How to monitor two machines behind the firewall/NAT

[kanour]

Just would like to ask how to monitor more machines which are behind firewall/NAT?

Is there any best option?

[DiedX]

Forward 2 ports, and enable zabbix-client on an other port?

Forward 1 port, and let 1 client check another?

[kanour]

OK. I understand to forward 2 ports 10052 and 10053 and setup each agentd to listen on these ports.

I don't understand to the second option? Can you explain?

[DiedX]

yup!

The latter option is to connect to the first client, and let him check the services on the internal network. The problem with this option is that you cannot check all services.

I advice to use the first option!

[kanour]

I have to explain why I was asking.

I actualy setup the first option, but it did not work. It still does not work.

I have server (Debian) running zabbix_server_1.1beta9
-----------------
Internet
-------------------
I have firewall (Debian) running zabbix_agentd_1.1beta9 (port 10050)
I have workstation (Win XP) behind firewall running zabbixagentdW32_1.1beta3 (port 10052)

On the firewall I have DNAT to workstation (Win XP) on port 10052
On the server I have setup port 10052 for that Win XP host
Firewall itself accepts port 10050

I know that the setup is definitely OK, but win XP agent does not want to work.
Firewall works without problem.

As I received reply that other version of agent and server should work I am lost.

Would anyone have any suggestion?

The error which is displayd in host is:
Not available Got empty string from [als04.allsupp.ath.cx] IP [] Parameter [agent.version]

[kanour]

Also error:
Not available Got empty string from [als04.allsupp.ath.cx] IP [] Parameter [agent.ping]

I would suggest to use active checks. In this case the agent will be active side, and all connections will be made the agents not by ZABBIX server.

[kanour]

So in that case agent on winxp does not work. I still can not get anything.

In the case of active checks, how should be host named on the zabbix server? Or how the server recognize that it is the right host?

[erisan500]

I'll give you a cofiguration example:


Zabbix server ip 10.0.0.10
has host My_WinXP_Box with IP 10.0.20.20
-------------------------
internet
-------------------------
WinXP Client with ip 10.0.20.20 and the following zabbix_agentd.conf:

Server=10.0.0.10
Hostname=My_WinXP_Box


Your host on the zabbix server should also be called My_WinXP_Box and change the checks to Active checks. Now the monitored hosts will send their data to the zabbix server.

Offcourse the ip's should be changed to your public ip's.

So I tried to install zabbix_server on the local net. The windows agent does not probably work at all. Even on local net.

Is there any testing procedure?
The service is running the configuration file is:

Any suggestions?

[kanour]

Does anything has to be installed except the agentd on win xp machine?

[erisan500]

replace the content from your zabbix_agentd.conf file with this:

Server=alssrv01
Hostname=als04
LogFile=C:\zabbix_agentd.log

Make sure if you use hostnames they resolve correctly. I suggest to use fixed ip addresses for testing and when everything works ok you can move to hostnames.

After you made the changes to the conf file, restart the zabbix service.

[kanour]

Still same.
Not available Connection reset by peer

Where could be the mistake? Is there any prerequisit prior installation of win32 agent?

[erisan500]

Please post the locations of zabbixw32.exe and zabbix_agentd.conf and what command you used to install the agent.
