This can overwhelm consumer-level routers. If you run the Tor +relay from a server (virtual or dedicated) in a data center you will be fine. +If you run it behind a consumer-level router at home you will have to try and +see if your home router can handle it or if it starts failing. Fast exit +relays (>=100 Mbit/s) usually have to handle a lot more concurrent connections +(>100k). + +It is recommended that a relay have at least 16 Mbit/s (Mbps) upload bandwidth +and 16 Mbit/s (Mbps) download bandwidth available for Tor. More is better. The +minimum requirements for a relay are 10 Mbit/s (Mbps). If you have less than 10 +Mbit/s but at least 1 Mbit/s we recommend you run a [bridge with obfs4 +support](https://trac.torproject.org/projects/tor/wiki/doc/PluggableTransports/obfs4proxy). +If you do not know your bandwidth you can use http://beta.speedtest.net to +measure it. + +# Monthly Outbound Traffic + +It is required that a Tor relay be allowed to use a minimum of 100 GByte of +outbound traffic (and the same amount of incoming traffic) per month. Note: That +is only about 1 day worth of traffic on a 10 Mbit/s (Mbps) connection. More (>2 +TB/month) is better and recommended. **Ideally a relay runs on an unmetered plan** +or includes 20 TB/month or more. If you have a metered plan you might want to +configure tor to only use a given amount of [bandwidth or monthly traffic](FIXME). + +# Public IPv4 Address + +Every relay needs a public IPv4 address - either directly on the host +(preferred) or via NAT and port forwarding. + +The IPv4 address is not required to be static but static IP addresses are +preferred. Your IPv4 address should remain unchanged for at least 3 hours (if it +regularly changes more often than that, it does not make much sense to run a +relay or bridge there since it takes time to distribute the new list of relay +IPs to clients - which happens only once every hour). + +Additional IPv6 connectivity is great and recommended/encouraged but not a +requirement. There should be no problem at all with this requirement (all +commercially available servers come with at least one IPv4 address). + +Note: You can only run two Tor relays per public IPv4 address. If you want to +run more than two relays you will need more IPv4 addresses. + +# Memory Requirements + +* A <40 Mbit/s non-exit relay should have at least 512 MB of RAM available. +* A non-exit relay faster than 40 Mbit/s should have at least 1 GB of RAM. +* On an exit relay we recommend at least 1.5 GB of RAM per tor instance. + +# Disk Storage + +Tor does not need much disk storage.

Having full control over the hardware and connection gives you a +more controllable and (if done correctly) secure environment. You can host your +own physical hardware at home (do NOT run a Tor exit relay from your home) or in +a data center. Sometimes this is referred to as installing the relay on "bare +metal". + +If you do not own physical hardware, you could run a relay on a rented dedicated +server or virtual private server (VPS). This can cost anywhere between +$3.00/month and thousands per month, depending on your provider, hardware +configuration, and bandwidth usage. Many VPS providers will not allow you to run +exit relays. You must follow the VPS provider's terms of service, or risk having +your account disabled. For more information on hosting providers and their +policies on allowing Tor relays, please see this list maintained by the Tor +community: [GoodBadISPs](FIXME). + +## Questions to consider when choosing a hoster + +* How much monthly traffic is included? (Is bandwidth "unmetered"?) +* Does the hoster provide IPv6 connectivity? (it is recommended, but not required) +* What virtualization / hypervisor (if any) does the provider use?

(explicitly ask them before starting an +exit relay there) +* Does the hoster allow custom WHOIS records for your IP addresses?

(DNS PTR record) +This are probably things you will need to ask the hoster in a Pre-Sales ticket + +# AS/location diversity + +When selecting your hosting provider, consider network diversity on an +autonomous system (AS) and country level. A more diverse network is more +resilient to attacks and outages. Sometimes it is not clear which AS you are +buying from in case of resellers. To be sure it is best to ask the hoster about +the AS number before ordering a server. + +It is best to avoid hosters where many Tor relays are already hosted, but it is +still better to add one there than to run no relay at all. **Try to avoid** the +following hoster: + +* OVH SAS (AS16276) +* Online S.a.s. (AS12876) +* Hetzner Online GmbH (AS24940) +* DigitalOcean, LLC (AS14061) + +To find out which hoster and countries are already used by many other operators +(that should be avoided) you can use Relay Search: + +* [Autonomous System Level +Overview](https://metrics.torproject.org/rs.html#aggregate/as) +* [Country Level Overview](https://metrics.torproject.org/rs.html#aggregate/cc) + +# Choosing an Operating System + +We recommend you use the operating system you are most familiar with. Please +keep in mind that since most relays run on Debian and we want to avoid a +monoculture, BSD and other non-Linux based relays are greatly needed. + +The following table shows the current OS distribution on the Tor network to give +you an idea of how much more non-Linux relays we should have: + +* https://nusenu.github.io/OrNetStats/#os-distribution-relays + +# OS Level Configuration + +OS configuration is outside the scope of this guide but the following points are +crucial for a Tor relay, so we want to mention them here nonetheless. + +## Time Synchronization (NTP) + +Correct time settings are essential for Tor relays. It is recommended that you +use the network time protocol (NTP) for time synchronization and ensure your +timezone is set correctly. + +## Automatic Software Updates + +One of the most imported things to keeps your relay secure is to install +security updates timely and ideally automatically so you can not forget about +it. We collected the steps to enable automatic software updates for different +operating systems: + +* [RPM-based distributions](FIXME) (RHEL, CentOS, Fedora, openSUSE) +* [Debian/Ubuntu](FIXME) +* [FreeBSD/HardenedBSD](FIXME) + +# Tor Relay Setup: Installation and Configuration + +This section covers the installation and configuration of the program required +to run a Tor relay for various operating systems. These steps are intended for +the latest stable version of the given OS, on Ubuntu for the latest LTS release. + +Note: For some operating systems, there are alpha version packages available +(tor versions with new features not deemed to be stable yet). These are only +recommended for people eager to test and report bugs in bleeding edge +releases/features. If you are looking to run a relay with minimal effort we +recommend you stick to stable releases. + +In this guide we describe how to setup a new non-exit relay. By reading further +you can easily switch to become an exit relay. + +**Questions you should clarify before configuring Tor:** + +* Do you want to run a Tor exit or non-exit (guard/middle) relay? +* If you want to run an exit relay: Which ports do you want to allow in your +exit policy? (more ports usually means potentially more abuse complains) +* What external TCP port do you want to use for incoming Tor connections? +("ORPort" configuration, we recommend port 443 if that is not used by another +daemon on your server already. ORPort 443 is recommended because it is often one +of the few open ports on public WIFI networks. Port 9001 is another commonly used ORPort.) +* What email address will you use in the ContactInfo field of your relay(s)? +Note: This information will be made public. +* How much bandwidth/monthly traffic do you want to allow for Tor traffic? +* Does the server have an IPv6 address? + +The installation commands are shown in code blocks and must be executed with root privileges. + +## 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). + +## Configuration Management + +Tor does not scale well on multi-core machines. If you run a Tor relay on a +server with a fast Internet uplink (>200 Mbit/s) you might want to consider +running multiple Tor instances on a single server with multiple cores. Note: You +can only run two tor instances per public IPv4 address. + +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/OfflineKeys) +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: + +http://github.com/nusenu/ansible-relayor + +## Platform specific Instructions + +Please choose your platform: + +* Debian/Ubuntu +* CentOS/RHEL +* Fedora +* FreeBSD +* openSUSE + +## 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. + +# Getting Help + +If you run into problems while setting up your relay you can ask your questions +on the public tor-relays mailing list: + +* https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-relays + +This is a great resource for asking (and answering) questions, and generally +getting to know other relay operators. Make sure to check out the archives! + +# 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 + +# IPv6 + +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. + +he 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. + +# 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 don't +use them in multiple position 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 relaygroups is error prone and can put Tor clients at risk. + +# Exit Relay Configuration + +It is recommended that you setup exit relays on servers dedicated to this +purpose. It is not recommended to install Tor exit relays on servers that you +need for other services as well. Do not mix your own traffic with your exit +relay traffic. + +## Reverse DNS and WHOIS record + +Before switching your relay to become an exit relay, ensure that you have set a +clear DNS reverse (PTR) record to make it clear for everyone that this is a tor +exit relay. Something like "tor-exit" it its name is a good start. + +If your provider offers it, make sure your WHOIS record contains clear +indications that this is a Tor exit relay. + +## Exit Notice HTML page + +To make it even more obvious that this is a Tor exit relay you should serve a +Tor exit notice HTML page. Tor can do that for you if your DirPort is on TCP +port 80, you can make use of tor's DirPortFrontPage feature to display a +HTML file on that port. This file will be shown to anyone directing his browser +to your Tor exit relay IP address. + +``` +DirPort 80 +DirPortFrontPage /path/to/html/file +``` + +We offer a sample Tor exit notice HTML file, but you might want to adjust it to +your needs: +https://gitweb.torproject.org/tor.git/plain/contrib/operator-tools/tor-exit-notice.html + +Here are some more tips for running a reliable exit relay: +https://blog.torproject.org/tips-running-exit-node + +## Exit Policy + +Defining the [exit +policy](https://www.torproject.org/docs/tor-manual.html.en#ExitPolicy) +is one of the most important parts of an exit relay configuration. The exit +policy defines which destination ports you are willing to forward. This has an +impact on the amount of abuse emails you will get (less ports means less abuse +emails, but an exit relay allowing only few ports is also less useful). If you +want to be a useful exit relay you must **at least allow destination ports 80 +and 443**. + +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/ReducedExitPolicy) +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.

Several countries, including +China and Iran, have found ways to detect and block connections to Tor bridges. +Pluggable transports +(https://www.torproject.org/docs/pluggable-transports.html.en), a special +kind of bridge, address this by adding an additional layer of obfuscation. + +Bridges are relatively easy, low-risk and low bandwidth Tor nodes to operate, +but they have a big impact on users.
