NAME
pathspider - Internet Path Transparency Measurement Tool
SYNOPSIS
usage: pathspider [-h] [-s] [-i INTERFACE] [-w WORKERS] [--input INPUTFILE] [--output OUTPUTFILE] [-v] PLUGIN ...
DESCRIPTION
For each target PATHspider enqueues a job, to be distributed amongst the worker threads when available. Each worker performs one connection with the “A” configuration and one connection with the “B” configuration. The “A” configuration will always be connected first and serves as the base line measurement, followed by the “B” configuration.

EXAMPLES
You can run a small study using ECNSpider and the included webinput.csv file to measure path transparency to ECN for a small selection of web servers:
# pathspider -i eth0 ecn \
</usr/share/doc/pathspider/examples/webinput.csv \
>/tmp/results.txt
