Hey Everyone,
I'm thinking of setting up a minecraft server on my Ubuntu machine and I usually use hamachi (on my win7 laptop) to allow friends to connect to a server but there are a couple of concerns with linux hamachi:
1. It is only in beta for Linux (no gui, just command line)
2. It allows 4 people max on the free version

Does anyone know of any free software which is a reliable alternative to hamachi? What are your experiences with these programs?

Cheers,
Stu
