The censorship tools are a collection of bash scripts for comparing DNS server answers to get the blacklist from the censored server and to make the DNS censorship transparent; downloading censored URLs for teasing the censorship or tuning of censorship statistics; and other functions like opening all censored pages of a blacklist with a browser (e. g. with CensoRaser), and perform rDNS lookup of the sites to which the traffic to censored sites is redirected.
