Mobile broadband on an embedded 3G modem
Hi all, We're trying to get a 3G modem connection going on an embedded device. The modem is a MultiTech SocketModem MTSMC-H5-IP and it appears on /dev/ttyAPP3 (i.e. hardware UART port on the SoC). If I run `screen /dev/ttyAPP3 115200`, I can interact with the modem, it all works. The challenge, is getting NetworkManager 0.9.10.0 to talk to this modem. When I run `nmtui`, no option for adding the mobile broadband connection appears, I suspect because NetworkManager doesn't know the 3G dongle exists. How do I tell it where to look?

Rather than trying to bend Polkit/ConsoleKit/NetworkManager to my will in talking directly to www-data, I've done something that's perhaps a little kludgy, but then again, perhaps not. I've written a DBus service which is launched from the Django manage.py script. It listens for requests from www-data to update connections and acts on them. So when I create a connection, the web application writes to the database, then sends a DBus message to the agent telling it what ID it just created. The agent picks this up, generates the configuration dict and feeds NetworkManager with it. That's where it's kludgy. The flip side is that if the configuration changes, I can pick up on the signals NetworkManager emits to update the Django model. I haven't done this as yet, but seeing as I've got the potential there I might as well. The DBus service runs as 'root', and is launched by dbus-activation so there's no issues with talking to NetworkManager, and I'm now able to add and delete network connections from the web UI. If people on the list here are interested in such a module for Django to control NetworkManager, let me know and I'll see what I can organise.

As thomas already mentioned, these should be covered in the API
documentation that he linked. Note that IPv4 addresses are arrays of

address members are network-byte-order. So the code in Python to push
that into the dict that can be sent over D-Bus is something like this,
taken from:
[...]
this is mainly because Python doesn't have strongly-typed variables, but
D-Bus does, so you have to tell Python what the mapping is between the
Python types and the D-Bus types.
Yep, just experimenting with python-networkmanager, it seems this is one
of the details it looks after: IP addresses are translated to strings,
endianness is taken care of, etc. Dicts are plain Python dicts.
Just looking at the documentation there though, am I correct in assuming
that to set up a simple connection, you would have a dict of the form:
{'connection': { global connection settings },
'ipv4': { IPv4 address settings },
'ipv6': { IPv6 address settings },
}
and so the 'connection' bit would be mandatory, and you might have *one*
each of the other setting types?

The type setting (eg 803-3-ethernet, 802-11-wireless, gsm, cdma,
bluetooth, etc) is required too. The 'type' setting and the
'connection' setting are the only required ones. Usually you'd lock the
connection to a MAC address with the type setting, or it would contain
stuff like MTU, SSID, and other hardware-specific stuff, so you can't
really leave it out.
Okay, so there's a setting called type too, that I presume is distinct
from the connection setting's type attribute. i.e. the minimum
required:
{'connection': {...},
'type': {...},
...}
Where do I find information on this type setting? Doing a search for
type setting on
https://developer.gnome.org/NetworkManager/0.9/ref-settings.html shows
no matches.
IPv4 and IPv6 are optional if you want automatic (DHCP, PPP/WWAN, etc)
addressing, but obviously if you want static you have to specify one or
both.
Ahh so a minimal one might give a 'connection' object, whose 'interface'
attribute references one of the physical network ports, and it'll just
configure the network via DHCP.

Creating NetworkManager connections via DBus API
Hi all, I'm in the process of writing a web frontend for a small Linux-based appliance, thus am in need of a tool for configuring the network interfaces. NetworkManager seems to be a good fit in that it supports a wide variety of networks and runs as a daemon which is then accessed by unprivileged users. The web front-end software we're writing is based on Django, and I'm creating a collection of models which will represent the configuration of the network interface. There's a nice Python library; python-networkmanager which provides an abstraction ontop of DBus so accessing NetworkManager isn't too painful. https://pythonhosted.org/python-networkmanager/ So my task now, is knowing the name of a network device, its intended IP address, routes, DNS configuration, etc, is to figure out how to tell NetworkManager about it and get it to connect. Now, there's a DBus spec which describes the objects here: https://developer.gnome.org/NetworkManager/unstable/spec.html Great. By the looks of things, I create a org.freedesktop.NetworkManager.Settings.Connection object, then hand that to org.freedesktop.NetworkManager's ActivateConnection method. But how do I encode my address settings in a Settings.Connection object? Where do I find a list of the settings and their possible values?

There's actually a bunch of Python examples here:
http://cgit.freedesktop.org/NetworkManager/NetworkManager/tree/examples/python
that use both plain dbus and Python GObject introspection. The GObject
introspection ones are similar to python-networkmanager actually. I'm
not sure how python-networkmanager accepts a new connection to add, but
perhaps the examples give you an idea how to do that?
Ahh okay, that's handy. I'll have a dig through those and see what I
can uncover.
I'd expect it to
be a normal dict of dicts like the examples above show which is then
passed to org.freedesktop.NetworkManager.Settings.AddConnection().
It does appear that way, I tried pulling the information out for my
Ethernet connection and got:
In [9]: conn.GetSettings()
Out[9]:
{u'bridge': {u'interface-name': u'br0', u'stp': False},
u'connection': {u'id': u'Bridge Ethernet',
u'type': u'bridge',
u'uuid': u'357c4dcf-2600-45fa-8687-05f4c2cb82b4',
u'zone': u'work'},
u'ipv4': {u'addresses': [],
u'dns': [],
u'may-fail': False,
u'method': u'auto',
u'routes': []},
u'ipv6': {u'addresses': [], u'dns': [], u'method': u'auto', u'routes': []}}
It seems NetworkManager doesn't much like my hand-configured bridge
(won't see its IP address), but that's a side issue.
What I'm curious about is what sorts of keys and values are expected in
that dict of dicts? At a basic level I need to be able to set IP
addresses, static routes, DNS servers, domain and DNS search order.
Probably host name too (not sure if that's doable in NetworkManager).
At least that will be the starting point. The devices in question we're
setting up will be headless boxes, basically appliances, intended to
poll energy meters in an energy management system and pump the data
elsewhere.
So mostly wired access, there's a couple of places where we have a
bridges and OpenVPN for technical support on some sites and I envisage
some possibly needing cellular 3G support.
No one has approached us with the need for WIFI support, but I bet
someone will some day, thus it'd be useful to know how that's configured
too.
Is there some documentation as to how these various network types are
specified as dict objects to NetworkManager?
