Running processes...

Hello list,

Which of the processes can I safely block  from the internet via ipfw?  Here's 
an nmap output from one of my servers.  I would really like to tame this 

Starting nmap 3.50 ( ) at 2004-02-14 06:41 CST
Interesting ports on localhost (
(The 1646 ports scanned but not shown below are in state: closed)
21/tcp   open  ftp
22/tcp   open  ssh
25/tcp   open  smtp
53/tcp   open  domain
80/tcp   open  http
110/tcp  open  pop3
443/tcp  open  https
587/tcp  open  submission
783/tcp  open  hp-alarm-mgr
3306/tcp open  mysql
6667/tcp open  irc
6668/tcp open  irc
9999/tcp open  abyss

Nmap run completed -- 1 IP address (1 host up) scanned in 9.730 seconds

Port 9999 is an irc port for server connections, for anyone who's wondering 
what that's doing there.  I mainly need to get rid of 783, 587.  What are 
those anyways?  Also, what's the name of that app that basically makes all 
ports appear open and logs connection attempts?  Thanks.
