Install and configure modules in NethServer


It is our last tutorial of NetServer’s series. In our previous tutorials, we discussed how to

Today, we will see how to use Server-manager, the web interface for NethServer and how to install different modules.

Getting started with NethServer’s Server-manager

First log in to NethServer’s dashboard using URL: https://Nethserver_IP_Address:980/

If you installed NethServer using ISO image, login to web interface using the following username and password.

  • Username – root
  • Password – Nethesis,1234

If you installed NethServer on top of CentOS minimal server, you can log in as root user and its password (The one you provided during installation).


The NethServer’s Dashboard will look like below.

The first thing you should after logging into the server-manager is to change your root user password.

To do so, hover mouse pointer over the root user account on the top right corner and click Profile. Then, click Change password button to change the root user password.



Enter the current password followed by new strong password twice with combination of special characters, numbers, small and capital letters.

Click Submit after entering the new password. Log out and log in back with new password.

Let us go back to dashboard. The dashboard has three sections.

  • System status – Displays NethServer’s details
  • Services – Displays the running services
  • Applications – Displays the installed applications

System status section displays the NethServer’s system details such as;

  • NethServer’s version
  • Kernel details
  • Memory usage details
  • Date and time
  • Uptime
  • Disk usage
  • Network card details
  • Software RAID details
  • Hostname, domain, gateway and DNS etc.

Disk usage:

This section visualizes the disk usage in different colors. Double click and Click on each color to browse the different directory trees.

Log viewer:

All logs can be found here. Click on the log file to view the log details.


In this section, you have options to power off or reboot the NethServer.

Software center:

This is the important section. In this section you can install new modules, update, and remove an installed module etc.

Network services

In this section, you can configure the network services for different zones. The zones are distinguished by separate color. The green color represents the local area networkblue represents the guests network, Orangerepresents DMZ networks, and red represents the public networks.

You can edit and define the service whether it should be accessed from a specified zone or not.

Password policies

You can define or adjust the password polices for users.


You change the default port of SSH here. I recommend you to choose a random number for SSH port which is hard to guess.

Also, you can allow or disallow SSH access for root user.

Trusted networks

This section shows the trusted networks. You can also have option to add a new trusted works.

As you can see in the above screenshot, Trusted networks are in green zone. So, Hosts in the trusted networks can access the Server-manager, and Samba shared folders.


Here you can set DNS server details (Primary and secondary), host, host alias etc.

Date and time

Set the date and time for your NethServer here.


Here, you can edit IP address details of a network card and assign it to different network zones.

Also, you can create a IP alias for your network card.

Organization contacts

You can update your contact details such s you company name, address, phone no etc.

Server name

Here set your NethServer’s hostname and domain details.

Hope you got a basic idea about NethServer’s Server-manager. Now, let us see how to install a module which is the main topic of this guide.

Installing modules from Server-manager

The beauty of NethServer is its simplicity. Installing, configuring, administrating NethServer and modules from Server-manager is pretty easy and straight forward.

Select any modules you want to install and click ADD button on the bottom to install it. For example, let us install WebTop groupware solution.

To do so, go to Soft center on the left side bar. Check the WebTop groupware checkbox and click ADD to install it.

NethServer will start to download, install and configure WebTop. Just sit back and relax.

After installing it, you can access WebTop groupware web interface with URL: https://<IP_Address>/webtop

The default username and password for WebTop’s interface is admin/admin. You can change the password from the web interface.

You can find username and password for each module in the respective section in the NethServer’s Administrator manual. It would be much better if the developers have included a way to display the Login credentials in a pop-up window or something else after installing each modules. We have to refer the administrator manual for each installed module. I recommend the developers to sort out this for better convenience for the users.

You can find all installed modules under Installed tab in Software center section.

That’s all folks. I will be here with an another article soon. Until, then stay tuned with OSTechNix.
