lglass is a Python software package designed for Internet Registries like the DN42. You can generate zone files for DNS and rDNS IPv4/v6, and handle the registry. It is available on GitHub as free software:

$ git clone git://github.com/fritz0705/lglass.git

Running your own Whois daemon

lglass provides an event-based whois daemon with internal caching, which was written in Python. It is very simple to run an instance:

$ ./bin/lglass-whoisd

without the configfile:

$ ./bin/lglass-regtool whoisd -H $HOST -p $PORT

usage: lglass-whoisd [-h] [-4] [-6] [--host HOST] [--port PORT]
                     [--cidr] [--no-cidr] [--inverse] [--no-inverse]

optional arguments:
    -h, --help            show this help message and exit
    -4                    Listen on IPv4
    -6                    Listen on IPv6
    --host HOST, -H HOST  Listen on host
    --port PORT, -p PORT  Listen on port
    --cidr, -c            Perform CIDR matching on queries
    --no-cidr             Do not perform CIDR matching on queries
    --inverse, -i         Perform inverse matching on queries
    --no-inverse          Do not perform inverse matching on queries

Generate zone files

lglass also provides a script to generate zone files from the registry. It's named zonegen.py and requires a registry dump from Monotone.

To generate DNS zones:

$ ./bin/lglass-zonegen -d $PATH_TO_DATA_DIR -n ns1... -n ns2... -e foo.bar.com dns -z dn42

To generate IPv4 rDNS zones:

$ ./bin/lglass-zonegen -d $PATH_TO_DATA_DIR -n ns1... -n ns2... -e foo.bar.com rdns4 -N 172.22.0.0/16

To generate IPv6 rDNS zones:

$ ./bin/lglass-zonegen -d $PATH_TO_DATA_DIR -n ns1... -n ns2... -e foo.bar.com rdns6 -N fd00::/8

Reformat RPSL files

You can also reformat RPSL files using lglass by using the lglass.rpsl module:

$ ./bin/lglass-rpsl < $DATA/inetnum/172.22.0.53_32

lglass.rpsl also supports in-place operation:

$ ./bin/lglass-rpsl -i $DATA/inetnum/172.22.0.53_32

This opens the file, reads the content into memory, seeks to position 0, writes the formatted object and truncates the file. Simple web interface

lglass also comes with a simple web interface written in Python3 using Bottle and Jinja2. It also provides a binary to run it using wsgiref:

$ ./bin/lglass-web

Furthermore you can use any WSGI server like Gunicorn by using lglass.web.application:app as WSGI callback. You can provide a path to the configuration file in the environment variable LGLASS_WEB_CFG.

Configuration

The configuration file format is JSON and allows configuration of the database chain, the listen parameters, the custom messages and the process management.
