如何测试远程系统是否可以访问

本文介绍了如何测试远程系统是否可以访问的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我想测试使用Java是否可以访问远程系统，或者换句话说使用Java发送ping".该功能应封装在具有布尔值的方法中，例如

I want to test whether a remote system is reachable using Java or in other words "send a ping" using Java. This functionality should be encapsulated in a method with boolean value, for example

public boolean isReachable(String ip) { // what to do :-) }

我已经测试了Java Process类，但是由于使用OutputBuffers进行复杂的输出处理，因此我认为这不是最好的方法.

I've tested the Java Process class, but I don't think that it is the best way to do this, because of the complex output handling with OutputBuffers.

Process proc = Runtime.getRuntime().exec("ping " + ip);

另一种可能性是创建一个Socket Connection并处理抛出的异常，但是如果远程系统是一个裸"的Unix系统，则另一端可能没有Socket :-)另外，我希望能够在无法访问远程系统时设置超时.

Another possibility would be creating a Socket Connection and handle thrown exceptions, but if the remote system is a "naked" unix system, there might be no Socket on the other side :-) Additionally, I'd like to be able to set a timeout, when a remote system is not reachable.

那我该怎么办呢?谢谢！

So how could I do this? Thank you!

推荐答案

InetAddress.getByName(ip).isReachable(timeout);
