# NextDHCP
[](https://goreportcard.com/report/github.com/nextdhcp/nextdhcp)
[](https://github.com/nextdhcp/nextdhcp/releases)
A DHCP server that chains middlewares. Similar to Caddy and CoreDNS
NextDHCP is an easy to use and extensible DHCP server that chains plugins. It's based on the [Caddy server framework](https://github.com/caddyserver/caddy/) and is thus similar to [Caddy](https://caddyserver.com/) and [CoreDNS](https://coredns.io/).
## Getting Started
The following instructions will get you a local copy of the project for development and testing purposes. For production deployments please refer to the documentation hosted on the project website [nextdhcp.io](https://nextdhcp.io). Note that this project is still in early alpha and may not yet be considered stable.
### Prerequisites
In order to install, hack and test NextDHCP you need a working [Go](https://golang.org) environment. Since this project already adapted go modules you should use at least version 1.12. For testing it is also recommended to have
at least one virtual machine available.
### Installing
If you just want to install NextDHCP without planning to hack around in it's source code the following command should be enough to install it
```
go get github.com/nextdhcp/nextdhcp
```
This will install the NextDHCP binary into `$GOPATH/bin`. If you want to start hacking on the project follow the steps below:
First clone the repository to a folder of your choice
```
git clone https://github.com/nextdhcp/nextdhcp
```
Finally, enter the directory and build NextDHCP
```
cd nextdhcp
go generate ./...
go build -o nextdhcp ./
```
### Usage
Before starting NextDHCP you need to create a configuration file. A typical configuration file for a local subnet can look like this:
```bash
192.168.0.100 - 192.168.0.200
lease 1h
option {
router 192.168.0.1
nameserver 192.168.0.1
}
```
Or, if you need to serve multiple subnets or multiple network interfaces you can also use dedicated blocks:
```
10.0.0.10 - 10.0.0.20 {
lease 1d
}
192.168.0.1/24 {
lease 1h
range 192.168.0.100 192.168.0.200
option router 192.168.0.1
next-server 10.1.1.1
}
```
Place your configuration into a file called `Dhcpfile` and start NextDHCP as root:
```
sudo ./nextdhcp
```
For a list of supported plugins please checkout the content of the [*plugin*](./plugin) directory.
## Plugins
- [**log**](./plugin/log) - configure log output and level
- [**database**](./plugin/database) - the lease database to use. Defaults to the builtin [bbolt](https://github.com/etcd-io/bbolt)
- [**ifname**](./plugin/ifname) - sets the network interface a given subnet should be served on
- [**lease**](./plugin/lease) - configures the lease time
- [**nextserver**](./plugin/nextserver) - advertise a TFTP boot server
- [**option**](./plugin/option) - configure any DHCP options
- [**ranges**](./plugin/ranges) - lease IP addresses from pre-defined IP ranges
- [**servername**](./plugin/servername) - sets the server hostname on DHCP messages
- [**static**](./plugin/static) - lease static IP addresses to clients based on their MAC address
- [**gotify**](./plugin/gotify) - send push notifications for IP address leases and DHCP requests via gotify
- [**mqtt**](./plugin/mqtt) - extract and publish DHCP request/response information to MQTT
