This could be sent by using HTTP Poster. Alternatively, the URL could be automatically formatted
for the administrator by cOS Core through using the DynDNS option and entering only the
information required for dyndns.org.
The CLI console command httpposter can be used to troubleshoot problems by seeing what cOS
Core is sending and what the servers are returning:
Device:/> httpposter
Note: A high rate of server queries can cause problems
Dynamic DNS services are often sensitive to repeated logon attempts over short periods
of time and may blacklist source IP addresses that are sending excessive requests. It is
therefore not advisable to query these servers too often, otherwise they may cease to
respond.
A repost for an individual server can be forced with the command:
Device:/> httpposter -repost=
Where is the position of the object in the list of posters. For example, to force a report of
the second in the list:
Device:/> httpposter -repost=2
HTTP Poster Has Other Uses
HTTP Poster may be used for other purposes than dynamic DNS. Any requirement for cOS Core to
send an HTTP GET or POST message to a particular URL could be met using this feature.
