[NTLUG:Discuss] how do I run two instances of named?

[Randall Gibson]

	You can find which services are bound to which port in /etc/services/ You can find the actual service commands / setup in /etc/inetd.conf
	While in /etc/inetd.conf , you may want to comment out all lines that have services you dont want/need, even if you dont have them installed. Also you need to "killall -HUP inetd" once done to have it re-read the configuration files you have setup.
	Firewalling is much different, it involves kernel level configuration, and special routing to be setup during startup. I suggest you read the howto, and try a basic probe of your machine at : https://grc.com/x/ne.dll?bh0bkyd2 If you plan to do ipmasq , adding in firewall support is just a few steps more, so is well worth it.
