Hi all.
I'm trying to write a gnutella client in java and I'm kinda newbie. My problem is that handshake connections are not working. Each time I send GNUTELLA CONNECT/0.6\n\n I receive an answer like
GNUTELLA/0.6 503 Service unavailable
X-Try-Ultrapeers: 207.254.245.54:6346,12.202.167.207:6346,...
I've also tried some versions from gnutella v0.6 spec:

"GNUTELLA CONNECT/0.6\n" +
"User-Agent: LimeWire\n" +
"Query-Routing: 0.1\n\n"

"GNUTELLA CONNECT/0.6\n" +
"User-Agent: BearShare\n" +
"Query-Routing: 0.2\n\n"

but each time i get the same error. Can u please help me. Thanks.
