Daemon quick overview

History & use

The daemon was introduced in TBlock version 2.0.0. It is a simple utility that runs in background and that can perform the following tasks:

• Update the filter lists (and sync the repository index) at a regular time interval
• Protect the hosts file against being edited by another program or user

Multiple instances

By default, only one instance of the daemon can run at the same time. When an instance of the daemon starts, it creates a PID file, and, if the file already exists then it fails to start. The PID file is removed when the instance of the running daemon stops.
