Types

type Sniffer

type Sniffer struct {
	Timeout       time.Duration
	RewriteDomain bool // Whether to rewrite the address even when it's already a domain
	TCPPorts      utils.PortUnion
	UDPPorts      utils.PortUnion
}

Sniffer is a server core RequestHook that performs packet inspection and possibly rewrites the request address based on what's in the protocol header. This is mainly for inbounds that inherently cannot get domain information (e.g. TUN), in which case sniffing can restore the domains and apply ACLs correctly. Currently supports HTTP, HTTPS (TLS) and QUIC.
