It’s that magical time of the year where…new network switches arrive! Given that the new Aruba branding has taken full control of what was ProCurve I thought I should post some photos of the new paintwork. Happy to say the colour black isn’t half bad!
Included in the images are
- J9729A 2920-48G-PoE+
- J9728A 2920-48G
- J9731A 2920 2-Port 10Gbe SFP+ Module
- J9733A 2920 2-Port Stacking Module
- J9734A 2920 0.5m Stacking Cable
So this post is a more a reminder to me than anything else but…having recently come across the Microsoft TechNet article ‘Keyboard Shortcuts for the Windows PowerShell ISE’ (https://msdn.microsoft.com/powershell/scripting/core-powershell/ise/keyboard-shortcuts-for-the-windows-powershell-ise) I thought it necessary to highlight the two keyboard shortcuts….
Ctrl + J – brings up a list of code snippet templates (e.g. try-catch-finally and do-until)
Ctrl + M – expand or collapse braces
See the screenshots below for a demo and do make sure you try them yourself!
After recently deploying a Windows Server 2012 R2 WSUS server (afraid we couldn’t wait much longer for 2016 (which is now out by the way!)) we started seeing Error 8024400E on our clients and servers (from 2008R2/Windows 7 to Server 2012 R2/Windows 10).
As it transpires Microsoft published KB3159706 for the WSUS server which adds some new features to be able to manage Windows 10 updates and thus requires some manual post installation steps which can be found at this link here – https://support.microsoft.com/en-gb/kb/3159706.
The steps only took a few minutes to go through so it was a pretty easy fix in the end.
In this guide I’ll show a ‘working’ method to upgrade from MySQL Server 5.1 to 5.5 on a Windows Server 2008 R2 machine. In this case MySQL Server 5.1 was installed by the Microsoft Web Platform Installer some time ago, however this version doesn’t deliver very good performance (and its horribly outdated!) so it was time to get it replaced.
The good chaps at MySQL do offer a guide on how to do this on their website – https://dev.mysql.com/doc/refman/5.5/en/windows-upgrading.html however I hope you will find this one will serve you better.
A few points to note before we continue….
- This guide assumes you are using a default install of MySQL Server 5.1 (as delivered by the Microsoft Web Platform Installer)
- This guide only looks at a ‘simple’ server deployment i.e. no clustering or other funky features are in use
- It is recommended to jump only one version at a time when going from MySQL version to version e.g. 5.1 to 5.5 (there were no 5.2, 5.3 or 5.4 versions) and then 5.5 to 5.6 and 5.6 to 5.7…
- You can download previous versions of MySQL Server from this link – http://dev.mysql.com/downloads/mysql/ just click on the ‘Looking for previous GA versions?’ link
- Be sure to take a backup of your databases before you attempt this guide on a production machine (see https://dev.mysql.com/doc/refman/5.5/en/backup-methods.html for some ideas on how to do this)
- If possible run through the upgrade process a few times on a testing machine (one that you can break and no one will notice) first
So on with the guide!
Final point to note….this guide only works with migrations to 5.5 from 5.1, if going to further versions you will be missing some tables which will in turn generate error messages during the upgrade process. More information on that here http://dba.stackexchange.com/questions/54608/innodb-error-table-mysql-innodb-table-stats-not-found-after-upgrade-to-mys.
Work is coming along nicely with the Server Room, we’ve now removed the last Cisco switch from our infrastructure and the HP 5400R series switch is deployed replacing the 2530 that was in its place; over time we’ll be bringing more fibre from our edge switches into this room as well hence the number of SFP+ ports on the 5400R. The entire front of the cabinet is now populated with hardware or a blanking panel as well (panels available from Comms Express) to keep things looking tidy. I wish there were a little more that I could do with the cables coming into the 5400R however with a very narrow rack there’s not much that can be done.
Some interesting things have come out of both Rucks and PaloAlto recently in that they offer Hyper-V compatible VMs for their services which could free up a further 3U of space and remove a further 4-6 cables out of the picture.
Looking for some fun ways to get more out of your your Smart Card deployment? If so have you tried……?
- Use Smart Cards to login to your Servers via Remote Desktop
- Use Smart Cards with the PowerShell Get-Credential Commandlet
- Use Smart Cards with your Firewall for single sign on
- Use Smart Cards to login to IIS Web Applications (just a box to tick and a radio option to select)
- Store multiple identities on your Smart Card and assign different (and perhaps more complex) PINs to the identities
Have a look at the screen shots below for some more details…
If you are looking for a free tool to manage some of the more intricate features of the Gemalto IDPrime .NET and MD cards then the Mini-Driver Manager (downloadable from http://www.gemalto.com/products/dotnet_card/resources/development.html) may well fit the bill. However it has one small downfall in that out of the box it only allows you to manage cards with the Admin Key set to 48 0s or 48 Fs with neither option being much use to anyone once they have changed the Admin PIN.
Luckily these values are only set in a INI file so its pretty easy to change them to anything else.
Please note that this guide uses a feature in Notepad++ to elevate an application to have local Admin access, you can download Notepad++ from https://notepad-plus-plus.org however you could also use plain old Notepad you’ll just need to launch it as an Administrator and browse to the INI file within Notepad.
On with the guide!!
So after meaning to play with Smart Cards in greater detail for some time we’ve just received a set of cards and accessories from Smartcard Focus (http://www.smartcardfocus.com/) including….
- Gemalto GemPC Shell Token V2 (IDBridge K30) (a USB dongle style Smart Card reader which you can see in the screen shot sequence below)
- Gemalto IDPrime .NET smartcard – SIM cut (to go in the IDBridge K30)
- Gemalto IDPrime .NET card – just your standard Smart Card
- Omnikey 3121 – just your standard Smart Card reader
One of the first things I wanted to do was get PIN complexity and policy defined; the chaps over at Gemalto provide a number of tools which can be used to manage the cards which can be downloaded from the links below…
So time to get on with the guide (which also shows you which downloads are needed from the links)!
48 0s typed out… 🙂
Is the desktop dead yet? Well with the 4th Gen Lenovo X1 Carbon (i5-6300U/8GB/256GB) and the ThinkPad OneLink+ Dock it might as well be! This powerful little dock has just a single cable to plug into your laptop which provides power and connectivity to the dock.
For connectivity the dock includes
- On the front…
- Stereo/microphone audio combo port on the front
- 2x USB 3.0 ports on the front one of which is ‘always on’ powered – great for charging up your phone
- On the back…
- 2x USB 2.0 ports (or as I now call them ‘Keyboard and Mouse ports’)
- 2x USB 3.0 ports
- 1x Gig Ethernet port
- 1x VGA port
- 2x (full sized) Display Port 1.2 ports
- Cable to your laptop
- On the side…
- Kensington cable lock
Going by the Lenovo website (Super long Lenovo link) this dock will work with the ThinkPad X1 Tablet, ThinkPad P40 Yoga, ThinkPad Yoga 14, ThinkPad Yoga 260, ThinkPad Yoga 460, X1 Carbon (4th gen), X1 Yoga.
Some super awesome little features that have really helped
- Power on button for the laptop on the dock – even with the screen closed it’ll power on your laptop (just too bad with the screen closed I can’t get to the fingerprint reader!)
- With the Ethernet cable plugged into the docking station the laptop will turn off its WiFi
- The docking station comes with a power cable (thus you don’t have to sacrifice your laptops power cable or buy an additional one!)
- Even though only one of the front ports is ‘always on’ powered the second port has no issues in powering up and running a 500GB Freecom USB Hard Disk Drive.
So as you will have seen from the photos this screen has no issue in running 3x screens; but what about 3x screens while running a video on each screen, hammering the USB 3.0 port on the front running Crystal Disk Mark to a USB HDD, with audio streaming and my phone on charge? I certainly couldn’t notice any issue and the CPU on the X1 stayed below 22% through the test.
In the past I’ve seen docks like these kick out a fair amount of heat (when under load in particular) and while you can feel some heat from the OneLink+ dock it really isn’t much at all (only a few more degrees Celsius above its ‘off state’). In addition some laptops seem to ramp up their internal fan when attached to a dock – in this case the X1 Carbon behaves and under ‘productivity tasks’ I couldn’t notice the fan noise at all.
I would prefer to see the VGA port replaced with a further display port (on high resolution screens VGA really does not work well) the Lenovo ThinkPad OneLink+ Dock really is an excellent bit of kit; not once have I looked back on my desktop and having extra desk space is just an added bonus.
