monitoring the relay : zabbix?
by krishna e bera 13 Oct '16

13 Oct '16

How do you monitor the tor relay server and the relay itself, on a remote box? Zabbix seemed to have less overhead and simpler setup than nagios or icinga, so i started to set it up. Then i saw the note on https://www.torservers.net/wiki/setup/zabbix that they do not use it anymore, and i am wondering what is wrong with it.

Politically correct?
by torserver＠datakanja.de 13 Oct '16

13 Oct '16

Hello list members, for simple - political - reasons, i began contributing otherwise wasted bandwith to the tor network about half a year ago. And i am reading this list. Lately, there has been a discussion (Intrusion Prevention System Software - Snort or Suricata), that brought up some opinions about tor, more or less focused from a technical point-of-view. Interesting to me (the noob, that i am) was the belief, that tor was ok (as some seem to think). I am very much less optimistic: >From the information, i can gather on my own personal computer, i can see, that almost every operating system sends out greetings to servers in akamai's reach, a company that happens to have contracts with microsoft and whatnot. Reading about their business, i find every reason to believe, that the time to fight for anonymity on the net is long gone, that security - even from their perspective - needs more resources than any individual will ever be able to have at its disposal. Also, i am aware of the possibility to get tracked by the telecommunication provider anytime and without me noticing it. My conclusion has been, that i am maybe 30 years too late in my activity to support tor - as a simple relay -. And the companies that seem to have most control over the internet (like google, akamai, and others) are in the process to control more and more of it, and only for that reason are fighting against malware like viruses and bots, and of course also fighting tor (by using honeypots as well as intrusion into the community to get as much information as possible about the people trying to hide in anonymity). This seems to be so true to me, that i begin to feel _guilty of nourishing false hopes_, that any individual could feel safe by using tor, irrespective of where and how legitimate/needed their requests are originating from. Seriously, i am beginning to think, that tor may be somewhat outdated nowadays, basically operating on old assumptions, about how the net was organised merely a decade ago. And not taking into account the reality of today, where our little community may not be all too useful any longer. Hard to hide some disappointment, as i used to be a developer many years ago, and find that no one - apart from myself - refuses to cooperate in the process of accumulating data, which provides the basis for semi-automated analysis later, and help some authorities to excert power and control over the population living on this planet. As my son very correctly said (btw: on his mobile! ;-)) : "Today, life begins, where there is neither computer nor electricity, but meeting with friends." ...until the earth observing satelites will be able to discern individuals. :-( Can anyone get me out of this pessimistic viewpoint? If not, i am seriously reconsidering the futile attempt to engage into offering something to the net, that could lead to unveiling users activities opposed to what tor seems to promise. Sorry for thinking out loud, but seriously worried about my own simple-mindedness. The operator of "NewTorKidOnTheBlock"

OBFS4 Bridge
by pvr6＠sigaint.org 13 Oct '16

13 Oct '16

Have been running an obfs3 bridge for a while. Since I was building a new Debian server wanted to add obfs4, but when I configure TBB to point to the obfs4 port [Z] I get "general SOCKS failure" in the TBB log. Changing it back to use obfs3 and port [Y] works fine. How can I fix it so obfs4 works too? Here are the relevant lines from torrc: --- ORPort [X] BridgeRelay 1 PublishServerDescriptor bridge ServerTransportPlugin obfs3 exec /usr/bin/obfs4proxy managed ServerTransportListenAddr obfs3 0.0.0.0:[Y] ServerTransportListenAddr obfs4 0.0.0.0:[Z] ExtORPort auto --- If I do netstat -pan, I see obfs4proxy is listening on both ports on all interfaces. I tried to add "--log-file logfile" after /usr/bin/obfs4proxy in torrc but then it wouldn't start the proxy at all. I'm not finding any other log messages showing a problem. Tor's log is clean, just shows it starting both proxy instances (which netstat confirms.) Obfs4proxy is the packaged version 0.0.6. Not sure where else to look or change. I'd like to get it working but have commented out the obfs4 line for now.

Running tor on OpenBSD with hardware acceleration
by Farid Joubbi 12 Oct '16

12 Oct '16

Hello, I have a relay running on OpenBSD. LibreSSL that comes with OpenBSD does not have support for hardware acceleration. I get this when I start tor: "[notice] We were built to run on a 64-bit CPU, with OpenSSL 1.0.1 or later, but with a version of OpenSSL that apparently lacks accelerated support for the NIST P-224 and P-256 groups. Building openssl with such support (using the enable-ec_nistp_64_gcc_128 option when configuring it) would make ECDH much faster." How do I enable support for hardware acceleration? My guess is that I have to compile and install OpenSSL, then compile Tor to use the new OpenSSL. Does anyone here have any experience with this on OpenBSD? Anything that I have missed and should be aware of? Thanks.

Moving multiple instances to another VPS
by pa011 12 Oct '16

12 Oct '16

I have to move a multiple instances Exit from one VPS to another. Apart from creating the same instances on the new machine with **tor-instance-create** I would then just copy the whole directory /var/lib/tor/keys to the new VPS - or should I copy all /var/lib/tor/ to not miss anything from the original one? Am I miss anything else? Thanks Paul

Yes. Every abuse ticket is a person answering that abuse ticket instead of helping a customer who is potentially paying for support. It's also that some of the abuse emails can be quite threatening (e.g. blacklisting the entire /24 or reporting the "crime" to local Police etc) some of the smaller ISPs can get intimidated by those threats. > - to whom else do ISP's have to report what they are doing with received > abuses?

Depends on the ISPs policies / any applicable laws. (In the UK and at least as far as my ISP is concerned; no-one) > - can an ISP loose its license (with too many or badly handled abuses)? AFAIK; No. In the UK I guess one could appeal to Court if an ISP wasn't preventing its network from being used to your detriment but I'm not sure how far you'd get. > - are there any regulatory burdens for them - if so which ones? Yes. Lots depending on the country. > - are ISP's treated different in different parts of the world? Very much so.

'No space left on device' glitch causing log failure
by Geoff Down 10 Oct '16

10 Oct '16

Hi all, these are the last entries in my log, but my bridge is still listed on Atlas and client functionality is fine. Latest stable version on OSX10.4. Needless to say, the disk is not full and 'tor' can write to that directory just fine now.

tor relay and syslog logging
by Dr. Who 09 Oct '16

09 Oct '16

I'm trying to log locally (notice.log) and to a local syslog-ng server. It doesn't seem to work. I get no messages at all to my local syslog server. When I try to log some testlines manually (even as the tor system user) it seems to work. As I understood the configuration I can have multiple "Log " lines without problem, right? A test like: logger -p daemon.notice -t tortest Testing generates the expected lines in /var/log/messages What facility is used by tor when logging to syslog? I didn't find that information. System is a standard current debian 8.6 with tor Tor 0.2.8.8 (git-8d8a099454d994bd), the two Log-Lines are: Log notice file /var/log/tor/notices.log Log notice syslog Any idea what might be missing?
