I attempted to upgrade a JunOS SPACE instance from 15.2R1 to 15.2R2. It would sit at “upgrade process has not started” and 0%. If I changed the URI to the base, I’d be back in the SPACE GUI as if nothing had happened and I had never entered maintenance mode. This was caused by a …

“Cyber Security” for home PCs
Concerns about online security are widespread. No-one wants their logins and finances compromised. How to act on those concerns can be confusing. How security pros and general users go about securing their devices is quite different. Users often rely on software such as AntiVirus. Security pros likely also use AV, but it’s not their first …
Convert Windows boot from BIOS to UEFI without decrypting Bitlocker
I wanted to convert an MBR/BIOS boot drive to GPT/UEFI, but without needing to decrypt and then re-encrypt Bitlocker. Mainly because I am lazy. This worked, but I’ll warn that the advice to decrypt completely first is without any doubt the safest way to go. Follow the instructions for converting from BIOS to UEFI boot. …

Change admin user password expiry on JunOS SPACE
The admin user on JunOS SPACE, which is used for ssh / root access, has a default password expiry of 70 days. This may not be desired. NB: An upgrade of the JunOS SPACE platform will set the admin password expiry to the default of 70 days again. To avoid the admin user password being …

Reset admin password on JunOS SPACE VM
Picture this: Bob, your JunOS SPACE administrator, left the company. IT diligently wiped his laptop.

Canon EOS utility causes high “System” CPU, network meltdown
This is one of those slightly odd ones. I had high CPU on my PC even when not running anything, 20-25% (one whole core in essence) taken up by “System”. Mouse responsiveness was sluggish, sound would stutter, the works. I tracked it down to ndis, and my Ethernet driver, using Sysinternals Process Explorer. Other folk …

Installing VMWare Tools on JunOS SPACE 15.2 or older
[Edit 2017-05-04] The below is still valid for JunOS SPACE 15.2 or older. From JunOS SPACE 16.1 on, you can use “Open VM Tools” instead. JunOS SPACE, Juniper’s management platform for JunOS devices (switches, routers, firewalls) does not come with gcc or kernel-headers. Installing VMWare Tools from a mounted ISO via vmware-install.pl is not all …

Resolving JunOS Pulse install issue on Windows
Edit 2017-12-05: This remains one of the most visited entries on my blog. The notes here do apply to Pulse Secure, and checking the output of pnputil, Pulse Secure did not bother to change the “Driver package provider” string, which means it still reads “Juniper”. Tsk. On my own Windows 7 machine, I had an …
