Hello,

I'm rather new at this but I have a dedicated server with 4 IP addresses and my host has 2 nameservers which I can use. At my registrar I entered these 2 nameservers and at my host I also entered this information plus the IP address to my box to update their nameserver, I assume. So far it's all OK and has been working fine for over a year but now their nameservers have been causing problems, a lot of my users cannot access my domain anymore because of DNS errors.

http://www.dnsreport.com couldn't even find the nameservers of my host so I'm wondering what is the best step for me to do in this case? I don't have to worry about other domains since I'm not reselling. Should I run a DNS on my linux (redhat 9 w/ plesk) box and use this as Primary DNS? And if so, how do I do this? I have no clue icon_wink.gif

well I dont use plesk, but I'm sure it has a control panel to run dns servers, more importantly though is setting up the new nameservers at your registrar.

you have to create nameserver "glue" records, under the domain that these new nameservers will exist.

then setting up plesk should be pretty straight forward, you'll also want to enter reverse ip records at EV1 for your nameserver IPs

Sorry, I'm very new to this I don't understand everything you just said.

This are my current Plesk settings which I enter with the help of this forum:
QUOTE
DNS zone enabled.
DNS zone has master DNS server type.  

mydomain. com.   NS   ns. mydomain. com.    
mydomain. com.   NS   ns1. mydomain. com.    
mydomain. com.   NS   ns2. mydomain. com.    
ns. mydomain. com.   A   69. xx. xx. x3    
mydomain. com.   A   69. xx. xx. x3    
webmail. mydomain. com.   A   69. xx. xx. x3    
mail. mydomain. com.   A   69. xx. xx. x3    
ns1. mydomain. com.   A   69. xx. xx. x4    
ns2. mydomain. com.   A   69. xx. xx. x5    
ftp. mydomain. com.   CNAME   mydomain. com.    
www. mydomain. com.   CNAME   mydomain. com.    
mydomain. com.   MX 10    mail. mydomain. com.    
69. xx. xx. 43/24   PTR   mydomain. com.

Is "ns. mydomain. com. A 69. xx. xx. x3" needed?

This is what I entered at my registrar:
QUOTE
Name servers:
NS1.MYDOMAIN.COM  
NS2.MYDOMAIN.COM

DNS hosts:
ns1.mydomain.com -> 69.xx.xx.x4
ns2.mydomain.com -> 69.xx.xx.x5


Since I use my own DNS servers, should I insert the data on the website of the company hosting my dedicated server? Currently it's using the following, which I used when using their nameserver:
QUOTE
Name Server:
ns1.theirnameserver.com    
ns2.theirnameserver.com    
 
Main address:
69.xx.xx.x3  
 
Mail Server     100 mail.mydomain.com    

Subdomains:
www A 69.xx.xx.x3    
mail A 69.xx.xx.x3    
ftp A 69.xx.xx.x3    
* A 69.xx.xx.x3    
ns.erollisimarr.com A 69.xx.xx.x3


Also, should I use the Reverse DNS option? It's currently not filled in but I assume that if I have to use this that it should be used this way:
69.xx.xx.x4 -> ns1.mydomain.com
69.xx.xx.x5 -> ns2.mydomain.com


I've tested my website with DNSReport.com and it gives the following errors:
QUOTE
ERROR: One or more of the nameservers listed at the parent servers are not listed as NS records at your nameservers.

Warning: Your NS records at your authoritative DNS servers have TTLs that do not match what the parent servers report:

Your DNS servers leak stealth information in non-NS requests:
Stealth nameservers are leaked [ns.mydomain.com.]!


SOA REFRESH and SOA EXPIRE are always warned for their values being too high but I don't know if it's referring to my DNS or my host's.

Multiple MX records, Mail server host name in greeting, Acceptance of domain literals are also marked as WARN.

Thanks for any help icon_smile.gif

Anyone?

Or,
use a free service such as zoneedit.com.

I was using two free DNS servers that's what started this all icon_wink.gif

Zoke: ugg, following your post makes this more confusing then it needs to be, contact me on AIM (LogicalDope) if you want to talk live, and we can straighten this out. I'm going to lunch right now, so if you read this like 2 mins after I post it, give me 30 minutes icon_smile.gif
Zoke
I don't have AIM, or any other instant messenger. I was hoping that it wasn't confusing by using all the quotes but to me it all is icon_wink.gif If there's something specific you're confused about, I'll try to give more information.
css145hs
well, if you provide your domain name, then I can easily check to see if its all setup correctly at your registrar and in your nameservers.

Also the ips of the nameservers you want to use (in the case where its not what your domain is setup for).

You can pvt the info, or put it in form, its really not anything private. However if your not comfortable with giving the domain name out, then we can go through a question/answer routine.

*edit* need to learn how to speel forum
*edit again* need to learn how to spell spell, jeez not looking good today icon_smile.gif

ok, you need to remove ns.yourdomain.com from your cpanel/whm configuration. OR add it to your domain registration records. (these two are supposed to match)

Other then that your setup is fine.

At your registrar, (and you may not be given the option), you should specify that your domain will be/have nameservers, and what they are, in addition to specifying the nameservers for your domain. The cheaper registration services do not offer this, although EV1 does icon_smile.gif. without it things will likely still work, but later changing things becomes much more difficult. By specifically stating that your domain will be a nameserver, your IPs get put in the root server, rather then having to do recurisve lookups.
Zoke
Thanks a lot icon_smile.gif

I'll remove ns.mydomain.com in Plesk.

At my registrar I entered this info, as quoted above:
QUOTE
Name servers:
NS1.MYDOMAIN.COM  
NS2.MYDOMAIN.COM

DNS hosts:
ns1.mydomain.com -> 69.xx.xx.x4
ns2.mydomain.com -> 69.xx.xx.x5

I could add up to 9 IPs per DNS host I believe, so I have no idea if I did this correct.
Zoke
If anyone else knows the answer to this I'll be just as happy icon_wink.gif
Zoke
Still hoping for a little help here *bump* icon_wink.gif

you have to wait, dns information, registrar records are all cached at various places

plus, removing that one entry, doesn't make dns report say its good, cause you still have extra nameservers in your domain registration, it wont be until you remove them that it reports its fine

your new nameservers do resolve the domain, I queried them specifically with dig, so they are setup, so switch to them, and you'll be fine, then wait two days and check dnsreport
Zoke
OK, cool. I'll remove the ns.mydomain.com from plesk and i'll remove the two other DNS servers of my host too. How did you test my nameservers, so you know they'll work alright when I remove the other two?
css145hs
yes they will work, I tested it by manually querying your nameservers, rather then quering through the dns cache that my system is configured to use.

on windows you can use nslookup, on nix use dig

I also checked the whois information, to make sure they would refer to your domain. your ready to go, just delete the misc/old configuration from both plesk and your registrar.

on a side note, the days you spent on this issue could have been mitigated by reading some dns tutorials/guides. icon_smile.gif
