+#!/usr/bin/env python3
+"""UDP syslog receiver for Turnstone cluster monitoring.
+
+Listens on UDP port 5140 (non-privileged) and appends received messages
+to /devl/turnstone-cluster/data/network-syslog.txt for the Turnstone
+live watcher to tail.
+
+Each line written is:
+  <source_ip> <raw_syslog_message>
+
+This preserves the original syslog content while adding the sender IP so
+Turnstone's syslog ingestor can tag entries by device.
+
+Usage:
+  python3 syslog_receiver.py [--port 5140] [--output /path/to/network-syslog.txt]
+
+Installed as: turnstone-syslog-receiver.service (see adjacent .service file)
