Linux and tcp ip networking report

NOTE A loop back address is any address of the form Only the network portion of the IP address is specified, leaving the host component of the IP addresses set to zeros. Routing If two machines are connected together as a point-to-point connection over a physical connection then they can communicate between each other directly.

Linux Network Configuration

On larger networks, or those that implement special protocols or employ gateways, you need to take a few more configuration steps. Static Routing For static routes each entry in the routing table is added by using the route command. Authorisation is provided for the routers not available in RIP version 1.

TCP/IP networking reference guide

You need to set up several interfaces for your machine, including the loopback driver and the Ethernet interface I assume you are using Ethernet throughout this chapter, but you can use other interfaces.

To set the hostname, use this command: If you issue this command: Set up the Ethernet interface using ifconfig.

This is necessary to enable the local machine to find other machines.

The command and output looks like this: This is done with the ifconfig command. Another way is for one of the intermediate DNS servers to provide a recursive query, whereby it goes and queries another DNS server on behalf of the requesting DNS server.

Alternatively, you do not have to assign a domain at all for your machine, but can simply enter this short name: These work by routers constantly communicating to each other describing the network to each other. For RIP 2 then the gated daemon is stated with an empty configuration file.

If a Domain Name Server is unavailable then it would not be possible to access other machines. This limits the size of the link state database and the number of advertisements.

These steps are covered in the following sections. The loopback interface has the IP address ICMP Redirects It is possible that when a packet is sent using static routes that it will not neccessarily go the most direct route. This is measured in hops which is normally then number of gateways routers that are passed through before reaching a destination network.

Then when Sys1 next needs to send a packet to Sys21 it can send it directly to Router2. The router constructs a link state package LSP which lists its neighbours and the cost of the link.

Setting Up TCP/IP on Linux

If a computer wants to communicate with www. Setting Up the Loopback Interface A loopback interface should exist on every machine. IPv6 replaces the 32bit addressing scheme with one that is bit long, which should provide as many addresses that will ever be required.

The routing daemon dynamically learns about the network using the RIP protocol and builds its own routing tables. This is more common in routers than in host machines. Check the configuration files and route entry again and repeat the ping to the loopback address.

This is documented in RFC Sys1 then adds a route in its routing table to send any packets for Sys21 to Router2. However once we start to communicate to computers on other networks, or over the Internet then routing is needed so that the data reaches the correct destination.

After checking the ifconfig routine, you should add the loopback driver to the kernel routing tables with one of these two commands: Local Loopback inet addr For example if there are two routers on the LAN one of which goes directly to the host but the other would have to pass it to the other.

RIP uses the hop count i. Also if there is an update indicating a change in the network a router will send it immediately almost.Find helpful customer reviews and review ratings for The Linux TCP/IP Stack: Networking for Embedded Systems (Networking Series) at billsimas.com Read honest.
