TOR SUPPORT IN ZCASH

+It is possible to run Komodo 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

-1. Run Zcash behind a Tor proxy
+1. Run Komodo behind a Tor proxy
-------------------------------
-The first step is running Zcash behind a Tor proxy. This will already make all
+The first step is running Komodo 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
In a typical situation, this suffices to run behind a Tor proxy:
- ./zcashd -proxy=127.0.0.1:9050
+ ./komodod -proxy=127.0.0.1:9050
-2. Run a Zcash hidden server
+2. Run a Komodo hidden server
----------------------------
If you configure your Tor system accordingly, it is possible to make your node also
config file):
HiddenServiceDir /var/lib/tor/zcash-service/
- HiddenServicePort 8233 127.0.0.1:8233
- HiddenServicePort 18233 127.0.0.1:18233
+ HiddenServicePort 7771 127.0.0.1:7771
+ HiddenServicePort 17771 127.0.0.1:17771
The directory can be different of course, but (both) port numbers should be equal to
-your zcashd's P2P listen port (8233 by default).
+your komodod's P2P listen port (7771 by default).
- -externalip=X You can tell Zcash about its publicly reachable address using
+ -externalip=X You can tell Komodo 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/zcash-service/hostname. Onion addresses are given
In a typical situation, where you're only reachable via Tor, this should suffice:
- ./zcashd -proxy=127.0.0.1:9050 -externalip=zctestseie6wxgio.onion -listen
+ ./komodod -proxy=127.0.0.1:9050 -externalip=zctestseie6wxgio.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:
+
+ ./zcashd ... -bind=127.0.0.1
-(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:
+If you don't care too much about hiding your node, and want to be reachable on IPv4
+as well, use `discover` instead:
- ./zcashd ... -discover
+ ./komodod ... -discover
-and open port 8233 on your firewall (or use -upnp).
+and open port 7771 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:
- ./zcashd -onion=127.0.0.1:9050 -externalip=zctestseie6wxgio.onion -discover
+ ./komodod -onion=127.0.0.1:9050 -externalip=zctestseie6wxgio.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.
-Zcash has been updated to make use of this.
-
-This means that if Tor is running (and proper authorization is available),
-Zcash 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 Zcash 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`.
-
-
-4. Connect to a Zcash hidden server
+Komodo has been updated to make use of this.
+
+This means that if Tor is running (and proper authentication has been configured),
+Komodo automatically creates a hidden service to listen on. Komodo will also use Tor
+automatically to connect to other .onion nodes if the control socket can be
+successfully opened. This will positively affect the number of available .onion
+nodes and their usage.
+
+This new feature is enabled by default if Komodo is listening (`-listen`), and
+requires a Tor connection to work. It can be explicitly disabled with `-listenonion=0`
+and, if not disabled, configured using the `-torcontrol` and `-torpassword` settings.
+To show verbose debugging information, pass `-debug=tor`.
+
+Connecting to Tor's control socket API requires one of two authentication methods to be
+configured. For cookie authentication the user running komodod must have write access
+to the `CookieAuthFile` specified in Tor configuration. In some cases this is
+preconfigured and the creation of a hidden service is automatic. If permission problems
+are seen with `-debug=tor` they can be resolved by adding both the user running tor and
+the user running komodod to the same group and setting permissions appropriately. On
+Debian-based systems the user running komodod can be added to the debian-tor group,
+which has the appropriate permissions. An alternative authentication method is the use
+of the `-torpassword` flag and a `hash-password` which can be enabled and specified in
+Tor configuration.
+
+
+4. Connect to a Komodo hidden server
-----------------------------------
To test your set-up, you might want to try connecting via Tor on a different computer to just a
-a single Zcash hidden server. Launch zcashd as follows:
+a single Komodo hidden server. Launch komodod as follows:
- ./zcashd -onion=127.0.0.1:9050 -connect=zctestseie6wxgio.onion
+ ./komodod -onion=127.0.0.1:9050 -connect=zctestseie6wxgio.onion
-Now use zcash-cli to verify there is only a single peer connection.
+Now use komodo-cli to verify there is only a single peer connection.
- zcash-cli getpeerinfo
+ komodo-cli getpeerinfo
[
{
"id" : 1,
- "addr" : "zctestseie6wxgio.onion:18233",
+ "addr" : "zctestseie6wxgio.onion:17770",
...
"version" : 170002,
"subver" : "/MagicBean:1.0.0/",
To connect to multiple Tor nodes, use:
- ./zcashd -onion=127.0.0.1:9050 -addnode=zctestseie6wxgio.onion -dnsseed=0 -onlynet=onion
+ ./komodod -onion=127.0.0.1:9050 -addnode=zctestseie6wxgio.onion -dnsseed=0 -onlynet=onion
