RE: Does the Push message still exist?

Try runnin your servent from behind a NAT router, without configuring it
with port forwarding. PUSH messages will be sent to you only in this case,
and if you have something interesting to share so that some people will
request you this way. Your servent should then run as a leaf node, and it is
the Ultrapeer yo which you are connected that will forward the PUSH message
coming from other people.

There's not a lot of PUSH messages. But if your servent runs as an
Ultrapeer, you should see more PUSH messages coming from anywhere, mostly
via UDP, and that your servent should formward to the firewalled node
connected to it via TCP.

So it's probable that you don't implement Gnutella via UDP; PUSH messages
are more frequently sent via UDP now, they transit by TCP now only on the
last hop from the ultrapper to the target firewalled leaf node.

If you support Gnutella through UDP, may be your ISP is filtering incoming
unsollicitated UDP messages coming from random sources that you have not
sollicitated directly. I know that mobile ISPs (through GPRS or UMTS) make
such limitations, but this is probably to avoid costly traffic for their
customers (because the traffic on such connection is billed above about 50MB
to 100MB per month, and P2P can easily exhaust this limit). It's probably a
bad idea trying to run a P2P program over a mobile connection.
