Bonjour à tous,

Je vais tenter de vous exposer mon soucis de façon claire et détaillée...

Je me suis lancé dans l'installation d'un serveur PXE (sous debian etch) pour l'installation par le réseau afin de me faciliter la tache lors d'installation de machines debian etch à la chaine.

Jusque là pas de problème, j'utilise dhcp3-server, tftpd-hpa et j'ai téléchagargé les fichiers necessaires, tout cela fonctionne parfaitement, j'arrive à faire l'installation sans soucis.

Pour encore plus de facilité, j'ai décidé de mettre en place une installation automatique au maximum, j'ai donc tenter de faire cela avec kickstart, dans un premier temps, puis preseed.

Avec kickstart j'ai généré un fichier de préconfiguration grâce à l'interface graphique proposée par le logiciel.
Avec preseed, j'ai modifié légerement le fichier d'exemple, simplement dans le but de tester le bon fonctionnement de cette méthode...

Malheureusement dans les 2 cas, cela ne fonctionne pas, l'installation de debian etch se fait comme si je n'avais pas spécifié de fichier de préconfiguration... j'ai donc lancé un tcpdump sur la machine qui héberge mes scripts KS.cfg et preseed.cfg afin de voir si une requête pour demander le fichier est envoyée... et je ne constate rien du tout de ce style... Le boot ignore completement ma demande de prendre en compte le fichier de préconfiguration.

J'ai tenté pas mal de choses dans le fichier default de pxelinux.cfg mais voici celui qui est le plus simple et qui me parait cohérent :

Code:
DISPLAY debian/etch/boot-screens/boot.txt

F1 debian/etch/boot-screens/f1.txt
F2 debian/etch/boot-screens/f2.txt
F3 debian/etch/boot-screens/f3.txt

        APPEND initrd=debian/etch/initrd.gz ks=http://10.0.27.240/debian/ks.cfg --

Dans le /var/log/syslog de la machine en cours d'installation, j'ai bien la ligne APPEND qui apparait et elle ne me retourne aucune erreur.

Voici aussi les fichiers ks.cfg et preseed.cfg :

### Network configuration
# netcfg will choose an interface that has link if possible. This makes it
# skip displaying a list if there is more than one interface.
d-i netcfg/choose_interface select auto

# To pick a particular interface instead:
#d-i netcfg/choose_interface select eth1

# If you have a slow dhcp server and the installer times out waiting for
# it, this might be useful.
#d-i netcfg/dhcp_timeout string 60

# If you prefer to configure the network manually, uncomment this line and
# the static network configuration below.
#d-i netcfg/disable_dhcp boolean true

# If you want the preconfiguration file to work on systems both with and
# without a dhcp server, uncomment these lines and the static network
# configuration below.
#d-i netcfg/dhcp_failed note
#d-i netcfg/dhcp_options select Configure network manually

# Static network configuration.

### Partitioning
# If the system has free space you can choose to only partition that space.
# Note: this must be preseeded with a localized (translated) value.
#d-i partman-auto/init_automatically_partition \
#      select Guided - use the largest continuous free space

# Alternatively, you can specify a disk to partition. The device name
# can be given in either devfs or traditional non-devfs format.
# For example, to use the first disk:
d-i partman-auto/disk string /dev/discs/disc0/disc
# In addition, you'll need to specify the method to use.
# The presently available methods are: "regular", "lvm" and "crypto"
d-i partman-auto/method string lvm

# If one of the disks that are going to be automatically partitioned
# contains an old LVM configuration, the user will normally receive a
# warning. This can be preseeded away...
d-i partman-auto/purge_lvm_from_device boolean true
# And the same goes for the confirmation to write the lvm partitions.
d-i partman-lvm/confirm boolean true

# You can choose from any of the predefined partitioning recipes.
# Note: this must be preseeded with a localized (translated) value.
d-i partman-auto/choose_recipe \
       select All files in one partition (recommended for new users)
#d-i partman-auto/choose_recipe \
#       select Separate /home partition
#d-i partman-auto/choose_recipe \
#       select Separate /home, /usr, /var, and /tmp partitions

# Or provide a recipe of your own...
# The recipe format is documented in the file devel/partman-auto-recipe.txt.
# If you have a way to get a recipe file into the d-i environment, you can
# just point at it.
#d-i partman-auto/expert_recipe_file string /hd-media/recipe

# If not, you can put an entire recipe into the preconfiguration file in one
# (logical) line. This example creates a small /boot partition, suitable
# swap, and uses the rest of the space for the root partition:
#d-i partman-auto/expert_recipe string                         \
#      boot-root ::                                            \
#              40 50 100 ext3                                  \
#                      $primary{ } $bootable{ }                \
#                      method{ format } format{ }              \
#                      use_filesystem{ } filesystem{ ext3 }    \
#                      mountpoint{ /boot }                     \
#              .                                               \
#              500 10000 1000000000 ext3                       \
#                      method{ format } format{ }              \
#                      use_filesystem{ } filesystem{ ext3 }    \
#                      mountpoint{ / }                         \
#              .                                               \

#                      method{ swap } format{ }                \
#              .

# This makes partman automatically partition without confirmation.
d-i partman/confirm_write_new_label boolean true
d-i partman/choose_partition \
       select Finish partitioning and write changes to disk
d-i partman/confirm boolean true

### Clock and time zone setup
# Controls whether or not the hardware clock is set to UTC.
d-i clock-setup/utc boolean true

# You may set this to any valid setting for $TZ; see the contents of
# /usr/share/zoneinfo/ for valid values.
d-i time/zone string US/Eastern

### Apt setup
# You can choose to install non-free and contrib software.
#d-i apt-setup/non-free boolean true
#d-i apt-setup/contrib boolean true
# Uncomment this if you don't want to use a network mirror.
#d-i apt-setup/use_mirror boolean false
# Uncomment this to avoid adding security sources, or
# add a hostname to use a different server than security.debian.org.
#d-i apt-setup/security_host string

# Additional repositories, local[0-9] available
#d-i apt-setup/local0/repository string \
#       deb [local.server] stable main
#d-i apt-setup/local0/comment string local server
# Enable deb-src lines
#d-i apt-setup/local0/source boolean true
# URL to the public key of the local repository; you must provide a key or
# apt will complain about the unauthenticated repository and so the
# sources.list line will be left commented out
#d-i apt-setup/local0/key string [local.server]

# By default the installer requires that repositories be authenticated
# using a known gpg key. This setting can be used to disable that
# authentication. Warning: Insecure, not recommended.
#d-i debian-installer/allow_unauthenticated string true

### Account setup
# Skip creation of a root account (normal user account will be able to
# use sudo).
#d-i passwd/root-login boolean false
# Alternatively, to skip creation of a normal user account.
#d-i passwd/make-user boolean false

# Root password, either in clear text
#d-i passwd/root-password password r00tme
#d-i passwd/root-password-again password r00tme
# or encrypted using an MD5 hash.
#d-i passwd/root-password-crypted password [MD5 hash]

# To create a normal user account.
#d-i passwd/user-fullname string Debian User
#d-i passwd/username string debian
# Normal user's password, either in clear text
#d-i passwd/user-password password insecure
#d-i passwd/user-password-again password insecure
# or encrypted using an MD5 hash.
#d-i passwd/user-password-crypted password [MD5 hash]

### Base system installation
# Select the initramfs generator used to generate the initrd for 2.6 kernels.
#d-i base-installer/kernel/linux/initramfs-generators string yaird

### Boot loader installation
# Grub is the default boot loader (for x86). If you want lilo installed
# instead, uncomment this:
#d-i grub-installer/skip boolean true

# This is fairly safe to set, it makes grub install automatically to the MBR
# if no other operating system is detected on the machine.
d-i grub-installer/only_debian boolean true

# This one makes grub-installer install to the MBR if it also finds some other
# OS, which is less safe as it might not be able to boot that other OS.
d-i grub-installer/with_other_os boolean true

# Alternatively, if you want to install to a location other than the mbr,
# uncomment and edit these lines:
#d-i grub-installer/only_debian boolean false
#d-i grub-installer/with_other_os boolean false
#d-i grub-installer/bootdev  string (hd0,0)
# To install grub to multiple disks:
#d-i grub-installer/bootdev  string (hd0,0) (hd1,0) (hd2,0)

### Package selection
tasksel tasksel/first multiselect standard, desktop
#tasksel tasksel/first multiselect standard, web-server
#tasksel tasksel/first multiselect standard, kde-desktop

# Individual additional packages to install
#d-i pkgsel/include string openssh-server build-essential

# Some versions of the installer can report back on what software you have
# installed, and what software you use. The default is not to report back,
# but sending reports helps the project determine what software is most
# popular and include it on CDs.
#popularity-contest popularity-contest/participate boolean false

### Finishing up the first stage install
# Avoid that last message about the install being complete.
d-i finish-install/reboot_in_progress note

# This will prevent the installer from ejecting the CD during the reboot,
# which is useful in some situations.
#d-i cdrom-detect/eject boolean false

### X configuration
# X can detect the right driver for some cards, but if you're preseeding,
# you override whatever it chooses. Still, vesa will work most places.
#xserver-xorg xserver-xorg/config/device/driver select vesa

# A caveat with mouse autodetection is that if it fails, X will retry it
# over and over. So if it's preseeded to be done, there is a possibility of
# an infinite loop if the mouse is not autodetected.
#xserver-xorg xserver-xorg/autodetect_mouse boolean true

# Monitor autodetection is recommended.
xserver-xorg xserver-xorg/autodetect_monitor boolean true
# Uncomment if you have an LCD display.
#xserver-xorg xserver-xorg/config/monitor/lcd boolean true
# X has three configuration paths for the monitor. Here's how to preseed
# the "medium" path, which is always available. The "simple" path may not
# be available, and the "advanced" path asks too many questions.
xserver-xorg xserver-xorg/config/monitor/selection-method \
       select medium
xserver-xorg xserver-xorg/config/monitor/mode-list \
       select 1024x768 @ 60 Hz

### Preseeding other packages
# Depending on what software you choose to install, or if things go wrong
# during the installation process, it's possible that other questions may
# be asked. You can preseed those too, of course. To get a list of every
# possible question that could be asked during an install, do an
# installation, and then run these commands:
#   debconf-get-selections --installer > file
#   debconf-get-selections >> file


#### Advanced options
### Running custom commands during the installation
# d-i preseeding is inherently not secure. Nothing in the installer checks
# for attempts at buffer overflows or other exploits of the values of a
# preconfiguration file like this one. Only use preconfiguration files from
# trusted locations! To drive that home, and because it's generally useful,
# here's a way to run any shell command you'd like inside the installer,
# automatically.

# This first command is run as early as possible, just after
# preseeding is read.
#d-i preseed/early_command string anna-install some-udeb

# This command is run just before the install finishes, but when there is
# still a usable /target directory. You can chroot to /target and use it
# directly, or use the apt-install and in-target commands to easily install
# packages and run commands in the target system.
#d-i preseed/late_command string apt-install zsh; in-target chsh -s /bin/zsh
