Is there an easy way to get the permanent MAC Address using Go?
Every network adapter must have a MAC. A MAC is unique and permanent. It's embedded in each networking adapter by the manufacturer.
A MAC address can also be called a Physical Address. Read my post on how to find your MAC address if you don't know it. All MAC addresses are hard-coded into a network card and can never be changed.
First, open Command Prompt, PowerShell, or Windows Terminal. Then, type in the command getmac and press Enter on your keyboard. The getmac command outputs a list of all your network adapters and their MAC addresses, which you can check in the Physical Address column highlighted below.
The best Linux command to find MAC address is using “ ip link show ” command. All we need is to open the Terminal then type ip link show command in the prompt. The number in front of link/ether is the MAC address. This command will list the network interfaces along with their details which include interface status, MAC address, MTU size, etc.
Open the command prompt. Press the ⊞ Win + R keys and type cmd into the Run field. Press ↵ Enter to start the Command Prompt. In Windows 8, press ⊞ Win + X and select Command Prompt from the menu. Run GetMAC. At the command prompt, type getmac /v /fo list and press ↵ Enter.
Exist some method (like macchanger -s $interface ), where I can see my permanent MAC with virtual interface?? To get the smbios mac address you can use dmidecode. dmidecode dumps the boxes DMI table contents so all the systems hardware components, as well as serial numbers, and BIOS revisions.
Physical address is nothing but mac address. You can find it using getmac command as described above or you can also use ipconfig command for getting physical/mac address using command prompt. Can you give me solution for below error. I am using Windows 7 32 bit OS .
package main
import (
"fmt"
"log"
"net"
)
func getMacAddr() ([]string, error) {
ifas, err := net.Interfaces()
if err != nil {
return nil, err
}
var as []string
for _, ifa := range ifas {
a := ifa.HardwareAddr.String()
if a != "" {
as = append(as, a)
}
}
return as, nil
}
func main() {
as, err := getMacAddr()
if err != nil {
log.Fatal(err)
}
for _, a := range as {
fmt.Println(a)
}
}
