ansible-relayor, how to ?
by Petrusko 01 Apr '18

01 Apr '18

Hey! I'm planning to try the "ansible-relayor" to deploy some Tor relay instances. If I'm not wrong, it's a main goal ? 2 instances / IP... (soooory for being really noob about this!!!) But I'm lost... not found a tutorial, step by step, you know the tutorial so loved by all noobs! For now, on a fresh Debian8 install, there are : - tor 0.2.9.8 (fresh install from depo, client is ok when opening log file) - ansible - ansible-galaxy install nusenu.relayor - git clone https://github.com/nusenu/ansible-relayor (the folder is stored in my /home...) Will it configure (automatically) many torrc file per instance ? +every key files /relay ? (I'm not too much lost!) Do have I to do this install on every server built ? Or relayor can manage few servers on different locations ? Command lines list use this tool if available ? Many thx for help !!! (and hard work for this tool :) -- Petrusko C0BF 2184 4A77 4A18 90E9 F72C B3CA E665 EBE2 3AE5

Relay uptime versus outdated Tor version
by K. Besig 02 Oct '17

02 Oct '17

One of my relays has over 416 days of uptime, which I'm very proud of, however it's running an outdated version of Tor. I should probably already know the answer, but it seems to me I would have to stop the tor service to update the relay. Would I in fact lose my uptime or would it be seamless? Thanks for the response

Force OpenSSL AES-NI usage on a VPS without the AES CPU flag passthrough
by Roman Mamedov 07 Sep '17

07 Sep '17

Hello, Today I found that it is possible to force OpenSSL enable the use of CPU AES acceleration even if it doesn't detect the "aes" CPU flag. Many VPS hosts configure their hypervisors in a way that does not have the flag passed through into VPSes, even though all their host nodes surely have CPUs with support for AES-NI. In my experience hosts have not been forthcoming in reconfiguring their systems to include that flag passthrough. But it turns out we can force OpenSSL to believe AES is supported, even if the CPU does not report it. This can be done with the "OPENSSL_ia32cap" environment variable. Searching around, all I found was scenarios to use it for disabling AES-NI (for testing), e.g.: https://mjanja.ch/2013/11/disabling-aes-ni-on-linux-openssl/ I believe the syntax used there applies "xor" over the real flag values, e.g. OPENSSL_ia32cap="~0x200000200000000" to disable AES. But what if you need to force-enable it. Turns out the syntax working for that is simply: OPENSSL_ia32cap="+0x200000200000000" Let's take one VPS box with the aforementioned problem. # cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 13 model name : QEMU Virtual CPU version 1.5.3 stepping : 3 microcode : 0x1 cpu MHz : 1695.729 cache size : 4096 KB physical id : 0 siblings : 1 core id : 0 cpu cores : 1 apicid : 0 initial apicid : 0 fpu : yes fpu_exception : yes cpuid level : 4 wp : yes flags : fpu de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pse36 clflush mmx fxsr sse sse2 syscall nx lm rep_good nopl eagerfpu pni cx16 hypervisor lahf_lm bugs : bogomips : 3391.45 clflush size : 64 cache_alignment : 64 address sizes : 46 bits physical, 48 bits virtual power management: As you can see "aes" is not present. Testing OpenSSL speed in the default configuration. # openssl speed -elapsed -evp aes-128-gcm ... type 16 bytes 64 bytes 256 bytes 1024 bytes 8192 bytes 16384 bytes aes-128-gcm 32332.17k 40365.80k 42265.77k 42376.19k 43196.42k 43401.22k And now we force AES hardware acceleration usage: # OPENSSL_ia32cap="+0x200000200000000" openssl speed -elapsed -evp aes-128-gcm ... type 16 bytes 64 bytes 256 bytes 1024 bytes 8192 bytes 16384 bytes aes-128-gcm 59047.07k 104467.39k 141712.21k 151093.93k 158321.32k 156827.65k Almost 4 times faster! For Tor this leads to higher bandwidth utilization and lower CPU usage (which will actually make your VPS host happier :) But how to apply that to Tor? Well, for some initial testing I just chose to add the following line to /etc/init.d/tor (not using systemd here), right after "#! /bin/bash": export OPENSSL_ia32cap="+0x200000200000000" (but this will get overwritten and removed by the next Tor version upgrade). Seems to work just fine, my CPU usage is half of what it was before, at similar bandwidth levels. So now it has headroom to ramp up further. A word of caution, firstly always test as shown above to verify that it works. I believe if the underlying CPU actually doesn't support AES, all programs trying to use it, including "openssl speed", will crash outright, with an incorrect instruction error, or somesuch. So there is no risk to jeopardize encryption strength or security of Tor. Also even if it works now, it may stop working down the line if the host migrates your VPS to a node with older CPU, one which doesn't support AES. But migrations of customers between do not happen very often, and in fact all CPUs used today in a hosting environment should support AES, as that's been implemented in server (and even desktop) CPUs a very very long time ago. (Apologies for double-post, I realized tor-relays should have been the better place to post). -- With respect, Roman

Re: [tor-relays] DIR Port. and NATO

Roger, thank for the answer. Reason of no DIR port will be Accounting Max Enabled, although every unlikely I would reach the max I set, I use those settings to give me instant total usage within ARM While searching for some suitable wording if I ever get abuse complaints again, and searching the legal risks within Europe of Exits, I was rather surprised found NATO published a detailed appraisal of Tor.

Is that the reason not showing? Check out your logs as the relay starts. Look for a log message like log_notice(LD_DIR, "Not advertising Dir%s (Reason: %s)", dir_port ? "Port" : "ectory Service support", reason); Common reasons include "AccountingMax enabled" and "BandwidthRate under 50KB". In general, it's fine for Tor to decide not to advertise your DirPort. Everything else is still working fine.

DIR port on my relay and mini exit as being there on Atlas. The DIR port is open, indeed the DirPortFrontPage can be seen. Bandwidth is “fast” The exit is very limited in scope to avoid abuse claims, so few ports forwarded such as 443, but not 80. Is that the reason not showing? Gerry

Tor relay making normal internet unusable
by W Howard 30 Aug '17

30 Aug '17

Dear Group, I have some spare bandwidth and want to run an exit relay buy when I do the normal internet is so slow and I have to fill out so many captcha that it makes it unusable! Any ideas why? I think google etc block by default tor exit nodes. I was thinking about spinning up a vm and running tor on that. When I run as a bridge I don't see much traffic. Any ideas? Cheers!

OR banned?
by Marcus Danilo Leite Rodrigues 24 Aug '17

Hello. I was running a Tor Relay for the past month (fingerprint 71BEBB61D0D35234D57087D035F12971FA315168) at my university and it seems that it got banned somehow. I got messages on my log like the following: http status 400 ("Fingerprint is marked rejected -- please contact us?") response from dirserver '171.25.193.9:443'. Please correct. I was hoping to get some information regarding this ban and how I could correct whatever was done wrong in order to get my relay up and running again. Best wishes, Marcus Rodrigues.

Question I have is there anywhere where you can get a block of IP address or lease as I'm in the process of getting a 10/10Mb SHDSL service(No flaming data cap :-)) here in AU but I want an IP range that abuse questions can be forwarded to me. The service provider doesn't provide ARIN registration but said if I have my own block I can update the BG and manage it my self.

Thanx niftybunny, It's more political than anything. With the constant changes in policy driving censorship I feel that having a strong presence is important. At the moment there are 50 nodes in Australia with the fastest running at 357Kbs and only two exit nodes - fastest is 100Kbs. Its a reflection on the state of politics and the level of service that is provided by ISP's. Yes I could run more nodes in VMs around the world but at this stage I would like to investigate a strong presence here in AU.

Bandwidth Question
by Torix 23 Aug '17

23 Aug '17

Dear List, I run a middle node at home. I jacked up my bandwidth from 300/500 KB to 500/700 KB a fortnight ago, and my usage has more than doubled. I run it on Verizon FIOS at home; I'm looking at about 650-750 G/month estimate now from vnstat. I read that Verizon starts to take notice if I get to a TB/month, so I am asking for advice on easing this back if necessary. I can limit the daily bandwidth - or can I just ease down the bandwidth? Clearly each time I increased the bandwidth I got more connexions; would they drop off if I went back to my old bandwidth? I'm a little unclear how long it would take other relays to attach to other middle relays once they have found mine. The more general question behind this is: is it better to have a higher bandwidth for a limited time each day or a lower bandwidth up all day?

Found a provider that doesn"t seem to have a cap on data and it will cost me about five euros a month. Question I have is two fold. First I find that atlas.torproject.org sometime says the node is down but its running and connected. Secondly how dose the bandwidth throttling work. I have set it to 300kbits with 500kbit burst but I can see the in/out traffic staying over 1mb for large periods of time and bursting to 7/8mb. Its not a problem just curios.

significant rise in fail2ban alerts for ssh abuse
by Dirk 21 Aug '17

21 Aug '17

Dear all, we receive a significant rise of ssh login abuse mails which reach us and unfortunately our providers. By significant I mean an amount that starts flooding our abuse inbox. All abuse emails are structured the same way and point to Fail2Ban as originator. Do we have just bad luck and someone uses our severs to brute force all of SSH out there OR is there a new Fail2Ban or Linux distribution release which fosters or enables this fail2ban abuse mails be default ? As far as I know the functionality of Fail2Ban is old. If there would be a Linux distribution which enables this I would like to talk to the maintainer and let him know that he at least tries to read the correct abuse entry from ripe instead of bothering our provider as well. For a limited time we will now reject port 22. But really do not like this solution. I would rather like to find out the source of this rise in numbers. best regards Dirk Example 1 ---- Dear Sir/Madam, We have detected abuse from the IP address 1.1.1.x, which according to a whois lookup is on your network. We would appreciate if you would investigate and take action as appropriate. Log lines are given below, but please ask if you require any further information.

End of Life Relays
by nusenu 19 Aug '17

19 Aug '17

Hello relay operator, Please note that recently (2017-08-01) a few tor releases reached end of life and are no longer maintained (no security and bugfixes) [1]. Please consider upgrading to a supported release if you are affected. To find out whether you are running an end of life tor release you can search for your relay nickname on [2] or on https://atlas.torproject.org. As of 2017-08-19 still >9% of the tor network run on end of life releases. thanks for running tor relays, nusenu [1] https://trac.torproject.org/projects/tor/wiki/org/teams/NetworkTeam/CoreTor… [2] https://nusenu.github.io/OrNetStats/eolrelays -- https://mastodon.social/@nusenu https://twitter.com/nusenu_

bwauth in testing
by Tom Ritter 19 Aug '17

19 Aug '17

After suffering the loss of maatuska's bwauth several months ago, we have re-provisioned it thanks to the gracious help from https://coldhak.ca/ It has completed an initial scan of the network[0] and is reporting its data here: http://198.51.75.50/bwauth/bwscan.V3BandwidthsFile This week I intend to flesh out the remaining aspects of the bwauth (debug logging, alerting to detect downtime, get a proper domain name, ssl cert, etc) as well as do some sanity checking on its output. If all goes well, I'll submit it to maatuska for inclusion at the end of the week. But I wanted to announce it here, both to give an update, and let the community take a look at its output and see if anything looks fishy. The bwauths themselves tend to disagree, partly because of the eb and flow of network speeds and partly because they are designed to (they all measure from different network vantage points) - but they ideally are in some sort of rough agreement. -tom [0] "Measured 99.7% of all tor nodes (99.6% of previous consensus bw)."
