Dave Mangot commented on CDV-354:
---------------------------------

The oddity isn't really with CentOS at all.  It also has nothing to do with the 
way that we open ports other than that we use an RMI server.  The RMI server 
returns whatever hostname(1) resolves to back to remote clients.  Depending on 
how you do your Linux install (on the  network, on a desktop, etc) you may wind 
up with only a loopback address in /etc/hosts after the install.  If this is 
the case then the RMI server will not work remotely for you.  

The test is as Gary describes.  The solution is to fix the networking so it is 
correct for a machine that is operating on a TCP/IP network.

This is not particular to CentOS, we've seen it on SuSE and reproduced it 
reliably on Fedora.
