-Again, please make sure you install from within Webmin (Un-used Modules) then Refresh Modules to move the BIND link under ServersThis is the default screen.+This page includes a very brief overview of Webmin module screens, before turning the instance into a Tier-2 service stackThe page is going to grow and expand as feedback comes in for better, more detailed explanationsIf you are already familiar with Webmin, or you do not wish to use it you may skip this page entirely.

 In the upper left corner the icon that looks like a gear is the Module Config. In the upper right corner the icon looks like a "Play" button starts the service. When you configure RDC a "Refresh" button is added. Do not yet start it, but lets look at its home directory. In the upper left corner the icon that looks like a gear is the Module Config.

 ==== Network Security ==== ==== Network Security ====
-Debian does not assume anything about the purpose of the system, and does not install or configure additional software, and it does not start services by default. //iptables// is an exception to this, it is installed by default. However, it is left unconfigured and it is not started. If you installed a firewall software such as FirewallD - iptables is going to be started and managed by that software.+Debian does not assume anything about the purpose of the system, it does not install or configure additional software, and it does not start services by default. //iptables// is an exception to this, it is installed by default. However, it is not configured and it is not started. If you have installed a firewall software such as FirewallD - iptables is going to be started and managed by that software.

-More to come+If you start iptables with a wrong configuration you might lose access to your instance! 
 + 
 +==== Webmin Modules ==== 
 +Some modules in Webmin are matured and well-rounded - the BIND module, for example. Some are obsolete, no longer maintained, and these days they are only included for backwards compatibility - such as the Jabber IM Server. Some are mature and install from within Webmin, some needs to be installed from the shell and tell Webmin to look for them "Refresh Modules".  
 + 
 +{{:opennic:setup:webminbind:base-008.png|Module installation}} 
 +Webmin has good support for FirewallD - but it must be installed from the shell. 
 + 
 +==== Logging ==== 
 +Webmin provides access to several logging facilities, with management for logging added for BIND and for Webmin. 
 + 
 +{{:opennic:setup:webminbind:base-009.png|The standard UNIX logs }} 
 +Security starts with these logs, as nearly all attacks leave some clues in these logs. 
 + 
 +==== Conclusion ==== 
 +You may write your own scripts and use a tool such as Ansible to do more, better than what Webmin does. However, Webmin makes your instances much friendlier inside an environment without Information Technology professionals expert with GNU/Linux. On a factory floor, for example, Webmin is able to serve engineers, managers, production workers with much less training than full-featured but more complex tools.
