Feature #4098
Updated by Davide Pesavento over 7 years ago
Currently, when `UdpFactory` creates a `UdpChannel`, the latter is put into listening mode unconditionally. This is different from e.g. `TcpChannel`, where listening or non-listening is decided by a configuration file setting (`face_system.tcp.listen`). This task implements a similar knob (`face_system.udp.listen`) that applies to for `UdpChannel`. The use case is allowing "outgoing-only" UDP channels, in which where UDP faces can only be created explicitly through management requests, and incoming datagrams from unknown peers are ignored.
