LOGGER.debug("Command To be Executed: " + command);             

channel.setCommand(command);
channel.connect();

//capture output
String msg;

StringBuffer output = new StringBuffer();
while ((msg = in.readLine()) != null)
{
    //output = output + msg;
    output.append(msg);
}

LOGGER.debug("Output Message = " + output.toString());

LOGGER.debug("ERROR STATUS --" + channel.getExitStatus());

channel.disconnect(); …
