Webmin is a web-based interface for system administration for Unix [including Linux]. Using any browser that supports tables and forms (and Java for the File Manager module), you can setup user accounts, Apache, DNS, file sharing and so on.What is Usermin?
Webmin consists of a simple web server, and a number of CGI programs which directly update system files like /etc/inetd.conf and /etc/passwd. The web server and all CGI programs are written in Perl version 5, and use no non-standard Perl modules.
Usermin is a web interface that can be used by any user on a Unix system to easily perform tasks like reading mail, setting up SSH or configuring mail forwarding. It can be thought of as a simplified version of Webmin designed for use by normal users rather than system administrators.
Like Webmin, Usermin consists of a simple web server, and a number of CGI programs which directly update user config files like ~/.cshrc and ~/.forward. The web server and all CGI programs are written in Perl version 5, and use only the non-standard Authen::PAM perl module.
