用javascript代码实现对客户端ip地址的获取

    昨天台北那边的垃圾们丢给我一个任务，由于ACL页面的设置，需要对客户端机的ip地址进行自动获得，以便进行ip的过滤设定。真受不了什么都要我们做，我都不明白他们台北那帮人都在忙什么，社交，关系，走访客户，郁闷，为什么总是不好解决的东西就会丢过来。没办法谁让自己是一个打工仔呢，只能任由别人来使唤剥削喽。我相信总有一天我非把他们都踩在地下不行，什么两岸同胞扯淡，台湾人压根就没瞧得起大陆人，歧视问题很严重。不过没办法大陆有钱人不少，可是我不是唷只能发发牢骚了。下面转入整体，我从网上搜寻了半天找到了一个用javascript来实现的代码，代码比较简单，但是必须用到了两个ActiveX控件，这两个控件不用去下载，Microsoft的系统中就有不过是要去加载，我看了资料发现这是一个很多功能的控件，比较有用处，我通过msdn在线查找找到英文下的帮助文档，顺便贴出来大家共享吧反正都是网上共享资源，只是如果你看到了别忘了给俺留句言，礼尚往来，来而非去，君子也嘛。这里我只是贴出了Win32_NetworkAdapterConfiguration的，好像还有几個，不过需要你哥们自己查了，时间宝贵呢我就不查了，如果查到别的别忘了贴出来，共享时代你我他！！！

Win32_NetworkAdapterConfiguration Class

 

The Win32_NetworkAdapterConfiguration WMI class represents the attributes and behaviors of a network adapter. This class includes extra properties and methods that support the management of the TCP/IP and Internetwork Packet Exchange (IPX) protocols that are independent from the network adapter.

The following syntax is simplified from Managed Object Format (MOF) code and includes all of the inherited properties. Properties are listed in alphabetic order, not MOF order.

Properties

The Win32_NetworkAdapterConfiguration class defines the following properties.

ArpAlwaysSourceRoute

Data type: boolean
Access type: Read-only

 

If TRUE, TCP/IP transmits Address Resolution Protocol (ARP) queries with source routing enabled on Token Ring networks. By default (FALSE), ARP first queries without source routing, and then retries with source routing enabled if no reply is received. Source routing allows the routing of network packets across different types of networks.

 

ArpUseEtherSNAP

Data type: boolean
Access type: Read-only

 

If TRUE, Ethernet packets follow the IEEE 802.3 Sub-Network Access Protocol (SNAP) encoding. Setting this parameter to 1 forces TCP/IP to transmit Ethernet packets by using 802.3 SNAP encoding. By default (FALSE), the stack transmits packets in DIX Ethernet format. Windows 2000 and Windows NT systems can receive both formats.

 

Caption

Data type: string
Access type: Read-only

 

Description of the CIM_Setting object—a one-line string. This property is inherited from CIM_Setting.

DatabasePath

Access type: Read-only

 

Valid Windows file path to standard Internet database files (HOSTS, LMHOSTS, NETWORKS, and PROTOCOLS). The file path is used by the Windows Sockets interface. This property is only available on computer systems running Windows 2000 and Windows NT.

DeadGWDetectEnabled

Data type: boolean

 

If TRUE, dead gateway detection occurs. With this feature enabled, Transmission Control Protocol (TCP) asks Internet Protocol (IP) to change to a backup gateway if it retransmits a segment several times without receiving a response.

DefaultIPGateway

Data type: string array
Access type: Read-only

 

Array of IP addresses of default gateways that the computer system uses.

Example: "192.168.12.1 192.168.46.1"

 

DefaultTOS

Access type: Read-only

 

Default Type Of Service (TOS) value set in the header of outgoing IP packets. Request for Comments (RFC) 791 defines the values. Default: 0 (zero), Valid Range: 0 - 255.

DefaultTTL

Data type: uint8
Access type: Read-only

 

Default Time To Live (TTL) value set in the header of outgoing IP packets. The TTL specifies the number of routers an IP packet can pass through to reach its destination before being discarded. Each router decrements by one the TTL count of a packet as it passes through and discards the packets—if the TTL is 0 (zero). Default: 32, Valid Range: 1 - 255.

Description

Example: "microsoft.com"

 

DNSDomainSuffixSearchOrder

Data type: string array
Access type: Read-only

 

Array of DNS domain suffixes to be appended to the end of host names during name resolution. When attempting to resolve a fully-qualified domain name (FQDN) from a host-only name, the system will first append the local domain name. If this is not successful, the system will use the domain suffix list to create additional FQDNs in the order listed and query DNS servers for each.

Example: "samples.microsoft.com example.microsoft.com"

DNSEnabledForWINSResolution

Data type: boolean
Access type: Read-only

 

If TRUE, the Domain Name System (DNS) is enabled for name resolution over Windows Internet Naming Service (WINS) resolution. If the name cannot be resolved using DNS, the name request is forwarded to WINS for resolution.

DNSHostName

Data type: string
Access type: Read-only

 

Host name used to identify the local computer for authentication by some utilities. Other TCP/IP-based utilities can use this value to acquire the name of the local computer. Host names are stored on DNS servers in a table that maps names to IP addresses for use by DNS. The name can be any combination of the letters A through Z, the numerals 0 through 9, and the hyphen (-), plus the period (.) character used as a separator. By default, this value is the Microsoft networking computer name, but the network administrator can assign another host name without affecting the computer name.

Example: "corpdns"

DNSServerSearchOrder

ForwardBufferMemory

Data type: uint32
Access type: Read-only
Qualifiers: Units(Bytes)

 

Memory allocated by IP to store packet data in the router packet queue. When this buffer space is filled, the router begins discarding packets at random from its queue. Packet queue data buffers are 256 bytes in length, so the value of this parameter should be a multiple of 256. Multiple buffers are chained together for larger packets. The IP header for a packet is stored separately. This parameter is ignored and no buffers are allocated if the IP router is not enabled. The buffer size can range from the network MTU to a value smaller than 0xFFFFFFFF. Default: 74240 (fifty 1480-byte packets, rounded to a multiple of 256).

 

FullDNSRegistrationEnabled

IPEnabled

Data type: boolean
Access type: Read-only

 

If TRUE, TCP/IP is bound and enabled on this network adapter.

IPFilterSecurityEnabled

Data type: boolean
Access type: Read-only

 

If TRUE, IP port security is enabled globally across all IP-bound network adapters and the security values associated with individual network adapters are in effect. This property is used in conjunction with IPSecPermitTCPPorts, IPSecPermitUDPPorts, and IPSecPermitIPProtocols. If FALSE, IP filter security is disabled across all network adapters and allows all port and protocol traffic to flow unfiltered.

IPPortSecurityEnabled

Data type: boolean
Access type: Read-only
Qualifiers: Deprecated

 

If TRUE, IP port security is enabled globally across all IP-bound network adapters. This property is obsolete. In place of this property, you should use IPFilterSecurityEnabled.

IPSecPermitIPProtocols

Data type: string array
Access type: Read-only

 

Array of the protocols permitted to run over the IP. The list of protocols is defined using the EnableIPSec method. The list will either be empty or contain numeric values. A numeric value of 0 (zero) indicates access permission is granted for all protocols. An empty string indicates that no protocols are permitted to run when IPFilterSecurityEnabled is TRUE.

IPSecPermitTCPPorts

Windows Server 2003, Windows XP, Windows 2000, and Windows NT 4.0:  Array of characters that uniquely identifies a frame or network adapter combination on the computer system. The NetWare Link (NWLink) IPX/SPX-compatible transport in Windows 2000 and Windows NT 4.0 and later use two distinctly different types of network numbers. This number is sometimes referred to as the external network number. It must be unique for each network segment. The order in this string list will correspond item-for-item with the elements in the IPXFrameType property.

IPXVirtualNetNumber

Data type: string
Access type: Read-only

Windows Server 2003, Windows XP, Windows 2000, and Windows NT 4.0:  Unique identifier of the computer system on the network. It is represented in the form of an eight-character hexadecimal digit. Windows 2000 and Windows NT use the virtual network number (also known as an internal network number) for internal routing.

KeepAliveInterval

Data type: uint32
Access type: Read-only
Qualifiers: Units(Milliseconds)

 

Interval separating Keep Alive Retransmissions until a response is received. After a response is received, the delay until the next Keep Alive Transmission is again controlled by the value of KeepAliveTime. The connection will be aborted after the number of retransmissions specified by TcpMaxDataRetransmissions have gone unanswered. Default: 1000, Valid Range: 1 - 0xFFFFFFFF.

KeepAliveTime

Data type: uint32
Access type: Read-only
Qualifiers: Units(Milliseconds)

 

The KeepAliveTime property indicates how often the TCP attempts to verify that an idle connection is still intact by sending a Keep Alive Packet. A remote system that is reachable will acknowledge the keep alive transmission. Keep Alive packets are not sent by default. This feature may be enabled in a connection by an application. Default: 7,200,000 (two hours).

MACAddress

Data type: string
Access type: Read-only

 

Media Access Control (MAC) address of the network adapter. A MAC address is assigned by the manufacturer to uniquely identify the network adapter.

Example: "00:80:C7:8F:6C:96"

MTU

Data type: uint32
Access type: Read-only
Qualifiers: Units(Bytes)

 

Overrides the default Maximum Transmission Unit (MTU) for a network interface. The MTU is the maximum packet size (including the transport header) that the transport will transmit over the underlying network. The IP datagram can span multiple packets. The range of this value spans the minimum packet size (68) to the MTU supported by the underlying network.

NumForwardPackets

Data type: uint32
Access type: Read-only

 

Number of IP packet headers allocated for the router packet queue. When all headers are in use, the router will begin to discard packets from the queue at random. This value should be at least as large as the ForwardBufferMemory value divided by the maximum IP data size of the networks connected to the router. It should be no larger than the ForwardBufferMemory value divided by 256, since at least 256 bytes of forward buffer memory are used for each packet. The optimal number of forward packets for a given ForwardBufferMemory size depends on the type of traffic on the network. It will be somewhere between these two values. If the router is not enabled, this parameter is ignored and no headers are allocated. Default: 50, Valid Range: 1 - 0xFFFFFFFE.

PMTUBHDetectEnabled

Data type: boolean
Access type: Read-only

 

If TRUE, detection of black hole routers occurs while TCP discovers the path of the Maximum Transmission Unit. A black hole router does not return ICMP Destination Unreachable messages when it needs to fragment an IP datagram with the Don't Fragment bit set. TCP depends on receiving these messages to perform Path MTU Discovery. With this feature enabled, TCP will try to send segments without the Don't Fragment bit set if several retransmissions of a segment go unacknowledged. If the segment is acknowledged as a result, the MSS will be decreased and the Don't Fragment bit will be set in future packets on the connection. Enabling black hole detection increases the maximum number of retransmissions performed for a given segment. The default value of this property is FALSE.

PMTUDiscoveryEnabled

Data type: boolean
Access type: Read-only

 

If TRUE, the Maximum Transmission Unit (MTU) path is discovered over the path to a remote host. By discovering the MTU path and limiting TCP segments to this size, TCP can eliminate fragmentation at routers along the path that connect networks with different MTUs. Fragmentation adversely affects TCP throughput and network congestion. Setting this parameter to FALSE causes an MTU of 576 bytes to be used for all connections that are not to machines on the local subnet. The default is TRUE.

ServiceName

Data type: string
Access type: Read-only

 

Service name of the network adapter. This name is usually shorter than the full product name.

Example: "Elnkii"

SettingID

Data type: string
Access type: Read-only

 

Identifier by which the CIM_Setting object is known. This property is inherited from CIM_Setting.

TcpipNetbiosOptions

Data type: uint32
Access type: Read-only

 

Bitmap of the possible settings related to NetBIOS over TCP/IP.

Windows 2000 and Windows NT 4.0:  This property is not available.

Values are identified in the following table. Value (Dec/Hex) Meaning

EnableNetbios

2 0x2

DisableNetbios

TcpMaxConnectRetransmissions

Data type: uint32
Access type: Read-only

 

Number of times TCP attempts to retransmit a Connect Request before terminating the connection. The initial retransmission timeout is 3 seconds. The retransmission timeout doubles for each attempt. Default: 3, Valid Range: 0 - 0xFFFFFFFF.

TcpMaxDataRetransmissions

Data type: uint32
Access type: Read-only

 

Number of times TCP retransmits an individual data segment (nonconnect segment) before terminating the connection. The retransmission timeout doubles with each successive retransmission on a connection. Default: 5, Valid Range: 0 - 0xFFFFFFFF.

TcpNumConnections

Data type: uint32
Access type: Read-only

 

Maximum number of connections that TCP can have open simultaneously. Default: 0xFFFFFE, Valid Range: 0 - 0xFFFFFE.

TcpUseRFC1122UrgentPointer

Data type: boolean
Access type: Read-only

 

If TRUE, TCP uses the RFC 1122 specification for urgent data. If FALSE (default), TCP uses the mode used by Berkeley Software Design (BSD) derived systems. The two mechanisms interpret the urgent pointer differently and are not interoperable. The default value is TRUE.

TcpWindowSize

Data type: uint16
Access type: Read-only
Qualifiers: Units(Bytes)

 

Maximum TCP Receive Window size offered by the system. The Receive Window specifies the number of bytes a sender may transmit without receiving an acknowledgment. In general, larger receiving windows will improve performance over high-delay and high-bandwidth networks. For efficiency, the receiving window should be an even multiple of the TCP Maximum Segment Size (MSS). Default: Four times the maximum TCP data size or an even multiple of TCP data size rounded up to the nearest multiple of 8192. Ethernet networks default to 8760. Valid range: 0 - 65535.

WINSEnableLMHostsLookup

Data type: boolean
Access type: Read-only

 

If TRUE, local lookup files are used. Lookup files will contain a map of IP addresses to host names. If they exist on the local system, they will be found in %SystemRoot%/system32/drivers/etc.

WINSHostLookupFile

Data type: string
Access type: Read-only

 

Path to a WINS lookup file on the local system. This file will contain a map of IP addresses to host names. If the file specified in this property is found, it will be copied to the %SystemRoot%/system32/drivers/etc folder of the local system. Valid only if the WINSEnableLMHostsLookup property is TRUE.

WINSPrimaryServer

Data type: string
Access type: Read-only

 

IP address for the primary WINS server.

WINSScopeID

Data type: string
Access type: Read-only

 

Value appended to the end of the NetBIOS name that isolates a group of computer systems communicating with only each other. It is used for all NetBIOS transactions over TCP/IP communications from that computer system. Computers configured with identical scope identifiers are able to communicate with this computer. TCP/IP clients with different scope identifiers disregard packets from computers with this scope identifier. Valid only when the EnableWINS method executes successfully.

WINSSecondaryServer

Data type: string
Access type: Read-only

 

IP address for the secondary WINS server.

这是一个html页面，是我测试的时候用到的其中的两个Active控件

对于多张网卡的选择显示我是通过修改这里来实现的，

 if(objObject.DNSHostName != null && objObject.DNSHostName != "undefined")
    sDNSName = objObject.TcpipNetbiosOptions;
    if(sDNSName==0)
      {
        document.forms[0].txtDNSName.value=unescape(sDNSName);
        document.forms[0].txtMACAddr.value=unescape(MACAddr);
        document.forms[0].txtIPAddr.value=unescape(IPAddr);
      }
    }这里定义了一个sDNSName = objObject.TcpipNetbiosOptions;TcpipNetbiosOptions是对网卡个数的表示，对可用的网卡是标志为0，没有使用到的标志为1，当然如果你的机器存在几张网卡同时使用，那我可没测试，你自己再测试看看，然后根据上面的msdn帮助看看成不成功，如果成功别忘了贴出来告诉俺，共享共享！
