Command-line utility to control Tor.




carml is a command-line tool to query and control a running Tor (including Tor Browser Bundle). You can do things like:

  • list and remove streams and circuits;
  • monitor stream, circuit and address-map events;
  • watch for any Tor event and print it (or many) out;
  • monitor bandwidth;
  • run any Tor control-protocol command;
  • pipe through common Unix tools like grep, less, cut, etcetera;
  • download TBB through Tor, with pinned certs and signature checking;
  • ...even spit out and run xplanet configs (with router/circuit markers)!

It is written in Python and uses Tor's control-port via the txtorcon library <>_.

In some ways, carml started as a dumping-ground for things I happened to make Tor do at least once from Python code. Are there things you wish you could easily make Tor do from the command-line? File an enhancement bug at GitHub!

carml is also easy to extend, even with system- or virtualenv <>_- installed packages.

Feedback is appreciated -- pull-requests and bug-reports (including feature enhancements) welcome at GitHub <> or you can contact me in #tor-dev on OFTC <irc://> or via meejah at meejah dot ca with the public-key contained in the source.
