VMworld 2018: The return of the cloud – Part 2

Vendors


The vendors at VMworld this year was what you would expect from one of the biggest conferences in tech. There was a lot of big vendors such as Dell/EMC, Lenovo, AWS, and IBM, but I really find interest in the small vendors. The up and coming technology that is the way of the future.

These are just three of the vendor’s i enjoyed seeing at VMworld 2018

Docker

You had some great vendors like Docker at the event. Containers are the way of the future and Docker is the leader in the industry. I really enjoyed chatting with them this year and I gained a lot of knowledge from the breakout sessions I went to where Docker was a topic (I don’t know if they lead those sessions or not), So much so that I really want to do a Docker for noobs video series where I video document my whole experience in learning Docker from zero to hero. But more about that later on.

Men & mice

This is a super awesome group of icelandic men/women. They specialize in DNS/DHCP/IPAM in the cloud solutions, and while it is not a new problem people have faced (As it pertains to private cloud)  there is a lot that can be said about the people at the booth, they love what they do and they are passionate about the product. That is why I love this company and the booth. They know they are the best and they let the product do the talking for them. Really impressive company and even more impressive people.

Rubrik

This company has been killing it over the last three-year. Rubrik has been Dominating the backup space at what seems like hyper-speed. Although I have never used Rubrik as a backup solution from what people have said it’s an awesome intuitive product. They sell Rubrik based on future proofing your backup and anyone I have asked has not had any complaint with them. This year at VMworld Rubrik took home best of show. Which in my opinion is well deserved. The way Rubrik cares about the community of technologists and their work to be top of the line backup earns them that spot.

VMworld 2018: The return of the cloud – Part 1


So VMworld 2018 is a wrap and i had the awesome privilege to attend this year! I would like to say first thing, if you have never been to VMWorld the networking opportunities alone is worth the price of admission. The technology you will be seeing most of the time first hand is worth the flight and hotel fee’s.

This year was full of great keynotes and some awesome vendors both large and small. So lets dive into it.

 

Keynotes


The keynotes were the usual setup, just like last year they came out on stage after a dramatic opening to the first day of vmworld, and just like last year they went hard on the usual products AWS/NSX/VSAN.  Which I cannot blame them honestly its the way of the future, and will be the biggest money maker for VMware and its partners.

Day one and two were good keynotes with the usual technical announcements nothing major that we haven’t seen in the past, but some improvements on already existing technologies. With the exception of the 64Bit ARM platforms, which is awesome in my opinion. A lot of people have waited for this announcement and I got really good feedback from people i asked who had an interest in ESXi for the ARM platform.

Day three was interesting, with an hour long round table interview with the Sanjay Poonen with multiple C level exec’s from big non relevant companies, the external stream ended for people watching online and the interview that everyone was waited for began. For some reason VMware had the last keynote end with a hour long discussion with Malala, while the noble peace prize winner is admirable and a really fantastic human being i don’t see the point of having that discussion at a tech conference. Some people i talked to loved the interview, some not so much.I was in-between, i was impressed with her but didn’t really see the point. Some people took it at a jab of the technical community for being unfair to women in the field, and VMware highlighting that.

When you bring in someone like Malala it is impressive, but her message is so direct that it felt like VMware was trying to send a message to the tech world, whether purposely or it just happen to show like that some people took it that way.

 

Part 2 Coming up.

EMC ESRSve admin password reset (VXRail Edition)

Resetting a password on a ESRS appliance is pretty straight forward. But there is a pesky error that can pop up from time to time with ESRS appliances that get deployed via the VXRail deployment.

The normal esrs admin password reset goes something like this:


ESRSapplicance:~ # cd /opt/esrs/webuimgmt-util/
ESRSapplicance:~ # ./passwordAdmin.sh

Normally this would then ask you for a new password for the admin account associated with your ESRS appliance.

But what is the error you might ask? Well it happens in lieu of asking for a new password.

“User Configuration File Missing. Please contact ESRS Support”

In order to get around this error it is a simple command you must run before starting the ./passwordadmin.sh script:


ESRSapplicance:~ # echo admin > /etc/esrsadmin.conf
ESRSapplicance:~ # cd /opt/esrs/webuimgmt-util/
ESRSapplicance:~ # ./passwordAdmin.sh

And thats it! Have fun with ESRS and let me know it this article helped you!

A General system error occurred: Connection refused

Got this error today when trying to start up a VM.

A General system error occurred: Connection refused

 

While it was annoying to see, this issue is easily resolved. At least for me.

Log into your VCSA and first check the drive space

user@VCSA:$ df -h

Confirm the none of the drives are full

Then check the status and start the vmware-vpx-workflow service

user@VCSA:$ service-control --status vmware-vpx-workflow
user@VCSA:$ service-control --start vmware-vpx-workflow

It will take a second to start the service but that should do the trick!

 

VExpert 2018

I wanted to make a short post to say thanks to the VExpert community. I have been selected as a VExpert for the second year.. it has been awesome to be apart of this awesome community.

It has been a great experience meeting a lot of new people over the past year, and lets hope 2018 is even better!

AppVol: Capture Machine boots to AppStack VMDK instead of OS

Been running to issues when provisioning Application stacks that the capture machine boots to the the AppStack VMDK instead of the OS VMDK . It is an annoying issue but a very easy fix!

  1. Shutdown the capture machine and take a snapshot.
  2. Edit the settings of the capture machine, change the primary hard drive to SCSI (0:0) under the Virtual Device Node option.
  3. Select the VM options tab > boot options > Force Bios Setup
  4. During the bios setup navigate to boot and ensure the harddrive is first in the boot order.
  5. Restart your capture VM and try to mount the appStack for provisioning.

 

 

RHEL/CentOS7 xrdp auto disconnects when logging on

So I ran into an issue this week with XRDP disconnecting from my RHEL/CentOS7 RDP connection the moment the logon process is finished. Searching around for different answers to this solution there seems to be no one way of doing it. So I decided to tell you what I did to fix the issue and hopefully help you avoid a major headache in the future.

 

I will start with the installation of XRDP and go through the changes.

  1. Install xrdp tigervnc-server on your RHEL/CentOS7 box
yum -y install xrdp tigervnc-server

2. Start xrdp service and enable at boot

systemctl enable xrdp
user@computer:$ systemctl start xrdp

3. Allow 3389 through the firewall and reload firewall

firewall-cmd --permanent --zone=public --add-port=3389/tcp 
user@computer:$ firewall-cmd --reload

4. Configure SELinux ( I did not need to perform this step)

chcon --type=bin_t /usr/bin/xrdp
user@computer:$ chcon --type=bin_t /usr/bin/xrdp-sesman

5. Edit the xrdp.ini file located at the /etc/xrdp/xrdp.ini

vi /etx/xrdp/xrdp.ini

6. Comment out the line that says “Channel_code=1” Here is a example of the .ini file after the change is made

[globals]
bitmap_cache=yes
bitmap_compression=yes
port=3389
crypt_level=high
#channel_code=1
max_bpp=24
#black=000000
#grey=d6d3ce
#dark_grey=808080
#blue=08246b
#dark_blue=08246b
#white=ffffff
#red=ff0000
#green=00ff00
#background=626c72

[xrdp1]
name=sesman-Xvnc
lib=libvnc.so
username=ask
password=ask
ip=127.0.0.1

Just a FYI also some of these commands I did not come up with and where figured out from other blogs. Which when I get permission from the owners I will post here.

That being said this is my first post into some real enterprise level Linux! If you have any tip or tricks as i go down the RHEL CentOS path let me know!
