You (or one of your local Unix and Linux admins) should compare all of the FTP server and client default settings...
between Unix and Linux. However, that still may not provide the answer.
What is in the extra byte? 0x0D? You may be able to use a program on Linux to remove te extra byte. One I have heard of is called "dos2unix". The Unix tr (translate) command can also be used to delete the extra byte. Assuming the extra byte is a carriage return (CR), the command would look like this:
tr -d '\r' ‹input.file ›output.file
'n' if the extra byte is newline.
Hope this helps.
