migrate a tor
by Bruce Ganton 23 Jun '11

Hi all, I am new to this list and should probably lurk for a while to pick up the culture. However, I really want to know.... if it is possible to move/migrate a tor from one computer to another and retain the same identity. I assume this is necessary for the proverbial t-shirt but it would also obviate resetting my weather watch. Bruce

tor-relay+polipo+firefox much slower than TBB - why?
by swsnyder＠snydernet.net 23 Jun '11

I've got an established Tor 0.2.1.30 relay running on a (Linux/x86) machine on my network, and want anonymity while browsing on another machine. Sure, I could just download and run the Tor Browser Bundle (Linux/x86_64), but why? I'm already running Tor, so why not use it for my browsing? So I run Polipo 1.0.4 on the machine running Tor and just point my browser (Firefox) at Polipo by specifying Polipo as a HTTPS proxy. It works but it's slow. After a few weeks I download the current TBB and give it a try, and find that HTTPS browsing is noticeably more responsive than on my tor-relay+polipo+firefox config. I note the same performance difference over the course of a couple of weeks, so I know it is not just a fluke. Can someone tell me why that is? In my configuration both Tor and Polipo are running on a slowish 32-bit machine while the browser is running on a fast 64-bit system. With the TBB, all the software is running on the faster system. Still, though, I have to believe that it is the Tor network that would be the bottleneck in both configurations, not the CPUs. The TBB and my stand-alone Firefox are both of the same vintage, so it's not a matter of one browser just being faster than the other. Maybe my Tor relay is already pegged at the specified bandwidth limit? Hardly. Traffic through the relay averages about %25 of the bandwidth ceiling I set. (That's a topic for another message.) I would much rather be just another client on my Tor relay than to have a special browser. What do I have to do to get the TBB performance with a stand-alone tor-relay+polipo config? Thanks.

Exit policy question
by George Gemelos 05 Jun '11

05 Jun '11

I recently had a dedicated server free up and decided to set it up as a Tor relay. It has 100Mbps unmetered traffic, so I thought it would be a good contribution. Right now I have it set up as a middle node, but I am considering possibly converting it to an exit node. Both my server and I are based in the US. I asked my hosting company about the possibility of running a Tor exit node and they said that they do not have a policy against it, but that if they get a lot of complaints they might set up and ACL on specific ports. So I really would like to reduce the probability of getting any complaints. I have heard about the reduced exit policy. What are people's experience running with that policy? Is there a further reduced set that might be better, in the sense of avoiding complaints, and still remain useful as an exit node? Should I just leave it as a middle node? Thanks in advance for any feedback. Regards, George
