自动化远程登录使用PowerShell [英] Automating Telnet with PowerShell

问题描述

如何编写PowerShell脚本这个命令集自动化？

How can I write a PowerShell script to automate this set of commands?

• 远程登录到一台机器，


• 执行一些命令，


• 分析在Telnet窗口输出，


• 基于输出，发送几个命令

推荐答案

确定这是不是最优雅的解决方案，它并依靠 不寒而栗的 VBscript的，但在这里它会...

Ok this isn't the most elegant solution, and it does rely on shudder VBscript but here it goes...

创建一个VBScript实际加快telnet会话，这是一个例子。

Create a VBScript to actually expedite the telnet session, this is an example

set oShell = CreateObject("WScript.Shell")
oShell.run("Telnet")
WScript.Sleep 1000
oShell.SendKeys("Open 127.0.0.1 23")
WScript.Sleep 1000
oShell.SendKeys("{Enter}")
WScript.Sleep 1000
oShell.SendKeys("n")
WScript.Sleep 1000
oShell.SendKeys("{Enter}")
WScript.Sleep 1000
oShell.SendKeys"MyName"
WScript.Sleep 1000
oShell.SendKeys("{Enter}")
WScript.Sleep 1000
oShell.SendKeys("MyPassword")
WScript.Sleep 1000
oShell.SendKeys("{Enter}")
WScript.Sleep 1000
oShell.SendKeys("MyCommand")
WScript.Sleep 1000
oShell.SendKeys("{Enter}")
WScript.Sleep 1000

然后使用PowerShell来调用该脚本，并通过你想要执行的命令，在下面的例子中，这些命令存储在一个名为CommandList.txt文件

Then use Powershell to invoke that script and pass it the commands you want executing, in the example below these commands are stored in a file called CommandList.txt

function Connect-MyTelnet{
Param(
 [string] $IPAddress,
 [string] $Port,
 [string] $UserName,
 [string] $Password,
 [string] $cmdlistPath
)
    ## - Setting default values:
    if($port -eq $null){ $Port = "23"; };
    if($cmdlistPath -eq $null) { $CmdlistPath = 'c:\temp\cmdlist.txt'; };

    ## create vbscript file: MyTelnetSession.vbs
    ## - For Microsoft Telnet:
    $MyVBScript = @"
                   set oShell = CreateObject("WScript.Shell")`r`n
                   oShell.run("Telnet")`r`n
                   WScript.Sleep 1000`r`n
                   oShell.SendKeys("Open $IPAddress $Port")`r`n
                   WScript.Sleep 1000`r`n
                   oShell.SendKeys("{Enter}")`r`n
                   WScript.Sleep 1000`r`n
                   oShell.SendKeys("n")`r`n
                   WScript.Sleep 1000`r`n
                   oShell.SendKeys("{Enter}")`r`n
                   WScript.Sleep 1000`r`n
                   oShell.SendKeys("$UserName")`r`n
                   WScript.Sleep 1000`r`n
                   oShell.SendKeys("{Enter}")`r`n
                   WScript.Sleep 1000`r`n
                   oShell.SendKeys("$Password")`r`n
                   WScript.Sleep 1000`r`n
                   oShell.SendKeys("{Enter}")`r`n
                   WScript.Sleep 1000`r`n
                 "@;

    ## - Get file with telnet commands:
    [array] $Cmdlist = Get-Content $cmdlistPath;

    ## loop through and build each telnet command line:
    foreach($cmd in $cmdlist)
    {
        ## - Build VBscript lines:
        $MyVBScript += 'oShell.SendKeys("'+$cmd+'")'+"`r`n";
        $MyVBScript += "WScript.Sleep 1000`r`n";
        $MyVBScript += 'oShell.SendKeys("{Enter}")'+"`r`n";
        $MyVBScript += 'WScript.Sleep 1000'+"`r`n";
    }

    ## - Close Telnet Session:
        $MyVBScript += 'oShell.SendKeys("  QUIT")'+"`r`n";
        $MyVBScript += "WScript.Sleep 1000`r`n";
        $MyVBScript += 'oShell.SendKeys("{Enter}")'+"`r`n";
        $MyVBScript += 'WScript.Sleep 1000'+"`r`n";

    ## - Save and execute generated VBscript:
    $MYVBScript | Out-File -FilePath c:\temp\MyTelnet.vbs -Encoding ASCII;
    & c:\temp\MyTelnet.vbs
}; Set-Alias ct Connect-MyTelnet;

和应该做你的要求...

And that should do what you are asking...

请注意：不是我的解决方案，从这个发现博客文章和我已经使用它一次或两次。

Note: Not my solution, found from this blog post and I have made use of it once or twice.
