I have a task to make a simple console pinger in Java. I tried the following code and I have 2 main issues.
First of all even if I am connected to the internet (I can ping from console any site), when I run the code returns false.
Second, is it possible to track the time of response of the ping?
Here is the code:
try {
InetAddress address = InetAddress.getByName(the_link);
System.out.println(the_link);
// Try to reach the specified address within the timeout
// periode. If during this periode the address cannot be
// reach then the method returns false.
boolean reachable = address.isReachable(5000);
System.out.println("Is host reachable? " + reachable);
} catch (Exception e) {
e.printStackTrace();
}
This is not a good one to use for most external ips. Instead following can be used
boolean reachable = (java.lang.Runtime.getRuntime().exec("ping -c 1 www.google.lk").waitFor()==0);
