Title: Bonjour Settings and TCP Keepalive Configuration
Summary
This section discusses Bonjour service name configuration and TCP keepalive parameters. It covers the `bonjour_name` parameter, which specifies the Bonjour service name, defaulting to the computer name if left empty. It then moves on to TCP settings, describing the function of `tcp_keepalives_idle` (time after which a keepalive message is sent), `tcp_keepalives_interval` (retransmission interval for unacknowledged keepalive messages), and `tcp_keepalives_count` (number of unacknowledged keepalive messages before connection is considered dead). Default values and system-specific behavior (especially on Windows) are noted. These TCP parameters are ignored in sessions connected via Unix-domain sockets.
