Receiving Pong messages without sending a Ping

[jimjim647]

Hey there,

I am writing my own client (in Java) for Gnutella. This is just a coding exercise for me really, but there is one interesting event (that keeps on happening!) and I can't figure out.

From the Gnutella documentation, it says that a Pong message will only ever be sent by a client in response to a Ping. However, I am receiving many Pong messages while maintaining connections to other peers, even when I don't send a single Ping to the network.

Has anybody come across this before?

Kind regards,
Jim
