Scenario 6: The Evolution of the Internet User Interface

You can also configure NAT manually using the Routing and Remote Access MMC snap-in. This is the only way to configure a NAT server on a machine that already has RRAS enabled. RRAS can perform NAT along with its other functions, which include acting as a network router or accepting dial-up network connections. In Figure 3.15, the traffic within the Broadcast Video class is assigned to a nonstrict-priority queue with adequate guarantees. Here we see that the queue has adequate bandwidth guarantees and does not have any WRED (early packet drop), which can impact IPTV and other types of broadcast video applications.

The new ones are based on hardware locations like enp3s0 and wlp2s0. There are multiple ways to configure the network in modern Linux systems. However, sometimes we need to do it manually using the /etc/network/interfaces configuration file.

Understanding and Configuring Linux Network Interfaces

In this article, we’ve covered what a network interface is and what its different types are. The network card operates as a middleman between a computer and a data network. For example, when a user requests a webpage, the computer will pass the request to the network card, which converts it into electrical impulses. The fundamental difference between UDP and TCP is that UDP offers unreliable data transfer. It does not verify that data has been received on the other end of the connection. Usually ICMP packets are transmitted when a different kind of packet encounters a problem.

Destination IP address of the VPN server’s perimeter network interface and UDP destination port of 4500 (0×1194). Destination IP address of the VPN server’s perimeter network interface and UDP destination port of 500 (0×1F4). That entry means every time this system boots, it will collect its network information from the DHCP server. But remember, the system doesn’t store those numbers in the file–it keeps them in RAM and sets the configuration of the network interface every time the system boots. The installer has automatically identified the one ethernet interface available and selected it for configuration. The text next to the selected interface is the system name of the interface, connection state, hardware address (found from the system, we don’t enter that) and speed (also found from the system).


Using NetworkInterface, you can specify which NIC to use for a particular network activity. Now it works – but of course, NOT with the both connections active, but only with the Ethernet disconnected. In this blog, we will learn what is data encapsulation in the computer network. We will also see the encapsulation and de-encapsulation process in the OSI and TCP/IP models.

  • If the network drops a single video packet, there is a visible degradation of video quality of anywhere from a single frame up to a loss of 1 second of video, depending on the kind of encoded information that is lost.
  • Destination IP address of the VPN server’s perimeter network interface and UDP destination port of 500 (0×1F4).
  • RRAS is installed with Windows Server 2003 but is not enabled by default.
  • Networks can be linked together, but traffic must be routed when crossing network boundaries.
  • While there are multiple ways to configure a network, we’ve seen just one of them here.
  • You must specify them using the Properties dialog box for the network interface.

“People in airports and grocery stores who talk to themselves using those stupid looking knobs in their ears are already annoying. Imagine an office where people in cubicles are all talking to themselves—composing proposals, sending e-mails, making notes on their next presentation to the boss. Some noted that those with special needs are most likely to use speech-recognition UIs first.

A WoT Testbed for Research and Course Projects

The except access-list keyword and argument exclude particular groups or channels from counting toward the IGMP cache limit. An IGMP membership report is counted against the per-interface limit if it is permitted by the extended access list specified by the except access-list keyword and argument. To transmit or receive data packets using an SDR-based application, the packets transverse various hardware and software layers initiating from high-level GNU Radio application to low-level physical mapping. Once IIS is installed on Windows Server 2003, it is locked down to prevent any unneeded services from being exploited. If dynamic content is used on the server, you will need to enable the necessary features.

It implements the physical layer circuitry necessary for communicating with a data link layer standard, such as Ethernet or Wi-Fi. Each card represents a device and can prepare, transmit and control the flow of data on the network. In datacenters with private networking enabled (including DigitalOcean Droplets), your VPS will have two networking interfaces.

Consequently, it might be difficult to qualify a DSL line at the time of installation to ensure a BER of less than 10−10 over the life of the video service. They become the Internet’s interface to the physical world by converging the physical world into digital world [3,4]. With a partial lack of efficient and scalable communication standards, the number of devices connected to the Internet will increase rapidly as soon as IP becomes the core standard in the field of embedded devices. The IoT and the WoT address this challenge by using IP and IPv6 (6LoWPAN) for embedded devices [6].

If it’s a separate network card expansion card (not onboard), it usually is on the back of the computer, near the bottom, taking up a PCI slot. Try checking Edit ▸ IPv4 Settings ▸ Routes ▸ Use this connection only for resources on its network on the two LAN connections to prevent them from becoming the default gateway. We will also see the application and features of using pipelining in computer networks. If you click on IPv4, you can see that your old familiar numbers were given to your network interface by DHCP. There’s the ON/OFF button again, and in this case, it’s in the ON position. Choosing the gear button displays the network numbers that have been assigned (still DHCP) to the network interface.

ways to configure a network interface in Linux

NFS is a client/server application, communicating with a remote procedure call (RPC) based protocol. It enables file systems physically residing on one computer system or NAS device to be used by other computers in the network, appearing to users on the remote host as just another local disk. NFS is a client/server application, communicating with a remote procedure call (RPC)-based protocol.

This is a way for the two ends of the communication to acknowledge the request and agree upon a method of ensuring data reliability. The IP protocol is one of the fundamental protocols that allow the internet to work. IP addresses are unique on each network and they allow machines to address each other across a network.
