October 20, 2016Security issues on the internet can arise from many different sides. Though we often believe that viruses and other forms of malware are greatest threats that World Wide Web has to offer, situation is actually a lot more complicated than that. Our security is also challenged by the level of surveillance on the web, because practically our every step can be easily monitored, and in that monitoring helps everything – from your browser to your operating system. This is the reason why more and more people opt out for using alternative versions of operating systems, and so far Linux has proven to be at the very top. Fedora and Ubuntu are thus far the best offspring of Linux family, which is why security-conscious internet users often choose one of them as their OS. However, with alternative operating systems come compatibility issues that need to be considered, because you’ll face some difficulty when wanting to install different apps and plugins. Further more, if you strive to be as protected as possible on the web, then getting a VPN to match your alternative OS might be a good idea, because that way you’ll cover every aspect of your security. Seeing that compatibility problems stretch over VPN apps as well, here are some of them that will fit like a glove with your OS. Cyber Ghost We’ll start with a VPN that can grant you solid protection and which you can get without paying a dime. Cyber Ghost in its free edition can give you a good Open VPN protocol along which also comes unlimited bandwidth, which is pretty good for a free VPN. You will also get a kill switch, which will protect you from losing your privacy if you lose your VPN connection. One of the best things about Cyber Ghost...

July 16, 2014Step-By-Step On How to Install Asterisk GUI This should work in any RPM linux based system (Red Hat, CentOS, Federa, exc) Download the latest version source files using svn. (yum install subversion) cd /usr/src svn checkout http://svn.digium.com/svn/asterisk-gui/branches/2.0 asterisk-gui cd asterisk-gui ./configure make make install I recommend backing up your configuration files before you continue. To achieve this just copy /etc/asterisk under different name: cp -r /etc/asterisk /etc/asterisk.backup There are two files which you should modify 1. /etc/asterisk/manager.conf` enabled = yes webenabled = yes We will have to add a new user to manager.conf: [administrator] secret = mysecret read = system,call,log,verbose,command,agent,user,config write = system,call,log,verbose,command,agent,user,config `/etc/asterisk/http.conf` enabled=yes enablestatic=yes bindaddr=0.0.0.0 bindport = 8088 prefix = gui enablestatic = yes Note: bindaddr 0.0.0.0 means you can access it from anywhere, if you want access only on the local machine, put 127.0.0.1 instead. Check your Asterisk-GUI configuration by running from /usr/src/asterisk-gui make checkconfig This script will check if your GUI is correctly configured. Running asterisk-gui. In order to load the asterisk-gui, asterisk must restart/reload. You can reload your Asterisk server from your CLI console by executing the command `reload`. You can use asterisk-gui from these address: http://10.100.32.50:8088/static/config/index.html http://10.100.32.50:8088/httpstatus (to check the status) http://www.asterisk.org/

June 18, 20141. CentOS Updates Update your CentOS 6 Server for any possible unimplemented updates. yum update -y 2. Disabling SELinux You can use any text editor (VIM etc) to commit this change. Go to /etc/selinux/config and change SELINUX=enforcing to SELINUX=disabled This can also be done by using command line: sed -i s/SELINUX=enforcing/SELINUX=disabled/g /etc/selinux/config 3. Reboot Once the aforementioned change is committed and the file is updated, reboot the system using: reboot 4. Installation of Basic Dependencies Asterisk 11.0.0 requires some prerequisite dependencies. Here is the command line to install them: yum install -y make wget openssl-devel ncurses-devel newt-devel libxml2-devel kernel-devel gcc gcc-c++ sqlite-devel 5. Downloading Your Asterisk Source Code Move to directory /usr/src by given command: cd /usr/src/ and then download the Source Code tar balls using these commands (one by one or at a time): wget http://downloads.asterisk.org/pub/telephony/dahdi-linux-complete/dahdi-linux-complete-current.tar.gz wget http://downloads.asterisk.org/pub/telephony/libpri/libpri-1.4-current.tar.gz wget http://downloads.asterisk.org/pub/telephony/asterisk/asterisk-11-current.tar.gz 6. Extraction of Downloaded Files Extract the downloaded tar balls to their corresponding directories using: tar zxvf dahdi-linux-complete* tar zxvf libpri* tar zxvf asterisk* 7. DAHDI Installation DAHDI (Digium Asterisk Hardware Device Interface) can be installed using the command line: cd /usr/src/dahdi-linux-complete* make && make install && make config 8. LibPRI Installation In order to enable your BRI, PRI and QSIG based hardware, you will be needing PRI Library or LibPRI. You can install these libraries using: cd /usr/src/libpri* make && make install 9. Changing Asterisk Directory Now you have to move back to the Asterisk Installation Directory: cd /usr/src/asterisk* 10. Running Configure Script for Asterisk At this point, you need to know your CentOS 6 Architecture (32 or 64 Bit). In many cases you are aware of it. In case you are not, try this command: uname -a For 32 Bit, you will be getting response like: 2.6.18-238.12.1.el5 #1...

May 22, 2014The best platform that you can use for network performance monitoring is Linux. Why? The biggest reason to use Linux is because of its open source nature. Over the years, programmers have developed a lot of useful commands that can be used on any kind of system. Being a network or system administrator can be a really hard thing to do. Monitoring and debugging systems all day long can be really exhausting. If you plan on doing this job, eventually you will realize how hard it is to monitor and keep systems up and running. Because of this, I have made a list of some often used command line monitoring tools that prove to be useful in everyday work. These tools help you monitor traffic flow through network interfaces and can show you the speed of data transfer on your network. You can also use some of these commands to see clearly how much bandwidth some particular processes use. Netstat Netstat is short for network statistics and you can guess what it is about. It is used to monitor incoming and outgoing network packets statistics. It is also used to see your interface statistics. For an administrator that monitors and fixes troubleshooting problems of a network, this tool is very useful. Lsof If you want to see all current files and processes that are currently active, Lsof is the command that you use. The files that are shown include network sockets, disk files, devices and processes. The main reason for using this command is if some file reports that it is being used and you don’t know by what. With this command, you can easily see which files are being used and by whom. Nload In certain situations, monitoring traffic will not be enough. Monitoring incoming and outgoing traffic separately...

October 31, 2013RootCheck is an Open Source software that scans all the system looking for possible problems (RootKit Detection), system auditing and policy monitoring parts of OSSEC. The result of the scan can be sent to an e-mail and you can choose between the html or text format. RootCheck is an extremely useful open source software for servers since it scans the server and finds any problems on it. It is a very simple software. Just download, unpack, compile and execute it. It will scan the whole system and print if it founds or not anything. Installation of RootCheck 1. # wget http://www.ossec.net/rootcheck/files/rootcheck-2.0.tar.gz 2. # tar -zxvf rootcheck-2.0.tar.gz 3. # cd rootcheck-2.0 4. # make 5. # ./ossec-rootcheck If you would like to force a scan again type this command ./rootcheck.pl

August 30, 2013Conky is highly configurable and is able to monitor many system variables including the status of the CPU, memory, swap space, disk storage, temperatures, processes, network interfaces, battery power, system messages, e-mail inboxes, Linux updates, many popular music players, and much more. Conky has gained a strong following among many Linux and BSD enthusiasts. Unlike system monitors that use high-level widget toolkits to render their information, Conky is drawn directly in an X window. This allows it to consume relatively fewer system resources when configured similarly. Not only does Conky have many built-in objects, it can also display just about any piece of information by using scripts and other external programs. Conky features built-in support for several unrelated sources of information, but its biggest strength lies in its extensibility through scripting. Conky can be extened threw python scripting many Conky versions are used in WordPress blogs for written visualization tools. Conky is supported natively on Debian, Ubuntu, FreeBSD, Gentoo, Arch, Foresight, and can be compiled from source. The name Conky comes from a character in the Canadian TV show titled “Trailer Park Boys”. Conky has been licensed under the GPL 3.0. The download is hosted on SourceForge and the project can be joined on GitHub.
