networkmanager-openvpn will not connect
Using networkmanager-openvpn- 0.9.8.4 patched to use libsecret, I am unable to
connect.
After configuring the vpn connection using gnome-control-center, I'm prompted
for the vpn password, but after entering it I get the error Connection
activation failed: the VPN service failed to start.
Running from the command line gives the output below.
The tun module is compiled into the 3.8.13 kernel I'm using (CONFIG_TUN=y), is
this the source of the error?
Regards
John

NM refuses to manage a VLAN
Dear All:
I am trying to migrate an existing setup. To that end, I defined
a connection with nmcli c add type vlan. Result is like this:
[root@elanor network-scripts]# nmcli conn show configured

Then, I make sure that device alias is deleted:
[root@elanor network-scripts]# ip link delete dev ethmain.4
[root@elanor network-scripts]# nmcli dev
DEVICE TYPE STATE
ethmainethernet unmanaged
lo loopback unmanaged
ethmain.2 vlan unmanaged
ethmain.3 vlan unmanaged
ethmain.5 vlan unmanaged
[root@elanor network-scripts]#
So far, so good. But then...
[root@elanor network-scripts]# nmcli c up id vlan-ethgray
Error: Connection activation failed: Device not managed by NetworkManager or
unavailable
Oops!
[root@elanor network-scripts]# nmcli dev
DEVICE TYPE STATE
ethmainethernet unmanaged
lo loopback unmanaged
ethmain.2 vlan unmanaged
ethmain.3 vlan unmanaged
ethmain.4 vlan unmanaged
ethmain.5 vlan unmanaged
So, NM creates the correct alias (visible with ip link or ip addr),
but bails before setting any addresses on it. This happens with
NetworkManager-0.9.9.0-40.git20131003.fc20.i686.
Any ideas how this could be fixed?

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.
Did you see https://wiki.gnome.org/Projects/NetworkManager/Developers ?
especially
https://developer.gnome.org/NetworkManager/0.9/ref-settings.html
(or try `man nm-settings` if you have the manual pages installed)
Probably host name too (not sure if that's doable in NetworkManager).
SaveHostname , see
https://developer.gnome.org/NetworkManager/0.9/spec.html
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.
I would say, this *should* all work (without knowing your exact
requirements)
Is there some documentation as to how these various network types are
specified as dict objects to NetworkManager?
I think above links is a good starting point, otherwise just ask.
