For a musical project, I want to connect two sound devices through LAN. One is a Ubuntu 18.04, the other a OSX. To stream real time audio between the two machines, I would like to try to use NetJack. I have seen that after the two machines see each other's Jack, connection between outputs and inputs are quite straightforward.
Before I try, as I don't have the two machines with me and in order to avoid tedious problems when I'll get to work with it, I would like to ask you whether, when connecting a LAN (cable) between the two machines, they see each other automatically or I have to do something (set parameters, tick boxes, restart, do some magic).
