javassh登陆交换机执行命令

有人写过java ssh登陆交换机操作命令吗，不是telent也不是ssh下发linux指令 是ssh登陆交换机执行命令

第一步下载java扩展包

第二步：解压文件把 jar包，拷贝到java的库目录下，我的是ubuntu14（/usr/lib/jvm/java-7-openjdk-amd64/jre/lib/ext ）
cp ganymed-ssh2-build210.jar /usr/lib/jvm/java-7-openjdk-amd64/jre/lib/ext

第三步： 把默认账户修改成直接的账户密码

yang@yang:~/Downloads/java/ganymed-ssh2-build210/examples$ cat Basic.java
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;

import ch.ethz.ssh2.Connection;
import ch.ethz.ssh2.Session;
import ch.ethz.ssh2.StreamGobbler;

public class Basic
{
public static void main(String[] args)
{
String hostname = "127.0.0.1";
String username = "user";
String password = "password";

try
{

Connection conn = new Connection(hostname);

conn.connect();

boolean isAuthenticated = conn.authenticateWithPassword(username, password);

if (isAuthenticated == false)
throw new IOException("Authentication failed.");

Session sess = conn.openSession();

sess.execCommand("uname -a && date && uptime && who");

System.out.println("Here is some information about the remote host:");

InputStream stdout = new StreamGobbler(sess.getStdout());

BufferedReader br = new BufferedReader(new InputStreamReader(stdout));

while (true)
{
String line = br.readLine();
if (line == null)
break;
System.out.println(line);
}

System.out.println("ExitCode: " + sess.getExitStatus());

sess.close();

conn.close();

}
catch (IOException e)
{
e.printStackTrace(System.err);
System.exit(2);
}
}
}

第四步： 编译 javac Basic.java && java Basic
Here is some information about the remote host:
