I noticed a number of postings elsewhere detailing this error when connecting to a server that didn't respond with a nice 227-line on the PASV command. I'm connecting to a WS_FTP server and ran into the same error, and I've gotten around it by hacking FTPSSL.pm to read deeper into the stack of returned messages from the server using getline(). I'll spare the details because this may have already been addressed, but if anyone else is interested let me know... akk
