Hello,
i tryed to capture with a passive network tap

( wiring like: http://www.it-dienstleistungen.de/wp-content/uploads/passive_fig_2-300x270.gif )
a host with 100MB/FULL, use two diffrent usb-ethernet cards ( with 100MB/FULL too, checked with ethtool )
on "tap a" and "tab b".

See in wireshark "Info column": ETHERNET FRAME CHECK SEQUENCE INCORRECT

Is there a setup for the usb-ethernet cards
to get it work fine ? What did I wrong ?

 

Wireshark is running on a Linux System

 

http:  ETHERNET FRAME CHECK SEQUENCE INCORRECT

icmp:  (no response found!) ETHERNET FRAME CHECK SEQUENCE INCORRECT

Thanks

Dennis
