Tor grassroots advocacy

2009-03-17 Thread Matthew McCabe
I gave a talk to a small group of people on Saturday at BarCampAustin: 
http://www.barcamp.org/BarCampAustin4  I have also given this talk in 
two of my graduate classes at St. Edward's University.  These kinds of 
informal talks are a great way to educate others about Internet 
censorship, Internet monitoring, what Tor is, how to run a Tor server, 
etc.  In each of my talks, the response has been positive.  If nothing 
else, they now know that their Internet traffic IS being monitored and 
that they have a choice about whether or not to succumb to that monitoring.


If anyone is interested, I will e-mail you a copy of my Introduction to 
Tor presentation.  I may also create a Google presentation and share it 
with the world if there is enough interest...


Has anyone else given these kinds of talks about Tor?  Perhaps we could 
combine our Tor educational resources and put them on a website...?


Thanks,
Matt


Re: more on the Comcast 250 GB/mo. problem

2009-03-13 Thread Matthew McCabe

Scott-

Sorry to hear that you are also having problems with your ISP.  I ended 
up dropping Time Warner and signing up for Earthlink - which actually 
uses the same TWC network.  So now I am back on TWC and must watch my 
p's and q's or I will be kicked off.  I even have the same TWC account 
number...  And, according to the last TWC security official, I will be 
kicked off their network if I get another Tor related complaint.


My solution was to get the cheapest Earthlink connection for my home use 
and to setup a VPS that is running a Tor exit node.  I am using Linode's 
VPS services and have a Linode 540 account that gives me 300 GB per 
month of data transfer.  So I can run a 50K/s Tor exit node without 
worrying about my home Internet being disconnected.  Worst case scenario 
is that Linode tells me to stop running Tor and I do...and then look for 
a more friendly VPS company to do all of my future business with.  But I 
have had no complaints for the past couple months.


Incidentally, Time Warner Cable's security department made it very clear 
that they did not want to have me as a customer.  I explained to them 
that I paid extra for increased bandwidth which I intended to use.  The 
security representative said that I was not a business customer (i.e. 
paying 2-3 times as much for the same connection) and thus they would 
not tolerate any more complaints.  He did not mention any complaints 
about bandwidth...  But it is clear that Time Warner Cable does not care 
about you as a customer unless you are a business customer.  Only then 
will they give you a chance to explain why you have received unjustified 
and unproven complaints. /rant

 Last week I found a voice mail message from a phone number I didn't
recognize, who claimed to be from the Comcast Security Assurance Division,
demanding that I call them at yet another number I didn't recognize.  I called
the normal number to reach Comcast, explained what had happened, and gave that
person the phone numbers.  I was told then that those did not appear to be
Comcast phone numbers and that they had never heard of such a department or
division in Comcast.  I asked whether I should report the incident to the
police.  They said that would be a good idea, so I did report it to the local
police, stating that I suspected a possible phone scam aimed at identity theft.
 The next day (Fri.) I received another call, which I answered before
noticing that the number was the one that had called a day earlier.  The caller
made the same claim as the day before, to which I replied that I didn't believe
them, that I had already reported their number to both Comcast and the local
police department.  I then ended the call and called Comcast again to let them
know what was going on.  That conversation lasted quite a while, during which
time my call got transferred to their tech. support area.  The lady in tech.
support did some investigation and found that the phone numbers in question
were, in fact, Comcast numbers and that the Security Assurance Division was
legitimate after all.  She had never heard of them before, but connected me
into a conference call with someone at the number I had been told to call.
 The upshot was that I was being contacted because their system claimed
that in February my setup had transmitted and/or received more than 250 GB,
an arbitrary limit that exceeding a second time would get my connection shut
off for a minimum of 12 months.  They claimed that my combined transmissions
and receptions had totaled between 661 GB and 662 GB for February, a number
I still do not accept.
 Further, Comcast sales staff and tech. support staff were unaware of any
such limit, much less of specifically 250 GB.  That means that when I was
signed up last August for a reception rate limit of 6 Mb/s (~600 KB/s) and a
transmission rate limit of 768 Kb/s (~76 KB/s), they didn't inform me that
actual usage of those rates would use up a fixed, 250 GB, monthly allotment of
data in less than 4.5 days.  A month or a bit more ago, Comcast finished
upgrading its infrastructure and cable system software, which led to their
increasing the data rates, so that my connection can now run at 12 Mb/s
(~1.2 MB/s) for reception and 1 Mb/s (~100 KB/s) for transmission.  If used
at capacity, these rates can exhaust the monthly data ration in a little over
2 days and 6 hours.  I believe this constitutes deceptive marketing and
possibly even fraud under U.S. law.
 At present I don't have an alternate ISP on tap to replace Comcast, but
I am looking.  Meanwhile I asked how much of the current month's allotment had
already been used (according to their very questionable system) and was told
that they were unable to tell me that.  They said that they deal only with
exception notices issued when someone exceeds 250 GB transferred in a billing
month.  They suggested taking the 662 GB figure, dividing that by 28 days for
February,

Please do not give money to node operators. This will complicate matters

It might also have legal implications. Receiving money for a service

Re: Time Warner bad / VPS recommendations

I take issue with the premise that the only course of action that ISPs 
have is to disconnect customers that generate these complaints.  I know 
that some ISPs simply pass on the complaints to their customers with the 
expectation that the customer fix the problem.  It seems to me that this 
is all the ISP is required to do (see the EFF DMCA response letter for 
details).

Right.  In terms of cost, I'm also considering the cost of our general

In principle {RI,MP,whatever}AA complaints are handled the same as

Re: Time Warner bad / VPS recommendations

I agree that it may be a risk for one organization to own a large number 
of Tor nodes.  But if that organization is a non-profit and run by some 
of the Tor users, developers, and operators on this list, that should 
reduce the risk that the organization will willingly compromise its Tor 
network.


Also, you could setup an independent auditing system in which Tor 
experts could examine the Tor boxes or VPSs to be sure that they are 
not compromised.


It is all about transparency!

Peter Lombardo wrote:


It's a risk regarding a large number of nodes being run by a single

donated a percentage of profits to the Tor foundation.  If they get 
pummeled by CD letters and eventually shut down, at least TOR can 
keep the money for future development.


If I can make a disclaimer, I'm working on such a service where one of 
the 'pay for' plans allow for a user to VPN into a TOR server 
configured to transparently route traffic over the TOR network.  But 
we never use VPS's; only dedicated boxes rented from quasi-random 
ISPs.  I've limited it to one TOR box per ISP so far.

Re: Time Warner bad / VPS recommendations

Yup, I restricted my exit node policy in hopes that it would limit 
torrent traffic and it seemed to work.  However, the last hacking 
complaint was the result of someone making excessive or inappropriate 
postings on a newsgroup or website.  So while the torrent/DMCA 
complaints stopped, the hacking complaints continued.

Yes, and one pertty nice day we have 1 middlemen and no exit node anymore.
  

1 middlemen with hidden services and no exits wouldn't be all that bad, 
actually.



 :-)  Indeed, although there would undoubtedly still be the hundreds of
thousands or millions of other services that would no longer be accessible
via tor.  I am also still pondering the implications/possibilities stemming
from something I had never pieced together from the tor documentation until
someone pointed it out on this list a while back:  hidden services can be
offered from client-only instances of tor; relay mode is not necessary to
run a hidden service.
 However, back to the OP's problem...were potential exit policy changes
suggested in the conversation(s) with Time-Warner?  Others on this list have
satisfied their ISPs by rejecting exits to the ports that were attacked, in
some cases, rejecting those ports only for certain IP addresses.

Tor exit nodes which, in turn, supports everyone's ability to use the

Re: Time Warner bad / VPS recommendations

I sent TWC a modified version of the EFF DMCA response letter for the 
DMCA takedown notices.  I even personally replied to one of the DMCAs 
from an agent for Paramount.  I was only able to personally reply to one 
of the complaints as TWC would not forward me any of the other notices.


The technician from the abuse department said that because my account 
already had 5 complaints, he would disconnect me if I received another.  
He was very clear on that point.  He understood that I was running Tor 
and that this traffic was coming from the Tor network.  Again, there is 
nothing in the AUP or TOS that stated that I could not run a service 
like Tor.  But it does state that violating intellectual property rights 
and hacking are not allowed.  As I explained previously, 3 of the 
notices were DMCA notices (copyright violations) and 2 were hacking 
complaints.  This tech and TWC believe that the user of their service is 
responsible for any of these violations.  Thus, it seems that they may 
try to disconnect my service based upon these 5 complaints.


Again, I would rather setup Tor on a VPS if anyone has a recommendation 
for a company and hosting plan!

Need help with MPAA threats

Hello-

Time Warner shut off my connection again last night due to a complaint 
from the MPAA.  They claim that I downloaded 2 movies and 1 TV show.  
This traffic, in fact, must have come through my Tor exit node.


I explained to the customer service agent that I am running a Tor exit 
node and that the traffic must have come through the Tor network.  He 
said that because this is the 3rd complaint, the MPAA may take me to 
court and sue me for $100,000 per violation.  He also claimed that 
others in similar situations have lost in court...whatever that means.


Here is where I need your help.  First, is there a good way to filter 
out torrents in my exit policy?


Second, have any exit node operators in the US had similar complaints 
from the MPAA?  If so, how did you handle the complaints?


Lastly, has anyone in the US gone to court as a result of using Tor?  If 
so, do you have a reference for a good lawyer?  At this point, I want to 
continue running a Tor exit node but also want to investigate my legal 
options if the MPAA takes me to court.

Abuse complaint

2008-10-07 Thread Matthew McCabe

Hey-

Last night, Time Warner Cable temporarily disabled my account due to an 
alleged attack coming from my IP address and targeting a server in 
Europe (Denmark I believe).  Below is the e-mail I sent them to respond 
to the complaint.


Does anyone have any suggestions on how to respond to these complaints?  
Is IP filtering the best (or only) option for addressing TWC's issues?


Thanks for your help,
Matt


Dear Time Warner Cable,

Last night I was notified that my cable modem Internet service had been 
temporarily disabled due to an abuse complaint.  I called and left a 
message on your abuse telephone number last night and received a call 
today from one of your representatives.  She explained that an attack on 
a server in Europe had been launched from my IP address.  I explained to 
your representative that I am running a Tor relay node which someone may 
have used to launch an attack.


Here is a description of what Tor is (from torproject.org):
Tor is network software that helps users to enhance their privacy, 
security, and safety online. It does not host or make available any 
content. Rather, it is part of a network of nodes on the Internet that 
simply pass packets among themselves before sending them to their 
destinations, just as any Internet host does. The difference is that Tor 
tunnels the connections such that no hop can learn both the source and 
destination of the packets, giving users protection from nefarious 
snooping on network traffic. Tor protects users against hazards such as 
harassment, spam, and identity theft. In fact, initial development of 
Tor, including deployment of a public-use Tor network, was a project of 
the U.S. Naval Research Laboratory, with funding from ONR and DARPA. 
(For more on Tor, see https://www.torproject.org/.)


To be clear, this attack was not launched from any computer that I own 
and instead may have come from the inappropriate use of the Tor 
network.  I explained to your representative that if she would forward 
me the abuse complaint, I would configure Tor so that this server would 
not be accessible from my Tor relay.  Specifically, I will deny access 
to the server that was attacked from my Tor relay using IP address 
filtering.  Thus, I need the IP address of the server in question before 
I will be able to setup this policy.


If you receive any new abuse complaints for my account, please e-mail or 
call me before disabling my Internet connection.  If you give me 
specific information about the abuse complaint, I will do my best to 
immediately address the issue.


Here is my contact information:
