rust-ddns (dynamic DNS client)

Requirements:

• cargo
• dnsutils

Installation

./install.sh or RUST_DDNS_INTERVAL=30min ./install.sh

(default interval is 5min)

sudo systemctl enable rust-ddns.timer
sudo systemctl start rust-ddns.timer

Debugging

Set log level to debug:

export DDNS_LOG_LEVEL=debug

Configuration

Default config file (not created automatically): $HOME/.ddns.conf

Custom config path with option -c/--config-file e.g.

DDNS_LOG_LEVEL=debug rust-ddns --config-file ./my.conf

Config file is in yaml format, and must include the following properties:

server: my.dns.provider.com
domain: ddns.domain.com
methods:
    - DELETE
    - POST
    - PUT
records:                    # optional, defaults to A
    - A
    - AAAA
username: api-key/username
password: api-secret/password
---                         # multiple configs split by line break
server: my.other.dns.provider
domain: my.other.domain.com
...  

The above example config would make 6 calls to the same server, one for each method for each record type. You can provide between 1 and 3 methods, either PUT, POST, or DELETE.
