Amazon AWS EC2 Instance Not Connecting - amazon-web-services

I am attempting to create and connect to an Amazon EC2 instance via FidOS. I am following the procedure demonstrated in:
How to Create Amazon AWS EC2 Instance
I logged onto the AWS Console and created a general purpose Ubuntu Server Machine image.
I configured the instance details, added storage, added tags, and configured the Security Group just as in the video.
I clicked "Review and Launch" and created and downloaded the PEM key.
I generated the PPK private key using PuttyGen.
I configured my session using the public DNS in the Host Name field and uploading the private PPK key in the Authorization tab.
After I clicked Open, a terminal window appeared, but then timed out.
I am working on a Windows machine, and trying to create a Ubuntu Linux virtual machine.
Am I missing any steps or doing anything wrong? I would appreciate any help I can get.

The problem was the corporate firewall. It worked just fine when I tried it from another location.

What should be my host name in putty configuration for setting up SSH server?

I am setting up a node.js server on AWS EC2 using putty configurations.There I found to configure putty.I stuck filling the hostname of EC2 in putty.What will be the hostname can anyone Help?
screenshot of putty config :
Note: I have an EC2 instance launched which I have connect with this.
You can give the public ip of your ec2 instance there. which you can find in the aws management console. Attached is the screen-shot for the same.
Let me know if you are not able to connect with this method.
After generating the key .ppk go to SSH-->Auth-->Browse the .ppk key,
save it and load then open.
Log in with ec2-user.
If you want to give a try, we developed an alternative CLI for AWS that makes this much easier: awless.
It should work on Windows too and with awless, you don't need to set either your IP address nor username, just awless ssh i-1234 or awless ssh my-instance-name.
Note that you may also need to add: -i path/to/your/key.pem if the key was not created with awless.

How to connect Mac terminal with EC2 instance

I am using mac terminal and I want to connect my machine with server instance EC2 in aws with SSH. Since I am using Mac OS X is not necessary to use PUTTY. The problem is that when I download the key it is with extension .ppk but when i need to run it on terminal i need to use a command in which i have to use .pem extension . I tried to run it in that way and it said to me permission denied. Can someone help me what to do in this case? Do i have to change the permission or to convert my key from .ppk to .ppm?
You need to know the .pem file folder you download, and then follow steps below:
download the keypair(.pem file)
cd to keypair(.pem file) location (Note that you can use absolute path name for key pair instead)
chmod 400 [your_key_name].pem (Note that to make SSH work, your key must not be publicly viewable. Use this command if needed.)
ssh -i "[your_key_name].pem" ec2-user#[your ec2 dns name]
You will have to convert your "ppk" file to "pem" file follow this steps.

After you convert connect to the instance using the SSH command and converted "pem" file.

Quick answer
Instead of working directly with SSH keys I would consider working with AWS ec2-instance-connect.
It saves you the the management of the SSH keys and is much safer then sharing SSH keys for each EC2 machine between team members.
After authentication with the aws credentials (by referring to a profile in .aws/config file or using environment variables ) you can connect to the instance very easily by providing the instance ID:
./bin/mssh <instance-ID>
Installation of this tool can be done via pip or directly from the github repo.
Additional information
Amazon EC2 Instance Connect provides a simple and secure way to connect to your instances using Secure Shell (SSH).
With EC2 Instance Connect, you use AWS Identity and Access Management (IAM) policies and principles to control SSH access to your instances, removing the need to share and manage SSH keys.
When you connect to an instance using EC2 Instance Connect, the Instance Connect API pushes a one-time-use SSH public key to the instance metadata where it remains for 60 seconds. An IAM policy attached to your IAM user authorizes your IAM user to push the public key to the instance metadata.
The SSH daemon uses AuthorizedKeysCommand and AuthorizedKeysCommandUser, which are configured when Instance Connect is installed, to look up the public key from the instance metadata for authentication, and connects you to the instance.
You can use Instance Connect to connect to your Linux instances using a
browser-based client,
the Amazon EC2 Instance Connect CLI,
or the SSH client of your choice.
(*) Amazon Linux 2 2.0.20190618 or later and Ubuntu 20.04 or later comes preconfigured with EC2 Instance Connect.
For other supported Linux distributions, you must set up Instance Connect for every instance that will support using Instance Connect. This is a one-time requirement for each instance.

Unable to connect Public DNS of AWS

Above image consist of login error of putty and ssh connections.
So I dont know the process of getting connected to my EC2 instances
Question: How to connect to our instances using private_key.ppm and putty.
First of all Download private keys from your aws console so that you can use those keys to looged in to user EC2 instances.
like below
key selection
Fisrt of all decide which public key you wanted to use wheather it is ppm or ppk
Select platform
Then select platform you gonna use in my case i m using Windows. and connectivity software is putty..
Copy required data in the sense your Amazon public DNS .
Copy it from your EC2 instance dashboard.
putty configuration
open up putty ,put ec2-user#public_address Drag your ssh from categories again click on Auth and browse your public key you was just downloaded .

how to create a amazon cloud machine using ec2

I am new to the amazon world.
I have got an amazon ec2 machine with it's public dns and a .pem file . i have connected to the machine using putty by generating a ppk file . now i am able to login to the remote machine using root user. Can someone help me how to create a remote desktop machine or as a cloud machine like the way windows has a rdp feature so that i can install the software. Do i need to install vncserver on it ?. if yes, is there any handy video or documentation which can provide me steps to connect . i have to install appache 2 and mysql on it.
Appreciate your help.
P.S. I can't see any instance on the amzon ec2 which can be created with the machine dns i have got.
Thanks.
1) To see you instance in AWS Console, you need to choose region, where that ec2 server is deployed.
Click on right top menu, there is list of regions there.
2) As we understood, you need to install LAMP Server on that instance.
There are lots of examples how to do it (without GUI, using command line interface).
Find them easily typing how to setup lamp server on ubuntu/centos, depending on your OS.

Unable to RDP to EC2 instance

I created a VM using Hyper-V on my local machine which I can RDP onto fine. I exported the VHDX to VHD and then uploaded it to AWS via the API.
This created a new EC2 instance for me but I cannot connect to it as it has no security keypair associated.
Thus I created a private AMI from the instance and re-instantiated a new EC2 instance from this AMI, setting the keypair in the process to ensure HTTP, RDP etc are permitted. The EC2 instance is running, but when I download teh RDP shortcut if fails to connect. I've tried rebooting the instance several times (as this was one of the suggested solutions on here when I searched) but it hasn't helped.
I also cannot ping any of these instances via the public DNS or private DNS.
Any idea what I'm doing wrong? I'm not even getting as far as the password prompt, its the connectivity is the problem.
Thanks
I had a similar problem - this is the tip from the AWS documentation that helped me solve it:
Verify that the route table for the subnet has a route that sends all traffic
destined outside the VPC (0.0.0.0/0) to the Internet gateway for the VPC
Additional debugging tips for this problem can be found here: Remote Desktop can't connect to the remote computer
The problem is probably the security group configuration attached to the instance. Make sure you have inbound TCP port 3389 permitted to be able to connect via RDP.
in username type:
.\Administrator
....and your decrypted password
See, this is local user. but you dont know real local hostname, that different from public DNS name.
Was helpful for me, hope for you too.
My guess for the reason you aren't getting anywhere has to do with the host certificates.
Be mindful that each computer connecting to the server via RDP needs to have an IAM user in AWS with an X.509 certificate uploaded to their account.
When importing or creating a windows AMI it is best to install and configure the EC2Config service.
The EC2 Config service does the following when you launch the instance:
At initial setup:
Sets the hostname to the private DNS name
Generates and sets a random password on the Administrator account
Initializes and formats the ephemeral disks
Generates and installs the host certificate used for Terminal
Services
Syncs the instance clock with a time server
After initial setup:
Writes the last three entries in the System event log to the Amazon
EC2 console so you can debug startup problems.
Prepares instances for bundling
Also, by default, security groups do not allow you to ping the instances. You must enable ICMP in the security group.
Hope that helps.
EDIT: Here is the link to the 64bit version of the EC2Config Installer
I also had the same problem. This is what I got from EC2.
Public DNS ec2-23-22-109-251.compute-1.amazonaws.com
User name Administrator
Password MyPassword
On the remote desktop, enter the domain and user name as
ec2-23-22-109-251\Administrator
If you paste the password is may not work, try to paste it but reenter the last 1 or 2 characters. Once you get the security certificate prompt accept/install it and your connection should open soon.
This is what worked for me:
Use your cell phone as a "hot spot" - which gives you a static IP address. That worked. Now, I'll need to contact my Internet provider to assign a static IP to my wireless router. Currently, it is spitting out DHCP IP addresses.
UPDATE:
12.7.2016
You need to go to the Security Group, select the Instance, then EDIT the RDP. If you click "MyIP" that should work for those of us working from home. If you are onsite, you may need to put in a custom CIDR.
After rebooting an EC2 instance, I found that I needed to reassociate the Elastic IP address associated with the instance. You click the button below then select the instance and private instance IP address when prompted.
RDP access worked after this step.
After patching Windows 2019 on my server, I couldn't access the instance anymore despite all my working settings didn't change. I used EC2Rescue to fix my issue
