If you are uploading this to a lab server like EVE-NG, you must ensure the file has execution permissions and the correct naming convention. : Usually /opt/unetlab/addons/iol/bin/ Common Issues
On modern 64-bit Linux systems (like those used by EVE-NG), you may need to install 32-bit libraries (libssl, libcrypto) to make this image run, as many IOU binaries are 32-bit. ⚠️ Important Note
: In raw IOU environments, a NETMAP file is used to define the logical connections between node IDs and their interfaces. Common Issues
