The process of acquiring and "fixing" images is often the biggest hurdle for new users. Many users ask for "Download EVE-NG Images" specifically
/opt/unetlab/addons/), and often require fixing permissions using a specific script (/opt/unetlab/wrappers/unl_wrapper -a fixpermissions). For beginners, this Linux command-line work is daunting compared to the "next-next-finish" installation of other simulators.To build a legitimate lab, you need to extract images from your own software downloads. Here is where to get them legally:
| Vendor | Platform | Legal Source | | :--- | :--- | :--- | | Cisco | IOSv, IOSvL2, CSR1000v, XRv9k | Cisco Software Central (requires valid SmartNet or CCO login) | | Juniper | vMX, vSRX, vQFX | Juniper Download Center (requires support contract) | | Arista | vEOS | Arista Software Portal (free registration for evaluation) | | Palo Alto | PA-VM | Palo Alto Customer Support Portal (trial licenses available) | | Fortinet | FortiGate-VM | Fortinet Developer Network (trial NFR licenses) | Complex Installation: You cannot simply "download and run
Solution: Run the fix-permissions command (unl_wrapper -a fixpermissions). Always.
After uploading, you must run the fix-permissions script, or the image will fail to start with a “Permission denied” error.
If you want, I can generate step-by-step commands and the exact folder structure for a specific OS (e.g., Cisco IOSv, Juniper vSRX, or pfSense). Which device/image should I detail?
chown -R root:root /opt/unetlab/addons/qemu-<name>/
chmod -R 755 /opt/unetlab/addons/qemu-<name>/
/opt/unetlab/wrappers/unl_wrapper -a fixpermissions
