No guard flag?
by Tor Tor 18 Aug '15

18 Aug '15

Hi, I'm running a relay node [1], and it's been up for a few days over 68 days. I was thinking it would get the guard flag around then. It has yet to get the flag or have non-zero guard probability. Any idea why that is? Or what I could do to get it to be a guard? 1) https://globe.torproject.org/#/relay/741488D89B860E59D6391ACA27A157E87EB533… Thanks, G

Guidelines for lifetime of a bridge?
by Tim Sammut 17 Aug '15

17 Aug '15

Hi. Is there a guideline for how long a bridge should exist on a particular IP address? For example, does it make sense to keep a bridge on one IP address forever? Or is it better to move a bridge to a new IP address periodically, perhaps every 120 days? I ask because I saw traffic to my bridge ramp-up fairly steadily, and then quickly drop-off to a low number of clients per day. Thanks! hope you are all well t -- Tim Sammut ~ @t1msammut ~ tim(a)teamsammut.com Ford-Mozilla Fellow at Amnesty International

do not run Tor client and OR relay together!
by starlight.2015q3＠binnacle.cx 16 Aug '15

16 Aug '15

Anyone who has configured a Tor SOCKS5 client to run in a 'tor' instance that also operates as an OR relay should isolate the client to a separate client-only process. The client function disturbs relay traffic forwarding in a manner that lends itself to confirmation analysis. See bug 16585, particularly comment 5 and onward: https://trac.torproject.org/projects/tor/ticket/16585#comment:5 Perhaps read comment 10 first.

Multicore, bandwidth, relays, capacity, location

Tor appears maybe operating at 50% of bandwidth capacity... https://metrics.torproject.org/bandwidth-flags.html https://metrics.torproject.org/bandwidth.html https://metrics.torproject.org/bwhist-flags.html If that's true, more bandwidth won't have any end user affect. So for the moment it might be worthwhile to study reducing node based latency by ensuring relay CPU's have similar free capacity available for circuit negotiation, interrupt processing, and other tor functions. And to consider not dropping more bandwidth weight into already saturated jurisdictions, but dropping some into the Southern Arc and Eastern Zones in an effort to avoid Orion's Belt... https://metrics.torproject.org/uncharted-data-flow.html [Yes I broke the thread because "no subject" and gmail are even lamer than I].

IPv6 vs IPv4 exit policies
by spriver 11 Aug '15

11 Aug '15

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Hi, I just activated IPv6 support for my two exit relays today, but I do not unterstand/misconfigured the exit policies. I just want to open certain ports at IPv4 (the common known reduced exit policy) and open all Ports at IPv6 except 25. How do I configure such a thing? Current sample config is: [snip] IPv6Exit 1 ExitPolicy accept6 *:* ExitPolicy reject6 *:25 [full reduced exitpolicies snipped out] ExitPolicy accept *:50002 # Electrum Bitcoin SSL ExitPolicy accept *:64738 # Mumble ExitPolicy reject *:* But at Globe only this is visible: https://globe.torproject.org/#/relay/F5B1FC9038A5A65FF16D6729AAB2AEDD67F D2F2A https://globe.torproject.org/#/relay/D9D7A9C203C99945D0DCBD545A20C0CB936 7C742 Can someone help me out there?

There's no smoking gun so far though. Some of the speeds are a bit slow, but nothing low enough to explain the extremely low measured bandwidth these relays are getting. The current BW auth measurement results are around 1.0MBit/s for greendream848. I had a couple of measurements in the 300-500KBit/s range. So, if the auths heavily weight towards low individual measurements, things might make sense. Maybe one of the BW auth guys can comment on how the total measurement result is cooked up!?

> Thanks for running the tests. Which exit nodes led to poor performance? I would like to try to reproduce any performance problems. I did not record the nodes (they were in Europe). A simple test you could run on your server is fetching directory info from nodes that have directory functionality enabled. wget http://<relay IP>:<dir port>/tor/server/all e.g.: wget http://176.126.252.11:443/tor/server/all You can get a bandwidth-sorted list of nodes at: https://torstatus.blutmagie.de/ There is a column that has the directory port. > How would you measure performance between my node and a given exit without being influenced by the properties of the middle relay? You can only set me as an entrynode, and you can't pick a specific middle, You are wrong. :-) You can build arbitrary circuits by hand. There are libraries like Stem, Txtorcon, TorCtl and there is a text based, SMTP-like protocol that you can use directly: https://gitweb.torproject.org/torspec.git/tree/control-spec.txt > so how would you know that the low performance was my node and not the random middle relay? Your node would be a non-random middle relay. > > The bandwidth auths probably downrate the measurement results of your server severely because of those slow connections. > > Probably? How can we investigate further? AFAIK, the raw bandwidth auth measurements are not published, only the total result.

I.P. being Blocked?
by Kurt Besig 09 Aug '15

09 Aug '15

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Without going into any detail at this point I'm wondering if others, running a simple middle relay, have encountered any governmental harassment as a direct result of running a relay. The blocking of state agencies e.g, CA.SDI.gov, CA.DMV.gov? Over the past month I've noticed regardless of which browser, machine on my LAN, and wired or wireless connection utilized it's become impossible to connect to any ca.gov site. I've researched my router, cable modem, and firewall settings, all appear to be fine. Spoke with my ISP, for whatever worth that might have, and was assured no blocking or filters were in place that would keep me from reaching these services and my settings looked fine from what they could see from their end. I'm able to connect to ca.gov sites using my phones 4G network or through Tor, however for some reason my home network and associated I.P. is poison. Any experiences/input would be appreciated.
