Traceroute Implementation on Python

In Network information discovery, the traceroute tool is a fundamental utility in a Linux environment. Although the tool is already developed for the command line utility, we can still make our own Traceroute tool using Python language. We will explore the fundamentals of ICMP (Internet Control Message Protocol) and utilize Python's socket programming. So in this article, we will see the detailed implementation of the Traceroute tool in Python Language.

What is Traceroute?

Traceroute is a command-line utility in Linux that provides a detailed analysis of the route data packets take from the source to a specified destination on a network. By sending a series of Internet Control Message Protocol (ICMP) or User Datagram Protocol (UDP) packets with increasing Time-to-Live (TTL) values, Traceroute reveals the successive network hops, or routers, that the packets traverse. As each packet reaches its TTL limit, an ICMP " Time Exceeded " message is sent back, allowing Traceroute to identify and display the IP addresses and response times of each intermediary node. This information is invaluable for diagnosing network issues, assessing latency, and understanding the specific path data follows across the Internet.

Why to use the Traceroute Tool?

A Traceroute tool is a valuable network diagnostic tool that helps to understand the actual path through which the data is passed from source to destination. Some of the reasons to use the Traceroute tool are stated below.

Identify Network Hops: Traceroute reveals the path that packets take from the source to the destination. It displays the IP addresses of each router or hop along the route.
Diagnose Latency Issues: By showing the round-trip time for each hop, traceroute helps identify where latency or delays occur. This information is crucial for diagnosing slow network connections.
Detect Packet Loss: Traceroute can identify routers or links where packet loss is occurring. This is important for understanding and resolving issues that may impact the reliability of a network connection.
Verify Routing Paths: It allows you to verify whether the packets are taking the expected path to the destination. Unexpected routes could indicate routing misconfigurations or network issues.

Working of Traceroute Tool

The working Traceroute Tool can be broken down into 7 different steps which are listed and described below:

Initialization: Traceroute begins by sending a packet to the destination with a Time-to-Live (TTL) set to 1.
Packet Transmission: The packet is sent to the destination. The first router encountered decrements the bto 0, discards the packet, and sends an ICMP Time Exceeded message back to the source.
First Set of Results: The source records the round-trip time for the first hop and the IP address of the first router. Another packet is sent with a TTL of 2.
Iterative Process: Steps 2 and 3 are repeated, increasing the TTL with each iteration. This reveals successive routers along the network path.
Destination Reached: When a packet reaches the destination, the destination sends an ICMP Echo Reply back to the source.
Recording Information: Round-trip time and IP addresses are recorded for each hop along the route.
Output Presentation: Traceroute compiles and displays the recorded information, presenting the route to the destination with associated round-trip times.

Prerequisites:

Linux Environment: This tutorial assumes you are working in a Linux environment. The provided instructions and script are tailored for Linux systems.
Terminal Access: You should have access to a terminal or command-line interface on your Linux system. Most Linux distributions provide this by default.
Python Installed: The provided script in the tutorial uses Python. Python is commonly pre-installed on many Linux distributions.

Creating the Python Script

In this section, we will develop the Python Script for Traceroute. We will break down the script into multiple steps to ease the understanding of implementation.

Step 1: Importing Libraries

Firstly, we need to import all the essential libraries required for various functionalities. Below are the libraries that we will be using for Traceroute implementation.

socket : For DNS resolution.
struct : For packing and unpacking binary data.
time : For time-related functions.
scapy : A Packet manipulation library.
argparse : For parsing command-line arguments.

Step 2: Developing Traceroute Function

Here, the traceroute function performs the below operations:

destination_ip = socket.gethostbyname(destination) : Resolves the destination host to its IP address using DNS.
port = 33434 : This is the default destination port for traceroute. The choice of this port is arbitrary but commonly used.
The function then enters a loop, incrementing the TTL for each iteration, and sends UDP packets to the destination using Scapy.
The script interprets the responses and prints information about each hop or timeout.
The script increments the TTL for each iteration and breaks out of the loop when the destination is reached or the TTL exceeds the specified maximum hops.

Step 3: Main Function with Argument Parsing

In this step, we will develop the main function with the input argument passing to the script.

The main function performs the below operations:

Argument Parsing : This part utilizes the argparse library to parse command-line arguments. It defines three arguments: destination (the target host or IP address), max-hops (maximum number of hops), and timeout (timeout for each packet).
Printing Information : The script prints a user-friendly message indicating the destination, maximum hops, and timeout values.
Calling Traceroute Function : It then calls the traceroute function with the provided arguments.

Step 4: Script Execution

The below code snippet executes the main function when the script is run directly.

Here, we are checking if the script is being run directly (not imported as a module) using if __name__ == "__main__": . If true, it executes the main function, initiating the traceroute.

Steps to create and execute Python Script

Step 1: Open the terminal window using the keyboard shortcut “ Ctrl + Alt + T “.

Step 2: Using any text editor like Vim , vi, or Nano , open a new blank file in the text editor.

Step 3: We need to write the script below in the created file tracerouteTool.py .

Step 4: Install the scapy package by executing the below pip command in the terminal command:

Step 5: Now, execute the created script by running the the command with the command line input.

Explanation:

In the above command, it executes a Python script named tracerouteTool.py with the argument geeksforgeeks.org and the maximum hops set to 10 (-m 10) .
The script simulates a traceroute to ' geeksforgeeks.org ', displaying the route with each hop, round-trip time, and corresponding IP address.
The output displays the network path taken to reach the destination IP address (8.8.8.8) in a maximum of 10 hops.

Frequently Asked Questions (FAQs)

Q1. Why does Traceroute use UDP?

Traceroute uses UDP (User Datagram Protocol) by default because it doesn't establish a connection like TCP. UDP allows the traceroute program to send packets without waiting for acknowledgment, which is essential for the quick and lightweight probing of network hops.

Q2. What is the use of port 33434 in Traceroute?

Port 33434 is the default starting port for the UDP packets in a traceroute. The choice of this port is somewhat arbitrary but commonly used. As the packets traverse the network, the destination port is incremented with each hop, providing a distinctive identifier for each packet.

Q3. Why does Traceroute increment the Time-to-Live (TTL) field?

The Time-to-Live (TTL) field in the IP header is used to limit the lifetime of a packet. In traceroute, the TTL is initially set to 1, and with each hop, it is incremented. Routers along the path decrement the TTL, and when it reaches 0, the router discards the packet and sends an ICMP Time Exceeded message back. This process helps identify each hop in the route.

Q4. How does Traceroute handle firewalls?

Traceroute may encounter firewalls that block ICMP Time Exceeded messages or UDP packets. In such cases, it might not receive the expected responses. Firewalls can affect the accuracy of traceroute results, and some networks intentionally block or limit ICMP traffic for security reasons.

Q5. What are common issues causing incomplete Traceroute results?

Incomplete traceroute results can be caused by various factors, including firewalls, routers that don't decrement TTL, or routers configured not to generate ICMP Time Exceeded messages. Additionally, some networks prioritize certain types of traffic, affecting the responsiveness of traceroute probes.

In conclusion, the provided Python script offers a custom implementation of the traceroute functionality. It consists of raw sockets and ICMP/UDP protocols to simulate the traceroute process, showcasing the network path to a specified destination, ' geeksforgeeks.org ' in the above example. The script displays standard traceroute output format, presenting a detailed view of each hop, round-trip times, and corresponding IP addresses along the route. By combining Python's socket and struct modules, the script provides a practical and informative tool for network diagnostics and analysis, contributing to the understanding of data packet traversal through different routers in a network.

Computer Networking – Assignment 5

Lab 5: ICMP Traceroute Lab In this lab you will learn how to implement a traceroute application using ICMP request and reply messages. The checksum and header making are not covered in this lab, refer to the ICMP ping lab for that purpose, the naming of most of the variables and socket is also the same.

Traceroute is a computer networking diagnostic tool which allows a user to trace the route from a host running the traceroute program to any other host in the world. Traceroute is implemented with ICMP messages. It works by sending ICMP echo (ICMP type ‘8’) messages to the same destination with increasing value of the time-to-live (TTL) field. The routers along the traceroute path return ICMP Time Exceeded (ICMP type ‘11’) when the TTL field becomes zero. The final destination sends an ICMP reply (ICMP type ’0’) messages on receiving the ICMP echo request. The IP addresses of the routers which send replies can be extracted from the received packets. The round-trip time between the sending host and a router is determined by setting a timer at the sending host.

Your task is to develop your own Traceroute application in python using ICMP. Your application will use ICMP but, in order to keep it simple, will not exactly follow the official specification in RFC 1739.

Code Below you will find the skeleton code for the client. You are to complete the skeleton code. The places where you need to fill in code are marked with #Fill in start and #Fill in end. Each place may require one or more lines of code.

Additional Notes

You do not need to be concerned about the checksum, as it is already given in the assignment skeleton code.
This lab requires the use of raw sockets. In some operating systems (e.g. MacOS, Windows), you may need administrator/root privileges to be able to run your Traceroute program.
Local testing may require you to turn your firewall or antivirus software off to allow the messages to be sent and received. However, Gradescope is not impacted by this.
See the end of Lab 4 ‘ICMP Pinger’ programming exercise for more information on ICMP.

What to Hand in Use your GitHub repository to upload the complete code for the assignment. The name of the file you submit should be “solution.py”.

Testing the Pinger Test your client by running your code to trace google.com or bing.com. Your output should return a list and meet the acceptance criteria format provided below.

Output Requirements (Acceptance Criteria) Your code must produce the traceroute output in the format provided below for Gradescope to verify your code is working correctly.

Your trace must collect hop number, roundtrip time (rtt), host ip, and the hostname. If a hostname is not available for a host, you should provide an explicit hostname as “hostname not returnable”. Also, if a host is timing out (not responding), you must record this in your trace list item with the text “Request timed out”. Example provided below:

Example: 1 12ms 10.10.111.10 hop1.com 2 30ms 10.10.112.10 hostname not returnable 3 * Request timed out 4 5ms 10.10.110.1 target-host.com

Your get_route() function must return a nested list with trace output. That is, each trace row must be a list that includes the trace results as individual items in the list, which is also inside an overall traceroute list. Example provided below:

Example: [ [‘1’, ‘12ms’, ‘10.10.111.10’, ‘hop1.com’], [‘2’, ‘30ms’, ‘10.10.112.10’, ‘hostname not returnable’], [‘3’, ‘*’, ‘Request timed out’], [‘4’, ‘5ms’, ‘10.10.110.1’, ‘target-host.com’] ]

Note: Your output will be parsed to verify that it includes the relevant information, so if you do not provide the output of your function in a nested list, your solution will not work correctly and you will not receive points. Also, note that the example lists include all data as strings.

Skeleton Code Code is available below and on Google Drive: https://docs.google.com/document/d/17WddCRB1KFY6FwzGEW4oGaG67QjYwtDNhZGWMN3Ik4M/edit?usp=sharing

Python Programming Assignment 4: Tra ceroute

In this assignment you will continue to build your understanding of IP, ICMP, and Traceroute using Python socket programming. Although published before the ICMP Pinger Python lab is due, I would highly recommend finishing that assignment before beginning this one as some of the core components and learnings are borrowed from there – e.g. the checksum and header creation is not provided, but can be referenced from the ICMP pinger.

Traceroute is a computer networking diagnostic tool which allows a user to trace the route from a host running the traceroute program to any other host in the world. Traceroute is implemented with ICMP messages. It works by sending ICMP echo (ICMP type ‘8’) messages to the same destination with increasing value of the time-to-live (TTL) field. The routers along the traceroute path return ICMP Time Exceeded (ICMP type ‘11’ ) when the TTL field become zero. The final destination sends an ICMP reply (ICMP type ’0’ ) messages on receiving the ICMP echo request. The IP addresses of the routers which send replies can be extracted from the received packets. The round-trip time between the sending host and a router is determined by setting a timer at the sending host.

Your task is to develop your own Traceroute application in python using ICMP. Your application will use ICMP but, in order to keep it simple, will not exactly follow the official specification in

Project 2 - Traceroute

Table of contents, project objectives, description, getting started, deliverables, sample output.

In this course project, you will develop a Python script that probes the route from the local machine to a given host address.

The traceroute program identifies the IP addresses of all intermediary machines in between the source and destination. A UDP-based traceroute program is discussed in the class. In this project, you will implement such a tool with the following features.

The tool must be implemented in python3 and utilize scapy for custom packet generation. Aside from the socket library, no additional libraries are allowed to be used.
The first line of the .py script must be the location of the Python3 interpreter: #!/bin/env python3
Input argument : The tool should accept a single argument - the hostname or IP address of the destination host.
Max hops : Your tool must be able to identify all IP addresses in the path with the distance less that or equal to 20 hops. (In contrast, the default limit for traceroute in Linux is 30 hops.)
Max probes : Your tool must attempt for only one probe for a node at a certain distance. (In contrast, the traceroute tool in Linux sends three probes for a specific distance by default.)
This is different from traceroute in Linux, which begins all traceroutes with destination port number 33434 and increments by 1 for each probe. That is, the first probe has destination port number 33434, the second probe has destination port number 33435, etc.
Source port number : Your tool should pick a random high number for the source UDP port for each probe. (The port fields are two bytes each in size, so don't pick a random number higher than 2 16 or 65535!)
The Linux-based tool reports the host name in addition to the discovered IP address whenever possible. This is out of scope of this project.
Your tool must stop sending probes as soon as it receives an ICMP Port Unreachable message from the target.
It is desirable to eliminate verbosity of Scapy within the tool. You may use conf.verb = 0 for this purpose.
It is desirable to report the discovered IP addresses along the path to the target in real-time fashion (similar to Linux-based tool), rather than computing a whole list of addresses up to the target and reporting them in a single burst.
At the top of the script file, briefly describe how your tool works.

As a rule of thumb, if your traceroute program output differs from the Linux-based tool to a great extent, then you are probably doing something wrong. Compare the traffic generated by your tool versus the traffic from the Linux-based tool. That may help you to tune your probing packets appropriately.

First, ensure traceroute is installed in your Linux VM:

Then, start Wireshark, capture a traceroute sequence to 8.8.8.8 (Google public DNS, a good example target), and stop capture.

Model your code against the traceroute behavior you see in Wireshark and follow the project requirements above.

Note that your traceroute from the standard Linux utility should look something like this. If you don't see network hops, and instead see line after line of * * * , then you have a networking problem in your VM that should be solved before writing your Python code. (Switching from NAT to Bridged mode in your virtual machine may help).

Submit a single Python script that implements traceroute to the Canvas CMS Project 2 assignment.

If using PyCharm, do not submit your venv environment. Before submitting, test to ensure you can run your program outside of PyCharm on the command line.

Running the tool may generate an output similar to the following in a terminal in Ubuntu Linux.

Implementing a simple traceroute clone in Python

I was watching this amazing lightning talk 1 by Karla Burnett and wanted to understand how traceroute works in Unix. Traceroute is a tool that shows the route of a network packet from your computer to another computer on the internet. It also tells you how long it takes for the packet to reach each stop along the way.

It’s useful when you want to know more about how your computer connects to other computers on the internet. For example, if you want to visit a website, your computer sends a request to the website’s server, which is another computer that hosts the website. But the request doesn’t go directly from your computer to the server. It has to pass through several other devices, such as routers, that help direct the traffic on the internet. These devices are called hops. Traceroute shows you the list of hops that your request goes through, and how long it takes for each hop to respond. This can help you troubleshoot network problems, such as slow connections or unreachable websites.

This is how you usually use traceroute :

This returns:

This traceroute output draws the path of a network packet from my computer to example.com ’s server, which has an IP address of 93.184.216.34 . It shows that the packet goes through 11 hops before reaching the destination. The first hop is my router ( 192.168.1.1 ), the second hop is my ISP’s router ( 142.254.158.201 ), and so on. The last column shows the time it takes for each hop to respond in milliseconds (ms). The lower the time, the faster the connection.

Some hops have multiple lines with different names or IP addresses. This means that there are multiple routers at that hop that can handle the traffic, and traceroute randomly picks one of them for each packet. For example, hop 7 has three routers with names starting with lag-11 , lag-21 , and lag-31 . These are probably load-balancing routers that distribute the traffic among them.

The last hop ( 93.184.216.34 ) appears twice in the output. This is because traceroute sends three packets to each hop by default, and sometimes the last hop responds to all three packets instead of discarding them. This is not a problem and does not affect the accuracy of the traceroute.

This is all good and dandy but I wanted to understand how traceroute can find out what route a packet takes and how long it takes between each hop. So I started reading blogs like this 2 one that does an awesome job at explaining what’s going on behind the scene. The gist of it goes as follows.

How traceroute works #

Traceroute works by sending a series of ICMP (Internet Control Message Protocol) echo request packets, which are also known as pings, to the target IP address or URL that you want to reach. Each packet has an associated time-to-live (TTL) value, which is a number that indicates how many hops (or intermediate devices) the packet can pass through before it expires and is discarded by a router. Yeah, strangely, TTL doesn’t denote any time duration here.

Traceroute starts by sending a packet with a low TTL value, usually 1. This means that the packet can only make one hop before it expires. When a router receives this packet, it decreases its TTL value by 1 and checks if it is 0. If it is 0, the router discards the packet and sends back an ICMP time exceeded message to the source of the packet. This message contains the IP address of the router that discarded the packet. This is how the sender knows the IP address of the first hop (router, computer, or whatsoever).

Traceroute records the IP address and round-trip time (RTT) of each ICMP time exceeded message it receives. The RTT is the time it takes for a packet to travel from the source to the destination and back. It reflects the latency (or delay) between each hop.

Traceroute then increases the TTL value by 1 and sends another packet. This packet can make 2 hops before it expires. The process repeats until traceroute reaches the destination or a maximum TTL value, usually 30. When the returned IP is the same as the initial destination IP, traceroute knows that the packet has completed the whole journey. By doing this, traceroute can trace the route that your packets take to reach the target IP address or URL and measure the latency between each hop. The tool prints out the associated IPs and latencies as it jumps through different hops.

I snagged this photo from an SFU (Simon Fraser University) slide 3 that I think explains the machinery of traceroute quite well:

Writing a crappier version of traceroute in Python #

After getting a rough idea of what’s going on underneath, I wanted to write a simpler and crappier version of traceroute in Python. This version would roughly perform the following steps:

Establish a UDP socket connection that’d be used to send empty packets to the hops.
Create an ICMP socket that’d receive ICMP time exceeded messages.
Start a loop and use the UDP socket to send an empty byte with a TTL of 1 to the first hop.
The TTL value of the packet would be decremented by 1 at the first hop. Once the TTL reaches 0, the packet would be discarded, and an ICMP time exceeded message would be returned to the sender through the ICMP socket. The sender would also receive the address of the first hop.
Calculate the time delta between sending a packet and receiving the ICMP time exceeded message. Also, capture the address of the first hop and log the time delta and address to the console.
In the subsequent iterations, the TTL value will be incremented by 1 (2, 3, 4, …) and the steps from 1 through 5 will be repeated until it reaches the max_hops value, which is set at 64.

Here’s the complete self-contained implementation. I tested it on Python 3.11:

Running the script will give you the following nicely formatted output:

A simple traceroute(8) implementation in Python

traceroute(8) is one of these tools that sysadmins often use when a networking issue arises and needs troubleshooting.

The traceroute(8) tool is used to trace the route packets take in a network to a destination host. The tool is used to diagnose possible problems in the network and also measure the latency between systems.

The way that traceroute(8) works is by sending a sequence of UDP ICMP Echo Request packets to a destination host with a specified Time-To-Live (TTL) value.

Each time a packet reaches a gateway, the gateway checks if the TTL of a packet is greater than one, reduces the TTL of the packet by one and transmits the packet to its next hop. If the TTL of a packet is one, then the gateway discards the packet and sends back a Time exceeded response to the source client informing it that the destination host could not be reached as the packet TTL has exceeded.

These Time exceeded responses are then being used by the source client to determine the intermediate gateways sitting between the source and destination system by manipulating the TTL of packets on each iteration until we finally reach our destination host or the max number of iterations (hops limit) has been reached.

You can read more about traceroute(8) at the Traceroute page on Wikipedia .

Below you can find a Python module that creates a very basic implementation of traceroute(8) .

Please also note, that the receiver socket used in the class below is a raw socket ( socket.SOCK_RAW ), so you will need root privileges when binding it.

You can also find the code below in the pytraceroute repository on Github.
