Hello,
I am using FreeBSD-6.2-PRERELEASE and when I ping to outside IP address get
below result.
gk# ping y.y.y.y

64 bytes from y.y.y.y: icmp_seq=13 ttl=43 time=520.129 ms (DUP!)
Above result shows there some row has (DUP!) message. I don't know why there
such message. Where can I get more detail information about it or it is error
happen to NIC?
Also included below information too.

Hi, The "DUP" means that "ping" received two replies to one enquiry - the icmp_sequence number is duplicated. In my case it was mistake in wifi configuration... Jaromir Dvoracek On 12.

I don't know why there such message. Where can I get more detail information about it or it is error happen to NIC?It's unlikely that this has anything to do with FreeBSD. It's more likely that a networking problem is causing packets to take multiple routes back at times, thus arriving twice. -- Bill Moran Collaborative Fusion Inc.
