### Using DinoPass in PowerShell

This is a nice little trick I learnt whilst automating domain user creation with PowerShell, I found generating passwords in PowerShell was always ugly. Just see the example below from a previous post I’d made:

[string]$initialpassword = ([char[]](Get-Random -input$(47..57 + 65..90 +97..122) -count 8)) + (Get-Random -minimum 0 -maximum 10)

$passwordwithspacesremoved =$initialpassword.Replace(' ','')

$convertedpassword = ConvertTo-SecureString -AsPlainText$passwordwithspacesremoved -Force

This would generate a password like “cDUtxlvM5” which is just about as ugly as the code used to create it.

So I decided to use DinoPass instead since it created better looking passwords without the faff of generating them in PowerShell. This is a the code I used:

Invoke-WebRequest -Uri https://www.dinopass.com/password/strong | Select-Object -ExpandProperty content

Which would give me a much nicer, but still secure, password like “poorJump62”. Then to use it when automating domain user creation, I would use the below and put the whole thing into a variable that I would set the password to:

$super_secure_password = Invoke-WebRequest -Uri https://www.dinopass.com/password/strong | Select-Object -ExpandProperty content | ConvertTo-SecureString -AsPlainText -Force Enjoy! ### Blackjack in PowerShell This is a little function that mimics a simplified version of blackjack. I have wrapped it in a function for cleanliness and so that it can be called again. The rules are below: • Get a higher total than the dealer • Keep your total under 21 or you will be bust • That’s it Here is the code for you to try this out yourself, hope you enjoy! function blackjack{ #CHANGING NAME OF WINDOW$pshost = Get-Host
$pswindow =$pshost.UI.RawUI
$pswindow.WindowTitle = "Blackjack" #RESETTING GAME OVER VARIABLE$blackjack_game_over = $false #GENERATING A RANDOM TOTAL FOR THE DEALER$blackjack_dealer_total = Get-Random -Minimum 14 -Maximum 22

#CREATING AN ARRAY FOR THE USERS CARD NUMBERS
$blackjack_user_card_array = [System.Collections.ArrayList]::new("") #GENERATING A RANDOM NUMBER FOR THE USERS FIRST CARD$blackjack_user_first_card = Get-Random -Minimum 1 -Maximum 11

#ADDING USERS FIRST CARD TO ARRAY
$blackjack_user_card_array.Add($blackjack_user_first_card)

#CREATING A VARIABLE TO COUNT USERS TOTAL
$blackjack_user_total =$blackjack_user_first_card

Clear-Host

Write-Host "Your first card is $blackjack_user_first_card" #DO THIS (PLAY GAME) UNTIL THE GAMEOVER VARIABLE IS TRUE do { #GET USER INPUT do {$blackjack_input = Read-Host "Take another card?

#ADD NEW CARD TO CARD ARRAY
$blackjack_user_card_array.Add($blackjack_user_new_card)

}

### Enumerating PowerShell Options

This is quite a handy trick that I use when designing or just fiddling around with what I can do with PowerShell WinForms. The last time I used this was to get all the possible colours I could use for my form background, and also check the possible options for my border on a panel.

So if I wanted to find all the possible colours available for my forms background, I would use the following:

[enum]::GetValues([System.ConsoleColor])

Black
DarkBlue
DarkGreen
DarkCyan
DarkRed
DarkMagenta
DarkYellow
Gray
DarkGray
Blue
Green
Cyan
Red
Magenta
Yellow
White

or if I wanted to find out all the possible borders for my panel as I stated above, I would use the following:

[enum]::GetValues([System.Windows.Forms.BorderStyle])

None
FixedSingle
Fixed3D

Hope this helps, I know this is usually helpful for me. Enjoy!

### Swaks Email Scripting

Hi, in this blog post I will show you how I configured Swaks for sending emails using SMTP using my custom SMTP server.

First I ran the following command to install swaks:

sudo apt-get install swaks

With swaks installed, I could start building a test command just to
see if this would actually work. I started with the below command:

swaks --to destination@email.com --from source@email.com --auth --auth-user=source@email.com --auth-password=passwordforsource@email.comaccount --server smtp.example.com -tls

This gave me an error along the lines of “Could not authenticate – connection refused” after talking to the people hosting my SMTP server, I found out that I needed to make sure that I was using port 587 and not the default port of 465.

So I made sure that my command explicitly used that port by adding it to the server parameter and managed to get an email to successfully send. You can see the code I used below:

swaks --to destination@email.com --from source@email.com --auth --auth-user=source@email.com --auth-password=passwordforsource@email.comaccount --server smtp.example.com:587 -tls

## Extra

I wanted to use this in a script so that I could launch the script and an email would get sent. I also wanted to change what would get sent in the actual email since currently, it was just using the default values.

After 5 or so minutes of cobbling a script together, I came up with what you can see below:

#!/bin/bash

hostname=$(hostname) uptime=$(uptime)

swaks --to destination@email.com \
--from=source@email.com \
--auth \
--auth-user=source@email.com \
--auth-password=password-for-source-email \
--server smtp.example.com:587 \
--body "$hostname - uptime is$uptime" \
--header "Subject: $hostname is still up" \ -tls \ Now I can send this email whenever I want, I even created a CRON job to send the email every hour. Enjoy! ### Make Website Confirm Before Leaving Long pause between blogs here but busy life = slow blog. In this blog, I will discuss how I created a simple webpage that would allow me to leave a pinned tab open in my web browser that would create a popup box when trying to leave the site. The popup box can be seen below: This is helpful because Chrome doesn’t give the option to make sure you actually want to close the window. So if you have ever, just like myself, been 2 hours deep into researching something that seemed really important at the time and then accidentally clicked the red X and have it all close, then you know how I feel. So I created my own website that I would load and pin in the Chome windows so that this wouldn’t happen to me. This is the code that I used: <script> window.onbeforeload = function(){ return "Do you really want to leave?"; }; </script> and the site that I created is currently live at noautoclose.mharwood.uk Just make sure to click anywhere on the page for the script to work, enjoy! ### LAPS Winform *UPDATE* I have created the *final* iteration of this WPF form which can be found here *UPDATE* I didn’t like having to remote desktop into my domain controller and couldn’t figure out if there was a LAPS tool included in RSAT tools so I decided just to make my own and to add some extra features. I wanted the GUI to look pretty much identity to the actual LAPS GUI. You can see the difference below: You might be able to see that I changed the “Set” button to say “Set and Update”. This was because I wanted the form to also attempt to update the group policy settings on the computer so that it would get a new password a lot quicker than the original GUI. There’s not much else I can say, I will leave the entire script below for you to copy and paste. You will need to add the domain controller for your environment in the$domaincontroller variable at the top of the script. I have converted this to an EXE and run whenever I need it, never skips a beat. Let me know how you get on with it. Enjoy!

### Bold Text:

#Starts bold characters

$(tput bold)TEXT HERE #Ends bold characters$(tput sgr0)TEXT HERE

I would just like to add here that tput sgr0 removes all formatting and returns text to the default style and colour.

### Underlining:

#Starts underlining

$(tput smul)TEXT HERE #Ends underlining$(tput rmul)TEXT HERE

Below is a full script which includes all the possible combinations of the examples above, apart from black text.

#!/bin/bash

echo "
regular bold underline
$(tput setaf 1)Text$(tput bold)Text $(tput sgr0)$(tput setaf 1)$(tput smul)Text$(tput rmul)
$(tput setaf 2)Text$(tput bold)Text $(tput sgr0)$(tput setaf 2)$(tput smul)Text$(tput rmul)
$(tput setaf 3)Text$(tput bold)Text $(tput sgr0)$(tput setaf 3)$(tput smul)Text$(tput rmul)
$(tput setaf 4)Text$(tput bold)Text $(tput sgr0)$(tput setaf 4)$(tput smul)Text$(tput rmul)
$(tput setaf 5)Text$(tput bold)Text $(tput sgr0)$(tput setaf 5)$(tput smul)Text$(tput rmul)
$(tput setaf 6)Text$(tput bold)Text $(tput sgr0)$(tput setaf 6)$(tput smul)Text$(tput rmul)
$(tput setaf 7)Text$(tput bold)Text $(tput sgr0)$(tput setaf 7)$(tput smul)Text$(tput rmul)

I know it looks quite horrible in the source code but this is what the output looks like:

Enjoy!

### Server Reboot Script

Running a little low on content this last few months, plus I’ve been busy with other work stuff.

I had the requirement to create a PowerShell script that would get the uptime of a server and then decide whether or not the server needed rebooting.

I also wanted the script to randomize the reboot of the servers, that way if there are multiple servers that need rebooting at once, they don’t cause a power spike or resource issues on the hosts. I did this by creating a random number between 1 and 5 and then if the number equals 5, the server is rebooted. If not then the server isn’t rebooted.

This is the script that I ended up with and what is currently being tested:

$loglocation = "C:\scripts\reboot\log"$dateforfile = Get-Date

#GETS UPTIME IN DAYS
$lastbootuptime = Get-WmiObject win32_operatingsystem$uptime = (Get-Date) - ($lastbootuptime.converttodatetime($lastbootuptime.lastbootuptime))
$uptimeindays =$uptime.days

#GETS RANDOM NUMBER
$randomnumber = Get-Random -Minimum 1 -Maximum 6 if ($uptimeindays -ge "14"){

Add-Content -Path "$loglocation\$env:COMPUTERNAME.txt" -Value @"
=====================================================================================
Server restarted at:
$dateforfile This was an immediate shutdown as the server had been up for$uptimeindays days
"@

Restart-Computer -Force

}elseif ($uptimeindays -lt "14" -and$uptimeindays -ge "7"){

if ($randomnumber -eq "5"){ Add-Content -Path "$loglocation\$env:COMPUTERNAME.txt" -Value @" ===================================================================================== Server restarted at :$dateforfile
This was a random restart as uptime was only $uptimeindays days "@ Restart-Computer -Force }else{ Add-Content -Path "$loglocation\$env:COMPUTERNAME.txt" -Value @" ===================================================================================== Server NOT restarted$dateforfile
This was not randomly restarted. Uptime is currently $uptimeindays days. Random number was$randomnumber
"@
}
}else{

Add-Content -Path "loglocation\$env:COMPUTERNAME.txt" -Value @" ===================================================================================== No restart required$dateforfile
No restart required since uptime is only $uptimeindays days "@ } The first time I created this script and set it up as a scheduled task, nothing happened. Turns out that I needed the -Force parameter in order for the server to be rebooted. This will later be used in a group policy without the log creating as that is only necessary in the testing stage. Enjoy! ### Creating a Logon Script To Cleanup User Directories In this post, I’ll discuss how I created a PowerShell script that runs when a user logs out of a terminal server and cleans up a directory in their home folder that was filling up with space due to application crashes. This is the script I created: $username = $ENV:USERPROFILENAME$testpath = Test-Path -Path "$username\AppData\Local\Microsoft\Windows\ApplicationFolder" if ($testpath -eq $true){$items = Get-ChildItem - Path "$username\AppData\Local\Microsoft\Windows\ApplicationFolder" foreach($i in $items){ Remove-Item -Path "$username\AppData\Local\Microsoft\Windows\ApplicationFolder\$i" -Recurse -Confirm:$FALSE

}

}else{}

This code will get the users profile root path and then check if the application folder exists, if it doesn’t then the script ends. If it does exist, the script will cycle through each entry and remove it.

The -Confirm:\$FALSE parameter was added because the script kept asking for confirmation when deleting each item. This stops this behaviors and deletes each item without a confirmation prompt.

Now that I have the script and it is working as expected, I create a local group policy that will use:

Name – “powershell.exe”

Parameters – “-F “C:\path\to\file.ps1”

You can see this in the screenshot below:

This group policy was added under:

User Configuration – Windows Settings – Scripts (Logon/Logoff) – Logoff

Hopefully you can replicate what I have done and don’t experience any issue. Note that you might need to change the script execution policy on the machine before this works properly. Just something to keep in mind if the group policy isn’t working. Enjoy!
