Network

Network IP, port, and socket buffer settings.

The Network configuration options can be found in the application's Configuration, under the Global, and Users tabs.

Bring up the Server Configuration window

Network configuration options.

The following table explains all configuration options:

Field 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 127.0.0.1) 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
Server UDP Port reuse Allow or disallow different processes to reuse the same UDP port at the server. By default, reuse is allowed (true).
  • true
  • false
true
Disable Packet Batching When set to true, 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
  • false
false
Maximum Socket Buffer (bytes) Upper bound 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 Enable auto correction of base (minimum) RTT measurement. This feature is helpful for maintaining accurate transfer rates in hypervisor-based virtual environments.
  • true
  • false
false
Reverse path congestion inference Enable reverse path congestion inference, where the default setting of "true" prevents 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
  • false
true
