Linux : Binary location for [/usr/bin/host] in csf.conf is either incorrect, is not installed or is not executable

By | December 26, 2015

The following error may occur while reloading CSF (csf -r) :

*WARNING* Binary location for [HOST] [/usr/bin/host] in /etc/csf/csf.conf is either incorrect, is not installed or is not executable
*WARNING* Missing or incorrect binary locations will break csf and lfd functionality

In this particular case, CSF was installed on a CentOS 7 server and there wasn’t any “host” executable under /usr/bin.

To resolve this issue, just install the missing package which is provided by Bind Utilities (bind-utils) :

yum install bind-utils
