#10704: FTP Feature 'File transfer: use browser connection' does not work
-----------------------+-------------------
Reporter: zapta | Owner:
Type: defect | Status: new
Priority: normal | Milestone:
Component: core | Version: 6.9.4
Severity: normal | Keywords: ftp
Architecture: Intel | Platform:
-----------------------+-------------------
To reproduce:
1. Using Cyberduck 6.9.4 on Mac OSX (I am using 10.14.4) define an FTP
connection with this parameters https://i.imgur.com/ILpx6h0.png (notice
the 'Use browser connection' and 'PASV' settings)
2. Setup a network sniffer to view the cyberduck traffic (I am using
Wireshark)
3. Establish the ftp connection and open a directory with a file.
4. Initiate a Download operation and view the captured packets in the
network sniffer.
Expected: Cyberduck use the existing FTP control connection to initiate a
PASV file transfer (as it does when opening a sub directory in the FTP
browser)
Actual: Cyberduck tries to open a new command connection at the host FTP
port (viewed as a SYNC packet).
Impact: this prevents using Cyberduck with network appliances that are
limited to a single FTP connection. FileZilla on the other hand works as
expected with those appliances.
