[plug] ping yields "wrong data byte #0 should be 0x9a etc" -- why?

[daniel at iinet.net.au]

Hi Plug, I wonder if someone can explain this to me please -- ping gives me 
errors I haven't seen before.
I looked through the help and the man pages, and if it's there I missed it.
=================
sample: ( ~ 21.45 Friday on iinet using rsync to a Mandrake mirror in the 
US in one terminal and I ping iinet from another and get this:)

wrong data byte #0 should be 0x9a but was 0x9999 f9 4e 3b 6c d a 0
