Ping Plotter does not currently support loose source routing. I played with this feature some time ago and completely failed to get it to work through any of the 3 ISP (and a multitude of destinations) that I tried it on. At that point, I decided it wasn't worth implementing for the time being, and put it back on the suggestion list. I'm not sure exactly which conditions are necessary to get this to work, unfortunately.<br><br>I've also played quite a bit with getting Unix style echo requests implemented. This requires Winsock2 (no biggy with it being included on all OSes now), and a priority on my part to get it in there. I have some working prototypes and I saw some different results from Windows style requests (very cool stuff). I expect to see this in a future version, but I can't say for sure when (it's not been high on the request list so far).<br><br>Thanks for the suggestions!<br><br><br>
