Name:

listenPortFileName

Scope:

input

Type:

word

Default:

none

Required?:

no

Introduced:

Description

When port="0" is configured, the operating system selects an available UDP port for the imdtls listener. listenPortFileName writes that selected port number to the named file after the socket is bound.

This is primarily useful for tests and automation that must avoid preselecting a port before the listener starts.

Input usage

module(load="imdtls")
input(type="imdtls" port="0" listenPortFileName="imdtls.port")
