micro dns server
udns is an authoritative, caching DNS server for development and small deployments written in Python using the circuits Application Framework and the dnslib DNS library. udns can be run standalone, via Docker or using the Docker Compose tool. udns is designed to be small, lightweight, fast and flexible. udns fully supports forwarding, caching as well as honoring TTL(s). udns will also read your /etc/hosts file at startup and use this to populate an internal hosts cache so that entries in your local /etc/hosts file are fully resolvable with tools such as host, dig and resolver client libraries.
Installation and Usage
$ git clone https://github.com/prologic/udns $ cd udns $ python setup.py develop $ sudo udnsd --debug # Server $ udnsc --help # Client
$ git clone https://github.com/prologic/udns $ cd udns $ docker-compose up -d # Server $ docker-compose run --rm udns udnsc # Client
$ docker run -d -p 53:53/udp prologic/udns
From PyPi (coming soon):
$ pip install udns $ udnsd # Server $ udnsc # Client
Running as a Daemon:
$ sudo udnsd -d --logfile=$(pwd)/udnsd.log --pidfile=$(pwd)/udnsd.pid
Managing Zones and Records
udns is a full authoritative, caching DNS server and ships with a client to help manage zones and records. Here are some quick examples:
Create new Zone:
$ udnsc create abc.com.
Create new Zone from a file:
$ udnsc create abc.com. abc.com
$ udnsc create abc.com. - < abc.com
$ udnsc list
Show Zone Records:
$ udnsc show abc.com.
Export a Zone::
$ udnsc export abc.com.
This exports the Zone to stdout which you can pipe into an output file for storage using your shell. e.g: udnsc export abc.com. > abc.com
Add Zone Records:
$ udnsc add abc.com. www 127.0.0.1
Delete a Zone Record:
$ udnsc delete abc.com. www
Delete a Zone:
$ udnsc delete abc.com.
You __must__ specify zones as fully qualified domain names with a trailing period. e.g: abc.com.
