    Ubuntu 12.10 vs. BootMed

    Caveat: I'm a newbie to ubuntu and am running the Live CD's for Bootmed and ubuntu 12.10

    I can browse my work network with Bootmed's ubuntu flavor and, when prompted for my network credentials, can provide them and access network folders. When I try to do the same thing with ubuntu 12.10 (32-bit), it will not accept my credentials. I get the same thing with ubuntu 12.10 (64-bit), but I get an additional failure to mount resources initially so I'm focusing on just getting 32-bit to work for now.

    I looked at the network settings for Bootmed, which defaults to the following:
    Connection Name = Auto eth0 // "Connect Automatically" is checked // "Available to all users" is checked
    Wired tab: MTU = automatic
    802.1x Security tab: Use 802.1x security is unchecked
    IPv4 Settings tab: Method: Automatic (DHCP) & "Require IPv4 addressing" is checked
    IPv6 tab: Method: Ignore

    When I look at the network settings for ubuntu 12.10 (32-bit), I make the following changes to try to mimick Bootmed with the following results:

    After changing the connection name and changing IPv6 to Ignore, I get an error "Sorry, Ubuntu 12.10 has experienced an internal error.
    Details:
    ExecutablePath:
    /usr/bin/nm-connection-editor
    Package
    network-manager-gnome 0.9.6.2-Oubuntu6
    ProblemType
    crash
    Title
    nm-connection-editor crashed with SIGSEGV in g_type_instance_get_private()
    ApportVersion
    2.6.1-Oubuntu3
    Architecture
    i386

    This is all being done from Live-DVD's on an HP Elitebook 8770w with 8GB of RAM and a 500GB drive, which normally boots to Win7 x64. Perhaps the BootMed image simply has the necessary drivers, but I can see the folders in both ubuntu distros - I just can't get my credentials to work for ubuntu 12.10. I'm guessing that since ubuntu is loaded into RAM that the write-back update should change values in RAM and not actually try to write back to the DVD-R disk, which could never be updated.

    Our DNS servers don't support IPv6 so I thought perhaps this may be the issue and hoped to be able to easily diable IPv6. It's not critical to get this working, but if it's a simple config change, then I'd love to understand it to encourage me to work more with ubuntu. It has been decades since I worked in UNIX and it's nice to get away from Windose ... even if for a little while

    Thanks for the help !!!

    Re: Ubuntu 12.10 vs. BootMed

    Hi,

    what hardware is in use? Do you want to install later or using the LIVE-DVDs permanently? Please check in a terminal (CTRL+ALT+T) the outputs of:
    Code:
    lspci -nnk
    lsusb
    lsmod
    iwconfig
    rfkill list
    For deactivating IPv6 go to the network-manager-applet->IPv6-settings and "ignore".

    Re: Ubuntu 12.10 vs. BootMed

    Wow, that's the quickest reply in a forum that I've ever received - Thank You !!

    This is a work machine that will, regretfully, never have Linux loaded permanently. I have used the BootMed Live-DVD on a couple of laptops and a PC and I've been amazed that I can connect to our network. I used it for a machine that couldn't reboot (parition table got fouled up) to save all of the data on the hard drive by uploading it to a network drive - It was a beautiful moment ...

    I've tried the ubuntu Live-DVD on different machines and it never lets me connect to our network with my credentials. I can see the network shares, but when I enter my credentials, it pops up the screen again to re-enter them, eventually locking out my account.

    I actually just recovered this machine in question (SecureDoc encryption fried it so it wouldn't reboot, but I was able to use the Win 7 x64 DVD to restore it so it would boot back up using "bcdboot c:\Windows" ...

    I was hoping it was a general comparison type of question than particular drivers missing for a particular hardware configuration since it seems to act the same on different devices. It sounds like the steps I took to deactivate IPv6 match your suggestion. I launched Network settings from GUI (No sudo so I'm hoping it considered me to be a Super User/Admin) --> Clicked "Options," then clicked on IPv6 tab and set it to "Ignore" - Although I got the error I described, when I went back into it, it appeared to retain the setting so it sounds like that was successful. Still, no joy after making the change ...

    Thanks again for the insight - I really love the ubuntu interface as the most intuitive one I've seen in my recent shallow step into the Linux pool.

    Re: Ubuntu 12.10 vs. BootMed

    I can't launch ubuntu from the original laptop since I'm in the middle of encryption, but I did launch ubuntu 12.10 (32-bit) from yet another laptop (HP Elitebook 8440p) and captured the info that you requested. Again, I was able to see the shares, but couldn't access them with my network credentials.

    - I'll have to Google to see if there is an equivalent for Ctrl-C and Ctrl-V in ubuntu ...

    Please check in a terminal (CTRL+ALT+T) the outputs of:
    lspci -nnk
    lsusb
    lsmod
    iwconfig
    rfkill list

    After verifying the same issue happens on this different laptop, here is the captured data as requested (Attached files by name of terminal command)

    - Had the same thing happen on this HP 8470p as well

    Please check in a terminal (CTRL+ALT+T) the outputs of:
    lspci -nnk
    lsusb
    lsmod
    iwconfig
    rfkill list

    After verifying the same issue happens on this laptop, here is the captured data from this machine (Uploaded files named after commands).

    Re: Ubuntu 12.10 vs. BootMed

    I'm going to have to stop doing so much testing with this at work ... People are starting to ask why my account keeps getting locked out (We can't unlock ourselves) ... At any rate, I seem to always connect to our network with Bootmed's 32-bit release just by booting up on a wide variety of laptops and PC's, but can never seem to do the same with ubuntu 12.10 (32-bit).

    Clearly, there is a difference in network settings between BootMed's flavor of ubuntu and the "standard" release of ubuntu 12.10. Perhaps they'll work out those differences in the next major release. Thanks for educating me on several commands for network discovery in ubuntu, not to mention leading me into working with the terminal and some "Office" type apps. I really do like the ubuntu interface.



    I'll get the specs on the original laptop in case there is a pattern ...

    Re: Ubuntu 12.10 vs. BootMed

    For the original one, deactivate the N-mode of the driver (bug):
    Code:
    echo "options iwlwifi 11n_disable=1" | sudo tee /etc/modprobe.d/iwlwifi.conf
    sudo modprobe -rfv iwlwifi
    sudo modprobe -v iwlwifi
    This is not permanent, you can type it in every boot-up.

    Re: Ubuntu 12.10 vs. BootMed

    Thanks for walking me through this with all of the code. I've forgotten so much from my UNIX days ...

    I'm reloating Win7 x64 on the HP 8770w laptop now due to it having 2 devices with the larger 500GB drive as device 0 and the 200GB drive as device 1 and the encryption only looks at device 0 and I'm not taking the laptop apart to change where the hard drives plug into the mobo ...

    Anywho, does it look like the same problem exists on either of the other two laptops, which I have access to test now without waiting on Win 7 to install ...

    Also, thanks for the note letting me know that everything is being written into RAM and not the hard drive since these are work machines and I can't mess them up. Your kindness to newbies doesn't go unnoticed ...

    Re: Ubuntu 12.10 vs. BootMed

    Yes, its the same module on the other laptop. If you cant write to disk, the module parameter can be applied directly "live":
    Code:
    sudo modprobe -rfv iwlwifi
    sudo modprobe -v iwlwifi 11n_diable=1
