Pleasantly Suprised by Airport Extreme Update from Version 7.4.2 to 7.6.9

I have two Airport Extremes, the earliest version (1st generation, 2004 – 2008) which I can no longer upgrade / update,  however, I was pleasantly surprised when the other, a 2nd Generation 2008 – 2012 offered an upgrade to version7.6.9.

I have often tried to upgrade the older one (first generation), only because each time I manage it I’m advised that there’s an upgrade available and I’m asked if I would like to upgrade, but whenever I attempt to update I’m disappointed to by failure..

So when the newer on (second generation) offered to update from version 7.4.2 to version 7.6.9 I was sceptical at first, then sufficiently hopeful to take this screenshot, and then pleasantly surprised when it successfully upgraded.

Linux Reliability: 464 Days Uptime.

Between 2001 – 2003 I managed a number of Sun Spark and RedHat Linux Servers for a company called Lost Wax that build and designed and hosted Java Applications for large companies in the United Kingdom.

The four front facing firewall were based on Red Hat Linux 6.1 had a number had a number of security tools, like tripwire installed on them on them and allowed limited FTP access from an ISDN link from our premise in Richmond, London.

One of the server, after 464 days began to behave erratically and I logged a service request with the RedHat Linux office which at the time was based in Guildford Surrey which was also the town where I lived.  At the same time I asked a Question on Linux Questions.

Here is the Question I asked in January 2002, the Server at the time had been operational for 464 Days.

Moodle Consulting with Chad Outten: July 2018

It was wonderful to have Chad Outten on site at the College for three full days of consulting.

We revisited out Moodle installation which as been running “in various guises” since 2007 when it was first installed at our College.

Moodle eLearning Team Glasshouse 2018

The scope outline was to achieve the following.

  • Conduct a technical audit of your Moodle system using our 33-point checklist;
  • Prepare a technical report with recommendations to improve data security, information privacy and site performance;
  • Conduct an e-learning audit of your Moodle system using our 47-point checklist;
  • Prepare an e-learning report with recommendations to improve usability, engagement and learning experience

We expanded the scope and agreed that we would also include and address at the following.

  • (re)configure moodle site settings to improve data security, information privacy and site performance
  • (re)configure moodle course settings to improve usability, engagement and learner experience
  • evaluate teacher practice on the current moodle site based on key metrics: learner experience, course design, communication & collaboration, assessment and web responsiveness
  • deploy moodle to a test environment and build a proof of concept for the ‘new’ moodle
  • identify moodle knowledge/skill gaps and facilitate a practical workshop for staff which targets a specific area eg. assessment, reporting or mobile learning design

Draft Proposal and Recommendations

4.0 Recommendations

Based on the aforementioned challenges and objectives, the recommended course of action is as follows:

Administration. Streamline administrative workflows for course creation, user enrolment, group assignment, teacher role assignment. To improve efficiencies, these processes can, at the very least, be manually batched on a periodic basis or automated to some extent.

Simplification. Reduce system complexity for teachers. This means disabling features/functions in Moodle’s site configuration, that are not essential at this stage. On the same token, (re)setting the global defaults for course settings, activities and resources – will reduce the unnecessary decision-making for teachers. Moreover, creating a course backup as a ‘template’ which can be restored as a new course, 

Baseline. Establish a baseline for Moodle best practice. And mandate this as a minimum expectation for all staff. For example, as a minimum standard, all teachers are expected to upload assessment sheets, setup assignments for electronic submission, enter grades and feedback directly via the LMS, track assessment completion, setup student feedback and issue badges for successful course completion.

Collegial approach. Form an E-Learning Team. This is a select group of highly capable teachers, across a range of year levels and KLAs, who are allocated time release, to meet as a team on a regular basis, champion e-learning best practice, deliver professional learning opportunities and 1:1 mentoring for colleagues in their KLA.

Time investment. Invest in structured release time for teachers to participate in regular professional learning opportunities delivered by the E-Learning Team. For example, Assessment: assignment, quiz and workshop; Communication & collaboration: forum, glossary and messaging; Grades: grade book, grading and feedback; Badges; Reporting; Mobile learning etc. 

Reporting. Configure and utilise reporting functionality to better measure the outcomes of learning. This includes tracking key activities, such as assignments, in courses and aggregating said activities toward course completion. As a result, teachers will be able to view relevant reports and better gauge student participation and progress, and intervene with ‘at-risk’ students, in a timely manner.

Showing off my Extreme Gear: A Visit from Genesis

I’m deeply thankful to all the schools who have allowed me to visit and learn from them over the past 12 or 13 years, and so it was an absolute delight to have Neal McArthur both friend and CT Operations Manager at Genesis Christian College dropped by to have a look at some of the things we are doing at Glasshouse Christian College.

I’ve visited Genesis a number of times since 2004, when I first set up technology at our College About 13 or 14 years ago, I would drive down and ask them all I could think of about school technology, however since those days we have made significant progress in all area’s of technology including Networks.

We showed talked about extreme networking issued and exchanged notes out our experiences and showed him all we could in Extreme Management Centre, and particular the depth of analytical data we are able to visualise the health of and activities on our School Network.

The Extreme Management Centre is a single pane of glass management system that provides wired/wireless visibility and control from the From the Core to the Edge, or in other words from the data centre to the mobile edge.

Footnote: If you are interested in Extreme Networking please feel free to give me a call to discuss, If you’re part of an education organisation I would be more than happy to show you what we are doing with our Extreme Networking Gear.

Installing two Lenovo ThinkSystem Servers (SR630)

It’s a rainy Saturday, 24 February 2018 and Scott and I are installing two Lenovo ThinkSystem Servers (SR630).  My other 2 Lenovo Servers gave me 5 years of Service and are still in excellent working order.

Scott is an absolute expert and once these ThinkSystem Servers are installed I will most likely never need to do a single thing to them for another next 5 years.

Note:  I always purchase onsite warranty and as much server memory as I can afford at the time,  these servers will be connect to about 40TB of EMC Storage.

My old Lenovo (IBM) Servers were spend the last 5 years running VMWare vSphere with over 30 instances between them, and seldom went over 9% System (CPU) Usage.

I investigated a number of other solutions including Hewlett Packard Servers and I considered a Hyperconverged  solution on either Simplivity and Nutanix  running on Dell, Lenovo or HP Gear, but I have chosen to keep things as simple as possible.

Sophos Health Check

I’ve had Sophos installed at our college for the past 5  years and we are in or sixth or seventh year of using Sophos Firewall and Anti-Virus across our campus.

I purchased two consecutive on-site days from Sophos, who flew one of there top Security Engineers from Sydney to stay with us for two days and complete a thorough investigation and health-check of our  Sophos installation.

I was delighted with the results.  

Very Briefly

  1. Firmware Upgrade –  We upgraded to the newest firmware version of Sophos UTM.
  2. We simplified our firewall rules and disabled and deleted 18 unwanted access rules,
  3. Reporting Improvements, –  we significantly improved and tweaked our reporting.
  4. We investigated upgrading to a hardware appliance.
  5. Removed unnecessary STAS software from servers
  6. Removed unnecessary RADIUS servers  (we use Extreme Radius)
  7. Cleaned up Admin accounts and assigned personal accounts of all the admins to administrator profile.
  8. Rule Creation and Policies: Improved the way we create rules by teaching us  how to create multiple user activities and assign to different user groups in the same policy rather than creating different web policy for each and every user group.
  9.  Cleaned up application control policies and changed it as per requirements.
  10. Removed irrelevant OS from the IPS policy
  11. Sync App Control – we enabled sync app control and we were able to see new apps getting detected by the firewall. – to be categorised.
  12. Device Access – Disabled SSH access on WAN and created Access List to allow specific IP’s
  13. We investigated the future use of Sandstorm (cloud sandboxing).

Our security installation at the current time comprises of the following,

  • XG Firewall – Next Generation Firewall.
  • Intercept X – a signatureless anti-exploit, anti-ransomware, and root cause analysis protect your endpoints from advanced threats.
  • Sophos Endpoint – Client Protection which doesn’t rely on signatures to catch malware, which means it catches zero-day threats.
  • Sophos Phish Threat – User education by effectively simulating realistic and challenging phishing attacks in a just few clicks.

Sophos Consulting and Health Check

Relationship Benefits: The two days of Sophos consulting provided an opportunity for us to strengthen our relationship with Sophos.

Third Party Consideration: The two day has forced me to re-consider the benefits of 3rd Party to deploy and configure Sophos.

My own thoughts are that using a Sophos Product Engineers far outweighs the advantages of using a 3rd Party Engineer, so even if you have had a third party work on you installation, – you will receive significant advantage for using Sophos directly.

Recommendation: If you are a Sophos user and run a large installation I would highly recommend spending the money and getting one of the Sophos Engineers spend a few days on site checking out and tweaking your system

TP-LINK PowerLine Network Wi-Fi Range Extender Review

TP-LINK home products both inexpensive and easy to use. They offer a rich set of technical features making them good value when you consider all their features versus cost ratio. Generally speaking there are plenty of regular firmware updates as well as community support and help available when you need it. (I’m a fan of TP-Link for home use, but not for commercial use).

Currently I’m use two TP-LINK AV200’s with two TP-LINK AV500’s and yes they work well together. In fact you can even mix different speeds with different vendors, so for example you can mix a TP-LINK AV500 with an EDIMAX AV200 (of course it’s never a problem till it’s a problem, my view is that technology should just work, and I have no hesitation or regrets about mixing them).  

Another great feature of the TP-Link gear is that the AV200, AV500 and AV1000 offer  Energy Savings of up to 85%.

  • TP-Link TL-WPA4220 KIT (AV500)
  • TL-PA211KIT  (AV200)


I’m more than happy with TP-link, easy to set up, easy to find support, easy to locate products, easy to upgrade or dispose of if they do not quite work as expected.
