Installare repo atrpms (e settarlo dormiente, per usarlo solo quando si vuole e non ad ogni yum update)
rpm --import http://atrpms.net/RPM-GPG-KEY.atrpms
Creare
/etc/yum.repos.d/atrpms.repo
e incollarci questo
[atrpms] name=Fedora Core $releasever - $basearch - ATrpms baseurl=http://dl.atrpms.net/f$releasever-$basearch/atrpms/stable gpgkey=http://ATrpms.net/RPM-GPG-KEY.atrpms gpgcheck=1 enabled=0
Installare i moduli del kernel:
yum --enablerepo atrpms install ieee1394-kmdl-`uname -r`.`uname -m`
se dovessero fallire le dipendenze con il kernel, cercare un kernel con versione adatta (identica) alla versione del modulo di atrpms
Ora, Controlliamo se si sono installati i moduli per il kernel attivo:
rpm -q ieee1394-kmdl|grep "`uname -r`"
Se il comando da risultati in output, saltare il punto successivo.
Controlli Installazione
Kernel attivo
uname -r
Archittettura
uname -m
moduli ieee1394 installati
find /lib/modules/ -iname *1394*
kernel disponibili (da GRUB)
grep kernel /boot/grub/grub.conf |grep -v ^#
- Controllare quale kernel si avvia default
grep default /boot/grub/grub.conf
Primo della lista
default=0
Avvio
- Se abbiamo verificato che i moduli installati hanno un kernel con versione IDENTICA (es. 2.6.18-8.1.14)
- Se abbiamo verificato che i moduli installati hanno un kernel con architettura IDENTICA (es. i686)
- Se abbiamo verificato che questo kernel con versione e architettura IDENTICA si avvia di default
Si può proseguire
A Caldo
Caricare i moduli direttamente, senza riavviare.
modprobe ieee1394 modprobe raw1394 modprobe ohci1394 modprobe dv1394 modprobe video1394
A Freddo
reboot
Controlli Firewire
Controlliamo la partenza e poi i messaggi del kernel:
dmesg|grep -i 1394
Dovrebbe esservi almeno una riga così:
ieee1394: raw1394: /dev/raw1394 device initialized

Ctrl + A Go to the beginning of the line you are currently typing on Ctrl + E Go to the end of the line you are currently typing on Ctrl + L Clears the Screen, similar to the clear command Ctrl + U Clears the line before the cursor position. If you are at the end of the line, clears the entire line. Ctrl + H Same as backspace Ctrl + R Let's you search through previously used commands Ctrl + C Kill whatever you are running Ctrl + D Exit the current shell Ctrl + Z Puts whatever you are running into a suspended background process. fg restores it. Ctrl + W Delete the word before the cursor Ctrl + K Clear the line after the cursor Ctrl + T Swap the last two characters before the cursor Esc + T Swap the last two words before the cursor Alt + F Move cursor forward one word on the current line Alt + B Move cursor backward one word on the current line Tab Auto-complete files and folder names
