Heyy loved the video but I just have one question... how do you save the key file (EC2Tutorial.pem) into the virtual machine?

[@eliasamsosa1450]

Your browser automatically downloads the key when it is created

[@theloser6212]

Nice explaination bro, thanks btw

[@AshishKumar-bu2di]

Thanks bro ,again a big thanks ❤

[@mubarakharuna6425]

Where did you download the .pem key file from?

[@Heavy1021]

Thank you bro!

[@leoleo-sp1db]

What about adding a visual element over SSH? Could you walk through the steps of doing that? to be able to see your AWS operating systems desktop - thanks good video

[@AwesomeAsh99]

what iterm theme are you using, I've always wanted to be able to highlight the working dir on terminal

[@user-xk6mf2jj3p]

How did you get the .pem file?

[@preethisivaa2881]

thank you stephan

[@Fsdwh]

Thanks it is helpful

[@samus7839]

Thank you

[@jagadeeshbaskaran4881]

does the private key needs to be created when we create the instance?

[@aryankumar87771]

what is the significance of chmod 400 ? is this some kind of a security thing ? will it stop a hacker from reading the pem key, if yes how ?

[@supriyopaul1810]

tnx buddy

[@intimidate123]

If you dont have static IP for ec2 and you reboot server you still have to grab new ip correct?

[@edunwa3679]

Nice!!

[@bhaskarthummala1455]

you just saved me, i was trying to install putty

[@huzaifaali1316]

which key should be pasted in .pem file and how?

[@nathanpetronzio6919]

What terminal do you use for Mac?
I couldn’t quite catch what you said, it sounded like “iturn” ?

[@Hey_ImNishat]

[@aswanivaleti5754]

Hi Stephene Maarek
i am unable to connect my EC2 machine ssh: connect to host IP port 22: Connection timed out
in my security group no issue is there. public IP is not generated while iam creating EC2 machine

[@El.Desarrollador]

I love you!

[@Glitchiedageek]

It’s not letting add the certificate to my keychain. What do I do?

[@chintalaganesh8886]

could you please help me I didn't find .pem file .where we can download ?

[@navinn9744]

Sir give information about community cloud ☁️

[@JairoAndresAmaya]

THANKS !!!1

[@Zerospy]

Where i can find the .PEM?

[@asakzai2022]

plz can anyone tell me how he downloaded the EC2.pem key ?

[@SonnyWest87]

Is this the private or public AWS key you're using in the video? Where did you ssh from? Inside your project? Inside the .ssh folder?

[@emmarose9466]

He's using a private key. Any ssh outlets such as git bash, mobaxterm, Powershell... should work.
A tip is to open your private key folder with a ssh outlet directly so you don't have to worry abt cd into the right file.

[@RidersofChaos673]

hey can you tell me where he download that ec2tutorial.pem file from?@@emmarose9466

[@samedtorun3365]

dude how did you get the .pem file that easily?

[@ismailhunaid7504]

Sir how can I access Ubuntu on AWS ?

[@derrickmkandla6019]

Very frustrated...I am not an experienced developer and I am using iTerm2 on my MAC to try and access my new EC2 instant and everything works fine up to the point where I enter the chmod 0400 line. When I then enter ssh -i with my private key and ec2-user@host command, instead of letting me into my EC2 new instance, I getting a "Permission denied (publickey)" It is as though the chmod 0400 command has changed the Private key to a Public key, making it totally useless.

[@sageleaf8962]

Same here.

[@thiagosrpt]

@@sageleaf8962 same :/

[@ltserge3226]

im having same problem

[@nicumo]

Try ubuntu@host instead of ec2-user@host

[@ltserge3226]

Ok I solved my problem, I was connecting to a second computer, I created the key pair on one computer, and then I tried to use same one on other, I prob suck at explaining but if U tried to do 2 pcs what worked for me was transferring the pem file from one pc to other via messenger

[@Everton_88]

tks

[@navinn9744]

I tried connecting Windows Server through putty , it is working
We connect both Linux, Windows through putty using SSH

[@bellio2095]

HOW DO I DOWNLOAD THE PEM FILE ON MY MAC. I'M clicking download but nothing comes up. No PPK, nothing. I'm in a aws class and I need to download these files to do the lab. Is there a way I can fix it?

[@chintalaganesh8886]

same question
did u find the answer ?

[@CactusJack252]

I did this and still receive permission denied (publickey)

[@fernandogpz]

Wait what, you show how to connect to ssh but not how to generate the pem? :/

[@riccoc.6507]

Where do you download the key file

[@chintalaganesh8886]

same question
did u find the answer ?

[@user-uq9mn7vd1s]

[@herdata_eo4492]

[@williamleke1810]
