tor - The second-generation onion router

<H2>SYNOPSIS</H2>
<B>tor</B>
[<I>OPTION value</I>]...
<A NAME="lbAD"> </A>
<H2>DESCRIPTION</H2>
<I>tor</I>
is a connection-oriented anonymizing communication
service. Users choose a source-routed path through a set of nodes, and
negotiate a "virtual circuit" through the network, in which each node
knows its predecessor and successor, but no others. Traffic flowing down
the circuit is unwrapped by a symmetric key at each node, which reveals
the downstream node.
<P>
Basically <I>tor</I> provides a distributed network of servers ("onion
routers"). Users bounce their TCP streams -- web traffic, ftp, ssh, etc --
around the routers, and recipients, observers, and even the routers
themselves have difficulty tracking the source of the stream.
