NAME¶

udp_daemon - Command-line reference server for the WSJT-X UDP protocol.

SYNOPSIS¶

udp_daemon [OPTIONS]

DESCRIPTION¶

udp_daemon is a command-line reference implementation of a server for the WSJT-X UDP protocol. It discovers WSJT-X clients and prints their status, decodes, WSPR decodes, logged QSOs, and logged ADIF records. Its source also demonstrates how an external application can receive and respond to WSJT-X messages:

https://github.com/WSJTX/wsjtx/tree/master/UDPExamples

The daemon listens as a unicast server by default. To use multicast, specify a valid multicast group with --multicast-group and configure the same group and port in each WSJT-X instance under Settings → Reporting → UDP Server. Multicast permits multiple servers to receive the same WSJT-X messages. MAC-ambiguous IPv4 multicast group addresses are not supported.

Without --network-interface, a multicast server joins the loopback interface. Use --list-interfaces to find interface names and repeat --network-interface to join the group on one or more selected interfaces. Some systems may require a suitable multicast route before traffic can be delivered to sockets on the sending host.
