Hello thanks for the reply!
I'v been found on that IRC Channel on EFNet this host:
198.247.163.147:6346
i.e. After I'm connected to the host, I send this data but the host don't reply me!

"GNUTELLA CONNECT/0.4\n\n"

I'm waiting for "GNUTELLA OK\n\n" but I don't receive any string!

May be the host bad? I don't know...
