Proxmox – the foremind

proxmox-logo-150x150-8355840If you have just installed the most recent release of the virtualization platform Proxmox, you might have noticed the that steps to disable the subscription pop-up dialog have changed, well, other than actually purchasing a subscription, I suppose.  I have chosen to not purchase a subscription for the same reason I don’t have one for VMware’s vSphere Hypervisor, I am not running this in a production setting that requires paid support or premium features. The following steps will disable the subscription pop-up.

Backup the javascript file

The pop-up contents, and whether or not are displayed, are controlled by a function in a javascript file.  The first step should always be to make a backup, just in case Murphy rings your doorbell.

root@pve:~# cd /usr/share/pve-manager/js/
root@pve:/usr/share/pve-manager/js# cp -p pvemanagerlib.js pvemanagerlib.js_backup

Edit the javascript file

Open the pvemanagerlib.js file in your favorite editor.  If this is a vanilla, unmodified installation, skip to line 850.  If this is not the first time that you have edited the file, search for the first occurrence of the following snippet, which will be in the function that we need to alter:

gettext('No valid subscription')

The text of the check for the function should be altered so that the conditional for the check reads as follows:

before

if (data.status !== 'Active') {

after

if (false) {

Notes

As I stated in the original paragraph, the specifics apply to v. 5.1-3 and that the location of the file has changed from previous versions.  A good way to find the file is to use the locate command, which you will have to install first:

root@pve:~# apt-get update

As you can see the mlocate package makes finding the file so much easier.

WordPress – the foremind

cookiebot_featured_image-e1526150506967-7320834As the whole GDPR craze has hit my place of employment, I decided to look into an easy method for to add a privacy policy and cookie policy to my WordPress site.

Adding a privacy policy is pretty simple, all you have to do is to create a new page with the policy on it.  Simple right? Well, it turns out that the devil is in the details as normal.  After a few minutes of research, I found a nice site with a template-based policy generator.  The site, Privacy Policy Template, is pretty self-explanatory.  The code for the template is very easy to edit after you generate the code.  This provides a great starting point for sites that need more information, but also a nice final product for blogs like this one that don’t really deal with any user data other than the owner.

The other shoe is a cookie policy.  Towards this end I used the CookieBot service and the accompanying plugin.  It is a paid service if you have a large number of pages, but if you have a site with 100 sub-pages or less then the service is free.  Be aware that for the purposes of billing and scanning, CookieBot treats each post or page as a separate item.  The pricing structure is really quite reasonable given the capabilities of the service.  For example, this site has a total of 121 pages and posts, so they automatically upgraded my account from free to a 30-day free trial.  Until I hit 500 pages/posts, the cost is only $10/month, which in the overall scheme of things is not that bad at all.

cookiebot-300x212-3514927 Screenshot of slide-down panel with default settings.

The initial scan can take as long as 24 hours to be generated, however that all depends on the size of the site being scanned.  The cookie categories and reports are automatically created for you, however you can also customize the panel with custom cookies and categories, as well customizing the CSS to control the look and feel of the panel.  I choose to start out with defaults only.  The image to the right is what my site looks like after the initial report was generated.

I also received a report in the inbox configured for the account with details on what was found in the scan and which cookies were treated as falling into the pre-defined categories.  For example, the scan found two cookies that were designated as necessary for the site to function.  There were also items found in the preferences and statistics categories.

While I don’t really feel that it is necessary for me to even have a privacy policy or cookie consent feature, I have decided to do it anyway simply out of an attitude of prevention, due to the political climate surrounding personal data collection and the like. (Thanks, Mark Zukerberg, as well as your friends at Cambridge Analytica.)

While these two services are by no means the only ones out there, I found them to be the easiest and simplest to implement.

open-source – the foremind

May 17, 2018May 11, 2018 by Andrew Fore

According to the FileZilla FAQ:

FileZilla is free open-source software distributed under the terms of the GNU General Public License free of charge.
Basically this means that everyone, including corporate entities, can use FileZilla, including but not limited to private, educational and commercial use.

When you install it you have to opt out of at least one, if not two, bundling offers.  While many installers provide you the opportunity to install a bundled offer, I really think that if you are releasing the software as open-source under the GPL, then you should embrace the spirit of the license and make the included bundles opt-in.  And why you are at it, maybe you could add a section to the FAQ on what the funds for the bundles and the website sponsors are used for.

Reviews – the foremind

Lately I have been dipping my toe into the pool of home automation and smarthome technologies.  While I have been interested in having a smarthome ever since I watched my first few episodes of the SyFy channel show Eureka.  My interest was advanced even more by Google I/O 2016 and the demo of Google Assistant.

So a few months ago I ventured into this new world of technology (new for me at least) cautiously by purchasing a pair of the LIFX White 800 smart bulbs that were on sale at Walmart due to the release of the LIFX Generation 3 A19.

I found that the Android app was very easy to configure, and that I could easily add the light bulbs to multiple Android devices.  I was disappointed to find that they were not immediately compatible Siri on my wife’s iPhone due to the lack of a suitable homekit bridge/hub.  This was remedied easily enough by configuring the open-source NodeJS server homebridge and a plugin (homebridge-lifx-lan or homebridge-lifx)  to connect the light bulbs to the Apple Home application.

Adding the lightbulbs to the LIFX app on my Pixel was fairly straight forward and went off without a hitch.

I have found the light bulbs easy enough to manage.  The hue range and brightness are quite suitable for the application, namely the nightstand lights in the master bedroom and I would definitely recommend these to anyone that doesn’t have a need for more than just white led light bulbs.

ESXi Embedded Host Client Overview

As I have begun to see numerous rumors in the VMware forums that the next major release will deprecate the usage of the vSphere thick client (and the simple fact that VMs created using the most recent extensions include features that cannot be managed with the desktop client) I decided to take the plunge and install the HTML5 fling host client on my ESXi host.
The fling can be downloaded from the VMware Labs site. The standard caveat applies to this fling like anything else that you install from VMware Labs:

I also understand that Flings are experimental and should not be run on production systems.

Configure Google Authenticator on CentOS 7

Image of laptop with hand holding a skeleton key extending outwards through the display.

Intro

As part of the rebuild on my Plex Media Server using CentOS 7, I had intended to configure Google Authenticator but hadn’t gotten around to doing it yet.  As I got into the process recently I discovered that many of the steps that I had used when configuring my CentOS 6 Digital Ocean droplet were out of date to the point of uselessness.

I also discovered that most of the guides that I found either relied on the older 1.0 code release which was also outdated or used a unknown RPM repo.  As such I decided to write up the process that I followed to use the code downloaded from the official GitHub repository.

NOTE: If you are doing this in an enterprise setting, it is likely that your company has particular settings and restrictions that you may need to adhere to (e.g., not running things as the root user). Also, please note that all of my examples use the CentOS defaults unless specifically noted.

Switch your domain registrar to Hover

6722541653_98d7b2b922_m-7197801There is an adage that you should vote with your wallet when you are unhappy with a particular business or their practices.  Do we do this as much as we should?  Probably not.

Taking this to heart,  I have decided that I will try to apply this to the usage of my electronics and gadget stuff.  So the first thing I chose to do was to switch my domain registration from using NameCheap to using Hover.  There were several usage reasons, like support for the TOTP/HOTP system for two-factor authentication instead of relying on SMS messages.

But there are some other reasons, like the support for causes that I feel are worthwhile.  Here are just a few that Hover is a patron of:

So if you own a domain or two, or you work somewhere that does, think about switching your registration to Hover and help support not only your account’s security but also some great organizations.

Gratuitous Recommendation Link: https://hover.com/Ems0HmPv

Full disclosure: I work at Web.com and they are the parent company of Register.com and Networksolutions.com, two really large domain registration companies, but I still prefer Hover.

RHEL7 and ncat changes

One of the tools that I use on a regular basis to test network connectivity updates is the “z” option of netcat.  Apparently when RedHat rolled out the latest version of their distribution of RedHat Enterprise Linux (RHEL) they decided to move to using the nmap-ncat package instead of the nc package.  The command options a very different.

So when attempting to test single port like I would have under previous releases I now use the following syntax:

# echo | nc -w1 $host $port >/dev/null 2>&1 ;echo $?

If the result that is returned is a zero then you have successfully connected to the remote host on the desired port. This also applies to CentOS 7 since it is a “clone” or copyleft port of the RHEL7 binaries.

Dear Comcast: You Suck

Editorial Note: Apparently Comcast really would prefer that people not use the term data cap when referring to the limitations being placed on their customers data usage and would much rather prefer that we use the term data usage plan or data threshold, however, I don’t really care. 🙂

Dear Comcast,

I would like to go on record as saying that you suck.  I recognize that you are a for profit company and that you would like to make a profit on the services that you provide.  I even think that having your company make a profit is a good thing because that enables you to pay your employees so that they can put food on their tables and afford to pay the fees for their children to participate in Little League baseball and other such childhood activities.

Your data usage cap system is bogus.  According to the data available on your own website you have eight (8) different trial markets where you have rolled out data caps since 2012:

  • August 1, 2012: Nashville, Tennessee – 300GB cap
  • October 1, 2012: Tucson, Arizona – 3 tiers (300GB, 350GB, 600GB)
  • August 22, 2013: Fresno, California – Economy Plus option added
  • September 1, 2013: Savannah, Georgia; Central Kentucky; Jackson, Mississippi – 300GB
  • October 1, 2013: Mobile, Alabama; Knoxville, Tennessee.
  • November 1, 2013: Huntsville, Alabama; Augusta, Georgia; Tupelo, Mississippi; Charleston, South Carolina; Memphis, Tennessee – 300GB cap
  • December 1, 2013: Atlanta, Georgia; Maine – 300GB cap
  • October 1, 2015: Fort Lauderdale, the Keys and Miami, Florida – 300GB cap plus $30 option for increasing to  unlimited

In fact, your page on this even refers to these as “trial start dates” which to a reasonably minded person would imply that they have an end date as well, however to the best of my knowledge (as well as the comments made by a customer support representative) there is no plan to end these trials OR any plan to actually collapse them into a single cohesive plan that applies to your entire service.

Massive Numbers of Chrome Helper Messages in system logs

Today when attempting to figure out why Google Hangouts would not start on my Mac after the application was re-enabled due to a permissions change, I noticed a large number of messages like the following:

6/10/15 10:20:14.000 AM kernel[0]: Google Chrome He (map: 0xffffff804da160f0) triggered DYLD shared region unnest for map: 0xffffff804da160f0, region 0x7fff99a00000->0x7fff99c00000. While not abnormal for debuggers, this increases system memory footprint until the target exits.

After some research I found that this is a reported issue in the bug tracker for Chromium.  At first I thought that maybe this was the cause of the problem I was having but that turned out to not be the case, simply removing the Hangouts app in Chrome and re-adding it fixed my issue.  However, the sheer number of these errors makes the log a bit unwieldy.  It turns out that there is a way to hide all these messages (thanks to the commenter in the Chromium bug thread!):

[code language=”bash” light=”true”]sudo sysctl -w vm.shared_region_unnest_logging=0[/code]

While it doesn’t help at all with Chrome’s memory issues or other UI issues on Mac OS X, it is rather nice to hide all those spurious messages from the system log.
