OK thanks riX.
So, once Bitcoin has connected to at least one node then the -connect option will eliminate the 6667 warnings.
Is Bitcoin using any kind of ‘peer exchange’ or DHT because this still does not seem to prevent the constant Tor ‘exit’ warnings and therefore Tor’s requirement to try a new ‘exit’ node for connection. (which is problematic ! For Tor anyway, not Bitcoin Wink ) This is really what I meant by “However, Bitcoin must try to connect with all nodes to check its not missing any blocks ?” I just communicated it incorrectly.
I2P would seem to be a much easier solution to implement to increase a Bitcoins users anonymity. http://forum.i2p2.de/viewtopic.php?t=3946&sid=213e3cd998db98c4511675ecbba17af4
I’m also testing JonDonym http://anonymous-proxy-servers.net/ (only the paid services support socks !) However, they do accept paysafecards which can currently be brought in exchange for Bitcoins. Grin
