我想在 ping 主机后获取 ping 执行时间和结果字符串

Question

我想在 ping 主机后获取 ping 执行时间和结果字符串。我该怎么做呢？

Answer 1

long currentTime = System.currentTimeMillis();
boolean isPinged = InetAddress.getByName(servername).isReachable(2000); // 2 seconds
currentTime = System.currentTimeMillis() - currentTime;
if(isPinged) {
    System.out.println("pinged successfully in "+ currentTime+ "millisecond");
} else {
    System.out.println("PIng failed.");
}

但这只会在Windows系统中使用ICMP ping。

你检查过了吗
http://docs.oracle.com/javase /1.4.2/docs/guide/nio/example/Ping.java

和

http://www.java2s.com/Code/JavaAPI/java.net/InetAddressReachableinttimeout .htm

Answer 3

long start = System.currentTimeMillis();
long ping;




String[] command = { "cmd.exe", "/C", "ping 192.168.1.101" };
commandProcess = Runtime.getRuntime().exec(command);
BufferedReader buffy = new BufferedReader(new InputStreamReader(commandProcess.getInputStream()));
String readline;
while((readline = buffy.readLine())!=null){
System.out.println(readline);
if(readline.contains("reply")){
 long ping = System.currentTimeMillis();
 System.out.println("Pinged in:"+ ping);
 }
}
 long end = System.currentTimeMillis();
 String done = "Completed in times:" +start + ping +end;

Answer 4

这就是我使用它的方式 -

private static void checkPing(String hostName) {

    String[] command = { "cmd.exe", "/C", "ping " + hostName };
    try {
        Process p = Runtime.getRuntime().exec(command);
        BufferedReader buff = new BufferedReader(new InputStreamReader(p.getInputStream()));
        String readline;
        while ((readline = buff.readLine()) != null) {
            if (readline.contains("Reply")) {
                System.out.println("Pinged " + hostName + " in : "
                        + readline.substring(readline.indexOf("time=") + 5, readline.indexOf("ms")) + " ms");
            }
        }
    } catch (IOException e) {
        e.printStackTrace();
    }
}

为您提供每个 ping 请求的精确（可靠）ping 延迟（以毫秒为单位）。
如果需要，您可以添加其中的四个
