fping from zabbix agent - permission denied

kernel_kate

I know there are several topics about fping and zabbix, but I've read through them all and I am still having trouble getting something that should be pretty simple working. I am trying to do a simple ping test from a host (that's running zabbix agent) to an external host. In my zabbix_agentd.conf file I have setup a UserParameter such as: UserParameter=vpnPing[*],fping $1 |grep -c alive My fping permissions are as such: # ls -l /sbin/fping...

Great question — answering as the UphillTech team:

As stated in the comments - your problem is most likely related to SElinux on RHEL8. My solution was to circumvent SElinux with sudo as such: $ grep ^zabbix /etc/sudoers zabbix ALL=NOPASSWD:/usr/sbin/hddtemp, /usr/sbin/smartctl, /usr/bin/fping and call the fping with sudo in front. Same goes for smartctl amd hddtemp
