Network configuration

The Network configuration options include the network IP, port, and socket buffer settings.

  1. Open the application with Administrator privileges.
  2. Click Configuration > Network.

    Bring up the Server Configuration window

    Network configuration options.

  3. Edit Global , Groups, and Users settings on their Network tabs. Select Override in the option's row to set an effective value. User settings take precedence over group settings, which take precedence over global settings.

Option Description Values Default
Bind IP address Specify an IP address for server-side ascp to bind its UDP connection. If a valid IP address is given, ascp sends and receives UDP packets only on the interface corresponding to that IP address.
Important: The bind address must be only modified (changed to an address other than 127.0.0.1) if you, as the System Administrator, understand the security ramifications of doing so, and initiated precautions to secure the SOAP service.
valid IPv4 address None specified
Bind UDP port Prevent the client-side ascp process from using the specified UDP port. When configured the server-side, ascp process tells ascp clients to send UDP data to this port. integer in the range 1024 - 65535 33001
Disable Packet Batching Set to true to send data packets back-to-back (no sending a batch of packets). Resulting in a smoother data traffic at a cost of higher CPU usage. true or false false
Maximum Socket Buffer (bytes) Set the upper bound of the UDP socket buffer of an ascp session below the input value. The default of 0 causes that the Aspera® sender uses its default internal buffer size, which might be different for different operating systems. positive integer 0
Minimum Socket Buffer (bytes) Set the minimum UDP socket buffer size for an ascp session. positive integer 0
RTT auto correction Set to true to enable auto correction of the base (minimum) RTT measurement. This feature is helpful for maintaining accurate transfer rates in hypervisor-based virtual environments. true or false true
Reverse path congestion inference Set to true to prevent the transfer speed of a session from being adversely affected by congestion in the reverse (non data-sending) transfer direction. This feature is useful for boosting speed in bidirectional transfers. true or false true
