re: how to close port 113

[Jude DaShiell <jdashiel@shellworld.net>]

Install and run arno-iptables-firewall and tell it your internet port like 
eth0 or ppp0 and leave the rest of the defaults alone.  Port 113 will be 
closed once this is done since one of the defaults with 
arno-iptables-firewall is to first deny all portsthen only open up those 
you specifically choose to open.
