You mention copying securetty over, but this problem has got to be something like that. Something in that install is preventing root logins. Check the logs for clues. It's not going to have anything to do with UML itself. Jeff |

rookie observation, but do you have root access enabled in /etc/ssh/sshd_config?

The file /var/log/messages has the following: login: FAILED LOGIN 1 FROM (null) FOR root, Authentication failure I guess that's why I couldn't find an entry for /etc/securetty that would work, but why am I getting (null) instead of a tty device (the downloaded Redhat 6.2 image shows login: ROOT LOGIN on 0). Of course, deleting /etc/securetty fixes the problem too but I don't want root logins via telnet exposing the root password.

I've tried several different devices: tty0 tty1 tty2 tty3 vc/0 vc/1 vc/2 vc/3 ttys/0 ttys/1 ttys/2 ttys/3 I'd be happy to try more, but none of the other devices seems apporpriate.

I finally got it to work with the following entries (courtesy of the devfs FAQ): 0 1 2 Now I'm wondering why these are needed for my system but not the Redhat 6.2 filesystem I downloaded. The FAQ also mentions an updated util-linux package but both filesystems have the same package install (util-linux-2.10f-7). Even after updating my util-linux package the problem persists. Any ideas?
