Hi there!
Now that I know how to use NetworkManager via the CLI (see #641902 and
#637769), I configured my Debian sid accordingly. However, there is a
problem with the parsing of /etc/network/interfaces, here is (was) mine:
--8<---------------cut here---------------start------------->8---
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
allow-hotplug eth0
#NetworkManager#iface eth0 inet dhcp
# The Wi-Fi interface
allow-hotplug wlan0
#NetworkManager#iface wlan0 inet dhcp
# ranma: Openmoko GTA02 (AKA FreeRunner)
## <http://wiki.openmoko.org/wiki/USB_Networking>
allow-hotplug usb0
iface usb0 inet static
address 192.168.0.200
netmask 255.255.255.0
post-up /root/bin/openmoko-usb0.sh up
pre-down /root/bin/openmoko-usb0.sh down
--8<---------------cut here---------------end--------------->8---
The above causes eth0 to be configured with the values for usb0:

=====
usb0 is recognized by the ifupdown plugin as 802-3-ethernet, which is
correct (that stanza was for connecting the Openmoko GTA02 via the
cdc_ether kernel module), but the fact that this hijacks eth0 is plainly
wrong. I guess the problem is that usb0 is not treated as a new
interface, distinct from eth0.
I do not know how this bug could be solved: according to the
documentation (shipped by the network-manager-dev package in
/usr/share/gtk-doc/html/NetworkManager/ref-settings.html), however,
there is no option to specify an interface to which a connection applies
(except for a vlan stanza). While it is possible to do that for its
mac-address (but only for infiniband, wimax, 802-3-ethernet and
802-11-wireless stanzas), this does not reflect the flexibility of
/etc/network/interfaces.
Of all the bugs already present in the Debian BTS, I do not think that
mine has already been reported, at least it does not seem to be:
- #433734 (wlan0=$NAME parsing)
- #498931 (wording in /u/s/d/n-m/README.Debian, and probably fixed)
- #508383 (forcing n-m to manage interfaces, and probably fixed)
- #528095 (general /e/n/i parser)
- #617691 (multiple interfaces with static addresses)
- #644631 (IPv4 and IPv6, and probably fixed)
However, it could be related to:
- #527965 (virtual interfaces)
- #606268 (d-i configuration in /e/n/i)
The last one seems to be the real problem, especially:
<http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=606268#153>
However, it seems that commenting or removing eth0 in
/etc/network/interfaces is not enough: if the ifupdown plugin is enabled
(managed=true), then whenever I plug a cable NetworkManager treats eth0
as usb0.
Thx, bye,
