Port Forwarding Question
by William Pate 17 Mar '20

17 Mar '20

This constantly trips me up. In my modem settings, I'm offered these options for port forwarding. I know I need to open 9001, but what do I enter into the external port fields? Thank you! William Pate willpate(a)pm.me 512-947-3311 inadequate.net

Fwd: Upcoming Tor security releases to fix a denial-of-service issue
by Nick Mathewson 16 Mar '20

16 Mar '20

---------- Forwarded message --------- From: Nick Mathewson <nickm(a)torproject.org> Date: Mon, Mar 16, 2020 at 1:25 PM Subject: Upcoming Tor security releases to fix a denial-of-service issue To: <tor-talk(a)lists.torproject.org> Hello! Some time this week, we currently plan to put out a set of security updates for all supported versions of Tor. These releases will fix a pair of denial-of-service bugs: one that we are classifying at "low" severity, and one that we are classifying at "high" severity. Our recommendation will be for everybody, including relays and clients, to upgrade once packages are available for their platforms. Although these vulnerabilities are "only" denial-of-service issues, any denial-of-service attack against Tor could be leveraged by an attacker to aid in a traffic analysis attack. To the best of our knowledge, these vulnerabilities are not being exploited in the wild. Currently supported release series are 0.3.5, 0.4.1, 0.4.2, and 0.4.3 (alpha). If you have not yet upgraded to one of those, the time to do so is soon. For our policy and process for handing security issues, please see: https://trac.torproject.org/projects/tor/wiki/org/teams/NetworkTeam/Securit… best wishes, -- Nick

Consensus Weight Dropping/Authority Issues?
by John Ricketts 16 Mar '20

16 Mar '20

Hello, I have been watching the consensus weight and bandwidth of all of my 50 exit nodes drop consistently over the past few months. I have not made any hardware changes in my data center and actual customers have not complained about any performance issues. Operating systems and Tor version are up to date. I'm dedicating a significant portion of bandwidth to these nodes - 10gbit/sec. Am I having issues with the bandwidth authorities? I'm growing frustrated with my performance to resources ratio, I should be doing far better than this. Please throw ideas at me - open to any ideas. Thanks! John Quintex Alliance Consulting

Relays will be getting clock skew warnings today
by Roger Dingledine 14 Mar '20

14 Mar '20

Hi folks! One of the directory authorities, dizum, has a wrong clock today. And it is causing warning lines for every relay who interacts with it. :( The log lines will look like this: Mar 14 16:17:40.121 [warn] Received directory with skewed time (DIRSERV:45.66.33.45:80): It seems that our clock is behind by 2 hours, 0 minutes, or that theirs is ahead. Tor requires an accurate clock to work: please check your time, timezone, and date settings. I contacted the directory authority operator and he is working on fixing it. Hopefully he'll get it fixed today, and we can point the flood of concerned mails to this thread. :) Thanks, --Roger

Any tor relay watchdog services?
by Layer13 13 Mar '20

13 Mar '20

Hello, I'm writing to query about tor relay watchdogs and ask if there are any services to check if tor reachable from the internet and if not it would send me an automated email telling me that my relay is down. A little bit of backstory on why I need this: so a couple of days ago (13 to be exact) my server had an issue and rebooted, since that reboot I didn't start my relay node and it was down for 13 days until I noticed it today.

website support
by potlatch 13 Mar '20

13 Mar '20

Hello Tor, I have a few exit relays on the Tor network but generally I'm flying blind. Why isn't there an index of tor relays that can be accessed? Why isn't the tor access via it's website able to deliver me to the software pages? Why is the graphic display of tor connections over 5-years old? I thought tor was expert in data delivery and security. potlatch(a)protonmail.com Sent with [ProtonMail](https://protonmail.com) Secure Email.

I would say the recommendation to use AccountingMax does not apply for bridges. It's just a subjective impression but there are often people complaining that most bridges they get handed out don't work or stop working after a short time. Some of these people end up believing that they are unable to use Tor at all from their location, because their adversary successfully detected the bridge. (Which might be true in some cases.) In order to avoid confusion for people who depend on using bridges it seems to make more sense to limit the bandwith instead.
