0.08 -> hi youtube family my name is Vicky and in today's
video we are going to learn how to enable password
5.12 -> authentication on amazon linux machine, here we
need to understand one thing when we are creating
10.16 -> a machine on the amazon what will happen is we are
selecting the ami which is provided by the amazon
16.08 -> or you know we can choose the ami which
is provided in the marketplace or which
21.2 -> is provided by some other users so these ami are
already pre-configured we are not installing the
28.16 -> operating system on all those things right
operating system is already installed along
32.08 -> with that some other settings as well so whenever
we are creating a machine password is not enable
37.6 -> for any of the user to log in, we always have to
log in with the key pair so that is the reason
43.12 -> at the time of creation of the machine the last
step is where we need to select the key pair
47.44 -> and when we try to log into the amazon linux
machine we need to log in with the keypair
53.04 -> in this video i will explain you
how you can enable the password
56.88 -> for the user how you can create the user and
how you can enable the password for that user
62.72 -> let's go to the demo here i am in my aws console
and here i have couple of machines which are
69.04 -> already created and these machines are for the
linux let me select one of the machine and let
74.56 -> me login to that machine so let me grab the public
ip of that machine and let me go to my terminal
82.56 -> and i need to go to that location
where i have downloaded my key pair so
91.28 -> this is the default username ec2 dash
user and then the ip address okay
98.32 -> i'm able to log into my machine let's wait for
it to login yes now i'm able to login let's
104.16 -> suppose i need to log in with the password so
first what i need to do is i need to enable the
108.88 -> password for this user for the ec2 user so how
we can enable the password for that we need to
114.8 -> use the command sudo password and then
the username even if we are not going to
119.76 -> give the username it is going to pick
this username but it is good if you
123.52 -> keep the username now it is asking me to enter the
password so here i have entered the password now
129.28 -> let me exit from here and let's try to login with
the password ec2 - user @ whatever the ip address,
140.32 -> now here when i try to log in with the password
it is not going to give me that option to enter
144.48 -> the password and it will come up with the
error message permission deny public key
149.04 -> gss api key index something like this now
how to correct this thing for that what
154.64 -> we need to do is we need to login back to
our machine with the help of the key pair
161.52 -> okay now what we need to do is we need to
go to cd etc ssh folder now here we have
173.68 -> one of the file that is ssh config this is a
configuration file this is very important file
179.6 -> so make sure once you have knowledge on this
file then only you are going to edit this file
184.24 -> it is always good to take a backup of this
file once you know you are going to do some
188.56 -> changes or something let me login to this so
sudo nano sshd config here if i scroll down
204.16 -> here if we look at this thing
password authentication no
207.92 -> so this is something we need to enable so what
we need to do is we need to comment this section
212.72 -> and we need to uncomment this one password
authentication yes let me save this thing
222 -> the second thing which i need to do is
i need to restart the service as well
225.6 -> and which service we need to restart
that is the ssh config so sudo service
232.48 -> sshd restart we are done let
me exit now let me try to login
244.48 -> here i am getting the option to enter the password
so the password was one two three let me enter
249.36 -> that and let me try to log in i'm able to log
in successfully with the password now okay so
257.44 -> this is the way you can enable the password
authentication on your amazon linux machine
263.28 -> i hope you like this video if you like this
