Re: Reducing relays = reducing anonymity ? Tortunnel.

Yes, unfortunately quite a few people use it. It hurts the network by endangering exit node operators, and by completely ignoring any of the load balancing that happens in normal Tor. I agree with most of what you have had to say, though, this gets to the heart of why its not just bad for you but abusive to the community. However, I am not sure that I understand how this is the case. Certainly there is a certain amount of sense to the idea that tortunnel traffic may use another system that focuses more on speed if tortunnel was unavailable. However, an assumption is an assumption and I am not sure how much I buy the truth of it. Is there an argument for the problem beyond this? What load balancing mechanisms is it ignoring? Is this ignorance a symptom of what it tries to do, or a symptom of ignorant design (ie just plain ignoring network information that it is the client's job to respect?). I ask for two reasons. The first is logical accuracy, what its trying to do, while bad for user anonymity, doesn't, on its face, seem like a real problem for tor exit node runners. The second is that I have considered writting a client myself (I have some things that I want to play with that is a bit beyond what the current client can do... like rendezvous nodes that don't publish in the public directory) and I wouldn't want to end up being considered an abuser If single-hop users of exit nodes become common it then becomes worthwhile for Tor adversaries to seize or compromise or tap traffic going into exit nodes in order to locate those single-hop users. I have been using the alpha versions that detect anomalous connections from nodes claiming to be tor relays for several weeks and have seen some (but not majority) activity. Although tortunnel-like code can be used for detecting bad exits, i wouldnt be surprised if someone adapted it for p2p botnets spamming etc. *** To unsubscribe, send an e-mail to majord...@torproject.org with unsubscribe or-talkin the body. http://archives.seul.org/or/talk/
Some sites recognize TOR
I have encountered this on several sites, some upon registration or sometimes in google search that the site would recognize that I am using proxy and would ask me to do otherwise. How do they find this out? *** To unsubscribe, send an e-mail to majord...@torproject.org with unsubscribe or-talkin the body. http://archives.seul.org/or/talk/

This is not something to be 'fixed', see: https://trac.torproject.org/projects/tor/wiki/TheOnionRouter/TorFAQ and search for You should hide the list of Tor relays, so people can't block the exits.

Ultimately this makes blocking Tor a lot easier! i made some good experiences by using me - tor - ordinary webproxy - target site on sites which try to block tor users. of course you would want to use a webproxy which does not send X-FORWARDED-FOR etc headers. also, be sure to not do such things for submitting very important data in plaintext (like, without https) because the proxy might log you. but as others noted, doing such things is not exactly what the fine people which made tor hat in mind, and if a website is blocking tor for what reason ever, you should consider not using it at all. most if not all content on the web is accessible via various sites, no need for ones blocking proxies. -- Jerzy Łogiewa -- jerz...@interia.eu On May 21, 2010, at 9:08 AM, Karsten N. wrote: or fetching the exit node list from a tor status site like: https://torstatus.kgprog.com/ip_list_exit.php/Tor_ip_list_EXIT.csv or fetching it from check.torproject.org https://check.torproject.org/cgi-bin/TorBulkExitList.py?ip=xx.xx.xx.xx -- Sprawdź jak zadbać o życie. http://clk.tradedoubler.com/click?p=191431a=1694818g=18733532 *** To unsubscribe, send an e-mail to majord...@torproject.org with unsubscribe or-talkin the body. http://archives.seul.org/or/talk/ *** To unsubscribe, send an e-mail to majord...@torproject.org with unsubscribe or-talkin the body. http://archives.seul.org/or/talk/
