NM with a system wide connection-for Tim and others



Here is Dan Willliams discussion about using NM to produce a global
network connection. I never tried it myself.

Ah :) /etc/network/interfaces is the Ubuntu/Debian equivalent of ifcfg-*
files.  The keyfile plugin doesn't use them.

The keyfile plugin reads files
in /etc/NetworkManager/system-connections, which are essentially .ini
files.  Each section (denoted by [<name>]) is a Setting, and that
setting contains key/value pairs.  It's really just a flat text file
representation of what's in GConf too.  At some point soon I'll make
sure the NetworkManager configuration spec is fully up-to-date, which is
essentially how a keyfile is made.

In the mean time, you can
edit /etc/NetworkManager/nm-system-settings.conf and change
'ifcfg-fedora' to 'keyfile', 'killall -TERM nm-system-settings', then in
the connection editor create your connection and make sure to check the
"System connection" box before hitting OK.  That _should_ ensure that
the connection is saved as a system-wide connection and you'll be able
to poke around the file too.

Let me know if you have any questions.

Dan
