I am using Ubuntu 8.10: cd ~/workdir/filesys sudo chown -R root . sudo chown -R <username> opt and got some warnings and errors: Starting OpenBSD Secure Shell server: sshd@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ WARNING: UNPROTECTED PRIVATE KEY FILE! @ @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ Permissions 0664 for '/etc/ssh/ssh_host_key' are too open.

And I change the owner of the folder ~/workdir/filesys/etc/ssh to <username>: sudo chown -R <username> ~/workdir/filesys/etc/ssh And then reboot, and got only error: Starting OpenBSD Secure Shell server: sshd/var/empty/sshd must be owned by root and not group or world-writable. failed (255: ). This message is the same as I gave before, and I can not login as root user: 192.168.1.105 login: root Login incorrect 192.168.1.105 login: root Login incorrect Can anyone please help me ?

This especially happens if you switch between root and <user> frequently. Try chowning the rootfs to the appropriate user once again. Hope this may land up in some clue.

I tried to open file /etc/passwd and /etc/shadow and sure that the root user has no password.
