I have a server that I configured using zoneedit. Upon running "traceroute" on it I notice that it takes more than 100 hops.

  • How do I lower the number of hops?
  • Is this really that bad or am I too paranoid?
  • Would the nameserver play a role in the number of hops.

Over 100 hops indicates that there is a problem somewhere, or that you don't have access to a segment of the path.

Do you get * * * or repeated IP addresses?
Try with the -m option to limit the number of hops to a number < 100

  traceroute -m 90 mydomain.tld

thus you should get at least some indications about what is going wrong.

ring0 thanks for your response. – Santosh Sep 23 '10 at 17:10
It is all '* * *'. I had tried with default of 30 and later increased it to 100. Would the nameserver of the server make a difference? We currently use zoneedit and if I wanted to make our server easily findable to lower the latency what would I need to do? – Santosh Sep 23 '10 at 17:13

It seems the hops you see are actually blanks * * * because there is a firewall or router that prevents the trace to go further. Not a real problem. I don't think the DNS is related to that - DNS is used at first to get the IP of the server / domain you want. You shouldn't worry much. – ring0 Sep 23 '10 at 23:33

ring0: Correct, DNS is not the issue here. There is a firewall or a router blocking icmp requests along the way. – pauska Sep 24 '10 at 4:57

Try using tcptraceroute (or similar) with a destination port of 80 (or any other port you might think be open on the remote server) and see how that goes.

Like ring0 said above, this is not a DNS issue - it's a router or a firewall "out there" who blocks standard traceroute packets (icmp).
