Thread: opening Telnet Command Session

Thank you JavaPF,

For a quick response

For testing the below code will simulate the things:

import java.util.StringTokenizer;
import java.io.*;
 
class TelnetTest {
 
    public static void main(String args[]) {
        String ip = "<give an IP address to connect>";//or pass it as an argument
        String strCMD = "CMD.EXE /C start telnet " + ip;
 
        StringTokenizer st = new StringTokenizer(strCMD);
        String[] cmd = new String[st.countTokens()];
        int total = st.countTokens();
        for (int i = 0; i < total; i++) {
            cmd[i] = st.nextToken(" ");
        }
 
        try {
 
            ProcessBuilder processBuilder = new ProcessBuilder(cmd);
            processBuilder.directory(new File(System.getenv("temp")));
            processBuilder.redirectErrorStream(true);
 
            Process proc = processBuilder.start();
 
            /*
             * Now the child process is on and waiting for user ID
             */
            System.out.println("Trying to pass the telnet  user ID for the login: promt..");
            OutputStream out = proc.getOutputStream();//This should give me the access to stdout of the child
            out.write("user\n".getBytes());//provide a valid user name
            out.flush();
 
            System.out.println("Trying to pass the telnet  password for the password: promt..");
 
            out.write("pass\n".getBytes());
            out.close();
 
            int status = proc.waitFor();
 
 
        } catch (Throwable t) {
            t.printStackTrace();
        }
    }
}

Here I am not trying to use InputStream because I expect it to be visible in the telnet window.

Thanks again....
