How to Install and Set Up Ubuntu 24.04 on VMware Workstation Pro 17 in Windows 11

Overview:

Setting up Ubuntu on VMware is a crucial skill for DevOps professionals who want to create isolated environments for testing, development, and automation workflows. VMware allows you to run multiple virtual machines (VMs) on a single system, enabling you to experiment with different Linux distributions without altering your primary operating system. In this hands-on guide, we’ll walk through the steps to install and configure Ubuntu on VMware, covering the key settings and best practices for optimizing performance in DevOps environments.

VMware: Getting Started

Step 1: Install VMware Workstation

To begin, you’ll need VMware Workstation or VMware Player installed on your system. Here’s how:

- Download VMware: Visit the official VMware website and download either VMware Workstation or VMware Player depending on your preference. Workstation is a paid tool with advanced features, while Player is a free option that’s perfect for basic VMs. - Install VMware: Run the installer and follow the setup wizard. Once installed, launch VMware.

Step-by-Step: Installing Ubuntu on VMware

Step 1: Download Ubuntu ISO

- Go to the [official Ubuntu website](https://ubuntu.com/download) and download the LTS (Long Term Support) version of Ubuntu, ensuring you have a stable version for long-term usage in your DevOps workflows.

Step 2: Create a New Virtual Machine in VMware

- Open VMware Workstation or VMware Player and select “Create a New Virtual Machine.” - Choose the ISO image by selecting the downloaded Ubuntu file, then click Next.

Step 3: Allocate Resources

- CPU: Assign at least 2 CPUs for smooth operation. - RAM: Allocate at least 4GB of RAM for optimal performance. You can assign more if your system allows. - Storage: Provide at least 20GB of disk space, especially if you plan to install DevOps tools.

Step 4: Installation of Ubuntu

- Start the VM, and Ubuntu’s installation wizard will appear. - Follow the prompts: choose language, keyboard settings, and select Install Ubuntu. - Choose installation type (erase disk if it’s a fresh VM) and configure time zones, user account, and password. - After installation, update your system by running:  ```bash  sudo apt update && sudo apt upgrade -y  ```

Step 5: VMware Tools Installation

Installing VMware Tools improves VM performance, enabling better integration with the host machine.

- In VMware, go to the VM menu and select Install VMware Tools.  ```bash  sudo apt install open-vm-tools open-vm-tools-desktop -y  sudo reboot  vmware-toolbox-cmd -v  ``` Verify VMware Tools Installation:

 ```bash  vmware-toolbox-cmd -v  ```

Step 6: Post-Installation Setup for DevOps

- Install Basic DevOps Tools:  ```bash  sudo apt install git curl vim  ``` - Enable SSH Access:  ```bash  sudo apt install openssh-server  sudo systemctl enable ssh  sudo systemctl start ssh

Best Practices for Installing and Setting Up Ubuntu on VMware

1. Resource Allocation: Ensure you allocate sufficient CPU, RAM, and storage based on the workloads. For most DevOps tasks, assign at least 2 CPUs and 4GB of RAM for optimal performance. More demanding workloads may require additional resources.

2. Snapshots: Regularly take VM snapshots before major changes or installations. This allows you to revert to a stable state if something goes wrong during configuration or software testing.

3. VMware Tools Installation: Always install VMware Tools after setting up the OS. This ensures seamless mouse integration, smoother graphics, and better performance, reducing potential bugs and lag in your virtual environment.

4. Partitioning: For better performance and management, use custom partitioning if needed. This helps in allocating different parts of your virtual disk to `/`, `/home`, and `/var` partitions, improving system performance and flexibility in future updates or installations.

5. Automated Backups: Set up automated backups or export your VMs periodically. This practice is particularly important if your VMs store critical configurations, applications, or databases.

6. Networking Configuration: Ensure that your virtual machines are correctly configured to access the internet and your local network. Consider using NAT or Bridged Network options, depending on your networking needs. NAT works well for internet access, while Bridged is ideal for networked environments.

7. Security Considerations: Configure firewalls and SSH access carefully to secure your VMs from unauthorized access. Set up strong user permissions, enforce password complexity, and enable SSH keys for secure remote access.

8. Regular System Updates: Frequently update Ubuntu systems to ensure they are protected from vulnerabilities. Use the following commands to update packages:    - For Ubuntu:      ```bash      sudo apt update && sudo apt upgrade      ```

9. Monitor Resource Usage: VMware allows you to monitor CPU, memory, and storage usage. Use these tools to ensure that your VMs are not consuming excessive resources, especially in shared environments.

10. Test Environments: Use VMs as sandbox environments to test and experiment with new DevOps tools like Docker, Kubernetes, Jenkins, or Ansible before deploying them in production.

Conclusion:

By installing and setting up Ubuntu on VMware, you gain the flexibility to experiment with DevOps tools, test automation workflows, and learn Linux system administration in a safe and isolated environment. This hands-on tutorial provides you with the foundation to run and manage your Linux VMs effectively, setting you up for success in DevOps tasks ranging from development to deployment automation. Follow along in this video as we guide you step-by-step to mastering Linux installations on VMware for your DevOps journey.

Tools of the Trade for Learning Cybersecurity

I created this post for the Studyblr Masterpost Jam, check out the tag for more cool masterposts from folks in the studyblr community!

Cybersecurity professionals use a lot of different tools to get the job done. There are plenty of fancy and expensive tools that enterprise security teams use, but luckily there are also lots of brilliant people writing free and open-source software. In this post, I'm going to list some popular free tools that you can download right now to practice and learn with.

In my opinion, one of the most important tools you can learn how to use is a virtual machine. If you're not already familiar with Linux, this is a great way to learn. VMs are helpful for separating all your security tools from your everyday OS, isolating potentially malicious files, and just generally experimenting. You'll need to use something like VirtualBox or VMWare Workstation (Workstation Pro is now free for personal use, but they make you jump through hoops to download it).

Below is a list of some popular cybersecurity-focused Linux distributions that come with lots of tools pre-installed:

Kali is a popular distro that comes loaded with tools for penetration testing

REMnux is a distro built for malware analysis

honorable mention for FLARE-VM, which is not a VM on its own, but a set of scripts for setting up a malware analysis workstation & installing tools on a Windows VM.

SANS maintains several different distros that are used in their courses. You'll need to create an account to download them, but they're all free:

Slingshot is built for penetration testing

SIFT Workstation is a distro that comes with lots of tools for digital forensics

These distros can be kind of overwhelming if you don't know how to use most of the pre-installed software yet, so just starting with a regular Linux distribution and installing tools as you want to learn them is another good choice for learning.

Free Software

Wireshark: sniff packets and explore network protocols

Ghidra and the free version of IDA Pro are the top picks for reverse engineering

for digital forensics, check out Eric Zimmerman's tools - there are many different ones for exploring & analyzing different forensic artifacts

pwntools is a super useful Python library for solving binary exploitation CTF challenges

CyberChef is a tool that makes it easy to manipulate data - encryption & decryption, encoding & decoding, formatting, conversions… CyberChef gives you a lot to work with (and there's a web version - no installation required!).

Burp Suite is a handy tool for web security testing that has a free community edition

Metasploit is a popular penetration testing framework, check out Metasploitable if you want a target to practice with

SANS also has a list of free tools that's worth checking out.

Programming Languages

Knowing how to write code isn't a hard requirement for learning cybersecurity, but it's incredibly useful. Any programming language will do, especially since learning one will make it easy to pick up others, but these are some common ones that security folks use:

Python is quick to write, easy to learn, and since it's so popular, there are lots of helpful libraries out there.

PowerShell is useful for automating things in the Windows world. It's built on .NET, so you can practically dip into writing C# if you need a bit more power.

Go is a relatively new language, but it's popular and there are some security tools written in it.

Rust is another new-ish language that's designed for memory safety and it has a wonderful community. There's a bit of a steep learning curve, but learning Rust makes you understand how memory bugs work and I think that's neat.

If you want to get into reverse engineering or malware analysis, you'll want to have a good grasp of C and C++.

Other Tools for Cybersecurity

There are lots of things you'll need that aren't specific to cybersecurity, like:

a good system for taking notes, whether that's pen & paper or software-based. I recommend using something that lets you work in plain text or close to it.

general command line familiarity + basic knowledge of CLI text editors (nano is great, but what if you have to work with a system that only has vi?)

familiarity with git and docker will be helpful

There are countless scripts and programs out there, but the most important thing is understanding what your tools do and how they work. There is no magic "hack this system" or "solve this forensics case" button. Tools are great for speeding up the process, but you have to know what the process is. Definitely take some time to learn how to use them, but don't base your entire understanding of security on code that someone else wrote. That's how you end up as a "script kiddie", and your skills and knowledge will be limited.

Feel free to send me an ask if you have questions about any specific tool or something you found that I haven't listed. I have approximate knowledge of many things, and if I don't have an answer I can at least help point you in the right direction.

Retro computer emulation/virtualization resources

Not too long ago, it was one of my hobbies to recreate and emulate old machines and try to use them in a somewhat 'legit' way in order to experience how using them in an accurate time-period might have felt like. While it's always better to use a real machine, it's also important to note that time-accurate machines are essentially a 'ticking bomb'. Some of the electronics inside can go bad at any given time, like capacitors, and other critical components might also go bad due to humidity, moisture in the air, changes in temperature, etc. Plus, they are not always cheap and they take space that you might not have.

This is why I prefer using emulators and virtualization software in order to virtualize a time-period accurate machine that I can use. This is the software I found that I like the most, and what systems I use them for.

DOSbox-X

This is a modified version of DOSBox that includes support for multiple video devices including 3dfx emulation (Voodoo), networking, and even printer support (emulated, but AFAIK it only prints in black and white). It's perfect for MS-DOS and Windows (1-3.11) emulation. Technically you could even install Windows 95 in it.

86-box

This is the way to go if you want to emulate old retro systems. No questions. The best part of it is how flexible it is. You can select the motherboard, the processor you want to emulate, the video card, you can also enable 3dfx support up to the Voodoo 2 (but it also emulates a Voodoo3 and the Banshee), sound card, literally every detail. It's like building a PC, but virtually. And it has hardware from the old 8086 IBM PCs to more modern Pentium 2 machines. It also has network and printer support.

The downside is that since it's low-level emulation, you need a 'beefy' CPU with very good single thread performance in order for more modern systems like Windows 9x and ME to run more smoothly. Another flaw is that for some reason the FP emulation for older processors doesn't work properly for some reason, so you might prefer to use DOSBox-X if you want DOS emulation. The 3dfx emulation is also 'so-so' and not very great, but it works.

It also requires valid ROMs, but you can search for a valid ROMset online (check Github) if you want to use it. For legal reasons, I can't provide links to them, but they are not hard to find.

VMWare Workstation Player

I choose VMWare over other virtualization solutions because of it's graphic drivers capable of running relatively new games from the mid 2000s, and because unlike VirtualBox (since version 6) it still supports old Windows versions, including XP, 9x, ME and old NT systems.

Broadcom wants you to buy a license for the Pro version so they hide the links to the free Workstation Player version. But they are still available and they even release updates once in a while (yes, it's free of charge).

In the link I'm providing, go to the 'player' folder and select the latest version (higher number, now it's 17.6.1) and your system to download VMWare Workstation Player. Then go to the 'ws' folder and select the same version and system, but then select 'packages' to download a matching copy of vmware tools.

Finding software

If you need software, there are three places you need to look for. One is archive.org, the other is WinWorld PC, and the other is Vetusware (requires an account). I can't provide links so search for them on your own. I also browse sites like oldversion.com, but I don't trust these too much, so go at your own risk (or better yet, don't). Naturally you should always buy the software you use, whenever it's possible, and use backups of your legally owned software.

Did you like this post?

I will make more posts in the future about how to set up these emulated machines and how I work with them.

[sonic-wildfire]

Yooo how'd you get Windows XP in 2023, are you using some kind of VM (Virtual machine)??

Hi Maggie!

I'm using VMWare Workstation 17. I'm using a Service Pack 3 ISO that I was able to get from the Internet Archive. I can send you the link to the download page (which includes the needed serial number during OS installation) if you'd like.

I'm still trying to figure out how to get the Internet to work on the machine.

Boring Blog Episode 2

Hello ladies and gentlemen. So this unexciting blog continues my never ending waffling about computers that no-one really gives a flying fuck about.

So as I mentioned last issue. I bought a new Dell Inspiron 3525 laptop before Christmas. I ran Linux on it for two weeks and then I returned it to windows 11 which its where it is currently.

A friend asked me was I annoyed at Windows yet and to be honest I really don’t have any major issues. Do I miss Linux well lets just admit I can’t say I miss at all.

So what nonsense have I been messing with. Well as the Macintosh 128k was 40 I was going to do something Mac based. So I could have downloaded Basilisk II/Sheepshaver but nope. Mini Vmac would be appropriate given the Mac in question, once again no.

I was playing with VirtualBox trying to get it to run Mac OS 12.0 (Monterey) I was following various guides and after 5 hours of playing about I still couldn’t get it beyond the EFI boot kept failing.

I had tried many different fixes and it really wasn’t working. I then moved to VMWare Player. Originally I went to version 15 but upon changing the vmx file to apply the fix it crashed the player and refused to let it go on.

I found WMware Player could be updated to version 17 which I did and the fix allowed the installer to work. It then took forever to install. Then I let it upgrade to 12.7.3 which took another 2 hours.

This was a project I intended to be an hour ended up being over 9 hours playing with various virtual machines.

Now I have managed to install WriteRoom 3.21 on it also now considering this is a Ryzen 7 5700U system. It runs Monterey about the speed of a Pentium. You can literally type and watch the delay as the buffer updates.

So 9 hours for the slowest VM in history. That’s with it set at 8GB Ram and using 4 processor cores. Ridiculous.

Also while I was playing with emulators. I have been playing with PCSX2 (Playstation 2) emulator and have been playing most of the Burnout franchise.

It works fine but when I tried using EPSXE (PlayStation 1) what a nightmare as half of the plug-ins just refused to work.

I did try Xemu(Xbox emulator) I did try running Project Gotham 3 Racing but it wouldn’t even get above 15 frames per second making the game unplayable.

Given this is a Ryzen 7 I was thinking what the hell does it need to get it working better. My suspicion is the Vega 8 graphics card is just not up to snuff. Once again potato graphics cards used in laptops.

I was going to try Xenia (XBOX 360 emu) but given how bad the Xbox emu was I thought against it.

So one day I will get a decent desktop and run a decent video card but I am sure that’s going to be a cold day in hell before that.

Any way that’s enough waffle for now until next time … Take care

Conversion Therapy

Like Captain Hook and his temporal detectable crocodile, this graph haunts me and I hear a ticking clock when I open it.

Way back in the fall of 2020, three months before the election, the events in MAGA world were getting complex. I opened Maltego, pasted in a URL, used the Named Entity Recognition transform that accesses IBM’s Watson, and the initial graph filled with a dozen names. Now a thousand days have elapsed, there are 1,088 URLs in there, and an astonishing 2,908 names. The 5,672 entities and 13,011 links connecting them have become a sort of Rosetta stone, a thing that gets opened when reporters I know are fact checking complex flows of events.

But there’s trouble here. Maltego is a Java application and that graph is enormous. When you give Java more than 31 gigabytes of memory it switches to using 64 bit pointers and your actual usable space yield declines. If you need more than 31 gig, the next sensible number is not 32, it’s 49. A couple months ago I upped the allocated memory to 64 gig and that helped for a while. Now it really does need 80 gig if I’m going to work with that graph and pull a slice of it out in order to share with someone else.

There are other subtle problems that can’t easily be depicted in a screen shot. Twenty one Date/Time entities have crept into the graph.

And this is the real circus. There are 189 events … and an event is a child entity of … Location. They have timestamps as an internal attribute, but Maltego doesn’t really have any tools to handle temporal data.

This situation is untenable. That graph won’t work reliably on my desktop and only hardcore gamers have more capability than my setup. There are four other tools I use that can handle data relationships:

Gephi can handle a quarter million nodes in a graph but it lacks features for handling geospatial, temporal, or diverse entity data.

Graphistry is a web accessible GPU driven commercial alternative to Gephi, but with similar constraints on data types.

Tulip is an intriguing Gephi competitor, but more a framework for doing serious artwork with smaller datasets and richer network layout needs.

And that leaves Sentinel Visualizer. This is a full featured link analysis package meant for corporate fraud investigation, law enforcement, and intelligence activities. It’s Windows only, which pains me a bit, as I changed careers twenty five years ago to get out from under Microsoft’s marketing weasel driven chaos. But I think I’ve got something workable here:

So that’s Windows 10, and I’ve got it treed in a VirtualBox VM. I gave it 40 gig of memory and ten of twelve cores. I spent an evening Googling and fiddling with virtualization settings and I’ve finally got something usable in terms of speed.

Every other OS you can install in a VM, give it some resources, and it’ll just run. Windows seems to need the Guest Additions installed, a couple reboots, cursing in English and one other optional language of your choice, another install of Guest Additions, and then giving up and walking away in disgust overnight. Complete this ritual and you’ll be left with an operational system.

If this were an actual physical system we would not be having this conversation. Microsoft’s utter disrespect for the value of my time in the 1990s was intolerable and in this area I have not mellowed with age. But with a Linux host and VMware I can do essentially instant backup and restore using the ZFS snapshot feature and it’s possible to export the machine in OVA format as an offline backup.

And that's the first step data wise. I fed it an export of names, then some URLs. I'm puzzling over how to use Maltego's internal UUID with Sentinel Visualizer, without smearing an endless blur of visually very similar strings all over the display.

I have a couple projects in mind with this:

The MAGA world meltdown graph has to be either moved or abandoned.

There are a LOT of interesting datasets from Ukraine that involve both geospatial and temporal data.

There are famous historical battles that are well documented enough to make for a nice graph, but I've yet to see a source that offers both geospatial and temporal data in tabular form.

So that's the direction we're headed for the second half of 2023. If I get something worthwhile put together, I will make it available for use with Sentinel Visualizer Reader.
