ERROR :

*WARNING* Binary location for [HOST] [/usr/bin/host] in /etc/csf/csf.conf is either incorrect, is not installed or is not executable

FIX :

I saw the above warning while restarting CSF firewall on my server. Do the below steps to fix the error.

1. Log into your Linux server as root user

2 Check whether bind-utils package is installed or not, on my cPanel server it was not installed.

host command is provided by bind-utils package.

-bash: /usr/bin/host: No such file or directory

Command to check whether bind-utils is installed or not :

# rpm -qa | grep bind-utils

4. Install bind-utils package using yum.
 

[root@server ~]# yum install bind-utils

–> Running transaction check
—> Package bind-utils.x86_64 32:9.9.4-29.el7_2.3 will be installed

Running transaction

Dependency Installed:

Now bind-utils is installed and the CSF warning should be fixed.
