SFTP server configuration properties

For each runtime environment that uses the File Integration Service, you can configure an SFTP server to exchange files.

You configure SFTP server properties on the SFTP Server tab of the File Server for agent page. Configure the following types of properties:

•General properties
•Algorithms properties
•Host keys properties
•Upload restriction properties

General properties

The following table describes general SFTP server properties:

Property	Description
Enable SFTP Server	Whether to enable the SFTP server. When not enabled, the SFTP server cannot receive or send files. Default is disabled.
Port	Port number for the SFTP server. Default is 15002.
Local Address	Local IP address for the SFTP sever.
Enable SCP	Whether to use session control protocol (SCP) to create the connection. Default is disabled.
Idle Timeout	Number of seconds that the connection is idle before is closes. Default is 300.
Maximum Logins	Maximum number of users that can be logged in to the server concurrently. Default is 500.
Login Failure Delay	Delay between failed login attempts, in seconds. Default is 0.
Maximum Login Failures	Number of allowed login failures for a user. Default is 5.
Welcome Message	Message to show when the connection to the server is established.

Algorithms properties

Enable the following algorithm types in the Algorithms section of the SFTP Server tab:

•Cipher algorithms
•Message Authentication Code (MAC) algorithms
•Compression algorithms
•Key exchange algorithms

When you configure the use of algorithms for SFTP file exchange, consider the following rules and guidelines:

•You can move algorithms between the Available and Selected lists. The File Integration Service applies the algorithms that are listed in the Selected list.
•If no algorithms are selected for an algorithm type, the File Integration Service applies all the algorithms that are listed in the Available list.
•The File Integration Service applies the algorithms in the order in which they are listed, from the top of the list to the bottom of the list. You can use the up and down arrows to change the order of the algorithms in list.

Host keys properties

The following table describes host keys properties:

Property	Description
RSA Key File Location	Location of the RSA host key file.
RSA Key Passphrase	Passphrase for the RSA key.
DSA Key File Location	Location of the DSA host key file.
DSA Key Passphrase	Passphrase for the DSA key.

Upload restrictions properties

You can specify the types of files to allow or deny in an SFTP file exchange. The following table describes the properties that control upload restrictions:

Property	Description
File Extension Filter Type	Whether to accept or deny the extensions in the File Extensions list. Use one of the following values: - Do Not Filter. Accept all file types. - Accept. Accept files with the extensions listed in the File Extensions property. - Deny. Do not allow files with the extensions listed in the File Extensions property. Default is Do Not Filter.
File Extensions	List of file extensions. Add the file extensions that correspond to the File Extension Filter Type. For example, to accept .csv and .txt files, in the File Extension Filter Type property, select Accept, and then add csv and txt to the list of file extensions. To add an extension to the list, type the extension in the text box and click Add. To remove an extension from the list, highlight the extension and click Delete.
File Extension Case Sensitive	Whether to factor case when you filter using the file extensions list. When enabled, files with extensions that do not match the case used in the File Extensions list cannot be uploaded. For example, if the file extension list includes csv but not CSV, files with the extension of csv can be uploaded but files with the extension of CSV cannot be uploaded. Default is disabled.
Allow Files with No Extension	Whether to allow files that do not include the extension in the file name. Default is disabled.
Allow Files with Extension	Whether to enable the file extension filter. When enabled, the file extension properties configured on this page determine which file types can be uploaded. Default is enabled.
