Q.I have just installed Ubuntu Linux. But, what is the default root password? I can only login as a normal user.
A.This is the mystery for most users-you didn't set a root password, so what is it?
The root user can do anything as this A/C has full access to system. So using root account for daily work can be dangerous.
To be frank root A/C is locked by default under Ubuntu Linux. Therefore, you cannot Login as root or use Su-command to become superuser.
To run all administrative command use sudo command. sudo allows a permitted user to execute a command as the superuser or another user. ubuntu setup your default account (the one created during installation) to run all administrative commands.
For example create a new user called bar, you need to type sudo command as follows:
$ Sudo adduser bar
Password:
When sudo asks for a password, it needsYour ownPassword; this means that a root password is not needed.
Here are few more examples.
Task: start/stop/restart services stored in/etc/init. d/directory
$ Sudo/etc/init. d/ssh stop
$ Sudo/etc/init. d/networking restart
Task: Avoid typing sudo each and every time
Note that this is not recommended until and unless you are an expert and aware of what you are typing:
$ Sudo-I
Above command will start/bin/Bash as a root shell so that you can enter a root user command W/O using sudo.
