Zabbix 1.8.2 agent does not work when monitored Debian system has IPv6 enabeld

brandizzi asked:

We have a Zabbix Server 1.8.2 running on an Debian VM – installed from the repositories of Squeeze. Also, we are installing Zabbix 1.8.2 agents in various other VMs, most of them running Debian, installed through apt-get, too.

Once we installed the agent in the host and create the corresponding host in server, we cannot make the server collect info from the agent if the monitored host does support IPv6. If we disable IPv6 on the monitored host, the agent works well and the server monitors it flawlessly.

The question is: why does this happen? Is there another way to avoid this problem? There has some way of “disabling IPv6” out of Zabbix agent?

Thanks in advance!

My answer:


This was a bug in zabbix_agentd that was fixed in 1.8.5.

This will be available in wheezy. It’s been proposed for squeeze-backports, though nothing has happened so far.

If you can’t update, you can work around it by specifically setting the ListenIP directive to your exact IPv4 address, for example:

ListenIP=198.51.100.30
