You ask about exchange and don't say whether 5.5 or 2k. MSX 5.5 requires RPC unless you only implement Internet services (pop, imap, smtp, ldap). I don't know if 2k requires RPC.
You say you're using the RH firewall. I guess that means you are using ipchains? /etc/services shows the standard port each application listens on. The links to ipchains docs will guide you through setting up the fw. ??????? 3. If there's opened-port by the firewall, how can I secure it? ????????? Read the ipchains docs. Any app running on the fw reduces efficiency of the fw and exposes the application to greater risk. As a general rule DON'T install apps on the fw.

I have done this very easily with iptables with the http://www.linuxguruz.org/iptables/scripts/rc.firewall_015.txt Or you can use ipchains with the ofllowing: http://netfilter.samba.org/ipchains/HOWTO-7.html > 3.

You have to set up your firewall as your mailserver, which is not what the firewall should be doing... -- Tony Zafiropoulos FixMyVirus.com Cel: 314-504-3974 [EMAIL PROTECTED] Best way to reduce your virus exposure?
