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(这就像一个cmd窗口)
2. 使用其 IP 地址登录到远程主机
3. 输入用户名和密码
4. 一个接一个地执行多个命令.
5. 运行另一个得到响应的命令，告诉我我之前运行的命令成功执行

所以我想这样做:

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

你可以试试 https://sshnet.codeplex.com/.有了这个，你根本不需要腻子或窗户.你也可以得到回应.它看起来……像这样.

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;

另一种方法是使用 shellstream.

Another approach would be to use a shellstream.

像这样创建一个 ShellStream:

Create a ShellStream once like:

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

然后你可以使用这样的命令:

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;
    }
