7.8 The port-name Module

The port-name utility module provides one redefinable variable and one callable function:

port_names : table[port] of string

Maps TCP/UDP ports to names for the services associated with those ports. For example, 80/tcp maps to "http". These names are used by the conn analyzer when generating connection logs (See Generic Connection Analysis).

endpoint_id (h: addr, p: port): string

Returns a printable form of the given address/port connection endpoint. The format is either <address>/<service-name> or <address>/<port-number> depending on whether the port appears in port_names.
