  1. Learn how to use traceroute on Linux to identify the slowest hops in a network connection and troubleshoot sluggish network problems. Find out how traceroute works, how to install it, and how to customize its options.

    • -4 Option: Use ip version 4 i.e. use IPv4 Syntax: $ traceroute -4 google.com.
    • -6 Option: Use ip version 6 i.e. use IPv6 Syntax: $ traceroute -6 google.com.
    • -F Option: Do not fragment packet. Syntax: $ traceroute -F google.com.
    • -f first_ttl Option: Start from the first_ttl hop (instead from 1). Syntax: $ traceroute -f 10 google.com.
    • Configure wait time. The default wait time in traceroute is 3 seconds meaning it will wait for 5 seconds before jumping to the next one. And if you want to change the defaults, you can append the number of seconds with the -w option
    • Change the number of packages sent/received. By default, traceroute sends 3 packages for a hop and if you want to change this behavior, you will have to use -q option.
    • Specify the maximum number of hops. The default maximum number of hops for a single query is 30 in traceroute which can be extended to 255. For that, you can append the max number of hope with -m option
    • Specify with what TTL to start. By default, the traceroute will start with the first TTL but you can change this behavior using -f option. For reference, I wanted to start tracerouting on google's domain from the 5th TTL so had to use the given command:]

    • Trace the route to a network host. You can specify the domain name or IP address to trace the route to a network host. The following example prints the route taken by packets to reach the host www.golinuxcloud.com.
    • Trace the route using IPv4. The -4 option enables only IPv4 tracerouting to a network host. $ traceroute -4 www.golinuxcloud.com. Sample Output
    • Trace the route using IPv6. The -6 option allows you to use IPv6 protocol to trace the route to a network host. $ traceroute -6 gtraolinuxcloud.com. Sample Output
    • Use ICMP ECHO. By default, the traceroute command uses the UDP ports for tracerouting. To use ICMP ECHO instead of UDP, run the command with -I option.
  4. Aug 11, 2021 · Traceroute is a command-line utility that prints the route (or hops) that a packet takes to reach another host. It is used for network diagnostics. As its name suggests, the primary purpose of a traceroute is to trace the IP route from a source to a destination inside an IP network, allowing administrators to resolve connectivity issues better.
