DYNAMIC DNS allows to find Abilis with its dynamic address, using a fixed name.
Enter into the Abilis control-program or open the configuration file with the Console configurator and type the following commands.
[10:34:45] ABILIS_CPX:_a res:ddnsCOMMAND EXECUTED [10:34:50] ABILIS_CPX:_save confVALIDATION IN PROGRESS ... WARNING: RES:Tcp Changed "SESNUM" from 103 to 104 VALIDATION SUCCESSFULLY EXECUTED SAVE EXECUTED
On a working Abilis, a system restart (warm start) is required to make the DDNS resource running.
Then activate the resource:

On a working Abilis, an initialization of DDNS and ip-24 resources is required (init res:ddns and init res:ip-24). Remeber to save the configurations (save conf)
The following commands are used to display the diagnostics of the DDNS resource:
It informs about the state of the resource, the ip address of the resource, the account used on dyndns.org and the state of the authentication.
