如何检查网络端口访问并显示有用的消息? [英] How to check Network port access and display useful message?

问题描述

我正尝试使用powershell来检查端口是否打开，如下所示.

I was trying to check whether the port is opened or not using powershell like follows.

(new-object Net.Sockets.TcpClient).Connect("10.45.23.109", 443)

此方法有效，但是输出不是用户友好的.这意味着如果没有错误，则可以访问.有什么方法可以检查是否成功并显示诸如端口443处于运行状态"之类的消息?

This method works , but the output is not user-friendly. It means if there are no errors then it has access. Is there any way to check for success and display some message like " Port 443 is operational"?

推荐答案

实际上，谢伊·莱维(Shay levy)的回答几乎是正确的，但正如我在他的评论专栏中提到的那样，我遇到了一个奇怪的问题.因此，我将命令分为两行，效果很好.

Actually Shay levy's answer is almost correct but i got an weird issue as i mentioned in his comment column. So i split the command into two lines and it works fine.

$Ipaddress= Read-Host "Enter the IP address:"
$Port= Read-host "Enter the port number to access:"

$t = New-Object Net.Sockets.TcpClient
$t.Connect($Ipaddress,$Port)
    if($t.Connected)
    {
        "Port $Port is operational"
    }
    else
    {
        "Port $Port is closed, You may need to contact your IT team to open it. "
    }
