WMI, Plugin Timed out and ports

[Francesco]

Hi all,
we obtain a "Plugin Timed out (15 sec)" using check_wmi_plus.pl to monitoring some windows machines.

I can not ask to open all the traffic, so I'm collecting all information about WMI and ports

• https://assets.nagios.com/downloads/nag ... ios-XI.pdf
• https://support.nagios.com/kb/article/n ... i-122.html
• https://support.nagios.com/kb/article/n ... g-579.html

Can you please confirm me that WMI start over 135 port, and later continue over random (DCOM) port?

In the PDF is explained how to fix WMI port on win2003 server. There is any doc, written by nagios Team, for newer Microsoft OS?

In the mean time I found this small MSDN doc
https://msdn.microsoft.com/en-us/librar ... s.85).aspx

many thanks,

The following document is the latest document but there is not any information on setting a fixed port.

TCP port 135 is the standard port for RPC which WMI uses to connect to the Windows server.

Typically the higher ports are used to transfer the WMI data and vary on which operating system is running and the document does talk about how to open them up.
