2.Setting up DHCP Server
To set up a DHCP server on a Linux server, you can use the "isc-dhcp-server" package. Here are the steps to install and configure it:
Install DHCP Server: First, open a terminal on your server and update the package list:
Then, install the DHCP server package:
Configure DHCP Server: After the installation is complete, you need to configure the DHCP server. The main configuration file for the DHCP server is
/etc/dhcp/dhcpd.conf
. You can edit this file using your preferred text editor, such asnano
orvim
:In this configuration file, you'll specify your DHCP settings. Here's a basic example to get you started:
subnet
: Define the IP address range you want to allocate to clients.range
: Specify the range of IP addresses that DHCP will assign to clients.option routers
: Set the default gateway (router) for clients.option domain-name-servers
: Set the DNS servers for clients.
Customize these settings according to your network requirements.
Specify Network Interface: You also need to specify the network interface that the DHCP server will listen on. Open the
/etc/default/isc-dhcp-server
file:Find the line that says
INTERFACES=""
and add the name of the network interface you want to use. For example, if you want to use "eth0", modify the line to:Start and Enable the DHCP Server: Start the DHCP server service and enable it to start at boot:
Check DHCP Server Status: To ensure that the DHCP server is running without errors, you can check its status:
It should indicate that the service is active and running.
Configure Firewall: If you have a firewall enabled on your server, you need to allow DHCP traffic. For example, if you're using UFW, you can allow DHCP traffic with the following commands:
Replace "eth0" with the name of your network interface.
