Set up Users and Groups
Aspera clients connect to HSTS by authenticating as a system user who is configured
in the application. The user can also belong to a group that is
configured in the application. Users and groups can be set
up by running asconfigurator commands or directly editing the configuration file,
aspera.conf .
Setting Up Transfer Users
HSTS uses system accounts to authenticate connections from Aspera clients. The system users must be added and configured as Aspera transfer users before clients can browse the server file system or run FASP transfers to and from the server. When creating transfer users, you can also specify user-specific settings, such as transfer bandwidth, docroot, and file handling. User configuration is an important part of securing your server.
Setting Up Transfer Groups
Transfer settings can be applied to your system's user groups. If users within a group do not have individual transfer settings, then the group's transfer settings are applied. HSTS doesn't create user groups on the operating system for you, so you must ensure that the groups exist before adding them to your Aspera product.
Configuration Precedence
HSTS applies configuration settings in this order: 1) user settings, 2) group settings (and if a user belongs to more than one group, precedence can be set for each group), 3) global settings, 4) default settings. User settings have the highest priority and default the lowest.
Setting Up a User's Public Key on the Server
Public key authentication is an alternative to password authentication, providing a more secure authentication method that allows users to avoid entering or storing a password, or sending it over the network. An Aspera client generates a key pair (a public key and a private key) on the client computer and provides the public key to the administrator of the remote Aspera transfer server. The server administrator sets up the client user's public key as described in the following steps.
Testing a User-Initiated Remote Transfer
Once you have configured an Aspera transfer user on HSTS , test that an Aspera client can successfully connect to HSTS and upload a file.
