[BAT] merging dwepdump files

Fri, 19 Apr 2002 18:49:24 -0700 (PDT)

Hello,

I've noticed when merging large files, the final merge is a factor
larger than the sum of the previous files.  I'll try to recreate
this by not using client data, unlike the other files ;-)  IIRC,
one file was 400K while the other was 10K.  The result was above 4M
(once again, working from memory, so these numbers may be off, but
I recall the "4" and the final merge being roughly 10 times the
sum).  I only noticed this on larger merges, and not merging two
small files.

As stated, I'll try to replicate this when feasible.  The system
was FreeBSD 4.5-R using v0.2 of the bsd-airtools.  The card was a
Linksys.
