Change mac

[xgonzalez]

I have a 6 u3 and I want to change the mac because I always get the same.
I have seen that there are people who change it in the boot.ini file and others the smsc95xx_mac_addr file, but I do not find any of the two.
Anyone know how to fix it?

Can you check "/etc/smsc95xx_mac_addr" file?

This question is a little old, but i'll answer.
You could use macchanger

macchanger -m b8:bc:1e:56:ff:f7 eth0

On systemd based OS like openSUSE Tumbleweed you could use oneshot service during boot.

Create file:
/etc/systemd/system/macaddress.service

Code: Select all

[Unit]
Description=Change eth0 MAC address
Before=network-pre.target
Wants=network-pre.target

[Service]
Type=oneshot
ExecStart=/sbin/ip link set dev eth0 address 3a:02:ee:65:33:01 

[Install]
WantedBy=network.target

Activate service with
$ sudo systemctl enable macaddress

To use system.d services you'll probably need to bring the NIC down first, then change the MAC, then bring the NIC up again. Easily done with ExecStart commands.
