Tor Relay Downloading much more data than uploading
by borgersnick＠gmail.com 17 Feb '14

17 Feb '14

The log entry is: Heartbeat: Tor's uptime is 23 days 0:00 hours, with 0 circuits open. I've sent 6.83 MB and received 177.12 MB. I don’t think I made any changes to the torrc, intend to provide a relay. I am using trickle to limit bandwidth consumption instead of the built-in method because I didn’t want to learn about the bursting concept. ExecStart = /usr/bin/trickle -d 500 -u 500 -t .5 /usr/bin/tor --runasdaemon 0 --defaults-torrc /usr/share/tor/defaults-torrc -f /etc/tor/torrc --quiet Running on Fedora. Firewall allows external port 80 and 443 access to the server.

Dynamic upload limit
by Bram L 17 Feb '14

17 Feb '14

Dear list members, I am running a tor relay, but I have an upload limit (50GB/7 days). This limit usually can't be increased too much, because that might affect other network users. I would like to request my provider (university) for a bandwidth-free connection during the night (or whenever the network is not used very much), and a limited version during the peak times. My idea is that this way I could contribute to the Tor network without disturbing other users of my university network. Before I do so, however, I am curious whether it actually contributes to the Tor network. I noticed it takes time for the bandwidth to increase, and if my daytime upload limit is low (e.g. 80 kb/s) and unlimited (Gb/s) at night, my overall contribution could be very limited due to the time it takes Tor to utilize my available bandwidth. Do you have any insights in this matter? Thanks in advance! PS: currently, I drain the 50GB in about a day unlimited or I run at very slow speeds... Both don't give me the feeling I really contribute.

obfs3 a risk to scramblesuit?
by Delton Barnes 14 Feb '14

14 Feb '14

I am running a bridge with both obfs3 and scramblesuit. obfs3 is vulnerable to active probing. Say someone in China makes the mistake of connecting with obfs3 instead of scramblesuit, and active probing identifies it as a Tor bridge. Wouldn't the bridge IP address then be blacklisted, making it impossible for other people to connect even with scramblesuit? Would it make sense, then, as a bridge operator to elect to only support scramblesuit, even though no one will use it for a while? It seems you are only as good as your weakest transport. Thanks, Delton p.s. Would reply to original thread about scramblesuit, but I only just joined the mailing list, and cannot figure out how to reply to preexisting messages.

This time around I registered server transport 'obfs3' and registered server transport 'scramblesuit'. Thanks!

New obfsproxy transport: scramblesuit [bridge operators: please upgrade!]
by George Kadianakis 12 Feb '14

12 Feb '14

Greetings, a few days ago we integrated ScrambleSuit to obfsproxy. ScrambleSuit is a pluggable transport by Philipp Winter; you can find more about it at: http://www.cs.kau.se/philwint/scramblesuit/ If you are running a bridge, please consider upgrading your obfsproxy to the latest version (0.2.6) by using pip or fetching the latest git master. Unfortunately, we don't have Linux packages yet, but we will hopefully have some soon. In the meanwhile, we would appreciate some testing :) After you upgrade obfsproxy, please change your ServerTransportPlugin line from: ServerTransportPlugin obfs2,obfs3 exec /usr/bin/obfsproxy managed to: ServerTransportPlugin obfs3,scramblesuit exec /usr/bin/obfsproxy managed This will disable obfs2 [0] and enable scramblesuit. It's also important to know that scramblesuit is a password-based pluggable transport, which means that each scramblesuit bridge has a password and if the user doesn't know the password he/she can't connect to the bridge. If you publishing your bridge to BridgeDB, Tor will automatically send the ScrambleSuit password to BridgeDB so that clients can get it. By default ScrambleSuit will generate a random password; if you want to specify your own password, you can use a torrc line like this: ServerTransportOptions scramblesuit password=LLDNOWV7I4P6RKFJMDEMIY2GNU2IQISA By the way, expect not to see any scramblesuit users in the beginning. After a few people have set up scramblesuit bridges, we will roll out a Tor Browser Bundle with scramblesuit enabled. Feel free to ask any questions you have! Thanks! PS: If you are running a bridge without any pluggable transports, please consider installing obfsproxy [1]. Normal bridges are not hard to block these days and we are working on increasing the number of obfuscated bridges out there.
