Hi Michael,

yeah, I see dropped packages.
But did you mean only that wireshark didn't capture all packages on ubuntu=
=3F
Or did you mean that the packages will be really dropped by the kernel=3F

Because I think it's the first one, can I display the dropped packages - i=
s there any configuration for wireshark=3F

Regards
Frank
