I screwed up sudoers and I haven't root access (remote server).
 

This is the hard way to learn when you MUST use visudo, specially in a remote server. That's right. I did something stupid like:

and now have:

So what if I have locked the root account (passwd -l root) and now I can't do su to fix sudoers file???

As i said this is in a remote server (VPS) so I can not use recovering special tools via CD or similar.

thanks.-

no recovery mode or something like that?

the thing is that it supposed to be nothing that you can do if you do not have recovery terminal.

You can boot from a recovery or live CD and try to fix the file. This should give you the idea: http://www.howtoforge.com/how-to-res...d-with-knoppix

???not really helping.

Thanks for your answers.
Yes, I do not have physical access.
I am thinking in trying code some simple routine (as I have ssh access as user at least ) using something like http://www.kernel.org/doc/man-pages/...etpwent.3.html
Obviously I am not hurry and may be fun. Any idea to start?
Thanks.-

Update
 

What a odyssey! I was thinking in very rare things to solve this.

Solution:
I have webmin installed. So as the root account WAS :) locked, I have another webmin user with access to all modules.
Webmin > Users and Groups > root account > password: No password required

Can you believe it?

no. thats too much luck for you :-D

Why? He could boot from a live system, mount his hard drive and then try to fix /etc/sudoers.
