To download and set up images for , it is important to understand that the software itself does not come with pre-installed vendor images due to licensing restrictions [11]. You must obtain these images legally from vendors like and then upload them to your EVE-NG server 1. Legal Ways to Obtain Images
The most reliable and legal method for acquiring network device images for labbing is through official vendor channels: Cisco Modeling Labs (CML) : Purchasing a CML Personal subscription
provides legal access to a wide range of official Cisco virtual images (IOSv, IOS-XE, NX-OS) that are compatible with EVE-NG [16, 18]. Vendor Support Contracts
: If your organization has an active support contract with vendors like
, you can download virtual appliance images directly from their respective support portals [11, 18]. Free Trials
: Some vendors offer free trial versions of their virtual appliances (e.g., Arista vEOS Go to product viewer dialog for this item. ) which can be used for learning purposes [14]. 2. Image Installation Workflow
Once you have the image files, follow these general steps to add them to EVE-NG: Prepare the Image : Ensure the image is in a supported format, such as for QEMU or for Cisco IOL/Dynamips [11, 13]. Upload to EVE-NG : Use an SCP client like
to transfer the files to the correct directory on your EVE-NG server [19, 22]: QEMU images /opt/unetlab/addons/qemu/ IOL images /opt/unetlab/addons/iol/bin/ Dynamips images /opt/unetlab/addons/dynamips/ Fix Permissions : After uploading, you
run the following command via the EVE-NG CLI to ensure the system can access the new files [11]: /opt/unetlab/wrappers/unl_wrapper -a fixpermissions Use code with caution. Copied to clipboard 3. Managing Different Vendors
Different vendors require specific naming conventions for their folders and files to be recognized by EVE-NG. Detailed step-by-step guides for each supported vendor are available in the EVE-NG Documentation How-To section Directory Type Common File Format QEMU / IOL / Dynamips For more comprehensive setup details, you can refer to the EVE-NG Community Cookbook for EVE-NG?
Downloading and setting up EVE-NG images is the most critical hurdle for anyone building a virtual network lab. While EVE-NG provides the platform, it does not provide the vendor images (like Cisco, Juniper, or Palo Alto) directly due to licensing and copyright.
Here is the "full story" of how you get from a fresh installation to a fully functional lab with all the images you need. 1. The Legal Starting Point
Because EVE-NG Limited cannot legally distribute copyrighted software from vendors, you have two main legitimate paths to acquire images:
Official Vendor Portals: If you have a support contract with a vendor (e.g., Cisco, Fortinet), you can download the KVM/QCOW2 versions of their software directly from their websites.
Cisco Modeling Labs (CML): Many engineers purchase a Cisco CML license specifically to legally obtain the latest IOSv, IOSvL2, and ASAv images, which are then manually exported to EVE-NG. 2. The "Full Pack" Shortcut
To avoid the tedious process of manual conversion, many users look for "Full Packs" or "EVE-NG Spoto" collections.
What they are: These are pre-built virtual disks (VMDKs) that come with 30+ popular network images (ASA, CSR1000v, Fortigate, etc.) already configured.
The Advantage: It saves weeks of manual configuration. You simply import the VMDK into your VMware/ESXi environment and the images are ready to boot.
Alternative: Platforms like PNETLab offer a built-in store where you can download images directly through the GUI, simplifying the process compared to EVE-NG's manual CLI method. 3. Manual Installation Workflow
If you download an individual image (like a Palo Alto firewall or a Windows VM), you must follow a strict three-step process:
Creation: Create a specifically named directory on the EVE-NG server (e.g., /opt/unetlab/addons/qemu/paloalto-11.2.0/).
Upload: Use an SFTP client (like WinSCP or FileZilla) to move the image file into that directory.
Permissions Fix: This is the "secret sauce." You must run the following command in the EVE-NG CLI to make the image usable:/opt/unetlab/wrappers/unl_wrapper -a fixpermissions. 4. Verification and Lab Use
Once uploaded and fixed, you can add "Nodes" in the EVE-NG web interface. If the node name is blue, the image is installed correctly; if it is grey, the files are missing or in the wrong directory.
If you want to dive deeper into a specific vendor,g., CheckPoint vs. Huawei).

Below is a complete guide on how to find, upload, and verify images for your lab. 1. Finding Legitimate Image Sources
Downloading images from unofficial sites can lead to security risks or corrupted files. Use these official and community-vetted paths:
Official Vendor Portals: The most secure way to get Cisco IOS, XE, or NX-OS images is through Cisco Software Central with a valid license.
Free Virtual Images: Several vendors offer free virtual appliances that work natively with EVE-NG: Arista vEOS: Available for free with a user account. Extreme EXOS/VOSS: Often available for free evaluation. VyOS / BSDRP: Open-source network OS images.
EVE-NG Full Pack (Paid): Some third-party services like Dynamips offer curated "Full Packs" with pre-configured images for a fee, though these are not official EVE-NG products. 2. Supported Image Formats
EVE-NG supports three primary image types. Each must be placed in a specific directory on your EVE server:
QEMU (qcow2): Most common for modern firewalls and routers (/opt/unetlab/addons/qemu/).
Dynamips (bin): Older Cisco IOS routers (/opt/unetlab/addons/dynamips/).
IOU/IOL (bin): Cisco "IOS on Unix" lightweight images (/opt/unetlab/addons/iol/bin/). Linux images - - EVE-NG
Comprehensive Guide to Managing EVE-NG Images Acquiring and installing images for
is a multi-step process that varies depending on the vendor and image type. EVE-NG itself does not provide copyrighted vendor images
(like Cisco or Juniper) due to licensing restrictions. Users must obtain these images through official vendor channels or legal subscriptions. 1. Methods for Acquiring Images
There are several ways to gather the necessary files for your lab: Official Vendor Portals
: The most secure method is downloading images directly from vendors like , Juniper, or Arista. For Cisco specifically, purchasing a Cisco Modeling Labs (CML)
subscription is the recommended legal path to get a wide array of working images (IOSv, IOSvL2, ASAv, etc.). Third-Party Packs
: Some community members share "Full Packs" or torrents containing categorized vendor images (Cisco, Palo Alto, etc.).
Note: Use these at your own risk, as they may violate copyrights or contain unverified files. Direct Download Scripts
: Advanced users sometimes use tools or scripts (like those found in similar emulators like PnetLab) to "pull" images directly into the environment via SSH. Cloud Images
: Free open-source images for Linux (Ubuntu, Debian) can be downloaded directly to your EVE-NG server using from their respective official cloud image repositories. 2. Image Types and Directories
EVE-NG supports three main types of images, each with a specific storage path on the server: Cisco Dynamips images (Cisco IOS) - - EVE-NG
Master Guide: How to Download and Setup EVE-NG Images If you are pursuing a career in network engineering, EVE-NG (Emulated Virtual Environment Next Generation) is likely your best friend. It is a powerful multi-vendor network emulation software that allows you to build complex topologies. However, a common hurdle for many beginners is figuring out how to download all EVE-NG images and get them running properly.
This guide will walk you through the types of images you need, where to find them, and the correct way to install them. 1. Understanding the Types of EVE-NG Images
Before you start downloading, you need to know that EVE-NG supports three main categories of images: Dynamips: Legacy Cisco IOS images (older, less used today).
IOL (IOS on Linux): Lightweight Cisco images that run as Linux processes. Great for large topologies because they use very little RAM.
QEMU/KVM: This is the "gold standard." It includes modern images like Cisco vIOS, Arista EOS, Juniper vMX/vQFX, Palo Alto, Fortigate, and even Windows/Linux workstations. 2. Where to Download EVE-NG Images
It is important to note that network OS images (like Cisco, Juniper, or Palo Alto) are proprietary software. Legally, you should obtain them via official vendor support contracts. Official Sources:
Cisco Modeling Labs (CML): The most reliable way to get legal Cisco images (vIOS-L2, vIOS-L3, ASAv) is by purchasing a CML subscription and exporting the images to EVE-NG. To download and set up images for ,
Vendor Websites: Many vendors like Arista, Juniper, and Fortinet offer free trial versions of their virtual appliances (vEOS, vSRX) on their official download portals. Community Sources:
Many engineers search for "EVE-NG image packs" or "Mega.nz links" provided by the community. While these are widely available on forums and Telegram groups, always exercise caution and scan files for integrity. 3. How to Install Images in EVE-NG
Downloading the file is only half the battle. You must place it in the correct directory and fix permissions for it to show up in your lab. Step 1: Upload the Image
Use a tool like WinSCP or FileZilla to connect to your EVE-NG IP address. Path for QEMU: /opt/unetlab/addons/qemu/ Path for IOL: /opt/unetlab/addons/iol/bin/ Step 2: Correct Folder Naming EVE-NG is very strict about folder names. For example: A Cisco ASAv image must be in a folder starting with asav-.
A Palo Alto image must be in a folder starting with paloalto-. Step 3: Fix Permissions
This is the most critical step. After uploading any new image, log into your EVE-NG CLI via SSH (PuTTY) and run the following command: /opt/unetlab/wrappers/unl_wrapper -a fixpermissions Use code with caution.
Without this command, your nodes will likely gray out or fail to start. 4. Essential Images for Your Lab
If you are building a balanced lab, aim to download these "must-haves": Cisco vIOS L2 & L3: Essential for CCNA/CCNP studies. PFsense: Great for learning firewalling and NAT.
Ubuntu/Windows Server: To test end-to-end connectivity and services like DNS/DHCP.
Arista vEOS: Excellent for learning Data Center switching and automation. Conclusion
Setting up your EVE-NG library takes time, but having a full suite of images allows you to simulate almost any real-world environment. Focus on getting QEMU images for the best performance and modern features.
Comprehensive Guide: How to Download and Setup All EVE-NG Images
If you are a network engineer, student, or enthusiast, EVE-NG (Emulated Virtual Environment Next Generation) is likely your go-to platform for labbing. However, the software itself is just the engine; to make it run, you need the "fuel"—the qcow2 or bin images for Cisco, Juniper, Arista, and Mikrotik.
Finding a central place to download all EVE-NG images can be a challenge due to licensing and legal restrictions. This guide will walk you through the types of images you need and the proper way to source them. 1. Understanding EVE-NG Image Types
Before you start hunting for download links, you need to know what you’re looking for. EVE-NG generally uses three types of images: Dynamips: Older Cisco IOS images (e.g., 7200, 3725).
IOL (IOS on Linux): Lightweight Cisco images that run natively on Linux (very CPU/RAM efficient).
QEMU/KVM: Modern images for high-end appliances like Cisco Firepower, Palo Alto, Fortigate, and F5 Load Balancers. 2. Where to Download EVE-NG Images
While many third-party sites offer "Mega" or "Google Drive" packs containing "all images," the safest and most professional way to acquire them is through official channels. Official Vendor Sites (Recommended)
Most vendors provide "Trial" or "Free" versions of their virtual appliances:
Cisco Modeling Labs (CML): The best legal way to get updated Cisco IOSv, IOS-XRv, and ASAv images.
Arista: Offers the vEOS image for free on their support portal. Juniper: Provides vSRX and vMX evaluation copies.
Mikrotik: The Cloud Hosted Router (CHR) image is free to download and perfect for EVE-NG. Community & Forum Resources
If you are looking for specific older binaries, the EVE-NG Community and various network engineering forums often share naming conventions and md5 hashes to help you verify that the files you find online are authentic and untampered. 3. How to Upload Images to EVE-NG
Once you have downloaded your images, you cannot just drop them into a folder. EVE-NG requires a specific directory structure. Step-by-Step Installation:
Use WinSCP or FileZilla: Connect to your EVE-NG IP address using SSH (Port 22). Navigate to the Directory: For QEMU: /opt/unetlab/addons/qemu/ For IOL: /opt/unetlab/addons/iol/bin/
Create a Folder: Every QEMU image must be in its own folder starting with the vendor prefix (e.g., asav-9.14.1).
Rename the File: Most QEMU images must be renamed to virtioa.qcow2 to be recognized. Install the required tools: John needed to install
Fix Permissions: This is the most critical step. Open the EVE-NG CLI and run: /opt/unetlab/wrappers/unl_wrapper -a fixpermissions Use code with caution. 4. Popular Images to Include in Your Lab
If you are building a "Master Lab," ensure you have downloaded these essentials: Cisco vIOS L2/L3: Essential for CCNA/CCNP.
Palo Alto VM-Series: The industry standard for next-gen firewalls. pfSense: Great for open-source routing and firewalling.
Windows/Linux Desktop: To test end-to-end connectivity within your topology. 5. Important Legal Disclaimer
Always remember that Cisco IOL and many other images are proprietary. While "all-in-one" download packs are available on the web, using them in a corporate environment without proper licensing can lead to compliance issues. For personal study, always prioritize images obtained through a Cisco Learning Network subscription or vendor trial programs.
To download all EVE-NG images effectively, focus on building your library incrementally. Start with the core routing and switching images from CML, and expand into security and load balancing as your labbing needs grow.

done
Please note that you'll need to modify the script to include your EVE-NG API token, username, and password. Additionally, be aware of any usage limits and terms of service when using the EVE-NG API.
To set up a complete lab environment, you cannot download a single "all-in-one" file containing every image due to licensing and legal restrictions
. Instead, you must source individual images from vendors or community repositories and upload them to specific directories within your EVE-NG VM. Where to Find Images
Most professional network images require a valid service contract with the respective vendor. However, many offer free trial or "community" versions: Cisco Systems: Official images like are available via Cisco Modeling Labs (CML) You can download the image for free by creating a guest account on the Arista Software Downloads trial images can be found on the Juniper Trials Open Source/Linux: Ready-to-go images can be downloaded from the EVE-NG Documentation or built manually. Directory Structure for Uploads
Once downloaded, you must move the files to EVE-NG using an SCP client (like WinSCP or FileZilla). The destination depends on the image type: Image Type Destination Directory on EVE-NG (Cisco ASAv, Palo Alto, Windows) /opt/unetlab/addons/qemu/ (Cisco L2/L3 Switches) /opt/unetlab/addons/iol/bin/ (Old Cisco IOS) /opt/unetlab/addons/dynamips/ Critical Post-Upload Step After uploading any new image, you
fix the file permissions, or the nodes will fail to start. Run this command in the EVE-NG CLI: /opt/unetlab/wrappers/unl_wrapper -a fixpermissions Use code with caution. Copied to clipboard Naming Conventions:
EVE-NG is strict about folder names. For example, a Palo Alto folder must start with paloalto-11.2.0 Resources: EVE-NG Supported Images List
Since "Download All EVE-NG Images" is not a single software product but rather a widely searched term for a collection of pre-packaged virtual machine images (qcow2 files) used within the EVE-NG network emulation platform, this review focuses on the process, the packages, the risks, and the user experience.
cd /opt/unetlab/addons/qemu/ mkdir -p <node-name> # e.g., mkdir -p cisco-asav-941
/opt/unetlab/wrappers/unl_wrapper -a fixpermissions
Do not attempt to script downloads from Cisco or Juniper without authentication—you will be blocked and possibly reported.
