IP and SWIP for a Tor exit node

>What are additional IPs good for? My ISP sells additional >(public) IPs for 3,60 euro/month, would it be worth it or >necessary purchasing such an additional service? For the size node presently indicated, additional IP address are of no particular value. Extra IPs can be use for 1) running additional 'tor' router instances on medium-to-large multi-core servers with high available bandwidth (high as in 100TB/month per core for non-AES-NI CPU cores, multiple 1G connections or a 10G network connection for AES-NI CPUs) 2) allowing exit traffic to travel out on different interfaces than the OR port--not sure if that provides extra value 3) perhaps running a bridge node instance along with the router instance--is best to have non-adjacent IPs 4) for bridge-only setups extra IPs allow one to start new bridge instances when old ones are blocked by censors and/or simply run multiple bridges; again non-contiguous addresses are best If you can obtain a "bare-metal," "root" or "dedicated" server (synonyms) for a good price, in general the router will be dramatically faster due to better latency afforded by the lack of a virtualization layer and lack of competition from other users. Similar for Linux container setups where virtualization is almost free, but servers can be heavily loaded with numerous customers.

Blutmagie is Good Looking and VERY SLOW -- this script is VERY FAST

one more enhancement: added a -W option to have underscore characters used for inactive flag positions. Produces a single column for flags, thus enabling trivial command-line 'awk' and 'perl -n' scripting.

new exit node
by support＠ruggedinbox.com 26 Sep '15

26 Sep '15

Hi we are running from few hours a new Tor exit node: 87.120.37.163 aka tor-exit-node-01.cryptonoid.com aka cryptonoid.com We couldn't register the IP with ARIN but of course the data center knows what we are doing and is willing to take the risk, we hope to be able to handle the abuses notices and are here to learn :) The current configuration is: ORPort 9001 Address tor-exit-node-01.cryptonoid.com Nickname cryptonoid01 RelayBandwidthRate 768 KB RelayBandwidthBurst 1024 KB ContactInfo RuggedInbox team <support(a)ruggedinbox.com> DirPort 9030 DirPortFrontPage /etc/tor/tor-exit-notice.html ExitPolicy accept *:22 ExitPolicy accept *:80 ExitPolicy accept *:443 ExitPolicy accept *:465 ExitPolicy accept *:993 ExitPolicy accept *:995 ExitPolicy reject *:* Does it looks good to you ? Currently both https://torstatus.blutmagie.de and https://atlas.torproject.org/#search/87.120.37.163 show the server as 'relay', not as exit. Is that normal ? Thank you, RuggedInbox team

Legal status of operating Tor exit in UK?
by Jonathan Baker-Bates 23 Sep '15

23 Sep '15

I run an exit node with an ISP who initially indicated they would not have a problem with Tor as long as I was transparent about what I was doing, and ran a sufficiently reduced exit policy. They have now sent me evidence of malicious traffic coming from the exit. I don't think they've had any 3rd party complaints about this traffic, but they have expressed various misgivings about Tor in general. They now also want me to consider running Snort IDS on the outgoing traffic. I don't intend to monitor my traffic. But it occurs to me I don't know whether my ISP needs to be worried about it or not. The last one wasn't, so why them? I've asked the EFF about the legal situation in the UK, who passed me to the Open Rights Group. They've not replied to my enquiry as of three weeks ago. So does anyone know of any reliable source of information on running Tor exits in the UK? What would happen if my ISP pressed me to monitor my traffic, and I refused on legal grounds? I'm not suggesting I actually do that, or that there are even any legal grounds to refuse. In fact right now I'm resigned to closing down the node if my ISP turns up the heat. They probably have me by the balls. But I'm at least curious, and can't immediately find any information about things like public carrier status, or traffic monitoring conducted by people like me when it's done in the context of onion routing. Thanks in advance for any help.

Re: [tor-relays] Deciding where to put new Tor relays

After talking with APNIC/RIPE, it looks like that if we ask nicely we can get high-quality BGP-peering graphs for the entire Internet (not 100% complete, but it's the same data they use internally). Spend some time thinking about exactly what kinds of attacks we wish to harden against. Once we understand the attacks, I'll figure out the appropriate graph-theory for hardening against it. -V On Mon, Sep 21, 2015 at 6:48 PM Moritz Bartl <moritz(a)torservers.net> wrote: > Interesting, thanks for the update.

Tor is starting without the -f /etc/tor/torrc option
by Tor Stuff 22 Sep '15

22 Sep '15

I am running tor on a new Ubuntu 14.04.3 LTS system. I have restarted tor a couple of times with service tor restart I noticed when I start arm that it is telling me that The torrc differs from what tor's using. You can issue sighup to reload ... It seems that tor is running with default values and is not reading /etc/tor/torrc as there is no ... -f /etc/tor/torrc option being used by the running tor when it is displayed with 'ps'. The 'ps' output for the tor instance is /usr/bin/tor --defaults-torrc /usr/share/tor/tor-service-defaults-torrc --hush I had asumed that because I have set DirPort to 80 and ORPort to 443 in /etc/tor/torrc and can see in the tor log files that those two ports are reachable from outside, that the running tor was reading /etc/tot/torrc. Something is amiss with my tor configuration but I don't know what. Any hints as to where to look would be welcome while I try to RTFM again! Cheers Q

Non-standard Bridge
by Geoff Down 21 Sep '15

21 Sep '15

Hello all, I'm trying to set up a Bridge/Client Tor instance with the following torrc: ControlPort 9051 ExitPolicy reject *:* HashedControlPassword <pwd> Nickname <nickname> ORListenAddress 0.0.0.0:9001 ORPort 80 BridgeRelay 1 ContactInfo <contactinfo> Should this work as a bridge? Client functionality is fine (port 80 is forwarded to 9001) but there is no reachability test in the log. I have a "bridge's hashed identity key fingerprint" in there; where is it I can check online to be sure the BridgeDB has received it? I wanted to check it worked with fixed ports before I tried 'ORPort auto'. GD -- http://www.fastmail.com - Faster than the air-speed velocity of an unladen european swallow

The default one makes sure e.g. privilege dropping to user debian-tor and a few other things in case you miss to set them properly. My ORPort and other config is done via my torrc. And I would bet a cup of tasty coffee that Tor on Ubuntu looks for /etc/torrc and not for /etc/tor/torrc, but I always lose when I'm willing to bet, so I guess it's just a little stubborn.

Why are Globe/Atlas not showing my upgraded (& advertised) bandwidth
by Tor Stuff 20 Sep '15

20 Sep '15

It is now more 7 hours since I restarted my Middle Relay after the upgrade to my broadband to FTTC which by various tests is consistently showing more than 75/20 Mbits/s speeds now. I edited my torrc file and set RelayBandwidthRate and RelayBandwidthBurst to 2.5 MBytes to reflect my new fast connection. The Tor log shows that both the DirPort and ORPort are reachable from the outside since the restart. Arm is correctly showing my bandwidth (limit & burst) as 20 Mb/s. However both Globe and Atlas are showing an Advertised Bandwidth which is less than my previous RelayBandwidthRate and RelayBandwidthBurst settings of 100 KBytes and 110 KBytes respectively! I have been running this node (nickname 'Geheimschreiber') with fingerprint C69D24F9353E16D85E82B4A9E4571DFAF6DCF531 for many months so expected Atlas/Globe to pickup my changed capabilities fairly quickly. Am I being too impatient or have I omitted something in my Tor configuration? Thanks Q
