Hello all,

        As I said before, forgive me, because my english is not so good!
        I'll make a "Multi-reply" in this email... It's easier ;)
        Thanks for all the replies!

        Sorry, I made a mistake when sent the email to Bugtraq. The
correct command (From Linux Slackware 3.6 Kernel 2.0.36) line is:

                ping -f -s 65000 IPaddr

        Hehe... But a synflood just made the LAN Communication slower,
and didn't affected Windows 98 than pingflood affected!
