How to instal a printer
Step 1: Configure Lliurex Update to automatically download driver software
Look for a change of the device installation in Lliurex and click on the
Change the installation settings of control panel devices option in the
results list.
The Device Setup Settings window appears.
Step 2: Connect your printer to your computer
Connect the printer to the computer using a USB cable or through its red
local so that Lliurex can detect the printer during the installation of
the printer driver.
Step 3: Install the printer driver with the
Add Printer Wizard
Select the connection type of your printer and use the wizard. Add a Lliurex printer to install the embedded print
driver.
Step 4: Print and scan a document
Try printing and scanning, depending on your printer's resources, to
make sure the printer is working.
If you can print and scan, the driver is installed.
How to create users?
The
command useradd allows to add a user indicating as parameters the
particular information to create the user in the same line of commands. The syntax is:
// Create user
Useradd [options] usernameAmong the most outstanding options we have:
-g: Main group that we want the user (must exist previously)
-d: User's home folder. Usually this is / home / username
-m: Create home folder if it does not exist.
-s: User shell. Typically it is / bin / bashExample: If you want to create a user named 'pedro' whose main
group is 'teachers', whose home folder is / home / pedro and its shell
is / bin / bash, execute the following command:
// Create a user
Sudo useradd -g teachers -d / home / pedro -m -s / bin / bash pedroIn this way we will have created the user Pedro and his home folder. If we do not use the -m option, the user's home folder will not be created; In which case we would have to create it manually. We will only have to set your password with the command passwd:
// Set the user password
Sudo passwd pedroThen the system will ask us twice the password that we want to assign to Peter.The useradd command allows you to create many users automatically using scripts.It
is recommended that the user name be lowercase and in addition to
letters can also contain numbers and some sign like normal hyphens and
underscores. We must remember that unix is case-sensitive, that is, Pepe is different from pepe.
