### download_debian.sh

||
The script will provide netboot installers for all Debian (>=oldStable) for both **i386** and **amd64** :
|
||
* Store the files to **/var/lib/tftpboot** (default).
|
||
* Download Debian Linux kernel and initrd files for all Debian distributions (Stable : **Stretch**; Testing : **Buster**; oldStable : **Jessie**; oldoldStable : **Wheezy**; Unstable : **Sid**) and for **i386** and **amd64** architectures.
|
||
* Offer an example menu file to use with a TFTP server (default_path/installer/debian/menu.cfg.example).
|
||
|
||
### download_ubuntu.sh
|
||
The script will provide netboot installers for the latest LTS and latest advanced Ubuntu distribution for both **i386** and **amd64** :

|
||
* Download Ubuntu Linux kernel and initrd files for the two lasts Ubuntu distributions (LTS-16.04 : **Xenial**; 15.10 : **Wily**) and for **i386** and **amd64** architectures.
|
||
* Make a symlink to access to the LTS (default_path/installer/ubuntu/lts) instead of it's codename.
|

|
||
### make_debian_initrd_with_firmware.sh

|
||
* Store temp files to **/tmp/tmp.XXXXXXXXXX** (with `mktemp`).
|
||
* Download Debian's initrd files for all Debian distributions (Stable : **Stretch**; Testing : **Buster**; oldStable : **Jessie**; oldoldStable : **Wheezy**; Unstable : **Sid**) for **amd64** architecture only.
|
||
* Download additionnals firmwares :
|
||
* **bnx2** : For Broadcom NetXtremeII network adapters.
|
||
* **linux-nonfree** : For Tigon network adapters.
|
||
* **myricom** : For Myricom Myri-10G Ethernet adapters (IBM server).
|
||
* **qlogic** : For QLogic Infiniband, SCSI, Fibre Channel/FCoE adapters.
|
||
* Extract initrd and firmwares packages to build a new initrd.
|
||
|
||
### Debian late_command
|
||
|
||
#### Description
|
||
Some useful configurations after a Debian installation :
|
||
* Smarter log management (mainly for rotation and old logs).
|
||
* Move `rsyslog` default configuration to two files (__/etc/rsyslog.conf__ and __/etc/rsyslog.d/99syslog.conf__).
|
||
* `logrotate` now rotate logs to specific directories (such as __/var/log/syslog.d__, __/var/log/mail/__,…) instead of __/var/log/__.
|
||
* Create these new directories.
|
||
* Remove some useless packages (nfs, tasksel,…).
|
||
* Permit root SSH login with password (no standard user…).
|
||
* …
|
||
|
||
Specific to Debian Jessie and older :
|
||
* Smarter rsyslog (more directories and less files in **/var/log**).
|
||
* Shorter configuration file and use more files from /etc/rsyslog.d/
|
||
* Move log files to directory :
|
||
* _kern_ logs from /var/log/kern.log to __/var/log/kernel/kernel.log__
|
||
* _user_ logs from /var/log/user.log to __/var/log/security/user.log__
|
||
* _mail_ logs from /var/log/mail.… to __/var/log/mail/mail.…__
|
||
* _daemon_ logs from /var/log/daemon.log to __/var/log/syslog/daemon.log__
|
||
* _auth_ logs from /var/log/auth.log to __/var/log/security/auth.log__
|
||
* _lpr_ logs from/var/log/lpr.log to __/var/log/lpr/lpr.log__
|
||
* _cron_ logs from /var/log/cron.log to __/var/log/cron/cron.log__
|
||
* _localX_ logs from /var/log/localX.log to __/var/log/syslog/localX.log__
|
||
* _syslog_ logs from /var/log/syslog.log to __/var/log/syslog/syslog.log__
|
||
* _authpriv_ logs from … to __/var/log/security/authpriv.log__
|
||
|
||
#### How-to use it
|
||
* First, make an archive of the script and directories :
|
||
```
|
||
cd scripts/ ;
|
||
tar czvf latecommand.tar.gz latecommand/
|
||
```
|
||
* Then, it can be use at the end of a Debian preseed file :
|
||
```
|
||
d-i preseed/late_command string in-target chsh -s /bin/zsh ; \
|
||
in-target /usr/bin/tftp ${IP.SRV.TFTP} -c get ${PATH/TO/TFTPD/ROOT}/scripts/latecommand.tar.gz /tmp/latecommand.tar.gz ; \
|
||
in-target tar xzf /tmp/latecommand.tar.gz -C /tmp/ ; \
|
||
in-target /bin/sh /tmp/latecommand/post.sh
|
||
```
|
||
|
||
### download_diag_tools.sh
|
||
- The script will download some diagnostic tools :
|
||
* memtest86 from [memtest86's official website][memtest official website].
|
||
* GParted Live from the [sourceforge's repository][gparted sourceforge] for both amd64 and i686. See the [official documentation][gparted pxe] for more informations.
|
||
- Provide an example of configuration file.
|
||
|
||
### download_clonezilla.sh
|
||
* Download PXE files for Clonezilla live from [OSDN][OSDN url]. A Sourceforge repository is also available but…; see the [Clonezilla download page][clonezilla download] for more informations.
|
||
* Download for both **amd64** and **i686**.
|
||
* Make a example configuration file.
|
||
* More informations on the [Clonezilla website][clonezilla via pxe server].
|
||
|
||
## Update
|
||
The netboot's installers, at least for Debian, need to be update **after each point realease**. Just think about it if you got any issue during any installation from PXE.
|
||
* Debian : `sudo ./scripts/download_debian.sh`
|
||
* Debian's initrd with additionnals firmwares : `sudo ./scripts/make_debian_initrd_with_firmware.sh`
|
||
* Ubuntu : `sudo ./scripts/download_ubuntu.sh`
|
||
|
||
Some tools depends of a static version in their script. So this is the list i check to got their new version :
|
||
* [Clonezilla download page][clonezilla download]
|
||
* [Gparted sourceforge's repository][gparted sourceforge]
|
||
* [Memtest86's official website][memtest official website] (quite useless, last update was ~3 years ago ^^)
