Searching the web for this, reveals, that this seems to be very common
with UMTS dialup, but works nevertheless, if the DNS is correct, e.g.
something like If I enter that manually into
/etc/resolv.conf, the connection works. But why is ppp not getting DNS

Any chance you could patch the nm-pppd-helper binary to write all the
options it gets out to a file somewhere and then send that to the list?

You mean nm-ppp-manager.c or the ppp executable? nm-ppp-manager already outputs the command line: Feb 7 21:38:35 shelbyville NetworkManager: <debug> [1202416715.931005] nm_ppp_manager_start(): Command line: /usr/sbin/pppd nodetach lock ttyUSB0 noauth refuse-eap refuse-chap nodeflate usepeerdns plugin /home/mab/install/lib/pppd/2.4.4/

If you mean ppp or something else, it would have to wait until tomorrow.


That's what I had to do when debugging the P-t-P address thing, because
pppd squelches any output the plugin might print.  That would help us
figure out if your remote side has the issue, or if it's a
NetworkManager problem, and if so where in NetworkManager the problem


That bit looks suspect...  Never seen that message from pppd before, but
it might have something to do with it.  I had to modify the ppp helper
code when adding CDMA support to grab the remote IP address and set that
as the interface's P-t-P address, otherwise my Sprint cards wouldn't
work.  Previously to this, the interface's P-t-P address was getting set
to the same address as the interface address.

Ultimate fail:

   if (ho->hisaddr == 0) {
	ho->hisaddr = htonl(0x0a404040 + ifunit);
	warn("Could not determine remote IP address: defaulting to %I",


Maybe NetworkManager should trap that magic and replace it with the
interface address like use to happen before.
