Hostsblock is a bash script for Linux designed to take advantage of the /etc/hosts file to provide system-wide blocking of internet advertisements, malicious domains, trackers, and other undesirable content. To do so, it downloads a configurable set of blocklists and processes and their entries into a singular file. The SlackBuild assumes that dnsmasq is not available so it will configure hostsblock to overwrite the current /etc/hosts file. The install script will backup the current /etc/hosts file to /etc/hostsblock/hosts.head if it does not already exist. After uninstalling hostsblock, you should copy hosts.head back to /etc/hosts. To have hostsblock automatically update /etc/hosts once a week, run: ln -sf /usr/sbin/hostsblock /etc/cron.weekly/hostsblock
