This chapter describes the file distribution services on the NIOS appliance. It contains the following sections:


File Distributio n Overview
You can upload files to the NIOS appliance and to individual Grid members using TFTP, HTTP, and FTP, clients. You can also upload files using the Grid Manager web interface or the API. Using access control lists, you can specify which network devices can upload files or retrieve files. You can use the Group Results function for file distribution services (TFTP, FTP, and HTTP) to group members by extensible attributes that contain the same values. For information about how to group members by extensible attributes, see Grouping Members by Extensible Attributes.


Note: File distribution services using TFTP, HTTP, and FTP is not supported by IPv6-only appliances.


Network devices, such as VoIP phones, can use the DHCP services on the appliance for IP address assignments and use the file distribution services for IP device configuration downloads. Downloads can be accomplished with TFTP, HTTP, or FTP.

34The appliance checks if it is allowed to respond to the request from the client.
If the client is on the access control list as allowed to upload and retrieve files, the appliance accepts the request. If the client is not on the access control list or is on the list of denied clients, the appliance does not allow the client to upload or retrieve the file.
File uploads and downloads by FTP and TFTP file distribution clients are logged in the syslog under the Administration
-> Logs tabs. The logs store the following information:

  • Client IP
  • Date and Time
  • Event type
  • File(s) downloaded and/or uploaded
