Linux systems administrators have many tasks on their plate. One such task is user administration, which can range from creating users, modifying users, locking users out of their accounts and deleting users. Along the way, Linux systems admins will also find themselves having to troubleshoot user accounts when problems arise. Without the necessary skills to take on these tasks, a Linux systems admin will have a hard time keeping up with user requests.

Jack Wallen, writing for TechRepublic Premium, is here to give you a helping hand. This guide will walk you through the process of creating a user account, all the way to deleting that account.

SETTING PASSWORD POLICIES

Out of the box, your users can set any password they want. You might set them up with a password of “%uIUK8*12OPf,” but when the user logs in, they could use the passwd command and reset their password to “password” or “12345.” You don’t want that.

Setting a user password policy on Linux isn’t as easy as you might expect. First, you must install libpam_cracklib. On Debian-based distributions the command is:

sudo apt-get install libpam-cracklib -y

There’s no need to install any software on RHEL-based distributions.
