Configure unbound and hblock to enhance privacy and block ads in Linux
There is an android app named Adaway, which automatically updates your system hosts file to redirect ads domain to localhost.
However, changing hosts file on linux can cause problems, because when you autocomplete shell commands like ssh and nmap, domains in hosts file will be pulled, which generates a lot of lag since there are way too many. One good way to work around this is to add blocklist in your dns server instead.
Since I don't see many info around the web that covers these setups, I decided to write it myself and explain the incentives along the way.
TLDR:
- Unbound: the privacy-centric DNS server
- Hblock: Ad blocking script
