If I could determine the link-layer header that appears in the file
(NOTE: there is *NOT* always a simple correlation between the type of
interface on which the file was captured, due to various additional
headeers being added, link-layer headers being removed, headers being
transformed, etc.), I could suggest a command that would read the file
and write it out with a different link-layer type number.
15, unfortunately, is a type that means different things on different
platforms, due to a lack of central coordination for assignment of
values to link-layer types (which is why anybody who wants a link-layer
type should now go through tcpdump.org - before tcpdump.org existed,
people often just picked the "next available" number, and unfortunately
that meant that different people would pick the same number for
different purposes). That's why Ethereal doesn't support it.

I did, but the only software on my machine I know of that can handle
.rar files - Stuffit Expander - gave an error.
Could you just send LinkPoCal.cap as a binary attachment?
