Why PNETLab 5.3.1.1 Stands Out

• Fix: In version 5311, ensure the Docker interface is set to "Management (Cloud)" network, not "VirtIO." This is a common oversight.

• Issue: Nodes fail to start (Error: Permission denied).
• Connect Nodes:

  Example short configuration (bridged lab)

  • Create bridge:

    sudo nmcli connection add type bridge ifname br-lab con-name br-lab
    sudo nmcli connection modify br-lab ipv4.addresses 192.168.100.10/24 ipv4.method manual
    

  • Start pnetlab, upload images to /opt/pnetlab/images, set permissions:

    sudo chown -R pnetlab:pnetlab /opt/pnetlab/images
