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,

Wolfgang, Ludwig,

Would such information be of some help for you to configure kppp ?

Dear Philippe,

I think your hint to
really solves the problem:

I didn't understand what they were saying but I have put


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

search localdomain site

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!

Hello Ludwig, Wolfgang,

Have a look at this openSUSE bugzilla :

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:



...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.

Betreff: Re: pppd and DNS [WAS:Driver for 536ep-Modem does not

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
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,
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
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
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
of DNS's any more once you have usepeerdns in your /etc/ppp/options



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: ), 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
about the highly industrialisated etc. country Germany), and with my
_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.
