Dear Wolfgang,

If I summarize the URL link previously sent, you should have rather set:
NETCONFIG_DNS_POLICY="STATIC_FALLBACK ppp* NetworkManager"
instead of:
NETCONFIG_DNS_POLICY="STATIC_FALLBACK ppp0 NetworkManager"
in your /etc/sysconfig/network/config

This way both wvdial and kppp ought to correctly work with the /etc/resolv.conf correctly set up.

Best regards,
Philippe

It opens:

which succeed

Then it activates:

With DNS1 and DNS2 which should be provided by your ISP.

Then it opens:
10362 open("/etc/sysconfig/network/config", O_RDONLY|O_LARGEFILE) = 5
10362 fstat64(5, {st_dev=makedev(253, 1), st_ino=272660,

which succeeds.

So the best place where to look is now /var/log/messages.

Before you run kppp from a root account, can you create a new terminal
and issue tail -f /var/log/messages and check what pppd says ?

Then rerun kppp normally (i.e.: without strace)

Philippe,

to put kppprc into /root/.kde4/share/config was really the right point!
Having done this and trying $kppp as su it still crashes, but with the
hint to first set

export $(dbus-launch).

So I did this (whatever it means...), and kppp runs under su *and* under
user! It connects to my internet provider, but I don't get any
throughput, ping says

Network is unreachable

and ssh says

Could not resolve hostname

so this seems to be the old DNS-problem. I did again a
strace -v -e trace=all -f -o kppp.log kppp (this time as su)
and append the kppp.log (it is rather long, sorry for the spam to all
others...).

I can't try efax as a user, because it sits in my root-directory... And
here the rights of my /dev/536ep0:

crw------- 1 root root 240, 1 5. Mär 20:05 536ep0

Dear Wolfgang,

Now when executed as root, kppp attempts to open
/root/.kde4/share/config/kppprc and does not find it.
6841 stat64("/root/.kde4/share/config/kppprc", 0x8141d1c) = -1 ENOENT

You should really do the the following:

$ sudo mkdir /root/.kde4
$ sudo mkdir /root/.kde4/share
$ sudo mkdir /root/.kde4/share/config
$ sudo cp /home/junker/.kde4/share/config/kppprc
/root/.kde4/share/config/kppprc
Then from a root account:
# kppp
or from a user account:
$ sudo kppp
or identically from a user account:
$ su -c 'kppp'

Le 05/03/2012 20:34, Wolfgang Junker a écrit :
Dear Philippe,

this is right, I am doing kppp as user. For this I have changed the
rights of /usr/bin/kppp to

-rwsr-xr-x 1 root root 554352 22. Feb 2011 kppp

(This is how it worked for SUSE 10.3). If I do kppp as root, the
program
crashes rightaway. The "Permission denied" must somehow be an artefact
of strace, I didn't get these messages before, and, as I said, I did
already get an internet connection with kppp (up to the DNS-issue)
with
precisely the present configuration. E.g. the rights of /dev/modem are
as follows:

lrwxrwxrwx 1 root root 10 5. Mär 20:05 modem -> /dev/536ep
crw-rw-rw- 1 root dialout 240, 1 5. Mär 20:05 536ep

I tried now the $strace -v -e trace=all -f -o kppp.log kppp
as root, but, as I said, the program crashes. I append the
kppp.log-file
which was created.

Dear Wolfgang,

As far as it seems you start kppp from your user account and not from
a root account. This explains why you get all these
/etc/ppp/chap-secrets* "Permission denied".

You have this:

[philippe@victor ~]$ grep /etc/ppp/chap-secrets kppp.log
12745 open("/etc/ppp/chap-secrets.new",
O_WRONLY|O_CREAT|O_TRUNC|O_LARGEFILE, 0666) = -1 EACCES (Permission
denied)
12745 unlink("/etc/ppp/chap-secrets.old") = -1 ENOENT (No such
file or
directory)
12745 rename("/etc/ppp/chap-secrets", "/etc/ppp/chap-secrets.old") =
-1 EACCES (Permission denied)
12745 rename("/etc/ppp/chap-secrets.new", "/etc/ppp/chap-secrets") =
-1 ENOENT (No such file or directory)
12745 access("/etc/ppp/chap-secrets.old", F_OK) = -1 ENOENT (No such
file or directory)

Next you have:

12745 open("/dev/modem", O_RDWR|O_NOCTTY|O_NONBLOCK|O_LARGEFILE) = -1
EACCES (Permission denied)
12745 write(2, "error opening modem device !\n", 29) = 29

Looks very strange if efax from a user account is able to open
/dev/modem ! Check for /dev/modem permissions. You might have change
the /dev/modem permissions for hylafax operations.

On my Fedora 16 computer, I have:

[philippe@victor ~]$ ls /usr/bin/kppp
/usr/bin/kppp
[philippe@victor ~]$ ls -l /usr/bin/kppp
lrwxrwxrwx. 1 root root 13 Mar 5 04:29 /usr/bin/kppp -> consolehelper
[philippe@victor ~]$ ls -l /usr/sbin/kppp
-rwxr-xr-x. 1 root root 749004 Dec 3 07:28 /usr/sbin/kppp

If, from my user account, I:
$ strace -v -e trace=all -f -o kppp.vouters.log /usr/sbin/kppp
I see on my screen first that I am not allowed to run pppd unless it
the SUID bit (Capture 19:22:22.png)
Next a dialog to configure kppp (Capture 19:17:21.png).

In conclusion and under Fedora, the usual way is to call
/usr/bin/kppp
which activate a dialog prompting for root password (consolehelper
role), next activating /usr/sbin/kppp from a root context.

Your problem comes from you do not activate kppp from a root context.
Hence all the permission denied.

Kind regards,
Philippe

Dear Jacques, Wolfgang,

I just downloaded the adequate RPM for Fedora 16 containing kppp.
From
a root account, I ran strace over kppp. Because there are numerous
open calls, I edited the file and searched for the "kppp" string.

First kppp attempts to open /root/.kde/share/config/kppprc. From
this
it knows what it must do, therefore directly proposing for me a
connection my old tiscali provider. Next as I previously specified
/dev/modem in this configuration, it opens /dev/modem and tries to
connect. Because the modem is no longer connected to an analog
phone
line, kppp fails with a NO DIALTONE. So its sounds so far very
sane.

Yours truly,
Philippe
