Linking the machine certificate to something unique like machine-id topic

Hi,

We have 802.1x configured on the wired ports , and we have an NPS authenticating clients via EAP-TLS. My Ubuntu 14.04 LTS laptop is part of AD and has a certificate which was manually requested from our enterprise CA, and i'm able to connect successfully to the network.

We are now thinking if anyone can copy the keypair and certificate from one machine to another and can connect to the network.

1) Is there a way we can make the certificate not exportable like in windows?

2) Also, is there a way to link the certificate with a unique id like “/var/lib/dbus/machine-id” , so that even if one copies the certificate to his machine it wouldn't work?

Thanks

[ubuntu] something killed my ubuntu efi files topic

Installed two days ago ubuntu 14.04.1 dual boot beside win 8.1 on a new notebook. All was running well:
- uefi boot
- secure boot
- grub was working well allowing me to choose
- was able to start to ubuntu
- was able to start to windows

Yesterday I installed OEM updates including a bios update. After that these updates grub is gone. No menu option any more. only boot to windows works. With boot options I'm able to boot /EFI/ubuntu/shim64.efi may anyway windows starts. I also tried to move the EFI ubuntu entry on the first place in BIOS. No way. I've started with LiveCD, mounted the partition with the EFI staff on it and tried to copy the entire file system to a different disk as reference and backup. Copy worked for all files except:
- /EFI/ubuntu/shimx64.efi
- /EFI/ubuntu/grubx64.efi

Both files can't be copied, or better to say only 4K of them. Then the copy process ends with a error message (don't remember, sorry).
So for me it looks like that something has corrupted my two ubuntu efi files!

Does someone has an idea, how to fix those?

[ubuntu] Unable to upgrade 13.04 Ubuntu desktop (Something wicked happened...) topic

Hi all,

I have seen several posts on this problem where people said they are not able to upgrade/update EOL (end of life) version, however i did not see anything specific to my version 13.04.Also none of the other version solutions i saw helped me! :(

$ cat /etc/lsb-release
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=13.04
DISTRIB_CODENAME=raring
DISTRIB_DESCRIPTION="Ubuntu 13.04"

On running "sudo apt-get update"
or
"sudo apt-get upgrade"
or
"sudo apt-get dist-upgrade"

I always get Something wicked happened resolving 'us.old-releases.ubuntu.com:http' (-11 - System error)
Since 13.04 is no longer supported, i have updated the paths in sources.list file with following command:
sudo sed -i -e 's/archive.ubuntu.com\|security.ubuntu.com/old-releases.ubuntu.com/g' /etc/apt/sources.list
but still no success! :(

I also tried removing the locks with both of the below cmds:
sudo rm /var/lib/apt/lists/lock
sudo rm /var/cache/apt/archives/lock

also restarted my machine several times...

I keep on getting above System error messages, and sudo apt-get update always gets stuck at
59% [Connecting to us.old-releases.ubuntu.com] for more than 1hr and then it timeouts! I get some internet problem error, however fact is that i have a very good internet connection. I tried all these the whole day but in vain :(

Note that my Ubuntu had IPv6 enabled. However after all the trial failures i disabled it
$ cat /proc/sys/net/ipv6/conf/all/disable_ipv6
1

However after that too, same problem persists!:(

Can someone please suggest what to do to come to latest supported version of Ubuntu?

[ubuntu] My three bugs that probably have something to do with GNOME 3.... topic

So... I was using Ubuntu 14.10 with my Acer Aspire E 14 laptop and I encountered these three bugs:

1. Ubuntu sometimes couldn't boot. This is not to be confused with the other booting problem(s) where Ubuntu cannot boot at all. Mine was unpredictable: sometimes it booted, but about half to four-fifth of the time my laptop would only display a black screen with a typing-cursor blinking. This happened after GRUB, after you select which OS to boot. When this happened, my only option was to force-power off the laptop and start it all over again, hoping for the half to one-fifth chance that Ubuntu would boot normally.

I do know that some other people have encountered this problem of mine and I saw their posts asking for help, but I found that they got none. The thing is, I guess, this problem was almost always confused with the other booting problem(s) that had something to do with graphics card. Mine, I think, had something to do with GNOME.

2. Ubuntu couldn't power off the laptop. When I shutdown my laptop, Ubuntu would only halt all the processes, but it couldn't power off the laptop so I had to force power off it manually. It was safe, though, since no more proecesses were going, but this still posed a problem: it could neither restart nor hibernate properly.

3. I couldn't right-click with my touchpad, so I had to always use a mouse. It's not the hardware--I tried testing my touchpad settings and when I clicked the button that was supposed to make a right-click, it was read as a left click. I also tried to check the left-handed option where the buttons were inverted and so a right-click would be the primary click, but still I couldn't make a secondary click by clicking the left button of my touchpad. In short, both the left and right buttons of my touchpad were read as primary buttons.

Yesterday I switched to Debian GNOME. The three bugs were gone, but GNOME 3 couldn't load either so the desktop was replaced by something that I guess was GNOME Classic. (I am quite sure that if GNOME 3 could load on my Debian, the three bugs would have manifested themselves again.) Then I switched to Debian KDE. Everything was fine, but I didn't know how to set up my internet on Debian (and lack of internet connection was crippling) so I instantly switched to Fedora, with which I am writing this post right now.

Yet, Fedora uses GNOME 3, and I find the bugs manifesting again, except bug number 1 (or perhaps it just hasn't begin occuring yet, since it occurs by the half to four-fifth chance).

I love Ubuntu more than I do Fedora, but I think I'm not going to switch back until I can certainly fix these problems (especially number 1) or until the bugs are fixed in a future release. So, I wonder if you have some solutions to these problems?

Oh, yea. Last thing, I'm a novice. I had used Ubuntu for some months, but I don't understand more complicated computing terms, so... please answer with simple words, would you?

Thanks!
