SSH using Chrome Secure Shell app with SSH identity (private key and public key)

-
It's something I keep using a lot!

The Chrome's Secure Shell app is wonderful and is handy for people who want to use the chrome's tab for connecting to the remote server.

So here it is:
  1. Install Secure Shell from the chrome web app store.
  2. Once added, open the app and select "[New Connection]":
  3. Enter the details:
  4. Remember to change the permission of the pem file, using the following command: 
    chmod 400 mykey.pem
  5. Generate the public key from the private key: 
    ssh-keygen -y -f mykey.pem > mykey.pub
  6. RENAME the private key (.pem) file to remove the extension of the private key (The most Important :P). Otherwise, the files won't be accepted by the plugin: 
    mv mykey.pem mykey
  7. Click on the "Import" button beside the Identity in that screen and select both the files:


In case you want to Reset the known_hosts then do the following:

  • Open the Developers Tools
  • Go to Console and type: term_.command.removeAllKnownHosts()


That's it.
You are good to go.

This is my usual way to connect to Amazon EC2 instances.
In case you face any difficulties, do feel free to add a comment, or even recommend any changes. :)

    This is exactly what I was looking for. It wasn't working for me because I was only selecting the private key.
    Thanks a lot!

    I am having a problem connecting to my EC2 instance using the SSH extension in Chrome, I can not import my private key. I do not have a public key, and I tried to use the ssh keygen command to create a public key and that did not work. I removed the extension on the file...as a matter of fact I copied the data that makes the private key and create a new file in Notepad and pasted that data into the new file and made sure that the file did not have a extension. What am I doing wrong ? Thanks in advance !

      Hi,
      You need to remove extension of the private key file once you generate the public key. As well ensure your file permission is set to 400 (Only file owner can read it)

      Are you sure the machine is reachable with port 22 being open?
      Check whether the port is open for that machine using:
      telnet 3.8.125.80 22

    Does the Public Key have to be saved as a .pub file? This is saving as a Microsoft Publisher and prevents my access. Is there a workaround?

      As much I can state, the .pub file a way to tell it's public key in case of SSH console. What you can try once is naming the .pub as some other extension, like .pubk and try to import. If that does not work out, then what you can do is for a brief time uninstall Microsoft Publisher and re-install once done.

    Quick Question: I'd like to start a new EC2 Instance, but also like to start over and generate and use a totally different key pair how would I go about doing that? I attempted to do this, but the Shell App will not allow a new upload of the new files. It's simply the old key and [default] in the dropdown menu of the Identity Field

    I saw at the bottom of the blog post you mention a way to reset the app, but where are the Developer Tools located? I don't see that in the options section of the shell app.

    Thank you greatly!

    Hi .I would just like to post a question here:

    Why are we exactly removing the private key extension(.pem) before importing it in SSH console. As far as I understand, private key is private and should not be shared with the SSH client .But we are uploading both the public key and the private(after removing the extension).Not sure why? Thanks in advance

      Hi,

      Just to clarify there is no need of removing the private key.

    This doesn't even make any sense... what .pem file? Where is it stored? You mentioned nothing about it other than its name, which doesn't happen to exist on my computer

      I figured out a way to do this and am connecting with a public/priv keypair generated on the linux server and copied over... I still have no idea what this article is talking about with the .pem file.

      I just logged into the linux server, went to a random directory and ran
      `ssh-keygen -t rsa -f ./id_rsa -q -N "" && cat ./id_rsa.pub >> $HOME/authorized_keys`
      which generates both the private and public key files and adds the public key to the authorized_keys file. Then copied them to a random directory on windows using winscp, and deleted them from server. Finally I logged out of the linux server, and in the secure shell app clicked import and selected both keys. Immediately was able to log in without password prompt, no hastle or dealing with mystery .pem files.

      correction: command is
      `ssh-keygen -t rsa -f ./id_rsa -q -N "" && cat ./id_rsa.pub >> $HOME/.ssh/authorized_keys`

    noticed a bug where it wouldn't take my credentials unless i added an empty line to the bottom of each file.. Might help if someone else is having the same issue.

    Are the two files moved to ~/.ssh on the Chromebook? If so, how can I access them in the future?

NGinx + Gunicorn + Flask-SocketIO based deployment.

-
It's been a long time I wrote a blog post!. Recently I realized I should at least write about my unwarranted account of solving problems which were hard, to just get some information online. So this post provides the details we need to know how to deploy the Flask-SocketIO app using Gunicorn and NGinx. Here are the links for NGinx , it is a web server with a focus on high concurrency, performance and low memory usage. Gunicorn 'Green Unicorn' is a Python WSGI HTTP Server for UNIX and Flask-SocketIO  gives Flask applications access to low latency bi-directional communications between the clients and the server. The client-side application can use the SocketIO Javascript library or any compatible client to establish a permanent connection to the server.  Version's I used: Nginx : 1.6.0 (Websocket support in Nginx was introduced in version 1.4 and above) Gunicorn : 17.5 Flask-SocketIO : 0.6.0 If you go through the document's of the tools, you will com
