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 exp

Unix / Linux - Shell Input/Output Redirections

W e will discuss in detail about the Shell input/output redirections. Most Unix system commands take input from your terminal and send the resulting output back to your terminal. A command normally reads its input from the standard input, which happens to be your terminal by default. Similarly, a command normally writes its output to standard output, which is again your terminal by default. Output Redirection The output from a command normally intended for standard output can be easily diverted to a file instead. This capability is known as output redirection. If the notation > file is appended to any command that normally writes its output to standard output, the output of that command will be written to file instead of your terminal. Check the following  who  command which redirects the complete output of the command in the users file. $ who > users Notice that no output appears at the terminal. This is because the output has been redirected from the default standard output dev

Unix / Linux - Shell Functions

W e will discuss in detail about the shell functions. Functions enable you to break down the overall functionality of a script into smaller, logical subsections, which can then be called upon to perform their individual tasks when needed. Using functions to perform repetitive tasks is an excellent way to create  code reuse . This is an important part of modern object-oriented programming principles. Shell functions are similar to subroutines, procedures, and functions in other programming languages. Creating Functions To declare a function, simply use the following syntax − function_name () { list of commands } The name of your function is  function_name , and that's what you will use to call it from elsewhere in your scripts. The function name must be followed by parentheses, followed by a list of commands enclosed within braces. Example Following example shows the use of function − #!/bin/sh # Define your function here Hello () { echo "Hello World" } # Invoke yo
