kashif2131971 · 07-14-2009, 08:25 AM

using redhat enterprise 4:
my resolv.conf is over write by the internet provider

my hostname is pc1.homeserver.in
my domainname is homeserver.in

before connecting to internet by resolv.conf is:

nameserver 192.168.1.1
and domain is resolv by dig command but everythink goes fine.

but when I connect to internet the resolv.conf change to

; generated by /sbin/dhclient-script
nameserver 192.168.15.1

because of this my own domain is not resolv its my local domain
help me out of this problem

Try

sudo vim /etc/dhcp3/dhclient.conf

Edit the following two lines to read as

supersede domain-name “mydomain.com”;
prepend domain-name-servers 192.168.1.1

Wait trying to test this

Also if not above you can try to add /etc/dhclient-enter-hooks that
contains the following:-

make_resolv_conf( ) {
logger -t "dhclient-enter-hooks" "Doing nothing to /etc/resolv.conf"
}
