Powershell Invoke-SSHCommand:使用“1"参数调用“EndExecute"异常 [英] Powershell Invoke-SSHCommand: Exception calling “EndExecute” with “1” argument(s)

问题描述

我正在尝试通过 powershell 中的 Posh-SSH 模块连接到 Netscaler SDX 服务器，以搜索特定文件，然后下载它.如果我用腻子连接到服务器，它就可以工作，然后我可以输入shell"来打开一个普通的 bash 控制台.当我尝试使用 powershell 连接时，我使用以下命令.

I'm trying to connect to a Netscaler SDX server via the Posh-SSH module in powershell, to search for a specific file and then download it. If i connect to the server with putty it works and I can then enter "shell" to open a normal bash console. When i try to connect with powershell i use following commands.

$hostname = [ip]
$user = [username]
$password = [password]

$secureStringPwd = $password | ConvertTo-SecureString -AsPlainText -Force
$creds = New-Object System.Management.Automation.PSCredential -ArgumentList 
$user, $secureStringPwd

$ssh = New-SSHSession -ComputerName $HostName -Credential $creds

这会创建一个仍然可以正常工作的 ssh 会话.接下来我使用 Invoke-SSHCommand.

This creates a ssh session which still seams to work. Next I use Invoke-SSHCommand.

Invoke-SSHCommand -SessionId ssh.SessionId -Command "shell"

它加载了一段时间然后抛出这个异常:

It loads for a while and then throws out this exception:

Exception calling "EndExecute" with "1" argument(s):  "Command 
'shell' has timed out."

我用谷歌搜索，我只找到了一个有同样问题但没有答案的人(用它来从德语翻译成英语).我还尝试了其他命令，例如ls"，但返回了相同的错误.有人知道我做错了什么吗?

I googled for it, I only found someone with the same problem but no answer (used that to translate from german to english). I also tried other things like "ls" for commands but the same error returned. Does someone have an Idea what I am doing wrong?

我使用的是 Windows 10 和 Powershell 5.1

I'm using Windows 10 and Powershell 5.1

推荐答案

我遇到了完全相同的问题.尝试 SSHStream 命令:

I had exactly the same problem. Try SSHStream commands:

PS C:\> $SSHStream = New-SSHShellStream -Index 0
PS C:\> $SSHStream.WriteLine("uname -a")
PS C:\> $SSHStream.read()
