problem with resolv.conf file
I am using redhat 9 and I have configured DNS
I remove sendmail and install postfix as my MTA.
without configuring anything I am able to send mail to yahoo and hotmail..
whenever I am online through dial up connection...
it works...I can browse and I can send mail...
But after disconnect...my /etc/resolv.conf file autmatically changed..
then I have to give information of my nameserver again and then my DNS starts working again..
any clue why this is happening....how can I keep my most important file../etc/resolv.conf unchanged...
