+/*!
+The IPC server listens on localhost. The IPC client runs on both the
+client/server process or the GUI. The IPC server runs on the daemon process.
+This allows the GUI to send config changes to the daemon and client/server,
+and allows the daemon and client/server to send log data to the GUI.
