Update record from Synology

[pamart]

Hello,

I would like to update a DDNS record from my synology...

In Dynamic DNS, there is no option for Hurricane Electric  >:(

I know i can write a script to do that, unfortunately my knowledge with linux is verry limited, so if someone can help me i wll be verry happy  ;D

Thank you.
Fred

you can add a PERSONAL PROVIDER in CONTROL PANEL-EXTERNAL ACCESS_DDNS

Service Provider: Hurricane
Query URL: __HOSTNAME__:__PASSWORD__@dyn.dns.he.net/nic/update?hostname=__HOSTNAME

Then save and Add DDNS:

Provider: *Hurricane
Host name: example.com (record A or AAAA)
User: example.com
Password:your dinamic password in ddns.he.net

test conexion and save

I can update my dinamics ip records A and AAAA

Before i use a script than run in task every 30 minutes

SCRIPT
Save as hurricane.sh and install the packet curl
