fping6: can't create raw socket (must run as root?) : Address family not supported

[akarim]

I understand that it is a recurring theme, and common in the forum, as well as in some proposed solutions.

But I want to put another approach.

After reading several posts that told me about the permissions, I checked them and I think they are correct and that is not the issue

ls -lisah / usr / sbin / fpi *
134345224 52K -rwsr-xr-x 1 root root 52K Aug 5 2019 / usr / sbin / fping
134345226 52K -rwsr-xr-x 1 root root 52K Aug 5 2019 / usr / sbin / fping6

The question is that in my system there is NO IPV6 (I totally deactivate it) and I think that is the question, and I don't know how to tell Zabbix not to use fping6

Here the same problem with LTS 5.0 and ubuntu 20.04.

Solved by:

• Comment /etc/zabbix/zabbix_server.conf line:

### Option: Fping6Location # Location of fping6. # Make sure that fping6 binary has root ownership and SUID flag set. # Make empty if your fping utility is capable to process IPv6 addresses. # # Mandatory: no # Default: # Fping6Location=/usr/sbin/fping6

• Apply permissions:

# chown root:zabbix /usr/bin/fping
# chmod 4710 /usr/bin/fping

• Restart zabbix server:

# systemctl restart zabbix-server
