To set the Network configuration options, including the network IP, port, and socket buffer settings, click Configuration and modify values for the Global, Groups, and Users under their respective Network tabs. Select Override in the option's row to set an effective value.

Bring up the Server Configuration window

Network configuration options.

The following table explains all configuration options:

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 should only be modified (changed to an address other than if you, as the System Administrator, understand the security ramifications of doing so, and have undertaken precautions to secure the SOAP service.
valid IPv4 address blank
Bind UDP Port Prevent the client-side ascp process from using the specified UDP port. integer between 1 and 65535 33001
Disable Packet Batching Set to true to send data packets back-to-back (no sending a batch of packets). This results in 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 will cause the Aspera sender to use its default internal buffer size, which may 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 false
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 bi-directional transfers. true or false true
