I have set up my server to allow key/pair authentication by following instructions similar to what is found in this post.

As far as I can tell that is working correctly. If I do the following, for example, it works correctly:

ssh [email protected]

It will NOT prompt me for a password. This is what I want to happen. However if I write a small bash script like this:

#!/bin/bash -x
ssh [email protected]

and execute with:

sudo ./mytestscript.sh

...it will prompt me with:

[email protected]'s password:

What am I doing wrong? I need to be able to login from within my script without being prompted for a password!
