vYetti – Fun animated vSphere Login UI customization

05/15/2018 by William Lam 10 Comments

For those that have been asking about how to customize the vSphere Client Login UI to include this fun little animated login screen as shown below, you can find the complete instructions on my github repo: https://github.com/lamw/vyetti-vsphere-client-customization

I wanted to take a moment and give thanks and credit to the original author (Darin S) who created the animated login, which he referred to as an "Animated SVG Avatar". I remember seeing this on my Twitter stream a few months back where it was shared on codepen.io, which is a platform for web developers to easily show off their demos. From what I could gather, the original demo had used MorphSVGPlugin.min.js which is a Javascript library that provided the animation. Apparently, the use of this library required a membership which prevented anyone from consuming this outside of codepen.io for demo purposes. While searching online, I accidentally stumbled across another similiar project by Balram Chavan who developed an alternative solution simply using Angular 5. With Balram's solution, I was able to make the necessary minor modifications (thanks to Jeeyun from the Clairty team on helping me with some of my Anuglar questions) to get this fully incorporated into the vSphere Client UI. I am sure there are other improvements that can be made to the customization such as a more "clarity" look/feel as the old the old "blue marge" theme background is pretty dated but I will leave that to someone more creative than me 🙂

Cool browser plugin for Dark Theme vSphere H5 Client

05/12/2018 by William Lam 3 Comments

While catching up on my news feed early this morning, I came across a really slick browser plugin developed by Jens L. that enables a "Dark" theme for the vSphere HTML5 Client (h5client). If you use either Chrome or Firefox, simply visit Bery's Github site here to get a link to the plugin.

Once the plugin has been enabled, simply login to your vSphere H5 Client, this works using vSphere 6.5 or latest 6.7 and you should see the UI automatically render using the Dark theme without any modifications to your vCenter Server. I know the Clarity team is working on an out-of-the-box Dark Theme for the H5 Client, but until then, this is an excellent workaround. I definitely appreciate this as someone who does work either super late at night or super early in the morning and although I use things like Flux to reduce the brightness of the screen, having a proper dark theme also helps. Thanks for the awesome project Bery!

Here is a screenshot of my vSphere 6.5 environment, which I was able to make use of new theme morning 🙂

If you have any feedback or comments, feel free to post an issue on Bery's github project.

Changes to vSphere Client Login UI customizations in vSphere 6.7

05/09/2018 by William Lam 8 Comments

For those that have customized their vSphere Client Login UI using the instructions here and here, it looks like the process can not be applied to the vSphere 6.7 release. From what I can tell, it looks like we have now consolidated the various WAR files into a single file /usr/lib/vmware-sso/vmware-sts/webapps/ROOT.war. The original contents of the websso directory, which pertains to the UI customization, is now located here. This was a fairly minor change, but something to be aware of and for details on how to persist your configuration changes, please see the instructions below.

Disclaimer: This is not officially supported by VMware. If you decide to enable this, please use at your own risk and ensure you backup all original files in case you need revert back to the original configuration.

As part of looking into this, I also had some fun incorporating a cool little animated login page directly into the vSphere UI which I had shared on Twitter yesterday. Stay tuned for more details on #vYetti 🙂

Changing “Password will expire in X days” notification for Active Directory users in vSphere Web/H5 Client

11/17/2017 by William Lam 1 Comment

When logging into the vCenter Server using either the vSphere Web (Flex) or H5 Client, one of the validation checks that is automatically performed by the server is to check the current users password expiry. If you account expiry is less than the current password expiry configuration, then you will see the yellow notification pop up at the top stating:

Password will expire in X days

This is definitely a helpful feature to have automatically built into the vSphere UI and the default expiry actually depends on the type of user logging into the system. This last part is sometimes confusing as folks mix up the default Single Sign-On User Expiry with the Active Directory user expiry which is completely different.

Single Sign-On Users

For SSO Domain (vsphere.local by default) users, the password expiry AND notification by default is 90 days. This can be configured in the vSphere Web Client under Administration->Single Sign-On->Configuration->Password Policy as shown in the screenshot below. For those wanting to automate this configuration, there is currently not an SSO Admin API, but there are some options, have a look at this blog post here.

Active Directory Users

If you are logging in as an Active Directory user, the password expiry notification by default is 30 days but the actual password expiry will obviously depend on your Active Directory system. If you want to change the expiry notification in case your expiry is not 30 days or you wish to notify sooner or later, this is actually controlled by the vSphere Web and H5 Client.

“Shockwave Flash has crashed” workaround for vSphere Web (Flash) Client

10/15/2017 by William Lam 80 Comments

On Saturday, I started to notice that logins to the vSphere Web (Flex) Client stopped working with Google Chrome. Upon a successful logon, it would immediately crash with "Shockwave Flash has crashed" message. I had seen this message plenty of times in the past and usually restarting Chrome would resolve the problem but this time it looked to be persistent even after a system reboot.

I took to Twitter to see if I was the only one hitting this issue since I was not able to find anything on the web and literally in minutes, I had several dozen replies with folks experiencing the same issue which apparently started several days ago but like most, including myself, thought it was an isolated event.

I thought it was just me, but apparently other folks reporting Flash crashing immediately w/Flash Web Client on latest Chrome. Anyone else? pic.twitter.com/8RWbyPGLG4

After a bit of back/fourth and a few other folks chiming in, it looks like Google actually went and published a newer version of Flash (27.0.0.170) with latest Chrome (61.0.3163.100) update. This newer Flash version is not even available for download and the current version as listed on Adobe's website should be 27.0.0.159. This issue not only affects VMware products that uses Flash but any website that has Flash content and I had also noticed few others sharing frustrations on Twitter for other flash-based websites.

~~Luckily, one workaround that I had found which others have also confirmed is to switch to Firefox which currently does not have this issue~~ Its also been reported that latest updates from Firefox is also distributing the latest Flash which causes the exact same issue. Like most, Chrome is my default browser and it was annoying that I had to switch to another browser but that was the only way I could access the content I needed. Earlier this evening, I was looking at the VMware Reddit Channel and noticed a thread had popped up regarding this exact issue and it looks like more and more folks are now noticing.

VMworld Hackathon vSphere Client Login UI Theme

09/27/2017 by William Lam 7 Comments

For those of you who attended this years VMworld Hackathon (US/Europe), you may have noticed something different when logging into the vSphere Web/H5 Client? In case you missed it or could not attend, here is a GIF demonstrating what you would have saw:

via GIPHY

No, the VMworld Hackathon environment was not hacked 😉 but instead I had built a very special VMworld Hackathon vSphere Client Login UI Theme for the event. I was also getting tired of looking at our boring blue login screen. Customizing the vSphere Client Login UI has been possible (though not officially supported by VMware) since vSphere 6.0 which I have written about here, here and most recently here (due to vSphere 6.5 Update 1 changes). Having received a large number of requests from folks who attended the Hackathon as well as folks who had heard or saw the customization who wish to replicate this in their own environment, I have posted the instructions below.

This slick customization would not have been possible without the help from Timo Sugliani (thanks dude!) who was the one that made me aware of the two of the creatives that then gave me the idea to combine them into a vSphere Client Login UI Theme. The first is V for Vendetta image which can be found here and the second is super slick interactive Bootstrap animation which can be found here. Lastly, I added my own touch by using a Mr. Robot font from this site here which goes really well with the overall theme.
