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:
gw-world:/> httpposter -repost=<index>
Where <index> is the position of the object in the list of posters. For example, to force a report of
the second in the list:
gw-world:/> httpposter -repost=2
HTTP Poster Has Other Uses
HTTP Poster may be used for other purposes than dynamic DNS. Any requirement for
NetDefendOS to send an HTTP GET or POST message to a particular URL could be met using this
feature.
