Description István Tóth 2000-10-10 05:10:23 EDT
The ipppd in ISDN4k-utils has an undocumented option "callback 6", that
enables it to initiate callback using the cbcp protocoll.
This feature works very well (I am using it with a Cisco terminal server),
but it cannot be configured with isdn-config, and the /etc/init.d/isdn
script has to be hacked to enable setting this option.

So I propose the following changes: Make the /etc/init.d/isdn script also
handle the callback option, and add the option to set this in isdn-config,
tool, too.

Also regarding the /etc/init.d/isdn script, with the current script it is
not possible to add _additional_ options ipppd, if you specify an options
file, it will overwrite all ippd options set in

I have added the follwoing lines to /etc/init.d/isdn:

       # Use provider options file instead
        if [ -f "/etc/ppp/options-$1" ]; then
            options="file /etc/ppp/options-$1"

+        # Add the options from the provider options file
+        if [ -f "/etc/ppp/extra-options-$1" ]; then
+            options="$options file /etc/ppp/extra-options-$1"
+        fi

        # Start ipppd
        /usr/sbin/ipppd $options

This change would make it easier to support funky ippp options without
having to hack the init scripts. (If this extra options could be set from
within isdn-config, as an advanced option, that would be even nicer.

It's fixed. isdn-config will be obsolete in 7.1. A replacement is
