Polling For 100 mbps Connections? (Was Re: Freebsd Theme Song)

In looking at this again, I didn't realize you were pinging from
Win2K

Win2K uses the -f option to set the Do Not Fragment bit, UNIX uses
the -f option to flood ping.  Win2k ping does not have a flood ping
option.  You can download a ping for Windows from Microsoft here:

http://research.microsoft.com/barc/mbone/mping.aspx

that does have an option for flooding traffic. ( set the milliseconds
between packets very low) but I have not tested it.  Doubtless
others are available on the Internet.
