I recommend you not to run it automatically, unless you really need to change the MAC id every time. To change the MAC address of enp0s3 network card, run:. Finally, to return the MAC address to its original, permanent hardware value, run the following command:. Once you reboot the system, the changes will be automatically lost, and the actual MAC address will be restored again. As you can see, both methods are pretty easy.
Choose any one that works for you. To revert back to the original MAC address, simply reboot your system.

There are numerous tools that will do this for you. Fint, ya see there is where the problem lies Incidentally, does anyone know if there is an arp parameter to delete the entire table in Linux Broadcast pinging does not seem to send arp requests so does not populate the arp table. Frennzy, ok I think I got it, thanks. Pinging does populate the arp table, so if I ping sweep, I would be pinging every address, whether there is a device associated or not. After this I should have an arp table to parse through looking for my MAC address Now to implement this and see if I can egt this to work from a script BTW: the script is python using pexpect quote: There are numerous tools that will do this for you.
Could you name one that is included with most Linux distributions? Nmap Or, you could write your own shell script to sweep a given subnet with pings, shouldn't be that difficult. Google is really hot on fping, so am I.
You can change the fping output easily so it only gives you up or down hosts. Sometimes slower Ok I've started using fping ex: fping -c 1 -g After this I do an arp, which gives me all the addresses, incomplete and complete, not in order.

So, I'm trying to do a pexpect for "ether" which is the HWtype of the "completed" addresses. It seems messy The man pages don't seem too much help, or maybe I missed it. Thanks for the help so far I'm getting there EDIT: there seems to be a timer after which the incomplete entries are removed from the table Just to share with the community Here's what I have in my script and it works If anyone sees any major issues, please let me know.
Thanks to all who helped me accomplish this task.
