Please let us know by sending email to bad-relays AT lists DOT torproject DOT org! Many bad relays are caught thanks to our wider community, so many thanks for all your help and vigilance! + +### What is a bad relay? + +A bad relay is one that either doesn't work properly or tampers with our users' connections. This can be either through maliciousness or misconfiguration. Some common examples are... + + * Tampering with exit traffic in any way (including dropping accepted connections). This might be accidental (such as an anti-virus filter) or malicious (commonly SSLStrip, which replaces https:// links with http:// to snoop on traffic) or even intentional (such as layer 7 inspection for P2P traffic detection/mitigation). + * Running HSDirs that harvest and probe .onion addresses + * Manipulating the DHT that is used for onion services, e.g., by positioning itself in the DHT. + * Using a DNS provider that censors its results (such as some [OpenDNS](http://www.opendns.com) or Quad (9 9.9.9.9) configurations). + * Performing a [Sybil attack](https://en.wikipedia.org/wiki/Sybil_attack), which means flooding the network with new relays in an effort to deanonymize users. If you want to run multiple relays then that's great! But please be sure to set the [MyFamily parameter](https://www.torproject.org/docs/tor-manual.html.en#MyFamily). + * Exit relays routing their exit traffic back into the tor network (not actually exiting any traffic) + +Also, if your relay is stolen or goes missing, please report it as well, so we can blacklist it in case whoever took it puts it back online. + +The following are currently permitted yet do have some discussion for prohibition (as such, they should not be reported at this time)... + + * Only allowing plain-text traffic (for instance, just port 80). There's no good reason to disallow its encrypted counterpart (like port 443), making these relays highly suspect for sniffing traffic. See [context](https://www.google.com/search?site:torproject.org+80+443+6667) and [spec](https://gitweb.torproject.org/torspec.git/tree/dir-spec.txt#n1969). + +### How do I report a bad relay? + +If you encounter a bad relay then please let us know and write to `bad-relays AT lists DOT torproject DOT org`. + +You can check which exit you are using at any time by visiting [tor check](https://check.torproject.org/). Please include the following in your report: + + 1. The relay's IP address or fingerprint. The fingerprint is a forty-character hex string such as `203933ED4E55EF8A3C3518427D1A1ED6A4CC285E`. + 2. What kind of behavior did you see? + 3. Any additional information we'll need to reproduce the issue. + +However, if you need help with anything Tor-related, please contact the [help desk](https://www.torproject.org/about/contact) instead. + +### What happens to bad relays? + +After a relay is reported and we've verified the behavior we'll attempt to contact the relay operator. Often we can sort things out but if not (or the relay lacks contact information) we'll flag it to prevent it from continuing to be used. + +We have thee types of flags we can apply: + + * BadExit - Never used as an exit relay (for relays that appear to mess with exit traffic) + * Invalid - Never used unless AllowInvalidNodes is set (by default this only allows for middle and rendezvous usage) + * Reject - Dropped from the consensus entirely + +Which we use depends on the severity of the issue, and if it can still be safely used in certain situations. + +### My relays was given the BadExit flag. What's up? + +In just about all cases we're unable to contact the operator to resolve the issue, so if your relay has been flagged as a BadExit then please let us know (see above for contact info) so we can work together to fix the issue. + +### Do you actively look for bad relays? + +Yes. For our automated issue detection see [exitmap](http://www.cs.kau.se/philwint/spoiled_onions/) and [sybilhunter](https://gitweb.torproject.org/user/phw/sybilhunter.git/). + +Other monitors include [tortunnel](http://www.thoughtcrime.org/software/tortunnel/), [SoaT](https://gitweb.torproject.org/torflow.git/blob/HEAD:/NetworkScanners/…, [torscanner](https://code.google.com/p/torscanner/), and [DetecTor](http://detector.io/DetecTor.html). + + +--- +html: two-columns-page.html +--- +key: 7 +--- +section: Community Resources +--- +section_id: bad-relays +--- +subtitle: Learn how to report relays that either doesn't work properly or tampers with our users' connections

Note that it can take several days or weeks until you see a consistent set of users, so don't get discouraged if you don't see user connections right away. BridgeDB uses four buckets for bridge distribution: HTTPS, Moat, Email, and manual. Some buckets are used more than others, which also affects the time until your bridge sees users. Finally, there aren't many bridge users out there, so you cannot expect your bridge to be as popular as a relay. If you want to connect to your bridge manually, you will need to know the bridge's obfs4 certificate.

-As a new exit relay - especially if you are new to your hoster - it is good to start with a reduced exit policy (to reduce the amount of abuse emails) and further open it up as you become more experienced. -The reduced exit policy can be found on the [ReducedExitPolicy](https://trac.torproject.org/projects/tor/wiki/doc/Reduce… wiki page. - -To become an exit relay change ExitRelay from 0 to 1 in your torrc configuration file and restart the tor daemon. - -``` -ExitRelay 1 -``` - -## DNS on Exit Relays - -Unlike other types of relays, exit relays also do DNS resolution for Tor clients. -DNS resolution on exit relays is crucial for Tor clients, it should be reliable and fast by using caching. - -* DNS resolution can have a significant impact on the performance and reliability your exit relay provides. - Poor DNS performance will result in less traffic going through your exit relay. -* Don't use any of the big DNS resolvers as your primary or fallback DNS resolver to avoid centralization (Google, OpenDNS, Quad9, Cloudflare, 4.2.2.1-6) -* We recommend running a local caching and DNSSEC-validating resolver without using any forwarders (specific instructions follow bellow for each operating systems) -* if you want to add a second DNS resolver as a fallback to your /etc/resolv.conf configuration, try to choose a resolver within your autonomous system and make sure it is not your first entry in that file (the first entry should be your local resolver) -* if a local resolver like unbound is not an option for you try to use a resolver that your provider runs in the same autonomous system (to find out if an IP address is in the same AS as your relay, you can look it up, using for example https://bgp.he.net). -* try to avoid adding too many resolvers to your /etc/resolv.conf file to limit exposure on an AS-level (try to not use more than two entries) - -There are multiple options for DNS server software, unbound has become a popular one but **feel free to use any other you are comfortable with**. -When choosing your DNS resolver software try to ensure it supports DNSSEC validation and QNAME minimisation (RFC7816). -In every case the software should be installed using the OS package manager to ensure it is updated with the rest of the system. - -By using your own DNS resolver you are less vulnerable to DNS-based censorship that your upstream resolver might impose. - -Here follow specific instructions on how to install and configure unbound on your exit - a DNSSEC-validating and caching resolver. unbound has many configuration and tuning nobs but we try to keep these instructions as simple and short as possible and the basic setup will do just fine for most operators. - -After switching to unbound verify it works as expected by resolving a valid hostname, if it does not work, you can restore the old resolv.conf file. - -### Debian/Ubuntu - -The following 3 commands install unbound, backup your DNS configuration and tell the system to use the local unbound: - -``` -apt install unbound -cp /etc/resolv.conf /etc/resolv.conf.backup -echo nameserver 127.0.0.1 > /etc/resolv.conf -``` - -To avoid that the configuration gets changed (for example by the DHCP client): - -``` -chattr +i /etc/resolv.conf -``` - -The Debian configuration ships with QNAME minimisation (RFC7816) enabled by default so you don't need to enable it explicitly. -The unbound resolver you just installed does also DNSSEC validation. - -### CentOS/RHEL - -Install the unbound package: - -``` -yum install unbound -``` - -in /etc/unbound/unbound.conf replace the line - -``` -# qname-minimisation: no -``` - -with: - -``` -qname-minimisation: yes -``` -

-To avoid that the configuration gets changed (for example by the DHCP client): - -``` -chattr +i /etc/resolv.conf -``` - -### FreeBSD - -FreeBSD ships unbound in the base system but the one in ports is usually following upstream more closely so we install the unbound package: -

Make sure relay ports can be reached - -If you are using a firewall, open a hole in your firewall so incoming connections can reach the ports you will use for your relay (ORPort, plus DirPort if you enabled it). - -Also, make sure you allow all outgoing connections too, so your relay can reach the other Tor relays, clients and destinations. - -You can find the specific ORPort TCP port number in the torrc configuration samples bellow (in the OS specific sections). - -# 2. Verify that your relay works - -If your logfile (syslog) contains the following entry after starting your tor daemon your relay should be up and running as expected: - -``` -Self-testing indicates your ORPort is reachable from the outside. Excellent. -Publishing server descriptor. -``` - -About 3 hours after you started your relay it should appear on [Relay Search](https://metrics.torproject.org/rs.html). -You can search for your relay using your nickname or IP address. - -# 3. Read about Tor relay lifecycle - -It takes some time for relay traffic to ramp up, this is especially true for guard relays but to a lesser extend also for exit relays. To understand this process, read about the [lifecycle of a new relay](https://blog.torproject.org/lifecycle-new-relay). - -# 4. Configuration Management - -If you plan to run more than a single relay, or you want to run a high capacity relay (multiple Tor instances per server) or want to use strong security features like [Offline Master Keys](https://trac.torproject.org/projects/tor/wiki/doc/TorRelaySecurity/Of… without performing additional steps manually, you may want to use a configuration management for better maintainability. - -There are multiple configuration management solutions for Unix based operating systems (Ansible, Puppet, Salt, ...). - -The following Ansible Role has specifically been build for Tor relay operators and supports multiple operating systems: [Ansible Relayor](http://github.com/nusenu/ansible-relayor). - -# 5. Important: if you run more than one Tor instance - -To avoid putting Tor clients at risk when operating multiple relays you must set a proper [MyFamily](https://2019.www.torproject.org/docs/tor-manual.html.en#MyFamily) value and have a valid [ContactInfo](https://2019.www.torproject.org/docs/tor-manual.html.en#Contac… in your torrc configuration. -The MyFamily setting is simply telling Tor clients what Tor relays are controlled by a single entity/operator/organization, so they are not used in multiple positions in a single circuit. - -If you run two relays and they have fingerprints AAAAAAAAAA and BBBBBBBB, you would add the following configuration to set MyFamily: - -``` -MyFamily AAAAAAAAAA,BBBBBBBB -``` - -to both relays. To find your relays fingerprint you can look into the log files when tor starts up or find the file named "fingerprint" in your tor DataDirectory. - -Instead of doing so manually for big operators we recommend to automate the MyFamily setting via a configuration management solution. -Manually managing MyFamily for big relay groups is error prone and can put Tor clients at risk. - -# 6. Optional: Limiting bandwidth usage (and traffic) - -Tor will not limit its bandwidth usage by default, but supports multiple ways to restrict the used bandwidth and the amount of traffic. -This can be handy if you want to ensure that your Tor relay does not exceed a certain amount of bandwidth or total traffic per day/week/month. -The following torrc configuration options can be used to restrict bandwidth and traffic: - -* AccountingMax -* AccountingRule -* AccountingStart -* BandwidthRate -* BandwidthBurst -* RelayBandwidthRate - -Having a fast relay for some time of the month is preferred over a slow relay for the entire month. - -Also see the bandwidth entry in the [FAQ](https://www.torproject.org/docs/faq.html.en#BandwidthShaping). - -# 7. Check IPv6 availability - -We encourage everyone to enable IPv6 on their relays. This is especially valuable on exit and guard relays. - -Before enabling your tor daemon to use IPv6 in addition to IPv4 you should do some basic IPv6 connectivity tests. - -The following command line will ping the IPv6 addresses of Tor directory authorities from your server: - -``` -ping6 -c2 2001:858:2:2:aabb:0:563b:1526 && ping6 -c2 2620:13:4000:6000::1000:118 && ping6 -c2 2001:67c:289c::9 && ping6 -c2 2001:678:558:1000::244 && ping6 -c2 2607:8500:154::3 && ping6 -c2 2001:638:a000:4140::ffff:189 && echo OK. -``` - -At the end of the output you should see "OK." if that is not the case do not enable IPv6 in your torrc configuration file before IPv6 is indeed working. -If you enable IPv6 without working IPv6 connectivity your entire relay will not be used, regardless if IPv4 is working. - -If it worked fine, make your Tor relay reachable via IPv6 by adding an additional ORPort line to your configuration (example for ORPort 9001): - -``` -ORPort [IPv6-address]:9001 -``` - -The location of that line in the configuration file does not matter you can simply add it next to the first ORPort lins in your torrc file. - -Note: You have to explicitly specify your IPv6 address in square brackets, you can not tell tor to bind to any IPv6 (like you do for IPv4). -If you have a global IPv6 address you should be able to find it in the output of the following command: - -``` -ip addr|grep inet6|grep global -``` - -If you are an exit relay with IPv6 connectivity, tell your tor daemon to allow exiting via IPv6 so clients can reach IPv6 destinations: - -``` -IPv6Exit 1 -``` - -Note: Tor requires IPv4 connectivity, you can not run a Tor relay on IPv6-only. - -# 8. Maintaining a relay - -## Backup Tor Identity Keys - -After your initial installation and start of the tor daemon it is a good idea to make a backup of your relay's long term identity keys. -They are located in the "keys" subfolder of your DataDirectory (simply make a copy of the entire folder and store it in a secure location). -Since relays have a ramp-up time it makes sense to backup the identity key to be able to restore your relay's reputation after a disk failure - otherwise you would have to go through the ramp-up phase again. - -Default locations of the keys folder: - -* Debian/Ubuntu: `/var/lib/tor/keys` -* FreeBSD: `/var/db/tor/keys` - -## Subscribe to the tor-announce mailing list - -This is a very low traffic mailing list and you will get information about new stable tor releases and important security update information: [tor-announce](https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-ann…. - -## Setting up outage notifications - -Once you setup your relay it will likely run without much work from your side. -If something goes wrong it is good to get notified automatically. -We recommend you use one of the free services that allow you to check your relay's ORPorts for reachability and send you an email should they become unreachable for what ever reason. - -[UptimeRobot](https://uptimerobot.com/) is one of these services that allow you to monitor TCP listeners on arbitrary ports. -This service can check your configured ports once every 5 minutes and send you an email should your tor process die or become unreachable. -This checks only for the listener but does not speak the Tor protocol. - -A good way to monitor a relay for its health state is to have a look at its bandwidth graphs. - -## System Health Monitoring - -To ensure your relay is healthy and not overwhelmed it makes sense to have some basic system monitoring in place to keep an eye on the following metrics: - -* Bandwidth -* Established TCP Connections -* Memory -* Swap -* CPU - -There are many tools for monitoring this kind of data, [munin](http://munin-monitoring.org/) is one of them and is relatively easy to setup. - -Note: **Do not make your private monitoring data graphs public since this could help attackers with deanonymizing Tor users.** - -Some practical advice: - -* If you want to publish traffic statistics, you should aggregate all your relays' traffic over at least a week, then round that to the nearest 10 TiB (terabytes). -* Reporting individual relays is worse than reporting totals for groups of relays. In future, tor will securely aggregate bandwidth statistics, so any individual relay bandwidth reporting will be less secure than tor's statistics. -* Smaller periods are worse. -* Numbers are worse than graphs. -* Real-time data is worse than historical data. -* Data in categories (IP version, in/out, etc.) is worse than total data. - -## Tools - - This section lists a few tools that you might find handy as a Tor relay operator. - -* [Nyx](https://nyx.torproject.org/): is a Tor Project tool (formerly arm) that allows you to see real time data of your relay. - -* vnstat: vnstat is a command-line tool that shows the amount of data going through your network connection. -You can also use it to generate PNG pictures showing traffic graphs.
