Get DNS automaticly

I configure my network interface to use DHCP (Redht Linux 9.0). It
does not seem it gets DNS automaticly through DHCP, I have to manualll
configure it. How do I makr it get that automaticly.
When I use windows, if I configure the interface to get IP through
DHCP, it gets DNS automaticly. I guess all this info should be
included in DHCP messages.

Thanks

dhcpd.conf:

....
option domain-name-servers 192.168.0.1;
....

Replacing, of course, the IP with the correct IP address of your network's
DNS servers. You can specify more than one; separate them with a space.

My problem is at client site. My PC is dualboot and connect to my home
router.
If I boot into XP, I can check my PC get IP, GW and DNS addresses. NO
problem.

If I boot into linux. The interface is up. But I can not go anywhere
until
I put the the DNS address manually.

Question is of cause why?
question 2 is if there is command equivalent to ipconfig on XP to get
all information the linux get through DHCP protocol?

My problem is at client side. My PC is dualboot connecting to mynhome
router.
if the PC route into XY, everthing working fine. If I boot into linux,
I can not browse anywhere until I manually put in the DNS address.
My question is first why?
My second qustion is if there is equivalent command of ipconfig on XP
on linux
to get information the PC gets from the server.

Always ask.

Run your network configuration tool (on my Fedora Core 1 system it's
Main Menu -> System Settings -> Network), select your networking device
(if there's more than one), and click on "Edit". In the DHCP settings
you'll find a checkbox for "Automatically obtain DNS information from
provider".

Nic not set to get dhcp info?
Firewall set too tight?
dhcp client not installed ?
Any info/errors found with grep dhcp /var/log/messages

depends on which dhcp client you running.

ps aux | grep dhc
Might return which dhcp client you are running.

If using dhclient
cat /var/lib/dhcp/dhclient-eth0.leases

If using dhcpcd
cat /etc/dhcpc/dhcpcd-eth0.info
