You can block specific websites, including casino sites, on Lubuntu by modifying your DNS settings or by editing the
/etc/hosts file. Below are the steps for each method:
### Method 1: Using DNS
1.
Use a Family Safety DNS: There are DNS providers like OpenDNS which allow you to block specific categories of websites, including gambling websites. Here are the steps to set it up:
- Go to "Settings" > "Network".
- Click on "Settings" for your current network.
- Go to the "IPv4" or "IPv6" tab.
- Select "Automatic (DHCP) addresses only" or "Manual" from the dropdown.
- Enter the DNS addresses provided by the DNS provider. For example, OpenDNS Family Shield DNS IPs are
208.67.222.123 and
208.67.220.123.
- Click "Apply".
- Restart the network manager with the command:
sudo service network-manager restart.
2.
Create a Custom DNS Server: This is more complicated but gives you full control over the blocked sites. You would need to set up a DNS server, configure it to block specific sites, and then point your Lubuntu machine to use this DNS server.
### Method 2: Editing the /etc/hosts File
1.
Open Terminal: You can open it by pressing
CTRL +
ALT +
T or by searching for it.
2.
Edit the /etc/hosts File: Use a text editor to open and edit the file. For example, you can use nano by entering the following command:
Code:
bash
sudo nano /etc/hosts
3.
Add the Websites You Want to Block: At the bottom of the file, add the sites you want to block, pointing them to the local address
127.0.0.1. For example, to block
examplecasinosite.com, add the following line:
Code:
plaintext
127.0.0.1 examplecasinosite.com
4.
Save and Close the File: If you are using nano, press
CTRL +
X, then press
Y to confirm the changes, and press
Enter.
5.
Flush the DNS Cache: You can do this by restarting your computer or by entering the following command:
Code:
bash
sudo systemd-resolve --flush-caches
Remember to replace "examplecasinosite.com" with the actual URL of the casino or gambling site you wish to block. You can add as many sites as you want by adding more lines.
Please note that users can bypass this method by using a VPN or proxy, or by changing the DNS settings on their device to use a different DNS service.
