====== Estació de treball HP xw4400 per l'Avance III 400sb - Actualització al maig de 2017 ======

Actualització de l'estació de treball [[informatica:hp_xw4400_400sb | HP xw4400 de l'espectròmetre Bruker AvanceIII 400sb]].

===== Instal·lació de Debian GNU/Linux =====

La distribució de GNU/Linux que s'instal·la és la **Debian version 8.8.0,** released on  May 6th, 2017, codenamed jessie, AMD64 architecture,
  * [[https://www.debian.org/releases/stable/ | Debian “jessie” Release Information]]
    * [[https://www.debian.org/ports/amd64/ | AMD64 Port]]
    * [[https://www.debian.org/releases/stable/debian-installer/ | Installing Debian 8.8]]
  * [[https://www.debian.org/releases/stable/releasenotes | Debian 8 -- Release Notes]]

==== Configuració inicial ====

  * Language: English
  * Country: Spain
  * Locale: en_US.UTF-8
  * Keymap: Spanish
  * Host name: cie-55-31  (configuració manual)
  * Domain name: uab.es  (configuració manual)
  * User name:
    * sermnadmin  (SeRMN-UAB Staff)
    * sermnuab  (SeRMN-UAB Users) :info: es creará més un cop completada la instal·lació
  * Time zone: Madrid

==== Partició del disc ====

Faig servir l'opció "Whole disk using LVM" que crea les següents particions al disc:

FIXME   esquema de particions: boot + LVM

<file>
LVM VG cie-55-31-vg, LV home as ext4
LVM VG cie-55-31-vg, LV root as ext4
LVM VG cie-55-31-vg, LV swap_1 as swap
LVM VG cie-55-31-vg, LV tmp as ext4
LVM VG cie-55-31-vg, LV var as ext4
partition #1 of SCSI3 (0,0,0) (sda) as ext2
</file>

amb la configuració del LVM:

FIXME

<file>
Physical volume: /dev/sda3
Volume groups:   cie-55-31-vg
Logical volumes: home, root, swap_1, tmp, var
</file>

<WRAP important>
Un cop finalitzada la instal·lació, caldrà
  * ajustar la mida dels volums lògics; i
  * crear un volum lògic addicional ///opt//
</WRAP>


==== Instal·lació i configuració inicial ====

=== Instal·lació bàsica de programes ===

Les //col·leccions// de programes a instal·lar seleccionades són:
  * Standard System
  * Desktop Environment
    * Gnome
  * SSH Server
  * Web Server
  * ... FIXME comprovar ''tasksel''

La resta de programes que poguessin ser necessaris, s'instal·laran més endavant.

=== GRUB Boot Loader ===

GRUB Boot Loader s'instal·la al MBR.

=== Reiniciar per primer cop ===

Un cop s'han instal·lat tots els paquets, reinicio l'ordinador i entro a la sessió de GNU/Debian Jessie.

==== Simplificació de l'escriptori ====

<WRAP important>
Explicar la configuració final de l'escriptor, Gnome classic? per més informació consultar:
  * [[http://www.linuxquestions.org/questions/debian-26/how-can-i-enable-gnome-classic-in-jessie-4175543759/]]
  * [[https://unix.stackexchange.com/questions/199932/different-look-and-feel-for-gnome-classic-in-debian-7-and-debian-8]]
  * ...
</WRAP>

Simplifico l'escriptori:
  * Elimino el panel inferior. Abans de fer-ho, moc els applets //Window List// i //Workspace Switcher// al panel superior.
  * Elimino els applets //Notification Area// i //Window Selector// al panel superior, el primer perquè no vull que els usuaris enredin les connexions a la xarxa, i el segon perquè és redundant amb el //Window List//.
  * Al //Workspace Switcher// redueixo el nombre d'escriptoris a 2. Els usuaris de MS-Windows no coneixen el concepte d'escriptoris i tenen tendència a perdre's.
  * Canvio la configuració del //Workpsace Switcher//
    * Show windows from all workspaces
    * Group windows when space is limited
    * Restore to native workspace (les finestres minimitzades s'obren a l'escriptori on es van tancar)
  * Afegeixo els applets //Lock Screen Button// per bloquejar la pantalla, i //Log Out Button// per sortir de la sessió o per canviar a un altre usuari.

Edito el menú per amagar les aplicacions que no vull que vegin els usuaris (jocs i altres entreteniments). Més endavant miraré d'esbrinar cóm es poden desinstal·lar algunes d'aquestes aplicacions innecessàries. Entre altres:
  * L'usuari "normal" no hauria de veure el menú //System | Administration//
  * L'usuari "normal" no hauria de veure moltes de les opcions disponibles al menú //System | Preferences //
  * ...

  * :ok: meld
  * :ok: cu (command used to call up another system and act as a dial in terminal. Part of UUCP but individually packaged)


Elimino els paquets o programes:
  * :ok: telnet
  * ...

Elimino els següents metapackages per poder eliminar altres paquets o programes que depenen d'ells sense haver de desinstal·lar altres paquets que sí que m'interessen,

Comprovo que les targetes estiguin definides al fitxer ///etc/udev/rules.d/70-persistent-net.rules// per tal verificar que l'assignació de les targetes al sistema operatiu sigui estàtica i no hi hagi cap possibilitat de que canviï si es reinicia l'ordinador, de forma que la targeta a la placa base sigui sempre //eth1// i correspongui a la connexió a la consola (IPSO), i que la targeta addicional sigui sempre //eth0// i es faci servir per la connexió a la xarxa local (LAN).

Alhora, la targeta de la xarxa UAB (eth0) és configura de forma estàtica per evitar que la caiguda de la xarxa afecti el funcionament de l'espectròmetre, i els paràmetres de configuració són,
  * Hostname: cie-55-31
  * Domain: uab.es
  * IP address: 158.109.55.31
  * Broadcast: 158.109.63.255
  * Netmask: 255.255.240.0
  * DNS:

    * search uab.es
    * nameserver 158.109.0.9
    * nameserver 158.109.254.130
    * nameserver 158.109.0.1

El dispositiu //eth1// també caldrà configurar-ho de forma estàtica amb els paràmetres de connexió emprats actualment per la connexió de l'estació de treball a la consola.


==== Paquets i programes de Debian ====

<WRAP todo>
Cal decidir si es manté la configuració a través del programa //network-manager// o si es desinstal·la i es fa la configuració manual.
</WRAP>

Com que la configuració de la xarxa és estàtica, per evitar problemes elimino,
  * :fail: network-manager i :fail: network-manager-gnome, i
  * :fail: isc-dhcp i :fail: isc-dhpc-common,
i instal·lo
  * :fail: net-tools, i
  * :fail: ifupdown-extra, que alhora arrossega els paquets
    * ethtools, i
    * iputils-arping
  * :fail: wireshark

===== Altres millores a Debian =====

==== Devil's pie ====

  * [[http://www.burtonini.com/blog/computers/devilspie | Devil's Pie]] is a window-matching utility, inspired by Sawfish's "Matched Windows" option and the lack of the functionality in Metacity. Metacity lacking window matching is not a bad thing — Metacity is a lean window manager, and window matching does not have to be a window manager task. Devil's Pie can be configured to detect windows as they are created, and match the window to a set of rules. If the window matches the rules, it can perform a series of actions on that window. For example, I can make all windows created by X-Chat appear on all workspaces, and the main Gkrellm1 window does not appear in the pager or task list.
  * [[https://help.ubuntu.com/community/Devilspie | Devilspie]] is a non-gui utility that lets you make applications start in specified workplaces, in specified sizes and placements, minimized or maximized and much more based on simple config files.
  * [[http://code.google.com/p/gdevilspie/ | GDevilspie]] is a user friendly interface to the devilspie window matching daemon, to create rules easily.

Per algun motiu, aquest procediment és molt lent. Després de provar diverses recomanacions trobades a Internet sense obtenir una millora substancial a la velocitat amb què es copien les dades, decideixo deixar-ho per més endavant i provar amb el disc anterior a aquest.

Serviria de res canvia la placa de control? [[http://www.hdd-parts.com/13082508.html]]

==== Disc dur anterior ====

Com que vaig guardar el disc anterior al disc que ha fallat ara, provo a muntar-ho i a recuperar els fitxers de configuració del TopSpin i els fitxers de dades que conté.

Comprovo que es pugui llegir la taula de particions del disc

<file>

/dev/sdb4       3076   19456   16381  131580382+  83  Linux
</file>

i resulta que l'ordinador reconeix i munta automàticament les particions //sdb1// (BOOT), //sdb2// (ROOT & HOME), i //sdb4// (OPT), de forma que puc copiar el seu contingut amb la comanda ''rsync''. Les còpies es guarden provisionalment a les carpetes:

  * /home/sermnuab/Documents/old-old-hdd-recovery/sdb2-old-old-hdd-root_and_home
  * /home/sermnuab/Documents/old-old-hdd-recovery/sdb4-old-old-hdd-opt

i inclouen els directoris:

  * /etc  (71 MB)
  * /home  (147 MB)
  * /usr/local  (3.1 MB)
  * /opt/topspin/data, conf, exp, nmr_backup, i prog/au  (871 MB)

  * /opt/BASH  (451 MB)
  * /opt/sermn-uab  (ca 85 GB)  **:warn: conté les dades de rmn**

Aquest és el resum del procés de còpia de les dades de rmn,

===== Canvis a les particions =====

<WRAP todo 100%>
Cal estudiar la conveniència de moure la carpeta ///opt// a una partició separada.
</WRAP>

===== Bloqueig dels ports USB =====

Per evitar que els usuaris facin ús dels ports USB per connectar pendrives o discos externs, o del lector de CD/DVD, edito el fitxer ///etc/group// i els bloquejo l'accés eliminant l'usuari //sermnuab// dels grups //cdrom// i //plugdev//.

===== Impressora en PDF =====

Instal·lo el paquet //printer-driver-cups-pdf// per crear una impressora virtual en fitxers PDF. Això fa que s'instal·li el gestor d'impressió [[https://www.cups.org/ | CUPS]] i que a la llista d'impressores surtin les que troba a la xarxa. Per eliminar-les desactivo el servei de descoberta d'impressores:

i les impressores de xarxa despareixen i només queda la impressora virtual local.
