How do I get a list of the active IP-addresses, MA

How do I get a list of the active IP-addresses, MAC-addresses and NetBIOS names on the LAN?

I'd like to get NetBIOS name, IP and MAC addresses for every host on the LAN, preferably not having to walk to every single PC and take note of the stuff myself.

How to do that with Windows Script Host/PowerShell/whatever?

回答1:

As Daren Thomas said, use nmap.

 nmap -sP 192.168.1.1/24

to scan the network 192.168.1.*

 nmap -O 192.168.1.1/24

to get the operating system of the user. For more information, read the manpage

 man nmap

regards

回答2:

arp -a

That gets everything the current machine knows about on the network.

(I'm putting this up there as a second option, since nmap isn't universally installed).

If you're using DHCP then the server will give you a list of all that information.

This website has a good tutorial on using powershell to get networking information http://www.powershellpro.com/powershell-tutorial-introduction/powershell-scripting-with-wmi/

If you neet to get quick list of computer names you can use "net view". Also have a look at nbmac although I'm unsure of it's working status under XP. Another option could be to use nbtstat -a (once you've used net view to list workstations)

In PowerShell you can do something like:

$computers = "server1","server2","server3"

Get-WmiObject Win32_NetworkAdapterConfiguration -computer $computers -filter "IPEnabled ='true'" | select __Server,IPAddress,MACAddress

In PowerShell:

function Explore-Net($subnet, [int[]]$range){
    $range | % { test-connection "$subnet.$_" -count 1 -erroraction silentlycontinue} | select -Property address | % {[net.dns]::gethostbyaddress($_.address)}
}

Example:

Explore-Net 192.168.2 @(3..10)
