<div>
<span style="color: #222222; font-family: Verdana, Geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;">Django is a free and open source web application framework, written in Python, which follows the model–view–controller architectural pattern. It is maintained by the Django Software Foundation (DSF) and its primary goal is to ease the creation of complex, database-driven websites.</span></span></div>

<span style="font-size: large;"><span style="color: #222222; font-family: Verdana, Geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;">This tutorial applies to <a href="http://www.hackthesec.co.in/search/label/Debian">Debian 7</a>. (but might work on the similar distributions). Before we start with the installation, we need to make sure that our system and our repositories are up to date and then we need to install and create <b>virtualenv</b></span></span><span style="background-color: white; color: #222222; font-family: Verdana, Geneva, sans-serif; font-size: 15px; line-height: 26px;">.</span></span></div>

<div>
<span style="font-size: large;"><div style="color: #222222; font-family: Verdana, Geneva, sans-serif; font-size: 15px; line-height: 26px;">
We have now created the directory which will be the home for <b>virtualenv</b>. Before we proceed with Python packages installation, we need to activate our virtualenv.</div>
<div style="font-family: Verdana, Geneva, sans-serif; line-height: 26px;">
<div style="font-family: 'Times New Roman'; line-height: normal;">
<span style="color: lime; font-family: Courier New, Courier, monospace; font-size: large;"><pre style="background-attachment: scroll; background-clip: initial; background-color: #3c3c3c; background-image: none; background-origin: initial; background-position: 0px 0px; background-repeat: repeat; background-size: initial; border-image-outset: initial; border-image-repeat: initial; border-image-slice: initial; border-image-source: initial; border-image-width: initial; border-radius: 4px; border: 1px solid rgb(229, 229, 229); line-height: 15.6px; margin-bottom: 20px; outline: 0px; overflow: auto; padding: 20px; vertical-align: baseline;"># source /opt/virtualenv/bin/activate</pre>

</div>
<div>
<div style="color: #222222; font-family: Verdana, Geneva, sans-serif;">
<span style="font-size: 15px; line-height: 26px;">We will now notice that see that (<b>virtualenv</b>) has been appended to the beginning of the terminal prompt. This will help us know when our virtualenv is active and which virtualenv is active Now it is time to install <b>Django</b>. To do this, we will use pip, a Python package manager much like easy_install:</span></div>

<div>
<div>
<span style="font-size: large;"><pre style="background-attachment: scroll; background-clip: initial; background-color: #3c3c3c; background-image: none; background-origin: initial; background-position: 0px 0px; background-repeat: repeat; background-size: initial; border-image-outset: initial; border-image-repeat: initial; border-image-slice: initial; border-image-source: initial; border-image-width: initial; border-radius: 4px; border: 1px solid rgb(229, 229, 229); margin-bottom: 20px; outline: 0px; overflow: auto; padding: 20px; vertical-align: baseline;"><span style="line-height: 15.6px;"><span style="color: white;"># pip </span><span style="color: lime;">install django</span></span></pre>
</span></div>
</div>
</div>
<div style="color: #222222; font-family: Verdana, Geneva, sans-serif;">
<span style="font-size: 15px; line-height: 26px;">We now have Django installed. The next step is the database. Most Django users prefer to use <u><a href="http://www.hackthesec.co.in/search/label/PostgreSQL">PostgreSQL</a></u> as their database server. It is much more robust than MySQL and the Django ORM works much better with PostgreSQL than <a href="http://www.hackthesec.co.in/search/label/Mysql">MySQL</a>, MSSQL, or others. We don’t need Virtualenv active for PostgreSQL installation, so we can deactivate it:</span></div>
<div>
<div>
<span style="color: white; font-size: large;"><pre style="background-attachment: scroll; background-clip: initial; background-color: #3c3c3c; background-image: none; background-origin: initial; background-position: 0px 0px; background-repeat: repeat; background-size: initial; border-image-outset: initial; border-image-repeat: initial; border-image-slice: initial; border-image-source: initial; border-image-width: initial; border-radius: 4px; border: 1px solid rgb(229, 229, 229); margin-bottom: 20px; outline: 0px; overflow: auto; padding: 20px; vertical-align: baseline;"><span style="line-height: 15.6px;"># deactivate</span></pre>
<div style="color: black; font-family: 'Times New Roman'; font-size: large;">
<span style="color: #222222; font-family: Verdana, Geneva, sans-serif; font-size: 15px; line-height: 26px;">Then we need to install dependencies for PostgreSQL to work with Django and install PostgreSQL database service:</span></div>
</span></div>
</div>
<div>
<pre style="background-attachment: scroll; background-clip: initial; background-color: #3c3c3c; background-image: none; background-origin: initial; background-position: 0px 0px; background-repeat: repeat; background-size: initial; border-image-outset: initial; border-image-repeat: initial; border-image-slice: initial; border-image-source: initial; border-image-width: initial; border-radius: 4px; border: 1px solid rgb(229, 229, 229); margin-bottom: 20px; outline: 0px; overflow: auto; padding: 20px; vertical-align: baseline;"><span style="line-height: 15.6px;"><span style="color: white;"># sudo apt-get install libpq-dev python-dev
# sudo apt-get install </span><span style="color: lime;">postgresql postgresql-contrib</span></span></pre>
</div>
<div style="color: #222222; font-family: Verdana, Geneva, sans-serif;">
<span style="font-size: 15px; line-height: 26px;"><a href="http://www.hackthesec.co.in/search/label/PostgreSQL">PostgreSQL </a>is now installed. Next thing to install is <a href="http://www.hackthesec.co.in/search/label/NGINX">nginx</a>. We will use nginx as web server, since it fast, light-weight server and compatible with Python. To install it, we simply execute:</span></div>
<div>
<pre style="background-attachment: scroll; background-clip: initial; background-color: #3c3c3c; background-image: none; background-origin: initial; background-position: 0px 0px; background-repeat: repeat; background-size: initial; border-image-outset: initial; border-image-repeat: initial; border-image-slice: initial; border-image-source: initial; border-image-width: initial; border-radius: 4px; border: 1px solid rgb(229, 229, 229); margin-bottom: 20px; outline: 0px; overflow: auto; padding: 20px; vertical-align: baseline;"><span style="line-height: 15.6px;"><span style="color: white;"># sudo </span><span style="color: orange;">apt-get install nginx</span></span></pre>
</div>
<div style="color: #222222; font-family: Verdana, Geneva, sans-serif;">
<span style="font-size: 15px; line-height: 26px;">Gunicorn is a very powerful Python WSGI HTTP Server. It is a Python package we need to first activate our virtualenv to install it. With our virtualenv active, we are going to run this command:</span></div>
<div>
<pre style="background-attachment: scroll; background-clip: initial; background-color: #3c3c3c; background-image: none; background-origin: initial; background-position: 0px 0px; background-repeat: repeat; background-size: initial; border-image-outset: initial; border-image-repeat: initial; border-image-slice: initial; border-image-source: initial; border-image-width: initial; border-radius: 4px; border: 1px solid rgb(229, 229, 229); margin-bottom: 20px; outline: 0px; overflow: auto; padding: 20px; vertical-align: baseline;"><span style="line-height: 15.6px;"><span style="color: white;"># source /opt/myenv/bin/activate
</span><span style="color: lime;"># pip install gunicorn</span></span></pre>
</div>
<div style="color: #222222; font-family: Verdana, Geneva, sans-serif;">
<span style="font-size: 15px; line-height: 26px;">Gunicorn is now installed in our virtualenv. At this point we have everything we need installed. Now, we need to proceed with the services configuration process. We will start our configuration with <b>PostgreSQL</b>. With PostgreSQL we need to create a database, create a user, and grant the user we created access to the database we created. Start off by running the following command:</span></div>
<div>
<pre style="background-attachment: scroll; background-clip: initial; background-color: #3c3c3c; background-image: none; background-origin: initial; background-position: 0px 0px; background-repeat: repeat; background-size: initial; border-image-outset: initial; border-image-repeat: initial; border-image-slice: initial; border-image-source: initial; border-image-width: initial; border-radius: 4px; border: 1px solid rgb(229, 229, 229); margin-bottom: 20px; outline: 0px; overflow: auto; padding: 20px; vertical-align: baseline;"><span style="line-height: 15.6px;"><span style="color: white;"># sudo su – </span><span style="color: lime;">postgres</span></span></pre>
</div>
<div style="color: #222222; font-family: Verdana, Geneva, sans-serif;">
<span style="font-size: 15px; line-height: 26px;">Then, we run this command to create your database and once we have now a database that is named newdb, we will create database user:</span></div>
<div>
<pre style="background-attachment: scroll; background-clip: initial; background-color: #3c3c3c; background-image: none; background-origin: initial; background-position: 0px 0px; background-repeat: repeat; background-size: initial; border-image-outset: initial; border-image-repeat: initial; border-image-slice: initial; border-image-source: initial; border-image-width: initial; border-radius: 4px; border: 1px solid rgb(229, 229, 229); margin-bottom: 20px; outline: 0px; overflow: auto; padding: 20px; vertical-align: baseline;"><span style="line-height: 15.6px;"><span style="color: lime;"># created newdb
</span><span style="color: white;"># createuser –P</span></span></pre>
</div>
<div style="color: #222222; font-family: Verdana, Geneva, sans-serif;">
<span style="font-size: 15px; line-height: 26px;">We will get a series of 6 prompts during the process. The first one will ask you for the name of the new user. The next two prompts are for our password and confirmation of password for the new user. For the last 3 prompts just enter “n” and hit “enter”. This just ensures your new users only has access to what you give it access to and nothing else. Now we can start <b>PostgreSQL</b> console and set access for the new user that we just created:</span></div>
<div>
<pre style="background-attachment: scroll; background-clip: initial; background-color: #3c3c3c; background-image: none; background-origin: initial; background-position: 0px 0px; background-repeat: repeat; background-size: initial; border-image-outset: initial; border-image-repeat: initial; border-image-slice: initial; border-image-source: initial; border-image-width: initial; border-radius: 4px; border: 1px solid rgb(229, 229, 229); margin-bottom: 20px; outline: 0px; overflow: auto; padding: 20px; vertical-align: baseline;"><span style="line-height: 15.6px;"><span style="color: orange;"># psql
</span><span style="color: lime;"># GRANT ALL PRIVILEGES ON DATABASE newdb TO newuser;</span></span></pre>
</div>
<div style="color: #222222; font-family: Verdana, Geneva, sans-serif;">
<span style="font-size: 15px; line-height: 26px;">Now that we have database with user that is able to access it, we need to set those parameters in our Django project. We are going to create new Django project. In order to do that, we need to change to virtualenv directory, activate it and then create new project:</span></div>
<div>
<pre style="background-attachment: scroll; background-clip: initial; background-color: #3c3c3c; background-image: none; background-origin: initial; background-position: 0px 0px; background-repeat: repeat; background-size: initial; border-image-outset: initial; border-image-repeat: initial; border-image-slice: initial; border-image-source: initial; border-image-width: initial; border-radius: 4px; border: 1px solid rgb(229, 229, 229); margin-bottom: 20px; outline: 0px; overflow: auto; padding: 20px; vertical-align: baseline;"><span style="line-height: 15.6px;"><span style="color: white;"># cd /opt/myenv
</span><span style="color: lime;"># source /opt/myenv/bin/activate
</span><span style="color: white;"># django-admin.py startproject newproject</span></span></pre>
</div>
<div style="color: #222222; font-family: Verdana, Geneva, sans-serif;">
<span style="font-size: 15px; line-height: 26px;">We should be able to see a new directory called “newproject” inside our virtualenv directory. This is where our new Django project files live. In order for our project to be able to talk to our database we need to install a additional packages with using pip (while virtualenv still active).</span></div>
<div>
<pre style="background-attachment: scroll; background-clip: initial; background-color: #3c3c3c; background-image: none; background-origin: initial; background-position: 0px 0px; background-repeat: repeat; background-size: initial; border-image-outset: initial; border-image-repeat: initial; border-image-slice: initial; border-image-source: initial; border-image-width: initial; border-radius: 4px; border: 1px solid rgb(229, 229, 229); margin-bottom: 20px; outline: 0px; overflow: auto; padding: 20px; vertical-align: baseline;"><span style="line-height: 15.6px;"><span style="color: white;"># pip install </span><span style="color: lime;">psycopg2</span></span></pre>
</div>
<div style="color: #222222; font-family: Verdana, Geneva, sans-serif;">
<span style="font-size: 15px; line-height: 26px;">Now, we change into our new project’s directory and edit <b>settings.py</b> file using our favorite editor. The database settings in the file should look like:</span></div>
<div style="color: #222222; font-family: Verdana, Geneva, sans-serif;">
<pre style="background-color: whitesmoke; border-radius: 4px; border: 1px solid rgb(204, 204, 204); box-sizing: border-box; color: #333333; font-family: Menlo, Monaco, Consolas, 'Courier New', monospace; font-size: 14px; line-height: 1.42857; margin-bottom: 10.5px; overflow: auto; padding: 10px; word-break: break-all; word-wrap: break-word;"><code style="background-color: transparent; border-radius: 0px; box-sizing: border-box; color: inherit; font-family: Menlo, Monaco, Consolas, 'Courier New', monospace; font-size: inherit; padding: 0px; white-space: pre-wrap;">   DATABASES = {
        'default': {
            'ENGINE': 'django.db.backends.postgresql_psycopg2', # Add 'postgresql_psycopg2', 'mysql', 'sqlite3' or 'oracle'.
            'NAME': 'newdb',                      # Or path to database file if using sqlite3.
            # The following settings are not used with sqlite3:
            'USER': 'newuser',
            'PASSWORD': 'password',
            'HOST': 'localhost',                      # Empty for localhost through domain sockets or           '127.0.0.1' for localhost through TCP.
            'PORT': '',                      # Set to empty string for default.
        }</code></pre>
</div>
<div style="color: #222222; font-family: Verdana, Geneva, sans-serif;">
<span style="font-size: 15px; line-height: 26px;">Now, we should move to our main project directory and make sure virtualenv is activated. Once we make sure that virtualenv is active, we can run the following command so that Django can add its initial configuration and other tables to our database:</span></div>
<div>
<div>
<pre style="background-attachment: scroll; background-clip: initial; background-color: #3c3c3c; background-image: none; background-origin: initial; background-position: 0px 0px; background-repeat: repeat; background-size: initial; border-image-outset: initial; border-image-repeat: initial; border-image-slice: initial; border-image-source: initial; border-image-width: initial; border-radius: 4px; border: 1px solid rgb(229, 229, 229); margin-bottom: 20px; outline: 0px; overflow: auto; padding: 20px; vertical-align: baseline;"><span style="line-height: 15.6px;"><span style="color: orange;"># cd /opt/virtualenv/newproject
</span><span style="color: white;"># source /opt/myenv/bin/activate
</span><span style="color: lime;"># python manage.py syncdb</span></span></pre>
</div>
</div>
<div style="color: #222222; font-family: Verdana, Geneva, sans-serif;">
<span style="font-size: 15px; line-height: 26px;">We should get some output describing what tables were installed, followed by a prompt asking if you want to create a superuser. This is optional and depends on if we want to use Django’s authentication system or the Django admin.</span></div>
<div style="color: #222222; font-family: Verdana, Geneva, sans-serif;">
<span style="font-size: 15px; line-height: 26px;"><br /></span></div>
<div style="color: #222222; font-family: Verdana, Geneva, sans-serif;">
<span style="font-size: 15px; line-height: 26px;">Gunicorn configuration is very specific to our applications needs. First we will go over running Gunicorn with default settings. Here is the command to just run default Gunicorn:</span></div>
<div>
<div>
<pre style="background-attachment: scroll; background-clip: initial; background-color: #3c3c3c; background-image: none; background-origin: initial; background-position: 0px 0px; background-repeat: repeat; background-size: initial; border-image-outset: initial; border-image-repeat: initial; border-image-slice: initial; border-image-source: initial; border-image-width: initial; border-radius: 4px; border: 1px solid rgb(229, 229, 229); margin-bottom: 20px; outline: 0px; overflow: auto; padding: 20px; vertical-align: baseline;"><span style="line-height: 15.6px;"><span style="color: white;"># gunicorn_django --bind </span><span style="color: lime;">**your-fully-qualified-domain-name.com**:8001</span></span></pre>
<div style="color: black; font-family: 'Times New Roman';">
<span style="color: #222222; font-family: Verdana, Geneva, sans-serif; font-size: 15px; line-height: 26px;">If we now point our browser to our-fully-qualified-domain-name.com:8001, we should get the Django welcome screen. Using the command above, we started one worker process only. In production environment we will need more than one. We can control the number of processes from the command line, so if we want to start 5 worker processes, the command will be:</span></div>
</div>
</div>
<div>
<pre style="background-attachment: scroll; background-clip: initial; background-color: #3c3c3c; background-image: none; background-origin: initial; background-position: 0px 0px; background-repeat: repeat; background-size: initial; border-image-outset: initial; border-image-repeat: initial; border-image-slice: initial; border-image-source: initial; border-image-width: initial; border-radius: 4px; border: 1px solid rgb(229, 229, 229); margin-bottom: 20px; outline: 0px; overflow: auto; padding: 20px; vertical-align: baseline;"><span style="color: white;"><span style="line-height: 15.6px;"># gunicorn_django –workers=5 --bind **your-fully-qualified-domain-name.com**:8001</span></span></pre>
</div>
<div style="color: #222222; font-family: Verdana, Geneva, sans-serif;">
<span style="font-size: 15px; line-height: 26px;">If we want to rung Gunicorn and user other than root, then we have:</span></div>
<div>
<div>
<pre style="background-attachment: scroll; background-clip: initial; background-color: #3c3c3c; background-image: none; background-origin: initial; background-position: 0px 0px; background-repeat: repeat; background-size: initial; border-image-outset: initial; border-image-repeat: initial; border-image-slice: initial; border-image-source: initial; border-image-width: initial; border-radius: 4px; border: 1px solid rgb(229, 229, 229); margin-bottom: 20px; outline: 0px; overflow: auto; padding: 20px; vertical-align: baseline;"><span style="line-height: 15.6px;"><span style="color: white;"># gunicorn_django -</span><span style="color: lime;">-workers=5 --user=nobody --bind **your-fully-</span><span style="color: white;">qualified-domain-name.com**:8001</span></span></pre>
</div>
</div>
<div style="color: #222222; font-family: Verdana, Geneva, sans-serif;">
<span style="font-size: 15px; line-height: 26px;">Since we might end up having a lot of different input parameters, it is better if we just create configuration file and use that when starting Gunicorn. We can create our configuration file in virtualenv directory for example (<b>/opt/virtualenv/gunicorn_cfg.py</b>), and put the following configuration for the setting we used before:</span></div>
<div>
<div>
<pre style="background-attachment: scroll; background-clip: initial; background-color: #3c3c3c; background-image: none; background-origin: initial; background-position: 0px 0px; background-repeat: repeat; background-size: initial; border-image-outset: initial; border-image-repeat: initial; border-image-slice: initial; border-image-source: initial; border-image-width: initial; border-radius: 4px; border: 1px solid rgb(229, 229, 229); margin-bottom: 20px; outline: 0px; overflow: auto; padding: 20px; vertical-align: baseline;"><span style="line-height: 15.6px;"><span style="color: white;">command = '/opt/myenv/bin/gunicorn'
pythonpath = '/opt/myenv/myproject'
</span><span style="color: lime;">bind = '127.0.0.1:8001'
</span><span style="color: white;">workers = 5
user = 'nobody'</span></span></pre>
</div>
</div>
<div style="color: #222222; font-family: Verdana, Geneva, sans-serif;">
<span style="font-size: 15px; line-height: 26px;">Now, if we want to run the server, we should execute the following command:</span></div>
<div>
<pre style="background-attachment: scroll; background-clip: initial; background-color: #3c3c3c; background-image: none; background-origin: initial; background-position: 0px 0px; background-repeat: repeat; background-size: initial; border-image-outset: initial; border-image-repeat: initial; border-image-slice: initial; border-image-source: initial; border-image-width: initial; border-radius: 4px; border: 1px solid rgb(229, 229, 229); margin-bottom: 20px; outline: 0px; overflow: auto; padding: 20px; vertical-align: baseline;"><span style="color: white;"><span style="line-height: 15.6px;"># /opt/myenv/bin/gunicorn -c /opt/myenv/gunicorn_config.py myproject.wsgi</span><span style="color: black; font-family: Verdana, Geneva, sans-serif;"><span style="line-height: 15.6px;">
</span></span></span></pre>
<div style="color: #222222; font-family: Verdana, Geneva, sans-serif;">
<span style="font-size: 15px; line-height: 26px;">The “-c” flag, tells gunicorn that we have a config file we want to use, which we pass in just after the “-c” flag. We also pass in a Python dotted notation reference to our WSGI file so that Gunicorn knows where our WSGI file is. For further information about Gunicorn, please read the Gunicorn documentation found at gunicorn.org for more on this topic.</span></div>
</div>
<div style="color: #222222; font-family: Verdana, Geneva, sans-serif;">
<span style="font-size: 15px; line-height: 26px;"><br /></span></div>
<div style="color: #222222; font-family: Verdana, Geneva, sans-serif;">
<span style="font-size: 15px; line-height: 26px;">The last thing we need to do is to configure nginx. Since we are only setting <b><a href="http://www.hackthesec.co.in/search/label/NGINX">NGINX</a> </b>to handle static files we need to first decide where our static files will be stored. We should open our <b>settings.py</b> file for our <b>Django </b>project and edit the <b>STATIC_ROOT</b> line to look like this:</span></div>
<div>
<pre style="background-attachment: scroll; background-clip: initial; background-color: #3c3c3c; background-image: none; background-origin: initial; background-position: 0px 0px; background-repeat: repeat; background-size: initial; border-image-outset: initial; border-image-repeat: initial; border-image-slice: initial; border-image-source: initial; border-image-width: initial; border-radius: 4px; border: 1px solid rgb(229, 229, 229); margin-bottom: 20px; outline: 0px; overflow: auto; padding: 20px; vertical-align: baseline;"><span style="line-height: 15.6px;"><span style="color: orange;">STATIC_ROOT</span><span style="color: white;"> = "/opt/virtualenv/static/"</span></span></pre>
</div>
<div style="color: #222222; font-family: Verdana, Geneva, sans-serif;">
<span style="font-size: 15px; line-height: 26px;">Now that you’ve set up where your static files will be located, we need to configure NGINX to handle the static files and be able to connect to Gunicorn. We should create a new file named <b>/etc/nginx/sites-enabled/newproject</b> and put the following content inside:</span></div>
<div style="color: #222222; font-family: Verdana, Geneva, sans-serif;">
<span style="font-size: 15px; line-height: 26px;"><br /></span></div>
<div style="color: #222222; font-family: Verdana, Geneva, sans-serif;">

location /static/ {
        alias /opt/virtualenv/static/;
    }

        add_header P3P 'CP="ALL DSP COR PSAa PSDa OUR NOR ONL UNI COM NAV"';
    }
}</code></pre>
</div>
<div style="color: #222222; font-family: Verdana, Geneva, sans-serif;">
<span style="font-size: 15px; line-height: 26px;">In order to apply settings, we need to restart Nginx and we are good to go:</span></div>
<div>
<div>
<pre style="background-attachment: scroll; background-clip: initial; background-color: #3c3c3c; background-image: none; background-origin: initial; background-position: 0px 0px; background-repeat: repeat; background-size: initial; border-image-outset: initial; border-image-repeat: initial; border-image-slice: initial; border-image-source: initial; border-image-width: initial; border-radius: 4px; border: 1px solid rgb(229, 229, 229); margin-bottom: 20px; outline: 0px; overflow: auto; padding: 20px; vertical-align: baseline;"><span style="line-height: 15.6px;"><span style="color: lime;"># sudo service nginx restart</span></span></pre>

<span style="color: #222222; font-family: Verdana, Geneva, sans-serif; font-size: 15px; line-height: 26px;">We are done are ready to go now. We can repeated the procedure for creating new application, have another Gunicorn instance running on another port and have additional nginx configuration file</span></div>

<span style="color: #222222; font-family: Verdana, Geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;">SSH keys are by far the most secure way of logging into your cloud server via SSH. Passwords can be eventually cracked using brute-force attacks if they are too easy. If they are complex passwords, they become very hard to remember and writing them down defeats the purpose of a password.</span></span></div>
<div style="text-align: justify;">
<span style="color: #222222; font-family: Verdana, Geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;"><b>SSH </b>keys are nearly impossible to decipher using a brute force attack. If you generate an <a href="http://www.hackthesec.co.in/search/label/SSH">SSH key</a>, you will get a pair of two very long string of characters: a public and private key.</span></span></div>

<div style="text-align: justify;">
<span style="color: #222222; font-family: Verdana, Geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;">Public keys are stored on the server that you’re trying to login to, the only possible tool which could unlock this public key is the private key which will be stored with you. SSH uses this to verify your identity by making sure that your private key can unlock the public key installed on the server.</span></span></div>

<div style="text-align: justify;">
<span style="font-family: Verdana, Geneva, sans-serif;"><span style="line-height: 26px;"><div>
<b><u><span style="color: #0b5394; font-size: large;">Create the <a href="http://www.hackthesec.co.in/search/label/SSH">SSH</a> key pairs</span></u></b></div>
<div style="color: #222222; font-size: 15px;">
The first step is to generate the combination of the public and private key. This can easily be done by opening a terminal window on the machine you will be using to access the remote server (most likely your own workstation).</div>
<div style="color: #222222; font-size: 15px;">
<br /></div>
<div style="color: #222222; font-size: 15px;">
In this example, we will be using RSA keys. The default values should be the correct ones, so you can simply just press enter to accept the default values. However, you may choose to add a passphrase for additional protection.</div>
<div style="color: #222222; font-size: 15px;">
<br /></div>
<div style="color: #222222; font-size: 15px;">
The passphrase is a password which unlocks your private key, which means that in order for someone to gain access, they must have both the private key and your passphrase. You can opt to not using a passphrase if you do not want to type a password each time.</div>

The largest advantage of this module is that it does not require modifications to existing content or workflow, meaning that all internal optimizations and changes to files are made on the server side, presenting modified files directly to the user. Each of 40+ filters corresponds to one of Google’s web performance best practices rules.</span></span><span style="background-color: white; color: #222222; font-family: Verdana, Geneva, sans-serif; font-size: 15px; line-height: 26px; text-align: left;">.</span></div>

<div>
<span style="color: #222222; font-family: Verdana, Geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;">rsync is a widely-used utility to keep copies of a file on two computer systems the same. It is commonly found on Unix-like systems and functions as both a file synchronization and file transfer program. The rsync algorithm, a type of delta encoding, is used to minimize network usage. Zlib may be used for additional compression, and <a href="http://www.hackthesec.co.in/search/label/SSH">SSH </a>or stunnel can be used for data security.</span></span></div>

<span style="color: #222222; font-family: Verdana, Geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;">Rsync is typically used to synchronize files and directories between two different systems. For example, if the command rsync local-file user@remote-host:remote-file is run, rsync will use SSH to connect as user to remote-host.
