Explanation:
1. Configure Host Name
vim /etc/sysconfig/network NETWORKING=yes HOSTNAME=dtop5.dn.ws.com GATEWAY=172.28.10.1
2. Configure IP Address, Gateway and DNS
Configure the network by Network Manager:

Note: Please remember to choose two options:
Connect automatically
Available to all users
Click "Apply", save and exit, and restart your network services:
# Service network restart
3. Validate these profiles:
a) Check gateway: # vim / etc / sysconfig / network
NETWORKING=yes
HOSTNAME=dtop5.dn.ws.com
GATEWAY=172.28.10.1
b) Check Host Name: # vim /etc/hosts

c) Check DNS: # vim /etc/resolv.conf
# Generated by NetworkManager
Search dn.ws.com
Nameserver 172.28.10.1
d) Check Gateway: # vim /etc/sysconfig/network-scripts/ifcfg-eth0

Solution:
# Note: Perform the following operations by SSHing into localhost as the user "wallah"
[root@node1 ~]# ssh wallah@localhost
# Prepare the relevant mapping directories
[wallah@node1 ~]$ sudo mkdir /opt/{file,progress}
[wallah@node1 ~]$ sudo chown wallah:wallah /opt/{file,progress}
# Start the container and map directories
# :Z changes the SELinux security context of the directory to allow container access.
[wallah@node1 ~]$ podman run -d --name ascii2pdf -v /opt/file:/dir1:Z -v /opt/progress:/dir2:Z pdf
[wallah@node1 ~]$ podman ps -a
# Create systemd service file
[wallah@node1 ~]$ mkdir -p ~/.config/systemd/user
[wallah@node1 ~]$ cd ~/.config/systemd/user/
[wallah@node1 ~]$ podman generate systemd -n ascii2pdf -f --new
[wallah@node1 user]$ ll
total 4
-rw-r--r--. 1 wallah wallah 770 Dec 13 01:07 container-ascii2pdf.service
# Stop and remove the existing ascii2pdf container
[wallah@node1 ~]$ podman stop ascii2pdf
[wallah@node1 ~]$ podman rm ascii2pdf
[wallah@node1 ~]$ podman ps -a
# Enable and start the container-ascii2pdf service
[wallah@node1 ~]$ systemctl --user daemon-reload
[wallah@node1 ~]$ systemctl --user enable --now container-ascii2pdf
# Check container status
[wallah@node1 ~]$ systemctl --user status container-ascii2pdf
[wallah@node1 ~]$ podman ps
# On node1, switch to the root user to perform the following operations
# Ensure that the services for the wallah user start automatically at system boot
[root@node1 ~]# loginctl enable-linger
[root@node1 ~]# loginctl show-user wallah
# Check to ensure the container starts on boot (mandatory operation)
[root@node1 ~]# reboot
[root@node1 ~]# ssh wallah@node1
[wallah@node1 ~]# podman ps

Explanation:
Solution:
dnf install -y httpd policycoreutils-python-utils
mkdir -p /webdata
echo "RHEL10 Web Server" > /webdata/index.html
sed -i 's/^Listen 80/Listen 8080/' /etc/httpd/conf/httpd.conf
semanage port -a -t http_port_t -p tcp 8080
firewall-cmd --permanent --add-port=8080/tcp
firewall-cmd --reload
systemctl enable --now httpd
systemctl restart httpd
ss -tulpn | grep 8080
Detailed Explanation:
* Apache defaults to port 80, so Listen 8080 changes the service port.
* SELinux must allow Apache to bind to 8080, which is done with semanage port.
* firewall-cmd opens the port externally.
* RHEL 10 documents firewalld as the standard firewall management interface and SELinux port
labeling for confined services. ( Red Hat Documentation )
