Network interfaces don't have device special files, or in English, /dev/ directory entries, i.e. /dev/de0 doesn't really exist. It looks like you copied the /COPYRIGHT file to /dev/de0 as a test, and when you cat it back out, surprise, you get the original file back :-) It doesn't make much sense to `cat' a file down an Ethernet, it has to be chopped up into packets and you have to specify a port and destination and all that stuff which makes Ethernet work. > The same thing happened to /dev/null a couple of months ago, but since > things seemed to function normally, I ignored it. Perhaps you had some corruption in your /dev/ directory. You can usually fix errant devices by running /dev/MAKEDEV as root.
