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
page 332.
