I was out of town and I just read your post. I would strongly suggest
that you download the free manual about hardening RHEL 5,  in .pdf
form, from nsa.gov   As I recall, they do *NOT* recommend running more
than one service on a server, if possible. Among many other
recommendations. Search for "Guide to the Secure Configuration of Red
Hat Enterprise Linux 5", Revision 2, December 20, 2007. HTH
