Many > many thanks!! I wouldn't use a Belkin KVM, regardless of what your LUG might say. They have shown themselves to be quite unreliable. If all the machines are on the same LAN and your primary concern is simply sharing the keyboard and mouse (and can live with multiple monitors), then I'd recommend using synergy. You run synergys (server) on the primary machine with a config file that defines how the screens are physically configured (e.g. primary machine is "X", "Y" is to the left of "X", and "Z" is to the right of "X"). Sample: ------------------ CUT HERE ---------------------------------------- [root@prophead ~]# cat /etc/synergy.conf # Synergy configuration for Rick Stevens at AllDigital # Author: Rick Stevens, AllDigital, Inc. # Last Edit: 19 January 2018 # # Note: This is used on prophead ONLY which runs synergys (the # server application) and synergy uses TCP port 24800, so open that # on the firewall. section: screens prophead: golem4: macbook: end section: aliases prophead: 192.168.1.50 golem4: 192.168.1.52 macbook: 192.168.1.60 end section: links # Screen configuration: # +---> macbook <------> prophead (main) <----> golem4 (laptop) <---+ # +-----------------------------------------------------------------+ prophead: right = golem4 left = macbook golem4: left = prophead right = macbook macbook: left = golem4 right = prophead end section: options switchDelay = 500 screenSaverSync = true end ------------------ CUT HERE ---------------------------------------- The other machines run synergyc (client). Using the above layout, when I bump the cursor over the right edge of the primary display (prophead), the cursor and keyboard switch over to the machine defined to be on the right of the primary machine (in this case, golem4). If I hit the right edge of golem4 (or move it off the left of prophead), it switches to the macbook. Like I said, this just shares the keyboard and mouse...you still need multiple monitors, but it works for my needs. And the cut-and-paste buffer runs on the server (so you can cut from golem4 and paste it into the macbook if you want).
