ConnectorTypeFTP

class connector_types.connector_type_ftp.ConnectorTypeFTP

Connect to a FTP server.

This connector type uses the FTP protocol to list folder contents, to transfer files between Cloudomation and the remote host, to rename or or delete files or directories.

Currently supported connection methods:

• plain FTP: not encrypted, insecure
• implicit FTPS: FTP over TLS

Currently unsupported connection methods:

• explicit FTPS: plain FTP upgrading to TLS using the AUTH command
• SFTP: SSH file transfer protocol
