I am trying to setup SLES10 to prevent direct login as root on the 3270 console for a SLES10 Linux guest. Terry; In order to do this, you need to remove or comment the entry for ttyS0 in /etc/securetty. It doesn't seem like a good idea in practice, though I couldn't put my finger on

This was my first thought also, but on second blush, if you have properly set up sudoers, then being able to log in as your own userid, listed in sudoers, is sufficient, and you shouldn't need to log into root from anywhere, in theory. The downside of this theory comes in the form of certain

My mistake here. I am not preventing direct root login on the 3270 console. Any ID you enter on the 3270 console including root allows for no password or incorrect password. I am thinking I must have something not set correctly in one of the /etc/pam.d files ? Any thoughts ? TIA
