USAGE

cpanel-dnsupdater.pl [options]

DESCRIPTION

This script is useful for updating the IP address of an A record on a cPanel hosted domain with either a supplied IP, or a detected IP. This allows you to use your own cPanel domain for dynamic DNS instead of having to use a third party DNS service. 

If your specify email address parameters, then script output is emailed to you, otherwise all output is printed to STDOUT.

ARGUMENTS

Required

--host          Host name to update in the domain's zonefile. eg. 'www'
--domain        Name of the domain to update
--cpanel_user   cPanel account login name
--cpanel_pass   cPanel account password
--cpanel_domain cPanel account domain name
--check_host    IP address of host to check for connectivity. eg. 8.8.8.8 or your DNS resolver

Optional

--ip              IP address to update the A record with. This defaults to the detected external IP.
--email_auth_user Email address for SMTP Auth
--email_auth_pass Password for SMTP Auth (use \ to escape characters)
--email_addr      Email address to send successful/error report to (defaults to email_auth_user)
--outbound_server Server to send mail through
--helo            Change the HELO that is sent to the outbound server, this setting defaults to the current hostname
--config_file     Specify the location of a configuration file (defaults to ~/.cpaneldyndns)

Using a Config File (~/.cpaneldyndns)

Instead of passing options on the command line, a configuration file can be used.
Any options specified on the command line will be overriden by the configuration file options.
The file takes the format of 'option=value', eg:
host=home
domain=mydomain.com

The default location of the file is in the home directory of the current user and the default filename is '.cpaneldyndns'

EXIT STATUS

Exits with 1 if there was any issue updating the record, 255 if the end of script was reached in error, and 0 if IP was either changed, or the detected IP matches the given IP.
