[mattchow_FTNT]

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 as below:

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

Example of successful log as below:

# 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.
