The password would be whatever the root password is set to.
su (will change user to root)sudo command (will run command as root)
When it askes for user enter root, and then when it asks for password enter the password. If you don't know password for root it's a really serious problem. You can also log in as root via command line by typing "su"
This will depend on the distribution. Most Linux distributions allow you to assume root by simply entering "su", followed by your password. Ubuntu-based distributions disable the root account by default, and you are expected to use the "sudo" command before any command that requires root privileges (ie. sudo rm -rf /). You can gain a root shell by entering "sudo su", followed by your password.
In Linux and Unix-like systems, the "root" account is the only account with all possible privileges. The "root" password would be the password needed to access this account or assume its identity.
The square brackets indicate that the enclosed item is optional. Thus, the simplest way to use the su command is to just type: su The operating system assumes that, in the absence of a username, the user wants to change to a root session, and thus the user is prompted for the root password as soon as the ENTER key is pressed. This produces the same result as typing: su root If the correct password is provided, ownership of the session is changed to root.
Run the command "passwd". You will have to enter your old password to change it. If you are root, you will not have to enter the old password to change a user's password.
Try "root" as the username and "uClinux" as the password.
The Linux superuser is called "root." There is very little root cannot do. This is why it is a Very Bad Idea to do anything as root unless absolutely necessary. Use sudo instead with commands that need it.
Depending on the distribution, you should either use "sudo" preceding the command, and then enter your password, or first enter "su"to become the root user.
Linux Mint, like Ubuntu and most other Debian-based distros, do not enable the root account by default. If you need root permissions to do something, enter the commandsudo [whatever program you want to run]and enter your password when prompted.
There is no command specific to SSH. Whether you are physically using the machine in question or using an SSH client the process is the same. On Ubuntu, one is encouraged not to use the root account directly. To execute a command as root, enter sudo . On distros that don't include sudo, you can gain a root shell by entering the command su root. Both commands will require you to enter either your admin password or the root password, respectively.
No, none of the passwords used in a Linux system can be "recovered" because there isn't a reverse encryption for it. However, you can "reset" the root password by using the single-user mode at boot time (which puts you in the root account automatically) and then changing at that time.
