While smbclient is primarily used for interacting with SMB shares (like listing shares or accessing files),, it can implicitly indicate if port 445 is open and accessible. If smbclient can successfully connect to an SMB share on a target system, it means port 445 is open on that system and allowing connections. How it works: When you use smbclient Read More …

LCP – Link Control Protocol
The Link Control Protocol (LCP) is a critical component of the Point-to-Point Protocol (PPP), which is widely used for establishing direct connections between two network nodes. LCP plays a vital role in the setup, configuration, and management of PPP connections, making it essential for ensuring reliable and efficient data transmission over point-to-point links. Establishing Connections Read More …
PPP – Point-to-Point Protocol
Point-to-Point Protocol (PPP) is a widely used communication protocol that facilitates the transmission of data over point-to-point links. It is particularly important in networking because it provides a standard method for transporting various types of data, including IP packets, over direct connections between two devices. Understanding PPP is essential for new networking students, as it Read More …
ICMP – Internet Control Message Protocol
The Internet Control Message Protocol (ICMP) is a fundamental protocol used in the Internet Protocol (IP) suite. It is primarily designed for network devices to communicate error messages and operational information regarding the status of the network. While ICMP is not used for transmitting data like TCP (Transmission Control Protocol) or UDP (User Datagram Protocol), Read More …
What are the advantages of FASP
The speed increases are achieved by sending larger packets than TCP, not waiting for confirmation that a packet has been received before sending the next one, and only re-sending packets that are confirmed as having been dropped. FASP (Fast and Secure Protocol), used in IBM Aspera, offers significant advantages for cloud data transfer, enabling faster, Read More …
BGP: The Backbone of Internet Routing and Its Security Challenges
In the vast and interconnected world of the Internet, one of the most critical protocols ensuring the flow of data is Border Gateway Protocol (BGP). BGP is the routing protocol that enables different autonomous systems to communicate and exchange routing information. Without BGP, the Internet as we know it would not be able to function, Read More …
GRE Tunnels in Modern Networking
In the world of modern networking, flexibility, security, and efficiency are paramount. As the Internet continues to evolve, so do the methods by which data is transmitted across complex infrastructures. One such method is the use of Generic Routing Encapsulation (GRE) tunnels. In this article, we’ll explain what a GRE tunnel is, how it works, Read More …
UDP and Its Role in Online Communication
The User Datagram Protocol (UDP) is one of the foundational protocols of the internet, widely used for applications where speed and efficiency are prioritized over reliability. This article explores what UDP is, how it works, and why it is often chosen over Transmission Control Protocol (TCP) for specific use cases, particularly in online communication and Read More …
TLS: How It Protects Your Data Online
In today’s interconnected world, ensuring the security of data during online communication is essential. Transport Layer Security (TLS) is a foundational protocol that helps protect the privacy and integrity of data exchanged over the internet. This article will briefly explain what TLS is, how it works, and why it is critical for safe online communication. Read More …
DHCP and Its Role in Network Functionality
The Dynamic Host Configuration Protocol (DHCP) is an essential component of modern networking, ensuring that devices can seamlessly connect and communicate within a network. This article explores what DHCP is, why it is critical for networks to function efficiently, and how to configure basic DHCP settings on a home router. What is DHCP? DHCP stands Read More …
