ipv6 ping problem

[StZ]

Hi,

after read and read and google and more google about it , i cant get the ipv6 pings working in zabbix... my config is the following :

- Zabbix 1.8.5
- fping and fping6 configured with -I option available.
- dualstack config, ipv4 and ipv6 configured on eth0
- ipv4 and ipv6 addresses configured as LISTEN IP on zabbix_server.conf

ping6 and fping6 works ok from the command line but with zabbix i alway get "not supported" using a domain name or the ipv6 address for the host, using icmpping[IPV6 ADDRESS] i get the same result.

and that is my big #fail with zabbix, and i really need to do ping to ipv6 adress...

Some ideas???

Help??

Please v,v


Thanks to all

Did you set the following parameter in your zabbix_server.conf ?

### 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

Hi,

Yes, the fping and fping6 location is present in my zabbix_server.conf:

FpingLocation=/usr/local/sbin/fping

Fping6Location=/usr/local/sbin/fping6

and

[root@zabbix1 sbin]# ls -al
total 3156
drwxr-xr-x  2 root root      4096 Jul 19 00:44 .

-rws--s---  1 root zabbix   61276 Jul 14 16:56 fping6

ps axu

Thanks for your help

Possible workaround

The problem with fping/fping6 ist that they are fed with the same temporary file created by zabbix. Example:

sh -c /usr/sbin/fping -q -C3 2>&1 </tmp/zabbix_server_9647.pinger; /usr/sbin/fping6 -q -C3 2>&1 </tmp/zabbix_server_9647.pinger

If the file contains IPv6 addresses, fping6 is fine, but if if the file contains IPv4 addresses or FQDN that do not resolve to IPv6 addresses, fping6 bails out.

My workaround is to have a wrapper around fping6 that filter IPv4 addresses.
I can now successfully monitor hosts that have IPv6 addresses :-)

In zabbix_server.conf, you have to specify the path to the script:

Fping6Location=/path/to/fping6.sh

and restart zabbix server

Hope this helps
