traceroute
traceroute is a tool to trace the path of an IP packet as it traverses routers, and it is a great utility for checking the route from a source to a destination. The traceroute command is one of the simplest yet most effective ways to troubleshoot network problems.
NOTE:
- Different platforms offer traceroute as a tool, such as TRACERT on Windows or TRACEROUTE on Linux and Mac.
- Installation steps on both platforms are pretty simple, since we will be talking about Linux (Ubuntu). Below are the steps to get this utility installed.
- If you are on RHEL family, you can get this installed by
yum.
$ apt-get update -y
$ apt get install traceroute -y
Here are some examples of how to use the traceroute command in Linux:
To perform a traceroute to a host:
$ traceroute google.com
To perform a traceroute to a host with the IP address:
$ traceroute 142.250.77.78
To perform a traceroute with a maximum of 10 hops:
$ traceroute -m 10 google.com
To perform a traceroute with a maximum wait time of 2 seconds per hop:
$ traceroute -w 2 google.com
To perform a traceroute with only one packet sent per hop:
$ traceroute -q 1 google.com
Feel free to check its capabilities via man traceroute
