Linux Systems Management
The practice of remotely monitoring and controlling Linux users and machines on a network from a central place is known as Linux management. Because of its ease of installation and use, Linux is quickly becoming a popular alternative to traditional operating systems in businesses today. Linux provides greater customization options, and the fact that it is an open source operating system is one of the primary factors pushing its popularity.
The following are some of the standard Linux Management features;
- Scan systems on a regular basis to get comprehensive hardware and software inventory information.
- Software licenses, compliance, and warranty information may all be managed.
- Hardware and software-specific events are alerted through email.
- Patching the Linux operating system and third-party software may be done automatically.
- Audits and reports on patch compliance.
- Execute custom scripts as settings to automate time-consuming administrative operations.
- Patches and software can be installed or uninstalled as needed.
- Display messages to the folks you want to reach.
- Using Active X and HTML5 Viewer, you may remotely access machines on your LAN and WAN.
- Before granting access to a remote desktop, the user is asked to authenticate their identity.
Importance of Linux Management
- It improves maintenance.
- It improves security.
- Supporting users when their system fails is easier.
- It ensure that each user and their machine have the appropriate programs and configuration settings with effective system administration.
- Helping users to solve their issues quickly.
Install and Use Usermin on Ubuntu 20.04 | Debian 10
In this guide, we will focus on the installation and use of Usermin on Ubuntu 20.04 and Debian 10. Usermin is a web interface application that allows any user on a Unix system to accomplish tasks such as reading mail, establishing mail forwarding, setting up SSH and many more. It’s a stripped-down version of Webmin that’s intended for regular users without always system administrators. Usermin, like Webmin, is made up of a basic web server and a set of CGI scripts that update user config files such as
/.forward. All CGI scripts and the web server are built in Perl 5, and only the non-standard Authen::PAM perl module is used.
Features of Usermin
Below are the cool features of Usermin;
- Scheduling commands to run at certain period of time.
- Scheduing cron jobs.
- Through System Documentation, you can search manual pages, package documentation e.t.c.
- Ability to set your Usermin preferred language.

- Protecting web directories.
- Using MySQL Database Server to configure MySQL database server’s databases, tables, and permissions.
