This script is not a firewall technically, but I needed a name, and
some total self-centered idiot from #Nuke@EFnet said that I was
behind a firewall, so.. *grin* All this does it makes you look like
you are from the server that your eggdrop is on rather than your
dialup ISP.  So if you dialed-up to America Online and were tired of
being ICMPed every three seconds, you could put this script on your
account (named fire) on the server shells.r.us and you would look like
fire@shells.r.us instead of aoler@132-3-193.ipt.aol.com.  Provided
that both your eggdrop unix server and your irc server have inteligent
kernels, it not only blocks ICMP Echo attacks, but it keeps you from
getting unreached nuked (called "click nuke" by some).  Please
e-mail me any bug reports in this.  This is a very new version. (duh)
The next version will feature: ability to change IRC server and port
without editing the config file and more smarts when killing idxes
(right now, i did not put in any implemtentation of killdcc because if
both sides of the connection close at the same time, eggdrop will
segmentation fault.. even if you 'catch' it..).  This script has only
been tested with Eggdrop1.2.0+kk+pop1+pop2+pop3+pop4+pop5+pop6+pop7
+pop8+sekret-fixez, so if you are trying to run it on something
less than that, be ready for weird results.  THIS SCRIPT DOES NOT WORK
ON EGGDROP1.X OR LESS!  They do not support 'listen' or 'connect'
which are needed for this script.  Please remember: only one client
at a time can use this.. the next version will fix that problem.
I love Kim (NadiaFan@EFnet)!!!
 ##Commands - these command/s can be used from the client to do
certain things.  Only two of them in this version:
 /##HELP - lists commands
 /##KILL - kills the connection to the client, server is expected to
           time out connection if it has not already closed.
