SSH连接远程Linux服务器(C#)

   转载自:http://blog.csdn.net/lusonglin3g/article/details/4801247

Granados是一个基于.NET的SSH客户端库。它有以下特点：
1.Granados是一个C#的开源项目。源码地址：http://www.routrek.co.jp/support/download/varaterm/granados200.tar.gz
2.同时支持SSH1和SSH2。
3.Granados实现了AES, Blowfish, TripleDES, RSA, DSA等加密验证算法。
4.实现TCP协议连接。

如何使用Granados库

可惜的是Granados的文档几乎没有！所以只有从它的源码找到它的测试代码来看。总结步骤为：

1.工程中添加Routrek.granados.dll(下载的包里有)的引用。

2.添加Reader类，实现ISSHConnectionEventReceiver和ISSHChannelEventReceiver接口。首先引用命名空间：

using System.Threading;
using System.Diagnostics;
using System.Net;
using System.Net.Sockets;
using Routrek.Crypto;
using Routrek.SSHC;
using Routrek.SSHCV1;
using Routrek.SSHCV2;
using Routrek.Toolkit;
using Routrek.PKI;

Reader类实现如下：

class Reader : ISSHConnectionEventReceiver, ISSHChannelEventReceiver
{
public SSHConnection _conn;
publicbool _ready;

publicvoid OnData(byte[] data, int offset, int length)
{
           System.Console.Write(Encoding.ASCII.GetString(data, offset, length));
       }
publicvoid OnDebugMessage(bool always_display, byte[] data)
{
           Debug.WriteLine("DEBUG: "+ Encoding.ASCII.GetString(data));
       }
publicvoid OnIgnoreMessage(byte[] data)
{
           Debug.WriteLine("Ignore: "+ Encoding.ASCII.GetString(data));
       }
publicvoid OnAuthenticationPrompt(string[] msg)
{
           Debug.WriteLine("Auth Prompt "+ msg[0]);
       }

publicvoid OnError(Exception error, string msg)
{
           Debug.WriteLine("ERROR: "+ msg);
       }
publicvoid OnChannelClosed()
{
           Debug.WriteLine("Channel closed");
           _conn.Disconnect("");
//_conn.AsyncReceive(this);
       }
publicvoid OnChannelEOF()
{
           _pf.Close();
           Debug.WriteLine("Channel EOF");
       }
publicvoid OnExtendedData(int type, byte[] data)
{
           Debug.WriteLine("EXTENDED DATA");
       }
publicvoid OnConnectionClosed()
{
           Debug.WriteLine("Connection closed");
       }
publicvoid OnUnknownMessage(byte type, byte[] data)
{
           Debug.WriteLine("Unknown Message "+ type);
       }
publicvoid OnChannelReady()
{
           _ready =true;
       }
publicvoid OnChannelError(Exception error, string msg)
{
           Debug.WriteLine("Channel ERROR: "+ msg);
       }
publicvoid OnMiscPacket(byte type, byte[] data, int offset, int length)
{
       }

public PortForwardingCheckResult CheckPortForwardingRequest(string host, int port, string originator_host, int originator_port)
{
           PortForwardingCheckResult r =new PortForwardingCheckResult();
           r.allowed =true;
           r.channel =this;
return r;
       }
publicvoid EstablishPortforwarding(ISSHChannelEventReceiver rec, SSHChannel channel)
{
           _pf = channel;
       }

public SSHChannel _pf;
   }

3.好的，现在来测试一下：

class Program
{
privatestatic SSHConnection _conn;
staticvoid Main(string[] args)
{
           SSHConnectionParameter f =new SSHConnectionParameter();
           f.UserName ="root";
           f.Password ="****";
           f.Protocol = SSHProtocol.SSH2;
           f.AuthenticationType = AuthenticationType.Password;
           f.WindowSize =0x1000;
           Reader reader =new Reader();
           Socket s =new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
           s.Connect(new IPEndPoint(IPAddress.Parse("192.168.x.x"), 22));
           _conn = SSHConnection.Connect(f, reader, s);
           reader._conn = _conn;
           SSHChannel ch = _conn.OpenShell(reader);
           reader._pf = ch;
           SSHConnectionInfo ci = _conn.ConnectionInfo;

           Thread.Sleep(1000);

byte[] b =newbyte[1];
while (true)
{
int input = System.Console.Read();
               b[0] = (byte)input;
               reader._pf.Transmit(b);
           }

       }
   }

4.执行效果如下：


5.如果你需要快速的执行某些指定的命令，则可以把上面的

byte [] b = new byte [ 1 ];
while ( true )
{
int input = System.Console.Read();
     b[0] = (byte)input;
     reader._pf.Transmit(b);
}

替换为：

string cmd = " vi xxx.txt/n " ;
byte [] data = ( new UnicodeEncoding()).GetBytes(cmd);
reader._pf.Transmit(data);
