    Ethernet is not Activated at Boot Time

    When my computer first starts I cannot access any ethernet devices (i.e. ifconfig returns only lo) until I run dhclient or dhclient3.

    Here's my /var/log/boot.log:
    Code:
    fsck from util-linux-ng 2.17.2
    Ubuntu_10.04: clean, 307104/655360 files, 2042504/2620587 blocks
    init: portmap main process (829) terminated with status 2
    
    init: portmap main process ended, respawning
    
    init: statd pre-start process (844) terminated with status 2
    
     * Starting AppArmor profiles        modem-manager: Loaded plugin MotoC
    
    Skipping profile in /etc/apparmor.d/disable: usr.bin.firefox
    Anyone know what could be causing this?

    Did you uninstall NetworkManager?

    No, network-manager is installed and up-to-date.

    In Network Connections is your Auto eth, or whatever it is, checked to Connect automatically and Available to all users? If the latter is NOT checked, maybe it only connects when a specific user allowed to connect it is logged in, instead of right away for any user(s).

    Does it automatically connect when "you" log into X?

    Looks like it's fixed itself. Odd.
