Lync 2010 client version summary

Posted by on

I’ve long stopped blogging Lync 2010 client versions, but I recently had cause to go for a bit of a search, and there were some I encountered in the wild that I’d not previously documented here.

Here are a few more versions and some links. This isn’t a comprehensive list, but is intended to augment those that will be revealed if you use the Search function on the blog.

Some of the below was sourced from Andrew’s blog, and others from Frank Carius.

As best I can tell, 4.0.7577.4540 from Sept 2017 remains the last update to this long-obsolete client.

Raspberry Pi shutdown button

Posted by on

We have a small but growing collection of Raspberry Pi devices here. They’re performing a range of tasks: one’s our Pi-Hole, another runs the “Homebridge” middleware between Apple’s HomeKit and our Clipsal C-Bus, whilst a third is running the management app for Ubiquiti UniFi. And of course plenty more are strewn around the place running various test builds of the intvlm8r.

All of these are running headless, so it means if we want to shut them down for any reason we first need to SSH into them to initiate a ‘sudo shutdown now’.

There are some ‘shims’ on the market that provide on/off switch functionality and even potentially some power management, but they’re relatively expensive and generally overkill for our purposes.

A well kept secret is that the Raspberry Pi has for a while now had the ability to initiate a shutdown from an IO pin, and even to start it up again at the OS level – no scripts or fancy hardware required!

All you need is a momentary switch and one line of code in config.txt.

Begin-Process-End in a PowerShell script

Posted by on

Much has been written about how you need to use Begin/Process/End blocks in order to handle a collection of values passed from the pipeline, but those posts all seem to focus on how to do it in a *function*, not a script.

I recently struggled to figure out how to retrofit this functionality into one of my existing PowerShell scripts.

If you’re here I guess you already know WHY you want to do it, but it’s the HOW what’s causing you distress.

Seen this and had your script dump a list of running processes to screen?

begin : The term 'begin' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling
of the name, or if a path was included, verify that the path is correct and try again.

The trick is simple: there can be NO executable code outside the B/P/E blocks. Nothing. No ‘statics’, no hash tables declared, no functions, not a sausage. Once you move the lot into the Begin block, it’s plain sailing.

Adventures with Import- and Update-CsUserData Pt.4

Posted by on

I’ve spent a lot of time in the past 12 months working with the <verb>-CsUserData commandlets in SfB, and it’s been an interesting time.

This is part 4 in a series where I document the traps I’ve fallen into with the Import-CsUserData and Update-CsUserData commands in particular.

Part 1 – Update-CsUserData fails on bad data.
Part 2 – Your Front-End won’t start after Import-CsUserData imports bad data.
Part 3 – Update-CsUserData throws false red and runs slow if your paired pool is offline.
Part 4 – You can’t trust Import-CsUserData to tell you if it fails.

Part 4 – You can’t trust Import-CsUserData to tell you if it fails

Having abandoned Update-CsUserData we moved to Import-CsUserData, but that wasn’t the bed of roses we were expecting either.

TL;DR: DON’T run “Import-CsUserData” without the -Verbose switch, and make sure you pay attention to its output. If it has some objection to your XML or ZIP file it might silently fail. Only with the -Verbose switch will you know for sure*.

(*) And even then I wouldn’t bank my career on it.

Adventures with Import- and Update-CsUserData Pt.3

I’ve spent a lot of time in the past 12 months working with the <verb>-CsUserData commandlets in SfB, and it’s been an interesting time.

This is part 3 in a series where I document the traps I’ve fallen into with the Import-CsUserData and Update-CsUserData commands in particular.

Part 1 – Update-CsUserData fails on bad data.
Part 2 – Your Front-End won’t start after Import-CsUserData imports bad data.
Part 3 – Update-CsUserData throws false red and runs slow if your paired pool is offline
Part 4 – You can’t trust Import-CsUserData to tell you if it fails.

Part 3 – Update-CsUserData throws false red and runs slow if your paired pool is offline

TL;DR: If you have paired pools, Update-CsUserData will throw red – appearing to fail – and potentially take a LONG time to execute if your paired pool is offline / failed over. Even if it’s still responding, if that other PoolState is FailedOver, you’re in dangerous territory.

SfBS RGS lets you spoof a SIP Domain

Posted by on


 
A long-standing bug in Skype for Business’s Response Group Service (“RGS”) is that it doesn’t validate the line URI when you create a new Workflow. This means it won’t err out if you chose a number that’s already in use elsewhere, and the upshot is that neither the existing user nor the response group can be called. Tracing will reveal a “SIP/2.0 485 Ambiguous” error.

But did you know it doesn’t validate the SIP Domain either?

You can create a Workflow for ANY SIP domain, and not only will it save it without error – it will route!

Get-WeatherLinkData.ps1

Posted by on

We’ve had a Davis Instruments Vantage Vue weather station on the roof for some time now, and with the addition of the “WeatherLinkIP datalogger” its data is uploaded to the greater Davis WeatherLink platform automatically.

Their service is subscription-based, and we’ve not seen sufficient value in giving them ~AUD5/month to have access to the historical data, so we’re stuck on the quasi “real-time only” free tier.

We happen to use the free version of Paessler’s PRTG Network Monitor to monitor all we have here, and it recently occurred to Rocky to see if we could capture the weather station’s data as well. Turns out that’s a YES.

2020 mugshot: an ivory 400-series handset

Posted by on

The phone in my ‘mugshot’ this year is, like me, quite a relic. It’s an ivory-coloured handset from a 400-series phone.

At the start of last century telephones were typically constructed of timber or metal. It wasn’t until the late 1920’s that the British Siemens company developed the first plastic phone, made of a “thermo setting phenolic material”.

Lync 2013 / SfB 2015 Client Security Update – July 2019

Posted by on

Here we are boldly staring down Christmas again for another year, and I’ve just realised not one but TWO updates to the Office 2013-based Skype for Business client have snuck past me in recent months. (Well, at least I have a handy New Year’s Resolution up my sleeve now…)

The previous update was June, and this security update (Kb 4475519) took us from 15.0.5145.1000 to 15.0.5153.1001.

What’s Fixed

“This security update resolves an information disclosure vulnerability that exists if Microsoft Exchange allows entities to be created even though they have Display Names that contain non-printable characters. To learn more about the vulnerability, see Microsoft Common Vulnerabilities and Exposures CVE-2019-1084“.
