Hi Gus. If you're trying to make sense of tor's netstat output then you might find arm to be useful. Its connection panel was made for that... http://www.atagar.com/arm/ http://www.atagar.com/arm/images/screenshot_page2_full.png ___ tor-dev mailing list

It's unfortunately a limitation of the technology we are using. The proxies run as javascript code in peoples' web browsers, and use the WebSocket protocol to relay traffic from the client to the relay. This protocol is designed to allow bidirectional communication from a browser to a web server

Have you considered Hole punching techniques? [1] TCP, UDP, ICMP hole punching... There are many techniques. I don't know if the WebSocket protocol would prevent it. STUN [2] like techniques where a third non-firewalled server helps to traversal the NAT. (Only NAT, not used a proxy.) pwnat [3]

Hey Ian, [There's no such thing as a bi-quadratic residue in this setting; all quadratic residues in this group have one square root which is itself a quadratic residue and one which is not.] I guess you are right. Because (q,2) = 1, all quadratic residues are bi-quadratic residues, hence no
