FTP Connect Mode

Choose between an ​active or passive connection per bookmark or when opening a new connection. The default setting can be set in the System Preferences in Network → Advanced... → Proxies → Use Passive FTP Mode (PASV).

Character Encoding

The character encoding used to parse directory listings can be set as a per bookmark setting. See problems?.

TLS Connections (FTPS)

Only ​explicit TLS is supported.

Disable SSL/TLS X.509 certificate trust validation

If you have problems with the Keychain trust settings, you can use the following options to disable verification of certificates. Be aware that this a severely compromising security. This is not a recommended configuration. Before disabling trust verification, try to restart Cyberduck after editing the trust setting.

• Disable certificate validation for FTP-TLS:

defaults write ch.sudo.cyberduck ftp.tls.acceptAnyCertificate true

Server compatibility

ProFTPd

• You need to have the option set TLSOptions NoSessionReuseRequired for FTP-TLS connections. Issue #5087.
• You need to have the option set TLSOptions AllowClientRenegotiations for FTP-TLS connections. Issue #3012.

Make file listing parsers whitespace aware (FTP)

To make the parsers for directory listings aware of whitespace in filenames (leading or trailing), enter. This is already set by default.

defaults write ch.sudo.cyberduck ftp.parser.whitespaceAware true

To revert the behaviour, set this property to false if you have issues with filenames parsed with a leading whitespace as described in #2895.
