After a few years on hold it’s great to be back at CITC this time in the British Motor Museum. The video presentation covers a short (if speedy) introduction to Node-RED and it’s ability to integrate systems through their APIs. Demo 2 is of note and shows how a user visiting a malicious website can have their internet access revoked… Read more
Category: The Cloud
The idea of ‘cloud’ computing has been around since the first web based email services but only in the past few years has the term become mainstream.
Here I look into software that runs somewhere other than on your PC.
Palo Alto Networks GlobalProtect and Azure AD – AADSTS700016: Application with identifier was not found in the directory.
When setting up a GlobalProtect Portal/Gateway with AzureAD you may find you receive the error message: AADSTS700016: Application with identifier <Entity ID> was not found in the directory ‘<Directory ID>’. The fix here is easy – the GlobalProtect client injects a :443 at the end of the domain name which isn’t mentioned in the guide from Microsoft (https://docs.microsoft.com/en-us/azure/active-directory/saas-apps/palo-alto-networks-globalprotect-tutorial) but is… Read more
Interacting with the Ruckus Cloudpath API using PowerShell
It’s been a while since posting and I do hope to sort that out but for now another quick mention of some work with Ruckus Cloudpath. Although massively flexible in its design I’ve come into a few niche cases where administrators would like a single DPSK pool (which is bound to a single SSID) but where different users have different… Read more
Processing Cortex XDR Syslog/CEF with Graylog
It’s a bit of an odd situation but sometimes you might want to take information from a cloud service in this case Cortex XDR from Palo Alto Networks and drag it into an on premise logging service. This guide will have a look at how to get this log data in as well as parse it such that you can… Read more
Intune Certificate Connector and 0x80094800
In configuring the Microsoft Intune Certificate Connector and attempting to issue certificates to your client via Intune you might run into the error message below. IssuePfx – COMException: System.Runtime.InteropServices.COMException (0x80094800): The requested certificate template is not supported by this CA.

CITC 19 The tiny development board for all your IoT needs!
It’s always a pleasure to run a presentation and at this years Oxford and Cambridge Colleges IT Conference has definitely been one of the highlights covering a new hobby – running all kinds of IoT applications on the ESP8266 micro-controller.
RDS on Server 2016, Failed: Unable to install the role services.
In putting together a small RDS (Session Based) environment on Server 2016 today today I kept running across the error message below during the installation. Failed: Unable to install the role services. After much back and forth between forums and event viewer it turns out our default policy to disable TLS 1.0 on servers was the issue. Enabling TLS 1.0… Read more

Your account has been flagged. Because of that, your profile is hidden from the public. If you believe this is a mistake, contact support to have… Read more
PowerShell script to download an RSS feed and alert when there are new posts
One of my favourite features of PowerShell is the Invoke-RestMethod cmdlet which (among a great many other things) can download the data from an RSS feed. One application I’ve found for this is to stay on top of security bulletins from organisations like Adobe and Drupal. However just downloading the data from the feed and kicking it out in an… Read more
Synology DiskStation as a Backup Target for Windows PCs and Macs
As some readers may know I currently work in Higher Education and while all of the business data is trivial to backup providing any level of backup service to students and academics is significantly harder. The challenges faced include the myriad of Operating Systems in use (Windows/OSX/Linux), the fact that the devices being backed up are inherently ‘untrusted’ (i.e. owned by the… Read more
