Nyx Project Ideas
by Damian Johnson 27 Feb '16

27 Feb '16

Hi wonderful relay operators. It's GSoC season again, where students can be funded to make open source projects like Tor even better! Nyx (previously known as arm [1]) has been my main focus this last year and is inching ever closer to release. For those unfamiliar with it, Nyx is an ncurses monitor for Tor relays providing a bandwidth graph, event log, connections, config editor, and more. Rather than add new features my work has focused on making Nyx simpler and faster, but GSoC provides us an opportunity to do even more. So I'm curious - what do you want from an ncurses monitor? The answer may be 'keep it simple'. Feature creep does us no favors. But if there's a good fit I'd love to mentor a project that makes your lives even better! I'm not overly fond of the ideas I've had so far... * Windows support. This poses a few challenges. [2] * When running multiple tor instances on a single system connect to them all, aggregating the information. So anything come to mind? Cheers! -Damian [1] https://www.atagar.com/arm/ [2] https://trac.torproject.org/projects/tor/wiki/doc/arm#Windows

Light Bandwidth Monitor (like Munin)
by Pierre L. 26 Feb '16

26 Feb '16

Hey all, May be RPi users... and others linux users! I'm looking for a light bandwidth graph software producing html files, to monitor and graph up/down eth0 bandwidth used on my RPi Tor relay. Something like "munin" or "cacti", but I remember this one was very heavy on a RPi v1... It was taking tooo much time to collect/treat/graph :s Which one are you using on your RPi's ? Thx all for your answers !

Hello, i have been running a new relay for a short time period now and would like to bring to your attention the issues faced, that finally led me to refrain from keeping this up any longer: * Documentation was ok (on torproject.org) and the installation (using deb on ubuntu) was easy. * It took quite some time to understand the implications (opening ports in the router, hazarding security to my computers, as i was - to this date - relying on the routers firewall working) - This job of mine basically got delayed until later, when i would have learned, what is needed in that respect. * Next, i noticed a frequent (daily) behavior of the Tor server dropping traffic to around zero. Inspecting this, let me to understand, my provider was disconnecting me and reassigning a new IP on a daily basis, which took some time to propagate. Even worse: It did not propagate on its own, i needed to restart the tor service to reinitialise... * Asking in the online channel, i was guided to change my "Nickname" torrc config to match the dyndns entry corresponding to my server. * But this never made it to the directories, thus forcing me to manually restart Tor on a daily basis in order to force the changing IP address into them. * Finally, i was told, this behavior would be disruptive to the network, i therefore brought the service down for good, wasting the bandwith, i was willing to spend, for the near future. :-) * Ok, otherwise, i would have to pay additional fees to rent a server off-site with a permanent IP, but that would be giving more, than what was easily affordable, as my machine is running 24/7 and the connections open anyway. Thus Tor doesnt seem to be able to absorb the kind of bandwith, i was willing to share long time. This is leaving a sad taste on me, who is pretty much interested in privacy, anonymosity, which led me to avoid the mailing lists with a durable email-address. But just using a read-only one wouldnt allow me to post to the list. That is why i created this one temporarily, just to let you know about my experiences... NewTorKidOnTheBlock (this was the name of my Tor relay)

My cronjob is not working, if it's not picking up the latest version of Tor. Can you recommend a change to my cronjob? I just installed this relay about 5 days ago and created the script two nights ago, so I'm not sure what you mean by "Perhaps it's because you changed your address or orport on 2016-02-18". I'll monitor things and see if anything changes, but I'm more concerned that my cronjob is not working. I also did a "service tor reload" to see, if anything changed and I still show 0.2.4.27 as my Tor version via the arm program. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.15 (MingW32) iQIcBAEBAgAGBQJWz1U5AAoJEH1gNwhiMDZumawQAKeFuwwembr+VsMNH065yhzP +KNbFPzMM9PscX1qv5e3UBhFOI5Rk8vEJkBFxwdEjk2G4sIXD3Y/zNL3+nbTn6VF WcyzlimRNgTBlG4E5t+l3e13aZiLs/9eyUV3LsuchjeGxavno+G0/JKaiWgvrNV9 L6mkVCvRlHj2gcA3h0G4FEV/K+oSSOtD/ZfzL5jVtgS3T2iZuYPb6Z7Mc71bFuUD bgjTmYf6VavbBnqnSdfO8QI0MsNap9M5rBjqlU42J4LwBDW4oMNKjR6F1lkVYdFm 5nGZbMN2dFqSNgxvVIAzTZfNeksnTTmWkm0g3IrHlR3n3GfyC01xOHKap9NAoW6Y dO15zsYcWlYiOWkDCsx067Jn3XqEVtBJl0XERy5WZxFFFDr3Y+LHprN3aySH0bGz EfcIxKwdbpRWygDUnm8Ur22dDl2jVajun5XgQtjesodQjuHQa5oi4kB9m7t7/ThI trqJXwtB1GwQ+OWAR3d8RcjXt8O7ygJwRuk2PXlIfvY3owLOu1j11uDBrV+/HuEP sGKC+tqjEM7wS/rfAose9U7JnjVbb4iUQg3h7f7/ZmkZh1yp76ZixC3yDSAXZJfs wJQGItJcm2xPCHa/ZUhDi0qsDwLND33deJ+ihkqR+FaAn2RjvVbkVAtgZdPF5S+4 vriUnYrcvIRk1Ajx6f9a =r6HX -----END PGP SIGNATURE-----

Re: [tor-relays] Reminder: exit nodes probably shouldn't be using Google's DNS servers
by Tristan 25 Feb '16

25 Feb '16

According to the Tor manual, IPV4 DNS queries are cached by default, but the UseIVP4Cache option says this: NOTE: This option, along UseIPv6Cache and UseDNSCache, can harm your anonymity, and probably won’t help performance as much as you might expect. Use with care! Not sure if it's on by default, or if I should turn it on.

Reminder: exit nodes probably shouldn't be using Google's DNS servers
by Nick Mathewson 25 Feb '16

25 Feb '16

Hi, all! While looking into a bug report, I noticed that an exit node was using one of Google's well-known public DNS servers for its own DNS server. No disrespect to the operators of Google's fine public DNS service, but my sense is that using it for a Tor exit node might not be the greatest idea for users' privacy, having one DNS provider that gets to see so many requests. It's probably a better idea to have your own local cacheing DNS server. Would anybody like to share a guide about how to set one of those up safely and migrate correctly? best wishes, -- Nick

CVE-2015-7547 Tor network stats
by nusenu 23 Feb '16

23 Feb '16

Hi, if we assume for simplicity that every relay running Linux that has not rebooted since 2016-02-16 is vulnerable to CVE-2015-7547, than these are the current stats (optimistic, because we assume that everyone that rebooted did also update). Vulnerable relays: +------------+------------------+-----------------+ | cwfraction | guardprobability | exitprobability | +------------+------------------+-----------------+ | 0.586 | 0.639 | 0.518 | +------------+------------------+-----------------+ (1=100%) Apply patches and reboot. Debian https://www.debian.org/security/2016/dsa-3481 RHEL/CentOS https://rhn.redhat.com/errata/RHSA-2016-0176.html Ubuntu http://www.ubuntu.com/usn/usn-2900-1/
