fping: address family for hostname not supported

[varnav]

Hello!

I'm getting this error "fping: address family for hostname not supported" if using ICMP ping template.

Zabbix 3.0.0 on CentOS 7.2

[varnav]

I set Fping6 option to empty in config file.

Now I'm getting another problem: fping failed (null): can't create socket (must run as root?): Permission denied

[varnav]

Looks like the solution is to run commands in the following order:

chown root:zabbix /usr/sbin/fping
chmod 4710 /usr/sbin/fping
chmod ug+s /usr/sbin/fping

Docs do not mention last command.

You can test it then by running:

su - zabbix -s /bin/bash
fping 8.8.8.8

it has to return: 8.8.8.8 is alive
