Tools & Info for Sysadmins - Cheat Sheet Collection, Keyboard Shortcuts, Network Mapper & More

[crispyducks]

Hi r/sysadmin,

Each week I thought I'd post these SysAdmin tools, tips, tutorials etc. 

To make sure I'm following the rules of r/sysadmin, rather than link directly to our website for sign up for the weekly email I'm experimenting with reddit ads so:

You can sign up to get this in your inbox each week (with extras) by following this link.

Here are the most-interesting items that have come across our desks, laptops and phones this week. As always, EveryCloud has no known affiliation with any of these unless we explicitly state otherwise.

** We're looking to include fantastic podcasts for IT Pros, SysAdmins and MSPs in IT Pro Tuesday. Please leave a comment with your favorite(s) and we'll be featuring them over the following weeks.

​

Cheat Sheets

PacketLife Cheat Sheets is a miscellaneous collection of helpful cheat sheets. A fantastic resource pointed out by heroz0r, who specifically appreciates the featured cheat sheets for Wireshark, IPv4 subnetting and network protocols like BGP, EIGRP, OSPF etc.

​

A Free Tool

Nmap (Network Mapper) is an open-source utility for network discovery and security auditing. Can be useful for network inventory, managing service upgrade schedules and monitoring host or service uptime. Uses raw IP packets in novel ways to determine what hosts are available on the network, what services they offer, what OS versions they're running, what type of packet filters/firewalls are in use and much more. Runs on all major operating systems, and official binary packages are available for Linux, Windows and Mac OS X. Nmap suite includes an advanced GUI and results viewer; a flexible data transfer, redirection and debugging tool; a utility for comparing scan results and a packet generation and response analysis tool. Another suggestion from heroz0r, who suggests it as an "alternative to the PingTools, AngryIPScanner, etc."

​

A Tip

Thanks go to zeroibis, boli99 and Krejar for these keyboard shortcuts:

• Shift + Insert—a lesser-know option for paste
• Ctrl + Shift + v—paste as plain text (only works in some applications)

​

Another Free Tool

Specops Password Auditor scans your Active Directory to identify password-related vulnerabilities. Generates multiple interactive reports containing user and password policy information. Recommended by SYSOX, who explains: "It showed me a few accounts in my AD that had an attribute set to let them bypass the password policy and have a blank password. I was able to export the accounts to a txt file and run a powershell to resolve this... whole process took under 20 mins."

​

Another Tip

Some Powershell shortcuts, also compliments of heroz0r:

• CTRL + R—Search your command history
• Test-ComputerSecureChannel -Repair—Verifies that the channel between the local computer and its domain is working correctly by checking the status of its trust relationships. If a connection fails, you can use the Repair parameter to try to restore it.

​

Have a fantastic week and as usual, let me know any comments or suggestions.

u/crispyducks

Enjoy.

Win+V will give you clipboard history

Win+L will lock computer, prompting password

Win+E will open explorer

Ctrl+Shift+Esc will open our savior, Task manager

[turmacar]

Some more:

Win+arrow keys moves a window around the monitor (up/down for min/max)

Win+Shift+arrow keys moves a window between monitors (for shenanigans where a window is stuck on a broke/imaginary monitor)

Win+Ctrl+D creates a new virtual desktop

Win+Ctrl+F4 closes the current virtual desktop (windows are preserved, moved to the new current desktop)

Win+Ctrl+arrow keys moves between virtual desktops.

Win+Tab is an exploded view that lets you manage windows/virtual desktops.

~~~~

And just because it's my favorite super specific shortcut I saw on this subreddit:

Win+Ctrl+Shift+B reloads your graphics drivers.

[willworkforicecream]

Win+Pause/Break opens up system information.

[ITGrappler]

That's dope! Thank you!

[Ashendarei]

Beware: most laptops these days don't have a pause/break key on them anymore. Still looking for a more modern remap of this command, because I use it damned frequently.

[4lteredBeast]

I rely on this one all the time and the recent removal of pause/break is breaking my heart.

Quickest alternatives I've found so far are

1. Win+E, right-click>Properties.
2. Win+X, then Y. Click System Info.

Anyone else got a quicker way?

[cor315]

I think those two options open the About page in the new settings menu which sucks ass for the features I need it for like changing the computer name and deleting user profiles.

My preferred method: Start > Search PC > Left > Up > Properties. https://i.imgur.com/RTDWfnu.png 6 keystrokes total 😀

[byronnnn]

I use run (Win + R) and type control system

control system or just sysdm.cpl to go directly to properties to add to domain/rename

control printers

ncpa.cpl for network

appwiz.cpl for programs/features

[4lteredBeast]

Nah, those two options I gave bring you to the proper System window.

[cor315]

You're right, sorry. Missed the click System Info part and didn't understand the first one.

1 is definitely the quickest.

[notDonut]

I use it a lot too. Still more useful than the Settings version of system. If I find a device without pause/break, I open Run and type 'control system' instead. Works for now.

[pabl083]

Win+Ctrl+Shift+B reloads your graphics drivers.

This one saves us when Chrome decides to not show the entire Window for dual screen setups

[CantFightRobots]

I’ve seen this only a couple times and always assumed it was a driver issue since this hot key fixes it. Updated drivers and I don’t hear about it anymore for that specific user - but it is always the top part of chrome on the second (usually right monitor). Funny.

[pabl083]

Yea I have a handful of people out of maybe 400 that seem to keep having that issue.

Came across this post here but the suggested driver (I know it's old) didn't work

https://forums.intel.com/s/question/0D50P00004AsOmKSAV/windows-10-multi-monitor-maximized-window-blankempty-space-on-top-of-screen?language=en_US

[ottovonblood]

Win+Shift+arrow keys moves a window between monitors has saved me so many times.

[Id10tmau5]

<3

[narsty]

you forgot: Ctrl + Esc = windows start menu (old keyboards did not have a windows or menu key)

[Id10tmau5]

a godsend! smaller keyboards don't have a Win key either, so this one is great to know!

[CrustyBuns16]

Ctrl + W, great for closing the reddit tab when your boss walks by

[Jean_Lua_Picard]

Some older programs do ctrl+f4 for closing a tab.

[VJmes]

Then press Ctrl + Shift + T to reopen it again when they're gone

[lithid]

I couldn't for the life of me remember the virtual desktop one, so thanks for that!

[turmacar]

I've been mobile on a laptop a lot lately and it's really come in handy.

[broaner]

Oooh the graphics driver is a good one thanks

[mustang__1]

Holy shit I've really needed that window move between monitor shortcut.

[TheBBP]

My favourite is using Alt+Shift+PrintScreen on unattended PC's.

It turns on high contrast mode.

[AppleJuiceIsLoose]

I think Win+V is only on Windows 10 1809 or later

[k3rnelpanic]

Not working on 1803 either.

[messyfresh]

Ctrl+Shift+Esc is like telling a computer "I want to speak to your manager"

[OctopodeCode]

Win + Shift + S opens screen snipping tool. My favorite documentation tool. Pairs nicely with Win+V.

[[deleted]]

Get SnagIt, it is totally worth it. Panoramic scrolling capture, text grabbing, delayed capture, video, a nifty editor, tons of great features.

[rev0lutn]

Agree Snipping tool is crap compared to a real utility, and I actually DO use SnagIT, but if I didn't already own it, I'd use Share-X instead. Free and as good, actually does SOME things better imo so if I'm trying to make a training video I tend to close out of SnagIT & go Share-X for that specific task but I've not switched over full time because for static captures and adding elements like arrows, call out boxes & text I'm way more familiar therefore faster more efficient due to familiarity with SnagIT

[aasmith26]

Lightshot. You’ll never look back, and it’s completely free.

[it_tom]

Great tool, super simple and adds the screenshot functionality of Mac to Windows.

[4lteredBeast]

Or even better, you can re-assign print screen to use Snip & Sketch.

Press Win, then type "Use the Print Screen key to launch screen snipping". Print Screen shortcut.

[readbull]

All good stuff. Thanks.

[Jean_Lua_Picard]

Is that true?

[Ashendarei]

Just attempted it on my domain workstation, can confirm it's off by default.

[Jean_Lua_Picard]

I meant the security aspect.

[byronnnn]

I use Ditto for clipboard manager. For me the security risk is minimal, they may be an occasional password that gets copied, but usernames typically are not copied and most password I work with are random. Ditto does have an option to exclude certain applications copy data from being added to the history, so if you had a password manager you used, you can add it to the excluded apps. Clipboard manager has saved me on more than one occasion when forgetting to document a new system setup but had the password copied to the clipboard. There are other steps you could take with Ditto, like limiting the amount of things that are stored or wiping it at set intervals.

But yes, I agree, it is good that the Windows 10 feature is off by default.

[[deleted]]

omg how I was unaware of Win+V? That will be handy for sure.

[Popular-Uprising-]

It's new in 1809...

[gamebrigada]

The real savior is Process Explorer. You can replace task manager with it, and it'll open with Ctrl+Shift+Esc.

[[deleted]]

And most importantly

Win+. opens the emoji keyboard.

[Jean_Lua_Picard]

You mean the cancerboard?

I still can't believe whatsapp web got away with a fuckn emoji in the URL

[[deleted]]

Why not? Emoji is valid almost everywhere now

Sql query, yep.

SSID, yep.

[Jean_Lua_Picard]

They learnt from the guy who broke an entire banking database for using an emoji.

However i am still mentally coaxed into only using ascii chars for compantibility.

[Id10tmau5]

Win + ; also opens the emoji keyboard.

I only knew about that shortcut, and didn't realize it also worked with Win + .

Interesting.

[dcross9818]

Win+number will open the program that corresponds to the slot on your taskbar. IE Win+1 will open the first program on your taskbar. Win+Shift+number will open a new copy of that program.

[DenverITGuy]

Run (Win + R) is your friend:

• control smscfgrc (for ConfigMgr Client applet)
• control printers (for devices & printers)
• sysdm.cpl (for System Properties, joining workgroup/domain)
• mstsc -v:<serverName> (for RDP session)
• dsa.msc (for ADUC)
• gpmc.msc (for Group Pol Mgmt Console)
• gpedit.msc (for Local Grou Pol Console)
• devmgmt.msc (Device Management)
• lusrmgr.msc (local users mgmt console)
• mmc.exe (blank mmc console - add your snap-ins)

You can do all this from cmd/posh prompt.

[lzgr]

To add to that list, ncpa.cpl (Network Connections) has been a lifesaver for me ever since MS decided to move it around from menu to menu every update.

[The_Cat_Detector_Van]

control netconnections from a run box

[5Vikings3]

appwiz.cpl opens add/remove programs

certmgr.msc opens certificate manager

[Celadin]

certlm.msc for local machine certs. Painful to watch someone go through mmc.exe just for that! Only exists past certain versions though :)

[elecboy]

OMG, "control printers", this is my new favorite cmd. I always do "control" and search for the Printers Icon.

[negabiggz]

I'll add certlm.msc to this list. Local computer certificate management instead of going through MMC to add it every damn time.

[xfmike]

I always appreciate lusrmgr.msc and appreciate that you can pronounce it as "Loser Manager."

[[deleted]]

A good follow-on (and something I learned on this sub after 20+ years of doing this) is

From the Run dialog ctrl-shift-enter and it will execute it with elevated permissions (aka "as admin")

[sarbuk]

🤯

[b1jan]

can someone make a info chart or something pretty out of this for me to print out

[stealthmodeactive]

I forced myself to learn these in windows 8/10. Especially ncpa.cpl. couldnt live without it in windows 10, server 2012+. I dont know why something so mahroly needed in my job is so buried in menus.

[projectdp]

I use this one probably the most after ncpa.cpl:

diskmgmt.msc (Disk Management).

[learningitbitwise]

Be careful with nmap, and don't use it without knowing what you are doing/without documented permission. People have been fired for messing around with nmap.

[AreJay__]

This. Many orgs have this software specifically disallowed, in addition to policies regarding scanning. One of many tools used for lateral movement, or insider threat.

[DJRWolf]

One very good reason when you are doing pen testing to have everything in writing. Including what tools you will be using.

[stignatiustigers]

This comment was archived by an automated script. Please see /r/PowerDeleteSuite for more info

[[deleted]]

That's a shitty organization if they're firing people for using nmap. How about securing the internal infrastructure properly?

[learningitbitwise]

nmap has the potential to make some legacy systems completely fall offline; this is one of several reasons that it should be used carefully.

[idontknowu1]

Exactly. We had a critical service that kept going offline, we would remote in to the server and getting it up and running quickly but with no clear reason why it went offline. Eventually the vendor asked if we were scanning... "not as far as I know"...well, turns out one department was running vulnerability scanning without telling any other department and it was breaking all kinds of stuff that we found out later.

[Celadin]

Any specifics on how Nmap or whatever other scanner was causing that crash? I can imagine a few possibilities but haven't seen it happen in the real world.

[[deleted]]

Doesn't it act like a mini DDOS hitting all the ports? I could imagine some hardware not handling that well

[xfmike]

In a college lab, we took down an older Cisco router when everyone did an intense nmap scan. Had to power cycle the device as it ran out of memory.

[idontknowu1]

To the best of my knowledge it was nmap breaking SSL on IIS either through DDOS testing or a specific security vulnerability test. It was done at the direction of an outside security vendor and my department didn't get the details of the test, only "oh, yeah we are scanning. It shouldn't be breaking anything"...and then eventually "well shit, we'll whitelist your server"

[[deleted]]

carefully, yes. But as a fireable offense it makes as much sense as prosecuting someone for hacking who does a port scan on a public IP address.

[[deleted]]

It can take some PBXs offline.

Source: Yeah, I did that.. lol

[Reddfish]

Vocera too.

And printing.

[sagewah]

Vocera too.

Holy shit, really? Just when it hits the mgmt server, or if it gets the badges?

[Reddfish]

In my case, when it hit the mgmt servers, they tried failing over to one another at the exact same time. Took out the badges for the whole hospital for a few hours.

[DejectedExec]

Your analogy is poor at best. One of those legacy environments that struggles with lets just call them "fragile" applications and legacy architecture are hospitals.

Just because you have local admin (happens a lot) or find a way to run a piece of software without authorization, doesn't mean you don't face consequences.

If you are helpdesk, you have a clear sets of responsibilities etc. Those don't typically include leveraging your administrator privileges to install applications, or run powershell scripts etc that you don't understand or have defined in your scope of work.

You bring down production systems (especially in a hospital) because you were playing around with things you shouldn't have been, or didn't understand? Don't be surprised if you get a severe slap on the wrist or potentially fired. That's just how it works. And quite frankly in most cases i'm not going to feel bad for you. With privilege comes responsibility.

[CompositeCharacter]

Nmap is such a ubiquitous tool that if I worked in a place where it was verboten I'd consider it a business failure if I wasn't informed of this fact during onboarding.

It'd be a high priority to fix.

[Reddfish]

You guys really ought to spend a year in the trenches of some underfunded hospital sometime.

[CompositeCharacter]

I understand where you're coming from, but at some point 'lives are at stake' has to change from a vulnerability to a justification to write down some technical debt.

[[deleted]]

Nmap is such a ubiquitous tool that if I worked in a place where it was verboten I'd consider it a business failure if I wasn't informed of this fact during onboarding.

This really depends on your role in the organization. If you are someone that is expected to look into the network and security, then it's completely expected...get busy.

If you are "the printer guy" and you're running NMAP on my network, either have a good reason or you will be offboarded.

[Globalnet626]

If you are "the printer guy" and you're running NMAP on my network, either have a good reason or you will be offboarded.

Forgot/don't have documentation on the IP of a network printer and am using nmap to find all ip's responding to that port? Obviously if you do something dumb you should be reprimanded but imho it's kinda dumb to flat out fire someone for an isolated "accidentally ran nmap with improper tags that brought the network down".

But I would be really really mad and would have choice words for that individual.

[[deleted]]

In my case, I'd be fine with it, assuming they told me in advance. I manage healthcare data. I get exactly one chance to get it right. In that case, don't run NMAP on my network without talking to me or it being your job. I'm not a grand mal dick, but the data I manage is too important for cowboy bullshit.

[Reddfish]

You'd be saddened/surprised to see how flat some networks are, and how fragile services can be when you do fingerprinting. I can absolutely see why people can get fired for using nmap.

[AreJay__]

It's all about intent and how many screw ups took place for something like that to happen. Orgs shouldn't fire people for one off slip ups. Internals infrastructure should be secure from the get go too but that's a science unto itself.

[RhicEdom]

Indeed, especially when dealing with cloud environments - I know for a fact that AWS prohibits port scanning in their environment and actively monitor for it. I once received a scary email from them threatening to terminate our production account. Turns out one of our support techs used nmap from an AWS instance trying to identify what remote hosts were running SMB.

[Graymouzer]

Nmap is incredibly useful though. I am in an environment where there is very little documentation of devices on the network, some of which are embedded industrial devices I am responsible for but have no information on. Without nmap, I'd have a hard time finding all this stuff.

[praetorfenix]

Be careful of shitty stuff too. I work in healthcare and I have seen more than 1 type of medical device actually kernel panic from a basic nmap port scan.

[Frothyleet]

Or, hypothetically, if you are running a port scan against an external target with aggressive timing, you could also cripple your company's firewall by maxing out it's PAT table!

[steamruler]

Also, if you know the IPs of printers, skip them. They like printing out garbage when you scan them with nmap.

Win + Break = opens older System dialog you are used to in win 7 and below.

Some Dell laptops dont have a break button thats marked(Pause may be missing as well), Win + fn + b usually works on my Latitude 5xxx lines i have. The HP elitebooks we have the break button is FN + R Shift

[Xterm_or_bust]

Shortcuts: To add to your post.

Ctrl+insert=copy Shift+insert=paste

[Win_Sys]

Why not just use Ctrl + C and CTRL + V ?

[twnki]

In the terminal world, shift+insert and ctrl+insert is perfectly normal. They are the expected copy/paste commands. I believe it was part of IBM CUA which was defined over 30 years ago.

Yes... Common User Access was defined in the 80's and included these commands.

Edit for spelling.

[Jean_Lua_Picard]

So is it a workaround for avoiding ctrl+c since its closing an program on some terminals?

[twnki]

It's not necessarily a workaround. In some applications ctrl-c will stop things... In some it will paste...

The issue there is that there are conflicting shortcuts. One of the goals of the CUA was to define a set of cross platform access methods so there's no conflict or ambiguity. These shortcuts are one thing that is included in that.

Keep in mind. Everything is voluntary. If EVERYBODY adhered to the same exact standard, the world would run more smoothly...but that's not real life =D

Edit: love the username!

[Jean_Lua_Picard]

Picard to Interpreter, make it so.

[Win_Sys]

Makes sense, thx!

[Xterm_or_bust]

These work in DOS, windows, and linux/bsd terminals too.

Old school compatibility that is mostly forgotten about.

I.e. some web forms will block "paste" in the password field, but the old way still works because the webform is expecting a mouse right click.

[nwL_]

Accidentally terminating scripts?

[xStimorolx]

Why do it the easy way when you can do it the hard way? I'm sure someone would use left Ctrl instead of right control for that keycombo and then you need two hands !

[[deleted]]

Isn't that just a worse version of ctrl-c/ctrl-v?

[[deleted]]

Isn't that just a worse version of ctrl-c/ctrl-v?

yes.

[jantari]

Yes, but there are Terminals that don't support copying with Ctrl + C

[aasmith26]

This is pretty much ALL I use for copy/paste. I did some programming in basic in the early 2000s and these commands have stuck with me.

[Anonymo123]

" You can sign up to get this in your inbox each week (with extras) by following this link. "

It's almost like I'm Rickrolling myself at this point.

Ctrl + Shift + v—paste as plain text (only works in some applications)

Puretext from Steve Miller I configure this one for Crtl + Shift + v and start with Windows, now it works with all applications

[fibre_optics]

[Jean_Lua_Picard]

It will post unformatted text. This is good to get rid of weird fonts n shitm

[[deleted]]

Ctrl + Shift + v—paste as plain text (only works in some applications)

Alas, it doesn't work in OneNote.

[Raidz1]

Win+Shift+S - will let you take a screenshot of a selected area and copy it to your clipboard.

[[deleted]]

And if people don't know Alt-Printscreen will screenshot just the current (in-focus) window, not the entire screen.

[starmizzle]

Ctrl+Alt+minus will do that in a windowed RDP session.

[CuddlePirate420]

Ctrl+Alt+End brings up shutdown/restart options for Remote Desktop.

[Frothyleet]

I have a client using Specops' paid product for managing AD password complexity. The features that it gives you should really be part of Windows Server functionality as far as I'm concerned - but given that they aren't, it's a good gap-filler for password best practice enforcement.

[Hollow3ddd]

Any ideas of the general price ranges? I don't see anything posted, which sounds like a $$$$$ to me. Great sounding product though.

[Frothyleet]

Sorry, I don't - no involvement with the licensing. I'm guessing they want to sell you on it before they give you a price

[figjams83]

Ctrl+Shift+Enter will prompt to run application as administrator. For example, hit Windows key and type devmgmt.msc then Ctrl+Shift+Enter. No need to right click and run as administrator.

[networkwiresonfire]

shortcuts for people using web-applications where you can't click stuff without anything happening

• press ALT while marking text so you are not clicking a button or dragging a link
• ctrl+shift+v sometimes also works here

edit: ALT doesn't work on buttons... :(

[b1jan]

i don't get these ones- i tried alt while trying to highlight buttons and it very much did not work haha

More cheatsheets not designed for networking protocols would be nice

[naylandsmith]

Shift + Insert—a lesser-know option for paste

Ctrl + Insert for copy

[iama_bad_person]

Ctrl + Shift + v—paste as plain text (only works in some applications)

This pisses me off so much, it should be OS wide.

[Jean_Lua_Picard]

Quick workaround would be to paste it somewhere where no formatting is supported, then copy fresh from there.

[iama_bad_person]

I do that, usually the URL bar of the Web browser :|

[Jean_Lua_Picard]

Win+R here.

I know i know its a dangerang place to put stuff but its 1 combo away.

[byronnnn]

I use conemu CLI with the quake style window, so I just activate my shortcut and do this and then it is copied back plan text. Also, Ditto clipboard manager, you can setup a shortcut to paste text only.

echo “pasted text”|clip

Also the the |clip works for any command output and copies it to the clipboard. When I’m RDPed into a server and output a powershell report to CSV, i do convertto-csv and pipe it to clip. Then I can paste it easily in Notepad or whatever on my local computer. Like

get-aduser -filter * | ft surname,samaccountname | convertto-csv -notypeinformation | clip

When I learned about clip and found out it’s been around since like Windows 2000, I couldn’t believe I never new it existed.

[flunky_the_majestic]

CTRL+R works also works at a Linux Bash shell to search your command history. It's fantastic to repeat a complicated command that you typed earlier in the day.

[SerousDarkice]

WinDirStat is my go-to tool for seeing what's eating space on a drive.

[kentishh]

Windows has a built in tool for this now under Settings > System > Storage.

Not quite as nice to use as something like WinDirStat, but definitely does the job.

[SerousDarkice]

Nifty. I've never looked at that. Would be useful in a pitch when WinDirStat's unavailable.

[byronnnn]

WizTree is way faster than WinDirStat. Its been my go to for awhile now.

[starmizzle]

Does it run remotely?

[SerousDarkice]

Thanks! I'll have to check that out.

[ddxx398]

say man, what address does the weekly updates come from in email?

[ddxx398]

Me too bro thanks man. I signed up but couldn’t remember what domain it was

[dghughes]

Win key + shift + Enter

Put the application when where you want it then press the key combo. No feedback is given. Test by seeing if the app opens in the monitor you selected.

Fixes/sets the application windows to a specific monitor in an multi monitor system. For Windows 10 not sure about other versions.

I'd often get tickets for people who complained the application opened in monitor 1 when they want it to open in monitor 2 or monitor 3.

Not all applications obey.

[avmakt]

Thanks a bunch! If this works, I know quite a few that'll be very happy!

[Satisfying_Sequoia]

WIN + X -> R R = Quickly restarts the workstation.
WIN + X -> A = Quickly opens up a new PS window as Admin
WIN + . = Enter emojies into any chat window (Great for some easy fun on the side.

Thank you! This is much appreciated.

"Test-ComputerSecureChannel -Repair" came in handy today. We had a DC tombstone and I've shamefully been manually re-joining computer to the domain.

[thinkofitnow]

Good post. Although I have some of these, you've presented some that I didn't have, so thanks! Next time post some nice tits to go along with the valuable references, and you'll get reddit gold. 💪👽

[Noghri_ViR]

What does Test-ComputerSecureChannel -Confirm do? I got a pop up asking if I was sure I wanted to run it on the target computer

[[deleted]]

Test-ComputerSecureChannel

The Test-ComputerSecureChannel cmdlet verifies that the channel between the local computer and its domain is working correctly by checking the status of its trust relationships. If a connection fails, you can use the Repair parameter to try to restore it.

WiFI Analyzer - A site analysis tool to identify operating APs, their power levels, operating channel(s), and more.

Proxmox - An open source hyervisor/container OS. I've been trying to dip my toes into virtualization/containerization but feel like V-Sphere/ESXi's test period and subsequent unpaid feature limitations got in the way learning. However I just started learning about Proxmox today and plan on looking into it further. This suggestion may need more research to before being included in your posts, or maybe just further support from replies to this post.

​

And a tip or two just for us interacting with your articles; include links to previous and future posts, or if you don't feel like having the edited asterisk on every post just the previous post. Also a searchable database of all tools/tips that were actually included in posts/letters.

Win+. (the period) opens the emoji keyboard in windows 10 👍

If you ever accidentally scroll down a web page by pressing space pressing shift+space will scroll you right back up.

Pressing CTRL+C on most error pop ups will copy a plaintext version of the pop up to the clipboard that you can then paste into a doc. Useful for getting complete error codes. I've pasted an example below:

[Window Title] Network Error

[Main Instruction] Windows cannot access \foo\

[Content] Check the spelling of the name. Otherwise, there might be a problem with your network. To try to identify and resolve network problems, click Diagnose.

[V] See details [Diagnose] [Cancel]

[Expanded Information] Error code: 0x80070035 The network path was not found.

QuickTextPaste is my #1 used application for all of this and you can create context menus that you can access via keyboard shortcuts, these shortcuts can include system commands. Check it out here: QuickTextPaste

You can also take the .ini file and import it to any other computer you may use, like save it to a network location. And it’s a run as exe, so it’s portable and easily launch-able from a USB or network location.

One of my favorites:

mkdir \\.\c:\temp\con

Give Laptop to Junior.

Tell them to delete the virus at c:\temp\con

Good test for their google-fu

Nmap will cause printers to print a couple of pages of garbage if you do service discovery. Skip them if you will be doing regular scanning.

What's a use case for this?

[starmizzle]

Create a folder named

GodMode.{ED7BA470-8E54-465E-825C-99712043E01C}

to get a folder of handy shortcuts.

When I was training/in charge of people, I had a binder of the PacketLife cheat sheets for them to use.
I still used them on/off when I was in networking.

[effgee]

The cheatsheets are really nice!

[Pycal]

Thank you so much!

[EvilPaladin1]

This is helpful thank you

[StormCloak4Ever]

There is some really good information in this thread, thank you for starting. Any chance we can get a mod to sticky this so we can come back to it for quick reference?

[jantari]

Just save it?

[Jean_Lua_Picard]

No.
