Hello, im ussing a beaglebone black ,i have put an interface in monitor mode and the program has executed. i get the following error bash: ./sniff-probes.sh: Permission denied

It sounds like your sniff-probes.sh file doesn't have execute permissions. You can add them with:

chmod +x sniff-probes.sh

Oh man, I remember coming across this ages ago. If I remember correctly, some OSes have distributions of awk that vary slightly. I've confirmed that this script works with gawk. Perhaps try downloading gawk and changing awk in sniff-probes.sh to gawk.

I'm pretty sure that Ubuntu/debian ship with gawk as the default awk implementation. What OS are you on?

If that fixes your problem I'll update this repo to specifically use gawk.

My OS is debian ,i'll try this thanks

I can confirm that my awk (and the awk on the Ubuntu machine that I developed this on) actually points to gawk :open_mouth:. Have gawk a go ;)
