= Webmin [[PageOutline]] Webmin is a program that provides a web user interface (webUI) for Linux and Unix systems. Using this interface a wide range of different tasks can be performed such as console access, viewing system information, managing the network interfaces or a firewall, along with many others. For more details see the official Webman Wiki introduction page: https://doxfer.webmin.com/Webmin/Introduction [[Image(Venicewebui.png,600px)]] == Video Overview A video overview of the contents of this page can be found here: https://youtu.be/_gZPoB-k6dg == Requirements Getting started with Webmin will require the following things: * A Gateworks SBC with Ubuntu Focal installed. Ventana, Newport, and Venice are all acceptable choices. * A Desktop workstation on the same subnet as the SBC. * An internet connection. * Optionally a browser that supports Java (some modules require this). = Installation for Focal Ubuntu: Copy these commands into your console, this can be done as one full block. {{{ wget -qO - https://download.webmin.com/jcameron-key.asc --no-check-certificate | apt-key add - sudo sh -c 'echo "deb http://download.webmin.com/download/repository sarge contrib" > /etc/apt/sources.list.d/webmin.list' sudo apt update sudo apt install webmin -y }}} == Connecting to the Web User Interface On your workstation navigate to !https://:10000/ '' For example !https://focal-newport:10000/'' The default login credentials are, username "root", password "root". == Troubleshooting If the webmin webUI is not available check the service manager: {{{ systemctl status webmin }}} Error output can be accessed by executing: {{{ /etc/webmin/start }}} = Navigating the UI On the top left side there are two tabs "Webmin" and "Dashboard". "Dashboard" displays system information, the "Webmin" tab contains selections for accessing modules, you will see the tab automatically switch when a submenu is selected. The "Webmin > Webmin" menu contains options for configuring Webmin, such as menus to update the password, change the theme, or use a different language. Other Webmin servers can be added and accessed through the "Webmin Servers Index". ** Note: ** To add a server the "hostname" field should only contain the $HOSTNAME not "http" or any other superfulous information. = Webmin Modules Webmin has over 100 modules that can be used, for more details please reverence the Webmin_Modules wiki: https://doxfer.webmin.com/Webmin/Webmin_Modules If you would like to add a module select "Un-used Modules" then the module you would like to install.
