I really have nothing to back this up but I would *think* that additional services on the same IP might mask the bridge from / confuse some active/reactive probing based bridge disovery attacks. Then again, if active probing is usually only done on a particular (ip, port) pair (the one that someone in China is connecting to, for example), then there's probably no difference anyway.

Running random web services on a bridge-server?
by Martin Kepplinger 16 Nov '13

16 Nov '13

Hi, Sorry for being lazy, I'm not sure if I can figure it enirely out myself: Is there _any_ implication on the status of a bridge in the Tor network when I run random web services like an open website, xmpp server, whatever, on the same device/IP? It'll somehow be more exposed that way but I'd be happy on any opinion. I guess probability that someone finds out that there is a bridge behind my IP is rising. thanks, martin

Exit nodes on a Gandi VPS
by Eric van der Vlist 15 Nov '13

15 Nov '13

Hi list, I am a (happy) Gandi customer and I'd like to support the Tor project by setting up an exit node on one of their VPS (https://www.gandi.net/hosting/iaas). As mentioned on the list of Good/bad ISPs, (https://trac.torproject.org/projects/tor/wiki/doc/GoodBadISPs Gandi does accept Tor exit nodes. I have contacted their technical support who said they did support the Tor project but wouldn't ne able to do specific ARIN declarations and that it would be my responsibility to be reactive to abuse complaints. Despite this perspective (and Julien Robin's bad experience) I am still willing to give it a try. Gandi have data centers in Paris (France), Luxembourg and Baltimore (US) that I can use with the same cost and efforts and I am wondering which of these locations would be more useful for the community. Thanks for your advises! Eric

Hello, is it possible to achieve this behaviour : RELAY RELAY RELAY RELAYRELAY RELAY | | | | | | +--------+--------+--------+--------+--------+ | | ( internet connection 1 ) | | MY RELAY ( on computer #1 ) | | ( LAN connection ) | | PROXY ( on computer #2 ) | | ( internet connection 2 ) | | +---------------+---------------+----------------+ ||| | EXIT_CONNECTION EXIT_CONNECTION EXIT_CONNECTION EXIT_CONNECTION I cant find / undertand the options in torrc documentation. In fact I would have a "ExitConnectionProxy IP:Port" option. Any idea ?

Bad idea to switch from a relay to a bridge?
by Nick 14 Nov '13

14 Nov '13

Hi, I've been running a very low bandwidth relay for a little while with my home ADSL connection, but given the up speed is so poor, and (more importantly) my ADSL provider has stopped switching my IP about every 24 hours, I'd like to switch to be a bridge. However, I'm wondering whether the fact that my IP is already known as a relay means that it wouldn't be useful? That is, if the people bridges try to foil are likely to just blacklist any relays they see by default (it wasn't an exit or guard). Thanks for any advice, Nick

Setting UP an Tor exit node with resrictions

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello! How may I create an Tor exit node with some ports and sites blacklisted? So the user trying to enter an blacklisted page will get an page saying that the maintainer has denied the access to that page/site.

Re: [tor-relays] Checking a bridge
by Gary Anderson 13 Nov '13

13 Nov '13

I have the same worry as Martin. I set up a bridge on AWS 2 weeks ago by following the instructions here https://cloud.torproject.org/ and choosing a bridge image for Ireland. Setup went well, log files on startup tell me my bridge contacts the tor network, and I checked I could use my bridge by explicitly configuring it in a tor client. But the traffic I see in arm is very small (around 100 MB / week) compared to what I observed when I tested a tor relay (over 2 GB in a week-end). On the other hand, I didn't find my fingerprint in Globe. Is there something wrong or can this be a normal situation that happens sometime ? Do all fingerprints end up in Globe ? T.

Traffic in port 9050 in a relay (denial of service attack?)
by jj tor 12 Nov '13

12 Nov '13

Hello all, I've set up a tor exit relay (0.2.4.17-rc, debian testing) on a VPS, and it's running well (about 20Gbs/day). But a lot of traffic (about 50%!) is using port 9050 for incoming connections. It's something more than random scans. Because I am worried, I've run tcpdump on this port and the packets length is about 50-60 bytes long. It seems like DOS or flood traffic: external ip tries to connect and my server refuses (RST, ACK), each time. My OR port is 9001, and, of course, SocksPort = 0 in my torrc. Do you think something is wrong with my relay? Why that traffic if my only tor port is 9001? Should I block that traffic using iptables?
