Wireshark · Ethereal-dev: [Ethereal-dev] Incorrect TCP checksums

["Stuart MacDonald" <stuartm@xxxxxxxxxxxxxxx>]

Ethereal: 0.10.4
Interface: GTK2
OS: Windows XP

I'm getting a lot of, but not all, packets with an incorrect TCP
checksum reported.

I think this is a bug in Ethereal, but am not 100%.

Older traces I had saved also show up incorrect checksums, but I may
not have noticed them before, not having the [] in the packet list to
notify me.

Simultaneous captures (both attached) show incorrect for the capture
from the machine ethereal was on, but correct for the tcpdump from my
linux box, although I used the same ethereal to look at the tcpdump.

Anyone else seeing this?

As always, available to do more testing, etc.
