I have installed traceroute in my ubuntu 18.04. Now when I want to trace a website's ip route then in the first line it shows a ip (may be my ip address) but in the fext following address it prints only stars instead of ip address. But it works fine on windows pc.

In my ubuntu 18.04LTS 

mefahimrahman@Night-Fury-P452LA:~$ traceroute google.com
traceroute to google.com (172.217.160.142), 30 hops max, 60 byte packets

But in windows pc it gives:

C:\Users\Aurangzeb>tracert google.com

Trace complete.

How can I get expected result in my ubuntu OS?

    I suspect it's because `traceroute` is using UDP probe packets by default - and your firewall settings are blocking them. IIRC Windows `tracert` uses ICMP - so you could try `traceroute -I` or `traceroute --icmp` (but it requires elevated privileges i.e. may need to be run using `sudo`) – steeldriver Jan 29 '19 at 14:21
  • @steeldriver thank you it works fine for **sudo traceroute -I** but **sudo traceroute --icmp** is not working. – mefahimrahman Jan 29 '19 at 14:34

    That's odd - `-I` and `--icmp` should be the exact same options. What is your traceroute version (`traceroute --version`)? – steeldriver Jan 29 '19 at 14:40

    It's also worth mentioning most modern Ubuntu systems use `traceroute6` or `tracepath` which are technically different than `traceroute` - although I agree with @steeldriver the `-I` and `--icmp` should be the same. – Kristopher Ives Jan 29 '19 at 14:49
  • Yeah, finally it works!! After restarting my pc both commands are working fine. Thank you @steeldriver – mefahimrahman Jan 29 '19 at 15:06
  • @steeldriver Add your comment as an answer. – MatsK Jan 29 '19 at 18:25
