Cyberduck Help / Howto / SFTP

Interoperability with OpenSSH

The following configuration options from ~/.ssh/config are supported for SFTP connections:

• IdentityFile for public key authentication.
• HostName aliases.
• User preference for login credentials.

Host keys are checked against and written to ~/ssh/known_hosts upon approval.

Advanced Authentication Methods

Public Key Authentication

Private keys containing a DSA or RSA private key in PEM format are supported (look for -----BEGIN DSA PRIVATE KEY----- or -----BEGIN RSA PRIVATE KEY----- in the file) and can be configured in the Bookmark or Connection? panel.

One-time password

Using a challenge-response authentication with one time password generators like SecurID is supported. After the initial login prompt for the username and password a second login prompt is displayed to enter the one-time passcode.

Using SCP for file transfers

Problems

• The error message Illegal sftp packet len may indicate you have an echo statement in your shell init script like .bashrc. Make sure it does not output any text.
