reset the Synergy 1.x server and client processes after sleep/wake

## this runs on the Synergy *server* Mac and assumes the *client* is connected via bridge0
## server: 169.254.168.87 ; client: 169.254.168.86
## use e.g. ControlPlane to run the script on wake
## brew install terminal-notifier
## use ssh-copy-id to enable passwordless ssh from the server to the client
## add to /etc/sudoers.d/youruser e.g. $YOUR_USER ALL=(ALL) NOPASSWD: /usr/bin/killall,/sbin/ifconfig
## replace $YOUR_USER with your username on the client
