fping failed: "/usr/sbin/fping6: can't create raw socket (must run as root?) : Operat

[carlitos_30]

Hello.

I was looking for a NMS and Google lead me to Zabbix. I downloaded the VM image.

When I try to create a ping item I get the following message:

"fping failed: "/usr/sbin/fping6: can't create raw socket (must run as root?) : Operation not permitted"

I applied the commands:

chown root:zabbix /usr/sbin/fping
chmod 4710 /usr/sbin/fping

chown root:zabbix /usr/sbin/fping6
chmod 4710 /usr/sbin/fping6

then reboot the VM.

The damned thing still doesn't work.

It's hard to understand a supossed professional level software comes with this kind of details.

"Focus in the user" I read in someplace.

i experienced the same thing. I think what may have fixed it is uncommenting the 2 lines:

# Mandatory: no
# Default:
FpingLocation=/usr/sbin/fping

### 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

located in the zabbix-server.conf in the /etc/zabbix folder

and then restarting the server...

Solved

Thank you very much scdickey. Your solution worked to me. I think this post should be sticked.

Thanks again!

Hmm. Curious.

I just deployed the OVF template for Zabbix and was having this same exact issue.

I did the chown/chmod commands as per the manual and it didn't fix anything. I came across this and did the fix, but now I'm getting:

" At least one of '/usr/sbin/fping', '/usr/sbin/fping6' must exist. Both are missing in the system. "

Any thoughts?

Those files are DEFINITELY there. I just tried to use them:

> sudo /usr/sbin/fping anip
>> anip is alive

Any ideas?

Can you show the output of these commands?

# which fping
/usr/sbin/fping

# ls -l /usr/sbin/fping
-rws--x---. 1 root zabbix 37079 Nov 10 2010 /usr/sbin/fping

And then show the section of your zabbix_server.conf file that shows the fping parameter:

# Mandatory: no
# Default:
FpingLocation=/usr/sbin/fping

[msantangelo]

I actually figured it out this afternoon! On the 2.4 OVF, the server instance runs as user zabbixs, in group zabbixs. The fping and fping6 in /usr/sbin had permissions granted to zabbix. This was fixed by either changing fping and fping6 group to zabbixs (favorable) or adding zabbixs to group zabbix (not so favorable)

In the 2.2 OVF, the user zabbix is not in group zabbix, which is fixed with usermod -a G zabbix zabbix.

Weird.

Can you show the output of these commands?

# which fping
/usr/sbin/fping

# ls -l /usr/sbin/fping
-rws--x---. 1 root zabbix 37079 Nov 10 2010 /usr/sbin/fping

And then show the section of your zabbix_server.conf file that shows the fping parameter:

# Mandatory: no
# Default:
FpingLocation=/usr/sbin/fping

At least one of '/usr/sbin/fping', '/usr/sbin/fping6' must exist. Both are missing

msantangelo,

That fixed it for me to. The command actually has a "-" before the G:

usermod -a -G zabbix zabbix

uncommented FpingLocation and FpingLocation, and restarting the service returns an error and could not start zabbix agent service.
Any ideas?

[msantangelo]

What's your zabbix error log show? Maybe you entered some text elsewhere in the file that is gumming up the works.

Uncommenting those lines doesn't do anything, as those are the default settings. Zabbix will use the defaults regardless of being commented or not.

The only difference would be if you changed something on that line and uncommented it.

Thanks tchjts1.
Manage to get fping trigger working, without uncommented any lines in conf. file.
Here's another thread that followed and helps.

chown root:zabbix /usr/bin/fping

Another thing to consider:
Did you disable support for IPV 6 on your server? Thank you all for your help - this thread lead me to success on that note.

[root@~]# grep fping6 /etc/zabbix/zabbix_server.conf
# Location of fping6.
# Make sure that fping6 binary has root ownership and SUID flag set.
#ORIG## Fping6Location=/usr/sbin/fping6
#NEXT LINE FAKED OUT BECAUSE IPV6 IS DISABLED ON THIS RHEL 8 SYSTEM##Fping6Location=/usr/sbin/fping6
Fping6Location=/usr/sbin/fping
[root@~]#

[sajihome]

The below Steps worked for me
Give Permission
usermod -a -G zabbix zabbix
Edit in Zabbix Config
FpingLocation=/usr/sbin/fping
Fping6Location=/usr/sbin/fping

Enable IPv6 in Ubuntu

Good luck
