SFTP Subscriber

The SFTP subscriber receives notifications from topics and uploads files over a Secure Shell (SSH) connection to specified SSH File Transfer Protocol (SFTP) hosts.

Creating an SFTP Subscription

In the FME Flow Web User Interface, select Notifications > Subscriptions, and click New.

Move pointer over example to view:

• Name: Provide a name for the subscription.
• Protocol: Select SFTP.
• Topics Subscribed To – Specify the Topics you want to subscribe to using the drop-down selector. To create a topic and use it right away, click +.
• Host – The SFTP host name.
• Port – The SFTP port number. The default value is 22.
• Username – The SFTP user name for authentication.
• Password – The SFTP user password for authentication.
• Verify Host Keys– Choose whether or not to verify the host key for the server being connected to.
• Path to Known Hosts File – If Verify Host Keys is Yes, specify the path to the known_hosts file that contains the public keys for any servers you wish to connect to. If the known_hosts file is saved to a Resources directory, click the ellipsis (...) and select the file. Otherwise, enter the file path directly. File paths must use forward slashes (/) or escaped backslashes (\\).
Note  A known_hosts file contains public keys for computers you connect to via SSH. To obtain a public key and insert it into the known_hosts file, run the following command in OpenSSH: ssh-keyscan -t rsa <hostname> > <path_to_known_hosts_file>. Alternatively, contact your system administrator.
