Tor Weather - Node Down
by torhoste＠tor.host-ed.me 11 Sep '12

11 Sep '12

Hi, this is my very first post to this list. I operate tor exit relays vks24784 and vks24949 and subscribed to Tor Weather Reports. Now, at Sun, September 2, 2012 12:17 am and Thu, September 6, 2012 12:33 am, I received "Node Down" Reports for one of the nodes, 1st report for vks24949, 2nd for vks24784. That said, I noticed that these event resets the respective uptime counters at Atlas web application to "zero" and the node would lose the already earned stable, guard, named, etc. flags for a certain time period. The problem is that both nodes definitely were online to the best of my knowledge (they are 24/7 actually), see http://tor.host-ed.me/nodes/ and official Atlas logs at https://atlas.torproject.org/#details/AAD948023527A6D33FAA96816E4B5F101A664… and https://atlas.torproject.org/#details/B41CBB97CF4DCFF724F272F28FD3F0D683C2F… I even checked the "uptime" through ssh and there hasn't been any reboots occurring. Also, I'm wondering what actually would happen to guard, stable, named, etc. flags if I'd actually need to reboot the nodes cause of maintenance? I feel it unfortunate to lose these flags (also for the Tor network itself) and would like to ask: 1. What does Tor Weather consider a "Node Down" event? 2. How long does it take to regain the mentioned flags? I.e. does the node start from scratch earning them (so to speak), i.e. does it take as long as initially? Last thing I'd like to ask in that context: Do these "Node Down" events and/or needed maintenance reboots have any effect on a potential Tor T-Shirt claim? I'd actually really like to make myself a communicative, green Tor advertising column at some point in time ;-) Thanks!

Hi everyone, my node is actually down and when I want to update my debian, I' got a GPG error: root@foo:/home# apt-get update W: Une erreur s'est produite lors du contrôle de la signature. Le dépôt n'est pas mis à jour et les fichiers d'index précédents seront utilisés. Erreur de GPG : http://deb.torproject.org squeeze Release : Les signatures suivantes ne sont pas valables : KEYEXPIRED 1346668560 KEYEXPIRED 1346668560 KEYEXPIRED 1346668560 KEYEXPIRED 1346668560 W: Impossible de récupérer http://deb.torproject.org/torproject.org/dists/squeeze/Release W: Le téléchargement de quelques fichiers d'index a échoué, ils ont été ignorés, ou les anciens ont été utilisés à la place. Where can I find the procedure to update the GPG key? Thx

Subsidizezed relay proposal
by Dude 10 Sep '12

10 Sep '12

I want to share my thoughts and get feedback on operating a sponsored dedicated exit relay. 0. register a domain name 1. set up a centos linux based dedicated server at a Tor compatible ISP in the USA a. get myself set up as abuse contact for my IPs (I have worked the abuse alias before) b. "10MB" net connection. Most 100MB give you around 9 MB actual and 10 MB give you 6MB actual 2. set up a 'mostly public' exit node and run it intermittently while I tune and debug it 3. operate node for a month before submitting receipts for funding 4. add more nodes if this works I realized I have no assets, so I am going to hold off from creating a LLC type company for financial protection. Are there any more specifics and how/when subsidies will be released? Cheers!

Current state of v0.2.3.x IPv6 bridges?
by Steve Snyder 10 Sep '12

10 Sep '12

I'm wondering about the benefit of running abridge on an IPv6 address. Since the big announcement last December that v0.2.3.9 supports IPv6 addresses for bridges, I've read a few comments to the affect that BridgDB doesn't understand IPv6 addresses. So... what is the state of publishing IPv6 bridge addresses? Will clients requesting a bridge address ever be given an IPv6 address? Can a client specifically request an IPv6 address (or IPv4 address, for that matter)? Thanks.

Operating a sponsored relay II
by Dude 31 Aug '12

31 Aug '12

My research is telling me I can not host a Tor relay at most retail ISPs because it is perceived as an "open relay" and these cause a lot of headaches for ISPs. So that leaves colo, but this gets expensive fast. This is very expensive outside the USA. Could I work as an agent of torservers.net? Is there a FAQ listing friendly ISPs? I understand the need for documentation and receipts for expenses. It might be helpful to get quarterly payments instead of monthly. I was thinking of an USA Llc. for protection. Looking at my notes I now remember an 's-corp' is better for a single owner (simple corporation). Here is a link to the US commercial code for s-corps: http://www.gpo.gov/fdsys/pkg/USCODE-2011-title26/html/USCODE-2011-title26-s… I would be happy to document the process of setting up a US s-corp. if I create one. Cheers!

Has anyone had any success running a relay on an mk802?
by someonelse 29 Aug '12

29 Aug '12

I currently run a relay at home during the day, but would like to run one 24/7. Has anyone had any success doing this with the mk802 or similar device? This site seems to say it's possible: http://romanrm.ru/en/a10/mk802-server "It can run Web/Mail/DNS/DHCP/VPN/Jabber/Mumble/Tor servers..." I think this may work for me since I prefer Debian, something inexpensive (~$70 qualifies), low power and want to run wired Internet. If not the mk802 or mk802-II, then what device would do this better for around the same price? Thanks, Someonelse

Operating a sponsored relay
by Dude 29 Aug '12

29 Aug '12

Hello, I have experience working at ISPs supporting dedicated servers and am interested in operating a sponsored relay. Potential issues I see: # A true 100mb network connection is going to be expensive. Often a 24 port edge switch has just one 100mb uplink port. # As an operator, I might want an LLC to protect me from personal liability in the USA. # Ideally an ISP outside the USA would be used so the server is in a different legal jurisdiction than the operator. This would make payment and communication more difficult. At this time I imagine a server with an encrypted file system and long term log retention disabled. Reasonably hardened OS, but nothing too exotic. I think $100 a month above other costs would be fair. But I do not know how much attention a node would require once it was set up. If it requires a lot of time, more compensation would be in order. I am not looking to make a lot of money doing this, but I can not do it gratis. Cheers, John

Fast relays use lots of memory, which vastly worsens the effects of the "small TLB" problem inherent in all modern CPUs, so running a fast relay on a FreeBSD kernel with superpages support enabled is likely to reduce considerably the CPU load for the traffic served, which is more or less equivalent to increasing the traffic capacity for any given CPU speed. Superpages support has been available since 7.2 for i386 and amd64 platforms, but will likely be available on other platforms at some point. Support on another platform was supposed to appear in 9.0, IIRC, but I don't remember which (ia64?). I'm not sure what will be in later releases, but my understanding is that the kernel development team planned to add superpages support eventually to the rest of the FreeBSD-supported hardware platforms that are capable of it (not, for example, powerpc because that hardware does not support the multiple page sizes involved). Rather than risk triggering OS religious wars here, it might be better to limit OS recommendations to merely which to avoid because they have limitations likely to prevent successful operation of a fast exit node (e.g., non-server versions of Windows). The administrators of fast nodes already know what their current setups are and the current knowledge bases of their staffs are. > >- [remainder deleted -SB] Scott Bennett, Comm.

"Relay info kit" for Tor exits at universities
by Roger Dingledine 24 Aug '12

24 Aug '12

I've spent the week talking to my contacts at US universities, to get them to spin up fast exits. Currently the fast exits in North American universities are: - University of Waterloo (Ian Goldberg) - Boston University (Leo Reyzin) We're now on track to add: - UPenn (Matt Blaze) - UMichigan (Alex Halderman) - CMU (Nicolas Christin) - Georgia Tech (Dave Dagon) and I have professors from George Mason, Illinois, UNM, UMN, UConn, UW, and others looking into it. Wendy and I are talking to some lawyers to try to write up a short (several paragraph) document targeted toward the university's general counsel, for preemptive use by the computer science professors who plan to run the Tor exit. What else should go in a "so you want to run a big exit" info kit? - Pointers to the legal-faq (and dmca template) and abuse-faq. - Pointers to Mike's blog entry: https://blog.torproject.org/blog/tips-running-exit-node-minimal-harassment and my old Tor-at-universities wiki page: https://trac.torproject.org/projects/tor/wiki/doc/TorGuideUniversities - Is there some document suggesting how to SWIP your address, and explaining the importance of having your abuse mails go to someplace other than your general university abuse team? It's touched on in several places but we should make it even clearer. - What are the good answers now to "what hardware should I use, and how should I configure it?" I've been telling people they'll be happiest with Debian, and that something 64-bit and/or with AESNI support will be best. - We should set up a mailing list for university relay operators to share experiences and feel solidarity. I'll also encourage them to sign up here. We might also post a list of university Tor exits somewhere obvious, so new ones can gain more confidence in the idea. What other resources exist already that would be especially useful for new fast exits? What resources don't exist but should? --Roger
