SSH execute remote command (with jump)
Hi all,
I am facing the following issue:
Host A should execute a remote command (say pwd) on host B2.
B2 is not directly reacheable but you have to connect from a to B1, then from B1 you can execute the command ssh user@B2 pwd.
B1 and B2 are directly connected:
A => B1 => B2
| ^
|____pwd__|
Is there a way to use ssh from host A + single command to do the work?
Thank you very much for help.
Evan
