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!

Best off configuring sudo for that user (with no password) and make sure that user has !requiretty in the sudoers configuration.

Does "ssh -t" help?
YESS. It prevents the tty error from showing up and asks me for a password as expected. BUT, how do I then automate the entering of the password?
John Kennedy mentioned using expect which I've used before but found it to be 'finnicky'. I may have to look at it again...
Changing settings such as sudo configuration or ssh config may be daunting since I have a large number of systems(150+) that would need to be modified. :-/
