The simplest way to get exposure to SpyBye is to configure your browser to use http://www.spybye.org:8080/ as proxy. However, this is likely to be slow as your are sharing the proxy with other users and are constrained by the limited bandwidth in my closet. You can now download the SpyBye software yourself from http://www.monkey.org/~provos/spybye/ and run it on your own servers.
For detailed installation instructions, please consult the following article. Hopefully, there is enough information there, to get you up and running in a matter of minutes.
