How to properly seed random number generator

Question

I am trying to generate a random string in Go and here is the code I have written so far:

package main

import (
    \"bytes\"
    \"fmt\"
    \"math/rand\"

Small update due to golang api change, please omit .UTC() :

time.Now().UTC().UnixNano() -> time.Now().UnixNano()

import (
    "fmt"
    "math/rand"
    "time"
)

func main() {
    rand.Seed(time.Now().UnixNano())
    fmt.Println(randomInt(100, 1000))
}

func randInt(min int, max int) int {
    return min + rand.Intn(max-min)
}
