If not, I vote for such a feature.


I strongly disagree with your vote for such a feature. There may be
anonymity issues involved. Your refusal to have involvement with  
hidden

service introduction may ease the adversarys attempts to locale my
hidden service and identify me as the operator.


I cannot follow how this shall be possible, can you elaborate this?  
The exit policies allow me as a tor node operator not to offer  
connections to certain IPs. In the same way I should have the  
possibility not to offer services for certain hidden services as long  
as I can identify them (that is directory and introduction point  
services).


I want to point out, that there are hidden services which are (at  
least) anonymity issues by their own.



At the very least, such a new feature - if introduced - should be
opt-in; by default, a node should have the ability to be an  
introduction

or rendezvous point.


I'm fine with that. But I think it's not fair to force Tor operators,  
that want to offer their resources for anonymous access, to  
automatically support hidden services as well. They are to different  
services and should be decoupled. So at least an option to switch off  
hidden service functionality is needed. But I prefer a flexible option  
like the one above.

 Hi,

 I get enough spam already.

 I doubt anybody here runs mail4liste.de. It certainly isn't the
 official Tor list archives. (And we did prune email addresses from the
 archives.seul.org lists.)

 Perhaps you should contact somebody at mail4liste.de to get them to do
 so? If they refuse, I suppose I can unsubscribe the address.

 The webmaster has changed to forum to require registration to view.
 I'm not sure this addresses the problem really - I suppose it stops  
 search engines. Or should.
 Do you use a regex to prune addresses from the official archive?

I'd like to see or-talk removed there entirely. It makes no sense to 
publish this besides the official archives, into the bargain 
phpBB-based. I think it's no good idea to publish the entire 
mail-adresses there, even if there's a registration required.

 If you really need to access a flash script you could set up CGIProxy

 anonymity.  I would combine it by putting the CGIProxy on another 
 machine (or virtual machine), then set your firewall to block any/all
  requests that are not to that machine or localhost.  This should
 help protect against failed rewrites by CGIProxy, and potentially
 retain the anonymity provided by Tor.  Please correct me if I am
 wrong!

Hm, I wonder if running your browser explicitly through torify would
help? All network system-calls would be replaced by SOCKS-calls then.

Can anyone comment on this? Not sure if that applies to plugins though.

Hello Sean,

I use flash player over TOR, I don't install Torbutton, its a little 
slow, but I do download larger files at peak, if available.


I use Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.8.1.12) 
Gecko/20080201 Firefox/2.0.0.12 browser.


With Firefox, QuickJava, NoScript and FlashBlock addons to control the 
various java's manually and with flashblock you get a to choose what to 
see on flash.


My Firefox network setting are (tools/options/advanced/network/settings),

manual proxy config...
http proxy: localhost at 8118
ssl proxy: localhost at 8118
socks host: localhost at 9050

socksv5

No proxy for: localhost, 127.0.0.1

My privoxy works on port 8118

Tor access port: 9050

At the same time my (soft  hard) firewalls block all direct internet 
access for both my Firefox  browser and any apps runninh in firefox. So 
Firefox and flash has no exit other than via TOR. I can see the flash 
traffic in Vidalia's bandwidth graph.


For direct internet access I use another browser entirely.

Hope that helps.

Flash and Java virtual machines don't have to honor the proxy settings,
and depending upon your OS, they run as a different pid.

When metasploit released their dns tricks with flash/java, I ran ff2
from torify in osx and found that flash/java were still bypassing the
tor proxy.  I didn't try windows nor linux.
