Re: wbem-wmi hp sim port

To answer David's question, the networking team did open port 5989. I configured the WMI Mapper in SIM.

Below was the log from the firewall.

10.46.200.82 is the managed node behind the firewall.

192.168.67.214 is the SIM server.

Re: wbem-wmi hp sim port

OK finally got some answers.
Windows servers will always use WMI (unless you configure SNMP).

The WBEM "Agent / Providers" are not WBEM, they are an extension of the existing WMI CIM Schema.

If they would have just stated that they are extending the WMI CIM Schema, this would have saved allot of time and headachs.

The only way to get this to go through a single port is to change the setting on the windows server to forward WMI Events (NOT WBEM Events, BECAUSE IT DOESN'T EXIST ON WINDOWS) events to the WMI Mapper, so it can turn it into the WBEM protocol that the SIM server understands.

Please people at HP, pull your heads out of your wikipeda, and fix your documentation calling WMI, WBEM, when its clearly NOT WBEM, its WMI.

Re: wbem-wmi hp sim port

Hi Jeremy,

How do we configure Windows to forward WMI events to the WMI Mapper? Do you have any documentation or know how in doing so?

Thanks,

Re: wbem-wmi hp sim port

I haven't gotten that far yet, here is one doc
http://msdn.microsoft.com/en-us/library/bb219447%28v=vs.85%29.aspx

I believe its going to require port 135 (DCOM) and another port for actual communication.


Ill let you know when i finish testing.

Re: wbem-wmi hp sim port

The model that is used for WMI Indications is the opposite of that for SNMP (where you configure the trap destination on the target's SNMP service). WMI Indications use a subscription model whereby your management application 'subscribes' to the device. This is done through 'Manage Communications' in HP SIM. When you do that, it will establish the path through the requisite WMI Mapper to route communications to the HP SIM CMS.

Re: wbem-wmi hp sim port

its not looking good.

if this is correct it means HP's secure sytem requires you to degrade security by opening a crapload of ports.

Re: wbem-wmi hp sim port

I think the commands in "Setting Up a Fixed Port for WMI" document is for Windows firewall. We don't use Windows firewall in our Windows Server 2003 servers and have have disabled it so it doesn't apply here. The Windows servers are behind the Cisco's firewalls.

All we do here is to refer to the HP documentation, and seems like nobody has gotten this to work yet. I wonder if someone from HP can actually do some testing, confirm this actually works and document it instead of just refer to the documentation all the time? Thanks.

Re: wbem-wmi hp sim port

Do we have a definitive solution to get WBEM functioning through a non-windows firewall? I'm looking to solution this now. Thanks in advance.

Re: wbem-wmi hp sim port

That's correct. It depends where is the WMI Mapper is installed.

 

1) If the WMI Mapper is installed on the tagrget node (managed node), then opening of the above ports in the firewall will solve the issue.

 

2) If WMI Mapper acts as an proxy (Remote) or installed on the CMS the communication between the CMS and Target node will be on Dynamic Ports (as that is COM-DCOM call).

if it helped, award me Kudos or Points. Thanks :)
