View 7 RepliesMy configuration: CentOS in a VPS environment, I have 2 static IPs at my disposal.I'm having trouble setting up my nameservers. I've registered the nameservers with my registrar and supplied the GLUE records, however my registrar has not yet applied this information into the DNS zone, because my nameservers fail to generate a response on port 53.DNS check says the following about my nameserver address:Checking SOA records for domain. Domain server is not answering to UDP requests on port 53. Possible problems: A firewall is blocking port 53, server is down, server is not running software for handling dns requests.So the only two possibilities I see is that my port 53 is somehow blocked or not properly set to accept and send the correct traffic or that I've misconfigured BIND.

Like I have a master nameserver, a slave nameserver and a caching nameserver in my network. Is it possible to know that which of these servers replied my dns query? Also can i trace back that replying server exactly?

I'm thinking I could add the below to the options stanza in the /etc/named.conf file:
recently we decided to make our own panel (like Plesk or cPanel) but for Ubuntu and it will be licenced under GPL (like any other professional sofware).want to make a panel not only that fits our needs but also the needs of other system administrators and domain owners. We researched other panels and found out that non of them has security/look/ease of use in one package. Bad codig is another problem found in other panels.I made a short overwiev of what I think we have to have in the beginning.I Security :1. Completely chroot enviornoment where every single service is in chroot mode (bind,mysql, postfix, .... )2. Easily managed IPtables trough web-based interface. 3. Coding rules has to be strict.

I have been a BSD guy for years, but I am now shifting over to CentOS for my first server build.
So far so good, all has been relatively painless and in fact a heck of a lot simpler than I anticipated!
Everything seems to have gone ok except a small problem with Bind. At some point during setup, I accidentally ran "yum remove bind-chroot".
When I tried to run "yum install bind-chroot" I got told "No package bind-chroot available" which was odd.
Anyway, I managed to find the rpm for bind-chroot and installed it that way. Now I see that there is a bind update available
Unfortunately the rpm I installed now has a dependency for the current version of bind which I can see being a headache everytime bind needs updating.
So, can anyone help me get back bind-chroot the proper way? code...
I just tried to upgrade my server to the latest version of Bind9 and the process fails gets frozen.First note that I have Bind in a chroot jail.When I try the upgrade, or the recommended "dpkg --configure -a", it displays this then hangs:Quote:
Setting up bind9 (1:9.7.0.dfsg.P1-1ubuntu0.1) ...
* Stopping domain name service... bind9 rndc: connection to remote host closed
[code]....
I am configuring bind9 on fedora 9(sulphur).I have configured /etc/named.conf and created zone file in /var/named/I have started the service but when I am executing the command nslookup mydomain.com it is not able to resolve the name.Another problem I am facing when I do telnet localhost 53,I am able to connect.but when I do telnet myip 53 it does not connect.Seems to be a firewall problem but I ve disabled iptables selinux completely even I ve disabled dnsmasq but still not working.

View 2 Replies View RelatedI have read a lot of documentation but it is still hard to find a proper answer to my doubts.About the hostnames in a domain, how is it associate to a determinated port?
For example, when I type on the browser webmail.sparc86.net and then I get redirected to the port of 20000 of this same domain. Fine, but how does it work that it knows it should be redirected to the port 20000? From where is this information (the association webmail-port 20000) taken? The apache will manage this, right? But what about other services like ftp?Another example, If I wrote my own software listening, let's say on the port 40000 and I want to have a domain like "mystuff.sparc86.net" how would I let it be redirected to the port 40000 ?
Currently i using webmin,but it missing some important things like $variable -where $variable would be automatically replaced with added domain,and it's kind a strange since plugin for managing other dns server on webmin does that. Also i was not able to generate 100% correct all records,only partial,which make it useless since i was need to fully replace it anyway.So can someone recommend any script/tools for it?I would be even happy with combination of batch tools(which might be even best solution since then i would not need to bother with installing script). How my dns records look:
PHP Code:
$ttl 38400
@ IN SOA ns1.nameserver.com. root.localhost. (
12520521667
7200
7200

i am trying to run bind in centos 6 and bind keeps giving me errors every time i check all of the configurations. the named.conf file works fine but the zone files keep giving me errors heres the contents of my named.conf file

I am currently running the latest version of Bind, and for some completely unknown reason I can NOT get queries to work for PTR records. All queries to the servers for reverse name lookup get query denied:
Using domain server:
Name: 66.150.173.1
Address: 66.150.173.1#53
Aliases:
Host 27.173.150.66.in-addr.arpa not found: 5(REFUSED)
And it shows in my logs:
I am at my wits ends with the piece of crap. Can anyone shine some light on why this damn Bind install won't respond to these queries?
For reference here is my named.conf:
Code:
I am working one project and i want to know that is it possible to find out the DNS (BIND) QPS (query per second). I mean how many QPS BIND can handle.

I've got an interesting problem when it comes to wildcard entries in bind. If I put the following in:
qa.express IN A 172.16.0.10
* IN A 172.17.1.156
If I then look up "express.example.com" it doesn't return an answer - it *should* return 172.17.1.156, but it won't unless I put that hostname in specifically. qa.express.example.com resolves as expected.
I just download OpenSUSE 11.2 x86-64 distro. I installed it. No problem.
I run bind but i cannot start named. Other server services were running well.(dhcp, squid, apache2....)
I cannot start bind only.
I am setting up a new infrastructure which led me to install BIND in a non active directory (new) environment.
With that stated I don't have any .com nor any domain setup so im unable to dig my network domain; Im only operating via workgroup.
Is it still possible to setup BIND dns even though I dont have a domain (i.e. csaa.com, csaa.net...etc) setup?
Reason being is I want to be able to ping host names/connect through host names and able to resolve then using BIND as my main name server.

Basically, i want to be able to type a domain in my browser e.g. default.dev and it direct to the ../www/default folder on the Ubuntu Server on my network. The reason being is that as a web developer i have a number of sites that i'm working on locally and i'm getting tired of adding the domain to my hosts file and then creating a virtual host in Apache - i believe this can be done with BIND - is this right? If so what steps are required?

apt-get install libpqxx3-dev
From some tutorials I have read, I see I need to recompile it to enable its SQL support.
But when I do it that way, I won't get any security updates, won't I?
So... Is there any bind server with SQL support in the repositories ? For that I don't have to worry about security updates...
