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.

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.

Tor Deprecation Notice
by Damian Johnson 20 Jan '12

20 Jan '12

Hi all. As per ticket 4788 [1] we'll soon be removing relays that are out of date and no longer safe to run, which includes anything older than version 0.2.1.30. When I last checked this included 257 relays [2] and I've already notified the 107 of those that had contact information available. If you're running one of those relays then you'll need to upgrade to keep operating. Sorry about the inconvenience and thanks for running a relay! -Damian [1] https://trac.torproject.org/projects/tor/ticket/4788 [2] https://trac.torproject.org/projects/tor/attachment/ticket/4788/old_relays.…

[warn] Request too large from address '[scrubbed]' to DirPort. Closing.
by Klaus Layer 19 Jan '12

19 Jan '12

Hi, last night the log of one of my nodes showed within 2 minutes about 160 of these messages. Traffic stats show that the incoming bandwidth increased from the average of 300 Mbit/s to more than 400 Mbit/s, where at the same time outgoing traffic dropped. From the peak I see, the requests must have been really big. Does anyone noticed this on other tor servers too? Regards, Klaus

Re: [tor-relays] logging failure in 0.2.3.10-alpha

Thank you very much! Several years ago, I did install a version of tor via the ports tree, but soon switched to building it myself due to delays in new versions being incorporated into the ports and a concern over potentially losing key files, torrc, etc. if I needed to remove it temporarily or during updates. However, I left the infrastructure stuff (e.g., the /usr/local/etc/rc.d/tor script and the /var/db/tor and /var/log/tor directories) in place. The version information line in it still says, # $FreeBSD: ports/security/tor/files/tor.in,v 1.2 2006/08/06 12:26:25 arved Exp $ :-) Anyway, I deleted the --log option from the line that starts/stops tor, and it created both log files this time when I started it. The original script specified /var/log/tor as a log file, so I must have long ago changed it to a directory to hold more than one log file and then forgotten I had done that. /var/log is a directory only writeable by root anyway, and /var/log/tor is a directory only writeable by _tor, so tor would not have been able to create a file called /var/log/tor. Thanks again for the pointer! Scott Bennett, Comm.
