Proposal: only parse .torrc files in torrc.d directory
by iry 03 Feb '18

03 Feb '18

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Dear Tor Developers, I have been testing and using the torrc.d feature for a while, and here is a potential improvement we may make. Currently, when using a torrc.d directory, for example: > %include /etc/torrc.d/ Every file in the directory will be treated and parsed as a valid Tor configuration file. However, sometime, this may not be what users and developers want. For example, users may use /etc/torrc.d/50_user.torrc as the place to put their own torrc configurations. But sometimes, when they use a text editor to edit it, the text editor will leave a /etc/torrc.d/50_user.torrc~ file which will also be treated as a valid torrc file. Another example that also happens very frequently is, when dpkg does an update on /etc/torrc.d/30_distribution.torrc, users' previous configuration can be saved as /etc/torrc.d/30_distribution.torrc.dpkg-old which will also be parsed by Tor. In best case users will just be frustrated because Tor does not work as expected and in worst case this could be dangerous. This could be a severe problem especially because of the following reasons: 1. filename.torrc~ filename.torrc.dpkg-old has higher priority than filename.torrc when Tor does the parsing. 2. In most cases, this will happen without being noticed by the normal suer. Therefore, may I propose to let Tor parse only the files whose name ends with .torrc ? Or maybe even only parse number_filename.torrc for better consistency and for more clear priority order? Thank you very much! Looking forward to hearing your insights!

Re: [tor-dev] No Control Socket when DisableNetwork 1

> My first suggestion would be > [...] > My second suggestion would be to get a Tor binary and run it yourself, > not as part of a package. If it works there, then you know that your > next steps are to figure out why your package isn't working for you Hi Yawning and Roger! Thank you so much for trying to reproduce the bug and teaching me on the generic Tor debugging steps! I agree with you that: > If you can get a minimal case reproducing the bug without a package, > systemd, etc, in the picture, that's a great time to file a trac ticket. It turns out, to successfully reproduce this, we need: 0. set DisableNetwork to 1 1. use User option as part of the Tor configuration 2. run sudo Tor from a different user in a different group Here are the specific steps to reproduce it. I tested it on Debian Stretch but it should be distribution independent: user@host:~$ cat /home/user/my.torrc DataDirectory /tmp/tor ControlSocket /tmp/tor/control.sock ControlSocketsGroupWritable 1 CookieAuthentication 1 CookieAuthFileGroupReadable 1 CookieAuthFile /tmp/tor/control.authcookie SocksPort unix:/tmp/tor/socks.sock user@host:~$ sudo /usr/bin/install -Z \ -m 02755 -o debian-tor \ -g debian-tor -d /tmp/tor user@host:~$ ls -ld /tmp/tor/; ls -l /tmp/tor/ drwxr-s--- 2 debian-tor debian-tor 40 Feb 3 18:19 /tmp/tor/ total 0 user@host:~$ sudo /usr/bin/tor \ -f /home/user/my.torrc \ --User debian-tor \ --DisableNetwork 1 There should be control.sock, but not: user@host:~$ ls -ld /tmp/tor/; sudo ls -l /tmp/tor/ drwx--S--- 2 debian-tor debian-tor 100 Feb 3 20:00 /tmp/tor/ total 8 -rw-r----- 1 debian-tor debian-tor 32 Feb 3 20:00 control.authcookie -rw------- 1 debian-tor debian-tor 0 Feb 3 20:00 lock -rw------- 1 debian-tor debian-tor 215 Feb 3 20:00 state To let Tor really open the control.sock, we need to reload Tor (yes, even though we just start it): user@host:~$ ps -A | grep tor 863 ? 00:00:00 xenstore-watch 927 ? 00:00:04 tor-controlport 11851 pts/0 00:00:00 tor user@host:~$ sudo /bin/kill -HUP 11851 user@host:~$ ls -ld /tmp/tor/; sudo ls -l /tmp/tor/ drwx--S--- 2 debian-tor debian-tor 120 Feb 3 20:01 /tmp/tor/ total 8 -rw-r----- 1 debian-tor debian-tor 32 Feb 3 20:01 control.authcookie srw-rw---- 1 debian-tor debian-tor 0 Feb 3 20:01 control.sock -rw------- 1 debian-tor debian-tor 0 Feb 3 20:01 lock -rw------- 1 debian-tor debian-tor 215 Feb 3 20:01 state I guess the reason Yawning was not able to reproduce it is because User option was not set: user@host:~$ sudo -u debian-tor \ /usr/bin/tor -f /home/user/my.torrc \ --DisableNetwork 1 [notice] Opening Control listener on /tmp/tor/control.sock I was thinking Tor fixing /tmp/tor/ to 2700 may be the reason, but then I cannot explain why this will work with /tmp/tor/ set to 2700: user@host:~$ sudo /usr/bin/tor \ -f /home/user/my.torrc \ --User debian-tor \ --DisableNetwork 0 [notice] Opening Control listener on /tmp/tor/control.sock Would you please share some insights on the this? For temporary workaround using systemd in Debian, I put this line in the [Service] section of /lib/systemd/system/tor(a)default.service : ExecStartPost=/bin/kill -HUP ${MAINPID} Best Regards, iry

small fixes for the sources.list generator (and new options)
by nusenu 03 Feb '18

03 Feb '18

Hi, since the tor relay guide depends on that page and it has a few issues I made some small fixes to it: https://www.torproject.org/docs/debian.html.en Bug 25107: sources.list generator: remove yakkety (we do not offer packages for it) Bug 25107: sources.list generator: add Ubuntu Artful Aardvark (17.10) Bug 25107: sources.list generator: remove zesty (we do not offer packages for it) Bug 25107: sources.list generator: add nightly-master option Bug 24994: point to the actual content describing alpha/stable differences Bug 25107: sources.list generator: update tor alpha version to 0.3.3.x Bug 25107: Update the tor alpha version (noscript page version) Bug 25107: fix sources.list generator for Debian Buster If someone with commit privileges has time to review and merge before the weekend that would be great. https://github.com/nusenu/torproject-webwml/tree/debian_sources.list_genera… Note: I did not care about the "(from source)" option. -- https://mastodon.social/@nusenu twitter: @nusenu_

stem support for v3 ephemeral onion services
by Micah Lee 31 Jan '18

31 Jan '18

Now that Tor Browser 7.5 is released and includes the tor 0.3.2 series, which supports next generation onion services, I would love to make OnionShare use these by default. Here is the issue [1]. OnionShare is written in python3 and relies on stem to communicate with the Tor controller. Although tor now supports v3 ephemeral onion services, stem still doesn't. Just take make sure, here's a quick test, with Tor Browser 7.5 (providing tor 0.3.2.9) open in the background, and using stem 1.6.0: == from stem.control import Controller c = Controller.from_port(port=9151) c.authenticate() tor_version = c.get_version().version_str print("Tor version: {}".format(tor_version)) print("Creating ephemeral onion service") res = c.create_ephemeral_hidden_service({ 80: 8080 }, await_publication=True, key_type='NEW', key_content='BEST') print("{}.onion".format(res.service_id)) == When executed, it still creates a v2 onion address: (env) user@dev ~/tmp $ python3 onionv3.py Tor version: 0.3.2.9 Creating ephemeral onion service wrvsjo4nlww3edsi.onion Right now OnionShare is blocked by stem supporting v3 onions. Does anyone know when we can expect support for this? [1] https://github.com/micahflee/onionshare/issues/461

Starting with contributing to Anonymous Local Count Statistics.
by Aruna Maurya 31 Jan '18

31 Jan '18

Hey! I was going through the Tor Volunteer page and came across the Anonymous local count statistics project. As a student it would be a great starting point and an even bigger opportunity to get a chance to collaborate and learn in the process. I would like to contribute to it, and would love to start as soon as possible. It would be great if someone could guide me through. Thanks for your time!! -- Regards, Aruna Maurya, CSE,B.tech, Blog <https://themindreserves.wordpress.com/> | Medium <https://medium.com/@arunamaurya>

website patches for new Tor relay guide sidenav entry
by nusenu 30 Jan '18

30 Jan '18

Hi Silvia, I submitted a (trivial) patch (in #24881) to add links to the new tor relay guide on the website and to remove previous guides that have been merged into the new guide. I noticed that since than new commits have been merged and these patches will probably no longer apply cleanly. I will try to ensure they apply (rebase) shortly before you have time to look at them if you can tell me approximately when that will be. thanks, nusenu -- https://mastodon.social/@nusenu twitter: @nusenu_
