How to Add TXT Record to DNS Configuration in Linux

The Domain Name System (DNS) is an essential component of the internet that translates human-readable domain names into IP addresses. DNS records are used to specify how a domain name should be resolved to an IP address. A TXT record is one type of DNS record that is used to provide text information about a domain. In this article, we will guide you on how to add a TXT record to DNS configuration in Linux.

Before we begin, you will need access to a Linux server and root or sudo privileges. We will be using the terminal to execute commands.

Step 1: Connect to your Linux server

To get started, connect to your Linux server using SSH or any other remote access method.

Step 2: Install the DNS utilities

You will need to have the DNS utilities installed on your server to manage DNS records. If you are using Ubuntu or Debian, you can install the DNS utilities by running the following command:

sudo apt-get install dnsutils

If you are using a different Linux distribution, you can install the DNS utilities using the appropriate package manager.

Step 3: Add a TXT record

To add a TXT record, you will need to know the domain name and the value you want to assign to the record. The following command will add a TXT record for the domain example.com with the value "This is a sample TXT record":

sudo nsupdate -v -d << EOF
server dns.example.com
zone example.com
update add example.com 86400 IN TXT "This is a sample TXT record"
send
EOF

Replace dns.example.com with the hostname of your DNS server and example.com with your domain name.

Step 4: Verify the TXT record

You can use the following command to verify that the TXT record has been added:

dig example.com txt

This command will display the TXT record for the domain example.com.

More Examples:

  • To update an existing TXT record, replace "update add" with "update".
  • To delete a TXT record, replace "update add" with "update delete".

In this article, we have shown you how to add a TXT record to DNS configuration in Linux. By following the above steps, you can easily manage DNS records on your Linux server.
