This is chutney. It doesn't do much so far. It isn't ready for prime-time.
If it breaks, you get to keep all the pieces.
It is supposed to be a good tool for:
- Configuring a testing tor network
- Launching and monitoring a testing tor network
- Running tests on a testing tor network
Right now it only sorta does these things.
You will need, at the moment:
- Tor installed somewhere in your path or the location of the 'tor' and
'tor-gencert' binaries specified through the environment variables
CHUTNEY_TOR and CHUTNEY_TOR_GENCERT, respectively.
- Python 2.7 or later
Stuff to try:
Standard Actions:
./chutney configure networks/basic
./chutney start networks/basic
./chutney status networks/basic
./chutney verify networks/basic
./chutney hup networks/basic
./chutney stop networks/basic
Bandwidth Tests:
./chutney configure networks/basic-min
./chutney start networks/basic-min
./chutney status networks/basic-min
CHUTNEY_DATA_BYTES=104857600 ./chutney verify networks/basic-min
# Send 100MB of data per client connection
# verify produces performance figures for:
# Single Stream Bandwidth: the speed of the slowest stream, end-to-end
# Overall tor Bandwidth: the sum of the bandwidth across each tor instance
# This approximates the CPU-bound tor performance on the current machine,
# assuming everything is multithreaded and network performance is infinite.
./chutney stop networks/basic-min
Connection Tests:
./chutney configure networks/basic-025
./chutney start networks/basic-025
./chutney status networks/basic-025
CHUTNEY_CONNECTIONS=5 ./chutney verify networks/basic-025
# Make 5 connections from each client through a random exit
./chutney stop networks/basic-025
Note: If you create 7 or more connections to a hidden service from a single
client, you'll likely get a verification failure due to
https://trac.torproject.org/projects/tor/ticket/15937
HS Connection Tests:
./chutney configure networks/hs-025
./chutney start networks/hs-025
./chutney status networks/hs-025
CHUTNEY_HS_MULTI_CLIENT=1 ./chutney verify networks/hs-025
# Make a connection from each client to each hs
# Default behavior is one client connects to each HS
./chutney stop networks/hs-025
The configuration files:
networks/basic holds the configuration for the network you're configuring
above. It refers to some torrc template files in torrc_templates/.
The working files:
chutney sticks its working files, including all data directories, log
files, etc, in ./net/. Each tor instance gets a subdirectory of net/nodes.
