We're born alone, we live alone, we die alone. Only through our love and friendship can we create the illusion for the moment that we're not alone. — Orson Welles. Hi guys, if you ever check your task manager you’ll notice chrome is listening to port 5353 on Linux.

In order to disable this Chrome functionality you need to first create a directory and policy file. You could do this by executing the command below. sudo mkdir -p /etc/opt/chrome/policies/managed/ sudo touch /etc/opt/chrome/policies/managed/block_mdns_ssdp.json What this does is first create a directory inside the /etc/opt/chrome which will be used to store manage policies and create the initial policy file that we would be editing. Then we edit the block_mdns_ssdp.json file that we created earlier and then we put the contents
