Are you a Linux user looking to rename your network interface from ‘ens’ to ‘eth’? Or perhaps you need to configure your DNS settings for a more seamless internet experience? Well, you’ve come to the right place. In this article, I’ll guide you through the process of renaming your network interface and setting up your DNS in a detailed and easy-to-follow manner.
Renaming Your Network Interface
Renaming your network interface is a straightforward process, but it requires a bit of command-line magic. Here’s how you can do it:
- Open your terminal.
- Use the ‘ip’ command to list all your network interfaces. Type ‘ip addr show’ and press Enter.
- Identify the interface you want to rename. It will be listed as ‘ensXX’, where ‘XX’ is a number.
- Use the ‘nmcli’ command to set the new name for your interface. Type ‘nmcli con mod
ifname ‘ and press Enter. Replace ‘ ‘ with the name of your interface and ‘ ‘ with the name you want to assign to it. - For example, if you want to rename ‘ens33’ to ‘eth0’, you would type ‘nmcli con mod ens33 ifname eth0’ and press Enter.
- Restart your network interface to apply the changes. Type ‘nmcli con down
‘ and press Enter, followed by ‘nmcli con up ‘.
And voil脿! Your network interface should now be renamed to ‘eth0’ or whatever name you chose.
Configuring Your DNS Settings
Configuring your DNS settings is equally important, as it determines how your computer resolves domain names to IP addresses. Here’s how you can set up your DNS:
- Open your terminal.
- Use the ‘cat’ command to list the current DNS settings. Type ‘cat /etc/resolv.conf’ and press Enter.
- Identify the current DNS servers. They will be listed under the ‘nameserver’ keyword.
- Use the ‘echo’ command to set your new DNS servers. Type ‘echo “nameserver
” > /etc/resolv.conf’ and press Enter, replacing ‘ ‘ with the IP address of your preferred DNS server. - Repeat step 3 for each DNS server you want to use. For example, if you want to use Google’s public DNS servers, you would type ‘echo “nameserver 8.8.8.8” > /etc/resolv.conf’ and press Enter, followed by ‘echo “nameserver 8.8.4.4” >> /etc/resolv.conf’.
- Save and close the file.
Your DNS settings should now be updated. To verify, you can use the ‘nslookup’ command to test your DNS resolution. Type ‘nslookup google.com’ and press Enter. If everything is working correctly, you should see the IP address of Google’s DNS server.
Additional Tips
Here are a few additional tips to help you along the way:
- Remember to replace ‘
‘ and ‘ ‘ with the actual names and IP addresses in your case. - Always back up your configuration files before making changes.
- Consult your system’s documentation or seek help from online forums if you encounter any issues.
By following these steps, you should be able to rename your network interface and configure your DNS settings with ease. Happy networking!
