TigetVNC Setup

I set up the FreeUPA Client to have a graphical environment (GNOME in this case):
```
sudo dnf group install -y "Server with GUI"
```
I set the default target into graphical mode:
```
systemctl set-default graphical
```
I installed the tigervnc package:
```
sudo dnf install -y tigervnc-server
```

For the service, I set the display number as 3:

sudo cp /usr/lib/systemd/system/vncserver@.service /etc/systemd/system/vncserver@:3.service

Under vncserver.users I added my two FreeIPA Server users and assigned each of them to display 3:
```
cat << "EOF" | sudo tee -a /etc/tigervnc/vncserver.users
:3=root
EOF
```
I set the vncpasswd:
```
vncpasswd
```
Selected n at the prompt for view-only password.
Taking user test-no-1 as an example, I ran the following configuration:
I set the gnome-session to be the current session:
```
echo gnome-session > /root/.session
```
I generated the vnc directory:
```
mkdir /root/.vnc
```

I created the vnc configuration file:

cat << "EOF" | tee -a /root/.vnc/config
session=gnome
securitytypes=vncauth,tlsvnc
geometry=1920x1080
EOF

Then as root I started the vncserver:

sudo systemctl enable --now vncserver@:3.service

I added the appropriate firewall rules:

sudo firewall-cmd --permanent --add-service=vnc-server
sudo firewall-cmd --permanent --add-port=5902/tcp
sudo firewall-cmd --reload
