I'm trying to make reboot modem application with java using telnet. But cmd stops when username must be entered.



private static void RebootModem()  throws IOException {

String tel = "telnet 192.168.1.1 23";
String user = "admin";
String pass = "admin";
String reboot = "reboot";
String command = "cmd /c start cmd.exe /c" +tel+ "/c" +user+ "/c" +pass+"/c" +reboot;

try
{
Process child = Runtime.getRuntime().exec(command);
PrintWriter out = new PrintWriter(child.getOutputStream(), true);
}
catch(IOException e)

{
e.printStackTrace();
}

    Print the command, you'll see what's wrong.

    I suggest you not using CMD, just use Sockets stackoverflow.com/questions/13894509/…

  • Besides that, it's not clear why you need /c after /c start
