server does not have snmpwalk permission on the target host

[seaward1983]

nagios ver 5.6.8
RHEL 6.10

Target - Windows 2012 R2
SNMP authentication enabled/configured
Firewall UDP confirmed inbound and outbound rules
Snmpwalk command from Nagios host to target "no response from [servername]"

It's got to be something I'm missing, right?

Let's make sure that we can get to the Windows server.

Code: Select all

nmap -sU <remoteIPaddress> -p 161,162

If possible, it may be worth temporarily turning off the Windows firewall, and running the snmpwalk just to test.

Here's the results -

Starting Nmap 6.47 ( http://nmap.org ) at 2019-12-10 16:02 CST
Nmap scan report for 638579-DWASQL01.rsp.medecision.com (172.21.57.66)

That output indicates that the firewall ports are correctly open.

This sounds like a security issue. What type of SNMP security did you define on the windows server?

Here is an example command you can execute on your Nagios XI server in a terminal session:

Code: Select all

snmpwalk -v 2c -c public xxx.xxx.xxx.xxx -m all 1.3.6.1.4.1

This example uses SNMP v2c security. Replace public with the name of the community you defined on the server.
Replace xxx.xxx.xxx.xxx with the address of the server.

What output do you get?

Okay - it's resolved. This server vmotioned to another hypervisor that didn't have a VLAN configured correctly. I now can do a SNMPwalk and get all sorts of funness.

Excellent! Glad you were able to get it resolved. Also thank you for posting the result back here. I'll go ahead and close this.
