I want to send a simple command with a java application over my windows computer to activate a python script on my raspberry pi which should control the GPIO ports of my raspberry Pi.
I don't get really into Jsch, my SSH connection already works but not sending commands.
Here is my actual code:
package sshtest;
import java.io.ByteArrayInputStream;
import java.io.InputStream;
import com.jcraft.jsch.*;
import java.io.InputStream;
public class SSHTest {
public static void main(String[] args) {
String host="DELETED";
String user="pi";
String password="DELETED";
String command =("cd Desktop");
String command2 =("sudo python IO2.py all high");
try{
java.util.Properties config = new java.util.Properties();
config.put("StrictHostKeyChecking", "no");
JSch jsch = new JSch();
Session session=jsch.getSession(user, host, 22);
session.setPassword(password);
session.setConfig(config);
session.connect();
System.out.println("Connected");
Channel channel = session.openChannel("exec");
InputStream is = new ByteArrayInputStream(command.getBytes());
channel.setInputStream(is);
InputStream iss = new ByteArrayInputStream(command2.getBytes());
channel.setInputStream(iss);
session.disconnect();
}catch(Exception e){
e.printStackTrace();
}
}
}
You should use ChannelExec.setCommand(java.lang.String) to start it, and wait while Channel.isClosed() returns false. BTW, JSch has an example for this: http://www.jcraft.com/jsch/examples/Exec.java.html.
