Making Sense of Traceroute

If you’ve poked around the PNRP netsh contexts (and you probably have if you read this blog) I bet you’ve run into the traceroute command.  I’m talking about netsh p2p pnrp peer traceroute.  The help text will tell you that the command “resolves a peer name with path tracing” but it won’t explain the format…

PNRP and pnrp.net

The other day I read a forum post explaining that it was easy to block PNRP traffic at the edge of the network – just block all traffic headed to pnrp.net.  I worry about the user’s motivation for blocking PNRP (peer-to-peer networking and illegal music sharing are not synonymous!) but I feel the need to…

In the next few days, I’d like to post portions of the debugging guide that we’ve been compiling.  First, we need to explain PNRP clouds and cloud states and run through our powerful but cryptic netsh commands.  We’ll start with clouds.
