[linux-audio-user] Netjack et al.

Hello, Firstly i would just like to say how useful this list is, i have been subscribed for a few months now, but never put any input in. Now to my problem/issue: In my studio i have 2 pc's running ubuntu, 1 upstairs in the recording bit, and 1 downstairs used for the actual recording. The 2 Pc's are connected via LAN and i can ssh into them. What i want is to be able to play back things from the downstairs pc through the upstairs ones speakers. I could just run up some more cables but that seems excessive. A quick google made me have a look at netjack, though i cant seem to install it. Have untared the file and done a sudo scon -path-to-jack='/home/jack-source/' But this just sits there doing nothing Any advice/ideas for my situation? Cheers Chris
