VBScript Code to List SNMP MIB-II TCP and UDP Connections and Listening Ports

You can use any of the VBScript programs below in ActiveXperts Network Monitor. Click here for an explanation about how to include scripts in ActiveXperts Network Monitor.

Example(s)

strTargetSnmpDevice = "192.168.0.1"
 
Set objWmiLocator = CreateObject("WbemScripting.SWbemLocator")
Set objWmiServices = objWmiLocator.ConnectServer("", "root\snmp\localhost")
 
Set objWmiNamedValueSet = CreateObject("WbemScripting.SWbemNamedValueSet")
objWmiNamedValueSet.Add "AgentAddress", strTargetSnmpDevice
objWmiNamedValueSet.Add "AgentReadCommunityName", "public"
 
Set colTcpConnTable = _
    objWmiServices.InstancesOf("SNMP_RFC1213_MIB_tcpConnTable", , _
        objWmiNamedValueSet)
 
Set colUdpTable = _
    objWmiServices.InstancesOf("SNMP_RFC1213_MIB_udpTable", , _
        objWmiNamedValueSet)
 
 
WScript.Echo "TCP Connections and Listening Ports" & vbCrLf & _
    "-----------------------------------"
 
For Each objTcpConn In colTcpConnTable
    WScript.Echo objTcpConn.tcpConnLocalAddress & ":"    & _
        objTcpConn.tcpConnLocalPort    & " => " & _
            objTcpConn.tcpConnRemAddress   & ":"    & _
                objTcpConn.tcpConnRemPort      & " "    & _
                    "[State: " & objTcpConn.tcpConnState & "]"
Next
 
WScript.Echo vbCrLf & "UDP Ports" & vbCrLf & "---------"
 
For Each objUdp In colUdpTable
    WScript.Echo objUdp.udpLocalAddress & ":" & objUdp.UdpLocalPort
