Talk:Cron

Hello. My name is Grey, I am a beginner with Alpine Linux. I would like to know how I can change mac address on my PC running alpine linux 3.22 std. In Debian, I open the terminal and type "sudo crontab -e", I go to the bottom of the script and I add "@reboot macchanger -r wlan0", I save it, and when I reboot my PC, it changes mac address automatically. How can I do it in Alpine? Thank you very much for your kind help. Grey

Hi Grey, You can use the following command $ apk search Cmd:macchanger to find the package that contains the command of interest i.e macchanger-1.7.0-r3 . The output shows that the package name is macchanger and it can be installed using # apk add macchanger. Please refer to apk page for more info. In future, please consider using other Support channels like IRC etc... - Prabuanand (talk) 13:43, 15 September 2025 (UTC)

Hi Grey, if you don't want to add an extra apk to your system, and you are using ifupdown-ng (should be default these days), add the following pre-up command to your stanza for your wlan0 interface. For example:

 auto wlan0
 iface wlan0 inet dhcp
       .
       .
       .
       # **** To get our special mac addr *****
       pre-up ip link set $IFACE addr de:ad:be:ef:ca:fe
       .
       .
       .
       

Just another alternative.
