Can someone give me a good external rcon to use? Having trouble finding one.

I wrote one in ruby a while ago. Its not particularly good, more a quick'n'dirty implentation, but it should work:: http://kadaverjack.planetnexuiz.de/downloads/rcon.zip

2.4.1 or the hotfix contain a perl rcon script, when using linux xqf comes with an rcon tool (gui and commandline) also hlsw is supposed to have one..
