Here you go. https://www.gns3.com/
This is everything you'll need. You can create full networks, use any switch or router you want, and it actually works. Pretty neat stuff. It's all emulated but you can actually connect to the things and it's as if all the devices are real lol
Another option would be GNS3. You need to have the install ISOs for IOS for Cisco, Juniper, etc., but those can be cough found cough. I used it a little bit, but haven't had a chance to play around with it too much more.
There are plenty of free and inexpensive resources on the internet to teach yourself what you want to learn. Eventually, you'll need to get some hands on experience with actual hardware. A community college is probably your best bet since you are just starting out.
Since you stated "infrastructure", I'm going to assume you want to learn about networking. GNS3 is a free Cisco emulator that should help solve your lack of hardware problem. You'll have to do some searching to find good study resources that will teach you what you aim to learn.
You will need to do some labbing to pass CCNP R&S. GNS3, EVE-NGand Cisco D-Cloud. Search for David Bombal on Youtube to setup all three of the aforementioned lab sources.
Sounds like "yes" to answer the title question; but you don't have to quit to go learn new things.
Nobody is stopping you from building a home lab and learning anything you damn well please. Just to start:
https://www.gns3.com http://www.routereflector.com/unetlab/ http://virl.cisco.com
Invest in an eBay server or two and run VMs to your hearts content. Fire up Cisco, Juniper, Arista, or whatever vendor tickles your fancy virtual devices and off you go.
Also, while you're learning, find meet ups, go to conferences (lots have "social" passes that are cheap but don't get you access to the sessions, but you don't need that, just go to network in meat-space), start a blog about the stuff you're learning, etc..
Once you get your confidence and skills up (and hopefully met some people who can help!), apply for the jobs you actually want and hopefully get the money you need to do you.
Good luck!
I couldn't help but lurk on some of your earlier /r/homelab posts. If you have physical servers in your home it's one thing, and there is value in seeing, touching, plugging in to switches. However, for learning enterprise networking, your going to want to virtualize. Why? Because with virtualization you can spawn network devices until your PC bleeds, and make the kind of larger topologies you will see in enterprise environments. You can deploy it all, save it, write a terrible automation script that breaks everything, and then revert back and have everything redeployed in a snap.

Cisco VIRL: Easier to setup, but costs money
GNS3: Harder to setup but free
Is there any particular reason you're setting up both a pfSense box & an OpenWRT router?
> I am setting up my home lab as I want to learn and understand networking
Based off this alone you will want a managed switch, there are dozens of protocols you won't be able to play with without a managed switch.
EDIT: And on a side-note, I'll just leave this here.
Ahh, so now that you've revealed the fact that this is all happening within a simulator, that does put a spin on things.
GNS3 has bandwidth limits regarding how fast it can go, so I wonder if that is affecting the accuracy of your testing.
You might start a discussion thread over here:
Or over here:
If you're interested in cisco routing then there is a great piece of software you can use to setup emulated networks https://www.gns3.com/.
Granted I have not used this in years so I'm not sure how it's changed over the years but it was all free at the time. You also have to supply your own ROMs to memory.
If you have any experience in linux and just want to learn about IP routing then linux is a super easy and fun way to learn to setup your own routers and firewalls. Granted this requires some basic linux knoweldge beforehand or you'll just be learning linux.
> Do I have to have a DHCP server to do that, or can I just set it up using the switches?
You can set one up on the switch if you really want (depending on the model/IOS version).
Packet Tracer has been mentioned here already. It's a good starting point. I also recommend GNS3, because it can interface directly with the internet, virtual machines, and even real hardware. You could have your real switches as components in your virtual lab.
You can absolutely test your scripts against a GNS3 virtual network. I've found this is a great way to test and develop.
There's two ways I've done it. The first is to run the scripts directly on my Windows workstation and have a cloud in the GNS3 topology providing IP connectivity between Windows and the GNS3 devices. Or, my second way, I build a Linux guest machine in VMWare and connect it to the GNS3 topology, again through a cloud. This way works great for practicing Linux stuff, like Ansible.
I always test my scripts in GNS3 before going to production.. if it has a bug or something I definitely want to know about it before running against my entire production network!
Edit: forgot, there's one more super useful way that I use sometimes.. there's a "Network Automation" template in the GNS3 Marketplace. Just download that, import into GNS3, and drag-and-drop into your topology... it's a fully functional light-weight Linux machine right inside GNS3 and it has Python and Ansible preinstalled and ready to go.
It sounds like experience is your big handicap right now. Work with temp agencies and recruiters to get some more time under your belt.
Also, make sure you're learning. The CCNA tells me you can pass two tests, but nothing about what you actually know. You need to know all that material backward and forward.
You should be setting up a lab on a spare computer using GNS3. You have no idea how many people I've done phone screens for who don't have any kind of lab at home. That tells me they've passed a test and then just quit trying to get better.
Make sure you're tailoring your resume to the job you're applying for. As a network engineering manager who's looking for LAN and WAN guys, I get a ton of resumes here in DFW for guys with lots of experience. In Telco. I know they're sending the same resume to me and 100 other people and not even looking at the job description. Because of that, I have no idea if they're a good candidate because those resumes go in the trash.
Widen your job search to make sure you're catching all the possibilities. NOC is a good entry point, but also look for jobs as a DC Technician doing rack and stack on servers and gear.
Also remember that we're edging up to the end of Q4. A lot of people have had their hiring budgets for the year frozen or they're expended and, even if they are hiring, some managers are unwilling to take someone on right now knowing that they'll have a 2-3 month gap in being onboarded because of all the vacation being taken right now. If I hire you right now, it's at least two weeks for HR to get you into the system, a week to get you a laptop issued and now you're walking in the office as everyone else is walking out for turkey day.
Hope that helps.
A colleague of mine developed a web based networking diagram/whiteboard tool, that has been extremely useful in online collaboration with our global team. He is looking for more feedback and since I am frequently browsing various subreddits I told him I would see if I could get the word out. Is it a shameless plug, probably.. Is the app something that would be insanely useful for quick diagrams and talking points...most def. Website is http://netdraw.it
Here is his post on the GNS3 forums and their feedback... https://www.gns3.com/discussions/tool-for-networking-professional
In networking, vlans, firewalls , QoS, those are what I work on as a jack of all trades and have worked on when I was just networking. *Nix servers run the world so it's hard to say their hot right now, they always have been the backbone of computing.
Check out gns3 to help with the networking side of things. https://www.gns3.com
For Linux there is a ubuntu simulator, you can set up the ubuntu in your GNS3 altogether with other network devices and try without break any production device, that's the cool thing.
Check all the stuff you can use in GNS3 (appliances). Some are paid, some are free.
The GNS appliance definition files you can download from the website tell you the filename you need and its checksum, and will set it up with appropriate options.

How you obtain it is left as an exercise to the reader. This blog post suggests you only need to make an account
https://ethancbanks.com/free-networking-arubaos-cx-lab-image-from-aruba-networks/
This is the case with a lot of vendors, Juniper and Arista also only require an account. It's a sensible option if you ask me, it's not like you can really use it for any actual work, but what better way to get people hooked on your products.
Hey dick head! You're not a dick head, I just said that so you read my comment, there are too many comments here so I figure calling you a dick head might get your attention.
If you don't want to feel dumb, do this: download this https://www.gns3.com/
Download this: https://www.vmware.com/au/products/workstation-pro.html
Step one, make them work. Install gns3, the vm and virtualise networks with it. Stwp two, replicate some smaller versions of your work setup, start with what you know and move your way out to stuff you don't know. Step three, look for images or vm files online for network devices you have at work, you can get Cisco products and mikrotik and I don't know how many others.
Step four, after a week of off and on playing with this you will lose that fear you are talking about.
And on my initial attention grabbing statement in this response I say this, my methods may not be pure but my intentions are ;D
Good luck with it all
Edit: the software has evaluation versions by the way, that's all you'll need though
Yep, GNS3 lets you build a topology drag and drop pretty much like packet tracer, and can run pretty much anything that has a virtual image. They have a bunch of prebuilt files for importing appliances here. Not all of the virtual images can be obtained easily however.
CBT Nuggets var populära bland mina klasskamrater utanför ordinarie material. Dock varken gratis eller på svenska. Men du kan väl testa gratisveckan oavsett.
Om du vill lära dig just nätverk så är GNS3 bra för virtuell laboration. Det enda du behöver få tag på utöver programmet i sig. Är operativsystemen till de routrar och switchar du vill leka med.
Working with switches in GNS3 will cost you the same as working with routers in GNS3: Nothing
It's been 3yrs since I sat NP Switch, but I think the only thing the IOU images wouldn't do was PVLANs. Someone who has used them more recently may have better info.
Get an app to track your miles. Buy an AC inverter for your car. Ensure they get you a laptop with an SSD - electromechanical hard drives corrupt easily in moving cars. Make sure you have a phone plan with high hotspot limits (preferably have the business foot that bill). Ensure Bluetooth connectivity for the phone and laptop. Buy Rockport shoes - they're the only ones that never made my feet swell while working 18-hour days. Practice routing on a simulator - GNS3 is free to use.
This are some resources that may be of help:
https://github.com/sindresorhus/awesome#networking
When you got your Network+ have a look at the ccna if you need more in depth knowledge.
I guess the software is linux based. If yes start learning some linux basic skills. Know your way around the cli and how to trouble shoot the basics. The lpic1 would be a good starting point there.
Let me know if you need more info.
GSN3 is an open source network simulator and can emulate your devices or run them in virtual machines. https://www.gns3.com/
Also i haven't tried this so i'm not 100% certain, but you can map it to physical devices too.
I've implemented large networks after modeling them with GNS3. It's great for playing around with networks without spending lots of $ on hardware.
Free hypervisor.
What's your major?
The best advice I can give you is to study your heart out in the aspect of networking and cybersecurity. If your school is shy using virtual labs environments then use www.testout.com for a single year. I can say the $900+ library suite is well worth the pricetag, having used the virtual labs before. Ethical hacking is a culmination of networking and its innerworkings. For example, what layer are SQL injections a threat? AHA. Trick question. :)
What about Man-in-the-Middle (MITM) attacks?
What about the concepts of War Dialing, Warchalking, Wardriving, etc? What are those things? Are you vulnerable?
What is the use of Cain and Abel software? Forget wireshark, that's the only thing noobs talk about. What about meterpreter? Ever use SQLMAP?
What is the concept behind column cracking?
What about IP spoofing?
What is Reconnaissance, Scanning, Gaining Access, Maintaining Access, and Clearing Tracks called? Do you know how to completely move through these things?
What are honeypots? How can you tell if a network has a honeypot? How can you tell if the honeypot is built on a virtual machine(s)?
If you cannot answer these questions with 100% confidence you are not ready to touch kali linux. Want to learn bash? Use ubuntu. Most kids that download Kali, don't even realize how vulnerable they are using some shitty VPN to stay anon, while there are experts that can use kali natively to exploit an entire enterprise and leave without a making a sound.
Till then, keep practicing using GS3 simulation software. It helps a TON. Or you can even use Cisco Packet Tracer and set up a mock environment. Use the CLI to see what you can and cannot do without any tools.
I strongly suggest as you are in your early years to not undermine the level of intellect and knowledge you will require to become adept at this subject.
As a precursor to security, I think it would be beneficial to build some experience in networks first. It shouldn't been too hard since you have experience in radio communications. Maybe you can work with one of the network administrators of the IS division, work on a networking certification such as the Network+, or maybe even play around with virtualized networks in GNS3. This will build a solid foundation in networks and would be a good segue into security.
From there you can work towards security certifications such as the Security+ or CISSP and possibly get a job with the DoD or government contractors. If you already have a security clearance that will put you ahead of the other candidates.
A lot of people don't have a living situation to accommodate rack servers. They're certainly fair game if you do, but it's not as simple as picking one or the other for a lot of folks. I think the OP was really just pointing out a good deal, not specifically shopping for a server.
Regarding the 410, I'd look at the R210ii as a lightweight and low cost server for hosting pfSense and other light production services. I'd say the upside of replacing a commodity router and giving yourself extensive networking options is a great thing to do.
If you're just starting getting into networking start by working with GNS3 and Packet Tracer before you invest in a lot of hardware. Both will run just fine in VMs, and they provide appliances. Get as far as you can with those (plenty of people have passed their CCNA with nothing but the software), then look at what you need for hardware.
I would recommend installing Ubuntu Server, then installing gns3-server on the VM. As long as that VM has access to the network your client software is on, you will be able to connect to it as a "remote GNS3 server". Plenty of instructions on GNS3. Just do not install gns3-gui, only gns3-server.
Once your client is configured to connect to the remote server, you can (through Edit->Preferences) add IOS images and other things to the Gns3 server running on the Ubuntu VM.
Checkout the documentation and basic tutorial stuff on their site. When in doubt, Youtube, there are a ridiculous number of videos for setting up GNS3.
If you're super poor (like I am) https://www.gns3.com/ is a great application for messing around with networking and trying things out.
Other than that, I would just try to setup a Virtual Machine with Virtual Box and run a Linux / Windows server and learn about those.
Most people start out on the CCNA (Cisco Certified Network Associate) certification. It's important to keep in mind that this is just Cisco's version of networking, but it's good basic introduction.Todd Lammle's book (https://www.amazon.com/CCNA-Routing-Switching-Study-Guide/dp/1118749618) is a good place to start. Jeremy Ciora has a good video based program called CBT Nuggets to start in CCNA (https://www.cbtnuggets.com/certification-playlist/cisco/56440).
While you are doing that, download GNS3. (https://www.gns3.com/software). This will let you get hands on and start configuring stuff and let you actually program virtual routers and switches and actual follow along with your lessons. You'll have to get router images to use. Some are free, some have to be "found".
After you've gone through the lessons and done a lot of hands on, go to your local Pearson Vue test center (there is generally one on every base) and take your CCNA exam. It's like $250-300. All in, you'll probably be around $400.
I run a single old tower with ESXi. My whole hole lab sits in a computer. Depending on the specs you may not need to invest in any hardware. Take a look at GNS3 for networking
https://www.gns3.com/marketplace/appliances you'll need the ubuntu appliance (there's only two, choose which best suits what you're trying to do). Import the appliance into GNS3 then load the image to the appliance.
I mean, you either make your own Cloud (OpenStack), or just add containers for whatever functionality you want to put up. https://www.gns3.com/ looks like a project that could help you with your networking skills as well.
There are also some libraries and whatnot that do load management that roll over to aws, but I think it requires programming experience as well.
I directed the question here instead: https://www.gns3.com/community/support/qemu-machine-emulators-and-tools-100-cpu-usage
Install the GNS3 VM on the server, make a guess of how much ram and cpu you will need(64GB, 8VCPU for ME). Install GNS3 GUI and teamviewer on your desktop.
Add the server as "Main server" in the GNS3 settings and turn on "easy access" to teamviewer om your computer.
It's by far the easiest way to get going and is currently how i run my networking lab setup.
Unless you’re in IT and are seeking career advancement, I don’t think it’s worth it. You won’t get the hands on experience you need from a cert. Your time and money would be much better spent on some networking courses at your local community college. Alternatively, you can use a tool like GNS3 to play around with things before you implement them in real life.
That is GNS3 ... Graphical Network Simulator.
If you are serious about Cisco, it's worth having.
The virtual interfaces in the example are ATM and OC3. I'm also building a sample BGP network in this example.
What /u/geruta said in https://www.reddit.com/r/vmware/comments/gowahm/error_on_esxi_65_180_when_attempting_to_use_a/frijv39/ .
An upgrade might also be useful - what version of esxi is running on the server, and what hardware is it running on?
You reference a patch - is https://www.gns3.com/discussions/error-loading-gns3-vm-ova-into-e what you found?
Apple iOS? Nintendo IOS? Cisco IOS?
Actually it doesn't matter because the answer is "no" for all three. VirtualBox only virtualizes x86-based machines, and none of those run on x86 hardware.
For Apple devices, you can use Simulator, included with Xcode on mac OS.
For Nintendo Wii devices, you can use Dolphin.
For Cisco devices, you can use GNS3.
I've not got as far as running the tshoot lab! I have built quite a large OSPF topology though with various area types and not faced any issues. Maybe try a small set up using QEMU or dynamips images to check it's not config?
A bit of a long shot but, I came across this as well. Are you using NAT?
GNS3 is a Network virtualization environment. (www.gns3.com). In order for GNs3 to have full capability, KVM is required. KVM requires a 64 bit OS for RPi. The current buster for RPi 4 is only 32bit.
Learn as much as you can, learn how to troubleshoot especially, get used to analyzing, get used to logic.
First Learn Active Directory, I like the virtual labs on Microsoft's website. It is the basis for alot of the rest of IT particularly in the windows side.
Second, Learn Powershell. It is becoming a more and more important language for windows systems and will be the basis for alot of other technologies.
After: Learn technologies like office 365, aws and azure first. It'll be easier for you to get started with cloud technologies than it will be to build out your own hardware lab.
If you decide you want to specialize in Networking, use GNS to build out a virtual lab and get familiar with networking and cisco.
Jobwise: See if you can get an internship when you get out of highschool, you'll likely be stuck doing some basic helpdesk/password resets at first. But if you show you actually are good and can handle the work, you may be able to get out of password reset hell soon.
I use GNS3 Applicance:

I had a lot of problems getting the GNS3 VM to run in the past. But recently got it to work in a Ubuntu server VM. Set one up, give it internet access and run these commands. Thanks to this post.
cd /tmp curl https://raw.githubusercontent.com/GNS3/gns3-server/master/scripts/remote-install.sh > gns3-remote-install.sh bash gns3-remote-install.sh --with-iou --with-i386-repository
Basically this runs this script to install what you need automatically.
https://github.com/GNS3/gns3-server/blob/master/scripts/remote-install.sh
When done don't forget to change the 'gns3' user password using sudo. I restarted and got locked out of the VM because I didn't have the password and I couldn't find the default password online.
Fair enough. The gear Jeremy recommended has been fine for my CCNA, but I have been using GNS3 a lot recently. I definitely agree though, if OP is looking to really get into this, it wouldn’t hurt to invest a little more money on better gear.
To be blunt, you can't really afford to be an OS "snob" anymore. Learn Windows. Learn macOS. Learn Cisco IOS. On the network front, check out https://www.gns3.com/ to more deeply learn about routing.
Knowing how to attack Linux systems is great, but there are all kinds of other targets out there that you are missing.
Start applying for Tier 1 NOC positions in ISP's, there are plenty of jobs going. Look for a company that is either starting or doing a rollout of some form as they are always looking for bodies. Ideally you could apply for a second level job in places like BT, Vodafone etc and get some experience working with other company networks before working your way up to NOC. I have been doing this 13 years now, starting at 23 I joined a tech support call center as a 1st level tech engineer in an ISP, over the years i have been second level, NOC, senior NOC engineer, NOC manager and IP engineer. Now i look after infrastructure and core networks but with the experience i have built up I'm looking to start contract work (that's where the big money is).
As others have said industry certificates are a lot more important than degrees however having a degree also adds weight to your knowledge base. It a fun yet challenging field to get into and you will be surprised what you end up being involved in like radio networks, fibre, working alongside companies like ESB and eNet on projects, 4G and 5G networks. Some of the characters you will meet as well are great, a few cunts but most are awesome.
IF your looking to get yourself a home lab to help with study then i would recommend checking out GNS3. You can build yourself networks to test things out from multiple vendors.
Anyway good look dude your getting into a great industry.
https://www.gns3.com/marketplace/labs Might not be exactly what you want (I can't open this on my current PC to see what the files open up to, but I'm guessing its some form of topology with instructions on what to build). Unless there is a repository somewhere or someone is nice enough to send you save files, maybe spending a little time building any of these labs that seem useful for what it is that you want to do is the least time sink option.
>Also when it comes to networking you cant really virtualize network equipment
well this is very untrue
If you are just going to do networking, no need for anything fancy. Don't let (what seems) to be the majority influence what you should do/get. You can use GNS3. It's a network simulator where you can run a virtual network of routers, switches, ASAs, and other network devices.
There is a template in the GNS3 Marketplace and you can import the template and download the required setup files. Okay this is not a switch but does run Comware Version 7 and allows you to get a feel for commands and navigation. Found this easy to setup after doing a one day HP course.
Link: https://www.gns3.com/marketplace/appliance/hp-vsr1001
BTW - HP do have something that can be installed and setup as a stand alone emulator from what I hear but I doubt this would work with GNS3
From your post, it sounds like you're doing a lot of reading and not much lab work. If you do that, it won't help you in work and you'll never remember it. When I was learning networking, https://www.gns3.com/ was the way to go to actually set up virtual networks. /r/networking might have something better these days.
When you say helpdesk technician, are you talking about desktop support? If so, some of the advanced stuff in CCNA won't really help you immediately. You might take the CCENT and move to a different technology. There's a lot of business-speak about being 'T-shaped' -- having a base of skills across IT and then a deep specialty -- but it really is a good idea.
It's helpful to be able to apply the results of your studies during work. Like if someone can't reach an application server, can you determine whether or not it's a networking issue?
You mentioned becoming a sysadmin (might be broad, sysadmin at a small company could do everything, while a sysadmin at a large company could just focus on virtual machines). After CCENT I would start with the windows 7/10 certification. It will help you immediately at your work, and give you a base from which to dig into windows servers/admin. After that jump to scripting. Those three are really a sort of trifecta (operating system, network, scripting). Scripting might help you automate routine tasks at work, giving you more time to focus on the interesting stuff and learn. The language doesn't matter, pick whatever you can implement and use in your work environment.
Final note -- Keep looking around at work for what you don't know, and what you could learn that would help you day to day.
https://www.gns3.com/qa/no-console-output-qemu
"I had a console connection issue with ASAv 9.6.1 and 9.7.1. Console was dead and i spent hours looking for any information related to my problem. I was able to open console to QEMU IOU L3/2 and cisco 3725 router image without any troubles. GNS is running on Windows 10 i7 system with VMware Workstation 12. GNS3 VM started just fine, picking up address from my DHCP server and GNS3 was able to connect to it and upload all my ASAv images. I was also able to start ASA, at list topology summary indicator was green, which meant what machine is up and running, but no console connection.** Turn out it was my free AVG Antivirus**. Somehow it was blocking connection to ASA. Even after i whitelisted dynamips.exe as "GNS Doctor" suggested and turned it OFF, AVG was still doing something weird to block ports that ASAs uses to listen for VNC connection requests or vice versa. I had to uninstall it completely. Once AVG uninstalled, everything started to work."
I used to be a network guy and everyone used this emulator to learn. It's the best learning tool available. It basically mimics real world network devices and allows you to build virtual networks just like if they were real and test them. Plenty of YouTube videos to take you through how to set it up, get started and build networks step-by-step. If you really want to learn, this and YouTube is all you need. Good luck.
And if you can't afford the equipment (which is totally understandable, it's not like helpdesk jobs typically pay six figure salaries, my first helpdesk job paid a measly $33280 annually), then go with GNS3. You will have access to network equipment but abstracted into a virtual context. Word to the wise, if you go with GNS3, always have scratch paper out and a pen so you can draw out the architectures, it's better to visualize what you're learning if you can't get access to the actual equipment.
This link helped me fix my configs when testing NAT64. I suspect if you put in a "nat64 v4v6 ... " for the return traffic then it'll work. That's what worked for me anyway.
https://www.gns3.com/discussions/nat64-configuration-for-connecti
If that's the case, you might want to do more looking into CCNA and other Cisco learnings. GNS3 is a network hardware virtualization program...I can't tell you where to get iOS images from, but they exist on the interwebz. While linux is commonly used in server/corporate environments, knowledge of bash commands and linux functions won't translate that much to networking. Juniper, Dell, HP, almost all of the other companies that make networking gear pull some measure of inspiration from Cisco...so I'd start there. Good luck!
You can also go for GNS3 if you'd like to have a platform that can expand out to non-Cisco equipment to test out. All you need for GNS3 is to download the appropriate images of the router/switch/etc. model that you're looking for.
GNS3 is the best IMO.
Can run pretty much any virtual router available, as well as integrated VMs and docker containers.
The real issue is finding virtual appliances that closely match the devices you have in production, so it comes down to what is available from your vendor.
Here is the GNS3 support list:
On the network side... She may wish to check out https://www.gns3.com/. She can emulate hardware, set up virtual networks, and so on. This is better than cluttering up with hardware. If necessary she should also pirate the images. If headed towards networking, voice/sip/telco should be investigated as those things are being married with networking these days. And downloading SD WAN for dummies and getting primed up on SD wan shit might be in order.
Might I offer a slightly different solution to your project.
If you are looking to create 4 different virtual networks in VMware with 4 different firewalls I would look into something like GNS3. You can run VMs from it that can run a bunch of different OSs including pfSense.
I would say I am decent. The thing is with ASA's they need to be hosted in a virtual machine. Creating this VM and hosting it inside of GNS3 sucks...
However with the newer GNS3 you just get the template for the ASAv and it will create the virtual machine as a docker container inside of the GNS3 virtual machine. But you will need access to a virtual ASA vmdk or ova file.
Templates can be found here: https://www.gns3.com/marketplace/appliances
Make use of the templates because they will tell you which software pieces you need to deploy a certain device. After you get enough of em, you can lab out pretty good. I use the juniper vSRX almost exclusively. You can register on junipers website and grab a trial one as well.
GNS3 gets my vote! It can be confusing at first, but you can find a bunch of tutorials online. It's a super powerful program that you can use to simulate network environments.
You can emulate routing and switching on the network level, but pushing actual traffic through it blows ass. Also, it becomes difficult to SPAN the traffic for inspection. For your case, go pick up some used CISCO hardware, they have CCNA kits for like 200 bucks for a switch, router, and WAP's.
Some stuff you can also do in the GNS3 using 3725 with NM-16ESW card. You can disable the L3 stuff globally or also just on specific port. Some links https://www.gns3.com/support/docs/switching-simulation-in-gns3-ver

Why wouldnt you? You have a paid smartnet account and you arent passing IOS images around to people. You are using in house for yourself to test/build out configs.
Search harder.
From the source, it means that the path to iouyap is not set, which you didn't need, since the error message says exactly that.
From the documentation, there is an aptly-named configuration variable under IOU:
> [IOU]
> ; iouyap executable path
> iouyap_path = /usr/local/bin/iouyap
