Initial EVE-NG Configuration

These are some initial commands that might be useful for setting up your EVE-NG environment.

# Update package lists
sudo apt update

# Fix permissions issues within the EVE-NG lab directory
sudo /opt/unetlab/wrappers/unl_wrapper -a fixpermissions

# Transfer files from your host machine to the virtual machine (VM) where EVE-NG is installed
scp some-file.zip root@192.168.1.100:/root/

Image Placement in EVE-NG

Place the downloaded image files in the following directories within your EVE-NG VM:

• .image and .image.md5sum files (for Dynamips-based routers): /opt/unetlab/addons/dynamips/
• .bin files (for IOU - IOS on Linux): /opt/unetlab/addons/iol/bin/
• .qcow2 files (for Qemu-based VMs like Linux nodes and modern Cisco devices): /opt/unetlab/addons/quemu/<respective_file_name>/ (create the subdirectory if it doesn't exist)

Important

After adding new images, you might need to fix permissions again.

Initial Pnetlab Configuration

Use ishare2 from this url: https://github.com/ishare2-org/ishare2-cli

apt update

# Install ishare2
wget -O /usr/sbin/ishare2 https://raw.githubusercontent.com/ishare2-org/ishare2-cli/main/ishare2 && chmod +x /usr/sbin/ishare2 && ishare2

# try upgrade ishare2 and pnetlab.
ishare2 upgrade

How to Execute Python Scripts

These steps outline how to set up a virtual environment and run Python scripts (like those using Netmiko) on a Linux node within EVE-NG.

# Create a virtual environment named 'venv'
python3 -m venv venv

# Activate the virtual environment
source venv/bin/activate.fish

# Install the Netmiko library
pip install netmiko

# Run your Python script
python -m chapter-6.01

# Deactivate the virtual environment when you're done
deactivate
