RSS
An RDF Site Summary (RSS) syndication feed is served by the HTTP Server. This feed contains
up-to-date information regarding the configuration changes that occur on the SGX 5150 gateway.
Specifying the RSS Feed to be Persistent results in the data being stored on the filesystem. The
file used is
/cfg_log.txt
. This allows feed data to be available across reboots (or until the
factory defaults are set).
Each RSS Feed entry contains a standard timestamp in its
<pubDate>
field.
The RSS Feed is a scrolling feed in that only the last Max Entries entries are cached and viewable.
Simply register the RSS Feed within your favorite RSS aggregator and you will automatically be
notified of any configuration changes that occur.
