Hello Mysterious Stranger (I assume "Admin" is not your first name),

Why don't we first try and see if your network stack is eating data.

Do something like this:

host1:~ # dd if=/dev/urandom of=/tmp/foobar bs=1M count=256
host1:~ # md5sum /tmp/foobar 

host2:~ # netcat -l -p 4711 | md5sum

host1:~ # netcat -q0 4711 < /tmp/foobar

... and let us know if those two MD5 sums match. Just in case, before we dive 
deeper into this.
