do:

make
# (ignore the random error warnings, its due to libnet lameness)

./readtest &

and as root:

./7350somefoo -i lo -t 127.0.0.1 -p 2000
or
./7350somefoo -t <external-ip> -p 2000


it should show that 8192 bytes are read at once
try this with an external ip too, it should work 1:1 there, too.
