Direct connection
 

Will gnutella clients respond to queries that dont come from ultrapeers?

Here is the theoretical situation;

I have a gnutella client A running a prototype gnutella client, and another remote gnutella client B, running something like limewire, etc.

B is connected to the gnutella network.
A is not connected to the gnutella network.

If i know the IP of B, I can send a query to B from A, but will B accept the query, and will B respond directly to A, or will it attempt to respond via the gnutella network?

Im asking this for security purposes, and because i think it might be a hnady tool

It's a direct connection so yes, it will work.

so, the querying client wouldnt have to handshake with the other client? And there would be no ping/pong messaging between them? you could send the query, and the client would reply directly to you, rather then trying to reply to you through the gnutella network?
