Thanks for your videos, they're great! I have a question. Why use a NAT gateway when you already have a public route table for the public subnet?
@AWSCloudBytes
@AWSCloudBytes Жыл бұрын
NAT Gateway is used by private instance for communicating to internet, you may be running software's on private subnet EC2 instance which will need updates. The safest way to get it using NAT gateway, which will allow traffic to flow from your VPC to internet and get the responses back but it will not allow traffic to be initiated from the internet to these machines. Public subnet EC2 is just an example of a Jump Box which doesn't need NAT Gateway for any public internet access as its route table is already having a route to internet gateway. Any one having SSH credentials if SSH is enabled on the EC2 instance and routes are open for incoming IP address can perform an SSH on EC2 instance. Generally you lock down IPs that can perform SSH request to your public machines. I hope this helps.

Hi Sir, Good Morning, can enable VPC endpoints for S3 for cross accounts ? let say we have one internal account and multiple external accounts and now these external accounts sends the data to internal account, so can follow the VPC endpoint steps or over internet only possible ? Please help

@@AWSCloudBytes Thank you So much , this is great help to me. my case is one internal account and multiple external accounts will transfer the data to this single internal account. so for each external account i should go with separate VPC endpoint correct ?

Apologies Balaji for late response, KZbin hides replied comments so if there is an existing comment with a new response it is not visible. To answer your question yes it will be a good approach, it will give you fine grained access control, isolation and security, and you can do performance optimizations. The only caveat is the cost and maintenance. I will suggest to check for VPC endpoint charges.

How the s3 showed up in public instance? While creating the s3 bucket it blocked all access right?
@AWSCloudBytes
@AWSCloudBytes Жыл бұрын
To access the S3 from public EC2 instance, the following things will be required. You are right the S3 bucket created in lab had blocked all public access, but not access from a trusted entity. Accessing Amazon S3 from a public jump box in AWS involves a few steps. Here's a general guide: 1. Jump Box/Public EC2 Setup: - Launch an EC2 instance to serve as your jump box in a public subnet. - Ensure that the security group associated with the jump box allows inbound SSH traffic (port 22) from your IP address or a specific range of IP addresses. 2. IAM Role Setup: - Create an IAM role that has the necessary permissions to access the S3 bucket. Attach policies like `AmazonS3ReadOnlyAccess` if you only need read access. Customize the policies based on your requirements. - While creating the IAM role, make sure to specify the EC2 instance as the trusted entity that can assume this role. 3. Attach IAM Role to the Jump Box: - Attach the IAM role you created to your EC2 instance (jump box). You can do this during the instance launch or by modifying the instance details. 4. SSH into the Jump Box: - Connect to your jump box using SSH. Use the private key associated with the key pair when launching the EC2 instance. 5. Configure AWS CLI: - Install the AWS Command Line Interface (AWS CLI) on your jump box if it's not already installed. - Run `aws configure` and enter the IAM user's access key, secret key, default region, and output format. 6. Access S3 from the Jump Box: - Once the IAM role is attached and the AWS CLI is configured, you can use AWS CLI commands to interact with S3. For example: aws s3 ls s3://your-bucket-name It's a good practice to use IAM roles with the principle of least privilege, granting only the permissions necessary for the task at hand. If you need write access or more specific permissions, adjust the IAM policies accordingly. Also, consider setting up AWS Systems Manager Session Manager as an alternative to direct SSH access, as it provides a secure and auditable way to access your EC2 instances without exposing SSH ports to the internet.

can you tell how you access in private instance through terminal because i cant do that and from where you bring that password and how you created it when i tried same as your command ssh cloud_user@public ip it shows permission denied

Apologies for late response. In order to reach private instance you will have to first ssh to the public facing instance. This is also called jump box or bastion host. Once you ssh to this public ec2 instance you can then use the private IP of the ec2 in private subnet to ssh. As you have ssh on public instance you are in the network due to which access to private instance is possible.

Hi how to create private ec2 without public ip
@AWSCloudBytes
@AWSCloudBytes Жыл бұрын
To create a private EC2 instance without a public IP in AWS, you can follow these steps: Launch a VPC (Virtual Private Cloud): If you don't have a VPC already, create a new one. Ensure that the VPC has private subnets (subnets without internet gateways) where you want to deploy your private EC2 instance. Create a Security Group: Create a security group that allows inbound and outbound traffic as per your requirements. This security group will be associated with your private EC2 instance. Launch the EC2 instance: During the EC2 instance launch process, you need to select the appropriate VPC and subnet that you want to place the instance in. Choose an Amazon Machine Image (AMI): Select the desired operating system and software configuration for your instance. Configure Instance Details: In the "Configure Instance Details" section, you need to: Choose the private subnet from the "Network" dropdown. Optionally, you can specify a private IP address or let AWS assign one from the subnet's IP range. Add Storage: Configure the instance storage as per your requirements. Add Tags (optional): Assign tags to the instance for better management and organization. Configure Security Group: Select the security group you created earlier to associate with this instance. Review: Review your settings and make sure everything is correct. Launch the instance: Finally, click "Launch" to create the private EC2 instance without a public IP. After launching the private EC2 instance, it will not have a public IP address and will be accessible only from within the private subnet or through other resources within the VPC with appropriate access permissions. If you need to access the instance, you can use bastion hosts or VPN solutions to connect securely to the private subnet.

To SSH into an EC2 instance without a password, you can use SSH key-based authentication. Here's how to set it up: Create a key pair on your local machine: ssh-keygen -t rsa This will create a public and private key pair in ~/.ssh/id_rsa and ~/.ssh/id_rsa.pub. Log in to your EC2 instance using the public key you just generated: ssh -i ~/.ssh/id_rsa.pub ec2-user@ Once logged in, create a .ssh directory if it doesn't exist: mkdir -p ~/.ssh Copy the public key from your local machine to the EC2 instance: scp ~/.ssh/id_rsa.pub ec2-user@:~/.ssh/authorized_keys Set the correct permissions on the authorized_keys file: chmod 600 ~/.ssh/authorized_keys Log out of the instance. Log back in to the instance using your private key: ssh -i ~/.ssh/id_rsa ec2-user@ You should now be able to SSH into your EC2 instance without a password using the private key. ======== To use Password=========== By default, EC2 instances on Amazon Web Services (AWS) are not set up with a password for logging in as the root user via SSH. Instead, you would typically use SSH key-based authentication to log in securely. However, if you need to set a password for the root user, you can follow these steps: Log in to your EC2 instance using SSH key-based authentication. Once logged in, run the sudo passwd root command to set a password for the root user. Enter a new password when prompted, then confirm it. Log out of the instance. Log back in to the instance using the root username and the new password you just set. Note that setting a password for the root user can be a security risk if not done properly, as it opens up the possibility of brute-force attacks and other security issues. It is generally recommended to use SSH key-based authentication instead for increased security.

Where did this password come from? I can't find it.

I was using a linux instance where password authentication was set to true. Due to this I had a password. It is not recommended to use password though so you should use the key pair. You would have created a key pair which can be copied on the Jump Host/Public machine you perform first SSH on and use this key to perform SSH to private instance. Let me know if you need any other information.
