Yes, I know I could do that. It's OK when there are only 2 boxes but what if I had a small office setup with, say, 100 PCs. It's not so practical then. I'm interested in finding out if there is another way to make this work.

I think my understanding is a little lacking on this subject (one of many).

Here is my simple and, I suspect, very common setup: 2 PCs, one FC6 Linux, one Windows Vista and a Linksys wireless router. A DHCP server on the Linksys determines the IP addresses of the 2 machines.

My question is: is it possible for either machine to ping the other without having to make an entry in its local hosts file? Making entries in the hosts file doesn't seem like a good idea since the IP address could, in theory, change.
The Linksys is a WRT54G and I don't think that it contains a DNS server. The names of my 2 machine should never get to a public DNS router since they are on a private network.

I was told by an expert to put my own ip and the ip of my DNS servers in /etc/hosts/ and it now looks like this:

[karl@k5di ~]$ cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
216.31.109.91 k5di.com
216.234.192.92 nameserver
216.234.213.130 nameserver

So you should do the same thing I think.
