Cacti Unable SNMPWalk Windows Storage Server Standard

[dchochan]

Hi All,

I had installed Cacti version 0.8.8b+dfsg-8+deb8u6 and spine version 0.8.8b-1 on Debian 8 which is container from Proxmox VE.
But somehow only machine with Windows Storage Server Standard edition had problem with SNMP connection while other machine do not have this issue.

I had disabled firewall to make sure no issue with firewall for both Windows Storage Server & Cacti Server.
Also had tried SNMPwalk from my desktop PC and no problem (testing it with Solarwind Realtime Bandwith Monitor no problem).
I am sure no problem with Windows Server Storage SNMP configuration from service.exe.

Following test result from SNMPwalk:

root@nms:~# snmpwalk -v 2c -c rubycon 192.168.61.4 .1.3.6.1.2.1.1.1.0
Timeout: No Response from 192.168.61.4

Following from Cacti log:

01/12/2017 03:24:32 PM - CMDPHP: Poller[0] WARNING: SNMP Get Timeout for Host:'192.168.61.4', and OID:'.1.3.6.1.2.1.1.1.0'
01/12/2017 03:23:42 PM - CMDPHP: Poller[0] WARNING: SNMP Get Timeout for Host:'192.168.61.5', and OID:'.1.3.6.1.2.1.1.1.0'

Any help would be really appreciate.
Thank you very much.

Anyone who had face same problem here?

This issue could be any of the following:

1) You have connectivity issues between the Cacti server and the Windows Storage Server. You mentioned that you disabled the firewall, are you sure the SNMP packets are reaching the storage server? Have you done a packet capture to verify this?
2) Are you absolutely sure that you have the right community? If you have the wrong community, the server will not reply.
3) Are you absolutely sure that the IP address of the Cacti server is allowed to query SNMP on the server? check the properties of the SNMP service to verify that either all IPs are allowed to query SNMP or that the IP address of your cacti server is.


These are generally the only thing that would cause a timeout.

Hi Sir,

Thank you very much for the reply. I had found the solution a month ago which is related to firewall issue. I though all of our server had firewall turn off using Domain Network profile because we activated it from Active Directory Server GPO. But it turn out that Windows Server Storage Edition do not have Domain Network profile as it firewall template and it using Public Network profile which is block port 161 and 162 inbound and outbound.

I have opened the port 161 and 162 for those server and the problem solve. It is so silly I am not knowing that Windows Server Storage Edition really different with Windows Server 2008 R2 because I think it same.
