Configuring the IBM Aspera NodeD Service

The IBM Aspera NodeD Service handles HTTP/HTTPS requests to HST Server. You can configure server settings

including the hostname, HTTP/HTTPS ports, the address and port of the Redis database, and SSL certificates.

Configuration Methods

The server can be configured for the Node API by using the asconfigurator command-line tool or by editing the

<server> section of aspera.conf:

•

Asconfigurator: Use the following syntax, substituting option with the option from the following table and value

with the desired value:

# /opt/aspera/bin/asconfigurator -x "set_server_data;option,value"

To view the current settings, run the following command:

# /opt/aspera/bin/ asuserdata -a

• Aspera.conf: Open it in a text editor with administrative privileges from the following location:

/opt/aspera/etc/aspera.conf

See the sample aspera.conf following the table.

After manually editing aspera.conf, validate your XML by running the following command:

# /opt/aspera/bin/asuserdata -v

Node API Configuration Options

Important configuration considerations:

• Certain services must be restarted for changes in the settings to take effect, as described in the To Activate

Changes column. The commands to restart these services are given following the table.

• In addition to the Aspera server configuration, if you plan to transfer many small files with the Node API, you

might need to increase the number of file descriptors available on your system. If too few descriptors are available,

the Redis database and the transfer fail. For instructions, see Node API Transfers of Many Small Files Fails on

page 332.
