<span style="box-sizing: border-box;"><span style="font-family: "georgia" , "times new roman" , serif;">PromDash is a tool that allows to create custom dashboards which are not only highly configurable but also better-looking. It is generally used for debugging purposes or to run one-off queries.</span></span></div>
<div style="background-color: #fdfdfd; box-sizing: border-box; font-size: 18px; line-height: 28px; margin-bottom: 10.5px;">
<span style="box-sizing: border-box;"><span style="font-family: "georgia" , "times new roman" , serif;">So this is the preferred way to visualize the data in Prometheus’ time-series database by using PromDash.</span></span></div>
<div style="background-color: #fdfdfd; box-sizing: border-box; font-size: 18px; line-height: 28px; margin-bottom: 10.5px;">
<span style="box-sizing: border-box;"><span style="font-family: "georgia" , "times new roman" , serif;">To download and run PromoDash, you need to install some of its required packages like Git, Ruby and a few build tools by executing the following ‘Yum’ command.</span></span></div>
<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;"><span style="box-sizing: border-box;">$ sudo yum install git ruby ruby-devel gcc gcc-c++ sqlite-devel zlib-devel patch automake</span></pre>

<span style="box-sizing: border-box;"><span style="font-family: "georgia" , "times new roman" , serif;">Type ‘y’ and hit Enter key to proceed with the installation including its dependent packages. Once the installation is completed run the command below to clone git repository of the PromoDash package.</span></span></div>
<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;"><span style="box-sizing: border-box;">$ git clone https://github.com/prometheus/promdash.git</span></pre>

<span style="background-color: #fdfdfd; color: #333333; font-size: 18px; line-height: 28px;"><span style="font-family: Georgia, Times New Roman, serif;">A virtual private network (VPN) is network that extends a private network (i.e. LAN) across a public network, such as the Internet. It enables a communications between computers and devices across shared or public networks as if it were directly connected to the private network, while benefiting from the functionality, security and management policies of the private network.</span></span></div>

<span style="color: #0b5394;"><u>Server side setup and configuration</u></span></h3>
<div style="background-color: #fdfdfd; box-sizing: border-box; font-size: 18px; line-height: 28px; margin-bottom: 10.5px;">
<span style="font-family: Georgia, Times New Roman, serif;">The most popular VPN solutions are OpenVPN and PPTP. We will use PPTP. Before we proceed and setup our own VPN network, we should have one computer that will be the VPN server. That computer will be responsible for assigning IP addresses to the clients, establishing initial connection between the clients or between client and the server, handling the security protocols and users/clients authentication. In order to install PPTP we will execute the following command:</span></div>
<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;"># apt-get install pptpd
</code></pre>
<div style="background-color: #fdfdfd; box-sizing: border-box; font-size: 18px; line-height: 28px; margin-bottom: 10.5px;">
<span style="font-family: Georgia, Times New Roman, serif;">Alternatively, if we are using <a href="http://www.hackthesec.co.in/search/label/Centos" target="_blank">CentOS</a> we should execute:</span></div>
<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;"># rpm -i http://poptop.sourceforge.net/yum/stable/rhel6/pptp-release-current.noarch.rpm
# yum -y install pptpd
</code></pre>
<div style="background-color: #fdfdfd; box-sizing: border-box; font-size: 18px; line-height: 28px; margin-bottom: 10.5px;">
<span style="font-family: Georgia, Times New Roman, serif;">Next step is to edit the default configuration file <code style="background-color: #f9f2f4; border-radius: 4px; box-sizing: border-box; font-size: 16.2px; padding: 2px 4px;"><span style="color: red;">/etc/pptpd.conf</span></code>, using our favourite editor and add the following lines:</span></div>
<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;">localip 172.16.0.1
remoteip 172.16.0.100-200
</code></pre>
<div style="background-color: #fdfdfd; box-sizing: border-box; font-size: 18px; line-height: 28px; margin-bottom: 10.5px;">
<span style="font-family: Georgia, Times New Roman, serif;">In this case, 172.16.0.1 is the IP that will be used inside the VPN by the VPN server, and An IP from the range 172.16.0.100-200 will be assigned to each client that will be authenticated.</span></div>
<div style="background-color: #fdfdfd; box-sizing: border-box; font-size: 18px; line-height: 28px; margin-bottom: 10.5px;">
<span style="font-family: Georgia, Times New Roman, serif;">Now we need to add new users. The file that contains the users and their password is <code style="background-color: #f9f2f4; border-radius: 4px; box-sizing: border-box; font-size: 16.2px; padding: 2px 4px;"><span style="color: red;">/etc/ppp/chap-secrets</span></code>. The client should be entered with the following information in the following order:</span></div>
<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;"># client        server  secret                  IP addresses
</code></pre>
<div style="background-color: #fdfdfd; box-sizing: border-box; font-size: 18px; line-height: 28px; margin-bottom: 10.5px;">
<span style="font-family: Georgia, Times New Roman, serif;">In order to create new client called <span style="color: red;"><code style="background-color: #f9f2f4; border-radius: 4px; box-sizing: border-box; font-size: 16.2px; padding: 2px 4px;">client1</code> </span>that will be able to use the <code style="background-color: #f9f2f4; border-radius: 4px; box-sizing: border-box; font-size: 16.2px; padding: 2px 4px;">pptpd</code> server from any location using the password <span style="color: red;"><code style="background-color: #f9f2f4; border-radius: 4px; box-sizing: border-box; font-size: 16.2px; padding: 2px 4px;">password1</code> </span>we should add the following line, in the following case, the asterisk means that anyone IP address can use that login information:</span></div>
<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;">client1  pptpd    password1   *
</code></pre>
<div style="background-color: #fdfdfd; box-sizing: border-box; font-size: 18px; line-height: 28px; margin-bottom: 10.5px;">
<span style="font-family: Georgia, Times New Roman, serif;">The last thing that we need to do before starting our VPN server is to add DNS server. We can add the DNS servers provided by or internet provider or we can use Google DNS servers and insert them in the file.</span></div>
<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;">ms-dns 8.8.8.8

<span style="font-family: Georgia, Times New Roman, serif;">Now we can start the pptpd daemon using the command:</span></div>
<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;">service pptpd start

<span style="font-family: Georgia, Times New Roman, serif;">In order to verify that it is running and listening for incoming connections, we should execute:</span></div>

<span style="font-family: Georgia, Times New Roman, serif;">In order for VPN server to work properly and be able to forward the requests we should make sure that the following line exists in <code style="background-color: #f9f2f4; border-radius: 4px; box-sizing: border-box; font-size: 16.2px; padding: 2px 4px;"><span style="color: red;">/etc/systl.conf</span></code>.</span></div>

<span style="font-family: Georgia, Times New Roman, serif;">After starting the client, check the log files for possible errors or successful connection info using the following command:</span></div>
<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;"># cat /var/log/syslog | grep pptp

<span style="font-family: Georgia, Times New Roman, serif;">We should explicitly set proper routing for the VPN traffic on our clients:</span></div>
<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;">ip route add 172.16.0.0/16 dev ppp0

<span style="font-family: Georgia, Times New Roman, serif;">Once this is done, we can repeat the procedure and add more client and they will all be able to communicate to each other inside secured virtual private network. The computer can communicate using any protocol or service, such as HTTP, SMTP, telnet, MySQL, FTP etc. PPTP server doesn’t demand high usage of CPU resources, but still, all traffic is 128-bit encrypted. This provides decent level of security and protection for our sensitive data and information.</span></div>

<span style="font-family: "georgia" , "times new roman" , serif;">If we restart nginx and start ghost again, we should get Ghost welcome page in our browser. If that is the case, we are done with the installation. The last thing we need to do is to make us able to start/stop the Ghost service like any other server on Ubuntu, using service start and service stop commands. In order to do that we need to create new file in <code style="background-color: #f9f2f4; border-radius: 4px; box-sizing: border-box; font-size: 16.2px; padding: 2px 4px;"><span style="color: red;">/etc/init</span></code> directory.</span></div>
