Warcraft 3 Server Software?

http://ubuntuforums.org – I want to create a dedicated server out of spare computer parts for Warcraft 3 LAN battles, but for the life of me I cannot find any software meant for that purpose. Any suggestions? The operating system will be Linux (duh), specifically either Xubuntu or Ubuntu Server, depending on whether or not I'm able to do things without the assistance of a GUI. (Hardware)
