Concurrent pings

This is an excellent script to call from within Windows to verify another device is available.

I’ve added three enhancements: 1) randomized the temp file name to avoid a collision if called concurrently (eg: two nagios servers), 2) explicitly delete the temp file and 3) added perfdata in the return.

I also capitalized the file.
