How to Configure DHCP Server in an Ubuntu VM and Test It in EVE-NG | Step-by-Step Tutorial

Learn how to set up a DHCP server on an Ubuntu VM and test it inside your EVE-NG lab in this step-by-step, beginner-friendly tutorial. In this video, you’ll learn how to: ✅ Update Ubuntu packages before installing services ✅ Install the ISC DHCP server on Ubuntu ✅ Configure a static IP for your DHCP server ✅ Set up a DHCP scope with range, gateway, and DNS ✅ Assign the correct network interface for the DHCP service ✅ Restart and verify the DHCP server status ✅ Test DHCP assignment on Cisco routers, switches, or another Ubuntu VM ✅ Perform ping tests and check DHCP logs Perfect for networking enthusiasts, students, and lab practice inside EVE-NG. 💡 All commands used in this video: 1. Update Ubuntu Packages sudo apt update && sudo apt upgrade -y 2. Install ISC DHCP Server sudo apt install isc-dhcp-server -y 3. Configure Static IP (Example for ens3) sudo nano /etc/netplan/00-installer-config.yaml Sample content: network: ethernets: ens3: dhcp4: false addresses: [192.168.10.1/24] version: 2 sudo netplan apply 4. Configure DHCP Server sudo nano /etc/dhcp/dhcpd.conf Sample subnet configuration: subnet 192.168.10.0 netmask 255.255.255.0 { range 192.168.10.50 192.168.10.150; option routers 192.168.10.1; option broadcast-address 192.168.10.255; option domain-name-servers 8.8.8.8, 8.8.4.4; } 5. Set Interface for DHCP Service sudo nano /etc/default/isc-dhcp-server Set: INTERFACESv4="ens3" 6. Restart and Check Status sudo systemctl restart isc-dhcp-server sudo systemctl status isc-dhcp-server 7. Test DHCP on Another Ubuntu VM sudo dhclient -v 8. Optional: Check DHCP Logs sudo tail -f /var/log/syslog 📌 All comments and additional resources are in the Description. Don’t forget to like, comment, and subscribe for more networking labs!
