Java psexec interactive remote command line

Question

I'm having an issue with psexec where it's not interactive. It returns as soon as it has run the command to open command prompt

Here is my Connection class:

package testProject;

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.io.PrintStream;


public class ConTest {

    private ProcessBuilder process;
    private Process connection;
    private String main_connection;;

    public ConTest(String host, String user, String password) {
        process = new ProcessBuilder("cmd.exe");
        process.redirectErrorStream(true);
        main_connection="<path to psexec>\psexec.exe \\\\" + host + 
                " -accepteula -nobanner -u " + user + " -p " + password +" cmd";
    }

    public void runCommand(String command) throws Exception{

        /* Variable Declaration */
        String          readline;
        PrintStream     output;
        BufferedReader  input;

        /* Variable Initialization */
        connection = process.start();
        output = new PrintStream(connection.getOutputStream());
        input = new BufferedReader(new InputStreamReader(connection.getInputStream()));

        /* Running the commands on the Host */

        output.println(main_connection);
        output.println(command);
        output.println("exit");
        output.close();

        /*print the output from the command*/
        while ((readline = input.readLine()) != null) {
            System.out.println(readline);
        }

        input.close();
        connection.waitFor();
    }
}

And then I'm calling it using the following

package testProject;

public class mainClass {

    public mainClass() {
    }

    public static void main(String[] args) throws Exception {

        ConTest con = new ConTest(<IP>, <Admin>, <Password>);
        con.runCommand("ping localhost");

    }
}

The output shows that it connects to the host but then it just disconnects before writing the ping localhost command

Here is the output

C:><path to psexec>\psexec.exe \\<IP> -accepteula -nobanner -u <Admin> -p <Password> cmd
Microsoft Windows [Version 6.1.7601]Connecting to <IP>...


Starting PSEXESVC service on <IP>...


Connecting with PsExec service on <IP>...


Starting cmd on <IP>...



cmd exited on <IP> with error code 0.

C:\>ping localhost

followed by the ping stats

How can I keep the command prompt the focus of the output stream so when I send more commands down the pipe they are executed on the remote machine not my local machine?

Answer 1

I used paexec instead of psexec and it managed to give me an interactive session, hope this helps someone in the future
