使用 powershell 脚本发送 SNMP 陷阱

Question

我正在尝试使用 powershell 脚本发送 SNMP 陷阱（它必须是 powershell 脚本，它将是运行在 windows 服务器上）。我有一个带有陷阱接收器的测试环境运行。

我一直在学习本教程http://www.activexperts.com/network-component/howto/snmpts/powershell10/，但我还没有开始工作。

下面是我的代码，脚本运行很好

$objSnmpTrapManager = new-object -comobject AxNetwork.DnsServer #create object
# Create a SnmpTrapOut instance
$objSnmpTrapManager = new-object -comobject AxNetwork.SnmpTrapManager
$objSnmpTrap     = new-object -comobject AxNetwork.SnmpTrap
$objSnmpObject   = new-object -comobject AxNetwork.SnmpObject
$objConstants    = new-object -comobject AxNetwork.NwConstants

# Initialize SNMP
$objSnmpTrapManager.Initialize()
$res = "Initialize, result: " + $objSnmpTrapManager.LastError + " (" + $objSnmpTrapManager.GetErrorDescription( $objSnmpTrapManager.LastError ) + ")"
Write-Host $res
If($objSnmpTrapManager.LastError -ne 0 )
{
  exit
}

# Get Host, community name and optionally a MIB file
$strHostName    = "*******"
$strCommunity   = "public"

# Set trap properties
$objSnmpTrap.Clear()
$objSnmpTrap.Host     = $strHostName
$objSnmpTrap.Community = $strCommunity
$objSnmpTrap.Port     = 80 #is this the port that my trap reciever is looking at? or should it be the default 162

# Add first variable to trap
$objSnmpObject.Clear()
$objSnmpObject.OID   = ".1.3.6.1.2.1.1.5.0"
$objSnmpObject.Type  = $objConstants.nwSNMP_TYPE_OCTETSTRING
$objSnmpObject.Value = "test"
$objSnmpTrap.AddObject($objSnmpObject)

# Send the trap.
$objSnmpTrapManager.Send($objSnmpTrap)
$res = "Send, result: " + $objSnmpTrapManager.LastError + " (" + $objSnmpTrapManager.GetErrorDescription($objSnmpTrapManager.LastError) + ")"
Write-Host $res

# Shutdown SNMP
$objSnmpTrapManager.Shutdown()
$res = "Shutdown, result: " + $objSnmpTrapManager.LastError + " (" + $objSnmpTrapManager.GetErrorDescription($objSnmpTrapManager.LastError) + ")"
Write-Host $res

一切都表明成功，我认为我的问题是定义发送陷阱的位置（如果有人能提供一个很棒的例子！）

有没有人愿意分享任何帮助或资源？

谢谢！

端口 ($objSnmpTrap.Port) 应该是 162，默认的 SNMP Trap 接收器 (或 trapsink) 端口 - 除非你明确地将它更改为端口 80您的测试环境：

# Get Host, community name and optionally a MIB file
$strHostName    = "receiver.test.environment.example"
$strCommunity   = "public"

# Set trap properties
$objSnmpTrap.Clear()
$objSnmpTrap.Host     = $strHostName
$objSnmpTrap.Community = $strCommunity
$objSnmpTrap.Port = 162

使用 powershell 脚本发送 SNMP 陷阱

Send SNMP trap with powershell script

powershell

snmp

snmp-trap
