You'll need to have port 24800/TCP open on ALL machines involved in the synergy config.

I added the port reservation on both sides, but the client still says it failed to connect - connection refused. Most annoying. It might be something to do with the work network config - I'll have to ask... It smells suspiciously like the synergy server isn't running on the machine with the keyboard and mouse. On the server as the root user, try: netstat -lpnt | grep synergy and verify that synergys is running and listening on TCP port 24800: [root@prophead ~]# netstat -lpnt | grep synergy tcp0 0 0.0.0.0:24800 0.0.0.0:* LISTEN 3988/synergys If it isn't, try to start it as the desktop user--NOT root. If it won't start, figure out why first. Again, as the desktop user, you can try to start it like: /usr/bin/synergys -f That will start it in the foreground and should show you any errors it may be generating (or you can just check /var/log/messages for previous runs). Get those issues sorted first off. Most likely it's a typo in the config file, either $HOME/.synergy.conf (the first place it looks) or /etc/synergy.conf Note that if you're using "/etc/synergy.conf", make sure it has world- read privileges as the desktop user MUST be able to read it. Here's how I have them start up in my environment: "prophead" (F19, XFCE) is the server with the keyboard and mouse. In the XFCE config (Applications Menu->Settings->Session and Startup->Application Autostart tab), I have it automatically start the Synergy server using this command: /usr/bin/synergys (and I use a global "/etc/synergy.conf" file). On the clients (e.g. "golem4", my laptop), I have a similar autostart but the command starts the client: /usr/bin/synergyc -d ERROR 192.168.1.50 where 192.168.1.50 is the IP address of the Synergy server (prophead).
