Does any one have any idea how can i extend my ethernet cable beyond 100 meters between my computer and router/modem? According to my knowledge is concern the maximum size of an ethernet cable length comes around 100 meters. So ant information related to this issue would be appreciated.

You can extend your ethernet cable beyond 100 meters by adding a switch or a hub in between of both ends.

You can also opt for Ethernet Extenders. Ethernet Extenders are also known as network extenders which are used to extend an Ethernet segment beyond its normal distance limitation of 100 meters.

Recently I connected my Laptop & my PC via a straight ethernet cable. I used the ip adress 192.168.1.2, subnet mask 255.255.255.0, default gateway 192.168.1.3 for my PC & 192.168.1.3, subnet mask 255.255.255.0, default gateway 192.168.1.2 for my Laptop. At first when I need to backup my data to PC, Both system behaved well connected & I transfered all my data to PC. But after formatting my laptop when I try to transfer data again to my Laptop from my PC, it doesnt work any more. Actually it connects for only some 30 secs- 1 min & at the middle of transfer the conection breaks. It shows the message that it couldnt find the network path. I disabled my Antivirus firewall & my windows firewall both, but still the problem persists. somebody pls help..

Connecting two computer’s without a switch or hub, needs a Cross cable and not a straight cable… Also try to crimp the RJ45 connectors again, seems a bit loose… Also give only IP address and subnet mask, Gateway is not required. Will not do any harm but still… All the best!

In situation where I have access to one ethernet cable between two end points, is there a way to multiplex so it functions like two independent (lower bandwidth) ethernet cables? Perhaps some sort of multiplexer sitting at both end points, each with three ethernet ports, one goes to the cable, two others are the virtual cable end points.

A network switch is a broad and imprecise marketing term for a computer networking device that connects network segments.The term commonly refers to a Network bridge that processes and routes data at the Data link layer (layer 2) of the OSI model. Switches that additionally process data at the Network layer (layer 3 and above) are often referred to as Layer 3 switches or Multilayer switches.Not necessarily. You can buy physical cable splitters which enable you to run two 10/100 Mbps Ethernet links (each link only needs two pairs) on one regular four pair Ethernet cable. No switch, no power needed. Caveats: Obviously will not work for GigE, which uses all four pairs. May or may not work for 10/100 Mbps Ethernet, depending on distance, cable qualityA network switch is a broad and imprecise marketing term for a computer networking device that connects network segments.The term commonly refers to a Network bridge that processes and routes data at the Data link layer (layer 2) of the OSI model.

Networking security tools such as FortiGuard Web Filtering are a vital component of any modern business plan, at least for a company that relies on computer systems. These security devices and services ensure that all the vital information and data systems that keep organizations up and running are safeguarded from threats and attacks. Certain services, such as Fortinet Analysis & Management, make networking security much more convenient for modern business owners and organizational administrators. With this service, clients get a central management system without having to buy or maintain equipment, plus the benefit of skilled professionals comparing configuration policies and tracking policy changes. Analysts also provide support and reporting on security. Additional features include web browser-based user interfaces, secure data transmission and access, reliable service through hosted systems and the option to manage firmware updates in real-time or on a schedule. Protecting networks against spam, malware and other threats that appear in email messages is also crucial for modern businesses. This is why tools such as Fortinet FortiMail appliances are so useful. These security devices offer messaging security for any size and type of organization with features such as an inbound filtering engine that blocks spam and malware before it can clog the network and hinder workflow. FortiMail’s outbound inspection technology also prevents outbound spam or malware that could cause other antispam gateways on the other end to blacklist users that were unaware of threats in their outgoing emails or attachments. Organizations like schools, libraries, government agencies and enterprise businesses of all sizes often rely on services like FortiGuard Web Filtering. This service helps block access to harmful, inappropriate and dangerous websites that may contain phishing and charming attacks, malware such as spyware or questionable content. Without the right networking tools, from Fortinet Analyses & Management to Fortinet FortiMail, computer systems are always going to be at risk of attack. This is why businesses and organizations take the steps to prevent attacks before they happen.

Networking Security Threats

We as individuals interact with networks in our daily activities whether in the office, at home, or when we perform monetary transactions, use our mobile phones to make calls or use transport systems to get to work. Today, telecommunication and utility companies use networks to track phone, electricity or water usage and bill for it. Government agencies and organisations depend heavily on networks to communicate with their customers in areas such as credit or debit card transactions and billings. Many of our basic ways of life would be less convenient and many activities would be unfeasible without networks. Not astonishingly, network systems are criminals and intruders targets of choice, because of their potential vulnerabilities.

What makes a network vulnerable?

Connecting computer systems together is incredibly risky due to potential system misconfiguration, poor security policies and software flaws. Criminals can gain unauthorised access to remote networks. Intruders can capture transmissions between network nodes. Furthermore, linking networks enables organisations and individuals, including criminals, to communicate in ways that were not feasible before, resulting in a new set of vulnerabilities. Misuse of newly discovered vulnerabilities by intruders often catches us unaware. There is a need to keep information systems and the networks which carry the associated information or data secure.  There are many names for these, from networking security to information assurance.  The overriding set of principles are those of C I A (Confidentiality, Integrity, Availability), which are considered by many to be the tenets or principles of computer security. Digital assets include the entire network infrastructure, system application programs including data.
