SSH2的两种java实现,jcraft和Ganymed,终于把困扰我多日的问题解决了,贴上来看看 [点击图片可在新窗口打开]
(看了源码,Ganymed好像就是对craft做了封装.)

/**

import com.jcraft.jsch.Channel;
import com.jcraft.jsch.ChannelSftp;
import com.jcraft.jsch.JSch;
import com.jcraft.jsch.Session;
import com.jcraft.jsch.UserInfo;

public class SSHTest {
public static final UserInfo defaultUserInfo = new UserInfo() {
  public String getPassphrase() {
   return null;
  }

  public String getPassword() {
   return null;
  }
  public boolean promptPassword(String arg0) {
   return false;
  }

  public boolean promptPassphrase(String arg0) {
   return false;
  }

  public boolean promptYesNo(String arg0) {
   return true;
  }

  public void showMessage(String arg0) {
  }
};

public static void main(String[] args) throws Exception {
  String hostname = "192.168.0.0";
  String username = "root";
  String password = "pass";
  String remoteFile = "/home/sun";
  String localFile = "C:\\001.txt";

  JSch jsch = new JSch();

  Session session = jsch.getSession(username, hostname, 22);
  session.setPassword(password);
  session.setUserInfo(defaultUserInfo);
  session.connect();
 
  Channel channel = session.openChannel("sftp");
  channel.connect();
  ChannelSftp c = (ChannelSftp) channel;
  c.put(localFile, remoteFile);
  session.disconnect();
}
}

    throw new IOException("Authentication failed.");

   Session sess = conn.openSession();

   sess.execCommand("cd /home/sun && mkdir test");

   sess.close();

   conn.close();

  catch (IOException e)

   System.exit(2);
