file corruption

[Ben Paley]

Hello,

This is more or less a copy of a message I sent to questions@ - someone kindly 
advised me to try here.

I have apache-2.0.55_4 running on FreeBSD 6.1-PRERELEASE on a laptop on a 
small office lan. Whenever one of the other machines (mostly Macs) makes a 
request for a certain page on my machine, it is delivered succesfully but the 
file itself is absolutely scrambled beyond recognition into a binary file. 
Subsequent requests rescramble it into a different but equally nonsense 
binary.

I've looked with a binary editor and it really is completely messed up. I can 
restore the file from a good archive copy, but every time the same thing 
happens.

The file was originally created on a mac by Flash (it's a 1.1k html file which 
just embeds a flash movie). Recently I copied it to and from a Solaris box 
via ftp from an Windows NT machine (although it wasn't opened afaik - a long 
story, clearly, which also involves a usb flash drive...).

Since I posted originally to questions@ I have noticed some other strange 
corruptions, for instance a file which was fine on my machine but became a 
binary (although it looked ok) after ftp onto a remote machine. This happened 
with 2 different gui clients and the command line, and happened in ascii, 
binary or auto mode.

If this is related, it seems to absolve apache... but I'm not sure it is.

Anyone have any ideas? The file itself is inconsequential, but I'm very 
worried lest it should start elsewhere.

Cheers,
Ben
