Auto-detect and enable IPv6 // Re: Please enable IPv6 on your relay!
by Roman Mamedov 22 May '15

22 May '15

Hello, > We still have a depressingly low number of relays that support IPv6 > (currently only ~120 of ~1900 relays). If your host supports IPv6, > please enable it, especially if you run an exit! This has to be done > explicitly. If you (supposedly) care so much, then can you please make it automatic? There is no need to explicitly put the ____IPv4____ address into the torrc. And there is no need to explicitly put the IPv6 address into the config file of virtually any other IPv4+IPv6 supporting software I can think of: web, mail, NTP, XMPP servers, those are all capable of automatically figuring out which IPs the host has. Can't think of any reason of why this has to be otherwise in Tor, aside from perhaps a certain lack of understanding of best IPv6 implementation practices from the Tor developers side and/or nobody simply giving much thought to this yet. I currently run 15 Tor relays, 14 of those IIRC are IPv6 capable. But since you did not bother to make enabling IPv6 in Tor anywhere near user-friendly [1], I am simply not going to bother pecking the IPs into each torrc individually. [ One of the practical reasons being that I sometimes need to migrate the Tor 'identity' (torrc + /var/lib/tor/*) between machines and providers with v4/v6 addresses obviously changing. ] Aside from migrations between providers, the requirement to specify the IP is also impractical in many other situations, e.g. my ISP at home provides only a __dynamic__ IPv6 subnet which changes to a different one with each new PPPoE session. [1] Ideally there should be no 'enabling' at all!!! IPv6 should be active by default, IF the relay has determined it is able to make a successful IPv6 connection with a dir-authority -- oh and also that's how you can discover the actual working IPv6 address to use; or at least with a simple "IPv6Relay 1, but certainly with no requirement of specifying the IP address in the config file. -- With respect, Roman

Leaseweb exit relay notice
by blaatenator 21 May '15

21 May '15

Hi all, FYI: Yesterday I got the notice below from Leaseweb. I picked them because Leaseweb is mentioned in the Good/Bad ISP <https://trac.torproject.org/projects/tor/wiki/doc/GoodBadISPs> post. Apparently a blacklist named SECTOOR added a whole IP block of Leaseweb to block my Exit relay. Since this list is used by some bigger corporations, it got some other customers in trouble and they asked me to restrict the mentioned ports. I understand the reasoning and can't blame them for asking my I guess (and since most relevant ports are not mentioned I guess it is not too bad), but I found it a bit weird that a whole subnet is being listed.

BWauth kookiness

Some possible fallout related to the earlier discussion [tor-relays] amount of unmeasured relays continuously rising since 2 weeks https://lists.torproject.org/pipermail/tor-relays/2015-May/007003.html My relay Binnacle 4F0DB7E687FC7C0AE55C8F243DA8B0EB27FBF1F2 has 9375 Kbyte (75 Mbit) of unfuzzy (no ISP traffic shaping) bandwidth, but in the last few days the BWAuths' opinion went from # gabelmoo # tor26 # moria1 # longclaw bw1-w Bandwidth=7382 Measured=7100 *bw2-w Bandwidth=7382 Measured=9330 bw3-w Bandwidth=7382 Measured=13700 GuardFraction=69 bw4-w Bandwidth=7382 Measured=23700 to bw1-w Bandwidth=9375 Measured=17100 bw3-w Bandwidth=9375 Measured=77900 GuardFraction=75 *bw4-w Bandwidth=9375 Measured=23000 * selected for consensus While it's flattering to be promoted to double the actual capacity, with the potential to go 8x, I suspect it's may not a great idea in the grand scheme of things. And to think at one time I was feeling short-changed. . . FYI BWauths Regards

Tor Consensus Weight Stuck at 20 (Even on Relay with "Stable" Flag)
by Neel Chauhan 19 May '15

19 May '15

Hi, I have a Tor relay (https://atlas.torproject.org/#details/342587A287603040A49BB364D72EAC0B6BC3D…) running from a FreeBSD server at my house on with a 5 megabit upstream connection. I have seen that lately, Tor's "Consensus Weight" value on this relay has not been going anywhere above (or below) 20. My relay has gotten the "Stable" flag, but yet didn't see it's consensus weight value rise. I decided to look at https://consensus-health.torproject.org/, and saw that two of the four bandwidth consensus servers, namely tor26 (86.59.21.38) and longclaw (199.254.238.52) don't seem to be calculating any consensus value for Tor relays in the last few days. Has anyone else been having this problem? And if the Tor consensus operators are reading this, (approximately) when would this problem get resolved? Thanks, Neel Chauhan

Tor relay/btc node script
by torelay 18 May '15

18 May '15

I've written my first script. It is to automate the process of setting up a tor relay/bridge (published or not) and a bitcoin full node (with hidden service url and/or clearnet ip) on a fresh debian os. The script is at https://github.com/mktx-code/relay-node. To write it I used a combination of the sky-ip tuts and random github codes for syntax and structuring. Please give me any comments criticisms. Appreciated.

Re: [tor-relays] Windows Tor Server Guide
by Ben Serebin 18 May '15

18 May '15

Hi there... 1st post (I figured after years of donating to EFF, I should run a tor relay). I've searched and read many posts on tor-relays and the best Windows Tor Server Guide I found was this below one by Rafael Rodriguez. A few questions, and apologies if they seem silly, but there is scant info out there for us Windows admins. - is a web server needed? - the below email post had the slashes stripped from the path entries which makes it tricky to follow (talk about an annoying mail-list process). Overall, throw all the files in a single dir? - before I load it as a service, once all files and config the "torrc" can I just launch the tor.exe and then test it's working? - is this the only way to run a relay on Windows? Hoping there's a special approach to simplify the process (now I know why there aren't more of them). Thanks, -Ben Rafael Rodriguez rafaelr at icctek.com Wed Nov 5 00:47:46 UTC 2014 Previous message: [tor-relays] Windows Tor Server Guide Next message: [tor-relays] Windows Tor Server Guide Messages sorted by: [ date ] [ thread ] [ subject ] [ author ] Hi, here is it. Please, feel free to contribute to it. RUNNING A TOR SERVER IN WINDOWS - Download latest Tor Browser Bundle. - Install to c:tor - Create a temporary folder on your Desktop and name it "server". - Copy all files from C:TorBrowserTorBrowserDataTor to the "server" folder on the Desktop. - Browse to C:TorBrowserTorBrowserTor; delete the folder "PluggableTransports" and it content. - Copy all files from C:TorBrowserTorBrowserTor to the "server" folder on the Desktop. - Browse to C:Tor and delete everything inside that folder. C:Tor should be completely empty at this point. - Move all files from the "server" folder on your Desktop to C:Tor - Browse to C:Tor and create a new folder named "datadir". - Create a new text file in C:Tor named "notices" (I myself use notices.log but we want to keep it simple for users who may not know how to change the file extension from .txt to .log) - EDIT C:TORTORRC FILE: (this could be the torrc-defaults file and all its comments). Note that the sample below is just for references. Each user needs to define her/his own parameters based on their own needs and that's impossible for me to cover in a single file for everyone. Hence, each parameter should be included in the torrc-defaults with due comments to be used as reference. Also, noted that I'm using IPv4 geoip by default. Users using IPv6 should define geoip6 in their torrc file. Then again, I cannot use a single sample file for all deployments. The defaults file should be used as reference once again. DATADIRECTORY .DATADIR LOG NOTICE FILE .NOTICES.TXT GEOIPFILE .GEOIP AvoidDiskWrites 1 SocksPort 0 ORPort 9001 DirPort 9030 ExitPolicy reject *:* Nickname RelayBandwidthRate RelayBandwidthBurst Up until this point, all I've written is nothing more than using the default Tor Bundle to create a "Server" package. All steps above could be made easier for users if a "Tor Windows Server" package was available for download on the Tor Project or somewhere else. I refuse the idea of creating such package myself to distribute it since many packages could start floating on the net and bad intentioned people could bundle them with arbitrary code, viruses and so on. A Windows Installer package can be built for distribution though. Next, I will address the two main things we need to run tor as a Windows service (server): 1- Install Tor as Windows Service. 2- Security (Isolating the Tor service). INSTALL TOR AS WINDOWS SERVICE I personally use nssm [2] (Non-Sucking Service Manager) myself to register the service but feel free to use default Windows tools for registering Tor service if you believe so. Anyways, irrespective the tool used to register the Tor service, we just need the following: Service: C:Tortor.exe Name: TorServer Parameters: -f C:Tortorrc Start the TorServer service and everything should just work at this point. The datadir directory will be populated with tor files once started and the notices.txt file will also reflect so. SECURITY (Quick explanation - We can go into details later) - Create a Standard user account and name it Tor with a strong password. - Policies: 1- Deny access to this computer from the network 2- Deny log on locally 3- Deny log on through Remote Desktop Services - NTFS Permissions for Tor windows user account: 1- Read/Write permissions to datadir folder 2- Read/Write permissions to notices.txt or (notices.log) file - Open Services, Start -> Run -> type "services.msc" without quotes, press enter and your Services window will pop up. Scroll down and find the TorServer service and double click it. Move to the LOG ON tab and set the "Log on as: This account: .TOR. Enter the strong password for the Tor user account in the password field and apply changes. Restart the service and now Tor will be running in its own isolated/limited account in Windows.
