Jacques, Wolfgang, Ludwig,
An excellent way to troubleshoot kppp with what Jacques states is to run
strace over kppp and to analyze each open to get the device/file name
kppp attempts to open.
To run strace, refer to:

Friends,
Excuse me for a trivial check which you perhaps did not yet hear about.
Actually as far as I remember KPPP works using wvdial behind the scene
with a configuration file wvdial.conf hidden elsewhere than the regular
place. A sudo updatedb followed by a sudo locate wvdial.conf will reveal
if there is such a file and probably show as /dev/modem as device in
that file.
A trick is needed with kppp, and I forgot which, to make kppp know the
name of the driver device. If I remember well kppp tries /dev/modem and
allows the user, through the configuration menu. to use /dev/ttyS1
through /dev/ttyS4 and abandons if no modem found. I think but I am not
sure that the trick is to place the right device name in the hidden
wvdial.conf.
It is of course tempting to think of a link of the actual driver device
to /dev/modem but it must be re-created after the port creation at each
boot because the port (the udev thus the /dev) isn't there yet !
I must add that I have not had any experience with SuSE which, again,may
well have its own way to do this thing.

Run minicom and issue ATI AT commands to check whether the modem is
responding. Your "modem doesn't answer" with kppp tells me the modem
is not responding to ATI AT commands.

Dear Wolfgang,
Any news from you with kppp ? Did you progess on this topic ?
Dear Ludwig,
As far as I can guess and possibly thanks to mails exchanges with
Wolfgang, you should now have a working wvdial/pppd connection.
Would it happen you would also be interested with kppp ? Please let
everyone know.
Grüsse aus Fontainebleau/Frankreich,
Philippe

Dear Philippe,
I think your hint to
https://bugzilla.novell.com/show_bug.cgi?id=465679
really solves the problem:
I didn't understand what they were saying but I have put
NETCONFIG_DNS_POLICY="STATIC_FALLBACK ppp0 NetworkManager"
into my /etc/sysconfig/network/config (or equivalently into the
mask of
the editor of YAST for the Network-configuration under
/etc/sysconfig).
Now if I plug off the ethernet cable and do $wvdial I get a working
internet connection and ppp's DNS-address is dynamically added to
/etc/resolv.conf:
search localdomain site
nameserver 195.50.140.248
nameserver 145.253.2.203
nameserver 192.168.0.1
I still couldn't make kppp work (it says "modem doesn't answer") but I
hope to resolve this issue also.
Many thanks for your help!
Wolfgang

Hello Ludwig, Wolfgang,
Have a look at this openSUSE bugzilla :
https://bugzilla.novell.com/show_bug.cgi?id=465679
I think this can indeed help you. This is very openSUSE specific
Kind regards to both.

Hello all,
DHCP is installed, the system accepts to get adresses from a router
with DHCP server.
Added usepeerdns to /etc/ppp/options. As described in man pppd, the
following files were created:
/var/run/ppp_resolv.conf.ppp0
nameserver 195.129.111.50
nameserver 195.129.111.49
/var/run/ppp_resolv.conf.dsl0
nameserver 217.0.43.1
nameserver 217.0.43.193
...but apparently not passed to pppd ("ppp 2.4.5-5.1-i586 from
vendor
openSUSE"). Browsing via dial-up modem failed. The nameserver
addresses are correct.
My DSL device is new, but rather old fashioned. It is merely a
modem,
not a router. It does nothing else than convert IP-packages to DSL
format and vice versa. It can not be configured, it gets the
internet
access data every time it is startet from pppd resp. smpppd.

Ludwig

Betreff: Re: pppd and DNS [WAS:Driver for 536ep-Modem does not
compile]
Dear Ludwig,
Please forgive me to remind here, since I do not know you, that
wvdial/wdialconf are not programs that operate the communication
but
rather friendly utilities that prepare the parameters (data) for
the
real program which does the work, pppd.
Now please can you tell us if there is or not a line usepeerdns in
your file /etc/ppp/options
If there is not, please add that line.
Then please try to connect to your analog modem ISP with wvdial and
Auto
DNS = yes, do not worry for what there is or not in
/etc/resolv.conf
because in this case pppd should NOT use /etc/resolv.conf,
disconnect
the cable from DSL to PC to make sure that you use the analog
modem,
and
try to surf the Web, like Google or others. Does it work?
If it works (it should), reconnect your DSL, make it work by adding
the
DSL DNS in /etc/resolv.conf if necessary (see Note) and give the
following commands in a separate window as superuser (the first
takes
time), while wvdial (pppd) is still running: updatedb ,then this
long
composite command for f in `locate resolv.conf* `;do echo $f;cat
$f;done so that you can see the contents of the various
resolv.conf present on your computer.
Note: if your DSL box is not old, and I am sure you were given a
brand
new one since DSL is new in your place, configure your PC
(Linux) for
the DSL connection to take DNS's from the DSL box (do not define
/etc/resolv.conf and make it clear in the network s\manager
definitions, no local name server, no local DNS). Your DSL box
normally
comes configured such that the DSL box takes itself
automatically the
DNS addresses from the network. You may want,and even need, to
check
that your DSL box is configured like that. That way you should not
hear
of DNS's any more once you have usepeerdns in your /etc/ppp/options
.
Regards
Jacques
n 02/29/012 02:00 PM, Ludwig Gebauer wroteresolv.conf
With "Auto DNS = yes" in wvdial.conf, DNS addresses show up in the
wvdial protocol, when running wvdial (ISP: www.yooline.de ),
whether
network manager is activated or not. wi And whether network
manager is
activated or not, I have to edit resolv.conf manually. Since a few
weeks, DSL exists here in my village, 12 km afar from Brunswick (so
much
about the highly industrialisated etc. country Germany), and
with my
DSL
_modem_ (not a modem _router_!) I have the same effect: DNS
addresses
must be transferred manually to resolv.conf. Seems to be an
openSUSE
11.4 issue.
