Software center

NethServer is highly modular. At the end of the installation a bare minimum set of modules are ready to be used. The basic system includes modules like network configuration and log viewer. Additionally, the administrator can install additional modules, like Email, DHCP and PXE server, Firewall and gateway

The Available tab lists all of the modules that can be installed. This list can be filtered by category.

To install a module, check the corresponding box and click on Add. Some modules suggest optional packages that can be installed whether at the same or at a later time.

To install optional packages at a later time, select Installed tab and push the Edit button on a listed entry.

To remove a module, push the Remove button.


When removing a module other modules could be removed, too! Read carefully the list of affected packages to avoid removing required features.

Software updates

Updates for the installed software are listed under the Updates tab. A message appears when software updates are available.

Updates released from upstream (CentOS) are automatically available on NethServer. On every minor release of CentOS, for example when updating from 7.3.1611 to 7.4.1708, a banner is shown inside the Software Center to inform the user about the new release.

Even if upstream updates can be considered safe, users should check Community forum (, to be informed about new changes.
