How to Install oVirt on CentOS 7

<div dir="ltr" style="text-align: left;" trbidi="on">
oVirt is an open-source distributed virtualization solution, designed to manage your entire enterprise infrastructure. oVirt uses the trusted KVM hypervisor and is built upon several other community projects, including libvirt, Gluster, PatternFly, and Ansible. It was founded by Red Hat as a community project on which Red Hat Enterprise Virtualization is based. It allows centralized management of virtual machines, compute, storage and networking resources, from an easy-to-use web-based front-end with platform independent access. KVM on x86-64 and PPC architecture are the only hypervisors supported, but there is an ongoing effort to support ARM architecture in the future releases. .

 </div>
Log.io is a small application build on Node.js and Socket.io for monitoring real time Linux server logs through web interface. 
 
On RHEL/CentOS 7 
 
Install Epel repositories using the following command. 
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); box-sizing: border-box; clear: none !important; margin-bottom: 10px !important; margin-top: 10px !important; overflow: auto; padding: 10px !important; width: auto !important; word-break: break-all;">yum install http://fedora.mirrors.telekom.ro/pub/epel/7/x86_64/e/epel-release-7-2.noarch.rpm</pre>
On RHEL/CentOS 6 
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); box-sizing: border-box; clear: none !important; margin-bottom: 10px !important; margin-top: 10px !important; overflow: auto; padding: 10px !important; width: auto !important; word-break: break-all;">--------------------- On RHEL/CentOS 6.x - 32 Bit ---------------------
yum install http://fedora.mirrors.telekom.ro/pub/epel/6/i386/epel-release-6-8.noarch.rpm</pre>
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); box-sizing: border-box; clear: none !important; margin-bottom: 10px !important; margin-top: 10px !important; overflow: auto; padding: 10px !important; width: auto !important; word-break: break-all;">--------------------- On RHEL/CentOS 6.x - 64 Bit ---------------------
yum install http://fedora.mirrors.telekom.ro/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm</pre>
After added the Epel repositories you can do a system upgrade by using following command line. 
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); box-sizing: border-box; clear: none !important; margin-bottom: 10px !important; margin-top: 10px !important; overflow: auto; padding: 10px !important; width: auto !important; word-break: break-all;">yum update</pre>
Now Install Node.js and NPM 
 
<a href="https://www.hackthesec.co.in/search/label/Node.Js">Node.js</a> is an open-source, cross-platform JavaScript run-time environment that executes <a href="https://www.hackthesec.co.in/search/label/Java">JavaScript </a>code server-side. Historically, JavaScript was used primarily for client-side scripting, in which scripts written in JavaScript are embedded in a webpage's HTML and run client-side by a JavaScript engine in the user's web browser. Node.js lets developers use JavaScript for server-side scripting—running scripts server-side to produce dynamic web page content before the page is sent to the user's web browser. Consequently, Node.js represents a "<a href="https://www.hackthesec.co.in/search/label/Java">JavaScript </a>everywhere" paradigm, unifying web application development around a single programming language, rather than different languages for server side and client side scripts.now install the nodejs using following command line. 
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); box-sizing: border-box; clear: none !important; margin-bottom: 10px !important; margin-top: 10px !important; overflow: auto; padding: 10px !important; width: auto !important; word-break: break-all;">curl --silent --location https://rpm.nodesource.com/setup_5.x | bash - 
yum install -y nodejs</pre>
Install and Configure Log.io Application 
Log.io application must be installed through NPM by specifying a valid local system user ( example - root) i recommend install this application through root user. now install the application using following command. 
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); box-sizing: border-box; clear: none !important; margin-bottom: 10px !important; margin-top: 10px !important; overflow: auto; padding: 10px !important; width: auto !important; word-break: break-all;">npm install -g log.io --user "root"</pre>
after the completed installation the application will create a folder which is hidden the folder name is "Log.io" in centos 7 the folder path is below 
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); box-sizing: border-box; clear: none !important; margin-bottom: 10px !important; margin-top: 10px !important; overflow: auto; padding: 10px !important; width: auto !important; word-break: break-all;">cd /root/.log.io
ls</pre>
after that you will see three file

Now it's time to configure Log.io to monitor local log files in real time. 
 
- The harvester file is for watches the changes in specified local log files declared in its configuration and send new log to the server. - harvester.conf 
 
First open the harvester.conf file, by default you will see have some setting the monitor Apache log  
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); box-sizing: border-box; clear: none !important; margin-bottom: 10px !important; margin-top: 10px !important; overflow: auto; padding: 10px !important; width: auto !important; word-break: break-all;">nano harvester.conf</pre>

 ]
 },
 server: {
 host: '0.0.0.0',
 port: 28777
 }
 }
</pre>
<div>
Note - if you don't want to send the harvester output to a remote Log.io server then open harvester.conf file and replace 0.0.0.0 address with lookback address(127.0.0.1)</div>
<div>
 </div>
<div>
log_server.conf - This configuration is for tell the server on which ip address it should listen.By default it listens on all ip interfaces you can modify the ip address by using the following command </div>
<div>

 host: '0.0.0.0',
 port: 28777
}</pre>
web_server.conf - This configuration file is for web interface. by default the web portal is accessible on port 28778(all interface). Also using this file you can increase the security by using HTTP authentication,securing the web interface with SSL, disallow logs from specific ip address and restricting the web interface access to the specific ip.

Kali-Linux On Windows</div>
No, really…this isn't clickbait. For the past few weeks, we’ve been working with the Microsoft WSL team to get Kali Linux introduced into the Microsoft App Store as an official WSL distribution and today we’re happy to <a href="https://blogs.msdn.microsoft.com/commandline/2018/03/05/kali-linux-for-wsl/" style="font-family: verdana, geneva, sans-serif; font-size: 15px;">announce </a>the availability of the "Kali Linux" Windows application. For Windows 10 users, this means you can simply enable WSL, <a href="https://www.microsoft.com/en-us/store/p/kali-linux/9pkr34tncv07" style="font-family: verdana, geneva, sans-serif; font-size: 15px;">search for Kali</a> in the Windows store, and install it with a single click. This is especially exciting news for penetration testers and security professionals who have limited toolsets due to enterprise compliance standards. 
<div class="separator" style="clear: both; text-align: center;">

While running Kali on Windows has a few drawbacks to running it natively (such as the lack of raw socket support), it does bring in some very interesting possibilities, such as extending your security toolkit to include a whole bunch of command line tools that are present in Kali. We will update our blog with more news and updates regarding the development of this app as it’s released. 
 
We’d like to take this opportunity to thank the WSL team at Microsoft, and specifically @tara_msft and @benhillis for all the assistance and guidance with which this feat would not be possible. We hope you enjoy WSL’d Kali on Windows 10! 
 
 
And now, a quick guide on getting Kali installed from the Microsoft App Store: 
 
Getting Kali Linux Installed on WSL 
 
Here’s a quick description of the setup and installation process. For an easier copy / paste operation, these are the basic steps taken: 
 
 
1. Update your Windows 10 machine. Open an administrative PowerShell window and install the Windows Subsystem with this one-liner. A reboot will be required once finished. 
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); box-sizing: border-box; clear: none !important; margin-bottom: 10px !important; margin-top: 10px !important; overflow: auto; padding: 10px !important; width: auto !important; word-break: break-all;">Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Windows-Subsystem-Linux</pre>
<div>
 </div>
2. Once rebooted, open the Windows App store and search for the "Kali Linux" application, or alternatively click here to go there directly. Install the app and enjoy Kali! 
Updating Kali Linux on WSL 
 
 
Updating Kali Linux on WSL is no different from any other instance of Kali: 
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); box-sizing: border-box; clear: none !important; margin-bottom: 10px !important; margin-top: 10px !important; overflow: auto; padding: 10px !important; width: auto !important; word-break: break-all;">apt-get update
apt-get dist-upgrade</pre>
Here’s a quick video of the process: 
 
<div class="w-video ratio_16x9" style="background-color: #111111; box-sizing: border-box; color: #666666; font-family: "Open Sans", sans-serif; font-size: 14px;">
<div class="w-video-h" style="box-sizing: border-box; height: 0px; overflow: hidden; padding-bottom: 448.875px; position: relative;">
<iframe allowfullscreen="" mozallowfullscreen="" src="https://player.vimeo.com/video/258822932?portrait=0&color=00adef" style="border-style: none; border-width: initial; box-sizing: border-box; height: 448.875px; left: 0px; max-width: 100%; position: absolute; top: 0px; width: 798px;" webkitallowfullscreen=""></iframe></div>
</div>
<div class="vc_empty_space" style="background-color: white; box-sizing: border-box; color: #666666; font-family: "Open Sans", sans-serif; font-size: 14px; height: 32px;">
 </div>
<div class="vc_empty_space" style="background-color: white; box-sizing: border-box; height: 32px;">
Installing Penetration Testing tools on Kali</div>
<div class="vc_empty_space" style="background-color: white; box-sizing: border-box; height: 32px;">
Installing tools from the Kali Linux repository is usually done via apt commands. For example, to install the Metasploit Framework, you can simply:</div>
<div class="vc_empty_space" style="background-color: white; box-sizing: border-box; height: 32px;">
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); box-sizing: border-box; clear: none !important; margin-bottom: 10px !important; margin-top: 10px !important; overflow: auto; padding: 10px !important; width: auto !important; word-break: break-all;">apt-get update
apt-get install metasploit-framework</pre>
</div>
 
 
Note: Some Kali tools are identified by antivirus software as malware. One way to deal with this situation is to allow antivirus exceptions on the directory in which the Kali chroot resides in. The following video walks you through this process: 
 
<div class="w-video ratio_16x9" style="background-color: #111111; box-sizing: border-box; color: #666666; font-family: "Open Sans", sans-serif; font-size: 14px;">
<div class="w-video-h" style="box-sizing: border-box; height: 0px; overflow: hidden; padding-bottom: 448.875px; position: relative;">
<iframe allowfullscreen="" mozallowfullscreen="" src="https://player.vimeo.com/video/258892544?portrait=0&color=00adef" style="border-style: none; border-width: initial; box-sizing: border-box; height: 448.875px; left: 0px; max-width: 100%; position: absolute; top: 0px; width: 798px;" webkitallowfullscreen=""></iframe></div>
</div>
<div class="vc_empty_space" style="background-color: white; box-sizing: border-box; color: #666666; font-family: "Open Sans", sans-serif; font-size: 14px; height: 32px;">
 </div>
<div class="vc_empty_space" style="background-color: white; box-sizing: border-box; height: 32px;">
Recovering from a failed Kali WSL instance</div>
Sometimes, you can inadvertently kill your Kali WSL instance, due to an overzealous command, an unintentional action, or even due to Kali or WSL bugs. If this happens, here is a quick recovery guide to get back on top of things. Note: this process will wipe your Kali WSL chroot, and re-extract a new copy. Any changes made to the filesystem will be gone, and reset to default. 
 
<div class="w-video ratio_16x9" style="background-color: #111111; box-sizing: border-box; color: #666666; font-family: "Open Sans", sans-serif; font-size: 14px;">
<div class="w-video-h" style="box-sizing: border-box; height: 0px; overflow: hidden; padding-bottom: 448.875px; position: relative;">
<iframe allowfullscreen="" mozallowfullscreen="" src="https://player.vimeo.com/video/258835347?portrait=0&color=00adef" style="border-style: none; border-width: initial; box-sizing: border-box; height: 448.875px; left: 0px; max-width: 100%; position: absolute; top: 0px; width: 798px;" webkitallowfullscreen=""></iframe></div>
</div>
<div class="vc_empty_space" style="background-color: white; box-sizing: border-box; color: #666666; font-family: "Open Sans", sans-serif; font-size: 14px; height: 32px;">
 </div>
Food for thought 
 
The availability of the Kali Linux platform and toolset on Windows 10 brings with it many exciting possibilities which we havent even begun to grasp – here’s one example that got us scratching our heads. While not officially supported by WSL yet, we’ve tested running a desktop manager such as XFCE on WSL’d Kali…and it seems to work quite well: 
 
<div class="w-video ratio_16x9" style="background-color: #111111; box-sizing: border-box; color: #666666; font-family: "Open Sans", sans-serif; font-size: 14px;">
<div class="w-video-h" style="box-sizing: border-box; height: 0px; overflow: hidden; padding-bottom: 448.875px; position: relative;">
