Usermin User Tool
Usermin is a web-based interface that allows users to manage various aspects of their UNIX/Linux accounts. It provides functionalities like changing passwords, managing email filters, viewing emails, and editing files through an easy-to-use GUI accessible via web browsers..
Usermin Overview: Usermin is a component of the Webmin suite, specifically targeting normal UNIX/Linux users instead of system administrators. Running primarily as a standalone web server (using Perl), it listens on port 20000 by default. Usermin offers modules for email management, file editing, password changes, and more, providing users autonomy over their accounts without direct shell access.
Default Port & Protocols: Usermin generally operates over HTTP on port 20000. It is configured to allow or enforce HTTPS for secure communication, though by default it might not be encrypted. The tool doesn't rely on TCP or UDP transport layer services in the strict sense; it uses SSL over HTTP protocols embedded in its own web server stack.
Deployment Details: Usermin is designed for simple deployment, often bundled with Webmin or installed separately. Access is managed through the UNIX/Linux PAM or shadow password files, integrating seamlessly without extra backend services. Customizable modules enable extensions and granular control for various site-specific needs.
