Re: [Flexradio] I don't understand this consequence of running FLDIGI
224.0.0.252 is a multicast ip for link-local topology discovery. It's harmless, and you can probably turn it off by disabling the LLTD service in Windows. See http://en.wikipedia.org/wiki/Link_Layer_Topology_Discovery for more information. On Tue, Feb 2, 2010 at 12:30 PM, John Ragle wrote: > Thanks, David.

Re: [Flexradio] I don't understand this consequence of running FLDIGI
If there is built in to the fldigi development and intent to allow for remoted operation EVENTUALLY, and the use of sockets, named pipes EVEN IF THEY ARE ALL LOCAL TO YOUR MACHINE, will still show up as activity. You can run wireshark for windows and determine if data is being sent out your ethernet and/or 802.11 connection and TO WHOM the data is being sent. Everyone who seriously uses the internet in this day and age of CONSTANT ATTACK (which is absolutely real), needs to know how to use wireshark.
