Im trying to close port 111 and others...

I foudn this at O Rielly:

I can disable the sunrpc and printer daemons by becoming the superuser and adding the following lines to /etc/rc.conf:

portmap_enable="NO"
lpd_enable="NO"

He was using Free BSD as an example. Im using RH 7.2 and cant find rc.conf in /etc. I have about everyother rc file but cant find this one. Must be called somethng different in Linux. Where could I find this file to edit?

To close the port you should stop the service at this port or have it firewaled. I haven't heard about something similar like the commands you'v mentioned in Linux.

In Red Hat, you can either edit the contents of the /etc/rc.d/rc[0-6].d directories by hand or use the supplied "chkconfig" command. The scripts located in those dirs control which process get started/stopped at which run levels (for instance, run level 3 for multi-user, non-x or level 5 for multi-user, x-desktop).

The command "chkconfig --list | grep on" will show you which services are enabled for which run levels. To completely disable a service, run "chkconfig --del <name>". You can also specify certain levels via "chkconfig --level <levels> <name> [on|off]"

I know that's a lot of info, but "man chkconfig" should help if you get stuck/confused. You could also use ipchains/tables firewall rules to block outside connections to these ports, but if you don't need them, shut 'em off!

Kill HUP, god bless your soul! Ive been looking for something like this! Now I know how ot close the services on ports! Ha! This is by far the best way to tighten your linux box if your just starting out and dont know how to make rules for ipchains.
