Advice on configuring Obfsproxy3 transport?
by Steve Snyder 06 Apr '13

06 Apr '13

Attempting to get Obfsproxy3 to work. With Tor v0.2.4.11-alpha and Obfsproxy pulled from https://git.torproject.org/obfsproxy.git yesterday this is what I get at runtime: Apr 05 14:57:23.000 [warn] Server managed proxy encountered a method error. (obfs3 could not setup protocol) Apr 05 14:57:23.000 [warn] Managed proxy at '/usr/bin/obfsproxy' failed the configuration protocol and will be destroyed I have no problems with obfs2, but obfs3 success continues to elude me. These are the relevant lines from my bridge config: ServerTransportListenAddr obfs3 aaa.bb.cc.dd:12647 ServerTransportPlugin obfs3 exec /usr/bin/obfsproxy --managed Any advice on how to get Obfsproxy to work would be greatly appreciated. Thanks.

Obfsproxy doesn't use specified addresses?
by Steve Snyder 05 Apr '13

05 Apr '13

I've got a server with 2 IP addresses, and a bridge running on each address. I followed the instructions for using Obfsproxy, adding this line to each Tor config file: ServerTransportPlugin obfs2 exec /usr/bin/obfsproxy --managed It seems that Obfsproxy is not running on a per-address basis but instead each instance is bound to all addresses. (See below). Is this really how it is supposed to work? Shouldn't each instance of Obfsproxy be bound to a specific IP address? ----------------- # lsof -ni | grep _tor tor TCP aaa.aa.aa.aa:https (LISTEN) tor TCP aaa.aa.aa.aa:57242->000.00.000.000:https (ESTABLISHED) tor TCP aaa.aa.aa.aa:48851->111.111.111.11:torrouting (ESTABLISHED) tor TCP aaa.aa.aa.aa:34865->222.22.222.222:torrouting (ESTABLISHED) tor TCP bbb.bb.bb.bb:https (LISTEN) tor TCP bbb.bb.bb.bb:42826->333.33.333.33:https (ESTABLISHED) tor TCP bbb.bb.bb.bb:https->444.4.444.444:58519 (ESTABLISHED) tor TCP bbb.bb.bb.bb:33745->55.55.555.55:https (ESTABLISHED) tor TCP bbb.bb.bb.bb:44772->666.666.666.666:https (ESTABLISHED) obfsproxy TCP *:34866 (LISTEN) obfsproxy TCP *:41887 (LISTEN)

Never mind - I noticed the bookkeeping during a period when my bridge was carrying very low traffic. On 03.29.2013 eliaz wrote: > My bridge relay often shows regular pulses in its bandwidth graph, as > per the attached. Do these represent some housekeeping on the > network? [attachment scrubbed]
