Yes, now I understood this, but because I don't have the time to
investigate the new CAPI interface, I decided to use the old
interface -- and was confused =/ with the devices. But now, that I
know your Howto, it should be easy to use CAPI.

Ok, I checked all the settings again and everything was correct. But
obviously there was a problem with libcapi20 and pppdcapiplugin. I
reinstalled both and then got the following:

$ pon
Plugin userpass.so loaded.
userpass: $Revision: 1.4 $
Plugin capiplugin.so loaded.
capiplugin: $Revision: 1.35 $
capiconn:  1.9
Couldn't load shared library libcapi20.so
libcapi20.so: cannot open shared object file: No such file or directory
Couldn't load shared library libcapi20.so
libcapi20.so: cannot open shared object file: No such file or directory
Speicherzugriffsfehler

(for the non-german speaking people:
	Speicherzugriffsfehler = Segmentation fault)

$ dpkg -l pppd* libcapi* | grep ^ii
ii  pppdcapiplugin 3.3.0.20040728 plugin for pppd to communicate
with CAPI-cap
ii  libcapi20-3    3.3.0.20040728 libraries for CAPI support

$ updatedb
$ locate libcapi20.so
$

So I installed the development package of libcapi20 and then it worked:

$ sudo apt-get install libcapi20-dev
$ pon
Plugin userpass.so loaded.
userpass: $Revision: 1.4 $
Plugin capiplugin.so loaded.
capiplugin: $Revision: 1.35 $
capiconn:  1.9

$ cat /var/log/messages | grep ' IP '
Nov  8 18:52:18 localhost pppd[4967]: local  IP address 145.254.159.78
Nov  8 18:52:18 localhost pppd[4967]: remote IP address 145.253.1.117

I think this should be mentioned in your Howto. Thanks for your help!

A last question on this topic: how has the modem lights-applet to be
configured to work correct (at the moment disconnection does not
work out of the applet) and show connect time and throughput?
'Device: /dev/ppp' or 'Use ISDN' doesn't seem to be right.

Best regards,
