Tonyjoy,

As far as I know, the command menu (the GUI) is only applicable when running a listen (=non dedicated) server.

When I run my Linux server, I either connect to the console and type stuff like 'realbot killall' or use in my Windows console 'rcon realbot killall'. Of course, this works for all realbot commands, not only for 'killall'

You can easily check whether Realbot is installed correctly:
- in HL directory, there is a reallog.txt
- a welcome message is displayed when you connect to a game
- issue 'meta list' on the Linux HLDS console

Hope this helps
