Alternate shell behaving strangely

Question

I set up my default shell on ubuntu to be sudosh2 instead of the default /bin/bash.

Now when I ssh into the account, I get some presumably bare-bones shell behavior (only $ prompt, arrow keys result in ^[[D, etc.)

What does that mean, and how do I get a normal bash shell to load, without having to manually start /bin/bash every time I ssh in?

Answer 1

What you're seeing is the /bin/sh shell, which never supported arrow keys or other such features in the first place. Its default prompt is $.

Edit the "default shell" parameter in /etc/sudosh2.conf to launch bash instead.
