ICMP-based ping utilities.

Details: Ping is a collection of functions for performing low level, ICMP-based ping tests on remote hosts.

Presently, Ping contains only one function, countReplies. More will be added later. If you have requests, please submit them to Sharkysoft.

Warning: Ping uses a few platform-dependent tricks. You should verify that this class works on your target platform before integrating it into your application. Run the stand-alone test by executing this class from the command line:

java lava.io.Ping <host> [<count>]

Ping has been tested and found operational on the following platforms:

• Windows 2000
• Red Hat Linux 7.0

If you test Ping and find that it works on another platform, please let Sharkysoft know so we can add the platform to the above list.
