Remote Login Protocols Overview

Remote Login Protocols

• Remote login allows users to interact with host machines as if they are physically present.
• User capabilities vary based on authority level, enabling actions like reading, adding, editing, and deleting files.
• Two main protocols: TELNET and SSH.

TELNET

• TCP/IP standard for establishing connections to remote machines.
• Allows users to sign in over the web via TCP connection.
• Client console connects directly to the remote server.
• Relies on timesharing with user authentication (username and password).

SSH (Secure Shell)

• Advanced remote login protocol based on UNIX.
• Utilizes TCP and provides more powerful access compared to TELNET.
• Offers encryption for secure communication between client and server.
• Protects all client authentication, outputs, commands, and file transfers from network attacks.

Hosting Solutions

• Shared Server: Cost-effective, but resources are shared, potentially slowing down during high traffic.
• Dedicated Server: Most expensive option, ensures exclusive resources for critical operations and high traffic sites.
• Virtual Private Server (VPS): Hybrid solution allowing a portion of server resources, more reliable than shared hosting yet cheaper than dedicated servers.

Web Server Ports and Configurations

• Servers use numbered ports for different services, commonly using port 80 for HTTP.
• Websites hosted on servers require web hosting services that provide storage and accessibility.
• Users access websites through browsers using domain names, facilitated by DNS.

Windows Hosting

• Involves hosting web services on Windows OS, utilizing Microsoft technologies like ASP, .NET, and MSSQL.
• Choose Windows hosting for ASP/ASP.Net scripting or Microsoft database technologies.
• Active Server Pages (ASP): Server-side scripting technology by Microsoft for dynamic web pages.
• Commonly programmed with C# and supports HTML, JavaScript, CSS, and XML.
• ASP is standard on Windows OS, widely available from various hosting providers, especially popular within the Microsoft community.
