Stopping the censoring of tor users (via exit bridges / proxies / OpenVPNs)

Skipping that whoever wants to enumerate, test, block, and share lists of the IP of your final hop will find a way to do so... "flashproxies" - are essentially illegal to use as the operator got stupid, and didn't gave permission. - are unstable as were never intentionally provisioned, and the operators get smart when abuse reports and shut them off. - proxy lists are going to be a pain for you to scrape and maintain Options - run your own volunteer network of last hop "proxies" / bridges - buy them from AWS or wherever "meek" style - partner with or plug into already existing networks of those - get tor relays or bridges to do this I previously wrote in archives that exit relays could bind OpenVPN to extra IP's they configure on their exit relay boxes. Tor daemon has nothing to do with those IP so they never appear in tor's easily blacklistable consensus. Users then OpenVPN over tor to those via use of the relay fingerprint to reach vpn terminator IP over relay localhost to save bandwidth, and on out to clearnet. You can OpenVPN to some list of onions if you don't feel like listing the relay fingerprints / extra input IP's on wikis. But it's not going to stop dedicated blacklisters, and onion doubles bandwidth use. However it could also be used by non-exits that for whatever reason didn't want to be a tor-exit but did want to offer exit via some remote third party vpn service. And strictly social sharing on forums etc could happen for distribution. There are already some exits that for various reasons, intentional or other, do not exit from their OR IP. That is a feature that some tor users do now find and use. And relays don't offer OpenVPN yet which would also give users more than just IPv4-TCP exit scheme. Though it is integrated somewhat, I2P has this manual sort of exit offering model with false.i2p and a few other nodes. [Doesn't seem to require daemon dev work, updated subject, continuing thread reply to relays and talk.]

What do the huge providers have to do within tor circuits?
by torserver＠datakanja.de 29 Feb '16

29 Feb '16

Hello, slowly getting acquainted with running a Tor relay, i am wondering: >From my gathering, tor is - at times - connecting to many instances of akamai CDN services, amazonaws, and other similar services simultaneously. When i say many instances, i mean: a saw a peak exposure of 30 outgoing ports from my server all going to the above 2 alone (as gathered by iftop. I didn't set up snort just yet). This is seen on a NON-Exit-relay and is troubling me: I am aware of Akamai being the premier CDN provider, serving around 30% of internet traffic alone. Their server power, manpower and know-how is huge. And their ability to draw information from any sort of internet traffic is unparalleled. >From my outsider's perspective, they are in the process of building the tools to effectively dismantle the means and purpose of the Tor network at large. That is what is giving me chills, when i watch them acting from inside the circuits. Clearly, they would be able to hide their identity while doing so. And since they aren't, i may be getting something wrong. So that is why i am asking you: Does anyone KNOW, what is going on? NewTorKidOnTheBlock

Any known Tor relay seizures (in Germany)?
by Thomas 29 Feb '16

29 Feb '16

Hello everybody, do you know of any relay seizures of non-exit relays? In the legal FAQ [1] this "risk" is only listed below exit relays. Have there been any of such events in Germany (either exit- or any other nodes)? Would I have to worry about seizures if I run a guard or middle relay in Germany? Regards, Thomas [1] https://www.torproject.org/eff/tor-legal-faq.html.en

Tor Process Being Killed on VPS
by Stephen R Guglielmo 29 Feb '16

29 Feb '16

Hello, I have a VPS with 512 MB RAM. I run nothing on it except nginx and a Tor relay. The relay is an entry guard and moves about 20 MB/s. It seems that the kernel is killing the Tor process with "out of memory" errors. Are there any tips for mitigating this? I don't have the money right now to upgrade to the next higher VPS plan which has more RAM, unfortunately. Maybe there's some config settings that I can modify to limit the RAM usage? Or, am I just out of luck? Thanks, Steve
