Routing completes the design of the electronic equipment and defines the lines that connect the components that make up the designed device. It includes certain steps for executing the program and stopping at commands, lines. Tracing tasks are laborious due to the variety of methods for technological implementation of connections.
Instructions
Step 1
Use a special tracing program that you probably already have on your network operating system. If it is Windows, the program is called tracert; on GNU / Linux and Mac OS operating systems, tracing can be done using traceroute. In this case, the packet information is sent to the address assigned to it. Specifically set impracticable delivery parameters, for example, the packet lifetime is too short. For the first packet, it is better to set it to one second.
Step 2
Make sure that each server located on a segment from your computer to the specified address must decrease this value by one. Thus, the packet lifetime expires immediately on the first node of the route, which will then automatically send a notification about the impossibility of delivering a packet containing data. Due to this circumstance, the tracing program will have access to information about the first intermediate node.
Step 3
Increase the life of the information package by one and try again. Now the second smart host will not be able to send it further and will be forced to send an NDR. Repeat these steps, increasing the life of the package by one each time. Using these actions, the tracing program will compile a list of all nodes contained in the interval from the computer to the destination address.
Step 4
Check the correct functioning of all intermediate points. If the program does not receive notification from one of the points, it will send a request with the following defect: the port number does not exist. When the packet returns with an error, it will indicate normal node operation. In the event that this does not happen, there is a break at the node. End the tracing program.
