[smkamene]

Hello guys. Every time i reboot my box i have to manully go in and modify /etc/resolv.conf . I am using DHCP. Resolv.conf does not get populated the searchname field. What is wrong? How can i stop dhcp client from modify my resolv.conf.

This is a dynamic file, any changes will be overwriiten when dhcp starts. The namesevers should be passed into that file from the DHCP server, if it is blank I would look at the DHCP server to make sure it is working properly with the proper nameservers

There is also a way to set ones, but I don't have the resolvconf(8) man page available, maybe someone knows this process?

Actually, the behaviour of your DHCP client is probably what you want to modify. The client daemons have options that you can specify which determine the way in which the info obtained from your DHCP server filters into your system settings.

For instance, if you use the "dhcpcd" client, specifying the -R option in whatever script starts the daemon wil prevent it from overwriting your /etc/resolv.conf file.

With redhat PEERDNS=no will set the "-R" option for dhcpcd, works with dhclient and pump also.

Thank you guys. "PEERDNS=no" did it.
