Welcome back to IT Pro Tuesday!
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 with your suggestions, and we'll be featuring them in the coming weeks.
And as always, we’re updating the full 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 Tutorial
Understanding Load Balancing on Network Devices explores why total bandwidth is not always increased by implementing a port-channel and clarifies how load balancing really works on most network devices. cyberentomology recommends it as a "great rundown of why a portchannel/LAG made up of two 10G links is not the same as a 20G link, which is a commonly held misconception about link aggregation."
A Script
Automating with PowerShell: Disabling application consent on all tenants walks you through how you can get additional options for your automations by shutting off application consent (without MSOL) and then run that on all your tenants. Lime-TeGek explains, "Microsoft is removing MSOL support in March, so I figured we'd get an earlier start than most on having a replacement in place."
A Tip
InvisibleTextArea explains an easy way to keep your AD clean: "Automation. HR has a personnel database with a web front end. Our onboarding and off-board scripts hook into that and do the needful. This also has the happy outcome that you can deflect any 'Why is <user account> not setup/deleted/disabled/etc.' queries to 'Go speak to HR/Line Manager/Head of Department.'"
Training Resource
Free CCNA 200-301 - Complete Course 2021 is a full CCNA video course from Jeremy's IT Lab that covers everything you need to pass the latest version of the CCNA exam (exam code 200-301). Whether you're actively pursuing certification or just interested in understanding the concepts, this is a great free sysadmin resource. Kindly suggested by Dark_Nate.
Another Tutorial
Reset Windows 10 Local Admin Password with Command Prompt provides a nice solution for occasions where you've forgotten/don’t have the password or need to change it. Explains how to quickly reset the password via command prompt whether logged in or logged out. Kindly shared by Tymanthius.
P.S. Bonus Free Tools
Wiki.js is a powerful, extensible open-source Wiki software that works on virtually any platform. Comes bundled with a wide range of modules that can be turned on/off on demand. Fast, secure, customizable, scalable and compatible with PostgreSQL, MySQL, MariaDB, MS SQL Server or SQLite. Credit for this one goes to sysacc.
Scapy is a powerful, interactive Python2/3 packet-manipulation program that can forge or decode packets for a wide array of protocols, send & capture them, match requests with replies and more. Easily handles tasks like scanning, tracerouting, probing, unit tests, attacks and network discovery so it can replace hping, most of nmap, arpspoof, arp-sk, arping, tcpdump, tshark, p0f, etc. Also performs specific tasks most other tools can’t handle, like sending invalid frames, injecting your own 802.11 frames and combining technics. Our thanks for this suggestion go to lazyjk.
Have a fantastic week and as usual, let us know any comments.
