SSH Reverse Tunneling

1. Start a SSH Server on you local machine.

2. Someone with cu access must do:sh -fN -R 7090:localhost:23 keerthi@your_public_ip

   • -f: Fork to background # I think we can drop this flag
   • -N: Dont execute any command
   • -R: Do port forwarding This will bind 7090 on your machine to 22 on the CU.
