powershell - 从 PowerShell 执行 nslookup

Question

我正在编写一个 powershell 来从服务器名称中获取 ip，这需要我将 nslookup 代码嵌入到我的 powershell 中

我该如何做整合工作？

有谁能够帮我？

Add-PSSnapin Microsoft.SharePoint.PowerShell
$web = Get-SPWeb -Identity “http://nycs00058260/sites/usitp“
$server_status = "PROD"
$list=$web.Lists[”DNS_Status”]
$items = $list.items 
Foreach($item in $items){
    $item_name = $item["Server_name"]  #need to get the ip by this name

    /*nslook up*/
     $item_name.update()

}

Answer 1

如果您安装PSCX模块，它会附带一个Resolve-Host用于处理名称查找的 cmdlet。

没有这一点，这个单线将完成这项工作

[System.Net.Dns]::GetHostAddresses("www.msn.com")

您也可以传入 IP 地址 - 但结果会有所不同。

Answer 2

Windows 8 和更高版本上的 PowerShell 3.0 附带一个Resolve-DnsNamecmdlet，可以获取以下信息：

(Resolve-DnsName $server_name)[0].IpAddress

Answer 3

只需使用：

Resolve-DnsName monServer | ? { # make selection here } | % { $_.IPAdress }  | select-object -first 1

#Here is a far better method for nslookup

# HOWTO ensure an nslookup results no errors but still gives the original names and column separations
$day = Get-Date -Format yyyyMMdd #<-- HOWTO set the day variable for today
$ErrorActionPreference = ‘SilentlyContinue’ #<-- HOWTO turn off error messages
$WarningActionPreference = 'SilentlyContinue' #<-- HOWTO turn off warning messages
$servers = Get-Content .\input\servers.txt
Foreach ($server in $servers){
$result = Resolve-DnsName $server -Server $env:LOGONSERVER.Remove(0,2) -Type ALL #<-- NSLOOKUP using your logon server
write-host ($server+","+$result.Name+","+$result.IPAddress) #<-- HOWTO Write two variables separated by a comma
}
$ErrorActionPreference = ‘SilentlyContinue’ #HOWTO turn on error messages
$WarningActionPreference = 'SilentlyContinue' #HOWTO turn on warning messages
