[fedorchikthebest]

if ((conn = sam3StreamConnect(ses, line)) == NULL) {
            fprintf(stderr, "ERROR: can't connect: %s\n", ses->error);
            return 1;
}
sleep(1);
rb[2] = 10;
char test[5] = {1, 2, 3, 4, 5};
printf("%d\n", sam3tcpSend(conn->fd, test, 5));

This is not a server problem because when sending the same data using a socs proxy. It comes correctly
