I've painted myself into a corner:

My machines each have only sudo user which is local to the machine. I setup an autofs to mount over top of /home; the mount does not include a folder for the sudo user.

I can't log in to the machines to change the sudo user's home directory, nor add a different user (who does have a /home directory to the sudo group).

Is there any way to execute a command over ssh without having a home directory. Alternatively, I can log in as a non sudo user, so is it possible to execute a command using su without a home directory?

  • Does ssh user@host dash work? It should say nothing and wait for input, after which you can run ls to see if commands work. If that works, you can try sudo echo hi to see if sudo is working. – Chai T. Rex Jan 27 '18 at 0:04

  • Does it sit there waiting for input after the welcome message? If so, try sudo echo hi. – Chai T. Rex Jan 27 '18 at 0:09
  • No, it immediately closes the session. – sheridp Jan 27 '18 at 0:12
