Mega List of Tips, Tools, Books, Blogs & More...
Hello IT Pro,
This marks 6 months since we launched the full list on our website here. We decided to take this opportunity to celebrate with a mega list for our subscribers including all the items we've featured since then, broken down into categories. I hope you enjoy it!
First just a quick note about a problem we're working hard on at EveryCloud. Clever cybercriminals are constantly devising new ways to trick employees into sabotaging their own organizations. We read countless stories of the damage it creates—like these recently posted by frustrated sysadmins:
- "We had someone spoofing our HR dept using the .co domain. They were sending out fake job offers and asking people to send them money. Offering a 100% remote position and you just had to send in money for expenses then you would get reimbursed. Several people fell for it, one of them was really bad." —Darkace911
- "Had a user call our CEO today as she was standing in CVS ready to purchase $400 in Steam and Google Play gift cards to meet 'his' request....guess whose entire department is getting full phishing training at 9am tomorrow...." —superfoodadmin
- "My best story is simply a faculty member that ignored his first two colleagues that emailed him and said 'THIS IS A SCAM! Stop replying to him!' ... it took the third colleague to say 'Seriously? Dude. Read it.' before he thought to call.................... his secretary, to have HER call I.T. for him, to ask us if he should buy some Target gift cards just in case, because, ya know, he's already at the store so if we need them to pay our server bill this month then he could just buy them while he's there and save us some work. I facepalmed so hard that day." —r_u_dinkleberg
- "390K here to a fake bank account out of Inglewood CA. Got an e-mail about routing number updates and the woman in charge of transfers didn't even bother to verify via phone, e-mail, person, etc." —TrustyChords
Would your users will fall for such tactics?
Now on with this week's tools...
Pageant is an SSH authentication agent that makes it easier to connect to Unix or Linux machines via PuTTY. Appreciated by plazman30 who says, "It took me WAY TOO LONG to discover this one. Pageant is a component of Putty. It sits in your system tray and will let you load SSH keys into it and pass them through to putty, WinSCP, and number of other apps that support it."
NCurses Disk Usage is a disk usage analyzer with an ncurses interface. It is fast, simple and easy and should run in any minimal POSIX-like environment with ncurses installed. Recommended by durgadas as "something I install on all my Linuxes... Makes finding out sizes semi-graphical, [with] super easy nav. Good for places without monitoring—lightweight and fast; works on nearly all flavors of Unix I've needed."
AutoHotkey is an open-source scripting language for Windows that helps you easily create small to complex scripts for all sorts of tasks (form fillers, auto-clicking, macros, etc.) Automate any desktop task with this small, fast tool that runs out-of-the-box. Recommended by plazman30 as a "pretty robust Windows scripting language. I use it mostly for on-the-fly pattern substitution. It's nice to be able to type 'bl1' and have it auto-replace it my bridge line phone number."
PingInfoView lets you easily ping multiple host names and IP addresses, with the results compiled in a single table. Automatically pings all hosts at the interval you specify, and displays the number of successful and failed pings, as well as average ping time. Results can be saved as a text/html/xml file or copied to the clipboard. Thanks go to sliced_BR3AD for this one.
DriveDroid simulates a USB thumbdrive or CD-drive via the mass storage capabilities in the Android/Linux kernel. Any ISO/IMG files on the phone can be exposed to a PC, as well as any other USB thumbdrive capabilities, including booting from the drive. Can be a quick and easy option for OS installations, rescues or occasions when it helps to have a portable OS handy. Suggested by codywarmbo, who likes it because of the ability to "Boot a PC using ISO files stored on your Android phone... Having a 256GB SD full of any OS you want is super handy!"
FreeIPA is an integrated identity and authentication solution for Linux/UNIX networked environments. It combines Linux (Fedora), 389 Directory Server, MIT Kerberos, NTP, DNS and Dogtag (Certificate System). Provides centralized authentication, authorization and account information by storing data about user, groups, hosts and other objects necessary to manage the security of a network. Thanks to skarsol, who recommends it as an open-source solution for cross-system, cross-platform, multi-user authentication.
PCmover Profile Migrator migrates applications, files and settings between any two user profiles on the same computer to help set up PCs with O365 Business. User profile apps, data and settings are quickly and easily transferred from the old local AD users to new Azure AD users. Can be good for migrating data from a user profile associated with a former domain to a new profile on a new domain. Suggested by a_pojke, who found it useful "to help migrate profiles to 0365/AAD; it's been a life saver with some recent onboards."

It includes a bash shell, Autotools, revision control systems and more for building native Windows applications using MinGW-w64 toolchains. The package management system provides easy installation. Thanks for this one go to Anonymouspock, who says, "It's a mingw environment with the Arch Linux pacman package manager. I use it for ssh'ing into things, which it does very well since it has a proper VT220 compatible terminal with an excellent developer."
FastCopy is the fastest copy/backup software for Windows. Supports UNICODE and over MAX_PATH (260 characters) file pathnames. Uses multi-threads to bring out the best speed of devices and doesn't hog resources, because MFC is not used. Recommended by DoTheEvolution as the "fastest, comfiest copy I ever used. [I]t behaves just like I want, won't shit itself on trying to read damaged hdd, long paths are no problem, logs stuff, can shutdown after done, got it integrated into portable totalcommander."
Baby Web Server is an alternative for Microsoft's IIS. This simple web server offers support for ASP, with extremely simple setup. The server is multi threaded, features a real-time server log and allows you to configure a directory for webpages and default HTML page. Offers support for GET, POST and HEAD methods (form processing); sends directory listing if default HTML is not found in directory; native ASP, cookie and SSI support; and statistics on total connections, successful and failed requests and more. Limited to 5 simultaneous connections. FatherPrax tells us it's "[g]reat for when you're having to update esoteric firmware at client sites."
Bping is a Windows ping alternative that beeps whenever a reply comes in. Can allow you to keep track of your pings without having to watch the monitor. According to the recommendation from bcahill, "you can set it to beep on ping reply or on ping failure (default). I love it because if I'm wanting to monitor when a server goes up or down, I can leave it running in the background and I'll know the instant the status changes."
LDAPExplorerTool is a multi-platform graphical LDAP browser and tool for browsing, modifying and managing LDAP servers. Tested for Windows and Linux (Debian, Red Hat, Mandriva). Features SSL/TLS & full UNICODE support, the ability to create/edit/remove LDAP objects and multivalue support (including edition). Endorsed by TotallyNotIT... "Holy hell, that thing is useful."
MxToolbox is a tool that lists the MX records for a domain in priority order. Changes to MX Records show up instantly because the MX lookup is done directly against the domain's authoritative name server. Diagnostics connects to the mail server, verifies reverse DNS records, performs a simple Open Relay check and measures response time performance. Also lets you check each MX record (IP Address) against 105 blacklists. Razorray21 tells us it's an "excellent site for troubleshooting public DNS issues."
Proxmox Virtual Environment is a Debian-based Linux distribution with a modified Ubuntu LTS kernel that allows deployment and management of virtual machines and containers. Suggested by -quakeguy-, who says, "Proxmox is totally killer, particularly if you don't want to spend a ton of money and like ZFS."
Multi Commander is a multi-tabbed file manager that is an alternative to Windows Explorer. It has all the standard features of a file manager plus more-advanced features, like auto-unpacking; auto-sorting; editing the Windows Registry and accessing FTP; searching for and viewing files and pictures. Includes built-in scripting support. Reverent tells us "What I love about Multicommander is that it basically acts as a launcher for all my tools. Documents automatically open up in my preferred editor (vscode), compressed files automatically open up in 7-zip, I have a ton of custom shortcuts bound to hotkeys, and it has a bunch of built-in tools. I can even do cool things like open up consolez in the focused directory and choose to open CMD, Powershell, or Powershell 6 (portable) and whether it runs as admin or not. Oh yeah, and it's all portable. It and all the tool dependencies run off the USB."
Apache Guacamole is a remote desktop gateway that supports standard protocols like VNC, RDP and SSH. The client is an HTML5 web app that requires no plugins or client software. Once installed on a server, desktops are accessible from anywhere via web browser. Both the Guacamole server and a desktop OS can be hosted in the cloud, so desktops can be virtual. Built on its own stack of core APIs, Guacamole can be tightly integrated into other applications. "Fir3start3r likes it because it "will allow you to RDP/VNC/TELNET/SSH to any device that it can reach via a web browser....you can set up folders/subfolders for groups of devices to keep things organized - love it!!"

restic is a backup program focused on simplicity—so it's more likely those planned backups actually happen. Easy to both configure and use, fast and verifiable. Uses cryptography to guarantee confidentiality and integrity of the data. Assumes backup data is stored in an untrusted environment, so it encrypts your data with AES-256 in counter mode and authenticates using Poly1305-AES. Additional snapshots only take the storage of the actual increment and duplicate data is de-duplicated before it is written to the storage backend to save space. Recommended by shiitakeshitblaster who says, "I'm loving it! Wonderful cli interface and easy to configure and script."

Be aware this newer implementation shares no code with the original iPerf and is not backwards compatible. Credit for this one goes to Moubai.
LatencyMon analyzes the possible causes of buffer underruns by measuring kernel timer latencies and reporting DPC/ISR excecution times and hard pagefaults. It provides a comprehensible report and identifies the kernel modules and processes behind audio latencies that result in drop outs. It also provides the functionality of an ISR monitor, DPC monitor and a hard pagefault monitor. Requires Windows Vista or later. Appreciation to aberugg who tells us, "LatencyMon will check all sorts of info down to what driver/process might be the culprit. It will help you narrow it down even more. This tool helped me realize that Windows 10's kernel is terrible in terms of device latency when compared to previous versions."
GNU parallel is a shell tool for executing jobs—like a single command or a small script that has to be run for each of the lines in the input—in parallel on one or more computers. Typical input is a list of files, hosts, users, URLs or tables. A job can also be a command that reads from a pipe, which can then be split and piped into commands in parallel. Velenux finds it "handy to split jobs when you have many cores to use."
Kanboard is open-source project management software that features a simple, intuitive user interface, a clear overview of your tasks—with search and filtering, drag and drop, automatic actions and subtasks, attachments and comments. Thanks go to sgcdialler for this one!

Desktop Info displays system information on your desktop, like wallpaper, but stays in memory and updates in real time. Can be great for walk-by monitoring. Recommended by w1llynilly, who says, "It has 2 pages by default for metrics about the OS and the network/hardware. It is very lightweight and was recommended to me when I was looking for BGInfo alternatives."
True Ping is exactly the same as the standard ping program of Windows 9x, NT and 2000—except that it does a better job calculating the timing. It uses a random buffer (that changes at every ping) to improve performance. Thanks to bcahill for this one, who says, it "... can send pings very fast (hundreds per second). This is very helpful when trying to diagnose packet loss. It very quickly shows if packet loss is occurring, so I can make changes and quickly see the effect."
Parted Magic is a hard disk management solution that includes tools for disk partitioning and cloning, data rescue, disk erasing and benchmarking with Bonnie++, IOzone, Hard Info, System Stability Tester, mprime and stress. This standalone Linux operating system runs from a CD or USB drive, so nothing need be installed on the target machine. Recommended by Aggietallboy
mbuffer is a tool for buffering data streams that offers direct support for TCP-based network targets (IPv4 and IPv6), the ability to send to multiple targets in parallel and support for multiple volumes. It features I/O rate limitation, high-/low-watermark-based restart criteria, configurable buffer size and on-the-fly MD5 hash calculation in an efficient, multi-threaded implementation. Can help extend drive motor life by avoiding buffer underruns when writing to fast tape drives or libraries (those drives tend to stop and rewind in such cases). Thanks to zorinlynx, who adds, "If you move large streams from place to place, for example with "tar" or "zfs send" or use tape, mbuffer is awesome. You can send a stream over the network with a large memory buffer at each end so that momentary stalls on either end of the transfer don't reduce performance. This especially helps out when writing to tapes, as the tape drive can change directions without stopping the flow of data."
TeraCopy is a tool for copying files faster and more securely while preserving data integrity. Gives you the ability to pause/resume file transfers, verify files after copy, preserve date timestamps, copy locked files, run a shell script on completion, generate and verify checksum files and delete files securely. Integrates with Windows Explorer. Suggested by DarkAlman to "replace the integrated Windows file copy utility. Much more stable, quicker transfers, crash tolerant and adds features like 'No-to-all' and 'yes-to-all' for comparing folders."
MultiDesk & MultiDeskEnforcer are a combination of a tabbed remote desktop client (terminal services client) and a service that limits connections to only those that provide the correct shared secret (keeps hackers from accessing your server via RDP even if they have the correct password). Suggested by plazman30 as being "[s]imilar to Microsoft's RDP Manager, [b]ut doesn't need to be installed and has tabs across the top, instead of the side."
The PsTools suite includes command-line utilities for listing the processes running on local or remote computers, running processes remotely, rebooting computers, dumping event logs, and more. FYI: Some anti-virus scanners report that one or more of the tools are infected with a "remote admin" virus. None of the PsTools contain viruses, but they have been used by viruses, which is why they trigger virus notifications.

Magic Wormhole is a service for sending files directly with no intermediate upload, no web interface and no login. When both parties are online you with the minimal software installed, the wormhole is invoked via command line identifying the file you want to send. The server then provides a speakable, one-time-use password that you give the recipient. When they enter that password in their wormhole console, key exchange occurs and the download begins directly between your computers. rjohnson99 explains, "Magic Wormhole is sort of like JustBeamIt but is open-source and is built on Python. I use it a lot on Linux servers."

Here are a couple handy Windows shortcuts:
Win + Shift + S: Captures a user-selectable area of the screen to the clipboard (on Windows 10 Ver 1703+)
WIN + CTRL + F4: Close a virtual desktop
Here's a shortcut for a 4-pane explorer in Windows without installing 3rd-party software:
Win + E, win + left, up
Win + E, win + right, up
Win + E, win + left, down
Win + E, win + right, down
(Keep the win key down for the arrows, and no pauses.) Appreciation goes to ZAFJB for this one.
Our recent tip for a shortcut to get a 4-pane explorer in Windows, triggered this suggestion from SevaraB: "You can do that for an even larger grid of Windows by right-clicking the clock in the taskbar, and clicking 'Show windows side by side' to arrange them neatly. Did this for 4 rows of 6 windows when I had to have a quick 'n' dirty "video wall" of windows monitoring servers at our branches." ZAFJB adds that it actually works when you right-click "anywhere on the taskbar, except application icons or start button."
This tip comes courtesy of shipsass:
"When I need to use Windows Explorer but I don't want to take my hands off the keyboard, I press Windows-E to launch Explorer and then Ctrl-L to jump to the address line and type my path. The Ctrl-L trick also works with any web browser, and it's an efficient way of talking less-technical people through instructions when 'browse to [location]' stumps them."
Clear browser history/cookies by pressing CTRL-SHIFT-DELETE on most major browsers.
Thanks go to synapticpanda, who adds that this "saves me so much time when troubleshooting web apps where I am playing with the cache and such."
To rename a file with F2, while still editing the name of that file: Hit TAB to tab into the renaming of the next file.
Thanks to abeeftaco for this one!
Alt-D is a reliable alternative to Ctrl-L for jumping to the address line in a browser.
Thanks for this one go to fencepost_ajm, who explains: "Ctrl-L comes from the browser side as a shortcut for Location, Alt-D from the Windows Explorer side for Directory."
Browser shortcut: When typing a URL that ends with dot com, Ctrl + Enter will place the ".com" and take you to the page.
Thanks to wpierre for this one!
This tip comes from anynonus, as something that daily that saves a few clicks:
"Running a program with ctrl + shift + enter from start menu will start it as administrator
(alt + y will select YES to run as admin) ... my user account is local admin [so] I don't feel like that is unsafe"
Building on our PowerShell resources, we received the following suggestion from halbaradkenafin:
aka.ms/pskoans is "a way to learn PowerShell using PowerShell (and Pester). It's really cool and a bunch of folks have high praise for it (including a few teams within MSFT)."
Keyboard shortcut: If you already have an application open, hold ctrl + shift and middle click on the application in your task bar to open another instance as admin.
Thanks go to Polymira for this one.
Remote Server Tip: "Critical advice. When testing out network configuration changes, prior to restarting the networking service or rebooting, always create a cron job that will restore your original network configuration and then reboot/restart networking on the machine after 5 minutes. If your config worked, you have enough time to remove it. If it didn't, it will fix itself.
This is a beautifully simple solution that I learned from my old mentor at my very first job. I've held on to it for a long time."
Thanks go to FrigidNox for the tip!
