How to bring back/restore root account?
Hi all,
I have a problem, when I use script with 'expect', accidentally I was deleted root account by "userdel root". Unfortunately, it works, because no other root user login on it. Solaris document said that root cannot delete root, but in my case it works because it deleted by script, not physically log in.
My question is: how to restore my root account? I can log in using other account, but not root and no other account have privilege as root.
Any help would be appreciated. Thank you
Regards,
Joash
