Hi,
I'm trying to create a comunication between a client and an echo server;
but there is a behaviour of the server that I don't understand, the packet of
the connection request from the client is dropped when is received from the
server, it seems that the packet isn't for the server.
That is what I wrote in my programs:
/* for the client */
...
mem_init();
memp_init();
pbuf_init();
netif_init();
ip_init();
tcp_init();
printf("stack TCP/IP initializzato.\n");
IP4_ADDR(&GateWay, 192,168,0,2);
IP4_ADDR(&IP, 192,168,0,1);
IP4_ADDR(&NetMask, 255,255,255,0);
netif_add(&Net, &IP, &NetMask, &GateWay, NULL, clientif_init, ip_input);
netif_set_default(&Net);
cli_init(pcb);
...
void cli_init(struct tcp_pcb *pcb)
{
struct ip_addr IPDest;
IP4_ADDR(&IPDest, 192, 168, 0, 2);
pcb = tcp_new();
tcp_connect(pcb, &IPDest, 5000, &cli_connected);
}
...
/* for the server */
...
mem_init();
memp_init();
pbuf_init();
netif_init();
ip_init();
tcp_init();
printf("stack TCP/IP initializzato.\n");
IP4_ADDR(&GateWay, 192,168,0,1);
IP4_ADDR(&IP, 192,168,0,2);
IP4_ADDR(&NetMask, 255,255,255,0);
netif_add(&Net, &IP, &NetMask, &GateWay, NULL, serverif_init, ip_input);
netif_set_default(&Net);
srv_init();
...
void srv_init(void)
{
struct tcp_pcb *pcb;
pcb = tcp_new();
tcp_bind(pcb, IP_ADDR_ANY, 5000);
pcb = tcp_listen(pcb);
tcp_accept(pcb, srv_accept);
}
...
I don't understand where is the error, there is someone that can help me?
thanks.
