# dhcpdoctor Tool for testing IPv4 and IPv6 DHCP services ![Logo](logo.png) ## Description dhcpdoctor sends DHCP requests and checks if it gets an offer from DHCP server. It supports BOOTP+DHCP for IPv4 (`-4`) and DHCPv6 for IPv6 (`-6`). It can operate as a DHCP client by sending requests on the local network via broadcast/multicast or as a DHCP client and relay in one tool by unicasting requests to the specified IP address (`-s`). When relaying requests you can specify the relay address to send from (`-f`). By default the IP address of the interface request is sent from is used. When specifying custom relay from address, keep in mind that the DHCP server will send the response back to the address you specify here, so it must be an address on the machine you are running tests from. You can specify a custom client MAC or DUID (`-c`). By default the MAC address of the interface to send request from is used. You can specify the interface to send requests from with `-i`. Program output and exit codes are Nagios/Icinga [compatible](https://nagios-plugins.org/doc/guidelines.html). Response time from DHCP server is measured and returned as performance data. ## Requirements dhcpdoctor needs needs Python 3.4 or later to run. Since it uses [scapy](https://scapy.net/) under the hood to craft, dissect, send and receive packets, it needs root permissions to run. ## Installing Via pip: ``` pip install dhcpdoctor ``` ## Icinga2 check command You can use dhcpdoctor as a check command from Icinga2 or Nagios. There is [dhcpdoctor.conf](dhcpdoctor.conf) config with a CheckCommand definition for Icinga2 you can use. A service that uses this check command might look like this: ``` apply Service "dhcpd6" { import "generic-service" check_command = "dhcpdoctor" vars.dhcpdoctor_ipv6 = true vars.dhcpdoctor_client_id = "00:11:11:11:11:11" assign where host.dhcpd6 } ``` If you are building an RPM from provided [SPEC](dhcpdoctor.spec) file, the CheckCommand config will be installed to `/etc/icinga2/conf.d/check_commands/dhcpdoctor.conf`. ## Developing We use [poetry](https://poetry.eustace.io/) to manage Python dependencies and virtual environments. To setup development virtual environment: ``` poetry install ``` Run the tool: ``` poetry run dhcpdoctor -h ``` [Vagrant](https://www.vagrantup.com/) can be used to quickly spin-up VMs with DHCP servers to test against: ``` vagrant up vagrant ssh dhcpdoctor cd /vagrant poetry run dhcpdoctor -h exit vagrant destroy ``` See comments in [Vagrantfile](Vagrantfile) for more information. ## Releases ``` poetry run bumpversion patch ``` Instead of patch you can give `minor` or `major`. This creates a commit and tag. Make sure to push it with `git push --tags`. The `dev-version.sh` script will bump the version for development or release as needed (based on whether we are on a git tag or not) and is called in CI jobs. ## Building Here is how to build `dhcpdoctor` using pyinstaller into a single binary file and then package that into a RPM for Red-Hat based systems. The resulting binary is setuid root, because `dhcpdoctor` needs to work on privileged UDP ports, but is usually run as a special user when invoked from Nagios or Icinga. ``` pip3 install --upgrade bumpversion poetry pyinstaller poetry install --no-dev poetry run pip freeze | grep -v egg=dhcpdoctor > requirements.txt pip3 install -r requirements.txt ./dev-version.sh ./build.sh ```
