Domain Name Server (DNS) Cache Problem? Or Server Problem?
Jun 26, 2008
I just migrate my server into IWeb, the server working great and in reasonable price but the problem is this server give me some funny problem. Anyone can help?
Basically I am in Singapore. My Website which suppose to show english content somehow become mass question mark as below. I am Sure that its not coding problem or Encoding problem since last time it can working fine (it happen only after I migrate the server from layeredtech into here)
But the content will show correctly if you open from US IP or other proxy server. I try in many computer here , some computer show error as I have. So its not computer problem as well since many computer see same error.
It will working fine again after I download and reupload the file but it will back again after 2 weeks.
Is it anything wrong with my server? or dns server setting? why only shown the problem from singapore-malaysia and indonesia side?
Some people say it because error on my DNS ISP , but I dont think so since many people in those country see the same thing. Any idea what should I do?
Upon reading http://www.theregister.co.uk/2008/08...sky_black_hat/ it appears those who use network address translation may be vulnerable to DNS cache poisoning even after patching their DNS servers.
"another 15 per cent are still vulnerable to some extent because they use network address translation gear that prevents the patch from working."
it took me one year to develop the disk cache tool which can dramatically boost your host and save your harddisk. it is like supercache,but more cheap and better speed.
check picture to see what it can do.
i will offer free download to test the tool by first 10 people. if u host huge traffic website, do not hesitate to try it. i already test it for half a year. it is time to publish it. pm me or post here to get free download.
This is the scenario, domain.com are setup on server1, however server2 also has the same profile of domain.com as we use ns3 and ns4 using domain.com. This works fine with the nameserver setup on server2.
However I encounter problems as the emails from server2 won't reach server1 as there are duplicate profile on server2.
My question is how do I setup the DNS in cpanel/whm from server2 so the emails from server2 will reach server1?
I use apache with CentOS VPS hosting for my blog. I only host one blog in this VPS account. I have 1.5GB RAM and I have 7, 500 page preview per day. My page loading time is 2-3 seconds (according to the pingdom tool).
I want to know what is the best performance (faster web page loading) W3 Total cache option for VPS hosting blog. Currently I use Disk to enhance for page cache and database cache for disk.
I have been searching everywhere trying to find a tutorial but It is not going anywhere. Basically I need to create 2 nameservers for Godaddy and pretty much so when i type http://mysite.com it goes to my site. I can access everything from http://myip and everything works. Now is there a step by step on how to actually do it in the DNS Manager? I need help like what IP address do I use is it the router ip? The external IP?
i am currently with a host, hosting my important sites. I am now going to purchase some space from another host purely for storage purposes and bandwidth usage as they are within my budget.
Now i have my primary domain with my main host, and i would like to have a script or link from my current host which leads onto my 2nd host for users to upload their images or files. Now i have a problem, the second host that i will have will not have a registered domain attached to it, but rather it will be just storage.
I would prefer to have a subdomain from my primary host pointing to my second host. The problem is where will the subdomain point to? Or will it even work that way without having to purchase another domain?
When I hit my server's domain it redirects me to one of the hosted sites' domain with a 302 redirect. It used to return the default plesk server page. How can I cancel the redirect?
I have 1 server so I setup dns as ns1.mydomain.com, ns2.mydomain.com ip address pointed to server1. So, now I just bought another server. Can I setup ns2.mydomain.com pointed to 2nd server. Also how to setup more servers ie. 10, 20 server because I can only set up to 6 dns in one domain name.
i had searching in this forum and in google How to set Subdomain to other server, i had try some of methode but still not working, because i cant set A Name in godaddy, because i use other webhosting outside godaddy
i just have ip address from my other server, i want subdomain to go this ip address, for example 10.42.1.21
what is your experience in godaddy, how to set Subdomain to other server, please give simple step by step dude
We have a lot of unused domains that we'd like to setup domain parking for.
To keep it simple, we'd like to just change the namesevers to ns1.domainparking.com and ns2.domainparking.com (not real nameservers!) and the domains would then automatically show a simple web page.
We use cpanel servers and are wondering how easy this is to do? I've seem mention of wildcard dns? Is that the answer?
i have about 8 different domains i'd like to point to a nameserver (ns1./ns2.mydomain.com) on Win2k3 server, but i can't get them resolved through my nameserver without creating a manual forward lookup entry for each *parked* domain separatly..
Does anyone know how to resolve "parked" domains automatically on Win2k3 DNS??
I just can't find any answer for this, everything i've found required manual creation of lookup entries..
But do i need to speak to the datacenter to add the reverse dns entries for my domain on their nameservers? What about if i host my nameservers offsite, but then have my webserver/mailserver etc inside the datacenter? Would i need to request the datacenter where the nameservers are hosted to add the reverse ip entries for the domain, and then the request the same from the datacenter for my web/mail servers to add the reverse entries?
I've been having some DNS problems with one of my domains for quite some time now. The domain does not always resolve - some go days without being able to access the site.
I ran a simple BASH script to show what I mean. I replaced my domain with "mysite.net" and the IP with "xx.xx.xxx.xxx".
# for i in `seq 1 15`; do host mysite.net; done
mysite.net has address xx.xx.xxx.xxx mysite.net mail is handled by 0 mysite.net. Host mysite.net not found: 2(SERVFAIL) mysite.net has address xx.xx.xxx.xxx Host mysite.net not found: 2(SERVFAIL) mysite.net has address xx.xx.xxx.xxx Host mysite.net not found: 2(SERVFAIL) mysite.net has address xx.xx.xxx.xxx Host mysite.net not found: 2(SERVFAIL) mysite.net mail is handled by 0 mysite.net. mysite.net has address xx.xx.xxx.xxx Host mysite.net not found: 2(SERVFAIL) Host mysite.net not found: 2(SERVFAIL) mysite.net has address xx.xx.xxx.xxx Host mysite.net not found: 2(SERVFAIL) mysite.net mail is handled by 0 mysite.net. mysite.net has address xx.xx.xxx.xxx mysite.net mail is handled by 0 mysite.net. mysite.net has address xx.xx.xxx.xxx mysite.net mail is handled by 0 mysite.net. mysite.net has address xx.xx.xxx.xxx mysite.net mail is handled by 0 mysite.net. mysite.net has address xx.xx.xxx.xxx Host mysite.net not found: 2(SERVFAIL) mysite.net has address xx.xx.xxx.xxx mysite.net mail is handled by 0 mysite.net. mysite.net has address xx.xx.xxx.xxx mysite.net mail is handled by 0 mysite.net. mysite.net has address xx.xx.xxx.xxx mysite.net mail is handled by 0 mysite.net. mysite.net has address xx.xx.xxx.xxx mysite.net mail is handled by 0 mysite.net.
Has anyone experienced a similar problem? I have gone over the DNS records countless times and see no problems. The site is hosted on my own dedicated server.
I got Problem with DNS , Some time it's work the sites on the server some time it's not
The report From DNS:
ns116.***********.: Parent server (k.gtld-servers.net) says A record is 72.232.232.133, but authoritative DNS server (72.232.232.132) says it is 72.232.232.131
ns115.***********.: Parent server (k.gtld-servers.net) says A record is 72.232.232.132, but authoritative DNS server (72.232.232.132) says it is 72.232.232.130

I am fairly sure this is impossible, but I figured I'd ask anyway.....
Right now I have a forum setup at http://support.myhostingcompanydomain.com/forum/ and I would like to move the forum to another server on another network, so I'm wondering if its possible to have
http://support.myhostingcompanydomain.com hosted on one server and
http://support.myhostingcompanydomain.com/forum/ hosted on another?
I currently have two VPS servers, each with 2 DNS names running on them as follows:
dns1.mydomain.com (on Server A) dns2.mydomain.com (on Server A) dns3.mydomain.com (on Server B) dns4.mydomain.com (on Server B)
I have websites running on each server and I would like to have something set-up so that when one server goes down, the other server displays a nice page saying the website is unavailable currently and will be back shortly - you know, something nicer then the normal "Server Not Found" default messages.
What is the best way to do this?
If I have CLIENTDOMAIN.COM and put them on Server A and they use all 4 DNS server names, will the top two DNS names always be used by people finding the website, and the bottom two choices only be used if the top two can't be found?
I believe I have to create an account on Server B for them as well, just only placing the temporary page within the account, rather then a whole copy of their website. Correct?
I´ve a domain but haven´t set the DNS servers yet....now I get a free hosting and I wanted to associate the DNS servers to my domain but I don´t know how!!!
It would be great If you could help me...and let me know if you need more info..
I currently have a domain on Server 1 (Linux, Apache, Ubuntu, Matrix control panel).
This server does not have any spam filter, so I have moved all the email accounts to Server 2 (Linux, Apache, Fedora Core, Plesk) which does have a brilliant spam filter; and have changed the DNS record for mail.domain.com to the IP address for Server 2.
Emails are being successfully received on Server 2.
On Server 1, when an email is sent through SMTP to an address at that domain, it does not send it to Server 2, it gets delivered to the hosting account for the domain on Server 1. So what I am guessing is happening is that Server 1 detects the domain has an account on the server, and instead of looking up the DNS info for that domain, just assumes it is on Server 1.
What I need to do, is force Server 1 to send email for that domain to Server 2. Is this possible, and if so, how can it be achieved? If more info about the server is required for a solution please let me know and I'll provide what I can.
Im trying to get my hosting going but i relised i need a name server for domains. I have no idea how to do any of this. What i want is to be abel to point name server to my server and then direct where it should go. Im running windows 2003 server on it.
I'm going to start to configurate a VPS and I have a few questions, please help me.
1- If I have a VPS and I want to have some domains there, Do I need private nameservers? Is there any other way to go? (for example, could I use the DNS of my provider?)
2- How many IP Addresses do I need for a VPS? I think if I have to use private nameservers I'd need two IP for them. Is it correct?
And if I want to have reverse DNS for my Host, I think I would need a IP address to be used on for that. Is it correct?
So, I would need at least 3 IP Addresses. Is it correct?
3- Is it possible to use a VPS with only two IP Address? Many VPS providers give you only two IP Addresses. Could I use 1 IP Address for DNS and reverse DNS for my Host at the same time?
Is it not a problem with hotmail, yahoo, gmail, etc?
I'm totally new at the dedicated server thing. I want to point a domain (mintylabs.com) to my server IP making it possible to have my own custom dns (e.g. ns1.mintylabs.com).
