By default Tracy client will listen on all network interfaces. If you want to restrict it to only listening on the localhost interface, define the \texttt{TRACY\_ONLY\_LOCALHOST} macro.
By default Tracy client will listen on all network interfaces. If you want to restrict it to only listening on the localhost interface, define the \texttt{TRACY\_ONLY\_LOCALHOST} macro at compile time, or set the \texttt{TRACY\_ONLY\_LOCALHOST} environment variable to $1$ at runtime.
