OK I decided to write this up after unsuccessfully being able to find all the required info I needed in one place. In this setup we will be using Ubuntu Server 22.04.2 LTS as the OS. I have this running on a home lab ESXi server 8, on a HP Compaq Pro 6300 SFF CPU = Intel Core i7-3770 Installed Memory 16 GB I have some 10K SAS drives installed for the VM's If you have not already, navigate to  Get Ubuntu Server | Download | Ubuntu and download the 22.04.2 LTS ISO Next Lets create our VM that we are going to run this in. *Note Im using ESXi however you can probably do this in Workstation, Fusion, VirtualBox etc The main things to note on the VM creation. Set Ubuntu 64 bit as the guest OS Set your CPU relevant to the physicals CPU, I will be starting with 4 VCPU Set your Memory to as much as you can tolerate, I will be using 12 Disk Space - we are creating a 100G swap file, and the rest of the file can take up some room , so more is better if you can afford it Dont forget to add the U

Red Hat Enterprise Linux as a Horizon View Instant Clone Part 3

-
Welcome to part 3 of deploying Red Had Enterprise Linux as Horizon View Instant Clones.

In this section we will go through customizing RHEL and installing the Horizon Agent.
At this point you should have already created the VM in part 1, and installed RHEL in part 2, go ahead and power on the VM and open a console to the VM (I prefer to use VMware workstation , however a browser is just fine)


Once we have the VM on and we are consoled into the VM we are presented with a login screen.
-Note that this shows the user we created during the install, It is optional but we will remove this from our linked clones as we dont want every one logging into the system to see this.


Once Logged in you are greeted with the GNOME welcome screen. This would be helpfull if your users were using persistent desktops, however we don't want to see this every time a user logs in so we will disable this as well.


Go ahead an open up terminal , and run the following to remove the GNOME welcome screen

sudo rm /etc/xdg/autostart/gnome-inital-setup-first-login.desktop





Typing sudo in front of everything, so go ahead and make your self root

sudo su



OK now we are root. Next we are going to remove the user list from the login screen, open gdm for editing by running the following:

vi /etc/dconf/profile/gdm

Enter the following information :

user-db:user
system-db:gdm
file-db:/usr/share/gdm/greeter-dconf-defaults 


Save the file.
Now edit the login screen settings
vi /etc/dconf/db/gdm.d/00-login-screen


Update the file with the following

[org/gnome/login-screen]
disable-user-list=true






write and close the file

Lastly run dconf

dconf update





Now that the login screen is fixed, lets check the network. runing an ifconfig -a shows we have the virbr0 and virbr0-nic.


 In some testing I have had issue with the View agent trying to use this adapter instead of the correct one. Since I have no applications that use this, I am disabling it all together.

To disable the nic and service run the following:

/bin/systemctl stop libvirtd.service

/bin/systemctl disable libvirtd.service


go ahead and reboot the VM.


Once the VM reboots you should no longer see any users listed


And once you login you can check that the additional nics are gone:


We are now ready to install the Horizon Agent!
Download the agent, and copy or move it to the /tmp/ folder


untar the agent

tar -xzvf VMware-horizonagent-linux-x86_64-7.6.0-9857537.tar.gz



At this point you can choose your install options, the basic is ./install_viewagent.sh -A
I have added the -f for fips, and -U for USB Redirection.



Once the install is done it will look like this

Go ahead and reboot the VM, and log back in.

Once you are logged back in, open a terminal.

We need to integrate the VM into Active Directory. This requires us to download bis-open, and join the VM to the domain.


sudo su

wget https://github.com/BeyondTrust/pbis-open/releases/download/8.7.0/pbis-open-8.7.0.478.linux.x86_64.rpm.sh

chmod 777 pbis-open-8.7.0.478.linux.x86_64.rpm.sh

./pbis-open-8.7.0.478.linux.x86_64.rpm.sh


once pbis-open installs, we will join the VM to the domain.
rune the following, change the DOMAIN.COM to your dns domain , and DOMAIN to your net-bios domain

/opt/pbis/bin/domainjoin-cli join DOMAIN.COM administrator
/opt/pbis/bin/config UserDomainPrefix DOMAIN
/opt/pbis/bin/config AssumeDefaultDomain true
/opt/pbis/bin/config LoginShellTemplate /bin/bash
/opt/pbis/bin/config HomeDirTemplate %H/%U

once you have run all the commands with out error, reboot the VM.
Once it comes up, shut it down and take a new snapshot. We are now ready to deploy the Instant clones and will go through that in part 4.

vSphere 7 - Specify a vmkernel adapter to use for NFS datastores Step By Step \ Walkthrough on a DVS

Image
 Recently I needed to setup a NFS server but needed it to specifically be on a specific vmkernel adapter. I found this KB https://kb.vmware.com/s/article/50112854 however there were some things missing so I decided to write this walkthrough incase it helps any one else. First thing , remove all NFS mounted datastores if you haven't already. I ran through this on 7.0.2 however is probably the same for other versions. Step 1: This is going to be on a DVS, so we want to go ahead and create a port group to silo off our NFS traffic. To make life easy, we will just call it NFS Static binding and elastic port allocation were the defaults so I let these there. If you are VLAN'ing your traffic modify this info here, and complete the wizard. Next put your host into Maintenance Mode We are going to add a New TCP/IP stack to the host. First check that you have not already created one in the UI by opening a browser to the ESXi host, navigate to networking > TCP/IP Stacks SSH into your ES

Horizon View 2-factor Authentication for Free! with Google Authenticator or others

So after quite a bit of work on my proof of concept google authenticator server, a colleague pointed out that LinOPT has already created this, along a whole slew of other options. So after spending a couple of nights reading and testing I figured id post a simple walk-through to get this up and running in your environment. As mentioned in the title this is a Free solution , however if you are wanting to scale this in a large organization you would most likely want to explore their support contracts , this is a good fall back when things just don't work and this also help the developers keep this type of software free for the rest of us. To start off we want to create 2 objects in Active Director. The first is just a standard user account LinOTP will use to connect to your domain. You can put these any where in your domain as we will access them directly later. In my case i create one called 'LinOTP Svc' and put it in the default Users OU. Next create a Global or
