      @julio When you say it’s not working, does that mean you see an error somewhere or it just doesn’t seem to change the hostname?

      I would start by booting up Ubuntu after the deploy and check what you see in /etc/hostname. Is it the correct hostname that means the script did execute correctly but it might not be enough of a change for Ubuntu to accept this new hostname. If it’s not changed than you should start looking at the script again and add more statements for debugging, e.g.

      #!/bin/bash
      echo "Hello, this is my postdownload script, press ENTER to proceed"
      read
      ##détection de l’OS, 50 pour les Linux
      if [[ “$osid” == “50” ]];then
      echo "OK, osid is 50/Linux"
      ...
      

      nano fog.postdownload
      .${postdownpath}renamehost.sh

      Be careful here. You need to have a space between the dot and the dollar character for this to work!!

      . ${postdownpath}renamehost.sh
      

      One important thing is that the script needs to have the right line endings. So if you created that script using Windows notepad it will not work. Seems like you used nano but I just want to make sure!

      Web GUI issue? Please check apache error (debian/ubuntu: /var/log/apache2/error.log, centos/fedora/rhel: /var/log/httpd/error_log) and php-fpm log (/var/log/php*-fpm.log)

          @julio Looking at the script again I see an issue with the mount command. Should be mount /dev/sda1 /ext (space in between!)

          Web GUI issue? Please check apache error (debian/ubuntu: /var/log/apache2/error.log, centos/fedora/rhel: /var/log/httpd/error_log) and php-fpm log (/var/log/php*-fpm.log)

            @julio OK explaining this may be a little hard because of the language differences but lets try.

            I have examples of postdownload scripts for Windows. The concept is very similar for linux. The logic and flow have already been thought out you just need to translate for linux. You are doing a few steps wrong. I will follow on in the next post after I explain my thought here

            https://forums.fogproject.org/topic/11126/using-fog-postinstall-scripts-for-windows-driver-injection-2017-ed

            If you have windows computers and want to install hardware specific drivers then you need all of the scripts in that post. If you only have linux computers then the only base script you need is fog.custominstall

            The beginning script looks like this

            #!/bin/bash
            . /usr/share/fog/lib/funcs.sh
            [[ -z $postdownpath ]] && postdownpath="/images/postdownloadscripts/"
            case $osid in
                5|6|7|9)
                    clear
                    [[ ! -d /ntfs ]] && mkdir -p /ntfs
                    getHardDisk
                    if [[ -z $hd ]]; then
                        handleError "Could not find hdd to use"
                    fi
                    getPartitions $hd
                    for part in $parts; do
                        umount /ntfs >/dev/null 2>&1
                        fsTypeSetting "$part"
                        case $fstype in
                            ntfs)
                                dots "Testing partition $part"
                                ntfs-3g -o force,rw $part /ntfs
                                ntfsstatus="$?"
                                if [[ ! $ntfsstatus -eq 0 ]]; then
                                    echo "Skipped"
                                    continue
                                fi
                                if [[ ! -d /ntfs/windows && ! -d /ntfs/Windows && ! -d /ntfs/WINDOWS ]]; then
                                    echo "Not found"
                                    umount /ntfs >/dev/null 2>&1
                                    continue
                                fi
                                echo "Success"
                                break
                                ;;
                            *)
                                echo " * Partition $part not NTFS filesystem"
                                ;;
                        esac
                    done
                    if [[ ! $ntfsstatus -eq 0 ]]; then
                        echo "Failed"
                        debugPause
                        handleError "Failed to mount $part ($0)\n    Args: $*"
                    fi
                    echo "Done"
                    debugPause
                    . ${postdownpath}fog.copydrivers
                    # . ${postdownpath}fog.updateunattend
                    umount /ntfs
                    ;;
                *)
                    echo "Non-Windows Deployment"
                    debugPause
                    return
                    ;;
            esac
            

            If you can read program code you can see it checks to see if $osid is a ms windows type. The it uses some fog built in function to get the hard drive name, then get the partitions on the hard drive. It loops through the partitions checking to see if there is a directory called windows on that partition. We are using that to find the C drive on windows computer. Once we find the windows directory then we call the copy drivers script. At the end then we unmount the /ntfs directory and exit

            In your case you can use the same logic but for $osid of 50. Then loop through the partitions looking for the /etc directory on the mounted share of /ntfs. The programming flow for windows is very close to the programming flow I can see for linux.

            Please help us build the FOG community with everyone involved. It's not just about coding - way more we need people to test things, update documentation and most importantly work on uniting the community of people enjoying and working on FOG!

              Yes I saw that too.

                @george1421 salut george, oui j’utilise uniquement des ordinateurs linux et je voulais savoir j’utlise le script que tu viens de m’envoyer et comment je pourrais modifier cela à mon besion.

                par exemple je vois partition ntfs cà c’est windows pour linux je remplace avec ext4 ou ext. et le osid 50 mais là je vois osid in 5/6/9 etc.

                  Understand I did not test this code at all. This code may be more complex than you need if only you set the hostname. The script you have will work if you fix what Sebastian posted about your mount command. I just wanted to show you that you can make the core more responsive if your root partition is not always /dev/sda1. In some cases like UEFI disk format /dev/sda1 is the UEFI boot partition and not the OS root partition. Your code would fail if that was the case. Or if your hard drive is a NVMe type then /dev/sda (points to sata) would be wrong and the script would fail because nvme disk have a different partition structure.

                  Please help us build the FOG community with everyone involved. It's not just about coding - way more we need people to test things, update documentation and most importantly work on uniting the community of people enjoying and working on FOG!

                          No works the same. I was just warning if you use real hardware that it could change the way your script runs because hardware changes.

                          Please help us build the FOG community with everyone involved. It's not just about coding - way more we need people to test things, update documentation and most importantly work on uniting the community of people enjoying and working on FOG!

                              @julio I will give you a hint to maybe help you with your scripting.

                              FOG has a special mode you can use to debug your programs right on the target computer. So do the following.

                              1. Register your VM with fog (if you have not done so already)
                              2. Schedule a new deployment task, but before you press the Schedule Task button, enable the Debug checkbox, then schedule the task.
                              3. PXE boot the target computer.
                              4. After several screens of text, you can clear by pressing the ENTER key. You will land on the FOS LINUX command prompt.

                              Now run lsblk to find your hard drive. See if you can find from lsblk your root partition.

                              Now manually run

                              mkdir -p /ntfs
                              mount /dev/sdaX /ntfs
                              

                              Just as a test run the echo command the variable ${hostname} will not be set yet so you can’t use it here. But you can find out the right location and partition to use. You will not see all of the loop devices that ubuntu creates so it will be clear what partitions you want.

                              Please help us build the FOG community with everyone involved. It's not just about coding - way more we need people to test things, update documentation and most importantly work on uniting the community of people enjoying and working on FOG!

                                This is why I suggested to test your program using FOS Linux in debug mode. No chance to break your FOG server.

                                    @julio When you added the echo "OK, osid is 50/Linux" into your script, did you see that message on the console??

                                    You might want to add the mentioned read command as well so it waits for your input…

                                    Web GUI issue? Please check apache error (debian/ubuntu: /var/log/apache2/error.log, centos/fedora/rhel: /var/log/httpd/error_log) and php-fpm log (/var/log/php*-fpm.log)

                                    Please support FOG if you like it: https://wiki.fogproject.org/wiki/index.php/Support_FOG

                                      @sebastian-roth salut roth. non je ne vois rien sur la console de mon serveur fog apparement le script ne fonctionne pas. je veux bien savoir.
                                      comment verifier que le script est bien fonctionnel???
                                      j’ai bien donner les droits d’execution à savoir chmod +x renamehost.sh
