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 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 Free Tool

croc is a simple, secure way for any two computers to connect and transfer files and folders. This cross-platform CLI tool enables data transfer using a relay, with end-to-end encryption and ipv6-first with ipv4 fallback. Allows multiple file transfers, resuming transfers that are interrupted, ability to use a proxy like tor, and no need for local server or port forwarding. first_byte lists it as a favorite for "CLI peer-to-peer file transfer."

A Cheatsheet

Exim Cheatsheet is a nicely organized, text-based list of useful Exim commands, all kindly compiled and shared by DevOps Engineer Brad "the Mad." Our appreciation for directing us to this resource goes to IAmTheM4ilm4n, who likes to keep it handy "because I can never remember the commands in Exim."

Another Free Tool

ClipX is a simple program that supercharges your standard 1-item Windows clipboard so it can hold up to 1024 items, including text snippets, urls and bitmap images. The full list of copied elements is easily accessible from the system tray. Appreciation for this one goes to DerSteamboy.

Yet Another Free Tool

Boto3 is the AWS-maintained Software Development Kit for Python that allows Python developers to write their own software to leverage AWS. Makes it easy to integrate Python applications, libraries or scripts with Amazon services like S3, EC2 and DynamoDB. yankdevil considers it "indispensable."

One Last Free Tool

Scanner is a tool that employs a sunburst chart to graphically represent your hard disk usage. Allows you to see a representation of all major files and folders from all directory levels at a glance. GWSTPS recommends it "for individual server stuff… tiny, fast, free way to see what's taking up disk."

P.S. Bonus Free Tools

uBlock Origin is an open-source, content-filtering browser extension that's designed to eliminate privacy invasion without compromising user experience. It's not just an ad blocker, but rather a wide-spectrum content blocker that prioritizes CPU and memory efficiency. Available for Chrome, Chromium, MS Edge, Opera, Firefox and all Safari releases prior to 13. Thanks for the suggestion go to dcraig66.

CurrPorts is a network monitoring tool that shows all the TCP/IP and UDP ports that are currently open on your computer, with details about the process that opened each port—including name, full path, version information, time it was created and who created it. Automatically flags suspicious ports owned by unidentified applications and allows you to manually close unwanted TCP connections, kill any process that opened a port, and save port information to HTML, XML, or tab-delimited text files. Digitaldarragh includes this among "the applications I couldn't do without."

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