Lime is a Loadable Kernel Module (LKM) which allows for volatile memory acquisition from Linux and Linux-based devices, such as Android. This makes LiME unique as it is the first tool that allows for full memory captures on Android devices. It also minimises its interaction between user and kernel space processes during acquisition, which allows […]
Since some months I have not been posting anything on my blog. I should admit that I was really busy. Recently, a friend asked me about the Out of Memory messages in Linux. How is it generated? What are the consequences? How can it be avoided in Linux machines? There is no specific answer to […]
In the article Linux kernel crash simulation using kdump, I gave a brief idea as to how to generate a vmcore file during a crash or hangs. On this article, I will emphasize the analysis of a vmcore which has been generated and the tool ‘crash’ which can be used for advanced analysis. In a […]
The Linux Kernel 4.3 has been released today, Monday the 2nd of November 2015. I have compiled it from source on a Virtual Box CentOS 7 minimum install the virtual machine for some further testing.

In fact, these are totally two different issues; a “hang” occurs due to a time-consuming operation whilst a “crash” occurs instantaneously leading to a […]
