What are the characteristics of Linux system?
Features of Linux:
1. Open source
Benefits of open source
① Open source software generally has excellent quality when released.
②Open source spirit
③More secure
2. Openness
The system follows world standards specifications, in particular following the Open Systems Interconnection (OSI) international standards.
3. Multi-user
System resources can be used by the same user, and each user has its own resources (for example: files, devices) They have specific permissions and do not affect each other.
4. Multitasking
It is the computer executing multiple programs at the same time, and the operation of each program is independent of each other.
5. Good user interface
Linux provides two interfaces to users: user interface and system call. Linux also provides users with a graphical user interface. It uses facilities such as the mouse, menus, windows, scroll bars, etc. to present users with an intuitive, easy-to-operate, and highly interactive friendly graphical interface.
6. Device independence
The operating system treats all external devices as files. As long as their drivers are installed, any Users can manipulate and use these devices just like files without knowing their specific existence. Linux is a device-independent operating system and its kernel is highly adaptable.
7. Provides rich network functions
The complete built-in network is a major feature of Linux.
8. Reliable security system
Linux has adopted many security technical measures, including read and write control and protected subsystems , audit trails, core authorization, etc., which provide necessary security guarantees for users in network multi-user environments.
9. Good portability
Transfer the operating system from one platform to another so that it can still be used as required. The ability to operate in its own way. Linux is a portable operating system capable of running in any environment and on any platform, from microcomputers to mainframe computers.
Disadvantages
①Linux requires the use of the command line terminal mode for system management. (The maximum limit of popularity)
②No specific supporting manufacturer
③Insufficient support for games
④Insufficient support for professional software

Linux, the full name is GNU/Linux, is a UNIX-like operating system that is free to use and freely disseminated. Its kernel is written by Linus· First released by Benedict Torvalds on October 5, 1991, it is mainly inspired by the ideas of Minix and Unix. It is a POSIX-based multi-user, multi-tasking operating system that supports multi-threading and multi-CPU. It can run major Unix software tools, applications and network protocols. It supports 32-bit and 64-bit hardware. Linux inherits the network-centric design philosophy of Unix and is a multi-user network operating system with stable performance. There are hundreds of different Linux distributions, such as Debian and Archlinux based on community development, and Red Hat Enterprise Linux, SUSE, Oracle Linux, etc. based on commercial development.

linux设备节点是应用程序和设备驱动程序沟通的一个桥梁;设备节点被创建在“/dev”,是连接内核与用户层的枢纽,相当于硬盘的inode一样的东西,记录了硬件设备的位置和信息。设备节点使用户可以与内核进行硬件的沟通,读写设备以及其他的操作。

区别:1、open是UNIX系统调用函数,而fopen是ANSIC标准中的C语言库函数;2、open的移植性没fopen好;3、fopen只能操纵普通正规文件,而open可以操作普通文件、网络套接字等;4、open无缓冲,fopen有缓冲。

端口映射又称端口转发,是指将外部主机的IP地址的端口映射到Intranet中的一台计算机,当用户访问外网IP的这个端口时,服务器自动将请求映射到对应局域网内部的机器上;可以通过使用动态或固定的公共网络IP路由ADSL宽带路由器来实现。

在linux中,eof是自定义终止符,是“END Of File”的缩写;因为是自定义的终止符,所以eof就不是固定的,可以随意的设置别名,linux中按“ctrl+d”就代表eof,eof一般会配合cat命令用于多行文本输出,指文件末尾。

在linux中,可以利用“rpm -qa pcre”命令判断pcre是否安装;rpm命令专门用于管理各项套件,使用该命令后,若结果中出现pcre的版本信息,则表示pcre已经安装,若没有出现版本信息,则表示没有安装pcre。

在linux中,交叉编译是指在一个平台上生成另一个平台上的可执行代码,即编译源代码的平台和执行源代码编译后程序的平台是两个不同的平台。使用交叉编译的原因:1、目标系统没有能力在其上进行本地编译;2、有能力进行源代码编译的平台与目标平台不同。

linux查询mac地址的方法:1、打开系统,在桌面中点击鼠标右键,选择“打开终端”;2、在终端中,执行“ifconfig”命令,查看输出结果,在输出信息第四行中紧跟“ether”单词后的字符串就是mac地址。

在linux中,rpc是远程过程调用的意思,是Reomote Procedure Call的缩写,特指一种隐藏了过程调用时实际通信细节的IPC方法;linux中通过RPC可以充分利用非共享内存的多处理器环境,提高系统资源的利用率。

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
