Connecting your computer to a Cisco Devnet Sandbox Router

You can probably use the advice below for linux, but this is primarily for Mac OS X. I have no idea how this would work for windows however, some of this may be able to help if you're stuck not being able to connect.

Download Homebrew

Open terminal and paste the command below.

sudo /bin/bash -c "$(curl -fsSL"

Download Python 3

Paste the command below in terminal

sudo brew install python 3

Download Ansible

Paste the command below in terminal

sudo python3 -m pip install ansible

Download Paramiko

Download Cisco Anyconnect

Wait for an email that tells you that your sandbox is activated.

Copy the Anyconnect information from the email and use that in the Anyconnect VPN.

Try to SSH into the router.

Paste command into terminal
