Hi, I have a little tutorial to be able to connect to a Cisco device via the console port (tested on my computer with Parrot OS and a Cisco ASA 5505). To start, you need an RJ45-DB9 console cable (if your PC does not have a DB9 port you can buy a USB-> DB9 adapter where you will reread the RJ45-DB9 console cable). Then you have to install through the APT package manager “screnn”, then once the screnn package is installed you have to connect the console cable to your computer and type “sudo dmesg | grep -i tty” to determine the cable port. Once identified, you can connect in console on your Cisco device using the “screen / dev / tty $ YourPort” command and type Enter. You will then have a command prompt for your Cisco device on Parrot OS.
