Set up an FTP connection 

Create an FTP connection

1. Go to the Resources menu and click Connections. The Connections page opens.

2. Click + Create connection and select FTP from the Application list. The Create connection pane displays.

3. Name your Connection so that you can easily reference it from other parts of the application.
4. Click Next to continue and describe your FTP connection.

Configure an FTP connection

You can configure your FTP connection using the following protocols:

• FTP, or file transfer protocol – not recommended due to lower security
• SFTP, or secured file transfer protocol
• FTPS, or file transfer protocol with SSL security

FTP protocol

1. Name (required): Enter a unique name to the connection for easy reference.
2. Host (required): Enter the URI of the server host. For example: ftp.mycompany.com or 100.200.300.1.
3. Protocol (required): Choose the file transfer protocol (FTP, SFTP, or FTPS) for establishing the FTP connection.
4. Username (required): Enter the username for your account on the FTP server.
5. Password (required): Enter your password to log in to the FTP server.

SFTP protocol

Authentication key (PEM format) (optional): An SFTP connection can use a password or an authentication key to authenticate a user trying to connect to the SFTP server. Use this field to store the RSA private key used for authentication. It must be in PEM format. You can use a password, an authentication key, or both. We do not support keys with a passphrase so the SSH keys should always be generated without a passphrase. For more information, see Use SSH keys for SFTP connections.

FTPS protocol

Use implicit FTPS (optional): If the server supports Implicit FTPS (where the client and server always use an encrypted connection), check this box. Its default is Explicit.

Advanced settings

You can also configure the advanced settings fields.

1. Port (required): This field is set to default port numbers based on FTP, SFTP, and FTPS protocols. You can change this field to any port number to override the default value.
2. Use passive mode: This field is checked by default to use passive mode instead of active mode. If you want active mode instead, uncheck this box.
3. User directory is root (optional): This field is used if the relative path used by a file export or import is relative to your FTP login’s user directory or to the server root folder.
   • For example, suppose your files are located on the server at /usr/local/iio/files/download – if your FTP server account places you in your user directory after login (/usr/local/iio), then check this box and enter /files/download as your relative path. If you go straight to the server’s root directory (/) after login, then leave this box unchecked and provide /usr/local/iio/files/download as your relative path.
4. Entry parser (optional): This is an optional field and this field can be set if your FTP server is an uncommon type (not Windows or Linux), or it does not support the SYST command.
5. Use PGP encryption (optional): If you want to have cryptographic privacy and authentication, check this box. It’s used for signing, encrypting, and decrypting files, directories, and other types of data communication.

1. PGP public key: Specify a public key for use with PGP file transfers. If you set this field then all files imported from Celigo integrator.io will be encrypted with this public key during file upload. If you do not want to use PGP encryption in your FTP Import, then leave this field blank. The key must be in ASCII Armor format. This key size can be up to 4096 bytes.
2. PGP private key: Specify a private key for use with PGP file transfers. If you set this field then all files exported to IO will be decrypted with this private key during file download. If you do not want to use PGP decryption in your FTP Export, then leave this field blank. The key must be in ASCII Armor format. This key size can be up to 4096 bytes.
3. PGP passphrase: Specify the passphrase to use to generate and encrypt your PGP private key. Your private key is encrypted on your machine using a hash of your passphrase as the secret key. You'll use this passphrase to decrypt and use your private key. Make sure that it is easy for you to remember and difficult for others to guess. The best passphrases are relatively long and complex and contain a combination of upper and lowercase letters, numeric and punctuation characters. If you forget your passphrase, you won't be able to decrypt your PGP private key.
4. Use custom PGP encryption algorithm (optional): The encryption algorithm PGP will secure your files. You choose from these algorithms:
   • AES-256
   • AES-192
   • AES-128
   • 3DES
   • CAST5

Require socket reuse (optional): When we select the protocol as FTPS in advanced settings, we see an extra field called Require socket reuse. By default, FTPS servers are configured to use two sockets on two different ports for connections. If your FTPS server uses only one port for FTPS traffic you can check this optional box to tell Celigo integrator.io to reuse one socket to connect to this one port.

Concurrency level (optional): Set this field to limit the number of concurrent/parallel requests allowed by the connection at any one time. By default, the connection will send data as quickly as possible. The FTP connection’s Concurrency level applies only to downloading files during export. All files uploaded to an FTP server during an import are sent one at a time.

Test and save the connection

Once you are done with configuring all the required fields, click Test connection to verify if the connection is successful, and then save the connection.
