Sorry, this binaries don't have suid set. I guess you did change that on
your own. Maybe you should have a look into

plugins needing root privilege

the check_dhcp, check_icmp and maybe others plugins require root
privileges to
run, because of the low-level packet mangling that they perform.
but, in the interest of the "safe default", these plugins will not
be installed with the suid bit set.  there are two recommended ways
about overriding this on your system:

- set the suid bit with dpkg-statoverride:

# dpkg-statoverride --update --add root nagios 4750 $plugin

where $plugin is the specific plugin you want to grant such privileges.

- use sudo to grant the permissions and modify your plugin config

of these two, the first is recommended because it's the simplest and
has the same effect as the second.

The default configuration is to use check_ping for the host check.
