USAGE: noip [check-interval]
CONFIG FILE: /etc/noip/noip.conf
CONFIG FILE SYNTAX:
<hostname> <cred-file> [ip_command]
Tab-separated. Can contain multiple lines.
Config parameter <cred-file> should specify a path to a curl netrc file.
Syntax is:
machine dynupdate.no-ip.com login <login> password <password>
See 'man curl' for details.
Config parameter [ip_command] is optional. It specifies a command
passed to 'bash -c [ip_command] 2>&1' to determine current
public IP. If not provided, default is 'curl -s http://myexternalip.com/raw'.
Useful if you don't want to rely on http://myexternalip.com/raw to determine
your public IP when you have a different way to determine.
Example: "ip -f inet a show br-extenral | grep -Po 'inet \K[\d.]+'"
Default check-interval is 60.
This program reads data from /etc/noip/noip.conf and updates relevant DNS records managed by noip.com.
It also auto-confirms any expiring hosts via noip API.
Current IP address is re-checked using [ip_command] every [check-interval] seconds, upon change the DNS records are updated.
The URL https://dynupdate.no-ip.com/nic/update is used to update DNS records.
Expiry check is performed per .netrc file, once every 172800 seconds.
The URL https://my.noip.com/api/host/<host-id>/touch is used to auto-confirm expiring hosts.
