Random Array with no repeated numbers

So what I am trying to do is create a random array of 5 elements, those elements should be filled with numbers from 1 to 6 and they shall not repeat, I can't tell where my logic is wrong.

void genNumber(int vet[]){
int max, i, j, atual;
srand(time(NULL));

max = 7;
for (i=0;i<5;i++){
    vet[i] = rand() % max;
    while(vet[i] == 0){
        vet[i] = rand() % max;
    }

    for(j=0;j<i;j++){
        atual = vet[j];
        while((vet[i] == atual)||(vet[i] == 0)){
            vet[i] = rand() % max;
            atual = vet[j];
        }
    }
}
}
