Infrastructure

tb69 will be relocated to a new home without static IP

While login via ssh to start new jenkins slave agent would work with dyndns/via hostname, building on Mac also requires a graphical login for the build to work.
So if machine is rebooted, and jenkins agent is launched via ssh, builds will fail.
If however user is logged in graphically and then starts agent via jnlp (or ssh for that matter), all is well.

So feel free to do what is more convenient from your POV. requirements:

• way to ssh into the machine for tdf/jenkins-admin members to tunnel VPN for Mac's screen sharing (graphical login)
• either dyndns or VPN connection to connect.
