One downside of moving jobs is that I’ve had to give back all of the kit I was using that belongs to Fujitsu*. The car went back last month at the end of its lease but yesterday I returned a pile of technology to the office including mobile phone, laptop, monitor, printer.

Hang on. Printer. I’m not the only user of that particular device…

I never liked it anyway – I’ve had a succession of OfficeJet all-in-one devices since I swapped out my trusty old LaserJet for a company-supplied printer and I’ve found inkjet devices to be expensive in consumables (non-OEM cartridges gunking up; OEM cartridges running out even when they say they have ink in them) and the HP OfficeJet 4620 that I’ve used for the last couple of years was particularly unreliable from a software perspective too. So I decided to pick up a small-office laser printer instead and the Samsung SL-C410W was just £130 for a colour laser printer.

Of course some will say, if I think ink cartridges are expensive, wait until I have to buy toner and the other items that the new printer will need but we’re talking in thousands of pages here… for someone who gets through about a box of paper (2500 sheets) every 2 years or so (and half of that has been taken by the kids for drawing)!

Anyway, back to the point. The SL-C410W was available at a great price direct from Samsung (£20 cheaper than John Lewis or PC World – and Staples were way off the mark), with free next-day delivery. Setup was simple, following the supplied instructions to get connected to my Wi-Fi network (although I did install the software on a PC and use the supplied USB cable to make things easy).  There were a couple of points that it might have been useful to know though:

  • Setting a static IP address needed a connection to the printer’s SyncThru web service – either using the supplied software to find the device on the network or using the DHCP logs to work out which IP address it was using and going to http://ipaddress/sws/index.html.
  • Once in SyncThru, login is required to make changes – default username is admin and password is sec00000.

With the password and IP address changed and discovery services configured, our family PC (running Windows 8.1) automatically found and connected to the printer, whilst the Windows 7 PCs only needed me to walk through a wizard (printer and driver location was automatic).

That just left the issue of copying – a feature on the OfficeJet that we do use sometimes. Here, some open source software called iCopy came to the rescue.  It does exactly what it says on the tin – provides a “free photocopier” by linking a scanner and a printer – nothing that can’t be done manually but a single button was helpful for family members who use this feature.

The only slight problem was locating Windows Image Aquisition (WIA) drivers for my elderly CanoScan N650U/N656U with Canon not offering anything for Windows 7 and the Internet seemingly littered with dead links.  Luckily, Tom Heath has posted a link to the drivers and these worked a treat.

Only time will tell whether the SL-C410W was a wise buy or not – but at least my family have a means to print homework, my wife has a printer (and copier) again for her work, and I have something that should be reasonably reliable and hassle-free…

 

* There are lots of upsides too – including that my new “laptop” will be a Surface Pro 3, and that I’ll be using modern software to help me in my work.

Moving on…

Just under ten years ago, I wrote a blog post to say I was leaving Conchango, and (re-)joining Fujitsu (it was ICL when I left).  Since then, I’ve moved through a succession of roles (technical, IT strategy and governance, management and pre-sales), worked with some extremely talented people and I’ve had some good times (as well as some less good) but one of the highlights has to be when I was given a Fujitsu Distinguished Engineer award last year.

Receiving a Fujitsu Distinguished Engineer award from Michael Keegan (Head of UK and Ireland region) and Jon Wrennall (CTO), in October 2014

Now, that time has come to an end, because today’s my last day at Fujitsu before I take up a new role in just over a week’s time.

For those who didn’t see my tweet last month, I’ll be returning to technical consultancy, joining the unified communications team at risual.

risual is a dedicated, UK based, globally recognised IT Services organisation delivering business aligned consultancy, solutions and services based solely on the Microsoft platform.  Along with several thousand others, I first came across risual when their corporate video was launched at Microsoft Future Decoded last year and what a refreshing change it made! Digging a little deeper told me they have a great reputation – and that’s capped off by appearing in The Sunday Times’ top 100 best small companies to work for list.

I have to admit I am a little anxious about the move – but really excited too and looking forward to joining the risual “family” and getting stuck in.  And, if ever there was proof of what a small industry we work in, I already found that I’m linked to quite a few of my new colleagues through Twitter or this blog!

Public key infrastructure explained

Posted on By Mark Wilson
This content is 10 years old. I don't routinely update old blog posts as they are only intended to represent a view at a particular point in time. Please be warned that the information here may be out of date.

Last week, I was attending a presentation skills course where we had to give an impromptu presentation (well, we had an hour to prepare) on a topic of our choice.  One of my colleagues, Richard Butler, gave his talk on public key infrastructure (PKI) and Richard was the first person who has explained PKI to me in a way that made me go “ah! got it!” because he used a great analogy.

So, I’m going to attempt to repeat it here (with Richard’s permission)… and hopefully I’ll get it right!

Richard’s first point was that PKI is thought of as a security tool, some technology, or something that’s needed to make the network secure. Actually, he suggests, there’s more to it than that…

The first example Richard gives is one of a server certificate (used to ensure that a service can be trusted and that confidentiality is maintained), illustrated by way of border control.

An airline passenger approaches a border (e.g. an immigration desk at the airport):

  1. The border is where the passenger expects it to be.
  2. A border guard wears a uniform, with an insignia (badge).
  3. The passenger recognises the insignia and trusts it as genuine.
  4. The passenger interacts with the border guard to negotiate entry to the country.

A server certificate is similar because it’s presented to prove that the server is who they say they are and is trusted by users accessing its services. The certificate is issued by a certificate authority, just as the border guard’s badge is issued by a government agency.

In Richard’s second example, a certificate is used to provide confidence that you are who you say you are, a process known as integrity or repudiation.

  1. As a citizen of a country, I request a passport from my government.
  2. The government validates my request.
  3. If my request is valid, a passport is issued.
  4. When visiting a foreign country, I present my passport at the border.
  5. The government of the foreign country trusts the government that issued the password to have carried out the necessary background checks that confirm I am who I say I am.
  6. I’m authorised to enter the country.

In this case:

  • The issuing government’s passport authority can be thought of as a certificate authority (CA) or issuing authority (IA) – it’s trusted by other countries to authorise passports.
  • The passport can be thought of as a validated “client” certificate – it is trusted, because the passport authority is trusted (i.e. there is a chain of trust).
  • The government in the foreign country can also be thought of as a certificate authority – it is trusted and authorises the immigration control.
  • As described in the first example, the border guard’s insignia can be thought of as a “server” certificate – it is trusted as the foreign country is trusted to issue certificates.
  • Humans apply logic to the approach and automatically make the appropriate assumptions and associations.

In a public key infrastructure, there’s a hierarchy of certificate authorities:

  • The offline root CA signs requests for sub-ordinate servers and holds the private key for the certificate root.
  • A networked, subordinate CA signs requests for clients, and holds its own private key.
  • A certificate distribution point stores the public keys for the root CA and the subordinate CA (used to validate requests). It also holds information about certificate revocation (to use the passport analogy, this might be where a citizen has been denied the right to travel, for example due to a pending prosecution).

Using this PKI infrastructure a number of interactions take place:

  1. A device creates a signing request and sends it to a certificate authority.
  2. The CA receives the signing request, validates the request, and issues a certificate signed with its private key.
  3. The original device receives the signed certificate and stores it for future use as a client/server certificate.
  4. When a connection to a service is attempted, the connecting device receives a copy of the certificate and validates the name and signing CA using their public key. This validates the certificate chain and the certificate is proved to be valid.

At the outset of this description, Richard explained that there is more to PKI than just a security tool, or some technology services.  There’s actually a hierarchy of deployment considerations:

  • Private key protection. Private keys are critical to the ability to sign certificates and therefore crucial to the integrity of the chain of trust.
    • A chain is only as strong as its weakest link.
  • Management procedures:
    • Validation of requests (stopping fraudulent certificates from being issued).
    • Management of certificates (issuing, revocation, etc.)
  • Deployment procedures:
    • Deploying and managing the PKI infrastructure itself.
  • Technology choices:
    • Whose PKI infrastructure will be used?

Drawn as a hierarchy (similar to Maslow’s hierarchy of needs), technology choices are at the top and are actually the least significant consideration.  Whilst having a secure technical solution is important, having the procedures to manage it are more so.

Richard wrapped up his presentation surmising that:

  • PKI is 10% technology and 90% process.
  • Deployment is 10% of the solution and management is 90%.
  • PKI needs management from day one.

If you do still want to know more about the technology (including seeing some diagrams that might have helped to illustrate this post if I’d had the time), there’s a Microsoft blog post series on designing and implementing PKI, written by the Active Directory Directory Services team.  Other PKI solutions exist, but as many organisations have an Active Directory, looking at the Microsoft implementation is as good a place as any to start to understand the various technologies that are involved.

Short takes: Lync/Skype and browsers; Bitlocker without TPM; OS X Finder preferences; and MyFitnessPal streaks

A few more short mini-posts from the items that have been cluttering my browser tabs this week…

Lync/Skype for Business meetings start in the Web App

A few days ago, a colleague highlighted to me that, whenever she joined a Lync meeting from our company, it opened in Lync Web App, rather than using the full client. Yesterday I noticed the same – I tried to join a call hosted by Microsoft and the Skype for Business Web App launched, rather that the Lync client installed on my PC. It turns out that this behaviour is driven by the default browser: mine is Chrome and my colleague was also using something that’s not IE. Quite why I’d not seen this before, I don’t know (unless it’s related to a recent update) but for internal Lync meetings I do tend to use the Join Online button in the meeting reminder – that doesn’t seem to appear for external meetings. Of course, you can also control which client is used by editing the URL…

Using Bitlocker on drives without TPM

When my wife asked me to encrypt the hard drive on her PC, I was pleased to be able to say “no need to buy anything, we can use Bitlocker – it’s built into Windows”. Unfortunately, when I tried to enable it, I found that her PC doesn’t have a trusted platform module (TPM) chip. I was pretty sure I’d worked around that in the past, with a netbook that I used to run Windows 7 on and, sure enough, found a How To Geek article on How To Use BitLocker on Drives without TPM. It’s been a while since I had to dive into the Local Computer Policy but a simple tweak to the “Require additional authentication at startup” item under Computer Configuration\Administrative Templates\Windows Components\Bit Locker Drive Encryption\Operating System Drives was all it took to let Windows encrypt the drive.

Finding my files in Finder

One of the challenges I have with the Mac I bought a few months ago, is that modern versions of OS X seem to want to hide things from me. I’m a “browse the hard drive to find my files” kind of guy, and it took a tweak to the Finder preferences to show my Hard Disk and bring back the shortcut to Pictures.

MyFitnessPal streak ends – counter reset

Last weekend some connectivity issues, combined with staying away with friends meant I missed the cut-off for logging my food/exercise with MyFitnessPal and my “streak” was reset (i.e. the login counter). Knowing that I’ve been logging activity for a certain number of days is a surprisingly motivational piece of information but it turns out you can get it reset using the counter reset tool (which even predicted how many days the value should be – 81 in my case).

Office Remote for Windows Phone

Over the next couple of days, I’ll be attending a “presentation masterclass”.  My last formal training in this area was twenty years ago, as a graduate trainee at ICL, so I’m hoping things will have moved on considerably since then in terms of the techniques and advice on offer!

Anyway, attending the course reminded me to blog about something I was introduced to last year by my colleague, Warren Jenkins.  Those of us with Windows or Android phones can use the Office Remote app to control PowerPoint – no need for a “clicker” – just a phone (running Windows Phone 8.x with the Office Remote app – or  Android 4.0.3 or later with the Office Remote for Android app) and a Bluetooth connection to a Windows PC (Windows 7 or 8.x), with the Office Remote PC plug-in for Office 2013.

Once Office Remote PC is installed, and the PC is connected to the phone, open the Office file that you would like to present and, on the Office Remote tab, select Office Remote > Turn On.

Then, go to the phone and make sure it’s running the Office Remote app and, if all is working well, you’ll see a list of open Office files and you can pick the one to present.  For example, in PowerPoint you can see speaker notes and control the presentation, with options to view in slide sorter mode or to use a virtual laser pointer to highlight points on the slide. You can also control other Office applications (e.g. interacting with data and switching between worksheets in Excel, or jumping around between headings or up/down a document in Word), but I’ve only used it in anger with PowerPoint.

More details are available on the online help page.

Adding a pause when dialling a number from a softphone or mobile phone

This content is 10 years old. I don't routinely update old blog posts as they are only intended to represent a view at a particular point in time. Please be warned that the information here may be out of date.

Back in the days when Nokia phones had monochrome screens and batteries lasted for days, a colleague explained to me how to include a p in a number to make the phone pause before dialling the next few digits – for example when entering a PIN for voicemail (I think w also worked for a wait). More recently, another colleague was asking me how to do this with our CUCILync softphones when dialling into a conference call (as described for Microsoft Lync).

Well, it seems the modern equivalent of a p for a soft pause is inserting a comma (at least it is on a Lumia, on an iPhone and on Android) and a semi-colon is a hard pause/wait (on an iPhone). Unfortunately the CUCILync client we use strips out , and ; (and, even worse, it replaces p with 7). I guess it could be an error in the dial-plan but it’s inconvenient…

Amazon AWS Summit highlights (#AWSSummit)

Posted on By Mark Wilson
This content is 10 years old. I don't routinely update old blog posts as they are only intended to represent a view at a particular point in time. Please be warned that the information here may be out of date.

I spent a chunk of time at Amazon’s AWS Summit in London earlier this week. It was interesting to be back at the ExCeL exhibition and convention centre as the last time I was there was another big vendor event – Microsoft Future Decoded – and on the topic of organisation, let’s just say that whilst Amazon had the registration sorted (Microsoft had some issues with that last year), Amazon’s schedule meant we couldn’t get to the technical tracks because of the queues for the escalator (there were no stairs that I could find!).  It seems that ExCeL’s ICC has some logistical challenges when dealing with a few thousand people moving from one level to another!

I was interested to see which partners were exhibiting in the Expo though:

There seem to be plenty of opportunities around cloud services but one set of partners who noticeably absent were the big systems integrators. As we moved to the keynote, I couldn’t tweet the highlights as connectivity became an issue (standard conference issues around WiFi and mobile phone access – plenty of signal but too many sharing it) but I settled into Dr Werner Vogels’ (@Werner) presentation and found it interesting on a number of levels:

  • Whilst there were announcements about Amazon releases, many of the points made were equally applicable to other clouds (e.g. I could apply the same issues and learning to Microsoft Azure):
    • Start-ups have no legacy/dependencies, a low cost structure and can move quickly to disrupt log-standing industries.
    • Not that long ago millions of dollars were required to start an Internet business. It was “indirect funding of the American server industry” – but not any more: cloud infrastructure and platform services have a low barrier to entry and no up-front costs or vendor tie-in.
    • The cloud’s not just for start-ups: enterprises can benefit too (although I’d argue that variable costs are a challenge for some finance departments and new features arriving daily are not always a good thing for end users).
    • Automation is key [in IaaS/PaaS]: whether it’s for testing, building, deployment or infrastructure creation.
    • Real-world workloads come in all shapes and sizes – there’s no need to standardise on the lowest common denominator when you can change the services you use to fit. With cloud you can make mistakes (fail fast and move on) that would be expensive using physical servers or even a virtual infrastructure platform.
    • AWS is a platform and an ecosystem – some organisations are creating their own platforms on top of AWS (e.g. Omnifone’s B2B media platform).
    • Invention is continuous, with new services, and a movement towards micro-services based on smaller blocks (Dr Vogels used a Tetris analogy), containerisation, event-driven computing, etc.
    • Security is a shared responsibility – Amazon provide the tools (and a workbook for compliance with local laws) and customers need to use them correctly.
    • There may be compliance benefits from the cloud, for example: if you store customer data then you become a data controller – and if you process it on AWS, Amazon becomes a data processor; by signing the AWS data processing agreement organisations comply with EU data processing requirements known as article 29, providing assurances that are not available with on-premises services.
  • The stats involved (and Amazon’s growth) are enormous:
    • 102% year on year increase in data in/out of S3.
    • 93% year on year increase in usage of EC2.
    • Over 1 million active customers (every month – excluding amazon.com) – from start-ups to enterprise, in many vertical markets.
    • Five times the compute capacity of the other 14 providers in the Gartner Magic Quadrant for cloud infrastructure as a service combined. 
    • AWS’ pace of innovation is such that 516 major new features and services were launched in 2014 – almost double the previous year (and that’s a pattern with: 24 in 2008; 48 in 2009; 61 in 2010; 82 in 2011; 159 in 2012; 280 in 2013; 516 in 2014) – it’s actually really hard to keep up (and I’d say the same for Azure too!).
  • Whilst Amazon is leading this sector, they did not come across as arrogant – indeed Dr Vogels highlighted that the Amazon motto of being “the earth’s most customer-centric company” applies to AWS too. Customers are in charge, not providers and, if Amazon’s not providing what they need, customers will walk away – perhaps not literally (there’s no lock-in but moving workloads is non-trivial) but they will use another cloud for their next project/programme.

One message that I found difficult to swallow was that “hybrid IT is part of the journey, not the destination“. Maybe that’s true in the long term but, in my world of Microsoft cloud services, I see real use cases for hybrid clouds (I’ll be writing more on that soon).

Maybe it’s because I’m coming from a SaaS angle though, rather than IaaS and PaaS – I did attend a hybrid cloud deep dive session at the AWS Summit but missed the first 10 minutes as I was delayed by the need for micro-escalator-services or the “escalator of things” (credit to Vitor Domingos @VD for that thought).

I can see why, when running your own applications, there is little need for long term usage of on-premises infrastructure or so-called “private cloud” platforms once you’ve taken advantages of the efficiencies that cloud IaaS/PaaS provides. So, creating a hybrid cloud may be a bridge to the future state, rather than a two-way street; but maybe there are limitations about the data that you want to store in the cloud? Perhaps the cloud BC and DR is still too risky (although maybe you could consider multiple clouds)? Or connectivity challenges might exist that rule out exclusive cloud usage? Or perhaps I’m just a Luddite!

One thing’s for sure – applications shouldn’t be moved to the cloud “as is” – cloud migration is an opportunity to rethink how things work – and Amazon has an that might help with that.

Unfortunately, I couldn’t stay for the whole day – there were many more technical tracks I wanted to attend (and huge queues to get into the sessions) but I had an appointment elsewhere. The AWS Summit was certainly a worthwhile investment of my time though (even as a Microsoft consultant) – I’ll be watching out for it again next year.

In conclusion, I’ll make just the one observation: systems integrators need to find new opportunities to deliver value in an increasingly agile and commoditised world – for example as cloud integrators – and they need to move quickly. Incidentally, this is not news – but for a while now we’ve been able to say “cloud is not for everyone”. Increasingly though, those barriers to cloud adoption are being broken down.

Lync becomes Skype for Business today – a quick round-up of what that means

Posted on By Mark Wilson
This content is 10 years old. I don't routinely update old blog posts as they are only intended to represent a view at a particular point in time. Please be warned that the information here may be out of date.

There’s been a fair amount of panic in some quarters as a colleague heard that one of the “patch Tuesday” updates will update our Lync 2013 clients to Skype for Business (which became generally available today). That brings a new user experience and potentially confusion for our users (who are only just getting their heads around switching from OCS and WebEx!). Later on it seemed that the update only applied to Click-to-Run Office ProPlus subscriptions (we have perpetually-licensed MSI-based installations) and finally we got something that I could use to set my colleagues’ minds at rest in a blog post from Scott Stubberfield:

  1. “Patch Tuesday” implies security updates but the Skype for Business update is part of the April monthly update for Office 2013 (i.e. an optional update).
  2. Quoting Scott’s post, “If you are using Lync Online today with Office 365 ProPlus, Office 365 Business Premium or Office 2013, the updated Skype for Business client […] will be the default user experience and replace the Lync user experience.  If you are using Lync Server today, the Lync UI will be the default experience.”. That last sentence is the vital one [although I could have saved a lot of time and effort if I’d seem Martin Boam’s post earlier in the day!].
  3. It is possible to control the user experience (there’s a PowerPoint presentation linked in Scott’s post). We knew that anyway but some of the documentation suggested the registry change needed to be applied in advance of the update. Certainly on my preview client I can switch back and forth at will between the two UIs, using the [HKEY_CURRENT_USER\Software\Microsoft\Office\Lync] key, with a value name EnableSkypeUI, and the data 00 00 00 00. I haven’t got the update yet to test the final release.

Background information

There’s a whole load more information in some really useful posts that Tom Arbuthnot and Matt Landis have put out in the last few days (and an older post from Mark Vale):

More Skype for Business information

On the topic of Skype for Business, Microsoft is running some webinars in a two-part series (aimed at users, not techies). There’s also a stack of help topics available online and the following links might be useful:

Also, although it’s a bit late now for Office 365 users, Microsoft did publish some awareness and readiness planning guidance for the Skype for Business client running with Lync Online (which could be re-purposed for on premises updates).

Louis Lazarus’ Microsoft News Updates

Back in December, I wrote what I intended to be the first of a regular update on what’s going on in the world of Microsoft – a sort of Microsoft news round-up.  Since then, I’ve been alerted to a regular update from Louis Lazarus (an independent technology strategy consultant – @_louislaz) and I’ve been re-posting his updates via Twitter/OneDrive.  The links for recent updates are below (each one covers the previous month):

Directions on Microsoft Enterprise Software Roadmap

As featured in my previous post, Directions on Microsoft is an independent analysis service focused on Microsoft technologies, roadmaps and licensing policies and their latest quarterly roadmap calls attention to recent roadmap shifts for Microsoft enterprise technologies, including:

  • “Windows 10 and Office 2016 for PCs. Previews have appeared for the next versions of Windows and the Office desktop suite, giving organizations an early opportunity to identify potential migration blockers for software currently running on their Windows 7 PCs.
  • Windows Server. The next version of Windows Server has been postponed to 2016, which means Microsoft’s latest PC security and management infrastructure will not be ready when Windows 10 and Office 2016 ship later this year.
  • Mobile e-mail clients. An acquisition has fundamentally changed its mobile e-mail client roadmap for iOS and Android, and could trigger changes to bring-your-own-device (BYOD) policies in organizations.
  • Windows 10 tablets and phones with Office. Windows 10 previews are available for tablets and phones, and Office mobile app previews have appeared for Windows 10. Organizations can use the previews to re-evaluate the future of their Windows mobile device applications.”

[the bullets above are a direct quote from the email I received from Directions on Microsoft]

Tuning iOS 8 location services to improve battery life

Posted on By Mark Wilson
This content is 10 years old. I don't routinely update old blog posts as they are only intended to represent a view at a particular point in time. Please be warned that the information here may be out of date.

I’m not convinced my second hand iPhone 5S is as “grade A” condition as it might have appeared when I bought it recently from SmartfoneStore as, as well as having a dull patch on the top of the screen (that I was ignoring), last night, with 26% battery remaining it suddenly decided to turn off and insisted it needed charging. A few minutes later it could be started again, before once again deciding that 26% battery was not enough! Hey ho, I’ll be contacting them after this holiday weekend for a replacement (and they do offer a 60 day warranty) so it shouldn’t be a problem but it did get me looking at why my iOS 8 battery life is so poor.

The first clue was the GPS icon at the top of the screen. Even with all applications closed, it persisted – so what was using my GPS?  I found the problem app, following a LifeHacker article to see which app had a purple arrow in Location Services but a bit more googling turned up a great article on iGeeksBlog looking at how to fix always-on location services in iOS 8.

You can read the post yourself but, in summary, it goes through switching off system services that might use the GPS like location-based iAds, Spotlight Suggestions, Diagnostics & Usage, and Popular Near Me; as well as controlling which apps can use Location Services (my problem app was Dropbox – I’m not sure why it needs to know where I am but it’s not allowed to any more).

Hopefully now my iOS 8 battery life will improve – although I really must get my phone swapped too…
