Testing DHCP Server

Contents:

Test setup with Virtual Box

Prerequisites

To set up a test environment for DHCP server you will need:

  • Linux AG Home host machine (Virtual).
  • Virtual Box.
  • Virtual machine (guest OS doesn't matter).

Configure Virtual Box

  1. Install Virtual Box and run the following command to create a Host-Only network:

    $ VBoxManage hostonlyif create
    

    You can check its status by ip a command.

    You can also set up Host-Only network using Virtual Box menu:

    File -> Host Network Manager...
    
  2. Create your virtual machine and set up its network:

    VM Settings -> Network -> Host-only Adapter
    
  3. Start your VM, install an OS. Configure your network interface to use DHCP and the OS should ask for a IP address from our DHCP server.

  4. To see the current IP addresses on client OS you can use ip a command on Linux or ipconfig on Windows.

  5. To force the client OS to request an IP from DHCP server again, you can use dhclient on Linux or ipconfig /release on Windows.

Configure server

  1. Edit server configuration file AdGuardHome.yaml, for example:

    dhcp:
         enabled: true
         interface_name: vboxnet0
         local_domain_name: lan
         dhcpv4:
           gateway_ip: 192.168.56.1
           subnet_mask: 255.255.255.0
           range_start: 192.168.56.2
           range_end: 192.168.56.2
           lease_duration: 86400
           icmp_timeout_msec: 1000
           options: []
         dhcpv6:
           range_start: 2001::1
           lease_duration: 86400
           ra_slaac_only: false
           ra_allow_slaac: false
    
  2. Start the server

    ./AdGuardHome -v
    

    There should be a message in log which shows that DHCP server is ready:

    [info] DHCP: listening on 0.0.0.0:67
    

Quick test with DHCPTest utility

Prerequisites

Quick test

The DHCP server could be tested for DISCOVER-OFFER packets with in interactive mode.
