I installed a Ubuntu and it only has a user. I can login to the system without login. It doesn't ask me for un/pwd. but when I am in, and I want to run some commands as root (sudo), it ask for password and not allowing me to run it. No password works. How can I find password for this user or root?
I have Ubuntu 12.04 LTS installed and have read many articles on finding a way to change the admin password as i forgot it after installing it a while ago. I have 2 users on this comp which i know the pass to 1 but the admin 1st user i can no longer get into. I have tried many ways like going through grub, root and trying to unmount.
I've ran a yum update on my CentOS 5.8 box and now I am unable to log into the console as root. Basically what happens is I receive the login prompt, enter the correct username and password, and am immediately spit back to the login prompt.
Hello cPanel peeps... I encountered a strange problem with the root user login and password.
Steps before problem occurred:
1. I enabled PHP-GD on my server through the Apache configuration in WHM and let WHM rebuild the configuration (took longer than usual).
2. After a long period, I restarted httpd and the server. When it came back online the root login and password did not work.
I can login to my machine (FreeBSD 9.1-RELEASE) for any user (for example: root or operator or any that exists in /etc/passwd) with any random password that I type... I tried to reset password for root with passwd, but again if I try to login I can login with any random password that I type in... strange. This ONLY works when I login directly from tty.
