Ping Utility
ping is a computer network administration software utility used to test the reachability of a host on an Internet Protocol (IP) network. It is available for virtually all operating systems that have networking capability, including most embedded network administration software. Ping measures the round-trip time for messages sent from the originating host to a destination computer that are echoed back to the source. The name comes from active sonar terminology that sends a pulse of sound and listens for the echo to detect objects under water. Ping operates by means of Internet Control Message Protocol (ICMP) packets. ''Pinging'' involves sending an ICMP echo request to the target host and waiting for an ICMP echo reply. The program reports errors, packet loss, and a statistical summary of the results, typically including the minimum, maximum, the mean round-trip times, and standard deviation of the mean. The command-line options of the ping utility and its output vary between t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mike Muuss
Michael John Muuss (October 16, 1958 – November 20, 2000) was the American author of the freeware network tool ping. Career A graduate of Johns Hopkins University, Muuss was a senior scientist specializing in geometric solid modeling, ray-tracing, MIMD architectures and digital computer networks at the United States Army Research Laboratory at Aberdeen Proving Ground, Maryland when he died. He wrote a number of software packages (including BRL-CAD) and network tools (including ttcp and the concept of the default route or "default gateway") and contributed to many others (including BIND). However, the thousand-line ping, which he wrote in December 1983 while working at the Ballistic Research Laboratory, is the program for which he is most remembered. Due to its usefulness, ping has been implemented on a large number of operating systems, initially Berkeley Software Distribution (BSD) and Unix, but later others including Windows and Mac OS X. In 1993, the USENIX Associatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
