Installing VMWare Tools (Open VM Tools) on JunOS SPACE 16.1 or newer

These instructions are for JunOS SPACE 16.1 or newer. I also have instructions for JunOS SPACE 15.2 or older. JunOS SPACE, Juniper’s management tool for JunOS devices (switches, routers, firewalls), officially supports Open VM Tools for management from ESXi. Unfortunately, Juniper’s instructions are to build Open VM Tools, and that won’t work without a dev environment, …

JunOS SPACE upgrade hangs at 0%

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 …

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. Bob was the only one who had the admin password (for ssh / CLI access) to your JunOS SPACE installation. After vowing to do better in future and storing all infrastructure passwords in some form of centralized, encrypted, backed-up password …

Restoring Extreme Networks Netsight user login

In Extreme Networks’ Netsight management appliance, it is possible to configure external authentication (LDAP or RADIUS) and not set it to “fail to OS,” which is a checkbox that is unchecked by default. If your LDAP or RADIUS server is down, or if you made a mistake entering settings, you’ve just locked yourself out of …

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 …

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 …

Compiling 64-bit mpir using VC++ 2008 Express

MPIR is a Windows-friendly fork of GMP. It can be used as a direct replacement of GMP. I wanted to have my pycrypto build use _fastmath, and that meant having GMP support. Building a 64-bit version of MPIR is fully supported in Visual C++ 2010 Express. Not so, alas, for Visual C++ 2008 Express. The …

ipv6 at home / small office: Verizon FIOS IPv6 trials

Verizon FIOS has entered into a month-long IPv6 trial on April 6th. It is a dual-stack trial carried out with Verizon employees in Reston, Virginia. The “custom CPE” that are mentioned in the article reflect the fact that precious few home routers have full, or even partial, IPv6 support at present. With both Verizon and …

Warranty agreements for PC graphics cards

This post is to serve as a place for me to keep track of how different graphics card manufacturers handle warranty – in the US, that is, I’m not tracking Europe at all. Next time a graphics card fails on me, I’d like that to be an easy process. After compiling this, it’s a pretty …
