ssh tunnel from jump server

https://coderwall.com/p/tk_pwa/ssh-into-a-secured-host-through-a-jump-server-and-forward-ports

ssh -v -t -L 10443:localhost:20443 <jump_server> ssh -t -L 20443:localhost:443 user@<target_server>

ssh -v -t -L 9292:localhost:9292 cloud1@10.10.10.10 ssh -t -L 9292:localhost:9292 cloud10@192.168.48.110

simple tunnel

use -N to skip shell

ssh -T -f -N -L 31808:localhost:31808 user@10.10.10.10

reverse tunnel

https://unix.stackexchange.com/questions/46235/how-does-reverse-ssh-tunneling-work/46271#46271

ssh -f -N -T -R22222:localhost:22 user@10.10.10.10

This tells your client to establish a tunnel with a -Remote entry point. Anything that attaches to port 22222 on the far end of the tunnel will actually reach "localhost port 22", where "localhost" is from the perspective of the exit point of the tunnel (i.e. your ssh client).
