Overview

This is a NSS module for innernet host resolution. This provides an alternative to innernet editing the /etc/hosts file.

Installation

1. Install the library:

   $ cargo build --release
   $ sudo install -m0755 target/release/libnss_innernet.so /usr/lib/libnss_innernet.so.2

2. Add the innernet module to /etc/nsswitch.conf. For example:

   hosts: mymachines innernet resolve [!UNAVAIL=return] files myhostname dns
   

Usage

$ innernet list -s | grep fire
  | ◉ 172.28.208.2: fire (...)
$ getent hosts fire.example.wg
172.28.208.2    fire.example.wg
$ getent hosts 172.28.208.2
172.28.208.2    fire.example.wg
$ ping fire.example.wg
PING fire.example.wg (172.28.208.2) 56(84) bytes of data.
64 bytes from fire.example.wg (172.28.208.2): icmp_seq=1 ttl=64 time=22.3 ms

How

The library simply reads the JSON files in /var/lib/innernet to determine host addresses.

It may be desirable in future to provide an option to ask the innernet-server directly via the HTTP API. The /v1/user/state endpoint provides the same JSON that can be found locally on the system.
