I've 2 linux computers, one redhat (client), and one ubuntu (set up with shared internet connection as described here)At the moment, on the wired connection between the computers, I can ping the other computer from both sides; IP addresses are setup statically.  The ubuntu computer has access to the internet through wireless.I want to setup the redhat client to be able to access the same DNS server as the ubuntu one uses.  In the article above, it is assumed that the client is another ubuntu box, and they advise to do the following:prepend domain-name-servers 208.67.222.222,208.67.220.220;However, the redhat client doesn't have the file /etc/dhcp3/dhclient.conf.  Is there another way of achieving the above in redhat?(I've tried to setup the ubuntu box as a dhcp server using dnsmasq, but it didn't work)(BTW, I thought I needed a crossover cable for this type of setup, but that didn't work - an ordinary ethernet cable was fine)
Static DNS setup on client of shared internet connection
ubuntu;networking;rhel;connection sharing
I hadn't set up NAT on the ubuntu server.When that was set up I didn't need any 'prepend' stuff as I was able to set the IP address of the DNS server on the client (redhat, in resolv.conf) to be the same IP address as the ubuntu server was using.  NAT handled the translation from one network to the other.The instructions for setting up NAT on the ubuntu server I got from here:http://ubuntuforums.org/showthread.php?t=713874 Thanks fschmitt for your answer.
