I have a situation that isn't ideal as far as security and work is concerned, but the idea is that I have to connect to a server via another, I can't store keys anywhere and I have to do varying stuff in the inner shell. So after some tinkering I got this to work:

sshpass -p"mypass1" ssh mxd 'sshpass -p"mypass2" ssh -t 10.10.10.10 "cd /path/to/work; /bin/bash -i"'

So the cd is done and I can type and execute commands in the inner shell.

As this isn't really readable I tried to improve it with heredoc:

sshpass -p"mypass1" ssh mxd bash <<EOF1 sshpass -p"mypass2" ssh -t 10.10.10.10 bash <<EOF2 cd /path/to/work /bin/bash -i EOF2 EOF1

The thing is that it performs the cd (the prompt says so), but then immediately exits both ssh. The goal is that equally to the first snippet I can enter commands in the inner shell. What am I missing here?

  • Doesn't the jump host functionality built into open ssh provide this, but much easier and securely? Commented Dec 26, 2022 at 23:49
  • @MarcusMüller I need to send the password through, so as far as I understood jump hosts they are no option for that. Commented Dec 27, 2022 at 0:01
  • You misunderstood that, then. In a ssh jump host, that is unproblematic. Commented Dec 27, 2022 at 9:05
  • @MarcusMüller I'm not sure what I should do with your post. If you know how I can squeeze a password into a jump host, feel free to tell me. Commented Dec 27, 2022 at 22:18
