Running tor in VPS - keep away snooping eyes
by Kali Tor 03 Jul '14

03 Jul '14

All, Are there anything special that needs to be done to make sure that Tor nodes running inside VMs (VPS) is protected from snooping eyes? Since there is hardly any data at rest I am assuming not, but then, what do I know!:) -kali-

Why is UFW bllocking allowed TOR traffic?

I was monitoring UFW today and noticed that it was periodically blocking allowed TOR traffic. any ideas why from those with more experience than I? toradmin@IrvineTorExit:~$ sudo ufw status Status: active To Action From -- ------ ---- 22 ALLOW Anywhere 9001/tcp ALLOW Anywhere 9030/tcp ALLOW Anywhere 80 ALLOW Anywhere 22 (v6) ALLOW Anywhere (v6) 9001/tcp (v6) ALLOW Anywhere (v6) 9030/tcp (v6) ALLOW Anywhere (v6) 80 (v6) ALLOW Anywhere (v6) toradmin@IrvineTorExit:~$ sudo tail -f /var/log/syslog | grep DPT=9001 Jun 22 15:38:12 IrvineTorExit kernel: [ 2159.246977] [UFW BLOCK] IN=eth0 OUT= MAC=04:01:1b:5e:9a:01:28:8a:1c:64:cf:f0:08:00 SRC=92.108.200.200 DST=188.226.199.250 LEN=52 TOS=0x00 PREC=0x00 TTL=120 ID=10392 DF PROTO=TCP SPT=52000 DPT=9001 WINDOW=16652 RES=0x00 ACK URGP=0 Jun 22 15:38:12 IrvineTorExit kernel: [ 2159.246988] [UFW BLOCK] IN=eth0 OUT= MAC=04:01:1b:5e:9a:01:28:8a:1c:64:cf:f0:08:00 SRC=92.108.200.200 DST=188.226.199.250 LEN=52 TOS=0x00 PREC=0x00 TTL=120 ID=10396 DF PROTO=TCP SPT=52000 DPT=9001 WINDOW=16652 RES=0x00 ACK URGP=0 Regards, Jeff

FYI: Tor-Ops Meeting in Vienna
by MacLemon 02 Jul '14

02 Jul '14

Hoi! Yes, this is a crosspost of tor-talk, please be gentle. There will be a Tor-ops meeting on Thursday, 2014-07-03, 19:00 at the Metalab[0] in Vienna/Austria. The meeting was planned way before the recent rulings in Austria became known but they will be discussed for certain. The actual purpose of the meeting shall be to finally found a Torservers.at organisation (German word: Verein) in Austria that works on running nodes in the public interest as well as exchange know-how and best practice on running relays, bridges and exits. So in case you're in Vienna, please join! Best regards MacLemon [0]: http://metalab.at/wiki/Lage "How to get to Metalab"

Bandwidth usage for an established relay node
by Kali Tor 02 Jul '14

02 Jul '14

Hi all, Curious as to how much bandwidth a stable, well established relay node will chew through in a month on an average? Anyone has any figures? -kali-

optimize performance of a relay running on a VM
by s7r 02 Jul '14

02 Jul '14

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I have multiple relays running on the following systems: - - vmware vsphere virtualization technology - - 100 mbps port - - 1GB dedicated RAM - - 2.6 Ghz 1 core CPU dedicated - - OS: FreeBSD 10.0 Release amd64 or Debian Stable - - DO NOT KNOW IF I HAVE AES-NI SUPPORT OR HOW TO ACTIVATE IT (?) Currently atlas shows 3-4-5 MB/s advertised bandwidth for these relays. Arm shows between 600 and 1200 concurrent circuits (total of inbound, outbound and exit) and average traffic consumption is 5-6 TB per month (total both download and upload). I think this can be improved, but how? The servers have only purpose Tor, there is nothing else running on them and there is no bandwidth cap or throttling. Suggestions?

Re: [tor-relays] One IPv4 address, 1Gbit connection
by Tim 01 Jul '14

01 Jul '14

Tom, Why not run multiple tor relays on different ports on the same IPv4 address? For example, you could run 6 relays on 6 different ports on your IPv4 address (6 x 180 Mpbs > 1 Gbps). This would also utilise your 4 cores much more efficiently than running 2 relays (each relay will only ever use 1 core for most operations).

New Tor node operator hibernation question
by pandemicrelay＠hushmail.com 01 Jul '14

01 Jul '14

Hello, I am a new Tor relay operator, and have setup my first relay. It's been running as a Tor middle relay for about 10 days now, and it's been running solid. It has the stable, guard, fast, running, and valid flags. I have my AccountingMax quota set to start at the first of each month at midnight. However, just past midnight on 07-01 Tor said it was going to hibernate until 07-05. This had me confused as I was only about half way through my monthly quota setup in AccountingMax for June, and my hosting provider reset the data on the first at midnight. I read the manual page about AccountingMax again, and it appears this may have been normal behavior. However before I read the manual page, I forced my relay to wake up out of that hibernation. It appears to be operating normally right now. However, I am wondering if this will cause any issues this month, or in future months? Also, can someone explain if the hibernation of 5 days was normal behavior to begin with. Thank you
