Ethernet data corruption?

[Kevin Breit]

Hi,
	The other night, my friend was sending me a video over the internet. 
We tried http, ftp, and other protocols, using different download
applications.  It seemed to be corrupt, the same way, everytime.  It
wouldn't work, and had a different md5sum than the "good" version on my
friend's computer.  Eventually we got it working.
	The same issue came up again today.  I uploaded my Java project on my
professor's server and it gives me an error.  However, if I load the
html file with the Java applet in my web browser from this hard disk
(instead of from the prof's), it works.
	I am wondering if there is some sort of corruption going on here.  I am
using Red Hat's 2.4.9-21 kernel.

Thanks
