Hello,

Call me crazy, but when I copied the text out from Mr. Casati's email, I
had to edit all of the line wraps that (I believed) Thunderbird injected
into the email.  Takes a bit but you'll find them.

If anything I got 'farther' into compiling myself, needed to reflect
some changes to a new location of a pcap-bpf.h header.

[~/sandbox]# gcc -DLINUX -lpcap storm.c -o storm
storm.c: In function `PCapHandler':
storm.c:450: warning: initialization from incompatible pointer type
/tmp/ccvPmT8m.o(.text+0x3e8): In function `TCPCheckSum':
: undefined reference to `sizephdr'
collect2: ld returned 1 exit status
[~/sandbox]#

Anyone have sucess in testing this out in a sandbox environment?
