Hostsblock is a POSIX-compatible script for Linux designed to take advantage of the HOSTS file available in all operating systems to provide system-wide blocking of internet advertisements, malicious domains, trackers, and other undesirable content.
Hostsblock also provides a command-line utility that allows you to configure how individual websites and any other domains contained in that website are handled.
This is free and open source software.
Features include:
- System-wide blocking (all non-proxied connections use the HOSTS file).
- Zip- and 7zip-capable (can download and process zip- and 7zip-compressed files).
- Non-interactive (can be run as a periodic cronjob without needing user interaction).
- Extensive configurability (allows for custom black and white listing, redirection, post-processing scripting, target HOSTS file, etc.).
- Bandwidth-efficient (only downloads blocklists that have been changed, uses compression when available).
- Resource-efficient (only processes blocklists when changes are registered, uses minimal pipes).
- High performance blocking (when using DNS caching and pseudo-server daemons).
- Extensive choice of blocklists included (allows user to customize how much or how little is blocked).
- Redirection capability (combats DNS cache poisoning).
