I believe you can get in with single user mode. Just reboot the machine and when it is about the go into the second phase of the boot process stop it by hitting anything Enter. The enter the following command. -- boot -s -- This will take you into single use mode. When it gets further along it will ask you for a shell. Use the default, which I think is /bin/sh. Next you next to get the filesystem up so you can edit the files. Maybe this part is options since you are editing files in /etc, but I would do this just to be sure. -- fsck -p mount -u / mount -a -t ufs -- Then edit the password file as you did before and be sure to get the correct shell. For me, I leave the root shell alone and create an alternate root user called rootb. I set it to the shell I want and the home directory that I want with all of the settings that I want. The user id is still 0 and I am still effectively root as that user. I can perform any root functions. I originally did this when I was one of two sys admin and I preferred the bash shell while the other sys admin liked csh. It is also nice to have backup root account in case you mess one up, especially for remote adminstration.
