Duf Utility In Linux To View Disk Usage

Duf Utility In Linux To View Disk Usage

Linux
The most commonly used application to view disk usage in Linux is du. Du stands for disk usage, is being widely used to find out which files and directories have occupied the most disk space. There are many other command lines and graphical tools that exist to accomplish this task. Today, we will cover a disk usage checker named duf. Duf (disk usage/free) is a command-line utility to find disk usage in Linux and Unix systems. It displays the disk usage details in a nice tabular-column and user-friendly layout. You can even get the disk usage output in JSON format as well. If the output exceeds the visible part of the screen, it automatically adjusts the terminal's width. You can sort the results by total size, filesystem type, used and free space, mount point, and inodes. ...

ace-VoIP Information Gathering Tool

Kali
ACE (Automated Corporate Enumerator) is a simple yet powerful VoIP Corporate Directory enumeration tool that mimics the behavior of an IP Phone in order to download the name and extension entries that a given phone can display on its screen interface. In the same way that the “corporate directory” feature of VoIP hard phones enables users to easily dial by name via their VoIP handsets. ACE was developed as a research idea born from “VoIP Hopper” to automate VoIP attacks that can be targeted against names in an enterprise Directory. The concept is that in the future, attacks will be carried out against users based on their name, rather than targeting VoIP traffic against random RTP audio streams or IP addresses. ACE works by using DHCP, TFTP, and HTTP in order to download the VoIP corpo...
Inodes in Linux

Inodes in Linux

Linux
Everything in Linux considered as file. This is just to maintain the consistency. Everything means keyboard, mouse, printers, monitor, hard disk, processes, even the folder or directories are treated as file in Linux. The regular files contain data such as text files, mp3, multimedia files, configuration files. Files contain some administrative information about them, such as their size, ownership, permissions. This metadata about a file in managed with a data structure known as an inode i.e. index node. There are three times in the inode: contents of the file last modified (write)file was last used (read or execute)inode itself was last changed Changing the contents of a file does not affect its usage time. Changing the permission affects only the inode change time. For e...

Linux Files Basics

Linux Files Basics

Linux
Everything in Linux is a file. A file is a sequence of bytes. A byte is 8 bits long. The Linux system does not impose any structure or meaning on a file. It fully depends on the program that interprets the file. To learn more about files, let's create one. I created a file name sample.txt using vi editors. The file contains two lines. To see the file on the terminal, use the cat command followed by the file name. Sample.txt is a file with 73 bytes. 73 bytes means there are 73 characters in the file including spaces and periods. To check the size of the Linux files with the permissions and owner, use the ls -l command followed by the file name. The command od (octal dump) provides you a visible representation of all the bytes of a file. If you append an option i.e. ...
