- Once the installation is complete, restart your Raspberry Pi to apply the changes by running the following command:
- sudo reboot
This will restart your Raspberry Pi and activate Mytinydc as the DHCP server. [1]
By following these steps, you will be able to set up your Raspberry Pi as a DHCP server using Mytinydc and enjoy the benefits of automated IP address allocation on your network.
Set a static IP address to your Raspberry Pi
To ensure stable and reliable operation of your Raspberry Pi as a DHCP server, it is highly recommended to assign a static IP address to your Raspberry Pi. By doing so, you can prevent any potential conflicts that may arise with the IP addresses being assigned by the DHCP server.
To set a static IP address, you can follow these simple steps:
- Open the terminal on your Raspberry Pi or connect to it through SSH.
- Edit the dhcpcd configuration file by running the following command:
- sudo nano /etc/dhcpcd.conf
- Within this file, you will see a section specifically designated for “static IP configuration”. Here, you can effortlessly add your desired static IP address, subnet mask, gateway, and DNS server.
- Once you have entered all the necessary information, save the file by pressing “Ctrl + X” and then confirming with “Y”.
- To apply the changes, it is recommended to restart your Raspberry Pi by running the following command:
- sudo reboot
Now, with the static IP address assigned, your Raspberry Pi will always be easily accessible on the network. This is especially crucial for a DHCP server, as it needs to be consistently reachable for devices to seamlessly obtain IP addresses. Enjoy the benefits of a stable and reliable networking solution with your Raspberry Pi! [1]
Install the prerequisites for Mytinydc
To ensure the smooth and efficient operation of Mytinydc on your Raspberry Pi, it is crucial to install the necessary prerequisites. These prerequisites include the following:
