Hello All, Anyone else notice onionoo and the tools that rely on it (globe.torproject.org atlas.torproject.org) seem to be down? -Jason

Others have had more luck, but mostly on Linux AFAIK. Do you perhaps have a system-installed OpenSSL 0.9.* which is lacking EVP_aes_128_ctr? See https://trac.torproject.org/projects/tor/ticket/13817 for a similar failure, due to the following issues: configure --with-openssl-dir= detects the wrong bin/openssl if "$OPENSSL_DIR/bin/openssl" isn't in the path before all other openssl executables. configure --enable-static-openssl requires LDFLAGS="$OPENSSL_DIR/lib":$LDFLAGS to link properly, at least on OS X. If you do run into runtime SSL errors, see this bug: https://trac.torproject.org/projects/tor/ticket/13816 teor pgp 0xABFED1AC hkp://pgp.mit.edu/ https://gist.github.com/teor2345/d033b8ce0a99adbc89c5 http://0bin.net/paste/Mu92kPyphK0bqmbA#Zvt3gzMrSCAwDN6GKsUk7Q8G-eG+Y+BLpe7w…

boost CPU on a Tor relay

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, A Tor relay currently going 33MB/s could go a lot faster but CPU is at 93% usage - this is the bottleneck.

Platform diversity in Tor network [was: OpenBSD doc/TUNING]

Absolutely. Not just due to OpenBSD's security positioning, but moreso from network diversity. Windows is its own world. But if you're a Unix admin there's no reason Linux should be deployed 20x more often than [Free/Open]BSD. It's ridiculously counter to meeting diversity goals, especially with bandwith weighting if one platform is getting grossly disproportionate traffic than another. Just pick one of the two BSD's and run it instead. FreeBSD in particular is well suited to the OS and network needs of Tor. And knowing how to admin more Unixes will serve any admin well. 5950 Linux 1593 Windows 173 FreeBSD 55 Darwin 44 OpenBSD 7 NetBSD 6 SunOS 4 Bitrig 2 GNU/kFreeBSD 1 DragonFly

doc/HARDENING Draft

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 I thought I'd share an initial draft of doc/HARDENING. Please share any opinions or contributions you have. This was written in a little more than an hour, so it's still a work in progress. However, in the spirit of prototyping before polishing, I thought I'd share early. Here's the relevant ticket: https://trac.torproject.org/projects/tor/ticket/13703 A specific topic of conversation is how much of the advice should be in the document itself as opposed to linked sources. It could also use more OS diversity. After reading it, you can probably guess which *nix flavors I'm familiar with.

Fast Exit Node Operators - ISP in US
by SiNA Rabbani 29 Nov '14

29 Nov '14

Dear Relay Operators, I noticed there are very few US based exit nodes in the network. And more and more people are jumping on the same set of AS numbers in Europe. I am not if the reason is lack of Tor friendly ISPs or people are just too freaked out about the summer of Snowden. I think it's very wrong to assume that EU countries are not part of the world-wide-wiretap, packets are going through a few internet exchanges anyways. I have been hosting/operating Faravahar (one of the authority directory servers) at Rethem Hosting (rethemhosting.net) for a couple of years now, and never had any issues. I also just brought up 2 exit nodes there: https://atlas.torproject.org/#details/A5B1C342B316C2AE5695B903CED18F619A836… https://atlas.torproject.org/#details/6FFCDF910C32D620FCC6EEF7A8A57F3E9A234… If anyone is interested in running fast Tor Exit nodes at Rethem Hosting. Feel free to contact me directly, so I can make proper referral/introductions. Rethem Hosting is also able to provide hosting In IceLand, but you get the most bang for your buck in the US datacenter. Thank you for contributing to Tor.

wild swings in Advertised Bandwidth
by jchase 23 Nov '14

23 Nov '14

Hi, I'm running a low-volume bridge on a raspberry pi. Globe.torproject says that my fingerprint is 1BCD3EBEFE17EEB86EEDE21D5E2DB8468E2864CF . I'm keeping an eye on myself and traffic via globe.torproject and my advertised bandwidth makes wild swings: one day its 56 kB/s and the next day it's 8 kB/s. When I read that "The minimum BandwidthRate setting is 20 kilobytes per second", I am confronted with the fact that 8 is less than 20 and it doesn't seem worth it keeping my bridge up and working. Why would a bridge make such swings in advertised bandwidth? And is there any good reason to keep the bridge up and working if it sinks to 8 kB/s? Thanks, J Chase

Decision on Dedicated Server for Exit Node
by Libertas 22 Nov '14

22 Nov '14

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 I've been looking for a budget dedicated server to host an exit node on, and the best option I've found is BalticServers. However, they're already listed on the GoodBadISPs wiki page, and because they're in Northeast Europe (Lithuania, to be precise) I'm concerned that their ISP already has more exit nodes than is healthy for network diversity. Is it a good idea to host another exit node there? If you think there's a better option, I'd appreciate it if you could tell me either publicly or privately.
