# HB
|
|
|
|
The Host Blocker command.
|
|
|
|
This is a system utility written in C that allows one to quickly black hole hosts in the /etc/hosts file, keeping one from resolving any DNS for those hosts and permanently blocking them on the system.
|
|
|
|
# How it Works
|
|
|
|
The program "blackholes" hosts by setting their entries in /etc/hosts to be
|
|
`0.0.0.0` so that when one tries to resolve the host in the browser the host will
|
|
resolve to `0.0.0.0`.
|
|
|
|
The program will wake up in a configurable timeframe continuously, reading a config file into memory and making appropriate changes to the /etc/hosts based on what it reads from the config.
|
|
|
|
Starting the program like this allows for the program to run as a daemon:
|
|
|
|
```bash
|
|
sudo hb -period <wakeup period> -config <path/to/config> -daemon
|
|
```
|
|
|
|
The config file at the moment is just a newline separated list of hosts that will
|
|
be added to the /etc/hosts file.
|
|

# Motivations
|
|
|
|
I would like to get better with C, and will be using C much more in the near future. In addition, I have issues with browsing to sites that hurt my productivity and am always on the command line.

# TODO

|
|
- Debug logging
|
|
- Systemd unit file for running as a daemon
