Inside Haiku's Network Stack: Interfaces, Protocol Modules, and Userland Services
A system-level view of Haiku networking and why hardware drivers, protocol modules, DHCP, DNS, and applications fail in different layers.
Haiku networking combines kernel interfaces and protocol modules with drivers and userland services. An interface can exist while DHCP fails; an address can work while DNS does not; a browser failure may be TLS or WebKit rather than the network stack.
Troubleshooting should move upward: verify device/driver, link, address and routes, DNS, then application behavior. Packet capture and logs are more reliable than repeatedly toggling the interface.
Compatibility work often adapts driver code while preserving Haiku’s own kernel and device model. Calling the whole stack “a BSD port” hides the integration and native APIs required to make networking behave as a Haiku subsystem.
