SSH setup for remote pairing

If Animal and Fozzie wanted to pair on Animals machine and they both have access to shared.muppets.com then they could use the following setup

• Animal will have the following in ~/.ssh/config

Host tunnel_from_muppets
  Hostname space.muppets.com
  RemoteForward 1235 localhost:22
  User animal

• Fozzie will have the following in ~/.ssh/config

Host tunnel_to_animals_via_muppets
  Hostname space.muppets.com
  LocalForward 9999 localhost:1235
  User fozzie
   
Host animals_via_muppets
  Hostname localhost
  User fozzie
  Port 9999

• Animal creates an ssh tunnel to his machine via shared.muppets.com

ssh tunnel_from_muppets

• Fozzie creates a tunnel to Animals tunnel on shared.muppets.com

ssh tunnel_to_animals_via_muppets

• Fozzie in another shell can then ssh to Animal's machin as follows

ssh animals_via_muppets

What an amazing gist.

An addition that we've found useful is to also forward the rails server to port 3100 on the client's machine:

Host animals_via_muppets
  Hostname localhost
  User fozzie
  Port 9999
  LocalForward 3100 localhost:3000

This may require you to edit /etc/sshd_config and set PermitTunnel yes (at least on OSX)

Perfect. No need to open a port on the router, thus leaving my dev box open to attack.
