Hi, I've setup a small LAN of two desktops running CentOS 5 in a medical office. Both are connected to the Internet via a small modem/router. Recently I played around with FreeNX on my own desktop, and I'd like to install it on these two computers. On my PC, I just redirected port 22 in the router, so SSH (and thus FreeNX) requests from the outside get redirected to my desktop PC. (And yes, I have a strong password :oD) I'd like to handle the two PCs from the medical office remotely with FreeNX. I figured that the best way to distinguish them would be to assign a different port for SSH to each of them, and then redirect each of the ports respectively. 1) How do I choose different port numbers for SSH ? Any conventions or caveats for this ? 2) How do I configure these different ports ? By that, I mean : how do I tell SSH to use them instead of port 22 ? Cheers, Niki
