Traceroute printing asterisk symbol

Question

I am trying to use traceroute unix program to find the route to a host.

I tried traceroute www.google.com and I end up seeing only asterisks printed. Examples on the internet uses the same command and it seems to work well. I tried increasing the waitime value using -w switch. Still does not work.

Well, you get your answer almost a year later. I personally was wondering the same thing, so I did some googling and found this answer on webmasters.

If a packet is not acknowledged within the expected timeout, an asterisk is displayed.

I found that traceroute -I gave more complete results.

   -I, --icmp
          Use ICMP ECHO for probes

Good! For me only with -I that this command seems to work right. Without -I, it tries until hop 30, even that the target is closer. – Topera Aug 24 '16 at 19:23
