Linux - Improving Traceroute Output
Usually when I use traceroute without any options, it gets stuck showing output like this:
14 * * *
15 * * *
16 * * *
For more info about why this is happening: Link
To improve this output, try adding -I (traceroute -I) to make it use ICMP ECHO instead of UDP for probes.
If you want better statistics about packet loss, you can also use a tool called mtr which combines traceroute and ping. If you’re on Ubuntu, you can install this with sudo apt-get install mtr.
