There are times when you need to run your own DHCP server. For me, this was needed to add to my laptop so I can program IP security cameras with my USB Ethernet adapter attached. The software that typically comes with security cameras is total crap with a bad Chinese translation layered on top and is usually for Windows only. It is just easier to connect the cameras to a DHCP network and login than use some clunky badly written Windows-based application. Here is how I installed and configured a DHCP server for my laptop.<\/p>\n\n\n\n

Open a shell prompt and execute the command: sudo apt install isc-dhcp-server<\/strong>.<\/p>\n\n\n\n

\"\"
sudo apt install isc-dhcp-server.<\/figcaption><\/figure>\n\n\n\n

Now, I run ip a <\/strong>to list all the network adapters and names. I found my USB adapter easily.<\/p>\n\n\n\n

\"\"
Use, “ip a”, to list the network adapters and info.<\/figcaption><\/figure>\n\n\n\n

Open the \/etc\/default\/isc-dhcp-server<\/strong> config file and add the interface name of the USB adapter. This defines the network adapter that will be dishing out DHCP IP addresses.<\/p>\n\n\n\n

\"\"

Now we set an IP range for the DHCP server. I usually keep this really small between 10 and 20 IP addresses for convenience. I usually set the starting IP address one octet higher than the IP I set on the USB adapter. Below, you can see I entered, “192.168.10.1” as the IP address of my USB network adapter, then the DHCP range I set at .2 through .10. Set the subnet mask and since this does not need DNS, I just enter a bogus address of the laptop for domain-name-servers.<\/p>\n\n\n\n

\"\"
Set the network adapter info and IP range here.<\/figcaption><\/figure>\n\n\n\n

Restart the DHCP server service.<\/p>\n\n\n\n

\n
\"\"
sudo systemctl start isc-dhcp-server<\/figcaption><\/figure>\n<\/figure>\n\n\n\n

Now I connect the IP POE camera to an injector which then connects to my USB adapter.<\/p>\n\n\n\n

I use Angry IP Scanner to search and find the camera.<\/p>\n\n\n\n

\"\"
Enter the IP range in Angry IP and tell it to scan. <\/figcaption><\/figure>\n\n\n\n

I now navigate to the IP address found and am able to sign in and configure the IP camera.<\/p>\n\n\n\n
