查找死网站/域的脚本 [英] Script to find dead website/domain

问题描述

我正在使用Powershell脚本来查找未在我们的服务器上运行或指向另一台服务器的网站.我正在从文件中获取所有网站名称，并使用它来查找那些不在我们的服务器上运行的网站.我正在尝试使用以下脚本，但出现错误.

I am working on a powershell script to find websites which are either not running on our server or pointing to another server. I am fetching all website names from a file and using it to find only those websites which are not running on our server. I'm trying to use below script but getting an error.

一如既往，我们将非常感谢您的帮助或建议.

As always, and help or advice would be much appreciated.

$servers = get-content "path_to_the_file"
foreach ($server in $servers) {
$addresses = [System.Net.Dns]::GetHostAddresses($server)
foreach($a in $addresses) {
"{0},{1}" -f $server, $a.IPAddressToString
 }
}     

以下是我得到的错误:

Exception calling "GetHostAddresses" with "1" argument(s): "No such host is known" At      
C:\test1.ps1:3 char:50 + $addresses = [System.Net.Dns]::GetHostAddresses <<<< ($server) + 
CategoryInfo : NotSpecified: (:) [], MethodInvocationException + FullyQualifiedErrorId : 
DotNetMethodException

推荐答案

只需捕获异常:

try {
    $addresses = [System.Net.Dns]::GetHostAddresses($server);
}
catch {
    $addresses = [IPAddress]'0.0.0.0';
}
