Using the Rsh class

You may create a new Rsh instance providing the remote host, username, local username command and error stream arguments to the constructor.  The username represents the user whose credentials are to be used to execute any commands whereas the local username is the user who you will login as.  In many cases these may be the same.  The command is the command you wish to execute and the last argument determines whether the error stream should be initialized separately.

Example

Rsh rsh = new Rsh("remote.host.com", "johndoe", "johndoe","ls -la", false);

try

{

  // establish connection

  rsh.connect();

  // execute command

  rsh.execute();

  // get input stream

  InputStream input = rsh.getInputStream();

  // read first byte to determine success or failure

  int in = input.read();

  StringBuffer buffer = new StringBuffer();

  if(in == 0)

  {

     buffer.append("Success! Remote host returned: \n");

  }

  else

  {

     buffer.append("Failure! Remote host returned: \n");

  }

// read response        

  while((in = input.read()) != -1)

  {

     buffer.append((char)in);

  }

  System.out.println(buffer.toString());

}

catch(Exception e)

{

  System.out.println(e);

}
