Question dns server and /etc/resolv.conf

hi, all,

I use a ubuntu 504-i386. I have a home AP/router and my system is configured to get ip from DHCP service of the AP. The problem is: after every system bootup the /etc/resolv.conf is written as:

search domain

my /etc/network/interface is:
mapping hotplug
script grep
map eth0

# The primary network interface
iface eth0 inet dhcp

Line 2-4 are 3 non-effective DNS server address, and if i keep this unchanged my access would be slowed down or disabled due to the DNS trying. However, if I changed the file, deleting the 3 useless lines, after a while the system will change it back to the content above. How can I do to overcome this problem?

When SUSE's dhcpcd writes over the resolv.conf, it always puts a comment in the top of the file telling you how to avoid doing this. It may also be an option on your router to not publish that information to dhcp clients.

The obvious solution is a static address, but perhaps that'd be a PITA for you for other reasons. You could try contacting your ISP and find out why they are sending out bogus DNS information....obviously that is the case if it survives a reboot of your access point.

You can edit the /etc/dhcp3/dhclient.conf file to over-ride the information but whatever DNS addresses that you plug in as an over-ride will apply to *all* dhcp connection. That might not help you much...
