Installing the DHCP Server for the Test Environment

During the previous article, Setting up Networking for the DHCP Server, we have set up the virtual machine for the DHCP Server. In this article, we are going to install the DHCP server application on it.

Things to know before we jump in

Before we jump in setting up everything, I will share the relevant information regarding to the environment, so that you can adjust your commands.

Downloading and installing the Open DHCP Server

In the test environment experiment, we are going to use the OpenDHCPServer, which has the homepage at https://sourceforge.net/projects/dhcpserver. At the time of writing this article, the newest version is 1.66 for which the Windows installer can be downloaded here.

After we downloaded the installer, run it and give the following answers:

1. Leave the installation path of the application set to C:\OpenDHCPServer and press Next.
2. Read the License and press Install to start the installation.
3. After the installation is finished, make sure that Run Program: Install Windows Service is checked and click Finish.

Configure the internal network card of the virtual machine

We need to set the IP address of the internal network card to the IP address that we want to assign on the DHCP server. To do this, go to:

1. Control Panel
2. Network and Internet
3. Network and Sharing Center

To make distinction, click on the name of the connection near the Connection, then click on Details… and you should see the internal MAC address between the properties of the network card.

To set the IP address on the network card do the following:

1. Click on the name of the connection near the connection
2. Click on Properties
3. Select Internet Protocol Version 4 (TCP/IPv4)
4. Click on Properties
5. Fill in into the IP address field: 192.168.128.1
6. Fill in into the Subnet mask field: 255.255.255.0
7. Leave the default gateway empty.
8. Click OK.
9. Click Close.
10. Click Close (yes, second time).

Configuring the system

To configure the DHCP server for the current scenario, use this configuration in C:\OpenDHCPServer\OpenDHCPServer.ini

Later, we are going to automate the edit of this file, so a Jenkins slave can do it.

By default, the port for the DHCP server is closed at the operating system level, to open it, start a PowerShell as an Administrator and run the following command:

And then, restart the DHCP service
