Now make executable with 'chmod 700
isdn-on.ippp0'
Execute the command by typing 'isdn-on.ippp0'
Setting up the
`ioptions' files
The daemon
that links to the ISDN card is 'ipppd', and it communicates via
interfaces 'ippp0', 'ippp1' etc. just like 'eth0' communicates with the
Network adaptor. Several instances of ipppd can be running at the same
time. The file /etc/ppp/ioptions is read by ipppd whenever it is loaded.
To be able to dialout to an ISP, and allow external access to this
host, or even dialout to a different host or ISP, you must run an ipppd
for each interface you want active. Since ipppd (see 'man ipppd')
always reads /etc/ppp/ioptions, only common values should be present in
/etc/ppp/ioption. The values specific to an interface will be stored in
/etc/ppp/ioption.ippp0, and /etc/ppp/ioptions.ippp1 etc.
The `ippp0'
interface is added in the script above. Type `ifconfig' and you should
see the interface details.
I will concentrate on the option files necessary to bring up the link
to Demon Internet. Later I will cover accessing an ISP using dynamice
IP's.
Create
`/etc/ppp/ioptions'. It should contain -
#/etc/ppp/ioptions.
# Options file with common parameters.

NOTE: The lines
-vj, -ac -pc, etc disable various compression options. Using no
compression has given the most reliable connection with some versions of
isdn4k-utils, but it is worth checking with newer versions to see if
compression options are now available.

Now create the
/etc/ppp/ioptions.ippp0 file with details for Demon Internet.

Make it executable with 'chmod 700
isdn-off-exec'
May not be needed:
/root/bin/isdndown
Now create a
script to remove the ISDN set-up.
# /root/bin/isdndown
# Script to remove the ISDN setup
kill `cat /var/run/ipppd.pid`
ifconfig ippp0 down
isdnctrl delif ippp0
kill `cat /var/run/isdnlog.isdnctrl0.pid`
#modprobe -r hisax

The last line removes the hisax driver, and
is currently commented out. Note that the quote marks around the `cat`
command on the kill lines are both open quote marks
Make this
executable.
