Download a set of Debian ISO files from the Internet. I use `jigdo` for this.

Copy your downloaded ISO files to the directory where you will store them on the server. In this example, I copied the ISOs into the following directory:

/home/idtm/DebianRepository/Debian12/

Make a copy of this mount script LINK_HERE and copy it to the .bin directory in the home folder. Rename it:

mount-Debian12-64bit-DVD-repo-local.sh

Make sure the script is executable. You can run the following command:

chmod u+x mount-Debian12-64bit-DVD-repo-local.sh

Modify the mount-Debian12-64bit-DVD-repo-local.sh script as follows:

• Change references to /media to /mnt
• Set the isopath variable to point to the directory where your ISOs are stored.

Run this script using sudo and verify that it works by navigating to the /mnt folder in your file browser. You should see a folder for each of your ISOs.

In a terminal, change directory to the root directory of the web server:

cd /var/www/html

Next, create a directory called debian12:

sudo mkdir debian12

Change directory to debian12:

cd debian12

In this directory, we need to create a symbolic link to each mount point for our ISO files in /mnt.

Open a text editor and create a new document called makedirs.sh, and put the following lines in it:

#!/bin/bash
for value in {1..21}
do
  ln -s /mnt/Deb-64bit-disc_$value Deb-64bit-disc_$value
done

Replace 21 with the actual number of ISO files you are using. Save the document and exit.

Make it executable with:

sudo chmod u+x makedirs.sh

Now, run the script to create the symbolic links:

sudo ./makedirs.sh

Once the Debian repository is set up on the server, set up each client computer to Connect to a Network Drive.
