You'll need to do ipchains or other port forwarding ## yourself to make this work. #ORPort 443 NoListen #ORPort 127.0.0.1:9090 NoAdvertise ## If you want to listen on IPv6 your numeric address must be explictly ## between square brackets as follows. You must also listen on IPv4. #ORPort [2001:DB8::1]:9050 ## The IP address or full DNS name for incoming connections to your ## relay. Leave commented out and Tor will guess. #Address noname.example.com ## If you have multiple network interfaces, you can specify one for ## outgoing traffic to use. ## OutboundBindAddressExit will be used for all exit traffic, while ## OutboundBindAddressOR will be used for all OR and Dir connections ## (DNS connections ignore OutboundBindAddress). ## If you do not wish to differentiate, use OutboundBindAddress to ## specify the same address for both in a single line. #OutboundBindAddressExit 10.0.0.4 #OutboundBindAddressOR 10.0.0.5 ## A handle for your relay, so people don't have to refer to it by key. ## Nicknames must be between 1 and 19 characters inclusive, and must ## contain only the characters [a-zA-Z0-9]. ## If not set, "Unnamed" will be used. #Nickname ididnteditheconfig ## Define these to limit how much relayed traffic you will allow. Your ## own traffic is still unthrottled. Note that RelayBandwidthRate must ## be at least 75 kilobytes per second. ## Note that units for these config options are bytes (per second), not ## bits (per second), and that prefixes are binary prefixes, i.e. 2^10, ## 2^20, etc. #RelayBandwidthRate 100 KBytes # Throttle traffic to 100KB/s (800Kbps) #RelayBandwidthBurst 200 KBytes # But allow bursts up to 200KB (1600Kb) ## Use these to restrict the maximum traffic per day, week, or month. ## Note that this threshold applies separately to sent and received bytes, ## not to their sum: setting "40 GB" may allow up to 80 GB total before ## hibernating. ## ## Set a maximum of 40 gigabytes each way per period. #AccountingMax 40 GBytes ## Each period starts daily at midnight (AccountingMax is per day) #AccountingStart day 00:00 ## Each period starts on the 3rd of the month at 15:00 (AccountingMax ## is per month) #AccountingStart month 3 15:00 ## Administrative contact information for this relay or bridge.

Now you ## can explain what Tor is if anybody wonders why your IP address is ## contacting them. See contrib/tor-exit-notice.html in Tor's source ## distribution for a sample. #DirPortFrontPage /etc/tor/tor-exit-notice.html ## Uncomment this if you run more than one Tor relay, and add the identity ## key fingerprint of each Tor relay you control, even if they're on ## different networks. You declare it here so Tor clients can avoid ## using more than one of your relays in a single circuit. See ## https://www.torproject.org/docs/faq#MultipleRelays ## However, you should never include a bridge's fingerprint here, as it would ## break its concealability and potentially reveal its IP/TCP address. ## ## If you are running multiple relays, you MUST set this option. ## ## Note: do not use MyFamily on bridge relays. #MyFamily $keyid,$keyid,... ## Uncomment this if you want your relay to be an exit, with the default ## exit policy (or whatever exit policy you set below). ## (If ReducedExitPolicy, ExitPolicy, or IPv6Exit are set, relays are exits. ## If none of these options are set, relays are non-exits.) #ExitRelay 1 ## Uncomment this if you want your relay to allow IPv6 exit traffic. ## (Relays do not allow any exit traffic by default.) #IPv6Exit 1 ## Uncomment this if you want your relay to be an exit, with a reduced set ## of exit ports. #ReducedExitPolicy 1 ## Uncomment these lines if you want your relay to be an exit, with the ## specified set of exit IPs and ports. ## ## A comma-separated list of exit policies. They're considered first ## to last, and the first match wins. ## ## If you want to allow the same ports on IPv4 and IPv6, write your rules ## using accept/reject *. If you want to allow different ports on IPv4 and ## IPv6, write your IPv6 rules using accept6/reject6 *6, and your IPv4 rules ## using accept/reject *4. ## ## If you want to _replace_ the default exit policy, end this with either a ## reject *:* or an accept *:*. Otherwise, you're _augmenting_ (prepending to) ## the default exit policy. Leave commented to just use the default, which is ## described in the man page or at ## https://www.torproject.org/documentation.html ## ## Look at https://www.torproject.org/faq-abuse.html#TypicalAbuses ## for issues you might encounter if you use the default exit policy. ## ## If certain IPs and ports are blocked externally, e.g. by your firewall, ## you should update your exit policy to reflect this -- otherwise Tor ## users will be told that those destinations are down. ## ## For security, by default Tor rejects connections to private (local) ## networks, including to the configured primary public IPv4 and IPv6 addresses, ## and any public IPv4 and IPv6 addresses on any interface on the relay. ## See the man page entry for ExitPolicyRejectPrivate if you want to allow ## "exit enclaving". ## #ExitPolicy accept *:6660-6667,reject *:* # allow irc ports on IPv4 and IPv6 but no more #ExitPolicy accept *:119 # accept nntp ports on IPv4 and IPv6 as well as default exit policy #ExitPolicy accept *4:119 # accept nntp ports on IPv4 only as well as default exit policy #ExitPolicy accept6 *6:119 # accept nntp ports on IPv6 only as well as default exit policy #ExitPolicy reject *:* # no exits allowed ## Bridge relays (or "bridges") are Tor relays that aren't listed in the ## main directory. Since there is no complete public list of them, even an ## ISP that filters connections to all the known Tor relays probably ## won't be able to block all the bridges. Also, websites won't treat you ## differently because they won't know you're running Tor. If you can ## be a real relay, please do; but if not, be a bridge! ## ## Warning: when running your Tor as a bridge, make sure than MyFamily is ## NOT configured. #BridgeRelay 1 ## By default, Tor will advertise your bridge to users through various ## mechanisms like https://bridges.torproject.org/. If you want to run ## a private bridge, for example because you'll give out your bridge ## address manually to your friends, uncomment this line: #PublishServerDescriptor 0 ## Configuration options can be imported from files or folders using the %include ## option with the value being a path. If the path is a file, the options from the ## file will be parsed as if they were written where the %include option is. If ## the path is a folder, all files on that folder will be parsed following lexical ## order. Files starting with a dot are ignored. Files on subfolders are ignored. ## The %include option can be used recursively. #%include /etc/torrc.d/ #%include /etc/torrc.custom |
