Data Display Debugger as the name suggests is a display software for debugs that acts as a graphical interface for other debugging platforms such as DBX, JDB, XDB, GDB, ladebug, bashdb, and the perl debugger among others. Aside from common GUI functions such as displaying source texts, this software displays all the information in in-depth charts and graphs with engaging and interactive dashboards which makes it easy for even novice users to understand the information displayed.
Strace is a software developed for Linux Operating System that identifies and debugs malware. It can also monitor and change interactions between processes and Linux Kernel such as signal deliveries, system calls, and state process changes. If a program crashes repeatedly or performs poorly, this software can correct it by printing all the system calls made by the program. Another feature is this software’s ability to enumerate syscall names, paths, and file descriptions that it wants to trace. Codes of specified syscalls can be edited and signals can be injected into them.
Some other features include easy to use interface, information extraction about file descriptions, tracking execution time and count, filtration, relative and absolute timestamps printing, and printing of stack traces and system demangling.
Novell Linux Kernel Debugger is debugging software for the Linux Operating System that identifies and removes errors, malware, and bugs from the Kernel of the Operating System. Aside from local debugging, users can also debug remotely. Some of this software’s most alluring features are open-sourcing, high functionality, robust debugging, and ease of usage.
EDB Debugger is a cross-platform debugging software for AArch32/x86/x86-64 that can perform strong and dialectic analysis of the binaries. It comes with a graphical interface that consists of four primary regions: Stack view, data view, register view, and Disassembly view. All of these can be tweaked according to the user’s needs.
Apart from common debugging operations such as step-into/step-over/run/break etc., it can also analyze instructions, check addresses, and view or dispose of memory regions. Symbol maps can be created or imported. Some of this platform’s applicable features include Cloning, compiling options, configuration options, breakpoints, plugins, color highlight, drag and drop function, user help, and coherent dashboard.
kdbg Debugger is a user interface for gdb and GNU debugger platforms. It is fairly simple to use. To debug a file, you simply have to select it from the main menu and execute it. This software can thoroughly inspect variables and codes as well as set/clear/enable or disable breakpoints. Likewise, it can also be used for text searching and viewing source code. This software can even operate with already running programs and debug core dumps.
