Les particions sda1 i sda2 contenen la instal·lació original de Windows 7.

Les col·leccions de programes a instal·lar seleccionades són:

• Desktop Environment
• Standard System

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

GRUB Boot Loader s'instal·la al MBR.

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

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
• …

Afegeixo altres magatzems (repositories) de programes:

• deb http://backports.debian.org/debian-backports/ squeeze-backports main
• deb http://www.debian-multimedia.org/ squeeze main contrib non-free

i la signatura (debian-multimedia-keyring) del magatzem debian-multimedia, i instal·lo:

• Adobe Acrobat Reader

Afegeixo els següents paquets o programes (aquest no és un llistat exhaustiu, només inclou els dimonis i servidors de xarxa, i altres programes importants):

• ssh (openssh-server, openssh-client)
• mc (midnight commander)
• rsync
• ftp-ssl en comptes de ftp
• denyhosts
• nfs-kernel-server
• tftp-hpa
• tftpd-hpa Cal reconfigurar!
• bootparamd Cal reconfigurar!
• xinetd (en comptes del programa per defecte: openbsd-inetd)

Elimino els paquets o programes:

• 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,

• gnome
• gnome-desktop-environment
• gnome-office

Llavors desinstal·lo:

• gnome-games, gnome-games-data, gnome-games-extra-data
• simple-scan, xsane, xsane-common, i les biblioteques relacionades
• …

Substitueixo la versió lliure de Java (java-6-openjdk i paquets que en dependen) per la versió oficial (sun-java6-jdk i paquets que en depenen).

Actualment la configuració de la xarxa de la UAB la proporciona un servidor de DHCP. Per evitar que la caiguda de la xarxa afecti el funcionament de l'espectròmetre, la configuració s'haurà de canviar a estàtica. Els paràmetres 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:
  • domain uab.es
  • search uab.es
  • nameserver 158.109.0.9
  • nameserver 158.109.254.130
  • nameserver 158.109.0.1

La configuració de més amunt és l'emprada per la targeta de xarxa de la placa basse,

eth0      Link encap:Ethernet  HWaddr 3c:d9:2b:73:ea:93  
          inet addr:158.109.56.18  Bcast:158.109.63.255  Mask:255.255.240.0

          RX bytes:23348532 (22.2 MiB)  TX bytes:123310 (120.4 KiB)
          Interrupt:17 

i ha estat obtinguda del servidor de DHCP de la universitat, a l'igual que la configuració de servidors de noms,

# more resolv.conf 
# Generated by NetworkManager

search uab.es
nameserver 158.109.0.9
nameserver 158.109.254.130

La targeta de xarxa addicional també es reconeix,

eth1      Link encap:Ethernet  HWaddr 1c:7e:e5:10:90:0a  
          UP BROADCAST MULTICAST  MTU:1500  Metric:1

          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)
          Interrupt:21 Base address:0x6000 

però no té una configuració assignada. Caldrà configurar-la de forma estàtica amb els paràmetres de connexió emprats actualment per la connexió de l'estació de treball a la consola.

Com que la configuració de la xarxa és estàtica, per evitar problemes elimino,

• network-manager i network-manager-gnome, i
• isc-dhcp i isc-dhpc-common,

i instal·lo

• net-tools, i
• ifupdown-extra, que alhora arrossega els paquets
  • ethtools, i
  • iputils-arping

Per evitar que en algun moment es pugui bescanviar la configuració de les targetes de xarxa poso en pràctica les opcions esmentades a How to reorder or rename logical interface names in Linux.

Una opció seria fer servir el programa nameif (paquet net-tools) per assignar un nom de dispositiu en funció de l'adreça física de la targeta; i després emprar el nom de dispositiu assignat al fitxer de configuració etc/network/interface.

Però una consulta al fitxer etc/udev/rules.d/70-persistent-net.rules indica que l'assignació del nom de dispositiu, eth0 o eth1 feta pel programa udev és fixe, i que no hi ha perill de que canviï en reiniciar l'ordinador,

root@cie-55-31:/etc/udev/rules.d# more 70-persistent-net.rules 
# This file was automatically generated by the /lib/udev/write_net_rules
# program, run by the persistent-net-generator.rules rules file.
#
# You can modify it, as long as you keep each rule on a single
# line, and change only the value of the NAME= key.

# PCI device 0x14e4:0x1684 (tg3)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="3c:d9:2b:73:ea:93",
  ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"

  ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"

Així doncs, podem fer servir eth0 i eth1 al fitxer de configuració etc/network/interfaces sense preocupacions.

Aquesta és la configuració de xarxa provissional emprada per la instal·lació i configuració del sistema operatiu i del programa TopSpin.

S'ha de configurar (fitxer /etc/avahi/avahi-daemon.conf) per tal de restringir la difusió dels serveis disponibles a l'ordinador i, potser, la cerca de serveis a la xarxa.

Instal·lo el paquet ntp i al final del fitxer /etc/ntp.conf afegeixo els següents servidors de temps,

• server swisstime.ethz.ch
• server ntp.uab.es
• server ntp.univ-lyon1.fr

Afegeixo els programes:

• Firefox del lloc web de Mozilla

Aparentment no cal instal·lar cap driver especial ja que la targeta és suportada per GNU/Linux, però per si de cas, aquests són alguns enllaços relacionats amb aquest model de targeta:

• linux driver dge-528t a Google
• Technical Support - DGE-528T - Copper Gigabit PCI Card for PC
• DGE-528T - Copper Gigabit PCI Card for PC
• Components supported by the r8169 module

La targeta és reconeguda i configurada pel sistema, no cal instal·lar cap controlador addicional,

• 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.
• 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.
• GDevilspie is a user friendly interface to the devilspie window matching daemon, to create rules easily.
