A simple shell script that will restore the permissions to fping & fping6 required by Zabbix following an update or other system change. I use this as part of a daily cron. NOTE: this is designed for RHEL/CentOS, and assumes that you are running Zabbix from a group named "zabbix".

fpingperm.sh

#!/bin/bash

x=0
y=0

if [ -e /usr/sbin/fping ]
  then
    if [ `stat -c %a:%G /usr/sbin/fping` == "6710:zabbix" ]
      then
        echo "Sticky bit assigned and owner set"
      else
        echo "Permissions incorrect for fping, fixing"
        chown root:zabbix /usr/sbin/fping
        chmod 710 /usr/sbin/fping
        chmod ug+s /usr/sbin/fping
    fi
  else
    echo "fping does not exist in /usr/sbin/"
    x=1
fi

if [ -e /usr/sbin/fping6 ]
  then
    if [ `stat -c %a:%G /usr/sbin/fping6` == "6710:zabbix" ]
      then
        echo "Sticky bit assigned and owner set"
      else
        echo "Permissions incorrect for fping6, fixing"
        chown root:zabbix /usr/sbin/fping6
        chmod 710 /usr/sbin/fping6
        chmod ug+s /usr/sbin/fping6
    fi
  else
    echo "fping6 does not exist in /usr/sbin/"
    y=1
fi

if [ y -eq 1 ]
  then
    if [ x -eq 1 ]
      then
        exit 2
      else
        exit 1
    fi
fi

exit 0
