First time configuring a bridge - no log - doesnt work
by David Strappazon 03 Nov '19

Hi, I want to configure a tor obfs4 bridge on a raspberry pi 3B+. My system is Kali Linux. I followed this documentation: https://community.torproject.org/relay/setup/bridge/debian-ubuntu/ Actually, when i want to check the log in /var/log/tor, the folder is empty. TOr is running but nothing happens. here's my torrc file : RunAsDaemon 1 BridgeRelay 1 Log notice file /var/log/tor/notices.log Log debug file /var/log/tor/debug.log Log notice syslog Log debug stderr # Replace "TODO1" with a Tor port of your choice. This port must be externally # reachable. Avoid port 9001 because it's commonly associated with Tor and # censors may be scanning the Internet for this port. ORPort 4433 ServerTransportPlugin obfs4 exec /usr/bin/obfs4proxy # Replace "TODO2" with an obfs4 port of your choice. This port must be # externally reachable and must be different from the one specified for ORPort. # Avoid port 9001 because it's commonly associated with # Tor and censors may be scanning the Internet for this port. ServerTransportListenAddr obfs4 0.0.0.0:1234 # Local communication port between Tor and obfs4. Always set this to "auto". # "Ext" means "extended", not "external". Don't try to set a specific port number, nor listen on 0.0.0.0. ExtORPort auto # Replace "<address(a)email.com>" with your email address so we can contact you if there are problems with your bridge. # This is optional but encouraged. ContactInfo ################# # Pick a nickname that you like for your bridge. This is optional. Nickname RageAgainstTheMachine ExitPolicy reject *:* I've tried to check everything but i can't find why it doesn't work. Any help / advice would be appreciated.

I'm curious how to interpret the curves as seen in the attachment. The measurment were made at a stable fast relay in the past. -- Toralf

Multiple Tor instances
by nottryingtobelame＠protonmail.com 02 Nov '19

I have read that it is possible to run multiple bridges on the same IP using different ports and multiple instances of Tor. If this is the case, is there a guide, or can anyone provide instructions, for how to setup multiple instances of Tor on the same machine? Thanks in advance.

Issues reaching gigabit relay speeds
by Mitar 01 Nov '19

01 Nov '19

Hi! I have a gigabit connection and I am trying to utilize it as much as possible as a Tor relay. When I try various speed tests I get on the machine speeds close to gigabit, but when running Tor, I do not achieve anything close to it. I even started two Tor nodes on the same machine/connection, see here: https://metrics.torproject.org/rs.html#details/567E9785458C605E59202755C748… https://metrics.torproject.org/rs.html#details/4CF9BAEB0DE6D7230D6B7DA0FF42… The utilization of the machine is pretty low, top returns: top - 20:27:33 up 4 days, 23:01, 1 user, load average: 0.32, 0.28, 0.23 Tasks: 167 total, 1 running, 97 sleeping, 0 stopped, 0 zombie %Cpu(s): 1.6 us, 0.6 sy, 0.0 ni, 97.3 id, 0.0 wa, 0.0 hi, 0.5 si, 0.0 st KiB Mem : 3772912 total, 931336 free, 1574676 used, 1266900 buff/cache KiB Swap: 3900412 total, 3900412 free, 0 used. 1915568 avail Mem In configuration I have: RelayBandwidthRate 125 MB RelayBandwidthBurst 125 MB Interesting is that it seems each Tor daemon on same machine runs always around 5 MiB/s, when I started the second one, it just added to it with another 5 MiB/s. So it is somewhere else where is the bottleneck? What could I do to improve things here? To me it looks like more throughput should be possible?
