zabbix-agent 2.2 - no route to host

[eljibe]

Hi all,

I have successfully installed the zabbix server on a CentOS 6.5 virtual machine (through virtualbox). I added the zabbix repositories, disabled selinux (ok, it wasn't done, but is now)... Things look good and I have a nice web interface telling me everything is fine. So far, so good.
So now I set up a new virtual machine on which I want to install the agent. I went through the same process, disabled iptables and selinux, added the repositories, specified my first machine in the agent config file as a server (I gave it the ip address).
But when I try to add an item, things don't seem to work.
I keep getting the [113] no route to host in the web interface.
Plus when I try to telnet the agent on port 10050 I get "Connection closed by foreign host." instantaneously.
Any idea (I suck at networking, so do not hesitate to point me where I can look at if this is a network problem) ?
Both VMs use bridged network interfaces, and can communicate with the internet.

Could you ping second VM from first one and vice verse?

Could you use telnet connection?

telnet {ip_of_second_vm} 10050

Yes, ping worked, telnet didn't, for a reason I don't understand.
But I ended up solving my problem, by editing the agentd configuration file and setting the Server and ServerActive keys, filling them up with the IP address of the zabbix server and settinc the zabbix_can_network to on. I must say I don't know what fixed the issue though.

settinc the zabbix_can_network to on.

This setting fixed your problem.
You just allow zabbix to work through Firewall.

Adding both settings - Server= and ServerActive= it's not important. Except you are going to mix "Zabbix Agent" and "Zabbix Agent(active)" checks type for this particular host.

Keyword "Server=" works only for "Zabbix Agent"
Keyword "ServerActive=" works only for "Zabbix Agent(active)"

Anyway - you solved your problem without any advice. Good for you!
