0.2.3.10-alpha / .11-alpha
by Sebastian Urbach 02 Feb '12

02 Feb '12

Hi, I was wondering if one of you had a message in the log from 0.2.3.10-alpha which was that he coul not access the AES hardware engine and is using software instead. I upgraded to .11-alpha a day later and the message seems to be gone. Does anybody know how to check if he can access the AES hardware engine now or is the feature just disabled in the new version ? Normally he sould be able to access the feature because the Intel CPUs in the system support it, Thanks in advance -- Mit freundlichen Grüßen / Yours sincerely Sebastian Urbach -------------------------------------------------------- Religion is something left over from the infancy of our intelligence, it will fade away as we adopt reason and science as our guidelines. -------------------------------------------------------- Bertrand Arthur William Russell (1872-1970), British philosopher, logician, mathematician, historian, and social critic.

After reading through it, it seems to me that the problem in Roger's point C would be best dealt with in vidalia without regard to IP address or presumed country. When asking whether the user wishes to run a relay, vidalia's dialog could include an instruction something like this: "Before you decide to run a tor relay, please consider whether the government of the country where you live and/or would like to operate a relay might target you for any kind of abuse if that government noticed that you were running a tor relay." As long as the people who have volunteered to provide translations for vidalia's and/or tor's textual interactions with users have sufficient skills to provide such a cautionary note in all of the most necessary languages plus two or three languages spoken widely around the world, then that should take care of the matter. I share the concerns of both Roger and Sebastian regarding undesirable potential results of automating the rejection of entire countries of relays. Scott Bennett, Comm.

Thoughts on InspecTor?
by Steve Snyder 02 Feb '12

02 Feb '12

This application claims to identify bad Tor nodes for the purpose of excluding them from use: http://xqz3u5drneuzhaeo.onion/users/badtornodes/ Anyone have any thoughts on this? The sum of bad-exit-flags (8), exit nodes that alter payload (4), and long-term-misconfigured (27) suggests excluding 39 nodes within the Tor config file. Is this reasonable? Are these exclusions appropriate for relays, or for end users, or neither, or both?

torrc "permission denied" warning
by tony 26 Jan '12

26 Jan '12

In the Tor logs for a relay, I get the following message: Dec 19 19:42:23.662 [notice] Renaming old configuration file to "/etc/tor/torrc.orig.1" Dec 19 19:42:23.662 [warn] Couldn't rename configuration file "/etc/tor/torrc" to "/etc/tor/torrc.orig.1": Permission denied I've played around with file permissions but it doesn't help. Tor seems to be working. Does the error matter? Running Tor on a Ubuntu Server 10.04 LTS Feedback much appreciated.

Do bridges care about DNS?
by Steve Snyder 24 Jan '12

24 Jan '12

Do bridges have a need for name resolution, or it it just a matter of passing a packet from one IP address to another (i.e. from user to Tor node)? Thanks.

Use the HeartbeatPeriod command in your torrc file to provide usage information on a periodic basis with your choice of period. The message logged gives the uptime in days and hours and a rounded figure for bytes sent and bytes received since initialization, so if your node is *only* used as a bridge, these messages will give you rough idea of your bridge's usage. Note, of course, that some of the traffic will be stuff that your node needs for its operation, e.g., a consensus file. Be advised that each period incurs about 1 s of delay in logging the information, so if you want information every hour exactly, for example, you need to specify a period of 3599 s, not 3600 s. Note, too, that the default period is 21,600 s, or 6 hr. Again, "HearbeatPeriod 21599 seconds" should yield a message logged every six hours exactly. Scott Bennett, Comm.

Tor Status graphs
by Geoff Down 22 Jan '12

22 Jan '12

Hi, the read/write graphs in my relay's TorStatus.blutmagie.de page have been broken for some time (flat-lined) but I assumed that was down to my old software. However, I see that all the relays' pages are the same. Is this data no longer available? I had a quick look in the archives for an answer. GD -- http://www.fastmail.fm - IMAP accessible web-mail

How can I tell if my bridge is working?
by Steve Snyder 22 Jan '12

22 Jan '12

New operator of a Tor bridge here. How can I tell that it is being used? With a regular relay I can look up the stats on TorStatus, or I can see that there are n current connections. But a bridge won't be published, and the lower volume of traffic means that there may not be many active connections at any given time. So how do I know if it is working? I mean beyond the absence of any errors logged? Thanks.

Re: [tor-relays] How can I tell if my bridge is working?
by robbie macg 21 Jan '12

Hi, I may have misunderstood the question. I think the simplest way to determine if your bridge is up and running correctly is to check the contents of /var/log/tor/log. Alternatively, try using Vidalia to connect to your own bridge. and log an error. These methods often work well for newer users. You may have something more sophisticated in mind or be trying to accomplish some thing else. If hat's the case, I apologize.
