I developed an application which contains a small http server.
my application is launched in the boot. If I kill it (with kill -9 for example), the http server port will be taken directly by another daemon(acsd from broadcom).
I tried the same behavior with drop-bear, but the problem is not reproduced. If I kill drop-bear the acsd does not take its port.
here after the code of my server:
void http_server_init(void)
{
struct sockaddr_in server;
int cr_port;
for(;;) {
cr_port = conf.port;
int i = (DEFAULT_PORT == cr_port)? 1 : 0;
//Create socket
cr_socket_desc = socket(AF_INET , SOCK_STREAM , 0);
if (cr_socket_desc == -1)
{
LOG (ERROR,"Could not open server socket, Error no is : %d, Error description is : %s", errno, strerror(errno));
sleep(1);
continue;
}
/* enable SO_REUSEADDR */
int reusaddr = 1;
if (setsockopt(cr_socket_desc, SOL_SOCKET, SO_REUSEADDR, &reusaddr, sizeof(int)) < 0) {
LOG (WARNING,"setsockopt(SO_REUSEADDR) failed");
}
//Prepare the sockaddr_in structure
server.sin_family = AF_INET;
server.sin_addr.s_addr = INADDR_ANY;
for(;;i++) {
server.sin_port = htons(cr_port);
//Bind
if( bind(cr_socket_desc,(struct sockaddr *)&server , sizeof(server)) < 0)
{
//print the error message
LOG (ERROR,"Could not bind server socket on the port %d, Error no is : %d, Error description is : %s", cr_port, errno, strerror(errno));
cr_port = DEFAULT_PORT + i;
LOG (INFO,"Trying to use another port: %d", cr_port);
continue;
}
break;
}
break;
}
LOG (INFO,"server initiated with the port: %d", cr_port);
}
What I'm doing wrong in my http server?
