  1. Open HST Server with root privileges.
  2. Click Configuration > Global > Transfer Server.

    Bring up the Server Configuration window

    Transfer Server configuration options.

  3. Edit settings on the Transfer Server tab. Select Override in the option's row to set an effective value.

Transfer Server Settings Reference

Setting Description Values Default
Address The network interface address on which the transfer server listens. The default value of 127.0.0.1 enables the transfer server to accept transfer requests from the local computer. If you set the address to 0.0.0.0, the transfer server can accept requests on all network interfaces. Alternatively, a specific network interface address may be specified. Valid IPv4 address 127.0.0.1
Port The port on which the transfer server accepts transfer requests. Positive integer 1 - 65535 40001
Persistent Storage Enable to retain data that is stored in the database between reboots of asperacentral. Enable or Disable Enable
Persistent Storage Path The location in which to store data between reboots of asperacentral. If the path is a directory, then a file is created with the default name central-store.db. Otherwise, the file is named as specified in the path. Valid system path If the application is installed in the default location, then the path is the following:

/opt/aspera/var/

Maximum Age (seconds) Maximum allowable age (in seconds) of data to be retained in the database. Positive integer 86400
Exit Central on Storage Error The behavior of the asperacentral server if a database write error occurs. Ignore or Exit Ignore
Compact Database on Startup Enable or disable compacting (vacuuming) the database when the transfer server starts. Enable or Disable Enable
Files Per Session The maximum number of files that can be retained for persistent storage. Positive integer 1000
Ignore Empty Files Set to true to block the logging of zero-byte files. true or false true
Ignore No-transfer Files Set to true to block the logging of files that were not transferred because they exist at the destination. true or false true
Post-Transfer Validation Timeout How many seconds to wait for a post-transfer validator to update the status of a file before the file is released from the validator and its status is changed back to "to_be_validated". This allows a file to be validated by a different validator if the first validator stops working.
