U2f yubikey - setup process confusing
 

hi. i am trying to setup my fb account for 2 factor authorization using my U2F blue key. for using linux with the key, the following instructions are below. i read something that said something about using a command line. does anyone know how to use a command line to do this? if not, can someone help me to understand the instructions below?

==================================================================================================== ========================
To set up your Linux system for U2F, follow steps 1-5:

1--- If you have a Security Key by Yubico (blue color), U2F is enabled by default (only U2F mode is supported on this product).
2--- Go to https://github.com/Yubico/libu2f-hos...r/70-u2f.rules and
download or create a copy of the file named 70-u2f.rules into the Linux directory:
/etc/udev/rules.d/
3--- If this file is already there, ensure that the content looks like the one provided on github.com/Yubico (link above).
4--- Note: If your version of UDEV is lower than 188,
use the rules at https://github.com/Yubico/libu2f-hos...-old-u2f.rules instead.
5--- Save your file, and then reboot your system.

I am stuck at the 2nd step. i go to that page and i'm assuming that lines "1-56" are the file. if i copy the file (since i don't see a download link for it unless the blue hyperlink at the top is it), how do i put it into a directory called "/etc/udev/rules.d/" ? how do i create that directory?

cheers

Click the "raw" button, then use your browser option to "Save file as ..." - use the name given and make sure the filetype is "plain text" or txt, something like that.
Then you can copy the file to /etc/udev/rules.d/ (which should already exist).

thanks, but i don't understand........ where is there a "raw" button? also, "can copy the file to /etc/udev/rules.d/ (which should already exist)." where does this already exist - i have no idea.

thanks for trying but i need further clarification.

ok. i found raw and saved it as a .txt. but i don't understand: /etc/udev/rules.d/ (which should already exist).

where does it exist?
cheers

when i put that in the directory url, i get a blank page that opens. but i am not able to paste it there..... i don't know if that is where it is suppose to go, but if yes, it won't paste.

You haven't posted your distro (Ubuntu, Mint, ... whatever) or your Desktop Environment (gnome, Cinnamon, ....whatever) so we can only be general.
/etc/udev/rules.d is a directory (think folder) that is owned by root user - him be god, however you visualise that. You can pretend to be god for a short while.
Open a terminal (like an old DOS session in windows) - try the Windows key, bottom left and type in terminal - enter this code, you will be asked for your password.List that dir from your GUI filemanager and see if t file is there - if not post back, and we'll try it slowly.

i switched where they key was to the hubs where my firewall and browser are - i suspect that is where it should be in the first place, i'm guessing........

find: ‘70-u2f.rules’: No such file or directory

incidentally, i downloaded a copy of both "old-u2f" rules and the "r/70-u2f"

any suggestions???

OK, let's see what you actually have on that machine.

find . -iname "*-u2f*" 2>/dev/null
./Desktop/70-u2f.rules.txt
./Desktop/70-old-u2f.rules.txt
NAME@NAME:~$ ls /etc/udev/rules.d

OK, let's just copy it over - then make sure it's there, then you should be able to reboot.

thx.

~# sudo cp ~/Desktop/70-u2f.rules.txt /etc/udev/rules.d/70-u2f.rules
root@NAME:~# ls /etc/udev/rules.d/

what's next?
