redhat network problems

[bs]

ease excuse this newbie's ignorance but I have RTM and I still can't get 
my two Redhat 7.3 boxes to talk to eachother. I can ping from one to the 
other but everything else is refused. Nmap shows just a few ports open.

Starting nmap V. 2.54BETA31 ( www.insecure.org/nmap/ )
 Interesting ports on stimpy (192.168.39.1):
(The 1547 ports scanned but not shown below are in state: closed)
Port       State       Service
111/tcp    open        sunrpc                 
113/tcp    open        auth                   
199/tcp    open        smux                   
678/tcp    open        unknown                
1024/tcp   open        kdm                    
1026/tcp   open        nterm                  
6000/tcp   open        X11
