Folks,
Here is a sample script which can be used to fetch remote BIND DNS Version by crafting your own DNS structured packets. Currently, this script is not a stable release. As sometimes it hangs while the code doesn’t fetch the response from the server. I am using pdb module to figure out why its happening like so. But I will fix it very soon. BTW, this happens while the target DNS Server doesn’t respond to the bind version query. Apart from that I have some other (TODO) enhancements in the pipeline. Eventually, I will add the enhancements and will make a stable release. I want to make this script a full proof DNS fingerprinting tool (even though there are other third-party tools available in web). Read the rest of this entry »

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.
