Synergy – share mouse and keyboard across network

Looking for a cross platform network  mouse sharing program (KVM) I came across synergy:

It works well, but I did run into a less than obvious configuration issue –
initially once I’d installed it on a PC (with the mouse) and a Macbook (as client),
the Macbook couldn’t connect.

These messages appeared in the log:

Warning: Unrecognized client name “XXX”, check server config


It turns out you need to add the hostname of any connected computer in the settings page,
by dragging the screen icon from top right onto the grid somewhere next to your main screen:

and then it’s important to rename it to match the client ‘s hostname, otherwise you’ll get the same errors as above.

Once that’s done it works great, and I’m now able to share the same mouse across multiple computers just by moving the mouse off the edge of each screen.
