  • Bug Bounty Hunting 101: An Introduction for Beginners
    Practice: Set up simple networking labs using tools like Cisco Packet Tracer or GNS3. - Source: dev.to / 11 days ago
  • Where do I go from here?
    If you mean a Cisco 2950, I guess you want to learn Networking. So a good place to start is to run GNS3 (https://gns3.com). You can download a VM image and run that, that's what I do. GNS3 is a great learning tool and you can use both real (your 2950) and virtual devices to make networks. Source: 8 months ago

    GNS3 is the software your looking for it can be found here https://gns3.com let me know if you could use some resources on it. Source: 12 months ago
  • What skills are great to learn in a home lab for a beginner in IT ?
    GNS3 is a network device emulator, and more than a few devices requires lots of CPU and RAM resources. You need to pay for a licence for each device you want to emulate. Source: over 1 year ago

  • Failed to connect to the host via SSH on Ubuntu 22.04
    If you have just upgraded to Ubuntu 22.04, and you suddenly experience either errors when trying to ssh into hosts, or when running ansible or again when running the ansible provisioner building a packer image, this is probably going to be useful for you. - Source: dev.to / over 1 year ago
  • Create a minimalist OS using Docker Containers and Hashicorp Packer
    I am already using Hashicorp Packer at work and for personal projects and I wanted to test This idea out by wrapping it a single Packer Template file. This reduces the level of maintaining a lot of small scripts, Dockerfiles and configurations and the user can simply trigger a couple of Commands to get a minimalist OS at the end of the process. - Source: dev.to / over 1 year ago
  • After self-hosting my email for twenty-three years I have thrown in the towel. The oligopoly has won.
    And while it is a slight increase in complexity, it can be an overall net gain in functionality, configurability and reliability. Much like Packer is far more reliable and practical than manually making VM images sitting in front of a terminal, even though making the initial configuration takes some time.

  • Customized Ubuntu Images using Packer + QEMU + Cloud-Init & UEFI bootloading
    Hashicorp Packer provides a nice wrapper / abstraction over the QEMU in order to boot the image and use it to set it up on first-boot. Instead of writing really long commands in order to boot up the image using QEMU, Packer provided a nice Configuration Template in a more Readable fashion. - Source: dev.to / almost 2 years ago
  • The journey of sharing a wired USB printer over the network
    Packer seemed like the perfect tool for the job. I have never used it before and wanted to get familiar with the tool. It doesn't come with ARM support out of the box, but there are two community projects to fill that niche. - Source: dev.to / about 2 years ago
