While iterating through an issue with our Ruckus SmartZone (with Ruckus R510 Access Points) controllers I was looking for a way to see when the Access Points had applied the new configuration; lone behold it’s quite easily done through both the CLI and the GUI.

Anyone who has used the new SmartZone controllers will know all too well that’s it’s not the fastest GUI to work with – thus if you have the option I’d suggest you go with the CLI method which is very responsive (and much more consistent!).

Via the CLI

Via the GUI

So over the last few hours I’ve been making some config changes to our Eaton UPS Network Management Cards that require the magical ‘Reset Communication’ button to be pushed in the web interface (one day I must get the management software!). To help speed up the process (or at least know when I should reload the page) I timed the process; so as more of a reference to myself than anything else the results are…

Web interface will respond and provide an authentication prompt: About 2 minutes 10 seconds after button push
Web interface will display all UPS data: About 2 minutes and 30 seconds after button push

After a great many years since Custom RemoteFX RDS Farm it’s time for something new! After much discussion and looking at the working practices at my current place of work we’ve decided to go all in with RDS and to support that we’ve got 3 new servers to run it on.

2x 1U rack mounts to go in our main server room with 1x tower for our DR room.

Photos below and more details to follow!

For a little while now we’ve had issues with the uniFLOW Server service (version 5.3) not starting in a timely fashion (2hrs+).

After a harrowing tale of working with their support going in circles looking at issues with SQL Server and suchlike we worked out that the issue seemed to be caused by stale files at ‘C:\Program Files (x86)\Common Files\NT-ware Shared\ActiveJobs’ some of which were many months old or 0KB in size.

Ultimately the solution was to stop the Uniflow Service (force quit it using Task Manager if it’s still in a broken ‘starting’ state) and then delete the contents of that folder with the exception of the readme_activejobsfolder.txt file (which mentions that you shouldn’t do anything to these files!) and then start the uniFLOW Service service (which started up in a few minutes).

While provisioning some new Ruckus R510 WAPs onto our SmartZone 100 (5.0.0.0.675) we’ve had a number of cases where the WAPs will reboot for their firmware update but will not proceed beyond that point. In particular the PWR and CTL lights stay lit but the radio lights do not come on at all.

Looking in Access Points > Affected WAP > More > Tunnel Diagnostics (we’re using AP tunnelling) I note errors along the lines of

ifconfig: gre1: error fetching interface information: Device not found

cat: can’t open ‘/proc/rksgre/gre1/stats’: No such file or directory
cat: can’t open ‘/proc/rksgre/gre1/cache’: No such file or directory
cat: can’t open ‘/proc/rksgre/gre1/cfg’: No such file or directory
cat: can’t open ‘/sys/kernel/debug/qca-nss-drv/stats/*’: No such file or directory

The solution thus far has been pretty simple – factory reset the WAP by pressing and holding the RESET button in the back for 6+ seconds. It’ll go through a process of about 5-10 minutes and thus far have been coming back in a functional state.

Normally the little 8 (well 10 if you include the ‘uplink’ ports) port switches we buy end up under a desk or on a shelf but for a one off we’ve got one going in a comms cabinet. Quite luckily the HPE Aruba 2530-8G come with the ears in the box to do this (I recall seeing some models of switches with this being an additional item or needing a special shelf).

You’ll still need a place to keep the power supply but that’s nothing a few cable ties can’t sort!


Today I had the pleasure of presenting at the Oxford ICTF Conference on Multi-Factor Authentication and Password Stores with Smart Cards and YubiKeys, the video recording is online now here – https://youtu.be/WGtCxS2YFNA and the presentation can be downloaded through the link below.

A special shout out goes to the Yubico press office for providing a set of YubiKey 4s, YubiKey NEOs and Security Keys which helped fuel a very lively Q and A session!

Yes! Yes it they do!

In preparing for a presentation to some peers in the wider IT community tomorrow I have access to some YubiKey Neo authentication keys; in doing some extra reading up on the keys I thought – I wonder if these work with the MIFARE readers (note that these are MIFARE readers not the proprietary Paxton only readers) that are part of our Door Access Control system.

Lone behold they do; in the revision of the keys we have it’s a NXP MIFARE Classic 1k chip.

Recently I was inspired to take on some more information about routing and the associated protocols. To help support that I’ve gone and bought a Mikrotik RouterBoard hAP ac from Amazon (along with a RouterBoard hAP Lite). I hope to kick out a few blog posts on it along with my learning points over the next few days/weeks.

In the meantime enjoy the photos!
