running Tor relay live with AddressSanitizer
by starlight.2013q4＠binnacle.cx 28 Jun '14

28 Jun '14

Has anyone tried running a live relay with an image built using GCC 4.8 and -fsanitize=address? AddressSanitizer documentation says it should be no worse than about x4 on CPU and typically about x2, so it looks reasonable to try. I'm seeing peak CPU of about 7-8% of a 2.2GHz AMD core. I'd probably create a static build, with 'libevent' and 'tor' compiled using -fsanitize=address -O1 -fno-omit-frame-pointer -g per the Google documentation and 'libz' compiled normally since 'zlib' is stable and mature. Any thoughts or experience? Thanks

Need help to get TorDNSEL compiled
by BlueStar88 26 Jun '14

26 Jun '14

Hi there, today I've read about the outage at "check.torproject.org". Since my torcheck-service "torcheck.xenobite.eu" needs the underlying TorDNSEL feature I'm trying to get this to work on my host. Like this I won't need to query the TorDNSEL-part of "check.torproject.org" anymore. I'm not into programming and do not know anything about haskell, c++ and such. So be patient with me on such matters. ;-) I've DL'ed the code from the internet website mirror [2]. I've prepp'ed all the dependencies using lucid binary packages: ghc6 6.12.1-12 libghc6-mtl-dev 1.1.0.2-10 libghc6-network-dev 2.2.1.7-1 libghc6-time-dev 1.1.2.4-2 libghc6-hunit-dev 1.2.2.1-2 libssl-dev 0.9.8k-7ubuntu8.15 libghc6-stm-prof 2.1.1.2-5 libghc6-binary-prof 0.5.0.2-1 First error I got on compile attempt was: src/TorDNSEL/Main.hs:81:21: parse error on input `#' That was quite easy thought: import GHC.Prim (Addr#) I deleted the '#' hopefully making it correct this way. Next error is some numbers too high for me now: src/TorDNSEL/DeepSeq.hs:20:7: Could not find module `Data.ByteString': It is a member of the hidden package `bytestring-0.9.1.5'. Perhaps you need to add `bytestring' to the build-depends in your .cabal file. Use -v to see a list of the files searched for. The libghc6-bytestring-dev-0.9.1.5-125af ist installed by it's main package ghc6 6.12.1-12. Any ideas? Or are there some binary packages for TorDNSEL around, to make this more easy for me? :-P Thanks, BlueStar88 [1] https://blog.torproject.org/blog/tor-check-outage-03-and-04-july-2013 [2] https://www.torproject.org/tordnsel/dist/tordnsel-0.0.6.tar.gz

Setting up AWS cloud-relay - don't reserve expensive storage!
by Nick Sheppard 31 Mar '14

31 Mar '14

Hi all, I set up an AWS EC2 cloud Tor relay a month ago and made an expensive mistake. Perhaps others may learn from my example! I followed the instructions on the tor-project website, and found that it actually is quite a simple process, as it says. I did notice that the AWS setup screens I was seeing were different from the screenshots on the website, but they were asking me similar questions so I just went with the defaults where the website said "No changes". I didn't look closely enough. Everything went to plan and I watched the relay work for a month. However, on the AWS EC2 Management console I neglected to click on "Services" then "Billing" to see how much they were charging me. At the end of the month I got a bill for 120 dollars. And Amazon were quite right - they were charging me for the 1024 GB of storage I had accidentally asked for by not changing the default when I set up the instance. The first 30 GB were free, the other 994 I was paying for. And I was only actually using 1.5 GB ... There doesn't seem to be any way of shrinking the storage of an existing instance (though it can be expanded, now, with EBS, Elastic Block Storage), so I had to terminate it (which deletes the storage) and create another instance with a more reasonable 10 GB (of which df tells me I'm now using 11%). So ... if you've recently set up an AWS EC2 cloud relay with the Tor AMI, check your storage, and your billing! I think the option to specify your storage amount (with its default of 1024 GB) may have been introduced when AWS introduce EBS instead of just instance-backed storage (which may have defaulted to the size of the AMI??). In any case, I think the tor-project website AWS screenshots urgently need to be changed to reflect the current setup procedure, with a warning not to accept the 1024 GB default and an explicit recommendation about the amount of storage to ask for (was my guess of 10 GB reasonable?). Oh well, I have gained 100 dollars worth of wisdom from the episode. My way of "Don't look too closely, and hope for the best at the end of the month" was *not* a good idea. Nick Sheppard

When my bridge uses only the same few MBs each day, i guess it isn't used at all right? Is there a simple way to ensure it is in bridgeDB and functioning as it should? thanks, martin

Problem installing latest tor on a raspberry pi (ARM arch).
by aowenson＠neomailbox.ch 30 Dec '13

30 Dec '13

I was directed to this mailing list by a user on #tor IRC, so I'm hoping it's ok to ask for help here. For the past 2 to 3 months I've been running tor on my pi without any problems. The repository has been great, pulling out the correct ARM binaries, and it setup fine. This morning I tried updating the software, but the step "Checking if tor configuration is valid" fails; there are also 2x seg faults in the terminal output, not sure if this is a repository issue (fetching an x86 binary instead of ARM). The terminal output is here: http://pastebin.com/9Re2jrRe.

Re: [tor-relays] tor-relays Digest, Vol 35, Issue 25

i don't know, who knows how tor-weather sends the t-shirt e-mail. i took a look at the code and found that the mail is sent after 1464 hours of uptime (=61 days), checking every hour. according to this the downtime due to updates is really not that relevant. i'd guess that there are approx. 3 or 4 updates in the required 2 months, which would "cost" you an equivalent amount of hours. i don't think that it matters whether you get your mail 3 or 4 hours later. so i think the algorithm is fine.
