![]() To run the script for custom domains, add them to the config/cescout.cfg file. Measurements are fetched for Wikimedia domains by default, as specified in config/cescout.cfg. A measurement is marked as anomalous if the blocking type is not false (examples: dns or tcp_ip). Queries (a local copy of) OONI's metadb for specified domains (see config/cescout.cfg) to check for anomalous measurements. To override the system-wide settings, copy the files from /etc/cescout (or config/) to $HOME/.config/cescout and edit as required. ![]() Configuration Fileĭuring installation, the script copies the configuration files to /etc/cescout. Additional arguments may be required depending on the project, such as -asns (list of ASNs) for running the RIPE test. $ cescout -country CN -since -skip-ioda -skip-ripe -raw | python3 -m json.toolĪll projects take as input a two-letter country code and a time period to run the query for, specified by -since and -until (the current time is assumed if -until is not passed). Note that this requires 700GB+ of disk space as it has all current and historic OONI measurements. Python 3.7 and some additional libraries see requirements.txt in the root folder for a complete list.įor the OONI tests, a copy of OONI's metadb is required please see the OONI documentation at for instructions on how to set up a replica. cescout does not perform any internet measurements by itself.Ĭurrently it queries the following projects: OONI (), for information about censorship of websites IODA (), for internet outages (and shutdowns) and RIPE (), to fetch routing information that is used to correlate information from OONI and IODA. It serves as an interface to collect data from different projects to identify such events in a given country and uses that information to generate a report that helps distinguish between censorship of particular websites from broader internet outages or shutdowns. Cescout is a censorship monitoring toolkit that queries multiple internet measurement projects to identify censorship events and internet outages.
