Yes, that would be helpful to know. >probably isn't responsible for 70% of Tor's traffic. If it's huge, >then perhaps that means people are file-sharing over port 43. Something appears to have gotten altered in transmission here. I don't think I suggested any particular fraction of the tor network's traffic be attributed to port 43, but maybe someone did. What I was suggesting was that the number of exit connections would well be over 70% of the total exit connections for exit policies similar to mine. My exit policy, for example, allows port 80 (http) exits for a finite set of IP addresses, which results in small, but non-zero, exit counts for port 80. Nevertheless, the *burden* upon the tor network is not the same as the traffic volume. The burden of constructing untold millions of illegitimate circuits and tearing them down later is something that I doubt has been calculated. Obviously, though, you would be far more likely to know whether such calculations have been performed than would I. Scott Bennett, Comm.
