How to configure a secondary nameserver/webserver

We've been trying to get a back-up nameserver+webserver up for a while now. Also been trying to test it but no luck so far. We're definately no experts in this area so therefor my question here.

We have set up both servers with nameservers and a records like this:

ns1.domain.com   A    123.456.7.89
ns2.domain.com   A    123.456.7.89
ns3.domain.com   A    987.654.3.21
123.456.7.89        NS   ns1.domain.com
123.456.7.89        NS   ns2.domain.com
987.654.3.21        NS   ns3.domain.com

Both servers have the same domain setup with these values in plesk. The ns3 has de ip address of the back-up server and ns1+ns2 have the ip address of the original server. At our nameserver provider we have added the 3 nameservers.

We've been trying to test when we take down our dns+apache service at out original service. We were hoping that when we entered the domain name it would go to the back-up server but instead we just get a browser error.

What are we doing wrong?

Hi yah,

when you  do Dns check of your domain, what result do you get ??
http://www.checkdns.net/quickcheck.aspx or use any dns check web site

does it say that you have 2nd name server ??  is this live or it shows 2nd name server is not found

when you have registered your doamin , did you defined that you have 2 namesever ??

and another thing is:
123.456.7.89        NS   ns1.domain.com
123.456.7.89        NS   ns2.domain.com

why Ip is same !!??

it should be

ns1.domain.com   A    123.456.7.89
ns2.domain.com   A    123.456.7.90
ns3.domain.com   A    987.654.3.21
123.456.7.89        NS   ns1.domain.com
123.456.7.90        NS   ns2.domain.com
987.654.3.21        NS   ns3.domain.com

Last thing - > when you Registered the domain,

is there any options of putting : 3 nameserver ??

normally, i saw , every domain registration company gave 2 nameserver options

if you get 2 nameserver options -> then you must of typed ns1 and ns2, but where is your ns3 ??



but if you got 3 nameserver options, then  i will advise to check record with Dns checker
then i can sent you some good tested tutorial for setting up secondary nameserver

You are right about the IP numbers, what you said it should be. We got 2 nameservers when we registered the domain which are ns1+ns2 and they have a seperate IP. We later got the ns3 nameserver which we're trying to add now. I checked with the dns checker from the url.

The checkers finds all 3 nameservers. When checking if they are alive all 3 get errors. The first 2 get the error "DNS server ns1.mydomain.com[ip-address] is alive, but not authoritative for domain 'www.mydomain.com' and didn't return SOA". This very likely is a result of us testing to get it to work. We are not sure how to set up the third nameserver in plesk. The ns1+ns2 server are used for 2 domains at this moment because we are testing the nameservers on a seperate domain then the one we will be using it for. The third namserver returns the error "Error fetching SOA from ns3.mydomain.com[ip-address], server returned non-SOA record, type 5".

ns1+ns2 are on server1, ns3 is on server2. Both servers are nameserver+webserver. Server2 should kick in when server1 is down.

And also last thing is : what did you WRite on you SOA Record in  ns1 nameserver setup ??
can you check you name.conf file ??
cd /etc
vi named.conf

check if the entry is something like this :
zone "somefakedomain.com" IN {
      type master;
      file "somefakedomain.com.zone";
      allow-update { none; };
};

then : Switch to named folder :  cd /var/named
cp localhost.zone somefakedomain.com.zone
vi somefakedomain.com.zone

did you write something like this ??


$TTL 86400
$ORIGIN somefakedomain.com.
@      IN      SOA      ns1.somefakedomain.com. admin.somefakedomain.com. (
                  2004042601      ; serial

Yes both servers are basicly copies from eachother, both webserver and nameserver for the same domain. At first we saw the files that were on server1, now we are seeing them on server2. What we want is that it should get the webpage from server1 unless the ns1+ns2 are down then the browser needs to go via ns3 to server2 and get the webpage from there.

We want server 2 to have a copy of the files and a different nameserver so if server1 sometime completely crashes we have a fully ready back-up server.

Gonna check for the SOA file now, haven't checked it before and can't see it in plesk. I have ssh access so I can check through there.

yes, check the SOa record , its Dns issue.

But only problme is bugging me : What i have done , my ns1.domain is one server1
ns2.domain is server2
and  ns2.domain is server 3

so here : if server1 is primary server and Server2+ Server3 is Slave nameserver ( who copy Record from Server1)

so if Server1 is down Server2 or Server 3 will take control

But in your case : you put  Slave nameserver(ns2) with primary server(ns1).
what the point of ns2 ? if Server1 goes down !!!! is not it ??

if Server1 goes down , then ns2 is useless , so actually, you are using ns2 unnecessary!! is not it ??


anyway, its your setup.

and also : are you copying Web site content from Server1 to server 2 manualy  ?? becuse you wil have to make sure that when Server1 goes down, Server 2 has the same content.


Last thing : if you use this setup :

ns1.domain.com   A    123.456.7.89
ns2.domain.com   A    123.456.7.90
ns3.domain.com   A    987.654.3.21

then, ns2 will not work, because you put ns2 in server1, and server 1 can handle only 1 IP,
is not it ??

anyway, check the Soa record, let me know whats in there, because your problem is in SOA( dns setup)


You didnot answer me my last question :

with 2 server up and runnning, if you try to browse, can you see your web page ???

if the answer is Not then
 ,  if you shutdown your Server 2, can you see your web page ??

If we browse to the webpage now we see the web page yes.

ns1+ns2 are on the same server so I guess you could call ns2 a bit useles yes but it shouldn't be a problem either? The content files are copied periodicly by a script so they will be a bit outdated but fairly the same.

I found the name.conf and it says this at the domain:
zone "mydomain.com" {
        type master;
        file "mydomain.com";
        allow-transfer {
                12.345.678.90;
                12.345.678.91;
                common-allow-transfer;
        };
};

however this "cp localhost.zone somefakedomain.com.zone" does not work, also not in the directory you mentioned. It says localhost.zone is no file or directory.

But I think the SOA file is also adjusted by what we enter in Plesk? Could you maybe give an explenation on how you would setup the domains in plesk? We're unsure on how and on which server we should enter the nameserver A and NS records, on both? on only 1?

ok here you have checked only named.conf  which is saying : ns1 is primary  nameserver and SOa record will be transer to ns2 and ns3.

now you will have check SOA record in ns1. because SOA reocrd is the main for maintaining A, MX and other nameserver and this SOa record would be transfer to ns2 and ns3 automatialy.

to check this you will have to see what inside mydomain.com.zone
check this command : locate mydomain.com.zone
its should show where is your mydomain.com zone file
to see what inside , cat mydomain.come.zone

or it could be located : cd /var/named/chroot/var/named


the theory is : in primary Dns server : you will have SOA record in zone file .
and this SOA record would be copied to Secondary and third nameserver automatically.

since your ns2 is useless, so in Third nameserver ( server2), its named.conf  

you will have to type this :
zone "somefakedomain.com" IN {
      type slave;
      file "somefakedomain.com.zone";
      masters { 192.168.1.200; };
};

here master is your ns1 ip address.

if you want just check this web site : http://fosiul.co.uk/showknowledgecategory.aspx

first link is to configure primary nameserver and link 2 is secondary  name server
in your case secondary nameserver would be your server 2(ns3)

so, you will have SOA record in primary nameserver (ns1) in "mydomain.com.zone"

and this SOA record would be copied automatiacally to ns2 and ns3 ( in your case ns3) because it will not find ns2.


and these  your zone file for mydomain.com.zone would be located in ns2 under Slave folder in named   folder

it would be it : cd /var/named
or cd /var/named/chroot/var/named/slaves

here Slaves file would be created automatically. you dont need to do anything . you will just have to edit  your named.conf in ns3 as i said my last post

ohh about this command : cp localhost.zone somefakedomain.com.zone

what it will do is : it will copy localhost.zone as somefkedomain.com.zone

because you need to create zone file for your domain mydomain.com . Because localhost.zone file is already there, so i said, to copy localhost.zone file and past it as mydomain.com.zone file
so it would be cp localhost.zone mydomain.com.zone

then Edit mydomain.com.zone  file for Editing SOA recorod

Since you can see your web site, that mean, you have mydomain.com.zone file already there.

you will just have to check if there is any SOa record in there or not. its the main thing


so do it one by one :

first check : Server1 zone file.
then go to server2 zone file ( which would be in Slave folder and also you need to edit named.conf)

do it one by one.

and tell me what you have done so far

I am trying it now, I have located the SOA file on server1 which has the same data as plesk has, it contains the same information. ns1 and ns2 are in there in the same way we discussed earlier.

I have also found the named.conf file on server2, but it also says master. Both server have the same thing. Both say it is 'type master' and both have their own IP addresses at the allow-transfer IP's. Still not completely sure on things your explaining, I can just change the server2 file and make a 'type slave' of it and add a master IP?

Gonna check out your link now.

ok here is problem : in server2 named.conf it should say Slave, ( NOT MASTER, BECAUSE MASTER IS NS1)

in named.conf ( ns3) you will have to type :
zone "mydomain.com" IN {
      type slave;
      file "mydomain.com.zone";
      masters { 123.456.7.89; };
};

this Ip :123.456.7.89 is your Server 1 ip (TYPE ns1 ip, NOT NS2 IP(because it will not find IP of ns2)
So it will copy SOA record from ns1 to ns3( under Slave folder)

This is what it says now after trying a lot of things again. I'm not really getting it. I followed the guide and insert A records for the nameservers, 2 for server 1 and 1 for server 2 but they got overwritten again.

Not sure if it's wise to keep trying to get it to work, we're looking if we could maybe let someone else fix it or maybe look for a DNS hosting company, not many of those in the netherlands as far as I know.

you need to tell me something
ok is tuxx1234.nl  your Original domain ??, then your Dns setup is 89% fine.
i have just checked, its saying :

NS list mismatch: registration authority reports that domain is hosted on the following servers: 'ns1.ns-tuxx.nl; ns2.ns-tuxx.nl', but DNS server ns1.ns-tuxx.nl reports domain to be hosted on 'ns3.ns-tuxx.nl; ns1.ns-tuxx.nl; ns2.ns-tuxx.nl'. Please make sure that you configure the same DNS servers in registrar database and on your DNS


According to this : its saying :( and also i said to you my very first post) your domain registration is saying : you have 2 name server which is ns1.ns-tuxx.nl; ns2.ns-tuxx.nl.

but in your dns setup you put Extra Dns Server which is  ns3.ns-tuxx.nl ( WHICH WILL NOT WORK) ( if you want 3rd nameserver to work, you will have to mention it in domain nameserver configuration)

tell me if you got it or not ?? ( THIS IS YOUR FIRST PROBLEM)

its easy to setup Dns .

here, In domain configuration, if you say you have 2 nameserver, you will have to work with 2 nameserver ( which is fine  )

but in your domain configuration, you said you have 2 nameserver, but in your DNS setup you are saying,you have 3rd NameServer which will not work.

From Dns check this what i got:( i have edited domain name and IP)

DNS server ns1.xxxx.nl[87.xx.xx.88] is alive and authoritative for domain xxxx1234.nl
  DNS server ns2.xxxx.nl[87.xx.xx.89] is alive and authoritative for domain xxxx1234.nl


Now if you want another nameserver to work , you need another IP and You will have to tell this in your domain configuration that i got 3rd nameserver. and  when you will do dnscheck you will see this line has been added

DNS server ns3.xxxx.nl[87.xx.xx.90] is alive and authoritative for domain xxxx1234.nl

 other wise, if your First server goes down, 2nd server will not take control.

i will be offline for 1 hr,
let me know what happeded

The third nameserver is added in the nameserver domain registration. Server 1 has the first 2 IP's of the ns1+ns2 and the new server has the IP for ns3.

The biggest problem is how do I insert this in plesk. I need to know which NS and/or A records I need to insert for each domain to make it work as a whole. I have been experimenting with several combonations of NS and/or A records because I don't know which needs to be where.

In about 1 hour and a half I need to go and can't test anymore for 6 days, but then I will continue to look for a solution. Thank you for all your help already, I at least understand things a little bit better then before :)

About your this comment : The third nameserver is added in the nameserver domain registration

when did you Added ?? within 48 hours or Before ??


About yoru this comments :
NS and/or A records because I don't know which needs to be where.

I dont know how pleask work, but i am sure its same as how we setup linux from command prompt

Basicaly : You will put everyinformation at Server1. the information you provided its fine.


EXCEPT : here i am not seeing any A Record for Server2 .

so you will have to Add A record for server2 In Server 1 which would be like this :

$TTL    86400

@       IN      SOA     ns1.mydomain.com myemail.com. (
                        1213172167      ; Serial
                        10800   ; Refresh
                        3600    ; Retry
                        604800  ; Expire
                        86400 ) ; Minimum

mydomain.com.             IN NS   ns1.mydomain.com.
mydomain.com.             IN NS   ns2.mydomain.com.
mydomain.com.             IN NS   ns3.mydomain.com.
mydomain.com.             IN A    87.233.131.88
mydomain.com.             IN A    87.233.131.90
mail.mydomain.com.                IN A    87.233.131.88
ftp.mydomain.com.                 IN CNAME        tuxx1234.nl.
www.mydomain.com.                 IN CNAME        tuxx1234.nl.
mydomain.com.             IN MX  10 mail.tuxx1234.nl.

Here : Ip 87.233.131.90 is the public Ip for 3rd nameserver.



Now Come to 3rd nameserver : in named.conf file, you wil have to make it Slave. you dont need to do anything.
zone "mydomain.com" IN {
      type slave;
      file "mydomain.com.zone";
      masters { 87.233.131.88; };
};

The way you have created 2nd nameserve by plesk, just create same way 3rd nameserver.

or if your pleask does not give you options to do this , then you will have to do this manually.



*** why so much hardwork, you can put ns2 in seperate Server thats all, when ns1 will be offline ns2 will take control. ( this is what you wanted is not it ??)

I don't know the exact plesk version but plesk is exactly the same as the SOA file. I think I have got em working now, but tuxx1234.nl still shows the webpage which is on the back-up server. I'm not sure about the delay with DNS stuff but the tests seem to say all the dns servers are working. Maybe I still need to make the back-up nameserver the slave, going to look somewhat further. Are your tests also giving good results on the domain?

Hello, back again. DNS servers seem to be working correctly but the webpage is now coming from server2 and because server1 is up that shouldn't happen. It should come from server1. Can you tell what you use to check DNS from a website? Might be useful for us here.

Hi
its http://www.checkdns.net/

yes your Web site is comming from Backup Server .

Check the A Record, if your A Record points to Backup server, then your site will come from backup Server

if your A record points to Server1 , your web site will come from Server 1

I was thnking , you will do that!!

so you Wrote some thinng like this  , is not it :

A XX.233.131.XX
A XX.239.210.XX

it will not work, you will have only one A record

After you delete your A record of Backup server if you check your Dns report, you will see your Web page is running from
Server1 which is XX.233.131.XX. Which is right.

Now problem is : Since your webserver is Server1 . now if Server1 is down . Backup Server will take control but WEb page will not come because Web page actually in server1 which is down.!!!!
do you understand ??

You have solved your problem of Secondary Nameserver but not web server.
how to solve problme of backup webserver its another topics!!

Server2 is a nameserver and a webserver. So when server1 is down server2 should take over as webserver and nameserver.

When I check the domain now, www.tuxx1234.nl still shows the back-up server webpage. tuxx1234.nl (without the www) shows the website from server1 I think.

tuxx1234.nl shows neither the page on server1 or server2. It only works with www in front of it. Without the www it shows an older version, not sure where he gets it from.

If I check with http://www.zonecheck.fr/ it says the primary nameserver is ns1 which goes to the server1 ip address.

Ok this is new i have learnt today!!!

When I am checking your Dns report , its saying : DNS round-robing with multiple web servers detected !!!!!

What round robin does it, its toggle from one Server to another server. Suppose , if you go to your webserver first time, it will come from Server1 then if you click on one page it will come from Backup Server and vie versa.
So every time, i am doing Dns check, its giving different Webserver address.

check with this one : http://www.squish.net/dnscheck/dnscheck.cgi
its giving your full Zone report.

Now i want to check something :
First shutdown your Server1,
and let me know
then i will do some Dnscheck
then i will email you back

then again shutdown your backup server, then i will do dns check
then i will come email you back

ok ??

let me know when you have shutdown your Server1

Server1 can't really be down for a long time or my boss will not like me anymore :p it also hosts the real website. It seems like the DNS servers are chosen randomly, cause when I check www.tuxx1234.nl I always get the 'blabla' at the topleft which means it's the back-up server files.

yes, its commign randomly,
i am not too much confident with putting A record for all server. because if you use Database , then it could be problem for Viewing webites

by the way, is there any problem with your website ??
Some times its showing: parallels control panel and some time page is comming but withotu Any CSS or graphics

Ok check this another site, which give a nice explanation of Dns record :
http://www.intodns.com/tuxx1234.nl

if you check WWW seciton :
the order is giving is this : Your www.tuxx1234.nl A record is:
www.tuxx1234.nl -> tuxx1234.nl -> [ 193.239.210.188  87.233.131.88  87.233.131.89  ]


Because if you check your ns1 zone , you put Backup server A record first

33.3% of queries will be returned by 87.233.131.88 (ns1.ns-tuxx.nl)
      

tuxx1234.nl.      86400      IN      A      193.239.210.XX
tuxx1234.nl.      86400      IN      A      87.233.131.8X
tuxx1234.nl.      86400      IN      A      87.233.131.X9

and also you does not have glue record for Backup Server
ns3.ns-tuxx.nl.   ['193.239.210.188'] (NO GLUE)   [TTL=7200]

Did you enable round robin ??
Because i did not  see this round robin when we started this topics first time but today i am seeting this round robin.

every time i checked your WWW record by http://www.intodns.com/tuxx1234.nl, its changes!!

when i click ones to check it showed me :

the order is giving is this : Your www.tuxx1234.nl A record is:
www.tuxx1234.nl -> tuxx1234.nl -> [ 193.239.210.188  87.233.131.88  87.233.131.89  ]

when checked again :

Your www.tuxx1234.nl A record is:
www.tuxx1234.nl -> tuxx1234.nl -> [ 87.233.131.88  87.233.131.89  193.239.210.188  ]

so it changing WWW Record and Dns Reocrd  by itself, it should not be any problem if you have just Static website.
but if you have any database related website, Trust me it would be a pain

anyway, you website looks like messy.

What is a GLUE record? I have no idea how I put in my back-up server A record first, I don't know where I can change that.

It also gives an error about recursive queries.

"I could use the nameservers listed below to performe recursive queries. It may be that I am wrong but the chances of that are low. You should not have nameservers that allow recursive queries as this will allow almost anyone to use your nameservers and can cause problems. Problem record(s) are:
87.233.131.89
87.233.131.88"

I'm not sure how to solve this either.

About round Robin , i meant, did you enable round robin by itself or Its been enable from before ??

Here : Round robin is enabled already.

Because when i checked your Dns record First time, then i dont think round robin was enable, but today i can see round robin is enable.

anyway, its does not any matter if its enable, i think your Pleask software enable this one automatically.

What is a GLUE record?  ==  You will have to create a Glue record for your doamin Registration control panel, you already did for Nameserver1 and nameserver2 but you did not create for nameserver3.( as I told you before my first post)

like the way you define for nameserver1 and nameserver2 from your domain Control panle( its not your Server , its from where you have registered your doamin)you wil have to define that i am using nameserver 3 which is : ns3.ns-tuxx.nl and its Ip is 193.239.210.XX  ( if there is any options to create glue record for 3rd nameserver from your domain control panel)

about recursive queries :I guess,  its because you put both nameserver in one Server!!! (  i will never do that)



conclusion : the way its now been setup, i think your problem willl be solved.

because, webpages is comming from different server, so if one is down it should come from another

let me know if any problem....

Trying now to throw out ns2 completely but there is some delay untill the master dns servers will know I think. I think you gave as much answers as you can, gonna try some more this afternoon and if I have questions I'll post again.

Round robin was indeed auto activated. I think it is now deactivated because there is no ns2 anymore, gonna take a break now and hopefully afterwards the master servers will be updated.

if you take my advise, if you are unable to create glue record for     nameserver 3 then Dont through ns2. instead through nameserver3. then put ns2 in Backup server

so your glue record will be fixed then.

Read bellow carefully :

You didnot have  to deactivate Roundrobin , i think it is working fine.
 if You deactivate round robin, then I think, you will not be able to use more then one A Rerod at same time!!! you will have to use only one A record at a time. either A record for ns1 or A reocrd for ns2 Or A reocrd for ns3

I belive, Since your round robin enable, thats why , its taking A record from all Server at the same time( which is good but only problme you might face for Database related website)

Read the above comments carefully.

if you dont use Database SErver, then you can keep your round robin enable.

let me know if you have any question , some time i just type so it might not make 100% sense due to lack of explanation, so asked me if you have any question of my explanation
