OK, got it

how about this, I just got my DNS account and checked the settings which are OK as far as I can see, but when trying to use it I only get Looking up xenonlyse.se... in my FF browser and when I ping from work(which is the few that can do that and get an answer) I only get: Ping request could not find host xenonlyse.se

I can't even see anything in my iptables log
I tried a 'tracert' (windows) and that didn't get anything out.
Can you see anything that's wrong with this picture...

The resolution looks good but I can't ping the address you're pointing to:

DNS A record looks good:

I've seen an ICMP in my firewall starting with a 9.... Ill open that up and you can try again. Normally I drop all ICMP.

did you ping through the name or by IP?
I can't ping by name at all, I don't even see the drops in my firewall log

Void Main · Post by **Void Main** » Wed Feb 11, 2009 3:05 pm

As you can see in my previous post I tried both and the name resolves to an IP. If you are dropping ICMP then that would explain why I can't ping it. Here is a better test, you don't have to change your firewall settings:

Code: Select all

my dig sure looks different

It obviously hasn't propagated out to all DNS servers. Either that or your local DNS servers are broken and are not properly querying the root servers.

Basher52 · Post by **Basher52** » Wed Feb 11, 2009 3:32 pm

In that case I believe the last thing cos it can't take this particular domain name over 2 hours, when it take no-ip changes to take affect like 30 seconds later.
btw it can't be that either since work isn't using the same dns servers

Void Main · Post by **Void Main** » Wed Feb 11, 2009 3:44 pm

It may not have made it out to all the root servers yet. It made it out to the ones I queried so give it a day and see what happens.

Basher52 · Post by **Basher52** » Wed Feb 11, 2009 3:57 pm

that's kinda funny, cos about a week ago when I called them and asked them to point the domain to this address and started to work after 6-7 minustes.
Too bad though 'cos later when I asked them to do the MX Records too they saw that the account didn't imply the DNS service so they removed it.
So how come it can take a day this time and only minutes that time?
Sounds weird to me, ah well I'll wait and see.

Void Main · Post by **Void Main** » Wed Feb 11, 2009 5:37 pm

I can't answer that. I have no control over DNS root servers. You can check yourself though. Like I said, it's resolving for me so at least some of the world knows your domain name. Here's a trace:

From my perspective everything looks good so as far as I can tell it has to be something on your local DNS servers causing the problem, or it hasn't propagated to all the root servers as I said before. Your domain provider does not have control over the root servers. They get reloaded periodically (I don't think every more than a 24 hour span though).

Basher52 · Post by **Basher52** » Thu Feb 12, 2009 1:18 am

OK, that I can get. It works at home now but not from work yet.

But how does no-ip work then? If I make a change there it works in like 30 seconds everytime.

Void Main · Post by **Void Main** » Thu Feb 12, 2009 7:00 am

You are not adding a new domain when you add a record with no-ip, you are just adding a new host to an existing domain. The root servers already know which DNS servers are responsible for all of the no-ip domains and those no-ip DNS servers are reloaded with the new information much more often than root servers get reloaded. Entirely different situation.

Also, *.se top level domains are handled by a different set of root servers than *.com, *.edu, *.org (and most ofther top level domains). They would likely be reloaded on a completely different schedule.

Having said that your servers at work may be misconfigured or having some sort of problem. You might want to bring it up to whoever administers them to trouble-shoot the problem.

There is likely a FAQ on that page where you manage your DNS that would say how soon you could expect the root servers to be updated when you add or change your domain. I can't read Swedish so. :)

Void Main · Post by **Void Main** » Thu Feb 12, 2009 7:12 am

I just did a dig against all the .se servers and they all know about your domain so if you can not resolve that domain at work then it is most certainly an issue with your local DNS server. Contact your administrator. Let me guess, you run Microsoft DNS at work right? ;)

Who runs 164.9.196.5 which is the server you seem to be pointing to?

Basher52 · Post by **Basher52** » Thu Feb 12, 2009 7:13 am

yes they do
