Overview to an VIM editor

  Vim is a versatile text editor that can be used for a wide range of tasks. Its power and flexibility make it a popular choice among developers, system administrators, writers, and anyone who works extensively with text files. Here are some common uses of Vim: Code Editing: Vim is often used by programmers for editing source code. Its syntax highlighting, code folding, and extensive keyboard shortcuts make it efficient for writing and editing code in various programming languages. Text File Editing: You can use Vim for editing plain text files, configuration files, log files, and more. Its search and replace functionality is particularly useful for making bulk changes in text documents. System Administration: System administrators often use Vim to edit configuration files, scripts, and other system-related text files on Linux and Unix-based systems. Writing and Note-taking: Some writers and note-takers prefer Vim for distraction-free writing. It offers features like spell-chec...

Overview to SSH

 

SSH, or Secure Shell, is a network protocol that allows you to securely access a remote computer over an unsecured network. It is often used by system administrators to manage servers, but it can also be used by anyone who needs to access a remote computer in a secure way.

SSH works by encrypting all data that is sent between the client and the server. This means that even if someone is able to intercept the data, they will not be able to read it. SSH also provides authentication, so that only authorized users can access the remote computer.

There are many different ways to use SSH. Here are a few common uses:

  • To access a remote server and manage it.
    This is the most common use of SSH. System administrators use SSH to
    install software, configure settings, and troubleshoot problems on
    remote servers.
  • To transfer files between computers. SSH
    can be used to securely transfer files between two computers, even if
    they are on different networks.
  • To connect to a remote database. SSH can be used to connect to a remote database and run queries.
  • To connect to a remote application. SSH can be used to connect to a remote application and run it.

If you need to access a remote computer securely, SSH is the best way to do it. It is a reliable and secure protocol that is used by millions of people around the world.

Here are some additional benefits of using SSH:

  • It is easy to use. Once you have installed SSH, you can start using it right away.
  • It is available for all major operating systems. You can use SSH on Windows, macOS, Linux, and other operating systems.
  • It is free to use. There is no cost to download and use SSH.

So is that ssh is use by terminal only, is it have GUI option ?

By default, SSH is used in a terminal only. However, there are GUI options available for SSH.

One way to use SSH with a GUI is to use a SSH client application. There are many SSH client applications available for all major operating systems. Some popular SSH client applications include PuTTY, SecureCRT, and MobaXterm.

Another way to use SSH with a GUI is to use a remote desktop protocol (RDP). RDP is a protocol that allows you to connect to a remote computer and view its desktop as if you were sitting in front of it. You can then use the remote computer's GUI applications.

To use SSH with RDP, you need to install an RDP client application on your computer. You also need to configure the remote computer to allow RDP connections. Once you have done this, you can connect to the remote computer using the RDP client application.

Here are some of the benefits of using SSH with a GUI:

It is more user-friendly. Using a GUI is often easier than using a terminal.

It is more secure. A GUI can help to protect your data from unauthorized access.

It is more versatile. A GUI can be used to connect to a wider range of remote computers and applications.

Connecting through SSH

Create SSH keys

SSH keys are a pair of files that are used to authenticate you when you connect to a remote computer using SSH. The public key is placed on the remote computer, and the private key is kept on your local computer.

To create SSH keys, you can use the ssh-keygen command. This command will generate a public key and a private key in the current directory.

ssh-keygen

You will be prompted to enter a passphrase for the private key. This passphrase is optional, but it is recommended that you use one.

Connect to a remote computer using SSH

Once you have created SSH keys, you can connect to a remote computer using SSH. To do this, you need to know the IP address or host-name of the remote computer, and the username that you want to use to connect.

The following command will connect you to the remote computer using your SSH keys:

ssh username@remote_computer_ip_address

For example, if you want to connect to a remote computer with the IP address 192.168.1.100 and the username user, you would use the following command:

ssh user@192.168.1.100

If you are prompted for a password, enter the passphrase that you created when you generated your SSH keys.

Connect to a remote computer using a SSH client

If you prefer to use a SSH client application, you can do so. There are many SSH client applications available for all major operating systems. Some popular SSH client applications include PuTTY, SecureCRT, and MobaXterm.

To connect to a remote computer using a SSH client application, you need to know the IP address or hostname of the remote computer, and the username that you want to use to connect. You also need to know the port number that SSH is listening on. The default port number for SSH is 22.

Once you have entered the required information, the SSH client application will connect to the remote computer and you will be able to access it.

Here are some of the various ways to connect to a remote computer using SSH:

  • Using the ssh command in a terminal
  • Using a SSH client application
  • Using a remote desktop protocol (RDP)

The best way to connect to a remote computer using SSH will depend on your individual needs and preferences.

File System Hierarchy and Permissions - Linux

  File System Hierarchy: The Unix-like file system hierarchy is a structured organization of directories and files. It starts from the root directory ("/") and branches out into various subdirectories. Here are some of the most important directories and their purposes: / (Root Directory): The top-level directory in the file system hierarchy. Everything on the system is under this directory. /bin (Binary): Contains essential system binaries (executable files) required for system booting and repair. /boot: Contains boot-related files, including the kernel and bootloader configuration. /dev (Devices): Contains device files representing hardware devices, such as hard drives, keyboards, and serial ports. /etc (Etcetera): Houses system-wide configuration files and scripts. /home: User home directories are stored here. Each user has their own subdirectory here. /lib (Library): Contains shared libraries needed by system programs and applications. /mnt (Mount): Used for tempor...

What is kernal and its types and uses?

A kernel is the central component of an operating system that manages all the resources and communicates with both software applications and hardware devices on a computer. In simple terms, it acts as an intermediary between the user’s requests and the computer's hardware. A kernel provides a variety of services to other parts of the operating system and to applications, including memory and process management, interrupt handling, and system calls. It also acts as a bridge between the hardware and software components, translating requests from the software into actions performed by the hardware.  There are different types of kernels, including monolithic kernels, microkernels, and hybrid kernels.  Monolithic kernels are designed to be large and comprehensive, providing all the basic system functions in a single, unified binary file.  Microkernels, on the other hand, are designed to be small and modular, with each component of the system being implemented as a separate pr...
