FTP Server : Vsftpd Over SSL/TLS

 Enable SSL/TLS for Vsftpd to use secure FTP connections.

[1]. Create self-signed certificates.

But if you use valid certificates like from Let's Encrypt or others, you don't need to create this one.

[root@www ~]# cd /etc/pki/tls/certs

[root@www certs]# openssl req -x509 -nodes -newkey rsa:2048 -keyout /etc/pki/tls/certs/vsftpd.pem -out /etc/pki/tls/certs/vsftpd.pem

/certs/vsftpd.pem -out /etc/pki/tls/certs/vsftpd.pem a:2048 -keyout /etc/pki/tls/

Generating a RSA private key

........................+++++

..................+++++

writing new private key to '/etc/pki/tls/certs/vsftpd.pem'

-----

You are about to be asked to enter information that will be incorporated

into your certificate request.

What you are about to enter is what is called a Distinguished Name or a DN.

There are quite a few fields but you can leave some blank

For some fields there will be a default value,

If you enter '.', the field will be left blank.

-----

Country Name (2 letter code) [XX]:JP   # country code

State or Province Name (full name) []:Hiroshima    # State

Locality Name (eg, city) [Default City]:Hiroshima  # city

Organization Name (eg, company) [Default Company Ltd]:GTS  # company

Organizational Unit Name (eg, section) []:Server World     # department

Common Name (eg, your name or your server's hostname) []:www.srv.world  # server's FQDN

Email Address []:root@srv.world   # admin's email


[root@www certs]# chmod 600 vsftpd.pem

[2]. Configure Vsftpd. Configure basic settings before it, refer to here.

[root@www ~]# vi /etc/vsftpd/vsftpd.conf

# add to the end : enable SSL/TLS

rsa_cert_file=/etc/pki/tls/certs/vsftpd.pem

ssl_enable=YES

force_local_data_ssl=YES

force_local_logins_ssl=YES

[root@www ~]# systemctl restart vsftpd

FTP Client : CentOS

 

Configure FTP Client to use FTPS connection on CentOS.

[3]. Install FTP Client first, and configure like follows.

[redhat@dlp ~]$ vi ~/.lftprc

# create new

set ftp:ssl-auth TLS

set ftp:ssl-force true

set ftp:ssl-protect-list yes

set ftp:ssl-protect-data yes

set ftp:ssl-protect-fxp yes

set ssl:verify-certificate no

[redhat@dlp ~]$ lftp -u cent www.srv.world

Password:

lftp cent@www.srv.world:~>

Lambda Function with Amazon SNS

  Amazon SNS is a service used for push notification. In this chapter, we will explain working of AWS Lambda and Amazon SNS with the help of an example where will perform the following actions − Create Topic in SNS Service and use AWS Lambda Add Topics to CloudWatch Send SNS text message on phone number given. Requisites To create Topic in SNS Service and use AWS Lambda Add Topics to CloudWatch, we need not follow the steps given below − Create Topic in SNS Create Role for permission in IAM Create AWS Lambda Function Publish to topic to activate trigger Check the message details in CloudWatch service. To send SNS text message on phone number given, we need to do the following − Add code in AWS Lambda to send message to your phone. Example In this example, we will create a topic in SNS. When details are entered in the topic to publish, AWS Lambda is triggered. The topic details are logged in CloudWatch and a message is sent on phone by AWS Lambda. Here is a basic block diagram which...

Building the Lambda Function

AWS Lambda function executes a code when it is invoked. This chapter discusses all these steps involved in the life cycle of AWS Lambda function in detail. Steps for Building a Lambda function The lifecycle of Lambda function includes four necessary steps − Authoring Deploying Monitoring Troubleshooting Authoring Lambda Code AWS Lambda function code can be written in following languages − NodeJS Java, Python C# Go. We can write code for AWS Lambda using the AWS console, AWS CLI, from Eclipse IDE, from Visual Studio IDE, serverless framework etc. The following table shows a list of languages and the different tools and IDE that can be used to write the Lambda function −   NodeJS :  AWS Lambda Console | Visual Studio IDE Java : Eclipse IDE Python : AWS Lambda Console C# : Visual Studio IDE | .NET core Go : AWS Lambda Console Deploying Lambda Code Once you decide the language you want to write the Lambda function, there are two ways to deploy the code − Directly write the code in...

Lambda Function with Amazon DynamoDB

DynamoDB can trigger AWS Lambda when the data in added to the tables, updated or deleted. In this chapter, we will work on a simple example that will add items to the DynamoDB table and AWS Lambda which will read the data and send mail with the data added. Requisites To use Amazon DB and AWS Lambda, we need to follow the steps as shown below − Create a table in DynamoDB with primary key Create a role which will have permission to work with DynamoDBand AWS Lambda. Create function in AWS Lambda AWS Lambda Trigger to send mail Add data in DynamoDB Let us discuss each of this step in detail. Example We are going to work out on following example which shows the basic interaction between DynamoDB and AWS Lambda. This example will help you to understand the following operations − Creating a table called customer in Dynamodb table and how to enter data in that table. Triggering AWS Lambda function once the data is entered and sending mail using Amazon SES service. The basic block diagram that ...
