Redirector starts a web server that listens at standard port 80. It searches /etc/hosts file for lines matching ::1 hostname #redirects-to url pattern. When you type hostname in your browser, browser hits your machine (::1 is ipv6's 127.0.0.1) on which redirector is there to give you HTTP redirect to url.

It may be useful when you don't have your own DNS server, or all you have is OpenWRT's dnsmasq which doesn't support CNAME records.

If you have a choice, ditch the nasty hack redirector is and use DNS.

1. Edit your /etc/hosts file. Add entries like

::1 g #redirects-to http://gazeta.pl
::1 m #redirects-to https://mail.google.com
::1 cups #redirects-to http://localhost:631
::1 reddit.com www.reddit.com #redirects-to http://localhost:8080/stop-slacking-off

2. Install redirector

make
sudo make install

3. Run it

sudo systemctl start redirector.service

4. Make it start on system start

sudo systemctl enable redirector.service
