I have a domain hosted on our cobalt RaQ4 server which is not accessible now. It was accessible and everything was working fine untill yesterday when suddenly no one can reach the site.

I checked the DNS record on our server and everything seems to be ok. Also the domain is pointing to our name servers when I search whois.

I do not know what happened or what is the reason for that. All other domains are working fine on the same server.

Any one knows why is this happening?

Any help is very much appreciated.

Regards,

Ahmed

Here is the dig results for this domain.


[admin admin]$ dig qld.nu

; <<>> DiG 8.3 <<>> qld.nu
;; res options: init recurs defnam dnsrch
;; res_nsend to server default -- 216.98.128.70: Connection timed out


Other domains can resolve correctly on the same server.

Now another domain has the same problem. Could it be a coinsidence? Or our name server is just leaking?

Can it be a problem with our name servers? But there are another 350 sites on the same server which are working fine with the same name servers. New sites are added everday with no problems.

I am realy confused.

I've had this problem with a domain before. DNS records correct, all *looks* well, but suddenly it stopped working, for seemingly no reason (note: DNS was not run on the same machine). I removed the DNS records, re-added them, and all was well. You may want to try that, though it doesn't explain the problem and I don't know whay it happens. As I said, this wasn't a record that was actually on the machine itself, but I'm not sure that matters.

Thank you so much Chicken. I'll try it and let you know if it works.

I did a bit of seaching in WHT, some also had the same problem but no one seemed to know what the problem is.

I'll try removing the domain and put it back again and see.

Thanks a lot.

Still the same. I removed the domain and created it again and still not reachable.

Maybe I have to wait for a while for the changes to take effect. What do you think?

Thanks.

Try rebooting the server as well as restarting the apache server and DNS Daemon.



-Omair

Thank you so much Omair. I'll try to do that. But all other domains are working fine. What will make it work if I restart the server?

If there is no any error or anything else it would stop it for a moment.



-Omair

Thank you so much Omair, but I rebooted the server and still the same.

I can access the site locally from the server using lynx. This means that the name server is working fine.

Any other ideas? There must be a reason for that.

I should have added that I just removed and restored the DNS entries for the domain, not the site itself, and yes, had to wait 24 hours for it to come up, but it did.

Thank you chicken for the addition. That is what I did, I removed the dns entries then created them again. I am still waiting and nothing changed, I hope it is back soon.

Thanks.

The only thing that came up for the domain was:

Domain Name (UTF-8): qld.nu
Domain servers in listed order:
ns.goodhosting4u.com
ns2.goodhosting4u.com

So if these are your nameservers, something isn't right still. I know that .nu charges $10 (I think) to change nameservers, but if you're willing to pay that, maybe try shifting DNS to an outside place like http://www.mydomain.com 's DNS services and see what happens?

The owner of this domain registered it at registerfly.com. He is trying to do as you suggested by using mydomain.com service, but he is unable to change the name servers to ns1 and ns2.mydomain.com, it is giving him an error and registerfly is not responding.

Maybe they need to charge him for this $10 to change the name servers?

I'm not entirely certain as to how the arrangement between registerfly and the .nu registry works. The $10 fee I mentioned only comes from this:

http://nunames.com/pricing.cfm
We also charge a nominal US$10 fee for all modifications to technical contact and name server information. There is no charge for changes to your personal information, including billing E-mail address changes.
It may, or may not, apply to domains registered through registerfly, but it seems lack of customer support from registerfly isn't helping all that much (maybe they are trying to contact the .nu registry, and if so, this may be the cause of the slowness).

Thank you chicken for your quick response.

I am realy sad that I do not know what is the cause of this problem. I hope someone knows what's wrong.

ns, ns1 and ns2.goodhosting4u.com are all registered as name servers at directnic.com. They are working fine for many other domains. And new domains are added everyday with no problems.

This problem is very strange.

I am realy confused.

350 sites on a Raq server, wonder if that could be your problem, I though the Raq was only able to handle 250 at the most.

That is way overloaded. Or are these 350 sites only using the name server?

Most of them are small web sites. Here is the 'top' results now.

5:05pm up 1 day, 2:28, 1 user, load average: 0.24, 0.27, 0.26


As you see, the load is very small. It is often as such.

You mean 250 IP-based sites. But most of them are name based.

You answered before I posted.

The cobalt program is set to read this:

http://list.cobalt.com/pipermail/cobalt-users/2001-December/058424.html

Most of them are name-based sites. Only 8 of them are IP-based which have their own dedicated IPs.

But I never had problems adding new sites. Does this have effect on the name server?

I have no idea if it does or not. I limit my raqs 150 to 170 sites because I do shared hosting.

You may want to search, join, ask these question on the cobalt users list at:

http://list.cobalt.com/mailman/listinfo/cobalt-users/

Thank you so much ljprevo for your help, I realy appreciate it. I'll try to set it as you said and see what happens.

I changed the setttings as you suggested and still the same.

Hi.
I own one of the domains which has "vanished" off the net. I must say first of all that Ahmed from Nozol has worked tirelessly for days trying to solve this problem, but it still is a mystry.

I am not sure what to do toget my domain anme running www.qld.nu and 4 other sub doamins. The name sems to be propogating but the server does not want to recognise it.

I notice some suggesting too many domains on th eserver. This is a shared hosting set up . I hope someone out there can offer some assistance. I beleive there are 2 other doamin names effected as well.

Please send a good samaritan with some news!! Thanks to thos who have made suggestions wethere they work or not , thanks for trying.

Col

I just looked at every whois site that I could find and could not find the domain listed anywhere (qld.nu) it shows as taken but internic does not seem to know about it, networksolutions same same.. It may well be a problem with your registrar. Make sure they have it pointing to the correct nameservers.

Shortness

WHups.. trash that last message.. I did find it finally...

Looking back through this thread, you mention that you have over 350 sites on this machine.. could that be the problem?

Isn't the limit set at 200 somewhere in the conf files... have you increased that amount to cover how many domains you have on there.. ??

Sorry for the confusion on the last post.

Shortness

Don't know if this helps or not but the results of a dig from my server are:

[root /root]# dig qld.nu

Shortness

Thank you shortfork. This limit is only in the addition of new sites in the control panel. It has nothing to do, in my knowledge, with the ability of the name server to handle these domains. Besides, I never got an error from the control panel when adding a new site. I also increased this limit in the configuration file to 500 as ljprevo suggested and still the problem exists.

Could you please tell us the full dig result you got for qld.nu to see if it is the same we get?

Thank you so much.

Ahmed,

Did you considered my offer?



-Omair

Thank you so much Omair. I just replied to your email.

How about setting up your computer to use your DNS server entries....

i.e. I am using AT&T RoadRunner and have a RaQ. Try setting your DNS server to the ones on your RaQ and see what happens.

Also, have you tried accessing this site from another computer on a diffent network?

Thank you so mcuh pitchford. I understand what you mean. Actually I set the dns of the raq itself to our name servers and I can access the domain normally. i.e. the name server is responding correctly, if that is what you mean.

I'll also try to set my computer to these name servers and see what will happen.

I just set the dns in my pc to our name servers. Now I can ping to the domains and they resolve correctly, but I can not access it from the web and gives 'cannot find server or dns error'. I use ie5.5. So what do you think of that?

That's what I got, other than my domain and the last default ip address, which likely has nothing to do with your machine as it's an ip on my system's block..

I'm wondering, are you running all those sites and your own DNS on the same box?

My guess is that if so, it's simply too much for the poor little blue thing to keep up with :cartman:

Good luck!

Shortblock

Thank you so much shortblock.

The load is rather small on the server. It is now,

2:08pm up 12:43, 1 user, load average: 0.37, 0.40, 0.36


I always watch the load with 'top'.

I hope this problem is solved soon.

Thank you so much, best of luck to you too.

Jumping in here!

We are having the EXACT same problem on one of our Raq4i's. Over the past 2 weeks or so one domain name has been generating complaints from some people saying the site was down. Traffic levels seem to be normal though, and the site is/was reachable for most people.

We looked at everything, it all seems "normal", we could do regular nslookup's and dig's and see the nameserver passing out the correct data to us from a different network.

NOW, I can't even get to the site by name...I have to use the IP Address. I am on an @Home connection (I would suspect THAT is the problem..but I know some of the complaints are coming from completely different networks). The strange thing is...for a time, if I had my Proxy set to be used in my browser...I could still reach the site....but not without out. Then..it reversed...and now With proxy on, I get "Bad Gateway...DNS Timeout".

Huh...I just tried it...and it's now working...with proxy on...

What I DO know is the nameservers are both on the same server, which is also hosting a VERY busy vBulletin site, and we have had to reboot MANY times over the past week. Our assumption in all this is that the server is just too busy to answer the DNS queries.

Our solution to it is we are shutting down the nameservers, and are going to use a third-party service....we find easyDNS.com works very well for that. We hope it solves the problem! (I don't see how it wouldn't). It can be a little pricey, so for this particular server...with only 5 or 6 domains on it....it's a reasonable alternative...I don't know what we'd do with 200 domains!

I'll try to keep lurking, would like to find out what is causing these problems for the site talked about in this thread...in case it's somehow related to our own problems.

GOOD LUCK!!

Thank for the Transcanada. As I own this domain and 4 subdomains off it I am very keen to get it back again. I know there are 2 other domains on this server experiencing the same problem. It vanished last Thursday .

I was wondering if I had my own namesever if this would "fix" the problem subject of course to Ahmed at Nozol agreeing to this. It is all so strange.

Maybe there are to many domain names on the server, I believ 350 but I wouldnt think so as on 3 names are known to have been effected.

Hope I wake up from this bad dream soon :D

qld.nu uses the following nameserver:

ns.goodhosting4u.com
ns2.goodhosting4u.com

The nameservers resolve to the following ip addresses:

ns.goodhosting4u.com. 22h52m12s IN A 209.126.170.87
ns2.goodhosting4u.com. 1d5h31m58s IN A 209.126.170.111

Are the above ip addresses yours? 209.126.170.87 and 209.126.170.111

It doesn't look like bind is running on these two ip addresses. Port 53 looks to be closed. That could be your problem.

Look at the following which works correctly.

Excellent Mike. Thank you so much. I think this is logic. How to open the port for these two ips? They are on the same machine as 209.126.170.250

Thanks.

By default, your nameserver should listen on all ip addresses that have a website assigned via the GUI. Did you add any custom software?

no I did not.

Thank you so much Omair for your efforts. You are realy so helpful.

Thanks a lot for all of you who sent replies.

I hope the problem is resolved soon.

I too would like to thank all you guys for you input in helping to solve this problem. Every bit of info will help in the long run to help solve this problem.

I know Omair has been doing some background work with Ahmed in trying to get to the bottom of this, thanks to you guys who I have never met.

Arohanui Col Heke

Great news!! Great news!!

Weeeeeeeee!!!!


Finally everything works fine now. Thank you thank you thank you so much all of you.

Special thanks to mike who opened the door for the solution.

Here is how it is solved. Just added the following line to named.conf in the options part.

listen-on port 53 { 209.126.170.250; 209.126.170.111; };

Now it is all working fine.

Thank you so much all of you :)

Thanks so much all of you, to Mike for his part is putting his finger on the problem and to Ahmed for executing it with the solution.

Well no one would have a problem hosting thier site with www.nozol.com

I am a reseller of Ahmeds as well and ahve a lot of clients hosted there and this really gives me added confidence in the ablity of Ahmed and of all you guys who pulled in and helped solve it.

Merry Cristmas and a prosperous New Year to you all
