Its a browser based interface for system administration of Linux developed by Jamie cameron. Web based administration was new concept in system administration. Many other tools such as Linuxconf, YaST and Redhat’s Gnome sysadmin etc replicated some of the functionality of Webmin but they couldn't make remote access easy. besides they can be run only at Linux box console as these are X-only applications. It supports multiple platforms. Following products have been released.

3. Webmin version 1.500 and Usermin 1.430 (fixes an XSS security & fixes
Webmin removes the need to manually edit Unix configuration files like /etc/passwd, and lets you manage a system from the console or remotely.
