Worse throughput with 0.4.8.x, on a slow CPU
by Roman Mamedov 04 Mar '24

04 Mar '24

Hello, Ater upgrading from Tor 0.4.7.13 to 0.4.8.9, I get a much worse bandwidth numbers. The CPU is Atom C2338 with two cores at 1.75 Ghz. Multiple Tor instances are running to take advantage of both cores. On the older version it gets about 80+80 Mbit total in+out. On the new one the average is at most 45+45 Mbit. There are frequent periods where the bandwidth drops to 5-10 Mbit for 3-5 seconds, while all Tor processes continue to use 100% of both CPUs, then gradually climbs back up. Does anyone notice anything similar? Here's how it looks for a few days on 0.4.8 then a roll-back: ------------------------+-------------+-------------+--------------- today 461.94 GiB | 470.84 GiB | 932.78 GiB | 153.98 Mbit/s ######################################## 12/12/23 462.81 GiB | 475.67 GiB | 938.48 GiB | 91.12 Mbit/s ####################### 12/11/23 434.72 GiB | 443.08 GiB | 877.80 GiB | 85.23 Mbit/s ###################### 12/10/23 446.13 GiB | 459.56 GiB | 905.70 GiB | 87.93 Mbit/s ####################### 12/09/23 464.79 GiB | 473.17 GiB | 937.96 GiB | 91.07 Mbit/s ####################### 12/08/23 454.67 GiB | 463.48 GiB | 918.16 GiB | 89.14 Mbit/s ####################### 12/07/23 463.82 GiB | 472.84 GiB | 936.65 GiB | 90.94 Mbit/s ####################### 12/06/23 670.01 GiB | 680.55 GiB | 1.32 TiB | 131.13 Mbit/s ################################## 12/05/23 808.50 GiB | 817.32 GiB | 1.59 TiB | 157.85 Mbit/s ######################################### 12/04/23 854.09 GiB | 866.43 GiB | 1.68 TiB | 167.05 Mbit/s ########################################### 12/03/23 782.20 GiB | 799.00 GiB | 1.54 TiB | 153.52 Mbit/s ######################################## 12/02/23 805.18 GiB | 817.91 GiB | 1.59 TiB | 157.59 Mbit/s ######################################### 12/01/23 733.80 GiB | 745.35 GiB | 1.44 TiB | 143.61 Mbit/s ##################################### 11/30/23 742.48 GiB | 756.56 GiB | 1.46 TiB | 145.54 Mbit/s ##################################### 11/29/23 657.90 GiB | 673.66 GiB | 1.30 TiB | 129.28 Mbit/s ################################# In general, are there any tweaks to reduce relay CPU usage on a slow processor? I did seemingly most of what is possible, ethtool, iptables, sysctl, etc. How long before the Rust-based Tor will be ready for use on relays? -- With respect, Roman

bridges for Lox
by meskio 28 Feb '24

28 Feb '24

Hello, We are developing a reputation based bridge distributor called Lox[0] and are preparing to make a call for users to test it in Tor Browser Alpha. In order to do this, we need to have some new bridges that can be distributed by Lox. Do you want to give us a hand running a bridge (or few) for Lox? At the moment we're looking for 10 new bridges for Lox. Rdsys, the new bridgeDB, will not automatically assign bridges to Lox for now, but will instead accept bridges with the 'BridgeDistribution lox' configured in torrc. To set up a bridge for Lox, configure a normal obfs4 bridge[1] and simply include the following line in torrc: BridgeDistribution lox As Lox is only going to be released for testing, you might not see a lot of traffic on Lox bridges at the moment. However, these bridges will be very useful for us to improve Lox and see what works and what does not.

Tor Relay Automatic PMTU Testing
by pasture_clubbed242＠simplelogin.com 22 Feb '24

22 Feb '24

Greetings, I believe there is a larger sized guard relay that has been having MTU issues for about a week. All connections with packets above a certain size are dropped. This results in partially loaded or broken webpages, broken file downloads, etc. Do Tor directory authorities test MTU (implicitly by speed test?) when testing relays? Wondering if anyone else noticed this or if it would be handled automatically by dir authorities. Thanks all

VPS w/FDE suggestions?
by MRob 22 Feb '24

22 Feb '24

Hello- Im looking for <= $6/mo VPS suggestions for general non-tor server and also for tor. Some super-cheap hosts pre-install O/S and give root but I want to install O/S myself so can put in FDE. Hard to see which hosts can do this. I tried Linode before and yes, could get FDE ($5 1GB, 1CPU, 25GB, 1TB) Is IONOS any good? Can I get FDE there?? ($2 1GB, 1CPU, 10GB, ?TB) ($3 2GB, 2CPU, 80GB, ?TB) ($6 4GB, 2CPU, 160GB, ?TB) Others caught my eye: hudsonvalleyhost ($3.95 1GB, 1CPU, 25GB, 20TB) ($6.95 2GB, 2CPU, 50GB, 20TB) liquidweb ($5 1GB, 1CPU, 30GB, 1TB) digitalocean ($6 1GB, 1CPU, 25GB, 20TB) ovhcloud ($4.20 2GB, 1CPU, 20GB, 100Mbps unmetered) ($5.50 2GB, 2CPU, 40GB, 500Mbps unmetered) brownrice ($5.95 3GB, 1CPU, 10GB, unlimited)

Hi, So my relay at https://metrics.torproject.org/rs.html#details/79E3B585803DE805CCBC00C1EF36… is again saying it's new despite that it's been running for a few years now. Second time this has happened. Thanks. --Keifer

7000 concurrent connections
by snowmanonahoe＠skiff.com 20 Feb '24

20 Feb '24

Hello all, I'm interested in running a relay. I should meet all the requirements for a guard/middle, except handling 7000 concurrent connections, which I'm unsure of. The website seems to tell me to try it and see what happens, but what exactly am I watching out for? Is the router going to fail entirely, slow down, or something else? Thanks in advance.

Hi, with Tor version 0.4.7.x being EOL, the docker image for the webtunnel bridge deserves an update, as it still uses 0.4.7.13 ! Regards, C. -- Sent with https://mailfence.com Secure and private email

Getting spammed with 404 "Consensus is too old" warnings
by snowmanonahoe＠skiff.com 16 Feb '24

16 Feb '24

Hello all, Obfs4 bridge. Here is the exact warning text: Received http status code 404 ("Consensus is too old") from server 203.0.113.45:443 while fetching consensus directory. They appear in irregular intervals between 2 and 45 minutes. The heartbeat messages indicate the relay is working fine. The IP address is the same every time, and it's not mine. Anything to worry about?
