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 Cheat Sheet

Bash Redirections Cheat Sheet is a convenient, one-page resource to help jog your memory for occasions when you're working with redirections in bash. There's also a nice companion blog post on the topic here. fried_green_baloney explains, "If you do use Linux/Cygwin/WSL/whatever command line, [this] is a really valuable guide to redirection."

A Free Tool

PoolMon can help you determine if you have a kernel-mode memory leak by monitoring the pool memory usage by pool tag name. Suggested by mrjailbreak, who explains that it's "from the Windows SDK/WDK package. [It’s] great for identifying memory leaks in programs!"

Another Free Tool

Jupyter Notebook is a simple, streamlined web app for creating and sharing computational documents, with support for over 40 programming languages. joeypants05 appreciates it as a means to “help work through python for those of us that are inexperienced."

A Podcast

IPv6 Buzz is another targeted offering from Packet Pushers that features a team of seasoned experts discussing IPv6-related networking, design and architecture. Kindly recommended by links234.

Yet Another Free Tool

changedetection.io is a simple, self-hosted website change detection and notification service. This open-source tool is designed as a simpler alternative to Visualping or Watchtower that alerts you to any text changes on the monitored web pages. Kindly shared by the dev, dgtlmoon123.

P.S. Bonus Free Tools

Sshuttle is a transparent proxy server for Linux/MacOS that forwards over ssh. Can be helpful for occasions when a remote network has no feasible VPN and you don't want to create an ssh port forward for every host/port on the network. Does not require admin privileges. whitewail602 likes that it "Lets you route over ssh tunnels."

BIND 9 is a versatile, flexible and full-featured name server system. This transparent, open-source DNS solution is the longest-standing and most-commonly deployed in the market. BrightBeaver adds, "Super customizable but with reasonable defaults and minimal setup required as a forwarder. It also lets you use the same service for local name resolution as on your local network, and even as as a public authoritative server."

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