The tcp_listen call should be change like this: ptel_pcb = tcp_listen(ptel_pcb);
Because the ptel_pcb is freed, and a "listen pcb" is return, and it's not the same one. In last CVS head "rawapi.txt" you can read : "- struct tcp_pcb *tcp_listen(struct tcp_pcb *pcb) Commands a pcb to start listening for incoming connections. When an incoming connection is accepted, the function specified with the tcp_accept() function will be called. The pcb will have to be bound to a local port with the tcp_bind() function. The tcp_listen() function returns a new connection identifier, and the one passed as an argument to the function will be deallocated. The reason for this behavior is that less memory is needed for a connection that is listening, so tcp_listen() will reclaim the memory needed for the original connection and allocate a new smaller memory block for the listening connection. tcp_listen() may return NULL if no memory was available for the listening connection. If so, the memory associated with the pcb passed as an argument to tcp_listen() will not be deallocated." ==================================== Frédéric BERNON HYMATOM SA Chef de projet informatique Microsoft Certified Professional Tél. : +33 (0)4-67-87-61-10 Fax. : +33 (0)4-67-70-85-44 Email : [EMAIL PROTECTED] Web Site : http://www.hymatom.fr ==================================== P Avant d'imprimer, penser à l'environnement -----Message d'origine----- De : [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] De la part de wll Envoyé : jeudi 8 novembre 2007 19:32 À : Lwip Users Objet : [lwip-users] telnet server Hi all, I'm using the lwip-1.1.1 with raw api, and I want to make a telnet server. My init function is: void Telnet_init(void) { struct tcp_pcb *ptel_pcb; //new pcb ptel_pcb = tcp_new(); //Bind it to port 23 tcp_bind(ptel_pcb, NULL, 23); //state to pcb LISTEN tcp_listen(ptel_pcb); //register the callback tcp_accept(ptel_pcb, Telnet_accept); } But the code in the callback Telnet_accept never run. Looking in the stack I saw that the function tcp_input() call to tcp_listen_input(), but the last one do esn't call to tcp_process(). Can someone wive me an advice, regards Med __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
