　　执行远程服务器的系统命令并获取内容：
　　boolean isAuthenticated = connection.authenticateWithPassword(user, password); logger.info("Connecting to " + ip + ":" + port + "successful"); Session sess = connection.openSession(); sess.execCommand("/usr/local/squid/bin/rotateBilli ng.sh -v"); InputStream stdout = new StreamGobbler(sess.getStdout()); BufferedReader br = new BufferedReader(new InputStreamReader(stdout)); StringBuffer sb = new StringBuffer(); while (true) { String line = br.readLine(); if (line == null) break; sb.append(line); } if (sb.toString().indexOf("0.0.4")
