Greetings All-

I'm about to embark on some remote management testing and need a way to login to a remote system running CentOS 4.x/5.x via SSH, su to root (using a password), then execute a command.

I currently login to the boxes using key based SSH like this:

ssh -i ~/remote_key admin@$REMOTEIP

Then, I SU to root. However, if I try to do this automatically like this:

ssh -i ~/remote_key admin@$REMOTEIP 'su -l'

I'm getting:

"standard in must be a tty"

So, how am I able to remote login using SSH, su to root, then execute a command as root?

All comments and suggestions welcome. Thanks!
