Avoid "Unable to read from network interfaces. Requires read permissions"?

Hello Wolfram Community,

I'm trying to use WL NetworkPacketCapture functions in a Mathematica Notebook and in this particular case I'm getting an error for which I'm required to "elevate permissions" on my Mac. The problem is I can't find any documentation on how to do so. Any ideas?

Unlike, say Cloud permissions, this is low level system permissions. Any links to documentation would be highly appreciated.

"Unable to read from network interfaces. Requires read permissions for devices /dev/bpf"


Hi Jose, if you are on OS X then fire up a terminal and enter

sudo chmod o+r /dev/bpf*

which gives you (BUT also everybody else with an account on the machine the necessary permission). There are more elaborate schemes with permission just for your account and persistent between logins which you can google e.g. by combining the search string above in combination with your OS and wireshark.
