DUPLICATE AND DAMAGED PACKETS
ping will report duplicate and damaged packets. Duplicate packets
should never occur, and seem to be caused by inappropriate link-level
retransmissions. Duplicates may occur in many situations and are
rarely (if ever) a good sign, although the presence of low levels of
duplicates may not always be cause for alarm.
Damaged packets are obviously serious cause for alarm and often indi-
cate broken hardware somewhere in the ping packet?s path (in the net-
work or in the hosts).
