code: @Override
      public ChannelExec executeCommandChannel(String command) throws SshException, IOException {
          return executeCommandChannel(command, true);
      }
docs: This version takes a command to run, and then returns a wrapper instance
  that exposes all the standard state of the channel (stdin, stdout,
  stderr, exit status, etc).
  
  @param command the command to execute.
  @return a Channel with access to all streams and the exit code.
  @throws IOException  if it is so.
  @throws SshException if there are any ssh problems.
