Can i use FTP and TCP Socket in parallel?

Hello,

i am running a FTP Server on my K60 board .. with MQX3.8 ..

All is fine!

Then in another project i used a TCP Socket for some communication ..

Now i want to merge this 2 projects .. but both together don't work..

If the TCP socket is listening the FTP don't work correctly.. i can connect but not more .. "LIST" hangs up ..

now i removed the RTCS_selectall();

and the ftp is running correct, but my socket does not connect ..

here is my socket listen task ..

when i try to connect via telnet comes the error message "connection refused" ..

accept return every time RTC_SOCKET_ERROR ..

void server_task (uint_32 initial_data) { sockaddr_in     laddr; uint_32      sock, listensock; int_32      error; uint_16      remote_addr_len; sockaddr_in     remote_addr = {0}; uint_32      value; boolean      connected=FALSE; boolean      opt_bool_value; _time_delay(100); #if (WITH_SOCKET_SERVER_TASK_DEBUG==1) printf("\nstart server_task !\n");#endif  laddr.sin_family      = AF_INET; laddr.sin_port        = SOCKET_SERVER_PORT; laddr.sin_addr.s_addr = INADDR_ANY; listensock = socket(PF_INET, SOCK_STREAM, 0); printf("STATE: %x\n", ((SOCKET_STRUCT_PTR)listensock)->STATE); if (listensock == RTCS_SOCKET_ERROR) {  printf("can't create socket ..\n");  error = RTCSERR_OUT_OF_SOCKETS; } value = 256; error=setsockopt(listensock, SOL_TCP,OPT_TBSIZE,&value,sizeof(value)); if (error) { printf("something failed..1!\n"); } error=setsockopt(listensock, SOL_TCP,OPT_RBSIZE,&value,sizeof(value)); if (error) { printf("something failed..2!\n"); }  opt_bool_value=TRUE; error=setsockopt(listensock, SOL_TCP,OPT_RECEIVE_NOWAIT,&opt_bool_value,sizeof(opt_bool_value)); if (error) { printf("something failed..3!\n"); } error = bind(listensock, &laddr, sizeof(laddr)); printf("STATE: %x\n", ((SOCKET_STRUCT_PTR)listensock)->STATE);  if (!error) {  error = listen(listensock, 0); } else {  printf("something failed..4!\n"); }  sock=RTCS_SOCKET_ERROR; printf("socket init done!\n"); printf("STATE: %x\n", ((SOCKET_STRUCT_PTR)listensock)->STATE); for (;;) {  connected=FALSE;  while (connected==FALSE) {   #if (WITH_SOCKET_SERVER_TASK_DEBUG==1)   printf("wait for connection..\n");   #endif      _time_delay(1000);      /*   //sock = RTCS_selectall(0);   sock=RTCS_selectset(&listensock, 1, 500);      if (sock == listensock) {    connected=TRUE;   } else {    #if (WITH_SOCKET_SERVER_TASK_DEBUG==1)||1    printf("no.. %x != %x\n", sock, listensock);    #endif    continue;   }   */   // Connection requested; accept it      remote_addr_len = sizeof(remote_addr);   printf("STATE: %x\n", ((SOCKET_STRUCT_PTR)listensock)->STATE);   printf("try to accept socket.. sock: %x, listensock: %x\n", sock, listensock);   sock = accept(listensock, &remote_addr, &remote_addr_len);   printf("accepted socket! sock: %x, listensock: %x\n", sock, listensock);   connected=TRUE;   if (sock==RTCS_SOCKET_ERROR) {    shutdown((uint_32)listensock, FTPDCFG_SHUTDOWN_OPTION);    connected=FALSE;   } else {    #if (WITH_SOCKET_SERVER_TASK_DEBUG==1)    printf("remote addr: %d.%d.%d.%d : %d connected\n",      (remote_addr.sin_addr.s_addr >> 24) & 0xFF,      (remote_addr.sin_addr.s_addr >> 16) & 0xFF,      (remote_addr.sin_addr.s_addr >> 8) & 0xFF,      remote_addr.sin_addr.s_addr & 0xFF,      remote_addr.sin_port);    #endif   }  }  while (1) {   // do something with connection ..  }    shutdown(sock, FLAG_CLOSE_TX); }  printf("fatal error!\n");}

AAAAH !!

after some deep debuging into the mqx i found the problem ..

there was no free space in the socket partition .. and then i found the socket partition initialisation ..

and then i see this variable <_RTCS_socket_part_init> ..

set this variable before you create the RTCS and you can get more than 3 sockets ..

_RTCS_socket_part_init=10;error=RTCS_create();
