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

Dear Wolfgang,

What does happen if you stop the NetworkManager ???
Do you still have a file unusally named /var/run/ppp_resolv.conf.ppp0 ??? Why isn't it named /etc/ppp/resolv.conf ? Anyhow, it is improving as wvdial now gives a primary and secondary DNS address which was NOT the case before.

Dear Jacques,

I tried your suggestions:

I put usepeerdns into /etc/ppp/options, I remove the ethernet-cable, I
do $wvdial with Auto DNS = yes in /etc/wvdial.conf, and obtain

--> Carrier detected. Starting PPP immediately.
--> Starting pppd at Wed Feb 29 17:38:23 2012
--> Pid of pppd: 8823
--> Using interface ppp0
--> local IP address
--> remote IP address
--> primary DNS address
--> secondary DNS address
--> Script /etc/ppp/ip-up run successful
--> Default route Ok.
--> warning, can't find address for ``
--> warning, address lookup does not work
--> Nameserver (DNS) failure, the connection may not work.

and no throughput through the connection. The search for is
a DNS-check built into wvdial by SUSE.
Even if I remove /etc/resolv.conf it is immediately restored by the
NetworkManager with the old entries:

search localdomain site

(the DNS of my DSL). Only if I replace those entries with a static
nameserver, then I get a working connection with wvdial. You said the
other day, that your resolv.conf for ppp sits in /var/run/ppp, but such
a directory does not exist in SUSE 11.4, and if I create it, it has no
effect. A search for other resolv.conf files on my system showed me
1) a file /var/run/ppp_resolv.conf.ppp0 which contains the above DNS


If I add a valid DNS address to this file instead of /etc/resolv.conf it
is ignored, and still no working connection.

2) and a file /var/adm/netconfig/md5/etc/resolv.conf which contains

f40cb6e6e9d7c60cead0424139a8722a -

I have the same impression as Ludwig that this is a SUSE-issue.

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 .

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
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.
