Hello IT Pro,

Welcome back to IT Pro Tuesday!

To start off—just a quick note to lookout for a rising cyberthreat trend known as leakware/ransomware hybrid attacks. If you're unfamiliar, you can learn more here.

This week, we’re looking for your favorite blogs to share with the community. Please let us know those that help you do things more easily so you get better at your job!

As always, we’re updating the full, searchable list on our website here. Enjoy.

But on with this week's tools...! Here are the most-interesting items that have come across our desks, laptops and phones this week. Hornetsecurity has no known affiliation with any of these unless we explicitly state otherwise.

A Free Tool

PumpKIN is an open-source, fully functional TFTP server and client that's helpful for maintenance of network equipment and transferring files over an ntalk connection. Reverent finds it "very useful for soft-bricked devices, unifi comes to mind."

A Tip

A time saver, compliments of thecravenone:

You can use carets ( ^ ) to find and replace [first occurrence] on the command line. I mostly use it for typos

cat /home/madmin/file.txt


# /home/admin/file.txt gets cat'd


Another Free Tool

netpalm offers scalable API access into your network. It makes it easy to push and pull state from apps to network by providing multiple southbound drivers, abstraction methods and modern northbound interfaces such as open API3 and REST webhooks. Allows you to bring your own jinja2 config, service and webhook templates, python scripts and webhooks for quick adoption into your existing devops workflows. Thanks to onefst250r for the suggestion.

A Blog

The Geek Stuff is where software engineer Ramesh Natarajan posts instruction guides, how-tos, troubleshooting tips and tricks for Linux and open-source technologies. Focuses on educational content and problem resolution.

A Podcast

Daniel and Jorge Explain The Universe is an entertaining exploration of the unanswered scientific questions that have fascinated mankind for centuries. In each episode, Daniel Whiteson (a CERN Physicist) and Jorge Cham (an online cartoonist) discuss mind-bending topics in a light, conversational way that's fun and enjoyable. PcPimp recommends it to the tech-interested, "It's not IT related, but it's a good science podcast."

P.S. Bonus Free Tools

Paint.NET is a Windows image and photo editing application with an intuitive GUI and support for layers, unlimited undo, special effects and more. An active online community offers support, instructions and plugins. OhkokuKishi likes it for "light image editing, mainly for screenshots in documentation."

VyOS is an open-source network OS that will run on a wide range of hardware, virtual machines and cloud providers. Offers nice features for both small and large networks. Cheeze_It likes it as a "free/open source router operating system."



Have a fantastic week and as usual, let us know any comments.
