'tor' is an implementation of The Onion Routing system, as described in a bit more detail at http://www.onion-router.net/. You can read list archives, and subscribe to the mailing list, at http://archives.seul.org/or/dev/. Is your question in the FAQ? Should it be? ************************************************************************** See the INSTALL file for a quickstart. That is all you will probably need. ************************************************************************** ************************************************************************** You only need to look beyond this point if the quickstart in the INSTALL doesn't work for you. ************************************************************************** Do you want to run a tor server? We're looking for people with reasonably reliable Internet connections, that have at least 768kbit each way. Currently we don't use all of that, but we want it available for burst traffic. First, copy torrc.sample to torrc (by default it's in /usr/local/etc/tor/), and edit the middle part. Create the DataDirectory, and make sure it's owned by whoever will be running tor. Fix your system clock so it's not too far off. Make sure name resolution works. Then run tor to generate keys. One of the files generated in your DataDirectory is your 'fingerprint' file. Mail it to arma@mit.edu. NOTE: You won't be able to use tor as a client or server in this configuration until you've been added to the directory and can authenticate to the other nodes. Do you want to run a hidden service? Copy torrc.sample to torrc (by default it's in /usr/local/etc/tor/), and edit the bottom part. Then run Tor. It will create each HiddenServiceDir you have configured, and it will create a 'hostname' file which specifies the url (xyz.onion) for that service. You can tell people the url, and they can connect to it via their Tor proxy. Configuring tsocks: If you want to use Tor for protocols that can't use Privoxy, or with applications that are not socksified, then download tsocks (tsocks.sourceforge.net) and configure it to talk to localhost:9050 as a socks4 server. My /etc/tsocks.conf simply has: server_port = 9050 server = 127.0.0.1 (I had to "cd /usr/lib; ln -s /lib/libtsocks.so" to get the tsocks library working after install, since my libpath didn't include /lib.) Then you can do "tsocks ssh arma@moria.mit.edu". But note that if ssh is suid root, you either need to do this as root, or cp a local version of ssh that isn't suid.
