I've personally used Linux's NetEM for testing my Tor Circuit Build Timeout learning code: http://www.linuxfoundation.org/collaborate/workgroups/networking/netem It worked well but it has a major drawback in that if you use netem on the same machine as your code is running, you can't do real packet loss simulations because the Linux networking stack hints to the TCP layer that the loss was artificial so that window sizes are not adjusted as they would be in reality: https://www.linuxfoundation.org/collaborate/workgroups/networking/netem#Caveats Getting a patch to disable this behavior would be a great help. Otherwise, I think we need to revise this task on our website to say that we're looking for a Tor network simulator, not a slow network simulator.

Simulator for slow Internet connections
Hi, I was going through the "Coding Projects" site the other day and spotted that Tor is in need of a simulator for slow connections. I have written something similar as a part of my M.Sc., so I thought I could contribute by adapting my code to Tor's needs. First of all, has there been any progress on the subject (so that I don't double someone's work)? If I understand correctly, these technical things need to be done: 1) allow to alter parameters of an internet connection on one's computer and 2) allow to measure how these affect the performance of a Tor client (by performance I mean the time to download/upload data from/to internet) Is there something that is not mentioned in the description and might need to be taken into consideration? Btw, my code is partly in Java - is that acceptable or should I use something else (C++ perhaps)? And finally, will the code I supply be used by anybody? ;) Best Regards, Maciej Zbierski *** To unsubscribe, send an e-mail to majord...@torproject.org with unsubscribe or-talkin the body. http://archives.seul.org/or/talk/

Hi Daniel, I am surprised that nobody on this list that is more knowledgeable than I has responded to your request. I am certainly no expert here, but based both on what has been posted on this list previously and the TLS entries that ended up in your debug log, I would have to wonder if your problem doesn't have to do with an incompatibilty between the version of Tor you are using and the version of SSL you are using rather than being a problem with your school's filtering Tor. I did not respond sooner in part because, based on my (admittedly limited) understanding of these issues, I did not see a conflict between what you posted you were using, based on recent other posts about this. Still there have been recent (say the last 6 months or so) issues between Tor and SSL. I can only hope that either you can research this some yourself or somebody else with more knowledge about this will post. Good luck!

Re: Arm Release 1.4.0
Arm should work just fine under BSD with the exception of the connection listing. The problem there is that FreeBSD's netstat lacks the flag to list the pids associated with connections (so I can't narrow the list to tor connections), ss is a completely different program (a spreadsheet application instead of connection resolver), and lsof either had similar issues, though I don't recall exactly what. If you know a method of getting the connections for a given process under FreeBSD then I'm all ears. :) That said, everything else (bandwidth graph, logging, configuration editing, etc) should work just fine. -Damian On Tue, Nov 30, 2010 at 10:56 PM, John Case wrote: > > Hi Damian, > > On Tue, 30 Nov 2010, Damian Johnson wrote: > >> Hi.
