FTP (remote file system) connection

To access your data with the FTP protocol, create a connection asset for it.

FTP is a standard communication protocol that is used to transfer files from a server to a client on a computer network.

Create an FTP connection

To create the connection asset, you need these connection details:

  • Connection mode: The connection method configured on the FTP server:
    • Anonymous
    • Basic authentication (with username and password)
    • SFTP Tectia: Transfer data sets that are in Multiple Virtual Storage (MVS) format to or from an IBM z/OS mainframe computer. MVS data sets use a period (.) to separate the qualifiers in the data set names. To write to an MVS data set, select Access MVS Dataset and enter the file transfer advice (FTADV) strings in key-value pairs separated by commas. For information, see the Tectia documentation.
    • SSH: File transfer over a secure channel that uses the Secure Shell protocol. Also requires username and password.
    • SSL: File transfer that uses File Transport Protocol (FTP), which supports secure transmission via SSL (sslTLSv2) protocol. Also requires username and password.
  • Hostname or IP address
  • Port number of the FTP server
  • SSH mode: Private key and Key passphrase
  • Authentication method:
    • Username and password
    • Username, password, private key. If you use an encrypted private key, you will need a key passphrase.
    • Username and private key. If you use an encrypted private key, you will need a key passphrase.

If you use a private key, make sure that the key is an RSA private key that is generated by the ssh-keygen tool. The private key must be in the PEM format.

For Credentials, you can use secrets if a vault is configured for the platform and the service supports vaults. For information, see Using secrets from vaults in connections.

Choose the method for creating a connection based on where you are in the platform

In a project
Click Assets > New asset > Data access tools > Connection. See Adding a connection to a project.
In a catalog
Click Add to catalog > Connection. See Adding a connection asset to a catalog.
In a deployment space
Click Add to space > Connection. See Adding connections to a deployment space.
In the Platform assets catalog
Click New connection. See Adding platform connections.

Next step: Add data assets from the connection

Where you can use this connection

You can use FTP connections in the following workspaces and tools:

Projects

  • Data Refinery (Watson Studio or Watson Knowledge Catalog)
  • DataStage (DataStage service). See Connecting to a data source in DataStage.
  • Metadata import (Watson Knowledge Catalog)
  • SPSS Modeler (SPSS Modeler service)

Catalogs

  • Platform assets catalog

  • Other catalogs (Watson Knowledge Catalog)

Federal Information Processing Standards (FIPS) compliance

The FTP connection is compliant with FIPS except for:

  • Connections that use SSL
  • SFTP Tectia connection mode

Supported file types

The FTP connection supports these file types:  Avro, CSV, Delimited text, Excel, JSON, ORC, Parquet, SAS, SAV, SHP, and XML.
