In this tutorial, we will install and configure a DHCP Server on Ubuntu Linux. Dynamic Host Configuration Protocol (DHCP) is a network service for automatically assigning IP Addresses to clients on a network without having to manually configure it on every device. It follows a server-client arch...
Next, it's a good idea to create a central repository for DHCP backups, preferably on a network share that you also back up regularly. You might make a structure that looks like the following. Figure 10. Use multiple folders on a network share to store backups of all DHCP servers. You...
them with fake DHCP Response before the authorized DHCP Response comes to the clients. The fake DHCP Response often gives its IP address as the client default gateway -> all the traffic sent from the client will go through the attacker computer, the attacker becomes a “man-in-the-middle”...
When a computer requests network information from the DHCP server, the DHCP will update the DNS zones –dyn.example.org : the zone that will map hostnames to IP address –201.30.172.in-addr.arpa : the zone in charge of reverse lookups ...
Port forwarding is useful because you can access your router from outside of your network and be redirected to the computer you need inside of your network. The problem is that these two wonderful things rely on one premise: your internal IP addresses don’t change. If your router changes ...
Declarations: define the network topology, state a clients is in, offer addresses for the clients, or apply a group of parameters to a group of declarations. Now, open and edit the configuration file to configure your DHCP server. ---On CentOS--- # cp /usr/share/doc/dhcp...

Wired connections are typically named “Local Area Connection,” while wireless connections are called “Wireless Connection”. In the Status window, clickSupport, and in that window, clickDetails.

device you plug into your network will get an IP address in the defined range. Your Raspberry Pi will act as a DHCP server (which was the goal of this tutorial) but also as a DNS forwarder. So, any host added in the /etc/hosts file can be used on other devices on your network. ...
