#JUMP DESKTOP LINUX PASSWORD#
You only need to know your own user’s password and that user must be in the ‘sudoers’ group, which is basically the group of users which can use ‘sudo’ in the system. You don’t need to know the ‘root’ user’s password, in fact, probably nobody knows it or there is no password assigned to ‘root’. The sudo command will basically execute anything you want in the system as if the ‘root’ was doing it. So, how do you perform actions as the ‘root’ user? That’s what the ‘sudo’ command allows you to. Switch to root userįor security reasons, some systems have ‘root’ account blocked for direct login, either locally or remotely, so this means it will not accept someone who tries to log in using ‘root’ even with the correct password. Which makes sense because if you are going to switch to a user, you need to know the password of that user else it will be a security risk.
In the above example, you need to know the password of janedoe in order to switch to that user. In order to do this, there is a command “su -“, which allows you to switch to become another user: :~$ su - janedoe When using a Linux system you can log in with a user and then simply “switch” to another user through the same command line session. These are system administrators or users who can perform high-level tasks that can be considered critical or system dangerous. Each of these users might have or not different permissions or levels in the system which is given by the groups they belong to. These are the (human) users who can log in to a system. These are the users that are automatically created in Linux systems to be able to run services or applications and are not intended to log in to the system (in fact you can’t log in as any of these users). Who are these users? Where did they come from? I could write an entire article in regards of how users work in Linux, however, this is not the idea for this one.īasically, there are 3 types of users in Linux: 1. If you list all users in Linux, you’ll see a lot of users that you didn’t know about. To switch to root user in Ubuntu, you can use this command: sudo -i Various user types in Linux You can switch the users with this command: su – To switch users, you need to know the password of that user.
#JUMP DESKTOP LINUX HOW TO#
This all might sound confusing but, I will try to explain these so it can be easy to understand.įor the moment, here’s a quick summary of how to switch users in Linux command line. Not all users can execute all commands and not all users are allowed to switch to other users neither. Linux systems have different types of users with different types or permissions as well.
