Why doesn't my Spartez SSH scanner work?

Dee Heffemm

I'm trying to get the Spartez SSH scanner working but getting the error below. I'm following the setup instructions here. Anyone know why this isn't working?

Thanks

Hi Dave,

I am one of the developers at Spartez - the vendor behind Asset Tracker.

It seems that the scanner fails because it is unable to retrieve MAC addresses of your network adapters.

To diagnose this, can you check what is the output of the following command:

ifconfig | grep 'ether' | grep -v '00:00:00:00:00:00' | awk '{print $2}'

If this command returns empty string, it means that your ifconfig command returns something unexpected. In this case, can you invoke just

ifconfig

and let me know what the result is?

And another question: are you scanning a Mac or a Linux computer?

Dee Heffemm

Ah, I see. There is no 'ether' on Linux for the MAC line in the ifconfig output. This works however:

# ifconfig | grep 'HWaddr' | awk '{print $5};'

Is there a switch to specify a Linux host?

Janusz Gorycki_zbokco

Actually, OS should have been automatically detected. Somehow I assumed wrongly that you are on a Mac. For Linux, the command used by default for scanning is this one:

ip link list | grep 'link/' | grep -v '00:00:00:00:00:00' | awk '{print $2}'

What does it do in your case?

Also - you can try using the --verbose option to see what the scanner is trying to do.

Dee Heffemm

Hrm..that works fine on the Linux host.

# ip link list | grep 'link/' | grep -v '00:00:00:00:00:00' | awk '{print $2}'
