Are you able to restart the box? If you have KVM access, you could restart it into single user mode (assuming it has not been disabled) and work from there

Hey thanks for your reply, I did restart the box, but once I open the console it does asks me for login/password

[therealidiot]

Can you send ctrl+alt+del through the kvm? if so, maybe this will cause it to restart so you can access the bootloader

[etuil]

Yes I was able to go trough and edit the kernel thanks a bunch, I thought I was in a bigger trouble!

[angdis]

OK, but what can you do after you get in through the bootloader?

[etuil]

If you are not able to boot it into recovery (could ask you for root password) you need to edit the kernel by editing "ro" (or "ro quiet ..." something) and changing it to rw init=/bin/bash .. than boot up by pressing [ctrl]+x and voila from there just change the root password via "passwd root" restart and ta daah root password changed

[therealidiot]

Add "single" to the kernel command line
