TOR SUPPORT IN NEOBYTES CORE ============================ It is possible to run Neobytes Core as a Tor hidden service, and connect to such services. The following directions assume you have a Tor proxy running on port 9050. Many distributions default to having a SOCKS proxy listening on port 9050, but others may not. In particular, the Tor Browser Bundle defaults to listening on a random port. See [Tor Project FAQ:TBBSocksPort](https://www.torproject.org/docs/faq.html.en#TBBSocksPort) for how to properly configure Tor. 1. Run Neobytes Core behind a Tor proxy --------------------------------------- The first step is running Neobytes Core behind a Tor proxy. This will already make all outgoing connections be anonymized, but more is possible. -proxy=ip:port Set the proxy server. If SOCKS5 is selected (default), this proxy server will be used to try to reach .onion addresses as well. -onion=ip:port Set the proxy server to use for tor hidden services. You do not need to set this if it's the same as -proxy. You can use -noonion to explicitly disable access to hidden service. -listen When using -proxy, listening is disabled by default. If you want to run a hidden service (see next section), you'll need to enable it explicitly. -connect=X When behind a Tor proxy, you can specify .onion addresses instead -addnode=X of IP addresses or hostnames in these parameters. It requires -seednode=X SOCKS5. In Tor mode, such addresses can also be exchanged with other P2P nodes. -onlynet=tor Only connect to .onion nodes and drop IPv4/6 connections. An example how to start the client if the Tor proxy is running on local host on port 9050 and only allows .onion nodes to connect: ./neobytesd -onion=127.0.0.1:9050 -onlynet=tor -listen=0 -addnode=ssapp53tmftyjmjb.onion In a typical situation, this suffices to run behind a Tor proxy: ./neobytesd -proxy=127.0.0.1:9050 2. Run a Neobytes Core hidden server ------------------------------------ If you configure your Tor system accordingly, it is possible to make your node also reachable from the Tor network. Add these lines to your /etc/tor/torrc (or equivalent config file): HiddenServiceDir /var/lib/tor/neobytes-service/ HiddenServicePort 1428 127.0.0.1:1428 HiddenServicePort 11428 127.0.0.1:11428 The directory can be different of course, but (both) port numbers should be equal to your neobytesd's P2P listen port (1428 by default). -externalip=X You can tell Neobytes Core about its publicly reachable address using this option, and this can be a .onion address. Given the above configuration, you can find your onion address in /var/lib/tor/neobytes-service/hostname. Onion addresses are given preference for your node to advertise itself with, for connections coming from unroutable addresses (such as 127.0.0.1, where the Tor proxy typically runs). -listen You'll need to enable listening for incoming connections, as this is off by default behind a proxy. -discover When -externalip is specified, no attempt is made to discover local IPv4 or IPv6 addresses. If you want to run a dual stack, reachable from both Tor and IPv4 (or IPv6), you'll need to either pass your other addresses using -externalip, or explicitly enable -discover. Note that both addresses of a dual-stack system may be easily linkable using traffic analysis. In a typical situation, where you're only reachable via Tor, this should suffice: ./neobytesd -proxy=127.0.0.1:9050 -externalip=ssapp53tmftyjmjb.onion -listen (obviously, replace the Onion address with your own). It should be noted that you still listen on all devices and another node could establish a clearnet connection, when knowing your address. To mitigate this, additionally bind the address of your Tor proxy: ./neobytesd ... -bind=127.0.0.1 If you don't care too much about hiding your node, and want to be reachable on IPv4 as well, use `discover` instead: ./neobytesd ... -discover and open port 1428 on your firewall (or use -upnp). If you only want to use Tor to reach onion addresses, but not use it as a proxy for normal IPv4/IPv6 communication, use: ./neobytesd -onion=127.0.0.1:9050 -externalip=ssapp53tmftyjmjb.onion -discover 3.

Automatically listen on Tor -------------------------------- Starting with Tor version 0.2.7.1 it is possible, through Tor's control socket API, to create and destroy 'ephemeral' hidden services programmatically. Neobytes Core has been updated to make use of this. This means that if Tor is running (and proper authorization is available), Neobytes Core automatically creates a hidden service to listen on, without manual configuration. This will positively affect the number of available .onion nodes. This new feature is enabled by default if Neobytes Core is listening, and a connection to Tor can be made. It can be configured with the `-listenonion`, `-torcontrol` and `-torpassword` settings. To show verbose debugging information, pass `-debug=tor`.
