Aws Open For Write: Permission Denied Filezilla - Tuts Make

If you have aws instance virtual web server and it is running. Also want to transfer/upload files on ec2 aws web server using filezilla. So, you have Filezilla connected to the AWS server but when you try to move the files from my local machine to the /var/www/html directory on apache 2 aws, it displays permission denied.

You can see Amazon AWS Filezilla transfer permission denied error on following image:

So, in this post, we will show you simple way to enable the permission of your aws apache 2 ubuntu user. And you can easily transfer/upload file using filezilla on amazon aws apache 2 ubuntu web server without error.

Solution 1 – AWS Ubuntu – Enable File Transfer permission denied Filezilla

First of all, you need to connect your aws ec2 instance from ssh terminal. If you are new to connect aws ec2 instance with windows, ubuntu and mac system. So you can read this tutorial “How to Connect to ec2 Instance From Putty and SSH Terminal” to connect your ec2 instance from ssh. Otherwise you can see the how to enable write for permission denied.

Now, you can use the following command to enable write access to the public web directory (/var/www/html).

Important note, different types of users contain different user names for the Amazon AWS instance virtual web server. You can see the following table:

• Amazon – ec2-user
• Centos – centos
• Debian – admin or root
• Fedora – ec2-user
• RHEL – ec2-user or root
• SUSE – ec2-user or root
• Ubuntu – ubuntu or root

Now, connect your aws instance with ssh terminal. Then type the following command:

Aws centOs User

sudo chown -R centos:centos /var/www/html

sudo chmod -R 755 /var/www/html

Aws Ubuntu User

sudo chown -R ubuntu:ubuntu /var/www/html

sudo chmod -R 755 /var/www/html

AWS Amazon ami User

sudo chown -R ec2-user:ec2-user /var/www/html

sudo chmod -R 755 /var/www/html

After that, type the following command on your ssh terminal:

chmod -R 755 /var/www/html

Thanks for reading this post, we hope this post is helpful for as to enable write permission on /var/www/html directory in aws virtual web server.

AWS Cost Allocation Tags and Cost Reduction

Bob had just arrived in the office for his first day of work as the newly hired chief technical officer when he was called into a conference room by the president, Martha, who immediately introduced him to the head of accounting, Amanda. They exchanged pleasantries, and then Martha got right down to business:

“Bob, we have several teams here developing software applications on Amazon and our bill is very high. We think it’s unnecessarily high, and we’d like you to look into it and bring it under control.”

Martha placed a screenshot of the Amazon Web Services (AWS) billing report on the table and pointed to it.

“This is a problem for us: We don’t know what we’re spending this money on, and we need to see more detail.”

Amanda chimed in, “Bob, look, we have financial dimensions that we use for reporting purposes, and I can provide you with some guidance regarding some information we’d really like to see such that the reports that are ultimately produced mirror these dimensions — if you can do this, it would really help us internally.”

“Bob, we can’t stress how important this is right now. These projects are becoming very expensive for our business,” Martha reiterated.

“How many projects do we have?” Bob inquired.

“We have four projects in total: two in the aviation division and two in the energy division. If it matters, the aviation division has 75 developers and the energy division has 25 developers,” the CEO responded.

Bob understood the problem and responded, “I’ll see what I can do and have some ideas. I might not be able to give you retrospective insight, but going forward, we should be able to get a better idea of what’s going on and start to bring the cost down.”

The meeting ended with Bob heading to find his desk. Cost allocation tags should help us, he thought to himself as he looked for someone who might know where his office is.

How To Unite AWS KMS with Serverless Application Model (SAM)

The Basics

AWS KMS is a Key Management Service that let you create Cryptographic keys that you can use to encrypt and decrypt data and also other keys. You can read more about it here.

Important points about Keys

Please note that the customer master keys(CMK) generated can only be used to encrypt small amount of data like passwords, RSA key. You can use AWS KMS CMKs to generate, encrypt, and decrypt data keys. However, AWS KMS does not store, manage, or track your data keys, or perform cryptographic operations with data keys.

You must use and manage data keys outside of AWS KMS. KMS API uses AWS KMS CMK in the encryption operations and they cannot accept more than 4 KB (4096 bytes) of data. To encrypt application data, use the server-side encryption features of an AWS service, or a client-side encryption library, such as the AWS Encryption SDK or the Amazon S3 encryption client.

Scenario

We want to create signup and login forms for a website.

Passwords should be encrypted and stored in DynamoDB database.

What do we need?

1. KMS key to encrypt and decrypt data
2. DynamoDB table to store password.
3. Lambda functions & APIs to process Login and Sign up forms.
4. Sign up/ Login forms in HTML.

Lets Implement it as Serverless Application Model (SAM)!

Lets first create the Key that we will use to encrypt and decrypt password.

KmsKey:
    Type: AWS::KMS::Key
    Properties: 
      Description: CMK for encrypting and decrypting
      KeyPolicy:
        Version: '2012-10-17'
        Id: key-default-1
        Statement:
        - Sid: Enable IAM User Permissions
          Effect: Allow
          Principal:
            AWS: !Sub arn:aws:iam::${AWS::AccountId}:root
          Action: kms:*
          Resource: '*'
        - Sid: Allow administration of the key
          Effect: Allow
          Principal:
            AWS: !Sub arn:aws:iam::${AWS::AccountId}:user/${KeyAdmin}
          Action:
          - kms:Create*
          - kms:Describe*
          - kms:Enable*
          - kms:List*
          - kms:Put*
          - kms:Update*
          - kms:Revoke*
          - kms:Disable*
          - kms:Get*
          - kms:Delete*
          - kms:ScheduleKeyDeletion
          - kms:CancelKeyDeletion
          Resource: '*'
        - Sid: Allow use of the key
          Effect: Allow
          Principal:
            AWS: !Sub arn:aws:iam::${AWS::AccountId}:user/${KeyUser}
          Action:
          - kms:DescribeKey
          - kms:Encrypt
          - kms:Decrypt
          - kms:ReEncrypt*
          - kms:GenerateDataKey
          - kms:GenerateDataKeyWithoutPlaintext
          Resource: '*'

The important thing in above snippet is the KeyPolicy. KMS requires a Key Administrator and Key User. As a best practice your Key Administrator and Key User should be 2 separate user in your Organisation. We are allowing all permissions to the root users.

So if your key Administrator leaves the organisation, the root user will be able to delete this key. As you can see **KeyAdmin **can manage the key but not use it and KeyUser can only use the key. ${KeyAdmin} and **${KeyUser} **are parameters in the SAM template.

You would be asked to provide values for these parameters during SAM Deploy.
