Overview
exitmap is a fast and modular Python-based scanner for Tor exit relays.
Modules implement tasks which can be executed over (a subset of) all exit
relays.
The tool uses Stem to initiate circuits over
all given exit relays and as soon as tor notifies exitmap of an established
circuit, a module is invoked for the newly established circuit.
exitmap has been used to check for false positives on the Tor Project's
check service and to find malicious exit
relays.
Installation
exitmap uses the library Stem to communicate with Tor. On Debian jessie
and newer, you can install Stem by executing:
# apt-get install python-stem
Running exitmap
You can run exitmap with the checktest module by executing:
$ python exitmap.py CCEF02AA454C0AB0FE1AC68304F6D8C4220C1912 checktest
To run the same test over German exit relays only, execute:
$ python exitmap.py -C DE CCEF02AA454C0AB0FE1AC68304F6D8C4220C1912 checktest
Note that
CCEF02AA454C0AB0FE1AC68304F6D8C4220C1912
is a relay run by Karlstad University. While you can feel free to use it,
please use your own relays in order to distribute the scanning load.
