How to Change MAC Address

Prerequisites

Before changing MAC address, make sure you have:

• SSH access to your VPS
• Root or sudo privileges

Step 1: Check Current MAC Address

Connect to your VPS:

ssh hxroot@YOUR_SERVER_IP -p 22

ip link show eth0

Step 2: Temporarily Change MAC Address

Bring interface down:

sudo ip link set dev eth0 down

Set new MAC (replace with desired MAC):

sudo ip link set dev eth0 address 02:01:02:03:04:05

Bring interface up:

sudo ip link set dev eth0 up

Step 3: Verify Change

ip link show eth0 | grep ether

Step 4: Make Permanent (Systemd Network)

sudo nano /etc/systemd/network/10-eth0.link

Add:

[Match]
MACAddress=old_mac_address

[Link]
MACAddressPolicy=none
MACAddress=02:01:02:03:04:05

Reboot to apply.

Alternative: Using netplan (Ubuntu)

sudo nano /etc/netplan/01-netcfg.yaml

Add:

ethernets:
  eth0:
    macaddress: 02:01:02:03:04:05
