linux - Script for merging two SSH connections together? -


i'm trying write bash script merge 2 already-existing ssh connections.

for example, if have embedded device automatically creating ssh connection server (from behind firewall), how can connect server in middle, , jump already-existing connection embedded device?

i have looked possibility of using server 'jump host', seems need reliably determine (and send ssh requests) embedded device?

i have looked @ having embedded device create 'screen' on remote server , connect that, seems operating on remote server.

i'm sorry if wrong place ask this, don't know else ask.

it sounds requirements going need either upnp solution or tunnelling solution through firewall. following link discusses reverse ssh tunneling 1 part of solution.
