Project description

A tool for updating route53 addresses, simulating a dynamic DNS service by asking ipify.org and using boto3, it is meant to run via crontab on python3 enabled devices. It uses, dnspython, certifi, requests, and boto3.

Dyn53 is tested against python versions 3.3, 3.4 and 3.5.

Install

pip3 install dyn53

Alternatively, download the package, decompress and run:

python setup.py install

Usage

Configure dyn53 by editing ~/.config/dyn53.conf, if the file is not present, a sample one will be created. Boto3 config is not required, nor used.

> dyn53
2016-07-25 14:22:58,212 - dyn53 - INFO - Creating sample config file: /home/user/.config/dyn53.conf.sample
No config file found, exiting.

> cat ~/.config/dyn53.conf.sample
[dyn53]
hosted_zone_id = My hosted Zone Id
domain = domain.tld.
ttl = 300
debug = False
aws_sec_key = MY SECRET KEY
aws_key = MY KEY

> mv ~/.config/dyn53.conf.sample ~/.config/dyn53.conf
> vi ~/.config/dyn53.conf

> dyn53  -s myhost --debug
2016-07-26 00:42:31,646 - dyn53 - DEBUG - Got ip: 52.37.72.89
2016-07-26 00:42:31,707 - dyn53 - DEBUG - FQDN is already pointing at 52.37.72.89

Notes

  • If no address is passed as argument ([-a address]), ipify.org service will be checked via https to resolve the current public IP address.
  • dyn53 is lazy, if the domain is already pointing to the resolved or given address, it wont update the record.
