The "best" version of "ping"?

[Vince Fuller <vaf () Valinor BARRNET NET>]

Throughout the years, I've seen a number of different versions of "ping" with
various features like:

    - "-f" switch which pings a destination as fast as possible
    - "-c" switch which acts like the ping function on a cisco router
    - TTL reporting
    - improved clock resolution
    - ability to specify data pattern
    - ability to source jumbograms

I would be interested in finding versions of "ping" with such "enhanced"
functionality. Does anyone have either a canonical "best" version that
incorporates many/all of these enhancements or, failing that, pointers to
various versions which incorporate different sets of features?

        Thanks,
