Hi Dan

MM 1.4.12 and NM 1.0.10.



Sorry for the late follow-up; the issue appears to be that either NM or
MM is unable to detect the supported IP types of the modem.  That's why
you get this message:

"Connection requested IPv4 but IPv4 is unsuported by the modem"

Can you grab "mmcli -m 0 | grep IP" and we'll see if MM or NM is at
fault here.

I understand that the connection to bearer takes a bit of time, but
when I
get this:

Does it not mean that I am already connected?? If I bring up PPPD
manually
I could ping and I can wget at this point.

The bearer will be created but it takes a bit to be connected, so
that's probably the state you're in here.





so I did a simple-connect AGAIN:

What version of NetworkManager and ModemManager did you have
again?  I
seem to recall fixing a bug here recently about mis-identifying the
supported IP types.

So after a con up, the modem lost its connection it looks like!!!
but
why?

I'm really out of ideas now. I don't know how to progress further
:(

I've read a lot of documents on setting up devices but

so far:

I added another entry to the ppp connection and called it
radio:
cat radio
[connection]
id=radio
uuid=f6547503-d831-4cc2-bd3c-a958e645552a
type=gsm
#interface-name=ppp0
interface-name=wwan0

The interface part is likely your problem.  interface-name
is
the name
of the NetworkManager control port, which in your case
would be
ttyUSB2
(as reported by 'nmcli dev').  Data ports (like ppp0) are
transient,
they come and go, so locking the connection profile to a
specific
device needs to happen with the control interface name.

If you change that to ttyUSB2 or even just remove it
entirely,
what
happens?

Yeah, you say later you're using NM 0.9.4, which is
extremely old
(23-
Mar-2012) and I'm not surprised some stuff would be
different...





First of all, when I do:

nmcli nm wwan
WWAN
disabled

Then I do:
 nmcli nm wwan on
nmcli nm wwan
WWAN
disabled

nmcli nm status

What's in /var/lib/NetworkManager/NetworkManager.state
?

Can you turn on NM log debugging (might be an nmcli
command
for
that)
and see what NM prints out when you do "nmcli nm wwan
on"?

Dan





I was reading on google somewhere that I need a
config
file
in: /etc/NetworkManager/system-connections/
so I put one in:

cat /etc/NetworkManager/system-connections/radio
[connection]
id=MyWwanConnection
type=gsm

[ipv4]
method=auto

[gsm]
number=*99#
apn=mnet.bell.ca.ioe


restarted NM, did the same thing, no difference.

Any documentation for 0.9.4.0 that I can use to
figure
this out?
Can
someone help me with setting up the radio
connections?
I'm having
no
luck.

How to I enable "service called NetworkManager-
dispatcher or
nm-dispatcher"? When I search for "dispatcher" in
my
filesystem
only
these
come up:
/etc/NetworkManager/dispatcher.d
/etc/dbus-1/system.d/nm-dispatcher.conf
/usr/share/dbus-1/system-
services/org.freedesktop.nm_dispatcher.service
/usr/lib/NetworkManager/nm-dispatcher.action
/usr/sbin/usb_modeswitch_dispatcher


Starting MM as a service makes perfect sense.
The question is however, how do I find out when
to
say
"enable"
the
modem,
or to do a simple-connect? I was planning on
using
the
dispatchers
for all
of that, to automate all of those. So basically:

NetworkManager will take care of that, if 'wwan'
radios
are
enabled.
 See 'nmcli radio'.  As long as 'nmcli radio'
reports
WWAN
enabled,
and
as long as your machine has no airplane switch for
WWAN
(or if
it
does
the switch enables the WWAN), NetworkManager will
enable the
modem
when
it is discovered by ModemManager and it will be
available to
connect
with from NetworkManager.

Recent versions of NetworkManager (1.0.8+) also
have
support
for
WWAN
autoconnect, so I don't think you need a dispatcher
script here
at
all.






- MM starts
- modem comes up, status -> Disabled
   - dispatcher kicks in: status -> Enabled
- dispatcher kicks in: simple-connect

Dispatcher scripts only trigger on connection
up/down,
so you
don't
get
any events on modem status changes.  But that
shouldn't
matter,
since
NetworkManager can take care of all of the WWAN
connection
stuff as
long as ModemManager is up and running (like if its
run
as a
system
service).

Thanks!

Hi guys

I'm trying to experiment with NM dispatchers
but
I can't
seem
to
get
anything done. I have a very basic script
in /etc/NetworkManager/dispatcher.d/02test:

#!/bin/sh -e

echo "Starting ModemManager"
ModemManager --debug &

But it is not running. I have made sure the
scripts and
directories
are executable (a+x). But I cannot seem to
get
the
scripts to
run.

Can someone help me with this please?
NetworkManager --version
0.9.4.0

You probably also need to enable a service
called
NetworkManager-
dispatcher or nm-dispatcher.







Question 2: I wanted to use the dispatcher
script
to
start
ModemManager on startup and to enable the 3G
modem I
have.
Can it
be
done? I have seen examples of how to start a
connection
when
an
interface comes up but nothing that could
help me
with
this.

It looks very wrong to start ModemManager from
a
dispatcher
script.
Those scripts are invoked often and at various
times, you
don't
want to
start ModemManager every time something happens
with a
networking
interface.

Instead, start ModemManager as a regular system
service,
just
like
NetworkManager.
