Wireshark · Ethereal-users: [Ethereal-users] Loopback storm? Odd capture file...

[Jim Thompson <jimstigator@xxxxxxxxx>]

Hello,

I've got a 100 Switched network and have noticed a
performance drag. I installed Ethereal and ran a
capture and got a TON of "loopback" packets from many
different MAC addresses. I tried the capture on
another machine and got the same results. I then used
MS "network monitor" and saw the same thing (I was
trying to rule out that the capture was local to just
one box). Anyone seen this before?:
