AWS —Login to Ubuntu 20

Access Remote Ubuntu via PuTTY SSH Session— AWSSeries # Episode 01

Hi, let’s access our remote ubuntu on the cloud?

In the previous episode, we have deployed ubuntu 20.04 on the cloud.

Now we need to get there inside that Linux distribution.

We had download a key pair that gives us the right to access ubuntu via SSH.

Programs we will need (get it here):

putty - To open a session and access ubuntu instance on the cloud
puttygen - To make the convertion to .pem to .ppk file

Let’s Get Started!

00#step — Open AWS Management Console, click EC2, Instances, and give your instance a name: ubuntu_20_aws

01#step — We will need to change this dynamic IP address to a fixed IP;

02#step — For this go to Elastic IP — Network & Security session (1) and hit the Allocate Elastic IP address button (2).

04#step — Now AWS gives you a fixed IP Address (1);

Fig 5. This is a fixed IP Address. Hurray!

05#step — Let’s associate it with our running ubuntu instance; click Associate Elastic IP address;

06#step — Maintain Instance selected (1) and choose your ubuntu_20_aws instance (2) for the association;

Fig 7. This is how to associate your fixed IP Address with your ubuntu_20_aws instance

07#Step — Return to your EC2 dashboard and you’ll see this IP associated with ubuntu_20_aws instance;

Fig 8. There you have it: a fixed IP address. Touche!

08#Step — Now open puttygen, locate tour ubuntu_20_server_keys.pem from the previous episode and load it with the same name, now with the extension .ppk (putty private key);

09#Step — Now click ok (1), and hit Save private key button (2);

10#Step — You will end with ubuntu_20_server_keys.ppk file;

11#Step — Now open PuTTY, SSH configuration, in Auth save the location of your recently saved .ppk key;

Fig 11. Configuring PuTTY session; first Auth, load your private key .ppk file

12#Step — Go to Connection > Data, save ubuntu as Auto-login username;

13#Step — Now, finally, save the Session putting Host Name (or IP address) as your fixed IP for your Ubuntu instance running remotely;

Fig 13. Save the session

14#Step — Now Putty opens an alert window, saying that a NIC interface was never accessed and asking if everything is alright. Hit Yes;

Fig 14. And you are inside ubuntu instance

15#Step — Now ubuntu is under your command!

Fig 15. Congratulations! Your remote ubuntu is under your command!

That’s all for now!
