ssh -R 2222:localhost:22 linse@linse.me

The local user would open a tmux session specifying a shared socket:

tmux -S /tmp/pair new-session -s pairing;
chmod 0777 /tmp/pair


Other guest user goes back into the tunnel like so:

ssh -p 2222 -l linse localhost

The guest user connected as pair would attach using the shared socket:

tmux -S /tmp/pair attach-session -t pairing
