Adding Obfuscation Types To Windows Bridge
by Keifer Bly 15 Jan '19

15 Jan '19

Hello, So I am running an obfuscated bridge using the tor expert bundle and the compiled version of obfs4. There are some questions I wanted to ask. So, I am looking to add pluggable transports to my bridge, which currently only supports obfs4. I do not have access to any services that offer domain fronting, or third party servers, so I cannot run meek as a result. However, is it possible to add more than one pluggable transport, such as Format-Transferring Encryption or ScrambleSuit and also have obfs4? Are there compiled versions of these pluggable transports for windows? I also wanted to ask, do I need to update obfs4.exe when I update tor.exe? Another question, so I have in my torrc file, Contact Info: followed by an obfuscated version of this email address. However, as seen on my bridge listing at https://metrics.torproject.org/rs.html#details/148BD64BED9F2C27637D986DE032… The contact into does not appear. I do not want to give this email address out publicly, but I do want to register with bridge authorities so they can contact me if something is wrong with my bridge. Here is my torrc, with the ContactInfo line listed. Nickname torland ContactInfo keifer dot bly at gmail dot com SOCKSPort 0 # no local SOCKS proxy ORPort 9002 # public bridge must have an open ORPort ExtORPort auto # configure ExtORPort for obfs4proxy ExitPolicy reject *:* # no exits allowed BridgeRelay 1 # relay won't show up in the public consensus PublishServerDescriptor 1 # publish to the bridge authority # use obfs4proxy to provide obfs4 on port 9003 ServerTransportPlugin obfs4 exec C:\Users\keife\AppData\Roaming\tor\PluggableTransports\obfs4proxy.exe ServerTransportListenAddr obfs4 0.0.0.0:9003 Thanks all very much. --Keifer

Re: [tor-relays] why the network lost 350 relays and some, bridges

I was intrigued by the high number of consumer IP's that these relay are supposed to be running on while seemingly automated updating the relay version. The nickname made me look into Ubuntu Snaps as a possible tor distribution which led me to this snap: https://snapcraft.io/tor-middle-relay. It was last updated the 9th of January and when you download the stable snap it is actually named 'snap269'. So the maintainer in this case is the snap maintainer, but not necessarily the relay(s) operator. I have not looked into how these snaps actually work but it may be the case that they actually needed the PortForwaring functionality to get tor running inside a snap. Given that information it could very well be the case that these relays are not running behind a NAT and not run by the same operator but actually by a group of different people. > Date: Sat, 12 Jan 2019 08:07:00 +0000 > From: nusenu <nusenu-lists(a)riseup.net> > >> this occurred when these relays upgraded from tor 0.3.3.10 to 0.3.4.9 >> (package maintainer update) >> >> All these relays were behind NAT devices and they relied on a tor >> feature that got removed between these two versions: >> >>> o Removed features: >>> - The PortForwarding and PortForwardingHelper features have been >>> removed.

why the network lost >350 relays and some bridges
by nusenu 12 Jan '19

12 Jan '19

As some of you might have noticed the tor network recently lost a noticeable number of relays and bridges as seen in the metrics.tpo relay graphs (0.7% cw fraction). https://metrics.torproject.org/networksize.html https://pbs.twimg.com/media/DwGAESoXgAEoB6L.jpg this occurred when these relays upgraded from tor 0.3.3.10 to 0.3.4.9 (package maintainer update) All these relays were behind NAT devices and they relied on a tor feature that got removed between these two versions: > o Removed features: > - The PortForwarding and PortForwardingHelper features have been > removed. [...]https://trac.torproject.org/projects/tor/ticket/25409 The portforwarding worked only in about 5% of cases so only 350 of the over 6000 relays actually became reachable. Since I still believe these relays are not run by humans I hope they remain unreachable behind their NAT routers. -- https://twitter.com/nusenu_ https://mastodon.social/@nusenu

Tor Relay Configuration: 'MyFamily' missing - byelitehacks

Hi byEliteHacks, thanks for helping the tor network by running relays. please do not forget to set your "MyFamily" configuration parameter on all your relays, so Tor clients are not at risk of using your relays in multiple positions in a single circuit. https://nusenu.github.io/OrNetStats/endtoend-correlation-groups#conatfynndo… Some more background: https://medium.com/@nusenu/some-tor-relays-you-might-want-to-avoid-5901597a… Let us know if you need any help with this. regards, nusenu -- https://twitter.com/nusenu_ https://mastodon.social/@nusenu

tor 0.3.3.x reaches end-of-life on 2019-02-22
by nusenu 06 Jan '19

06 Jan '19

In less than 2 months from now, tor 0.3.3.x will reach its end of life date (2019-02-22). As of today there are still over 640 relays (>10% CW fraction) running that version. If you still run that or another end-of-life version of tor please update to help prevent known issues. -- https://twitter.com/nusenu_ https://mastodon.social/@nusenu

having just 1 exit port - helpful?
by Toralf Förster 06 Jan '19

06 Jan '19

If just 1 port would be opened at an relay, eg. 6697, would this help the Tor network or would only spammers and DDoS use that port? -- Toralf PGP C4EACDDE 0076E94E

Onion v2 HSDir Support (ref: v3 prop224) [was: fishy fingerprint patterns]
by grarpamp 05 Jan '19

05 Jan '19

> relays have a rather distinct signup and fingerprint pattern > usually seen for onion attacks. > ... > a) If you are an .onion operator I'd like to encourage you to switch to onion > services version 3 > ... > so we can start > ... > b) dropping onion version 2 services eventually. These are two separate things not necessarily tied together, thus split for clarity as above. The former a) is up to the onion operator based on their needs. If they have no need for v2, or need v3, they can or should switch to v3, indeed. The latter b) is a feature that some users and operators in and for onionspace explicitly choose and depend on to support common apps, and thus would definitely not like to see yanked out from under them. Better instead to advertise and update the default onion semantics for [new] users to v3, and continue support and backport doable features to v2 until time below... Node operators (tor-relays) would continue offering v2 HSDir support module until such time as the reasons for choosing v2 by those above are supported in v3 or vN. See the threads on this subject on tor-talk, tor-onions, and tickets for more. [CC for inclusion, move there if not relay specific]
