Setting up the server

• First create a server (proper port management should be done)
• Now first disable the internal dns server by executing sudo systemctl stop systemd-resolved.service and sudo systemctl disable systemd-resolved.service.
• Now as the dns is disabled the server will not be able to resolve any domain. So, to resolve this we change the /etc/resolv.conf file. There beside the nameserver word we add 8.8.8.8 which is the google dns.
• Now execute git clone https://github.com/Souptik2001/piholedocker.git. This will download a piholedocker named folder.
• Move to that directory and give executable permission to the pihole.sh file and then just run that file like sudo pihole.sh.
• And now your pihole server is ready and you can find it at http://ip_addr and log in using the auto password dispalyed at the last. To change this password enter into the container by executing sudo docker exec -it pihole bash and then execute sudo pihole -a -p.
• Now if you enter into the container and move to /home/network you will find a bunch of files. Now run sudo python3 network.py. Now you will get two apis http://ip_addr:8080/block and http://ip_addr:8080/unblock to block and unblock some sites. You can change the sites to be blocked and unblocked by changing the files blockdomains.sh and unblockdomains.sh.
• And that's it completly ready.

Bonus

• You can take this thing one step further.
• First run this network.py in background by sudo nohup python3 network.py > log.txt 2>&1 &.
• And then you can use IFTTT and trigger these two apis using any voice assistant like google assistant, alexa or anything.
