I have a laptop running ChromeOS. I'm looking to do some work with Python on AWS but I'm not entirely certain how to SSH to the box. If anyone can give me details on how to connect I'd be grateful. Thanks.

  • Do you have the IP address and an SSH client such as chrome.google.com/webstore/detail/secure-shell/… ?

  • Yes. I can get that information. I haven't assigned an IP to it but I can get one. I can also just use the public name that they assign I believe.

  • If it's a domain name like xx.com or xx.net, you can. If it's "InstanceEC214", you can't. Try downloading that plugin for chrome and see if you can SSH into the server that way.

On your Chromebook:

  1. Download your private key, for example: myKey.pem.

  2. Connect to your EC2 instance from crosh. Press Ctrl+Alt+T to start it, then: 

    crosh>ssh
ssh>user your-user
ssh>host your-host
ssh>key your-key
ssh>connect

    your-user is either:

    • ubuntu if your instance is Ubuntu, or
    • ec2-user if your instance is of Amazon AMI type.


    your-host is a string like this: ec2-number-numbers-numbers-numbers.eu-west-1.compute.amazonaws.com. You'll find that in your AWS console under Running instances, under Public DNS.

    your-key is myKey if you downloaded it like myKey.pem.

  3. Once you are connected to your instance you can work from there (from crosh); or you could make a public key from your private key, in order to connect using secure shell (Secure shell saves your user, host, and keys so you don't have to repeat 'em every time)

  4. Make your public key. On any Linux machine where you have your private myKey.pem, run this:

    ssh-keygen -y -f myKey.pem > myKey.pub

  5. Now install secure shell on your chromebook.

    Run it. Fill user and host. On Identity click Import..., and select BOTH miKey.pem and miKey.pub. Click [ENTER] Connect and you're done.

  • Note you can no longer use ssh through crosh in Chrome OS anymore. They recommend a chrome extension instead.

  • Indeed, ssh is no longer implemented by crosh, meaning it's now impossible to spin up, and connect to, an ec2 instance with only a Chromebook.
