https://globe.torproject.org/#/relay/9DCF76179FCF47224D235ECD4A6165FED22ECE… So, i am running exit node. My provider send me an email .. "This IP is infected with, or is NATting for a machine infected with s_downloaderbot-mxb" Any idea what can i do with this problem ? Now i can see my IP in my server exit policy ... After my "delist action" is clean .. http://www.senderbase.org/lookup/ip/?search_string=37.157.192.208 I need just wait ? And all outgoing packet from my server still droped ? Thanks ..

comparing tor patch levels on different OSes
by Nusenu 30 Mar '15

30 Mar '15

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 I wanted to know whether a particular OS tends to be more likely running outdated* tor releases than another. In case others are interested as well, here is the answer. OSX, OpenBSD and Windows are more likely running outdated tor releases than FreeBSD or Linux. Probably not really surprising.. A more detailed answer: (ordered from bad to better) | OS | outdated_fraction | outdated relays | outdated_cw_fraction | +--------+-------------------+-----------------+----------------------+ | Darwin | 24.6154 | 16 | 0.03 | | NetBSD | 22.2222 | 2 | 0.00 | | OpenBSD| 21.8750 | 14 | 0.05 | | Windows| 17.2189 | 291 | 0.01 | | FreeBSD| 9.1743 | 20 | 0.15 | | Linux | 8.8392 | 597 | 4.29 | (based on onionoo data from 2015-03-27) If you are missing an OS (like SunOS) in the list, than this means that it does not run any outdated release at all (outdated_fraction=0%). *) actually it is about whether the relay uses a recommended version as defined by dir auths https://consensus-health.torproject.org/#recommendedversions I "added" tor 0.2.7.x to the list to avoid flagging bleeding edge relays as outdated. -----BEGIN PGP SIGNATURE----- iQIcBAEBCgAGBQJVGKLtAAoJEFv7XvVCELh00SwQAJ9KR0DsZ/SaeAJTjbHg2rkU yD7vuyxnJuenoQKkm2IYRTUwKbqPMgLcHqVWGp6y84qMQQMlqLcUnpu11D/6KgGY N6TtpK7qmfploA64/34whQjFUf5mh8++9LjsdyrY3DkCv/6izz01t9KCwev0S40r Ik/2o3bE/v6Yhwrs1jL1kzm+ekTHHj21y6HOQVt9Bbe0Myfqo6jaqcd6Ilt2PDAX FoM5MqWNtrOLbWs5wYesZv6OTAvFGKx5GG0/6sNu/t5R9Z6yk/kkQNWVg87EGyaQ PNIwhXI7lnou4tuYgekqBM9TAY94im6EC789Q3uLj2q/nGzWNcjPpHU+1XCVtSeH dFnAZ/LeKVWMkUr2k08xNegsiN32QizPYW+2EMLpPml9cubTvP+4Y/YVx6Z1RNA+ eg1y6kd5l3ht97WOTTEXe6Wvl1AjHHpW5wGrd36+wpy40Ac9IlJqx2Qei4XrmWDN is9PUDqWCiMRQJCs9WVOKh0dgrdKve2/ipJB4i3O8viN/yzh9VXmzaJXqYa7Dkct CTW90uzVOQ/zM8usGkVJEgef9ICjxKqsPWQnhK68reHPbxZasOVTJ9EsCQZhPBeI MoslvWS/VvgFQ/Wvgj2zjS4LXieNbZMoPnX/SLC5dHyjs6WjGeOFgNslQJwcBNGe Q29d8/zH8q4tKBU5RpI5 =bbrP -----END PGP SIGNATURE-----

Installing obfs4 on Raspberry Pi bridge
by jchase 29 Mar '15

29 Mar '15

Hello, I run a bridge on a Raspberry Pi running Debian Wheezy and tor 0.2.4.26 . I have obfs3 installed and would like to upgrade to obfs4. So far this has not been possible. If I understand it correctly, my best bet is to update to tor 0.2.6.x and then install obfs4. Let me know if I'm wrong. And if I'm right, what is the easiest way to do that? Thanks, J. Chase

Interesting and useful tips s7r! Thanks for sharing. Props to all! undertuga -------- Original Message -------- Subject: Re: [tor-relays] Installing obfs4 on Raspberry Pi bridge Time (GMT): Mar 28 2015 22:20:09 From: s7r(a)sky-ip.org To: tor-relays(a)lists.torproject.org -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Hi, obfs4 will not run on 0.2.4.x , you need at least 0.2.5.x or 0.2.6.x First, upgrade your Tor. You can use torproject.org repositories. If you are running wheezy: 1. Add the repository: # echo "deb http://deb.torproject.org/torproject.org wheezy main" >> /etc/apt/sources.list 2. Add the signing key: # gpg --keyserver keys.gnupg.net --recv 886DDD89; gpg --export A3C4F0F979CAA22CDBA8F512EE8CBC9E886DDD89 | apt-key add â 3. Install keyring: # apt-get update && apt-get -y install deb.torproject.org-keyring Now upgrade your Tor, an apt-get -y install tor would upgrade to 0.2.5.1 1. You can install obfs4proxy from deb.torproject.org too: # echo "deb http://deb.torproject.org/torproject.org obfs4proxy main" >> /etc/apt/sources.list # apt-get update && apt-get -y install obfs4proxy Now, modify your torrc to enable the obfs4 transport. Make sure you also add ExtORPort auto in torrc so it will report some useful statistics. obfs4proxy also supports obfs3, and some users still use that, so if you can be an obfs3 and obfs4 bridge at the same time (requires just one more open port) it would be great. Sample torrc entry for enabling obfs4 and obfs3: ExtORPort auto ServerTransportPlugin obfs3,obfs4 exec /usr/bin/obfs4proxy ServerTransportListenAddr obfs3 [::]:port ServerTransportListenAddr obfs4 [::]:port To make the bridge even better, you can bind obfs3 and obfs4 to lower ports (< 1024), if you have them free, such as obfs3 on 80 and obfs4 on 443 (for example). This will help users behind really restrictive firewalls who only allow connections on few ports. You can easily do this with libcap2-bin package: # apt-get -y install libcap2-bin # setcap 'cap_net_bind_service=+ep' /usr/bin/obfs4proxy To make this persistent after a reboot, edit the /etc/rc.local file and add this line before 'exit 0': setcap 'cap_net_bind_service=+ep' /usr/bin/obfs4proxy Hope this helps. If you don't want to use deb.torproject.org, everything required is also included in raspbian main repo: http://archive.raspbian.org/raspbian/pool/main/t/tor/ http://archive.raspbian.org/raspbian/pool/main/o/obfs4proxy/ http://archive.raspbian.org/raspbian/pool/main/libc/libcap2/ If you want to use raspbian repo, simply ignore the lines where you add deb.torproject.org to your sources.list file and just upgrade, install the required packages and modify your torrc file.

Monitoring my bridge I

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Since March 24 globe has been showing no bandwidth usage for my bridge. At the same time I'm measuring non-zero bandwidth locally. These local measurements run about Received ~ 10 x Sent bits. The bridge is connected to live circuits as per atlas. I've had erratic traffic since the powers that be have decreed that bridges be locked into a small number of entry nodes for long periods. when Received ~ Sent & I see traffic, interspersed with periods where Received >> Sent & no traffic. I don't *think* globe is an error, since I'm not reading any client traffic, only pokes from entry nodes. Here is my configuration, which worked fine previously: BridgeRelay 1 ## fteproxy configuration ClientTransportPlugin fte exec TorBrowser\Tor\PluggableTransports \fteproxy --managed # obfsproxy configuration ClientTransportPlugin obfs2,obfs3,scramblesuit exec TorBrowser\Tor \PluggableTransports\obfsproxy managed ## It doesn't seem to matter whether I enable the above portable transports or not.

Hardware specs for Tor Relay
by yl 26 Mar '15

26 Mar '15

Hello, I clicked myself a cheap vserver 20 days ago and it runs Tor since then. I mainly did this to play a bit with the relay, try around and so. I took over another relay a while ago, an exit, I don't want to try around on that. It runs well, I got about 4,4 TB data up AND down since then, I have it running with 20-40Mb/s on a 100Mb/s connection (according to the hoster 100Mb/s), it runs as a non exit. CPU load it pretty high all the time according to arm it's about 80-100%, but with htop I can see that only one core of the CPU is busy, the others are not. I figured that the CPU is so busy because the vserver doesn't have AES-NI, which I confirmed by some command I run (forgot the command). So I thought I might wanna move that relay to another server, maybe at the same hoster to get higher data transfer. What hardware specs do you have and is my assumption correct with the AES-NI being one part of the bottleneck? Thanks yl

Did you ask them if you can get it ? I had a VPS a while ago and they said "we disabled that for compatibility reasons" but if you want it we will turn it on. And they did it for free :-) > > So I thought I might wanna move that relay to another server, maybe at > the same hoster to get higher data transfer. > > What hardware specs do you have and is my assumption correct with the > AES-NI being one part of the bottleneck? It is the no. 1 bottleneck from my experience. I still hope that we are going to see the crypto-multithreading feature at some point in the future. -- Sincerely yours / Sincères salutations / M.f.G.
