Description

This article describes how to check DDNS server status from command line interface.

Solution

To check ddns status, use the following command:

diagnose test application ddnscd 3

Other available options for this command (not all available in all FortiOS versions):

1. Show Peanut Hull Status.
2. Peanut Hull Reconnect.
3. Show FortiDDNS Status.
4. Reset FortiDDNS Status.
5. Show ddns entries.

Example of a failed log:

ddns_ip=0.0.0.0 ddns_port=443 svr_num=0 domain_num=0

Example of a successful log:

FortiDDNS status:
ddns_ip=208.91.113.230 ddns_port=443 svr_num=1 domain_num=3
svr[0]= 208.91.113.230
domain[0]= fortiddns.com
domain[1]= fortidyndns.com
domain[2]= float-zone.com

Note: The other command options (1,2,4,5) do not produce any output unless ddnscd -1 debug is enabled.
