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 Engine and the remote host, to rename or or delete files or directories.

note

The FTP protocol should not be confused with SFTP. While similar in names, FTP and SFTP use different protocols and offer different ways of transferring files. If you want to use the SFTP protocol, refer to ConnectorTypeSFTP

For more on the differences between FTP and SFTP refer to Difference between FTP and SFTP
