NetworkManager Disables Eth0

[David]

Binary package hint: network-manager

The NetworkManager is disabling my ethernet card and making it impossible to login to Intrepid. The ethernet works fine in single user recovery mode.

lsb_release -rd returns: 8.10

uname -a (in single user mode) returns:
  Linux CERTIBY-DEV1 2.6.27-7-generic #1 SMP Thu Oct 30 04:12:22 UTC 2008 x86_64 GNU/Linux

apt-cache policy network-manager returns:

    Installed: 0.7~~svn20081018t105859-0ubuntu1
    Candidate: 0.7~~svn20081018t105859-0ubuntu1
    Version Table:

         500 http://archive.ubuntu.com intrepid/main Packages
         100 /var/lib/dpkg/status

I upgraded from Hardy (which worked fine) using sudo do-release-upgrade

In /var/log/daemon.log I see:

   CERTIBY-DEV1 NetworkManager <info> (eth0) device state change: 1 -> 2
   CERTIBY-DEV1 NetworkManager <info> (eth0) preparing device.

Pedro,

I did something a long time ago that allows network manager to start
without turning off my Ethernet card, though many things about Intrepid
remain extremely flaky. I am just hoping that the next version of the
O/S works better.

Sorry that I cannot help.

David

I have similar issues. I've had issues with network-manager and avahi-daemon since I installed some opensync and bluetooth packages to sync my pda. I think it started because it tried to add my bluetooth dongle as eth1 and use avahi-daemon to set up local dns maybe? thats just a guess because i don't really understand what changes were made.

But the only way I could get it to reliably work is to turn off nm-applet auto start in xfce4-session-settings.
Then manually configure my static IP address and nameserver. I also changed the avahi setting to 0 below.

Don't know why or how this fixed my issue but it did.

~$ cat /etc/network/interfaces
       auto lo eth0
       iface lo inet loopback

       iface eth0 inet static
            address 152.19.35.137
            netmask 255.255.0.0
     gateway 152.19.1.1

~$ cat /etc/resolv.conf
nameserver 152.19.4.1

~$ cat /etc/default/avahi-daemon
# 1 = Try to detect unicast dns servers that serve .local and disable avahi in
# that case, 0 = Don't try to detect .local unicast dns servers, can cause
# troubles on misconfigured networks
AVAHI_DAEMON_DETECT_LOCAL=0
