If you have ever seen this post Server Room – The latest you will notice we have a pretty awesome HPE Aruba 5400R zl2 Core Switch; however (at least until now), I’ve been yet to find a really simple guide which shows the best way to reboot the management modules following a firmware update. So after much research and a… Read more

Setting the Source Interface/VLAN for RADIUS, SNTP, syslog, TACACS, Telnet, TFTP and sFlow on HPE Aruba (ProCurve) switch
If you are running an HPE Aruba (formally ProCurve) switch you may come across cases where your switch (in the example above a 5400R zl2) has multiple IP Addresses/VLANs and you need it to talk to another service (in my case syslog and sFlow receivers) on a set interface. When this occurs you can use the ip source-interface command (make… Read more
Unable to mount the WIM, so the update process cannot continue – MDT on Hyper-V
Not the first time I’ve run into this issue and probably won’t be the last! While building a new Windows Server 2016 (Full) Microsoft Deployment Toolkit server when attempting to run the ‘Update Deployment Share’ wizard I was getting the following error message. Unable to mount the WIM, so the update process cannot continue. The solution is simple; if you… Read more
Mitigating SSH Weak MAC Algorithms Supported and SSH Weak Encryption Algorithms Supported on HPE Aruba-OS Switches
Having recently setup OpenVAS (something I will likely blog about in further detail soon) I have found out that the default out of box deployment of Aruba-OS (formally ProCurve) supports a number of insecure SSH Algorithms with messages similar to the ones below logged even when running the latest firmware releases (YA.16.03.0004 on the 2530 series). SSH Weak Encryption Algorithms Supported… Read more
Panasonic Toughpad FZ-G1
Over the past year or so I’ve come to realise that although my Surface Pro 3 (i5/4GB/128GB) is an awesome machine I just don’t take it out of the house as much as I should be for fear of breaking it. On that note I’ve decided to sell it and in turn replace it with a true beast of the… Read more
HP Color LaserJet CP3505 Printer, after IP address change will not print
While carrying out the steps to move our network devices from a flat network to one with purposeful VLANs I had changed the IP address of one of our HP CP3505 printers (using the web based management console) to discover that with the new IP I could not print to the printer over the network. Oddly enough the web based… Read more
Synology DiskStation as a Backup Target for Windows PCs and Macs
As some readers may know I currently work in Higher Education and while all of the business data is trivial to backup providing any level of backup service to students and academics is significantly harder. The challenges faced include the myriad of Operating Systems in use (Windows/OSX/Linux), the fact that the devices being backed up are inherently ‘untrusted’ (i.e. owned by the… Read more
Flashing lights and HPE ProCurve/Aruba Switches (chassislocate)
When working with a lab full of HPE ProCurve/Aruba switches (or you just want to know who is who in a stack of switches) the chassislocate CLI command comes in really handy by either blinking or holding solid the blue locator light. See the screenshots below for a little more info. ” order_by=”sortorder” order_direction=”ASC” returns=”included” maximum_entity_count=”500″]
Aruba (by HPE) 2920s – pictures
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… Read more
