Cute Otter == Tahoe-LAFS + Tor?
by David Stainton 16 May '14

16 May '14

Hi, What is going on with that cute otter hidden service publishing project? What do people think about having it use the Tahoe-LAFS Onion Grid and lafs-rpg instead of telling users to run their own webservers? Tahoe-LAFS could help to greatly increase the security and censorship resistance of the data being published. If the people involved with this were interested in using Tahoe-LAFS as the data store then I would be more than happy to help out with this. (I don't do any web development at all) Sincerely, David

Collecting data to demonstrate TCP ISN-based port knocking
by Christian Grothoff 15 May '14

15 May '14

Hi all, some of you might remember a project called "Knock", which implements a variant of port-knocking in the Linux kernel that can be used to check the authenticity of arbitrary TCP connections and even can do integrity checking of the TCP payload by using a pre-shared key. Knock started as a student project which was presented during the Tor developer meeting at Technische Universität München last July. This was also where Jake added his two cents to help the project to move on. We still … [View More]

Hidden Service Scaling
by Christopher Baines 14 May '14

14 May '14

I have been looking at doing some work on Tor as part of my degree, and more specifically, looking at Hidden Services. One of the issues where I believe I might be able to make some progress, is the Hidden Service Scaling issue as described here [1]. So, before I start trying to implement a prototype, I thought I would set out my ideas here to check they are reasonable (I have also been discussing this a bit on #tor-dev). The goal of this is two fold, to reduce the probability of failure of a … [View More]

Missing days in "Bridge users by transport"
by David Fifield 13 May '14

13 May '14

Do you know what is the cause of the missing data between April 14 and April 22 in this graph? I'd like to be able to account for it when I present the graph. https://metrics.torproject.org/users.html?graph=userstats-bridge-transport&… I don't suppose it is a problem with the bridge, because other transports show the same gap. https://metrics.torproject.org/users.html?graph=userstats-bridge-transport&… https://metrics.torproject.org/users.html?graph=userstats-bridge-transport&… David Fifield

Finding the catch probability
by saurav dahal 13 May '14

13 May '14

In the paper "A New Cell Counter Based Attack Against Tor, Zhen Ling, Junzhou Luo, Wei Yu, Xinwen Fuz, Dong Xuan, Weijia Jia", in Fig. 9, Catch probability graph is drawn. I am interested in finding out this graph using "Shadow Simulator" as a part of my project in graduate studies. Can anybody please tell me how to find out this graph using this simulator. Thanks, -- Saurav
