IT Pro Tuesday #250

Get this in your inbox each week.

Welcome back to IT Pro Tuesday!

To start off this week, we've got a followup related to last week's PowerShell Wargames. Reports are that the Slack link at Under the Wire isn't working. But thanks to siftekos, we can share that the servers are up, and the username/password combo of century1/century1 appears to work for the rooms. 

The latest episode of the Security Swarm Podcast: "The Reemergence of Emotet and Why Botnets Continue to Return," features a discussion with Umut Alemdar, Head of Security Lab here at Hornetsecurity, about the reemergence of Emotet and the pervasiveness of botnets. Why do they keep coming back?

We're looking for your favorite tips and tools we can share with the community... those that help you do your job better and more easily. Please reply or leave a comment with your suggestions, and we'll be featuring them in the coming weeks.

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

A Tutorial

Everything you always wanted to know about optical is an updated version of the popular tutorial aimed at network engineers. Covers all the basics of how fiber works, plus details on how to select, install and maintain it. Kindly sugested by notFREEfood, "a fan of Richard Steenbergen's NANOG talk on [fiber]." Slides here.

A Website

9to5Linux is a comprehensive online resource that covers the latest news, reviews, and tutorials in the world of Linux and related open-source software. Provides up-to-date information on the most-recent Linux distributions, software updates, security patches, and more. Our appreciation for the recommendation goes to damn_the_bad_luck.

A Free Tool

Far Manager is a text mode tool that helps you manage files and archives in Windows. Provides a simple, intuitive interface for viewing files and directories; editing, copying and renaming files; color highlighting and sort groups and more. Multi-language, easily configurable and extensible via a library of plugins. Appreciated by Hel_OWeen.

Another Free Tool

NAV (Network Administration Visualized) is a device/vendor-agnostic monitoring program that features a customizable dashboard, extensive statistical overviews, on-the-fly configuration as well as full traceability of users and equipment. Our thanks for this one go to oyvindlw.

Training Resource

Oh Shit, Git!?! is designed to help you get out of the sort of messes that Git makes it easy to get into. Offers plain-language explanations of various problems and how they were resolved, which makes it possible to find answers without knowing the official name of whatever specific issue(s) you need to understand. BlameDNS_ raves, "Love the ohshitgit."

P.S. Bonus Free Tools

ImageMagick is an open-source tool for manipulating digital images, with a command-line interface for executing complex image processing tasks. Can be used to create, edit, compose or convert BMP images, and supports a variety of file formats, including JPEG, PNG, GIF, TIFF, and PDF. LoopVariant recommends it "for CLI image manipulation."

Zimbra Open Source Edition enables you to automate and simplify communication between any workgroup, whether public or private. Handles delivery, storage and dispatch of e-mail, indexing, server logging, directory service and more. Supports IMAP, POP, CalDAV, CarDAV and syncs with Android, iOS and Windows. squishfouce explains, "Zimbra is a great open source Exchange alternative that I believe Comcast still actively uses for email access."

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