Re: [tor-relays] Speed up of reconnections after IP Address change

'tor service start' disconnects all connections, START uses the new IP address. Which is important. I am not sure if Sighup does the same. I assume it only reloads the config file. Any ideas?

Hi ThereI've just written a simple bash script which verifies (in a while loop) every 2 minutes if the OR address has been changed by my ISP. If so, it stops and then restarts the Tor service again. Then it sleeps for 24 hours and starts the 2 minute loop again. Not very sophisticated, but it might work. Mike

how to generate relay keys manually (before actually running the relay)

In these folders you will then find the fingerprint that you can use in MyFamily, so you don't have to touch your existing relays anymore once you actually use these generated keys on new relays. Make sure you take care of filesystem permissions when using these keys on the actual relay.

Container tor relay

Had a search but cant find much info on running tor relays in containers specifically by proxmox lxc containers - I have a free server atm but dont really want to spinup a load of vms when I could do containers instead - its a load test for me but would mean quite a few relays running with gbps network card (all their own ip's) Anyone tried this yet?

Speed up of reconnections after IP Address change
by balbea16 03 Jan '17

03 Jan '17

Hi There,I only have a dynamic IP address and my ISP changes it almost every time after 24 hours. It is somehow sad to see 1.400 connections drop to almost none. After the change it takes 20 minutes until my OR notices this (our IP Address has changed from ...). It than takes another hour until the connections start to actualy rebuild. This means it takes more than an hour (every per day) to reach the normal operating Mode. Is there any way to speed up this process? Could adjust the torrc script for instance? TNX Mike

Re: [tor-relays] Unwarranted discrimination of relays with dynamic IP
by balbea16 03 Jan '17

03 Jan '17

Hi There I evaluated some relays with newly assigned (red) guard flags. All of them had already the stable flag assigned. And (so far I could see) all of them had (almost) static IP addresses. In my case, this may be the reason why I don't get a guard flag. My ISP changes it every 24 hours. However, I'd be fine with "just" operating a fast middle node. I will keep an eye on this. Mike

Grizzly Steppe
by Dr Gerard Bulger 02 Jan '17

02 Jan '17

I ran an exit node, but gave up after too many abuse reports that annoyed my ISP. So I turned al exit ports off, and reports stopped as a rely. After months and many terabytes of data I get an abuse complaint that my tor IP has been used for espionage. "NCSC have been made aware of a report and associated malicious indicators released by the United States Government relating to malicious cyber activity. A copy if the report and indicators can be found at the following link:- https://www.us-cert.gov/security-publications/GRIZZLY-STEPPE-Russian-Malicio us-Cyber-Activity Details within this report indicate network assets which may have been compromised or associated with malicious activity. We have identified the following IP address from this report as x.x.x.x As a minimum, it is recommended that you check systems and any available logs concerned with the above addresses for indications of malicious activity" There are no other details as to HOW my tor relay is being used. The espionage seems to relay on the stupidity of recipients on receiving emails asking for passwords. I am not sure HOW ISP or relay service can stop that. Or is it that my relay was being used to transfer the data? I assume my IP was found by way of a DNS leak which I need to look into. There is nothing else I can do as a relay to stop this or is there? Gerry

How can we trust the guards?
by Rana 01 Jan '17

01 Jan '17

Sorry for the naïve question, but we have a total of about 7000 relays, many of them residential and thus practically unused or very lightly used. So the actual number of relays that carry most of the traffic is rather small, and many of them are middle relays, leaving an even smaller number of guard relays. This means that an adversary with a rather modest budget can easily take over half the guards. Whats the trust mechanism (if any) to ensure that the majority of guards are not hijacked by adversaries?

Is this something that could > be implemented effectively with the dreaded web of trust? Yes. It has been repeatedly brought up among tor that relay operators, being globally spread and relatively physically mobile for the purpose of keysigning, can cross sign their node keys with gpg keys, have their gpg keys signed in person under proof of relay ownership as usual, dump the fingerprints into the consensus and sks, then build relay selection algorithms that download and verify the wot into user run tools that then build their circuits in the controller. Users can elect to use variant levels of trust present in the wot, anon / nym / context signing, ID signing, photo signing, multisig assertions, etc. Beyond just the wot, all sorts of other external metrics, even subscriptions to third party metrics services, could be applied to such a relay selection process. 7000 relays, even at low 10% shill and 1:1 would require 700 unique persons of the adversary that pass the smell test of other operators and principals, that has real costs. Or your allies just supply the number of validated nodes needed to prevent network saturation and users simply decline to route anything but CNN and gerbil pr0n through the 700 unvalidated nodes. Pretty simple really, needs nothing more than one structured comment field in the consensus and some external tools, but nobody has rolled it out or even developed concept further yet.

"Graceful" Restart of Tor-Relay ?
by mistral.relay＠posteo.net 30 Dec '16

30 Dec '16

Hello all, a newbie question: assuming that I want to shut down and restart a running tor-relay (for whatever reason; e.g. a linux reboot is required) - is it fine to just shut down the relay or is there a nicer, more tor-user friendly way so circuits don't drop for them unexpectedly? I was thinking about a command to tell tor to complete whatever is ongoing, but to not accept any new circuits or other requests and then stop working. Would setting the BandwidthBurst to 0 followed by a tor-reload do this over some time (checking with e.g. arm what is still ongoing)? Many thanks!

TransPort: Convert iptables to pf
by diffusae 28 Dec '16

Hello! Does anybody know how to convert this to pf rules in FreeBSD: iptables -t nat -A OUTPUT -p tcp -d 10.192.0.0/10 -j REDIRECT --to-ports 9040 I' running a Tor client in a jail on a different IP and want to route only the .onion traffic through. The DNS stuff is working fine, but I can't find a solution for the above iptables rule, which is working. I like transparently do DNS and Routing for .onion traffic on the network. I looked into the wiki and also find some pf rules, which are routing all the traffic though Tor, but this only works locally. The machine is on FreeBSD 11.0-STABLE. Tor is running in a jail with cloned loopback interface (lo1) and has also a private IP address on the main NIC. Maybe you have some hints. Thanks a lot Regards,

Relay is missing Running flag in the consensus
by Dmitrii Tcvetkov 28 Dec '16

28 Dec '16

Hello, I have a problem with one[1] of my exit relays: about a week ago this relay lost its Running flag, but it was running all the time. I upgraded Tor on this relay to 0.2.9.7-rc from "tor-devel" FreeBSD port and restarted it. Relay was and still is accessible from outside via ports 80 and 443. FreeBSD version is 11.0-RELEASE-p2. After about 24 hours running on new version I decided to check votes from bwauth on detailed page here[2]. Back then the relay had votes for Running flag from maatuuska, dizum and dannenberg. I've checked the relay's ability to open connections to bwauths and it couldn't connect to longclaw - connection timed out, all other bwauths are reachable from the relay. Test was performed by command "openssl s_client -connect <bwauth ip>:443". Ipfw and pf are disabled on the server, there are only tor, ssh and local_unbound running, unbound uses my recursive DNS resolver on another server. DNS queries are resolved fine. Then I saved /var/db/tor directory and started Tor with fresh identity[3], but in about 6 hours it showed similiar symptoms: only maatuska, dizum and dannenberg were voting for it, so I switched back to old identity[1] since. In December 23th I decided to downgrade Tor version back to 0.2.8 from FreeBSD port "tor" and I enabled info level logging. The relay was running since with version 0.2.8.11, at the moment still only 3 bwauth are voting "Running" flag for it: maatuska, dizum and dannenberg. All bwauths except longclaw are accessible from the server. All bwauths are accessible from my neighbour relays in the same datacenter[4][5]. Log info.log has size of 200 megabytes at the moment, first concerning message is: Dec 23 11:54:23.000 [warn] Cannot make an outgoing connection without a DirPort. messages during relay startup, but they disappear eventually: # grep -c 'outgoing connection without a DirPort' info.log 19 They don't look like a reason for the problem. Another anomaly is huge amount of messages like Dec 23 11:54:24.000 [info] router_pick_published_address: Success: chose address '85.143.213.44'. ... Dec 26 13:58:31.000 [info] router_pick_published_address: Success: chose address '85.143.213.44'. # grep -c router_pick_published_address info.log 1653449 I upgraded Tor to version 0.2.9.8 from FreeBSD port "tor". The flood of router_pick_published_address doesn't reproduce with new version. I can compress the log file to 2 mb file with xz -9 and publish it, though I don't want to do it right away because of the warning: Dec 23 11:54:20.000 [warn] Your log may contain sensitive information - you're logging more than "notice". Don't l og unless it serves an important reason. Overwrite the log afterwards. as I don't really know what exact info I should scrub from it. Currently relay is running with identity[1] and version 0.2.9.8 with info logging.
