Re: nping not working as intended

Hi Luis

Finally got around to doing this after 3 hours of shoveling snow. Norway
can be a bitch this time of year.

Anyway, adding the options did not help. Below is a short command line log,
where I highlighted the commands I sent. As you can see, the response is
underwhelming.

*root@HCG:/home/pi# nping -4 --icmp -e eth0 --source-mac

Do you have any ideas what is going on?
