$ tcptraceroute ${host} -f ${first_ttl} -m ${max_ttl}

try on your machine

The command "tcptraceroute" is a network diagnostic tool that traces the path taken by TCP packets from the source to the destination. It works similar to the traditional "traceroute" command but uses TCP instead of ICMP.

Now, let's break down the given command:

tcptraceroute: It is the name of the command that executes the tcptraceroute tool.

${host}: It is a placeholder for the variable "host". You need to replace it with the specific hostname or IP address of the destination you want to trace the route to.

-f ${first_ttl}: The "-f" flag specifies the first time-to-live (TTL) value to start the trace. TTL indicates the maximum number of network hops (routers) a packet can make before it is discarded. "${first_ttl}" is another placeholder for the variable "first_ttl". You need to replace it with the desired starting TTL value.

-m ${max_ttl}: The "-m" flag indicates the maximum time-to-live (TTL) value to stop the trace. "${max_ttl}" is a placeholder for the variable "max_ttl". You need to replace it with the desired maximum TTL value.

To use the command, you replace "${host}" with the target host (destination) you want to trace the route to, "${first_ttl}" with the desired starting TTL value, and "${max_ttl}" with the desired maximum TTL value.
