Simple tool for testing if DNS zone has been migrated successfully.
#Requirements:
- Python 3.x (it may run on 2.x after some corrections, I don't intend to test it)
- dnspython python3 module
- argparse python3 module (this is default package but still worth mentioning)
- ipaddress python3 module (as above)
#Parameters: ./zonetest.py zonefile targetNS [--coma] [--sub filename]
- zonefile - DNS zone as downloaded from the "old" server. Assumed Bind RFC compat.
- targetNS - our "new" name server onto which the zone has been migrated. Can be IP or URL.
- --coma - optional switch allowing to parse csv files (default format is TAB separated)
- --sub filename - use additional nameservers to query for selected subdomains. File can be any text file, content should be formatted one subdomain per file: subdomain:nameserver Nameserver can be IP or URL.
#Troubleshooting
- Script complains about missing dnspython
Do pip3 install dnspython.
Do not do pip3 as a root!
- pip3 fails with
ModuleNotFoundError: No module named 'pip._internal.cli.main'or similar
You are likely running system that provides Python without pip. There are some ways this can be corrected but the most recommended is via pyenv (this can be also done via Homebrew, please read the link!)
After installing pyenv just:
pyenv install [version] - i.e. pyenv install 3.9.0
pyenv shell 3.9.0
All is in the docs.
