Wireshark · Wireshark-users: Re: [Wireshark-users] Ethernet FCS not verified

[Martin Isaksson <martin.isaksson@xxxxxxxxxxxx>]

Hi again,

here are two packets - one packet with incorrect FCS and the other with correct FCS (according to version 1.4.2).

Thanks,
Martin

Send us a sample capture that works with the older versions but not with the newer versions, to make it easier to figure out what changed in the Ethernet dissector's "this part of the trailer is probably an FCS" detector (there's no explicit indication of whether a frame ends with an FCS, so we just have some heuristics) and to make it easier to test whether a fix we make works?
