Sharing Internet Connection DNS?

My home network looks like this:

internet <--> host1 <--> host2

host1 can resolve host names out on the internet just fine.
host2 can do anything it wants to on the internet, but unless the
host name is in /etc/hosts, it can't resolve it. Everything
works with host2 if I use IP addresses. I'm a complete newbie to
DNS stuff, but is that where my trouble lies? How can I get host
name resolving to work on host2?


Thanks....

Does your /etc/resolv.conf file on host2 have the same DNS servers as
the /etc/resolv.conf on host1?

What is the contents of /etc/resolv.conf on each system?

One way is as Scott hints, use the same nameservers on each ...

Another way, pretty easy to manage, is this:

(It appears my first response did not go through...)
What are the contents of /etc/resolv.conf on each of the hosts?

Copy the /etc/resolv.conf from host1 to host2, and make sure that host2
can ping the nameservers.
