Traceroute command not showing hostnames for each hop, only * * *


Traceroute command not showing hostnames for each hop, only * * *
Need I say more?

E.G.
Code:
jon_k@2[~]$ traceroute linuxquestions.org
traceroute to puretna.com (64.69.71.83), 30 hops max, 38 byte packets
 1  * * *
 2  * * *
 3  * * *
 4  * * *
 5  * * *
 6  * * *
 7  * * *
 8  * * *
 9  * * *
10  * * *
11  * * *
12  * * *
13  * * *
14  * * *
15  * * *
16  * * *
17  * * *
18  * * *
How can I get a view that would be similar to this:
1 hop1.dns [10 ms]
2 hop2.dns [34 ms]
3 hop3.dns [32 ms]

Knowing which hop# my connection fails on is of little use to me if I don't know the address/ip of the failed hop.

I've tried several traceroute packages, they all show this form of output.
Thanks.

The * means there was no response for 5 seconds.

Try this, it will wait 30 seconds before giving you a *
Code:
traceroute -w 30 www.linuxquestions.org
Hmm I wonder if not having the www in front might be hanging it up too....

Nope. It seems to just take longer now... but same results.

Could it be that my ISP isn't functioning properly? Been like this for as long as I can remember. Just never questioned about it until now..

Is it the DNS of my ISP? I have several other DNS servers I can use for my connection. Or maybe something in Linux configured incorrectly dealing with DNS?

Any replies appriciated -- thanks!
Code:
jon_k@1[~]$ traceroute -w 30 www.linuxquestions.org
traceroute: icmp socket: Operation not permitted
jon_k@1[~]$ su

Could be a problem with ISP, or could be a firewall issue. traceroute uses ICMP and that may be filtered out somewhere, either your machine, your ISP, or the machine hosting linuxquestions.org

The good news is that it appears DNS is working fine for you, when you put in www.linuxquestions.org it returned the proper IP address.
