@christianbueno The GUI is a bit different yes. I edited my answer and added the new NM GUI. Check it.

2017-06-25 05:35:09 -0600 edited answer How do I change my DNS settings?

If you are using Fedora 20 with the pre-installed GNOME environment, equals to GNOME network manager.

Search and find network connection application and open it. Then, find your connection in the list and click edit. Go to ipv4 settings select Automatic (DHCP) addresses only as the method and write manually the DNS servers you want. Here we are using Google OpenDNS servers 8.8.8.8 and 8.8.8.4, you can add multiple addresses by separating them with a comma.

After you save the changes, restart network manager.

sudo systemctl restart NetworkManager

Now if you look at resolv.conf, you should see only the DNS addresses you added.

cat /etc/resolv.conf

At Fedora 25-26 the Network Manager GUI is a bit different but still, the same solution applies.

2016-04-13 03:28:06 -0600 marked best answer How to enable SNA acceleration method for Intel cards in Fedora 20 ?

There are two major acceleration methods for Intel cards. UXA and SNA. The later is newer and gives some advantages. You can see various of benchmarks over the Internet. Example : Openbenchmarking.org

I recently installed Fedora 20 and I saw that the UXA acceleration method is enabled by default. I have an Intel card that supports the SNA acceleration method and I know that Intel driver that is included in Fedora 20 does support this method.

How to enable the SNA acceleration method for my Intel card in Fedora 20 ? Do I have to install any additional software and what configuration must be done ?

If this is the answer to your question/problem, please accept it as the correct answer.

2015-07-27 19:52:12 -0600 edited answer Why i cant use one public key to athorize 2 users by ssh?

Thanks for @stephenw, as He make me read official documentation. i've found restrictions:

"If you complete the steps as root, only root will be able to use the keys."

So, if you create key-pair for root - you wont be able to login as normal user

2015-07-27 19:51:45 -0600 edited answer Why i cant use one public key to athorize 2 users by ssh?

Maybe it is just a matter of putting the key in a global config file.

Quote from Fedora 22 SysAdmin Guide: An OpenSSH Configuration

/etc/ssh/ssh_config The default SSH client configuration file. Note that it is overridden by ~/.ssh/config if it exists.

2015-07-27 19:45:40 -0600 answered a question Fedora system detect usb, but it doesn't work in fedora softwares (please read details to understand)

Have you tried to first unmount the usb (not completely remove it or eject it, but unmount) and try again with such programs ?

Virtualbox is a special case where you have to have installed the VirtualBox Extension Pack in order for USBs to be recognized and work properly.

Also, I would try with an Official Fedora (or Spin) distribution.

Might be better to report this problem in Korora's support desk.

You have to know that unetbootin is not recommended anymore. It is (almost) deprecated and creates various problems especially on UEFI systems.

Please read on Wiki as of how to create a Fedora Live USB:

https://fedoraproject.org/wiki/How_to...

Because your system (nautilus, disks ...other programs) detect the USB correctly and you can read the content, also write on it, I don't see any problem related to Operating System or/and USB stick(as hardware).

Probably this is related to these specific programs which you mentioned.

I did it until this problem happend, I don't know why. The issue is: The operating system detects my usb nevertheless fedora live usb creator and unetbooting doesn't detect it (also virtualbox)

USB detected img : See 4gb drive

USB is not detected img :

Thanks in advance

2015-07-27 03:08:01 -0600 answered a question Copy & Paste in the gnome-terminal

If you are using GNOME on Wayland, this is a known bug:

1) https://bugzilla.redhat.com/show_bug....

2) https://bugzilla.redhat.com/show_bug....

If you are not using Wayland, then maybe the lines you are trying to paste are not in a clear/clean text format ? Try to paste these lines first in an editor (eg gedit) then copy from there and try to paste into gnome-terminal.

As an alternative try to use the shortcut Ctrl+Shift+V (for Paste into terminal from buffer) or Ctrl+Shift+C (to copy from terminal into buffer).

2015-07-26 21:26:58 -0600 marked best answer How to enable `samba share` for a specific directory?

I want to share a specific directory with the machines on my local network. Samba is the preferred protocol, because of the global OS support. (Windows included).

What I have to do in order to enable sharing in Fedora 20? Do I have to install any additional software? Do I have to do any special configuration ?

2015-07-26 16:34:43 -0600 commented question Fedora 22 > Failed to authenticate Password!! [Solved]

You didn't follow the commands exactly as far as I can see. In techmint tutorial they say

Create an User for Virtualbox as:

usermod -G vboxusers -a user_name

passwd user_name

except that this is wrong, I mean, with usermod -G vboxusers -a user_name you don't create a new user but you add your user (existing user) to vboxusers group and there is no need to execute the second command passwd. You didn't execute this command, but instead usermod -a -G vboxusers root.admin , what is this root.admin ? Also, what is the exact problem you have right now? Can you login to the system?

2015-07-26 16:22:54 -0600 edited question Fedora 22 > Failed to authenticate Password!! [Solved]

After Entering this command password failed to authenticate i cant mount my drives and user account unlock failed to authenticate password.

usermod -a -G vboxusers user_name
passwd user_name

Terminal

su
usermod -a -G vboxusers root.admin
passwd user_name root.admin
new pass 12345
retype pass 12345
