In this post, i will show on how to enable root login in Ubuntu 11.10 linux server. This post assumed that you already installed Ubuntu 11.10 server. Besides, that is assumed i had created the username ‘ehowstuff’ on my previous installation of Ubuntu 11.10 server and login to this Ubuntu 11.10 server as ehowstuff account.
login as: ehowstuff firstname.lastname@example.org's password: Welcome to Ubuntu 11.10 (GNU/Linux 3.0.0-12-generic-pae i686) * Documentation: https://help.ubuntu.com/ System information as of Tue Apr 3 20:57:51 MYT 2012 System load: 0.11 Processes: 66 Usage of /: 6.5% of 13.50GB Users logged in: 1 Memory usage: 3% IP address for eth0: 192.168.1.37 Swap usage: 0% Graph this data and manage this system at https://landscape.canonical.com/ Last login: Tue Apr 3 20:54:22 2012 To run a command as administrator (user "root"), use "sudo
". See "man sudo_root" for details. ehowstuff@ubuntu11:~$
To enable the root login and create root password, please enter “sudo passwd root” on the terminal. Then you will be asked to enter your login password (in this case i login as ehowstuff), followed by the password of ROOT account (enter new UNIX password).
ehowstuff@ubuntu11:~$ sudo passwd root [sudo] password for ehowstuff: Enter new UNIX password: Retype new UNIX password: passwd: password updated successfully
After this steps done, you can then directly log in as root either through putty or terminal.
