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 novacoin behind a Tor proxy +--------------------------------- + +The first step is running Novacoin 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. + +In a typical situation, this suffices to run behind a Tor proxy: + + ./novacoin -proxy=127.0.0.1:9050 + + +2. Run a novacoin 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/novacoin-service/ + HiddenServicePort 7777 127.0.0.1:7777 + HiddenServicePort 17777 127.0.0.1:17777 + +The directory can be different of course, but (both) port numbers should be equal to +your novacoind's P2P listen port (7777 by default, 17777 by default for testnet). + + -externalip=X You can tell novacoin 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/novacoin-service/hostname. Onion addresses are given + preference for your node to advertize 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: + + ./novacoind -proxy=127.0.0.1:9050 -externalip=youraddress.onion -listen + +(obviously, replace the Onion address with your own). If you don't care too much +about hiding your node, and want to be reachable on IPv4 as well, additionally +specify: + + ./novacoind ... -discover + +and open port 7777 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: + + ./novacoin -onion=127.0.0.1:9050 -externalip=youraddress.onion -discover + +Known addresses of novacoin nodes + + seedp4knqnoei57u.onion + seedr3hhlepyi7fd.onion + seed3uuomkclbiz4.onion + seedeh7qck3ouff5.onion + seedt3sraf53ajiy.onion + seedg4qyccsg42oq.onion + novaqrtoywpg7jly.onion + seed3d5wolqbgrcb.onion + seed24u5dwph3qw4.onion + mj26ulzbs2oskgym.onion + eqon4usunavt76m7.onion + 5rg3vq4jagckeckf.onion
