Every page in Webmin shows your system's hostname and operating system in the browser status bar by default. To have it shown elsewhere or turn it off altogether, select one of the following options from the
Display login and hostname menu:
At bottom of browser
The information is shown in the browser's status area, which is usually at the bottom of the window.
In browser title
The information is added to the title of each page, which usually appears in the browser window title.
Above page heading
The information is shown above the title of each page.
Nowhere
The hostname and operating system information are not shown anywhere. If you are worried about untrusted users learning too much about your system, this is the option to choose.
