How to Install traceroute command on Ubuntu 20.04 LTS

In this article, we will see how to install traceroute command on Ubuntu 20.04 LTS (Focal Fossa). Traceroute is a free and open source command line utility to trace the route packets originated from an IP network, traversing to the destination host. It traces the route by launching the probe packets with small TTL(time to live) and then listening for an ICMP "time exceeded" reply from a gateway. It is frequently used by system administrators and network administrators to troubleshoot the connection between source and destination host. It is also very easy to install in almost all the famous linux distributions. Here we will see the steps to install traceroute command on Ubuntu 20.04 LTS based systems.

c) You should have apt or apt-get utility available in your Server.

 

Step 2: Update Your Server

Before going through the steps to install traceroute command, it is always recommended to sync your installed packages version to the latest available one in the Ubuntu repo by using sudo apt update && sudo apt upgrade command as shown below.

Step 3: Install traceroute command

In the next step, you can install traceroute command from default Ubuntu repo by using sudo apt install traceroute command as shown below. This will download and install traceroute package along with all its dependencies.

cyberithub@ubuntu:~$ sudo apt install traceroute

Step 4: Verify Installation

After successfully installing the package, you can verify the installed files path by using dpkg -L traceroute command as shown below.

cyberithub@ubuntu:~$ dpkg -L traceroute

Step 5: Check Version

You can check current installed version by using traceroute --version command as shown below.

cyberithub@ubuntu:~$ traceroute --version

Step 6: Using traceroute 

Now that traceroute command is successfully installed, you can use it to trace the packet route to a destination host. Here we are checking the route to google.com server using traceroute google.com command as shown below.

NOTE:

Please note that below star(*) mark on the output shows that the device on that hop was not configured to reply to ICMP/UDP traffic and hence hiding all the information for security purposes.
cyberithub@ubuntu:~$ traceroute google.com
traceroute to google.com (142.250.182.14), 30 hops max, 60 byte packets
1 * * *
2 * * *
3 * * *
4 * * *
5 10.248.5.2 (10.248.5.2) 5.353 ms !X 5.734 ms !X 5.722 ms !X

 

Step 7: Check all the Available Options

You can check all the options available with traceroute command using traceroute --help command as shown below. More on Man Page.

cyberithub@ubuntu:~$ traceroute --help
Usage:
traceroute [ -46dFITnreAUDV ] [ -f first_ttl ] [ -g gate,... ] [ -i device ] [ -m max_ttl ] [ -N squeries ] [ -p port ] [ -t tos ] [ -l flow_label ] [ -w MAX,HERE,NEAR ] [ -q nqueries ] [ -s src_addr ] [ -z sendwait ] [ --fwmark=num ] host [ packetlen ]
Options:
-4 Use IPv4
-6 Use IPv6
-d --debug Enable socket level debugging
-F --dont-fragment Do not fragment packets
-f first_ttl --first=first_ttl
Start from the first_ttl hop (instead from 1)
-g gate,... --gateway=gate,...
Route packets through the specified gateway
(maximum 8 for IPv4 and 127 for IPv6)
-I --icmp Use ICMP ECHO for tracerouting
-T --tcp Use TCP SYN for tracerouting (default port is 80)
-i device --interface=device
Specify a network interface to operate with
-m max_ttl --max-hops=max_ttl
Set the max number of hops (max TTL to be
reached). Default is 30
