     rvscan version four release [rvscan-v4.tgz] 
         unix remote vulnerability scanner 
::::::::::::::::::::::::::::::::::::::::::::::::::::::

INFO:
hopefully this version will be a lot more reliable. several people tested this out for me, and i fixed all the bugs that they found so far. everything should run smoothly, but i don't recommend using the -v (verbose) flag, because its just not pretty. check the 'ChangeLog' file to see whats new in this version. enjoy.

WARNING:
i am in no way responsible for what you do with this tool. It should be considered very dangerous, and is merely for local security testing (NOT HACKING). if you *do* scan things outside of your network, then don't send me hate mail from your jail cell, because it will go straight to my trash can. of course, this is for educational purposes only; the definition of educational is up to you.

REQUIREMENTS:
a *nix system with telnet, rpcinfo, showmount, nmap, and host.

RESOURCES:

web: http://chickenz.net/og
irc: elicit at #og on irc.ndrsnet.com

THANKS:
all of #og. shekk, robosok, orbflux, and ka0z for bug testing.
