Da es nicht ganz so einfach ist mit ISDN ins Internet zu kommen,
|
|
hab ich mal einiges zusammengeschrieben.(in Englisch, damit auch
|
|
andere etwas davon haben). Ich hab's auch nur mit Hilfe der
|
|
newsgroup geschafft. Vielleicht sind folgende Zeilen fuer einige
|
|
user ja ganz nuetzlich. Fuer Details ist dann das Linux (ISDN) Howto
|
|
ganz nuetzlich.
|

Kurt-Erich Finger
|
|
|
|
---beginners only----
|
|
I tried get into the internet using LINUX and an ISDN-card.
|
|
In the manual for the LINUX distribution (SuSE 6.1) almost everything
|
|
was explained but some crucial information (for a newbee) is missing.
|
|
With the help of this newsgroup I was able to overcome the problems.
|
|
I thought it would be a good idea to write a tiny HOWTO for beginners.
|
|
Since ISDN is not only used in Germany but also in other countries I
|
|
decided to only write it in English.
|
|
(If you think this should not appear here, please let me know.)
|
|
I choose otelo to give a working example, if you prefer another provider
|
|
you can change the details later. If you don't live in Germany modify
|
|
the
|
|
example as necessary.
|
|
|
|
My configuration:
|
|
SuSE 6.1
|
|
Kernel 2.2.5
|
|
ISDN-utils 3.0
|
|
Virgin PC with Win98 and LINUX (loadlin)
|
|
Fritz!card PnP (no other cards)
|
|
|
|
1.Try to find out which IRQ and Port can be used. If you run the card
|
|
already under Win you can find it under >Setting>System.
|
|
(I use IRQ=3, address: 200, I know there could be conflicts with
|
|
COM2!)
|
|
|
|
PnP cards:
|
|
2. run/sbin/pnpdump -c > /etc/isapnp.conf
|
|
Edit /etc/isapnp.conf
|
|
|
|
(READPORT 0x0203)
|
|
(ISOLATE PRESERVE)
|
|
(IDENTIFY *)
|
|
(VERBOSITY 2)
|
|
(CONFLICT (IO FATAL)(IRQ FATAL)(DMA FATAL)(MEM FATAL)) # or WARNING
|
|
|
|
(CONFIGURE AVM0900/-1 (LD 0
|
|
(IO 0 (SIZE 32) (BASE 0x0200)(CHECK) )
|
|
(INT 0 (IRQ 3 (MODE +E)))
|
|
(NAME "AVM0900/-1[0]{AVM ISDN-Controller FRITZ!Card}")
|
|
(ACT Y)
|
|
))
|
|
(WAITFORKEY)
|
|
|
|
The lines (IO (SIZE 32) (BASE Ox0200)) and (INT 0 (IRQ 3 (MODE +E))
|
|
should
|
|
contain the values you want. If necessary remove the # signs at the
|
|
beginning of all above lines.
|
|
|
|
Save the file and start
|
|
isapnp /etc/isapnp.conf
|
|
If you receive an -FATAL- error message, first delete :
|
|
(CHECK) !!!!!
|
|
in the configuration file and start isapnp again.
|
|
If you still get resource conflicts try other IRQ's and addresses.
|
|
Switch the auto configuration for ISA-pnp the BIOS off.
|
|
If you get an ISOLATE PRESERVE error, reboot.
|
|
|
|
all cards:
|
|
|
|
3. Run Yast
|
|
Strictly follow the SuSE manual.
|
|
|
|
A device named ippp0 must exist!!!!!!
|
|
|
|
I assume you want to connect to a provider who uses dynamic IP-
|
|
addresses
|
|
syncPPP and PAP or CHAP for authorising.
|
|
I will describe how you can make a connection to otelo (Germany)
|
|
since
|
|
you can connect directly without an account (username:otelo,
|
|
password: online)
|
|
|
|
Using Yast the IP-Address can be : 192.168.0.99
|
|
Netmask : 255.255.255.255
|
|
Default -gateway : -
|
|
IP-Adress PtP : 192.168.0.1
|
|
The last address could cause problems with t-online, use 192.168.1.1
|
|
|
|
Configure the Name-Server:
|
|
List of IP Addresses : 195.50.149.33 195.50.149.6
|
|
List of Domains : otelo-online.de
|
|
Leave Yast
|
|
|
|
Make sure the file /etc/isdn/isdn.conf contains
|
|
your COUNTRYCODE and AREACODE without the leading 0
|
|
Boot or activate ISDN under Yast to start the network.
|
|
|
|
When you configure with Yast the PAP protocol is set.
|
|
otelo and probably some other provider need CHAP!!!!
|
|
|
|
Let's see what happens if we try to connect:
|
|
isdnctrl dial ippp0
|
|
will try to connect to your provider.
|
|
Check /var/log/messages!
|
|
If you don't see local and remote IP addresses but
|
|
ISDN error messages or a 'Modem Hangup' something went wrong.
|
|
To find out you need more information in the messages file.
|
|
Edit /etc/rc.config.d/I4L_sp_option.rc.config
|
|
I4L_VERBOSE=yes
|
|
and in /etc/ppp/ioptions
|
|
uncomment debug.
|
|
This should give enough information in the /var/log/message file.
|
|
|
|
If you try to connect to otelo you will find that your computer
|
|
is sending a string containing <PAP> and otelo sends <CHAP> indicating
|
|
that you have to change the protocol from PAP to CHAP.
|
|
To change the protocol you have to add
|
|
user otelo in /etc/ppp/options.ipp0
|
|
add
|
|
# client server secret IP addresses
|
|
"otelo" * "online"
|
|
to /etc/ppp/chap-secrets and delete the corresponding line in
|
|
/etc/ppp/pap-secrets.
|
|
|
|
Start isdnctrl dail ippp0 and watch /var/log/messages. If you seen see
|
|
IP addresses you made it.
|
|
Otherwise read some of the links in the Weekly ISDN FAQ of E.Corry.
|
|
|
|
Now you have a connection to your provider and you may want to use the
|
|
Netscape Navigator.
|
|
First another problem needs to be solved:
|
|
If no traffic is on the line it will be cut and the default route will
|
|
be deleted.
|
|
(You will find the time-out in /etc/rc.config.d/I4L_option.rc.config
|
|
I4L_IDLETIME)
|
|
|
|
The file /etc/ppp/ip-up (ip-down is only a link to ip-up) has to be
|
|
modified:
|
|
BASENAME=`basename $0`
|
|
INTERFACE=$1
|
|
DEVICE=$2
|
|
SPEED=$3
|
|
LOCALIP=$4
|
|
REMOTEIP=$5
|
|
|
|
case "$BASENAME" in
|
|
ip-up)
|
|
/sbin/route add default gw $REMOTEIP dev $INTERFACE
|
|
#/sbin/init.d/route start $INTERFACE
|
|
;;
|
|
ip-down)
|
|
/sbin/route add default gw $REMOTEIP dev $INTERFACE
|
|
#/sbin/init.d/route start $INTERFACE
|
|
;;
|
|
*)
|
|
;;
|
|
esac
|
|
|
|
(from http://www.suse.de/sdb/de/html/isdn-defroute.html (dynamic IP-
|
|
numbers))
|
|
|
|
Now you can start
|
|
isdnctrl dial ippp0
|
|
startx (kde)
|
|
Netscape
|
|
|
|
I hope it works with you!
