What port does traceroute use in Linux?

On Linux, tracepath is a utility similar to traceroute, with the primary difference of not requiring superuser privileges.

If the target server is reached, the ICMP Code 0, Echo Reply will be sent and thus Traceroute knows the job is finished. In this case the target server is reached well before the maximum hop counts. So what we saw is a successful traceroute attempt. No issues at all !

How does Linux traceroute work?

traceroute usually works by sending a series of ICMP echo request packets to a destination. First series of messages has a Time to Live (TTL) parameter set to 1, which means that the first router in a path will discard the packet and send an ICMP Time Exceeded message.

What is the ping port number?

How traceroute works step by step?

A traceroute works by sending Internet Control Message Protocol (ICMP) packets, and every router involved in transferring the data gets these packets. The ICMP packets provide information about whether the routers used in the transmission are able to effectively transfer the data.
