The “traceroute<\/strong>” command tracks the path of network packets from the source to the destination. It is used to identify issues with network connectivity and detect packet loss or delay.<\/p>\n\n\n\n

The traceroute command provides insights into the number of routers between the internet source and IP and each router’s RTT or round-trip time. Here’s how the traceroute command works: it first sends the ICMP internet control message protocol packets or hops, and then the routers receive these packets along the network path.<\/p>\n\n\n\n

That’s why you can use the traceroute command for network troubleshooting to find how data packets travel from the source to the specific IP address. However, it is essential to get in-depth information about the traceroute command. Therefore, this blog has every possible detail about how to use the traceroute command in Linux.<\/p>\n\n\n\n

While traceroute comes as the pre-installed utility in many Linux distros, you can install it with the specific commands:<\/span><\/strong><\/p>\n\n\n\n

Checking whether Traceroute is installed or not:<\/h2>\n\n\n\n

You can also check the currently installed version of the traceroute command:<\/p>\n\n\n\n

traceroute --version<\/code><\/pre>\n\n\n\n

Traceroute command usage<\/h2>\n\n\n\n
Here is the basic syntax of the traceroute command you can use:<\/p>\n\n\n\n
traceroute <options> <host_IP><\/code><\/pre>\n\n\n\n
In the above command, replace <host_IP<\/strong>> with the IP address of your destination device and <options<\/strong>> with the additional options of the command.<\/p>\n\n\n\n
Let’s start with a simple example to check the connectivity between the system and the website. For example, let’s track the packets between the host and How2Shout:<\/p>\n\n\n\n
traceroute www.how2shout.com<\/code><\/pre>\n\n\n\n
With the above result, you can evaluate the packets from How2Shout’s server at a specific time. You can use the following options of the traceroute command to get crisper results:<\/p>\n\n\n\n
\"check<\/figure>\n\n\n\n
The -n<\/strong> Option<\/h3>\n\n\n\n
It disables the hostname lookup and then displays the IP address.<\/p>\n\n\n\n
traceroute -n www.how2shout.com<\/code><\/pre>\n\n\n\n
Sometimes, the traceroute command shows asterisks (*) instead of a hop. This is because those hops do not respond to the 3 queries sent.<\/p>\n\n\n\n
\"disables<\/figure>\n\n\n\n
The -m Option<\/h3>\n\n\n\n
If you want to display the N number of hops, you can use the -m option.<\/p>\n\n\n\n
traceroute -m N www.how2shout.com<\/code><\/pre>\n\n\n\n
Here, N represents the number of hops, so please replace it with the number of hops you want to display:<\/p>\n\n\n\n
traceroute -m 5 www.how2shout.com<\/code><\/pre>\n\n\n\n
\"want<\/figure>\n\n\n\n
The -I Option<\/h3>\n\n\n\n
You can use the -I option to use ICMP ECHO and check each hop’s RTT accurately:<\/p>\n\n\n\n
traceroute -nI www.how2shout.com<\/code><\/pre>\n\n\n\n
This command sends ICMP packets to the destination to obtain RTT with improved accuracy.<\/p>\n\n\n\n
\"ICMP<\/figure>\n\n\n\n
The IPv4 and IPv6 Options<\/h3>\n\n\n\n
You can use the -4 option to use an IPv4 connection during the execution of the traceroute command.<\/p>\n\n\n\n
traceroute -4 how2shout.com<\/code><\/pre>\n\n\n\n
\"Pv4<\/figure>\n\n\n\n
Similarly, use the -6 option to use an IPv6 connection in the traceroute command operation:<\/p>\n\n\n\n
traceroute -6 how2shout.com<\/code><\/pre>\n\n\n\n
\"IPv6<\/figure>\n\n\n\n
The -T Option<\/h3>\n\n\n\n
The -T option is useful when you want to identify if a particular port or TCP blocks the protocol. It specifies the traceroute command to use TCP for the process:<\/p>\n\n\n\n
traceroute -T www.how2shout.com<\/code><\/pre>\n\n\n\n
\"traceroute<\/figure>\n\n\n\n
The -q Option<\/h3>\n\n\n\n
If the load balancing has inaccurate paths, please refer to queries using the -q option. With the -q option, you can increase the amount of packets sent per hop. For instance, let’s send 10 queries per hop:<\/p>\n\n\n\n
traceroute -q 5 www.how2shout.com<\/code><\/pre>\n\n\n\n
\"amount<\/figure>\n\n\n\n
The -p Option<\/h3>\n\n\n\n
If you want to check the connectivity on the specific port, then you can use the -p option with the traceroute command:<\/p>\n\n\n\n
traceroute -p 8080 www.how2shout.com<\/code><\/pre>\n\n\n\n
In the above command, 8080 is the port.<\/p>\n\n\n\n

Save Traceroute Results<\/h3>\n\n\n\n
If you want the traceroute to save the traceroute result, then you can run the following command by which the system will save the output in the data.txt file:<\/p>\n\n\n\n
traceroute how2shout.com > data.txt<\/code><\/pre>\n\n\n\n
\"Save<\/figure>\n\n\n\n
The –help Option<\/h3>\n\n\n\n
You can check the help page of the traceroute command to go deeper into its additional options.<\/p>\n\n\n\n
traceroute --help<\/code><\/pre>\n\n\n\n
