Configurazione di una connessione ISDN
Configurazione del modulo della scheda ISDN
Debian Sarge
Assicurarsi che sia già installato il pacchetto hotplug, per caricare il modulo giusto:
sudo apt-get install hotplug sudo /etc/init.d/hotplug restart
Se si stà installando la scheda Eicon Diva Pci 2.01, modificare i parametri di carimento del modulo hisax dando il tipo di scheda giusto ed il protocollo EuroIsdn:
Debian Etch & Debian Sarge
sudoedit /etc/modprobe.d/arch/i386 ... options hisax type=11 protocol=2 ...
Ricaricare il modulo hisax:
sudo rmmod hisax sudo modprobe hisax
Il syslog mostrerà:

Caso di linea punto-punto
ATTENZIONE: se la linea isdn usa un centralino, può darsi che sia configurata non nella modalità standard (punto-multipunto) ma sia una punto-punto, spesso assciato ad una numerazione a ricerca automatica.
Se così fosse, quando si fa un dialing, si ottiene l'errore:
Aug 8 11:58:25 firest kernel: ippp0: dialing 1 7027020000... Aug 8 11:58:25 firest kernel: isdn: HiSax,ch0 cause: E001B Aug 8 11:58:34 firest kernel: isdn_net: local hangup ippp0 Aug 8 11:58:34 firest kernel: ippp0: Chargesum is 0
L'errore E001B (man isdncause E001B) indica proprio questa configurazione.
OCCORRE STACCARE TUTTI GLI ALTRI DISPOSITIVI ISDN PER POTER USARE QUESTA LINEA, DATO CHE LA MODALITA' PUNTO-PUNTO PERMETTE DI COLLEGARE UNA SOLA PERIFERICA ALLA BORCHIA ISDN
Per mettere la scheda in modalità point-to-point è sufficiente lanciare il comando:
sudo hisaxctrl HiSax 7 1
Si leggerà in syslog:
Aug 8 12:58:25 firest kernel: HiSax: set card in PTP mode Aug 8 12:58:25 firest kernel: LAYER2 WATCHING ESTABLISH
(naturalmente "sudo hisaxctrl HiSax 7 0" mette in point-multipoint....)
Per mantenere questa modifica al reboot, inserire questa riga in /etc/modutils/actions:
sudoedit /etc/modutils/actions ... post-install hisax hisaxctrl HiSax 7 1 ...
Applicare la configurazione:
sudo update-modules
Verificare:
cat /etc/modules.conf | grep hisax post-install hisax hisaxctrl HiSax 7 1
Oppure inserire in /etc/isdn/device.ippp2 (riga 99):
....
case "$dowhat" in
start)
# Set point-to-point mode
hisaxctrl HiSax 7 1
# XXX_
...
Se non si stacca il centralino o l'altra periferica isdn dalla borchia isdn, si ottiene l'errore E0251
Configurazione del numero da chiamare
Mettere il numero della propria linea SENZA PREFISSO in /etc/isdn/device.ippp0
LOCALMSN='26113644' # XXX_
Oppure lasciare
LOCALMSN='0' # XXX_
Mettere il numero in /etc/isdn/device.ippp2
sudoedit /etc/isdn/device.ippp2 ... REMOTEMSN='7023456789'
Configurare i dati per l'autenticazione
Modificare in /etc/isdn/ipppd.ippp2 :
sudoedit /etc/isdn/ipppd.ippp2 ... name mpgalimberti@galimberti.net # set local name for auth XXX_ noauth defaultroute #ms-get-dns
Inserire le password in /etc/ppp/pap-secrets :
sudoedit /etc/ppp/pap-secrets ... "mpgalimberti\@tiscali.it" "*" "mpgali"
Inserire le password in /etc/ppp/chap-secrets:
sudoedit /etc/ppp/chap-secrets ... "mpgalimberti\@tiscali.it" "*" "mpgali"
Riavviare i servizi
sudo /etc/init.d/isdnutils stop; sudo /etc/init.d/isdnutils start

'ATTENZIONE: se dovessero esserci degli errori, e si rendesse necessario cambiare i files di configurazione, qualsiasi essi siano, è NECESSARIO riavviare isdnutils:
