    1/2

    PingPing is a packet of data intended to check the route to and availability of another TCP/IP address. It does not always work on

    the Internet because many security administrators disallow ping in their firewalls (a good idea because ping can be used to

    create a rudimentary Denial-of-Service attack).

    Ping is the nickname given to sound wave transmittal/reflection in Active SONAR. Software Ping performs a similar function,

    transmitting a packet to and receiving information from a target. The original code was written by the late Mike Muuss in 1983.

    He won the 1993 Lifetime Achievement Award from University of California at Berkeley.

    Here is a windows ping of the servers at yahoo.com

    C:\>ping yahoo.com

    Pinging yahoo.com [66.218.71.198] with 32 bytes of data:

    Reply from 66.218.71.198: bytes=32 time=120ms TTL=246Reply from 66.218.71.198: bytes=32 time=100ms TTL=246Reply from 66.218.71.198: bytes=32 time=130ms TTL=246Reply from 66.218.71.198: bytes=32 time=101ms TTL=246

    Ping statistics for 66.218.71.198:Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),Approximate round trip times in milli-seconds:Minimum = 100ms, Maximum = 130ms, Average = 112ms

    Analysis of the ping response:

    Pinging yahoo.com [66.218.71.198] with 32 bytes of data:

    Resolves the address (tests to make sure the DNS works from your computer)

    Reply from 66.218.71.198: bytes=32 time=120ms TTL=246

    Shows the reply from your ping'ed internet address, including the time in milliseconds and the Time to Live. Time to live is ( in

    this example) a default value that tells the ping packet to expire if it does not reach the target in 246 hops. It is a value passed

    in the header of all IP (Internet Protocol) packets and was originally used to measure time.

    Ping statistics for 66.218.71.198:

    Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),

    Approximate round trip times in milli-seconds:

    Minimum = 100ms, Maximum = 130ms, Average = 112ms

    At the end of each ping is a s tatistics summary that can be used to determine if a problem exists. Even if ping returns a true

    (the TCP/IP address and the route to the address is valid from the originator), there may be a problem with the route. Look for a

    wide range of times between the three values (minimum, maximum, average) in the last line to determine if further investigation

    is needed.

    Vendor ClassificationAsked by Selva2007_SAP

    Hi Experts,

    I am working on Vendor Classification at present. My client would like to identifyVarious Vendors for a particular commodity group. What I have done is I havecreated a Vendor Class in cl02 and assigned various characteristics in cT04

    which are Commodity groups. But, then when I create Vendor Master I am notable to assign the Commodity group under the Vendor class as these

    characteristics are greyed out. I am not able to make a selection from theseCharacteristics.

    Secondly, where can I find out the list of Vendors which belong to a

    particular Material group? What is the T/Code here?Await your response quickly...

    Thanks!
