[buug] /etc/service

[Zeke Krahlin]

Another tip from my FreeNetCubs board. Does it sound like a good security
measure, or too much on the brute-force side? (I know Stoddard recommends
a similar method for "/etc/indetd.conf".)

What do all those ports mean?
Posted by Paranoid Chick on 8/2/2000

Your computer has tons and tons of ports available for connection from
outside hosts. Like "8080", "21", 3128", etc..... 

Well, what do all these ports mean? 

Well the IANA has assigned specific port numbers to particular services on
your box. If you are running Linux (as you SHOULD be if you are reading
this) just have a look at the /etc/services file and you'll get an
eyefull. 

It's a good idea to comment out (put a '#' in front of) those services you
know you are not running, like datametrics on port 1645 and radius on port
1812. In fact, if you don't know what a particular service is, chances are
you don't need it and should comment it out!
