3. Configure Webmin Users
3.1. Introduction
This chapter familiarizes the user with:
• Configuring Webmin users
• Displaying and removing existing login sessions
• Setting up password restrictions
3.2. Webmin User and Group Fundamentals
When the Webmin package is installed for the first time, an account for the user: "root" exists on the
router. Besides the root account, three groups, or privilege levels, are defined: "admin", "operator",
and "guest".
• Users belonging to the "admin" group have full access to all Webmin modules.
• Users belonging to the "operator" group have full access to most Webmin modules with the
following exceptions:
• Webmin Configuration
• Webmin Event Log
• Webmin Users
• Scheduled Commands
• Scheduled Cron Jobs
• System Hostname
• System Time
• SSH Server
• Backup And Restore
• Upgrade System
• Upload/Download Files
• Users belonging to the "guest" group can only view configuration and statistics but can not
change them. Besides this limitation, they also have no access to the modules forbidden to the
"operator" group, listed above.
The "root" user must always be defined. New Webmin users can be created and deleted, and must
belong to one of the three aforementioned groups. New Webmin user names must contain only the
characters "a-zA-Z0-9-.@" but must not begin with "@" and must not conflict with any existing user
