Hello List,
I'm running a ping command to monitor our connection to the Internet. Around yesterday, I was getting a lot of (DUP!) text on the replies.
Would anyone know what that means?
man ping
... [snip] ... 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).
