Re: Load new profile in Network manager v0.9.4 using cli (without nm-connection-editor) ?

[Stanislav Bocinec <svacko gmail com>]

Hello Thomas,

thanks for your answer.

There are some business needs behind this migration to NM requirement...

Reg. nm-connection-editor - i already tried to generate a new profile using nce and then just copy it to the proper location but NM just ignores it.

However, i found a solution -  http://cgit.freedesktop.org/NetworkManager/NetworkManager/tree/examples/python/dbus/add-connection.py - by using this python script i'm able to add NM connections on the fly without anything else, problem solved :)

This connection is in memory only, and generated automatically
because there was no other connection.

you certainly should be able to provide "keyfiles"
in /etc/NetworkManager/system-connections/. Make sure they are owned by
root and `chmod 600`.


Maybe, you also have to configure

  [main]
  plugins=ifupdown,keyfile

in /etc/NetworkManager/NetworkManager.conf. See `man
NetworkManager.conf`, but actually I think that "keyfile" is enabled
always (*) and depending on whether you want to use ifupdown, that might
be correct.

(*) at least on recent NM. 0.9.4 is already a bit older, didn't check
there.


... I did not fully understand, would you prefer to
provide /etc/network/interfaces instead of keyfiles? The former has the
advantage that it works together with Ubuntus default network
configuration. However, there might be options that are not available or
not supported. "keyfile" supports everything.

you can use nm-connection-editor to help you generating an initial
configuration. Then you can copy the keyfile around (and possibly
adjusting by hand).
