Linux security...unwanted services

Appears to be a very useful link...

Tells you which services should be active and which should not. It even tells you how to turn services off! (rc.d)

Enjoy!

Thanks Dave. My policy - if I aint using it - turn it off

This only tells you about services started by Red Hat's init scripts.

Another thing to look out for is your /etc/inetd.conf file. Any line that's uncommented in that file is an open port. I have the whole file commented out (I probably could've just deleted it but I kept it just in case).

Of course, if you're actually using any of these services (ftp, telnet, whatever) you should keep them on.
