Re: [tor-relays] confusing error from "tor --verify-config"

Hi, > I would suggest running tor --verify-config as debian-tor user instead of > root After I run the following command I`ve got no output. Is this correct then? I expected a few lines somehow. su -c "/etc/init.d/tor --verify-config" debian-tor > I would suggest not running tor as root .:) > As root you can do: > su debian-tor "tor --verify-config" > I am not running tor as root. Tor runs as "debian-tor". I installed it from the repositories and changed nothing in the permissions. Cheers, Patrice

Updating our IP Address
by diffusae 20 Dec '16

Hi! Yesterday I encountered a strange IP address update via DynDNS: Dec 19 23:00:32.000 [notice] Your IP address seems to have changed to 176.10.104.240 (METHOD=RESOLVED HOSTNAME=my.dyndns.cc).

Dec 19 23:22:38.000 [notice] Self-testing indicates your DirPort is reachable from the outside. Excellent. Publishing server descriptor The DynDNS client updates the IP every five minutes. It looks like somebody has tried to changed / update the IP manually or via spoofed update (DNS) entry. I also recognized the change at the WebGUI of the DynDNS Provider. The changed IP address is an exit node (0111BA9B604669E636FFD5B503F382A4B7AD6E80) in Switzerland. I don't think, that this is a bug in Tor 0.2.9.7-rc. Are there any possible attacks to Tor relays, if they are using a faked IP address? Normally this shouldn't work. Even if the traffic is redirected to an exit node, but I am not sure. Well, it should be safer to use autodetection of the IP though Tor. Regards,

Report of home relay experience (cont'd)
by Rana 20 Dec '16

20 Dec '16

Of the two relays that I run from two different residential premises for some time now, the first, nicknamed ZG0 (has absolutely stable dynamic IP and Stable flag for many days now) is clinically dead despite the measured BW of 100 kbytes/sec. The second, nicknamed GG2 (static IP, Stable, Fast, HSdir) is not dead but is relaying only about 0.5 gbytes per day. That's an average rate of just 4% of its never-changing measured BW of 153 Kbytes/sec (which is equal to 100% of its bandwidth limit in torrc). It currently has 900 connections and made over 16,000 circuit handshakes in the last 6 hours, all of them successful. The two relays run on identical Pies with the same configuration except the bandwidth limit (which is higher on ZG0 than on GG2) and negligible CPU and memory utilization. Comments? Rana

confusing error from "tor --verify-config"
by Patrice 20 Dec '16

20 Dec '16

Hi folks, my relay is running fine [zeiberschnitzel] and it got no errors. I can`t see anything in the logs either. But when I do the command #tor --verify-config I got these outputs: Dec 20 18:20:27.946 [notice] Tor v0.2.8.11 (git-9fc59eddc17a726a) running on Linux with Libevent 2.0.21-stable, OpenSSL 1.0.1t and Zlib 1.2.8.

Learn how to be safe at https://www.torproject.org/download/download#warning Dec 20 18:20:27.947 [notice] Read configuration file "/etc/tor/torrc". Dec 20 18:20:27.956 [warn] /var/lib/tor is not owned by this user (root, 0) but by debian-tor (105). Perhaps you are running Tor as the wrong user?

I would say it`s nothing tragical but I am curios about it. Thanks and Cheers

Flags?
by balbea16 19 Dec '16

19 Dec '16

Hi There, I assume, that this has been discussed here already pretty often. However, it seems to be, that the "stable flag" is only assigned to relays with a static, or at least long lasting, IP address. It also seems to be, that the stable flag is mandatory to get the guard flag. If so, that would mean: Dynamic address = no chance to obtain the guard flag. Is that the truth? Tnx Mike

asymmetry in connections
by Rana 19 Dec '16

On one of my relays I have 389 inbound, 38 outbound connections and 15 circuits What's the connection between these 3 numbers and why such asymmetry in inbound and outbound?

Cloning a relay - duplicate fingerprint
by Patrick DERWAEL 19 Dec '16

19 Dec '16

Hi list, I'm running a relay on a CentOS VM As I have lots of resources available, I wanted to duplicate that VM to bring more bandwidth to the Tor network --> cloned VM, changed IP and mac adresses, OS hostname, Tor nickname and restarted the Tor service Surprise: the fingerprint of the clone is identical to the one of the source VM I have stopped my clone to avoid any issue, but I guess I must have missed something... Any clue would be highly appreciated !!

is it possible to relay using ipv6?
by Flavio Leitner 19 Dec '16

19 Dec '16

Hi, I am trying to configure a relay for the first time but I am behind a cgnat for IPv4. I have a public and open IPv6 though. However, ORPort doesn't accept [ipv6]:443 and it doesn't automatically bind to :::443 either. This is running LEDE tor 0.2.8.9-1. I couldn't find if worth to run over IPv6 or not. Thanks, -- Flavio
