Hello everyone... Any Unix users out there?

I'm looking for an opensource client for Linux/BSD with a GUI and supports file sharing. Any suggestions? I'd prefer a GTK+ client, but any non QT software is welcome.

I've used Java clients, but I'm not impressed with any of them, and my current client (GTK_Gnutella) works great, but doesn't support sharing which is disappointing as I don't enjoy being a leech as most do. After all, I've got a great cable modem sitting idle most of the time when I could be sharing files...
