What steps will reproduce the problem?

The code is here.
http://jan.newmarch.name/go/rpc/chapter-rpc.html

ArithServer and ArithClient


/**
* ArithServer
 */

package main

import (
    "fmt"
    "net/rpc"
    "errors"
    "net/http"
)

type Args struct {
    A, B int
}

type Quotient struct {
    Quo, Rem int
}

type Arith int

func (t *Arith) Multiply(args *Args, reply *int) error {
    *reply = args.A * args.B
    return nil
}

func (t *Arith) Divide(args *Args, quo *Quotient) error {
    if args.B == 0 {
        return errors.New("divide by zero")
    }
    quo.Quo = args.A / args.B
    quo.Rem = args.A % args.B
    return nil
}

func main() {

    arith := new(Arith)
    rpc.Register(arith)
    rpc.HandleHTTP()

    err := http.ListenAndServe(":1234", nil)
    if err != nil {
        fmt.Println(err.Error())
    }
}



/**
* ArithClient
 */

package main

import (
    "net/rpc"
    "fmt"
    "log"
    "os"
)

type Args struct {
    A, B int
}

type Quotient struct {
    Quo, Rem int
}

func main() {
    if len(os.Args) != 2 {
        fmt.Println("Usage: ", os.Args[0], "server")
        os.Exit(1)
    }
    serverAddress := os.Args[1]

    client, err := rpc.DialHTTP("tcp", serverAddress+":1234")
    if err != nil {
        log.Fatal("dialing:", err)
    }
    // Synchronous call
    args := Args{17, 8}
    var reply int
    err = client.Call("Arith.Multiply", args, &reply)
    if err != nil {
        log.Fatal("arith error:", err)
    }
    fmt.Printf("Arith: %d*%d=%d\n", args.A, args.B, reply)

    var quot Quotient
    err = client.Call("Arith.Divide", args, &quot)
    if err != nil {
        log.Fatal("arith error:", err)
    }
    fmt.Printf("Arith: %d/%d=%d remainder %d\n", args.A, args.B, quot.Quo, quot.Rem)

}


What is the expected output?
just no error message
