我正在尝试设置一个类,以便我可以ssh到远程服务器(我有IP,用户名和密码),然后发送一个命令,如“echo”test“”然后收回输出(例如,“测试”)。我正在使用JSch来做这件事,但我不明白该怎么做。
import com.jcraft.jsch.*;
public class ConnectSSH {
public int execute (String command) {
JSch jsch = new JSch();
String ip = "00.00.00.00;
String user = "root";
String pass = "password";
int port = 22;
try {
Session session = jsch.getSession(user, ip, port);
session.setPassword(pass);
session.connect();
...
我不知道该怎么办,连接后我被卡住了。
非常感谢任何建议。

试试这个:
JSch jsch=new JSch();
Session session=jsch.getSession(remoteHostUserName, RemoteHostName, 22);
session.setPassword(remoteHostpassword);
Properties config = new Properties();
config.put("StrictHostKeyChecking", "no");
session.setConfig(config);
session.connect();
ChannelExec channel=(ChannelExec) session.openChannel("exec");
BufferedReader in=new BufferedReader(new InputStreamReader(channel.getInputStream()));
channel.setCommand("pwd;");
channel.connect();
String msg=null;
while((msg=in.readLine())!=null){
System.out.println(msg);
}
channel.disconnect();
session.disconnect();

public void remoteLs() throws JSchException, IOException {
JSch js = new JSch();
Session s = js.getSession("myusername", "myremotemachine.mycompany.com", 22);
s.setPassword("mypassword");
Properties config = new Properties();
config.put("StrictHostKeyChecking", "no");
s.setConfig(config);
s.connect();
Channel c = s.openChannel("exec");
ChannelExec ce = (ChannelExec) c;
ce.setCommand("ls -l");
ce.setErrStream(System.err);
ce.connect();
BufferedReader reader = new BufferedReader(new InputStreamReader(ce.getInputStream()));
String line;
while ((line = reader.readLine()) != null) {
System.out.println(line);
}
ce.disconnect();
s.disconnect();
System.out.println("Exit code: " + ce.getExitStatus());
}
public void remoteMkdir() throws JSchException, IOException {
JSch js = new JSch();
Session s = js.getSession("myusername", "myremotemachine.mycompany.com", 22);
s.setPassword("mypassword");
Properties config = new Properties();
config.put("StrictHostKeyChecking", "no");
s.setConfig(config);
s.connect();
Channel c = s.openChannel("exec");
ChannelExec ce = (ChannelExec) c;
ce.setCommand("mkdir remotetestdir");
ce.setErrStream(System.err);
ce.connect();
BufferedReader reader = new BufferedReader(new InputStreamReader(ce.getInputStream()));
String line;
while ((line = reader.readLine()) != null) {
System.out.println(line);
}
ce.disconnect();

我建议查看JCraft网站上的隐藏示例:http://www.jcraft.com/jsch/examples/UserAuthKI.java
他们的示例提示输入用户名,主机名和密码,因此可以开箱即用。我在我的网络上运行它,并且能够连接到AIX服务器而无需更改任何代码。
注意,他们的例子有一个问题(这可能就是隐藏它的原因)..它不会关闭频道。如果发送'exit',服务器将断开连接,但通道对象保持打开状态,Java程序永远不会退出。我在这里提供了一个修复程序:Never ending of reading server response using jSch
