Squid Problems

I am running Suse 9.1. I have Squid set up to run as a proxy for dansguardian. I got it all up and running good. The only problem is that all my internal web servers names aren't resovled by the proxy. I have one internal server called http://MUSForum with an IP of If I try and go to http://MUSForum I get an error message of

The requested URL could not be retrieved

While trying to retrieve the URL: http://musforum/

The following error was encountered:

Unable to determine IP address from host name for musforum

The dnsserver returned:

Server Failure: The name server was unable to process this query.

This means that:

The cache was not able to resolve the hostname presented in the URL.
Check if the address is correct.

Your cache administrator is webmaster.

Yet if I type in the IP I can go to it. I've been told the way to resolve this is to install squid as a reverse proxy with the following option --disable-internal-dns. I first downloaded the squid source from, but it seems that that source doesn't work with Suse. So when I installed squid with Yast it all worked good. How can I give the --disable-internal-dns option if I can only use the YAST package??? Is there a way to do this option if I install with the rpm command?

Maybe you could define musforum in the /etc/hosts file on the proxy machine?

I did put the internal web server in the hosts file and that doesn't work. Using the --disable-internal-dns option would allow me to tell the proxy server how to resolve names (whether to look at hosts file first then dns servers etc..). I was able to work out my problem because Windows Active directory lets you set an option when you set the proxy settings for IE to not use proxy for internal servers. So that worked out. This would have been an issue if I wouldn't have had a windows domain. I guess I would have had to use RedHat instead. This is something Suse needs to address because I swear the squid source doesn't work with suse.
