Hi I stumbled over [1]. As I operate Doedel26 I checked DownloadExtraInfo was default. After change in torrc to 1 and reload 'cached-extrainfo' showed up in /var/db/tor/. Can someone please advice how to deal with it ? Best regards, Felix [1] https://trac.torproject.org/projects/tor/ticket/18489

relay maintenance without losing consensus weight?
by Zwiebel 08 Mar '16

08 Mar '16

Hello, is there a way to shut down Tor relays for a short time without losing consensus weight or bandwidth? Last week I installed a newer Tor version and added more RAM and now my relays lost a third of their bandwidth. Last time I've upgraded the hardware was in January and the relays didn't fully recover from the downtime in the last two months. I'd gladly provide 200Mb/s+ of relay bandwidth if I could, but Tor won't let me. - Zwiebel

Thanks for adding relays! Maybe set a contactinfo? (Whenever a university adds an unusual amount of relays it reminds me of the CMU case though.) http://article.gmane.org/gmane.network.onion-routing.ornetradar/1030 (I'm not implying they are doing anything bad)

misconfig resolution for Tor startup on linux?
by torserver＠datakanja.de 06 Mar '16

06 Mar '16

Last week, i had been erroneously assuming, the daily reassigned external IP addresses from my provider would kill Tor, as someone suggested in the IRC. So i ran a quick "sudo update-rc.d tor disable". Only later, when i learned, the IP change doesnt cause too much trouble, i reenabled Tor. Since then, the tor service doesnt come up on computer startup any longer. I tried all kind of things, like: sudo update-rc.d tor enable sudo update-rc.d tor defaults i even reinstalled Tor completely, but the service does not start automatically any longer. After finding this to be true, i began to start it manually after each reboot like so: sudo service tor start # this does in fact cause the service to run as debian-tor user, as it should! Unfortunately, it is necessary to reboot from time to time, to prevent acceleration in memory fragmentation caused by several programs i use on a daily basis. If not prevented, the latter causes system instabilities and introduces severe risk of data corruption. So back to the basics: i am just a simple Ubuntu user with a machine, that is connected and running basically 24/7 (except for the daily disconnect, as can be seen from the logs). And i would certainly appreciate any suggestion to check for, why upstart doesnt pick up Tor, as it should. From my own understanding, eveything looks pretty normal, like: find /etc -name ?20tor | xargs ls -l lrwxrwxrwx 1 root root 13 Mär 4 04:19 /etc/rc0.d/K20tor -> ../init.d/tor lrwxrwxrwx 1 root root 13 Mär 4 04:19 /etc/rc1.d/K20tor -> ../init.d/tor lrwxrwxrwx 1 root root 13 Mär 4 04:19 /etc/rc2.d/S20tor -> ../init.d/tor lrwxrwxrwx 1 root root 13 Mär 4 04:19 /etc/rc3.d/S20tor -> ../init.d/tor lrwxrwxrwx 1 root root 13 Mär 4 04:19 /etc/rc4.d/S20tor -> ../init.d/tor lrwxrwxrwx 1 root root 13 Mär 4 04:19 /etc/rc5.d/S20tor -> ../init.d/tor lrwxrwxrwx 1 root root 13 Mär 4 04:19 /etc/rc6.d/K20tor -> ../init.d/tor Sorry for asking such an unadorned question here, i simply ran out of ideas. :-( NewTorKidOnTheBlock

Re: [tor-relays] Guard Status vs Middle

>If your relay has been given guard status does this mean that >one's middle status is put on hold or can a relay be in guard >and middle status at the same time? Guard-flagged relays are both middle and guard nodes. Take a look at the relay in https://atlas.torproject.org/ and https://globe.torproject.org/ to see graph-lines of the probabalities

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.]
