At a site, something in the network filtering changed, so printing from a Mac failed.
In the end this was about port 631, which is for the IPP protocol a Mac uses.

Government & Govt Owned – Netherlands – Phishing Scorecard
Posted by jpluimers on 2019/07/12
The archive is of late 2017; I wonder what the state is now: [Wayback] Government & Govt Owned – Netherlands – Phishing Scorecard
This Phishing Scorecard is the current situation of the security of e-mail stream banks compared. If a bank is one of the technical building blocks to implement in their e-mail security the red cross will be a green check mark. Once a bank’s security policy has only green check marks will stand up and protect them 40% of their customers.

PowerShell: get WindowsUpdate information
Posted by jpluimers on 2019/07/11
A while back, I needed to check Windows Update information on a few hosts, so I wanted to script it. Below are a few links that helped me solve this started.
Note: For Windows Update, you need the TiWorker.exe process, which can consume a lot of CPU. See DISM fix for Windows 8.1 high CPU usage of TiWorker.exe which is basically the same for all Windows versions since 8.0.

The infrastructure management on that site was ehm, a bit lacking, so PowerShell modules were out, heck even PowerShell itself was initially problematic (it needed running of unsigned sources.
A few notes on the above links.
Using Microsoft.Update.AutoUpdate
This gets the last date that anything was done (query, actual update, download) on Windows Updates, but does not guarantee the installation date; on some systems it does not even return a result:
$windowsUpdateObject = New-Object -ComObject Microsoft.Update.AutoUpdate
$windowsUpdateObject.Results
This one works better though:
$windowsUpdateObject = New-Object -ComObject Microsoft.Update.AutoUpdate
$windowsUpdateObject.Results.LastInstallationSuccessDate
Based on that, you can get the number of days like this:
(New-TimeSpan -Start $windowsUpdateObject.Results.LastInstallationSuccessDate.Date -End (Get-Date)).Days
Using Get-HotFix
Though some people report that InstalledOn can be empty, I’ve hardly that happen with Get-HotFix. The easiest way to get around that is filtering with | Where-Object InstalledOn -ne $null
The cool thing with Get-HotFix is that you can filter on the kind of security update, so this gets the moment the last security update got installed:
(Get-HotFix -Description "Security Update" | Where-Object InstalledOn -ne $null | Sort-Object InstalledOn -Descending | Select-Object -First 1).InstalledOn
And this the number of days since the last security update got installed:
(New-TimeSpan -Start (Get-HotFix -Description "Security Update" | Where-Object InstalledOn -ne $null | Sort-Object InstalledOn -Descending | Select-Object -First 1).InstalledOn -End (Get-Date)).Days
Step by step:
Get-HotFix -Description "Security Update"Gets all the security updates.
| Where-Object InstalledOn -ne $nullFilter out entries having an empty
InstalledOn.
Sort-Object InstalledOn -DescendingGet the most recent on the top.
| Select-Object -First 1Select only the top entry.
(Get-HotFix -Description "Security Update"...).InstalledOnGet only the
InstalledOnproperty.
Get-DateGet the current timestamp consisting of date and time.
New-TimeSpan -Start (...).InstalledOn -End (Get-Date)Get a
TimeSpanover a start and end timestamp.
(New-TimeSpan ...).DaysGet the
Daysproperty of aTimeSpan.
You can do the same for regular updates by changing the -Description parameter:
(Get-HotFix -Description "Update" | Where-Object InstalledOn -ne $null | Sort-Object InstalledOn -Descending | Select-Object -First 1).InstalledOn
(New-TimeSpan -Start (Get-HotFix -Description "Update" | Where-Object InstalledOn -ne $null | Sort-Object InstalledOn -Descending | Select-Object -First 1).InstalledOn -End (Get-Date)).Days
The Description values I found are these:
PS C:\Users\Developer> Get-HotFix | Sort-Object -Unique Description | Select-Object Description
Description
-----------
Hotfix
Security Update
Update
Ironically, since the command is called Get-HotFix, the Hotfix entries on my various Windows systems have been a long long time ago:
(New-TimeSpan -Start (Get-HotFix -Description "Hotfix" | Where-Object InstalledOn -ne $null | Sort-Object InstalledOn -Descending | Select-Object -First 1).InstalledOn -End (Get-Date)).Days
When writing this in 2017, on Windows 8.1, this was more than 600 days, Windows 7 more than 400 days and Windows 10 did not have any Hotfix entries.
Old PowerShell versions
On PowerShell 2 and older, you get an error containing “Where-Object : Cannot bind parameter ‘FilterScript'”:
Where-Object : Cannot bind parameter 'FilterScript'. Cannot convert the "InstalledOn" value of type "System.String" to type "System.Management.Automation.ScriptBlock".
At line:1 char:48
+ (New-TimeSpan -Start (Get-HotFix | Where-Object <<<< InstalledOn -ne $null | Sort-Object InstalledOn -Descending | Select-Object -First 1).InstalledOn -End (Get-Date)).Days
+ CategoryInfo : InvalidArgument: (:) [Where-Object], ParameterBindingException
+ FullyQualifiedErrorId : CannotConvertArgumentNoMessage,Microsoft.PowerShell.Commands.WhereObjectCommand
You solve it like this:
(New-TimeSpan -Start (Get-HotFix | Where-Object { $_.InstalledOn -ne $null } | Sort-Object InstalledOn -Descending | Select-Object -First 1).InstalledOn -End (Get-Date)).Days
By now code has become almost unreadable, so you can split it using backtick ` characters:
( `
New-TimeSpan -Start `
( `
Get-HotFix | Where-Object { $_.InstalledOn -ne $null } `
| Sort-Object InstalledOn -Descending `
| Select-Object -First 1 `
).InstalledOn `
-End (Get-Date)`
).Days
One more thing
On non-English Windows systems, the InstalledOn might actually be in the future, as you can view this happening by this simple command which I ran on 2017-11-02 :
Get-HotFix | Out-GridView
You solve it by adding a filter:
Get-HotFix | Where-Object InstalledOn -lt (Get-Date) | Out-GridView
If you run them from a script (like a batch file Get-HotFix ^| Out-GridView or ps1 file Get-HotFix | Out-GridView), then the grid-view will pop-up and immediately close because the PowerShell process ends. In that case, you need to change your scripts to add the -Wait parameter:
PowerShell Get-HotFix ^| Out-GridView -Wait
Powershell.exe -Command "Get-HotFix | Out-GridView -Wait"
Get-HotFix | Out-GridView -Wait
See:
- [WayBack] powershell – How to prevent from closing out-gridview when a script finishes – Stack Overflow (thanks Aurimas N)
- [WayBack] Out-GridView examples The Out-GridView cmdlet sends the output from a command to a grid view window where the output is displayed in an interactive table.
In C#
If I ever want to do the same from C#, I need to figure out where to get the WUApiLib from; more on that library is at [WayBack] Use C# to interact with Windows Update – Stack Overflow and [WayBack] Searching, Downloading, and Installing Updates (Windows).

esxi listing usb devices on host console: lsusb

Colored text output in PowerShell console using ANSI / VT100 codes – Stack Overflow

Windows: running a batch file during logon of a single or all users
Posted by jpluimers on 2019/07/01
You can automatically start processes during logon in a lot of ways (Trojans/Viruses find new ways all of the time).
The easiest way is to create a shortcut in one of the Startup folders. There are two of them: one for all the users, and one for the current user. Depending on your locale, Explorer can show a translated name, but the actual folder is named either of these:
"%AllUsersProfile%/Start Menu\Programs\Startup""%AppData%\Microsoft\Windows\Start Menu\Programs\Startup"
The folders do not exist at first, but are created when software starts putting shortcuts in them.
For a manual process, I created the two batch files below that create, then go to them (in both the console and explorer).
From there you can add shortcuts to things you want to run during logon.
They are based on:
- [WayBack] login – Automatically run a script when I log on to Windows – Super User
- [WayBack] batch file – auto run a bat script in windows 7 at login – Stack Overflow
I have successfully tested them in various Windows versions up until 10.
