如何在C＃中的SSH服务器上运行命令？ [英] How to run commands on SSH server in C#?

问题描述

我需要使用C＃代码执行此操作：

I need to execute this action using a C# code:

1. 在后台打开putty.exe（这就像cmd窗口一样） ）


2. 使用其IP地址登录到远程主机


3. 输入用户名和密码


4. 执行几个命令一个接一个地执行。


5. 运行另一个命令，该响应得到响应，告诉我在执行之前成功执行的命令

1. open putty.exe in the background (this is like a cmd window)
2. login to a remote host using its IP address
3. enter a user name and password
4. execute several commands one after the other.
5. run another command that gets a response telling me that the commands I ran before that where executed successfully

所以我正在尝试这样做：

So I'm trying to do it like this:

ProcessStartInfo proc = new ProcessStartInfo() 
{
     FileName = @"C:\putty.exe",
     UseShellExecute = true, //I think I need to use shell execute ?
     RedirectStandardInput = false,
     RedirectStandardOutput = false,
     Arguments = string.Format("-ssh {0}@{1} 22 -pw {2}", userName, hostIP, password)
     ... //How do I send commands to be executed here ?
};
Process.Start(proc);

推荐答案

您可以尝试https://sshnet.codeplex.com/ 。
这样，您根本不需要油灰或窗户。
您也可以获得答复。
看起来……。

You could try https://sshnet.codeplex.com/. With this you wouldn't need putty or a window at all. You can get the responses too. It would look sth. like this.

SshClient sshclient = new SshClient("172.0.0.1", userName, password);    
sshclient.Connect();
SshCommand sc= sshclient .CreateCommand("Your Commands here");
sc.Execute();
string answer = sc.Result;

编辑：另一种方法是使用shellstream。

Another approach would be to use a shellstream.

一次创建ShellStream：

Create a ShellStream once like:

ShellStream stream = sshclient.CreateShellStream("customCommand", 80, 24, 800, 600, 1024);

然后您可以使用以下命令：

Then you can use a command like this:

  public StringBuilder sendCommand(string customCMD)
    {
        StringBuilder answer;

        var reader = new StreamReader(stream);
        var writer = new StreamWriter(stream);
        writer.AutoFlush = true; 
        WriteStream(customCMD, writer, stream);
        answer = ReadStream(reader);
        return answer;
    }

private void WriteStream(string cmd, StreamWriter writer, ShellStream stream)
    {
        writer.WriteLine(cmd);
        while (stream.Length == 0)
        {
            Thread.Sleep(500);
        }
    }

private StringBuilder ReadStream(StreamReader reader)
    {
        StringBuilder result = new StringBuilder();

        string line;
        while ((line = reader.ReadLine()) != null)
        {
            result.AppendLine(line);
        }
        return result;
    }
