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。
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;
public bool _ready;
public void OnData(byte[] data, int offset, int length)
{
System.Console.Write(Encoding.ASCII.GetString(data, offset, length));
}
public void OnDebugMessage(bool always_display, byte[] data)
{
Debug.WriteLine("DEBUG: " + Encoding.ASCII.GetString(data));
}
public void OnIgnoreMessage(byte[] data)
{
Debug.WriteLine("Ignore: " + Encoding.ASCII.GetString(data));
}
public void OnAuthenticationPrompt(string[] msg)
{
Debug.WriteLine("Auth Prompt " + msg[0]);
}
public void OnError(Exception error, string msg)
{
Debug.WriteLine("ERROR: " + msg);
}
public void OnChannelClosed()
{
Debug.WriteLine("Channel closed");
_conn.Disconnect("");
//_conn.AsyncReceive(this);
}
public void OnChannelEOF()
{
_pf.Close();
Debug.WriteLine("Channel EOF");
}
public void OnExtendedData(int type, byte[] data)
{
Debug.WriteLine("EXTENDED DATA");
}
public void OnConnectionClosed()
{
Debug.WriteLine("Connection closed");
}
public void OnUnknownMessage(byte type, byte[] data)
{
Debug.WriteLine("Unknown Message " + type);
}
public void OnChannelReady()
{
_ready = true;
}
public void OnChannelError(Exception error, string msg)
{
Debug.WriteLine("Channel ERROR: " + msg);
}
public void 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;
}
public void EstablishPortforwarding(ISSHChannelEventReceiver rec, SSHChannel channel)
{
_pf = channel;
}
public SSHChannel _pf;
}
3.好的，现在来测试一下：
class
Program
{
private static SSHConnection _conn;
static void 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 = new byte[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);

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。
