I couldn't find a 200 OK message

Hello, I am writing a very small Gnutella client in C++. However, I am unable to find anyone who responds with a 200. I keep of 503 busy or Service unavailable. I first get my hosts from a gcache website and then try to connec to those. From their reply, I then try to connect to the UP that they suggest. My code seems to work fine. However, I don't seem to find any one willing to connect. My initial handshake looks like the following and I use it in all cases. Does any one have a suggetion? Thanks

//send the GNUTELLA message plus one empty string at the end
send(sock, buffered, strlen(buffered), 0);
send(sock, "\n", 1, 0);
send(sock, "X-Ultrapeer:True",1, 0);
send(sock, "\n", 1, 0);
send(sock, "User-Agent:GnuSimul/1.0", 1, 0);
send(sock, "\n", 1, 0);
send(sock, "Pong-Caching:0.1", 1, 0);
send(sock, "\n", 1, 0);
send(sock, '\0', 1, 0);
send(sock, "\n", 1, 0);
