File Rogue is getting pretty damn good!

JXTA is not a Java package, it is a language independant protocol spec. Most of the work done so far is on the lowest Core layer, which involves services such as peer discovery and grouping. They have written an early IMPLEMENTATION of this in Java.. and why not? Java was built for platform independance and networking.

But anyone can write an implementation in any language they want. It uses XML for communication.

My company has recently become involved in JXTA as we are developing a pure Java P2P file sharing app called File Rogue. (I am lead coder)

Another alternative to Napster, gnutella, and the long dead scour (although isn't there a new breed scour going through beta now by the purchasing company)

*shrug*

ymmv

That's the point... B can tell A what the address of C is and vice versa, but if A and C are both behind a firewall (or many other types of indirect internet connections), neither one can actually "listen" to a port on their true internet connection, so if they try to open a socket to one another, it won't work because they will be talking to the NAT router, IP Masq box, etc, which has no way way of telling which internal LAN address the inbound request is meant for.

Now someone with a direct 'net connection can communicate with someone behind a firewall, as long as they act as a server, and the firewall'd client establishes the connection to them. Once the TCP connection is established, you can stream data both ways no problem.

As the articles more or less states, there are two theorectical ways to connect two firewall'd clients... one method is to have a third computer act as an intermediary server for both clients, handling all messaging and data transfer.

The other way, which he referred to as "blind spoofing" would be to rewrite the initial handshaking signals at the packet level to "spoof" the return address. That way you could "magically splice" two outgoing TCP connections together. AKAIK this has never been done, which is why all programs like Napster, Scour, and ICQ can't establish direct connections between two firewall'd clients.

I'm actually head (well, ONLY right now ;) coder for an all Java P2P file sharing app called File Rogue. We're still in beta testing but it's starting to look pretty good.

File Rogue! *shameless plug*

There is an up and coming alternative, its free its just not Free, Filerogue

sorry bad link, here is a good one
