Reset Avaya System Manager Password

Working with the Avaya Aura System Manager (SMGR), you will eventually find yourself locked out of the web GUI. This most commonly happens if a password times out, and the ‘new’ password change goes unrecorded. The following steps will outline how to reset the admin password for Avaya Aura System Manager web GUI.

These steps were used in conjunction with Avaya Aura System Manager version (deployed from System Manager Mid-Size Enterprise 6.2.2 template with SP4). See the end of this posting for any other software (and corresponding versions) used in conjunction with these steps. I’m certainly they’ll work with […]

Installing VMware Tools from the Linux CLI

This posting outlines the steps required to install VMware Tools in a Linux environment. Specifically, it lists the commands that should be issued at the command line to mount the VMware Tools CD-ROM image, unpack, and then install the VMware Tools tarball.

While these steps should work in almost any Linux environment, I created them using the Linux Mint OS. Mint is a fork of the Ubuntu project. Ubuntu has its roots in Debian. Check out the Linux Mint OS if you are looking for a friendly Linux GUI.

The only caveat that should be observed is that some Linux distributions […]

VMware VM – ‘I moved it’ vs ‘I copied it’

If you’ve worked with VMware products before, you may have (at at some point likely will), encounter a pop-up similar to this one.

What is it asking? What prompted this question? Why does VMware want the default to be, ‘I copied it’? The short answer is that VMware ‘thinks’ that it is possible that this VM was cloned from a pre-existing VM (i.e. ‘I copied it’). If that is the case, VMware needs to change the unique identifiers within the cloned machine, so that potential hardware & software conflicts are avoided. Choosing ‘I copied it’, therefore, is preferred over ‘I […]

traceSM – Avaya Aura Session Manager

You can learn quite a bit about how the Avaya Aura Session Manager works (or doesn’t work) with the built in packet capture tool, traceSM. If you’ve ever worked with this tool, you may have experienced the following error while trying to launch it:

ERROR: traceSM is already running. Only one instance is allowed.

This error can occur if an admin does not exit the trace tool or terminal session properly. It can also occur if some other administrator is currently running traceSM. By default, Avaya does not want customers launching multiple instances of a potentially resource intensive application, like a […]

Avaya Compatibility Matrix – How to patch Avaya products

Anyone that works with Avaya products should know about the Avaya Compatibility Matrix. It is Avaya’s tool for navigating through the onslaught Avaya patches, service packs, and feature packs.

It is a bit hidden on the Avaya website, which is why I’m writing a blog post on it. There is a link to it hidden on the bottom of the Avaya Support page, or, find it by clicking here. Note, you’ll need to log in with your PLDS credentials to get access to the site: Avaya Compatibility Matrix

Once you are logged in, choose the platform you are interested in […]

Star Trek The Rewatch (podcast)

“Star Trek The Rewatch” is a podcast I discovered while laid over at O’Hare International on the way back from a week of teaching SIP & Voice over LTE. Each show is devoted to a discussion of a single episode of Star Trek The Next Generation. The episode is reviewed for likability, but also has the science presented within critically examined, as the hosts are both astrophysicists at Oxford. Graeme McRae and Robert Simpson cheeky rapport and infectious laughter is plentiful as they praise and admonish the scientific blunders compounding the voyage of Jean-Luc Picard’s Enterprise.

If listening to […]

Driver installation order for a Dell Latitude E6420

I recently rebuilt a friend’s Dell Latitude E6420. After a fresh Windows 7 install, I installed the relevant drivers in a haphazard manner, and found that many of the devices were still failing to be recognized in the Windows Device Manager. After a quick Googling, I found that Dell has a specific order that must be observed when the drivers are installed onto the laptop after a fresh Windows install.

Just in case anyone else is looking for this information, I thought I’d repost it. Remember that your laptop may not require all of the following drivers. For example, if […]

    SIP response codes – Difference between ‘603 Decline’ and ‘486 Busy Here’

SIP response codes – Difference between ‘603 Decline’ and ‘486 Busy Here’

While lecturing on SIP response codes, I’ve had several students ask for an explanation of the case usage for a ‘603 Decline’ and a ‘486 Busy Here’.

The short answer is that all 6xx responses will terminate SIP dialog, and any pending searches. Alternatively, a 486 response would indicate that the user is not available at a particular request-URI.

I have constructed a video that demonstrates the difference between these two responses. It might even answer a few questions you didn’t even know you had.

How to replace or remove lines with REGEX in Notepad++

Notepad++ is a practical text editor that is used by many Computer Science & IT professionals. You can download Notepad++ here.

I had a student that asked how to remove ‘commented’ lines from an Avaya configuration file (46xxsettings.txt) using a Regular Expression (REGEX), and Notepad++ (that is to say, delete any lines that began with a # character). I thought this was a practical enough trick to post on my blog, as you can tweak this simple REGEX string to remove, or modify, any lines from any text file you might be interested in manipulating.

1) Open the file you wish […]

    How to flash Asus RT-AC66R or Asus RT-AC66U with DD-WRT open source

How to flash Asus RT-AC66R or Asus RT-AC66U with DD-WRT open source

I returned from running a two week long SIP training event in Calgary to find my DD-WRT flashed Asus N-16 router had suffered a lightning strike in my absence, and was no longer functional. Not being able to survive without a router, I headed out the Best Buy to find the best DD-WRT capable router (with an AC radio) currently available in a big box store. I ended up with the Asus RT-AC66R (also called the Asus RT-AC66U).

The Asus RT-AC66R (or RT-AC66U) supported by the DDWRT project. Available on Amazon, New Egg & BestBuy. The correct way to […]
