Would some be able to help me with a quick question, how does Ethereal identify FTP-Data packets - specificaly the ones which don't use either source or destination port 20 that is.

I have been going through the source but Im a bit overwhelmed and cant locate the section with the packet analysis.

Thank you in advance for any help,

Duncan Godfrey
