Helper function to scan for HSFZ endpoints.

Example

>>> sockets = hsfz_scan("192.168.0.42")

Parameters:

ip – IPv4 address of target to scan
scan_range – Range for HSFZ destination address
src – HSFZ source address, used during the scan
timeout – Timeout for each request
verbose – Show information during scan, if True

Returns:

A list of open UDS_HSFZSockets
