What is a Linux server
A Linux server is a computer running the Linux operating system that provides services and resources to multiple clients over a network. Linux servers are commonly used for a wide range of purposes, including:
i. Web hosting: Linux servers can host websites and web applications, serving web pages and dynamic content to users.
ii. File and print services: Linux servers can act as file servers, providing centralized storage and access to files, and as print servers, managing printers and print jobs.
iii. Database management: Linux servers can host databases, providing access and management of data for applications.
iv. Email services: Linux servers can run email servers, providing email services and managing email accounts.
v. Application hosting: Linux servers can host and run various applications, providing access and resources for users.
Linux servers are popular for their stability, security, and flexibility, and are widely used in both large enterprises and small businesses.
Connection options
There are several options to connect to a Linux server, including:
SSH (Secure Shell): A secure and encrypted network protocol that can be used to access remote servers.
Telnet: A protocol for establishing a text-based connection to a remote server, but is considered insecure as it does not encrypt data.
RDP (Remote Desktop Protocol): A protocol used to remotely access and control a desktop environment, commonly used on Windows systems.
VNC (Virtual Network Computing): A graphical desktop sharing system that allows remote access to a user’s desktop environment.
FTP (File Transfer Protocol): A protocol used to transfer files between computers, can also be used to transfer files to and from a remote server.
SCP (Secure Copy): A secure file transfer protocol that uses SSH encryption to transfer files between servers.
The best option to connect to a Linux server will depend on the specific needs and requirements of your environment and use case.
In this article, we are going to dive deep into SSH as a connection option to Linux servers and illustrate how connection can be achieved.
SSH in details
In detailed, SSH (Secure Shell) is a network protocol used to securely access remote servers. It provides a secure and encrypted connection between two computers over the internet and can be used to execute shell commands, transfer files, or establish a secure VPN (Virtual Private Network) connection. SSH is commonly used by developers, system administrators, and other IT professionals to manage remote servers, applications, and data.
To connect to a Linux server using SSH, briefly, follow these steps:
Open a terminal or command line on your local machine
Type the following command and replace “username” and “server_IP_address” with the appropriate values:
ssh username@server_IP_address
3. Enter your password when prompted.
4. You should now be connected to the remote server.
Note: If the remote server has a different SSH port number, use the following command:
ssh -p port_number username@server_IP_address
