You can download the binary for synergyc (the client) at http://saunby.net/770/synergy.tar.gz

Execute as

./synergyc -f ip_of_server

You'll need to have the synergy server running on your PC first.

See http://synergy2.sourceforge.net/running.html

Note that the return key behaviour isn't useful, use enter on the numeric keypad, or on my laptop it's Fn + return.

I'm using fixed IP addresses for everything on my wireless network. If you use DHCP then things might be a little awkward.
