For passive FTP see;
epan/dissectors/packet-ftp.c
Function dissect_ftp
Then look for 'is_pasv_response'

Subject: [Ethereal-dev] Protocol Identification
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
