How to Install dig on a CentOS Linux Server?
Installing dig on a CentOS Linux server is easy with yum. Dig is actually a bind tool so you will be required to install some bind libraries along with the bind utility package.
1 | [root@server ~]# yum install bind-utils |
Now you can run something like the below using dig to find MX records.
1 | [root@server ~]# dig @NAMESERVER EXAMPLE.COM MX |
Your install will look something like the below showing how yum looks for dependencies and installs them automatically.
