to do it via a GUI.

Hi,

Then answer is simple, you should use the PEERDNS=yes parameter in
you ifcfg.ethXXX file that way when you get the IP of your machine
via DHCP the /etc/resolv.conf file should be updated.

In order to check if your resolv.conf file is updated correctly, the
first line in that file should be:
; generated by /sbin/dhclient-script

Also check that BOOTPROOT=dhcp is set in your network configuration
file.

Best regards.
