Hi,
I'm looking to change the IP address, prefix, gateway, etc.. of a connection
through the NM and its DBus API but the only examples I have found are for
version 0.8.x in which the Update method on
org.freedesktop.NetworkManager.Settings.Connection can be set using the
parameters returned by the method GetSettings. Changing the IP address was
done by modifying the dictionary named 'ipv4' in the settings returned and
passing the new settings through the Update() method on the same interface.
I am using Debian and NM 0.9.4 and with the upgrade there seems to be no more
ipv4 setting returned by GetSettings() so I'm not sure if I can insert a new
dictionary entry for the ipv4 in the returned settings and simply return it
to Update() as before.
Correct. You can insert the new dictionary for the ipv4 setting and
send all the previous settings, plus the new ipv4 setting, back with
the Update() call. That will save it to disk.
Also, I noticed org.freedesktop.NetworkManager.IP4config does have a property
name Addresses which returns the type of information I am looking to modify
(but missing the dns infos in the old ipv4 structure) but there is not way to
modify and set these parameters through the interface or any other.
The IP4Config interface is the runtime configuration, after the
Connection and it's associated settings have been applied to the
interface. So for example, the Connection settings might specify
method=auto (ie, DHCP), and then when DHCP is run, the actual IP
address and DNS settings populate the IP4Config object. The Connection
is only the saved profile configuration information used to connect to
the network, but it does not store any runtime configuration in NM 0.9.8
and lower.
Can anybody advise me on the right course to modify the IP settings in NM
0.9.4+?
Depending on the language you're working with, there are some examples
here:
http://cgit.freedesktop.org/NetworkManager/NetworkManager/tree/examples
I've just added two python examples which should show what needs to be
done:
http://cgit.freedesktop.org/NetworkManager/NetworkManager/tree/examples/python/dbus/update-ip4-method.py
http://cgit.freedesktop.org/NetworkManager/NetworkManager/tree/examples/python/gi/update-ip4-method.py
Let me know if you have more questions!
