# generic version
ssh -R <remote_port>:<local_interface>:<local_port> <remote machine>

# example (dev is a host configured in ~/.ssh/config)
ssh -R 4567:localhost:4567 dev

# Ubuntu hosts require an extra step of config

# (run on server)
sudo echo -e "Match User scott\n   GatewayPorts yes" >> /etc/ssh/sshd_config
service ssh restart
