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.

You would probably be better off setting up forced-commands-only only login for root. and configuring the /root/.ssh/authorized_keys file with the command you want to execute.

Maybe try /etc/securetty
