Folks,
If you have ever configured ISC BIND DNS in your machines locally and the application is not replying you with the required DNS response then this post is for you. This post will tell how to do a basic troubleshoot if you face such issues. Some couple of days back, I was in need to check DNS version so I crafted my own packet to fetch the installed BIND DNS version (in one of my vmware) but I was coming across with an error that the remote DNS Server is refusing my connection even though my crafted packet was legitimate and was not based on any hack attempts. You can just write a simple program in python (or any programming language) to send the DNS request and fetch the DNS version but make sure that the socket object you are creating is based on UDP as DNS works in UDP.

Folks,
If you come across with any RAR Files and you are not able to exact the target file then unrar command is the right choice for you as tar command doesn’t support extracting RAR Archives. The installation is quite straight forward for both Ubuntu/RPM Based operating systems. If apt-get or yum is supported in your system and your apt-get/yum is able to connect to the Internet and fetch the contents for you (as in old versions of Redhat/Core yum won’t work, even though you can manually fix the repos search paths by editing the conf files) then you can follow these steps to get started.

As we know recently, there had been a hype about SMB v2 protocol vulnerability which was causing BSOD in the vulnerable system. This vulnerability exists in srv2.sys which was not able to handle a higher/lower PID value in the SMB_Negotiate protocol field (2 Bytes). The vulnerability can be successfully exploited by the poc provided by Laurent Gaffié (Found this bug in 3 seconds with his simple hand made fuzzer). And after successful exploitation it will cause a remote BSOD in the affected SMB v2 enabled Operating System thus causing a hard reboot in the machine.

Finally Google made it!
Even though in the web there are some un-official sources for Google Chrome theme customizations, still they were not compatible (sometimes) in everyone’s system. However, finally Google released a stable version where they are supporting customization of themes and providing a wide range of good themes in their tools page. Almost all themes are looking quite sleek but from all of them Greyscale theme looks quite alluring.
