Zabbix and Checkpoint Endpoint software incompatible

[lolek17]

Hi!

I installed zabbix agent on Windows XP and make two scripts to check status of VPN.

When I run a script on XP machine it always recive correct value (0 or 1), but when I use zabbix_get utility i get:
correct value or zabbix_get [62726]: Get value error: or blank

zabbix-agent log:

So no difference whatever it recived correct value or not.
zabbix-server log:

 38458:20140804:152533.038 Zabbix agent item "wm.ports" on host "Charon" failed: first network error, wait for 15 seconds

I attached a screenshot from wireshark.

Next I uninstalled Checkpoint Endpoint Security from my system and it starts working without problems, but I need this software so what should I now?

Sorry for my poor english.

You:
"Next I uninstalled Checkpoint Endpoint Security from my system and it starts working without problems"

And the software description:
"Firewall and Compliance Check: Stop unwanted traffic, prevent malware and block targeted attacks"

As for me it looks as the soft firewall was disrupting zabbix communication.

I have firewall set to "Off". Zabbix has problems when Checkpoint Endpoint service is running, no difference whether VPN is connected or not.

So as I stated before the Checkpoint Endpoint program has some firewall rules prohibiting communications between zabbix agent and server

There aren't any firewall rules, firewall is set to "Off".
