Package: network-manager Version: 0.9.0-2 Severity: important Hi there!
I have network-manager installed but I do not use it (#641902), thus it does not manage ifupdown interfaces and my /etc/network/interfaces is: --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 ## <http://bugs.debian.org/606268> iface eth0 inet dhcp # The Wi-Fi interface allow-hotplug wlan0 ## <http://bugs.debian.org/606268> iface wlan0 inet dhcp wireless-power on wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf # 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--- Nevertheless, after today's upgrade to 0.9.0-2 I suddenly lost network connectivity. A closer inspection revealed that connectivity is still there (i.e. the eth0 interface is still configured), but the problem is that /etc/resolv.conf is now managed by network-manager, which was not the case before. Here the relevant part from /var/log/syslog: --8<---------------cut here---------------start------------->8--- Sep 17 12:08:54 gismo NetworkManager[1916]: <info> caught signal 15, shutting down normally.

IMHO with "[ifupdown] managed=false" the ifupdown plugin should not be loaded at all, even if it is in the plugin list. 2) I thought that since I have libvirt-bin installed and since virbr0 is not present in /etc/network/interfaces, maybe network-manager wanted to manage it, but this is not the case from the log above. This could be related to #637005, but in my case the default gateway is not modified. Please note that this was not happening with version 0.8.4.0-2 and it is easily reproducible: ===== root@gismo:/etc# ifdown eth0 Internet Systems Consortium DHCP Client 4.1.1-P1 Copyright 2004-2010 Internet Systems Consortium.
