    Internet not connecting (Just hangs)

    Good afternoon.

    Is there any reason why the internet would fail to connect? The tray icon just keeps spinning whether I try ethernet or wifi.

    It *does* work just fine when booting from a stock installation,
    but in the case where it fails, I have layered the / mount with a ro squashfs underneath a rw plain directory.

    I thought it was possible that it didn't work because of permissions, but I'm able to write myself just fine.

    What are all the possibilities that could cause this?

    Thank you.

    Re: Internet not connecting (Just hangs)

    First: You need nameservers in your /etc/resolv.conf:
    Code:
    echo -e "nameserver 8.8.8.8\nnameserver 8.8.4.4" | sudo tee -a /etc/resolv.conf
    Second:

    Add the mtu value of your ISP (mostly 1500) as number instead of "Automatic" in the network-manager profile. Now try to re-connect. If it is not enough then deactivate the hardware encryption of the driver
    Code:
    echo "options ath9k nohwcrypt=1" | sudo tee /etc/modprobe.d/ath9k.conf
    sudo modprobe -rfv ath9k
    sudo modprobe -v ath9k

    Re: Internet not connecting (Just hangs)

    Hey thanks, still nothing!

    Like I say, it works fine when / is mounted the default way. But when I have it boot to an aufs (squashfs+ext4) via simple initramfs scripts, it just hangs and never connects.

    I wonder if there are any missing modules/etc. that initramfs would need to load. Or it could still be a permissions issue, but I don't know enough about these things.

    Those are my only two guesses based on the evidence. Any notes about those?

    Re: Internet not connecting (Just hangs)

    I am happily reporting to you from the fixed internet connection!

    Turns out the problem was due to the layered fs and permissions: apparmor has support issues with these two*.

    I tried connecting via command, and the ubuntu NetworkManager client was what was freezing.

    Code:
    nmcli c
    for the wireless device (wlan0) uuid

    Code:
    nmcli c up uuid  a4caeda7-b57b-4656-ab53-8c7483058e9a
    to manually connect.

    Checking the log within /var/log/syslog

    Code:

    As you can see, apparmor is being denied read access.

    Also, even when I ran

    Code:
    dhclient wlan0
    it complained that libc.so.6 wasn't available, even though it was, so this log made more sense to me.

    then I remembered one of the guides talking about apparmor:
    http://ubuntuforums.org/showthread.php?t=1499338

    *and you can jump to the bug report here:
    https://bugs.launchpad.net/ubuntu/+s...ct/+bug/477012

    which states the solution: LiveDVDs and other layered root filesystems must disable apparmor via kernel options.

    Example grub entry:

    Code:
     menuentry 'Zorin (RAM+USB)' {
            insmod part_msdos
            insmod ext2
            set root='hd0,msdos2'
            linux   /boot/vmlinuz root=UUID=0b23af85-f8c0-4378-87bb-a9ac342d9014 apparmor=0 security=""
            initrd  /boot/initrd
    }

    Re: Internet not connecting (Just hangs)

    Also, it may have had something to do with why resolv.conf was missing nameservers.
