What did you do?
i have write a server use go and disable keepalive, and then i write a client use go to connect this server, why i use wireshark to capture package still capture tcp keepalive package? is disable keepalive do not work?
server code:
listenner, err := net.ListenTCP("tcp", &net.TCPAddr{ Port: port, }) if err != nil { panic(err) } for { conn, err := listenner.AcceptTCP() if err != nil { fmt.Printf("accept error: %s \n", err) continue } conn.SetKeepAlive(false) n, err := conn.Write([]byte("You are welcome. I'm server.")) if err != nil { log.Printf("write datat to client error: %s \n", err) continue } log.Printf("write %d bytes \n", n) }
client code:
`conn, err := net.Dial("tcp", addr)
if err != nil {
fmt.Println("dial failed:", err)
os.Exit(1)
}
defer conn.Close()
buffer := make([]byte, 512)
for {
n, err := conn.Read(buffer)
if err != nil {
fmt.Println("Read failed:", err)
return
}
fmt.Println("count:", n, "msg:", string(buffer))
}`
What did you expect to see?
wireshark do not capture tcp keepalive package
