Is this a trap? I made these steps in FreeBSD 10:
1) ssh as root prohibited
2) logged as user
3) su as root
4) as root chsh changed name of user "user" to "luser"
5) exit from root
And from this moment I can't su root cause the luser is not in the wheel group and I can't change group in /etc/group because I have no privileges for doing that.
What can I do to login as root ?
