Bind Isn't Working


bind in my server isn't working and when I restart it on cPanel this is what I get:

Restarting Bind

And so on... for a lot of domains configured on this server. I don't think it loads all of them.

Then, right after seeing this problem I tried to connect to SSH while googling the problem and I got this:

BIND
I have managed to install BIND 9.4 on my home web server so that i can have my own domain (one that i can manage). I have made a domain with it called h2o-cms.org, the domain will work when i connect to it from my home lan but if i use a cgi proxy to connect it can't be found.

I'm using Windows XP

This is my named.conf

Code:
// Config file for caching only name server
acl "friends" {
localnets;
127.0.0.1;
};
options {
directory "C:
amedetc";
version "SERVFAIL";
allow-transfer { none; };
allow-recursion { "friends";};
// Uncommenting this might help if you have to go through a
// firewall and things are not working out. But you probably
// need to talk to your firewall admin.
query-source port 53;
};
zone "." {
type hint;
file "named.root";
};
zone "0.0.127.in-addr.arpa" {
type master;
file "locals.hosts";
};

zone "h2o-cms.org" {
type master;
file "h2o-cms.org";
};
this is my h2o-cms.org file

Code:
$TTL 600
; h2o-cms.org
@ IN SOA laxlxns01.h2o-cms.org. hostmaster.h2o-cms. (
2005062601 ; serial

)

@ IN A 80.46.117.13
; host records
localhost IN A 127.0.0.1
www IN A 80.46.117.13

I have forwarded the port 535 to the server too

Bind
Not sure if this is the right place - sorry if it isn't. Recently, I got really pi**ed off with cPanel - and have decided to try and load my server without it.

I'm using Webmin/Usermin/Virtualmin with Apache, PHP, MySQL, proftpd, and BIND.

But I'm not entirely sure on how to create nameservers on BIND - I've looked all over the internet, but have found nothing helpful.

DNS And BIND 9
i work in a new ISP company, and ive been assigned to the DNS server, and before this i have never even heard of BIND, but now im in need of learning it ....and im only fairly familiar to Linux..so here are me questions:

1. where can i find a beginners guide to DNS and BIND?

2. what distribution is best suited for the server?

3. are there any default templates for the BIND config files that one could start with and modify?

4. how many files are there? i mean every time a read a bit about BIND pops up a new file name.. so how many files are enough?

5. would any1 care to help me out step by step throught my ordeal?

6. are there any training courses that i could take? are there any onlline ones? or videos that i could grab off the net?

7. how many times does a swallow have to flap its wings to maintain airspeed velocity in order to carry a coconut?

Broken BIND
I ran "yum update" on one of my servers, and it must've updated BIND, because now named doesn't start.

I basically hit all the problems in this thread:
[url]

This is CentOS4 with Plesk.

Even though I don't have that package installed, and tried every suggestion there, it still doesn't start... I mucked with the configs and moved so many files I don't know how to get back to where I started.

Quote:

Jul 24 05:08:06 www named: /etc/named.conf:67: open: /etc/rndc.key: file not found

What's my best bet for fixing this mess? I sent in an e-mail to two "server administration" companies I found in signatures here, hopefully one of them will be available today.

I changed the nameservers on critical domains to a free DNS service to get them back online, but they're acting oddly (like DB timeouts), perhaps because of the lack of a local nameserver to talk to.

But in the meantime is there anything I can do to try to fix this quick?

Weird Bind
I have a weird problem since the movement of our ip range with one of our servers. Bind doesn`t seem to react on any changes we make.

For example, the server still resolves to the old ip adress while we changed all of those with ipswap.sh (directadmin)
The weird thing is that all zone files are 100% Correct. Ip`s are all changed and no sign of the old ip whatsoever.
Again, the nameserver still resolves to the old ip`s.

Also when i create a new domain, named.conf is changed and the zone file is created sucessfully. Still the nameserver doesn`t seem to add the domain name.

Restarting, reloading and even reinstalling named doesn`t help

Bind 2 DNS Name To Same IP
if it is possible to bind 2 NS to the same IP

For example, I previously had n1.abc.com , ns2.abc.com bind to certain IP. Now I registered another domain name, say abcdummy.com at another reseller and was given the option to choose my private dns. But instead of ns1.abcdummy.com and ns2.abcdummy.com, I thought this name doesn't sound that nice to be an NS. So I asked for ns3.abc.com and ns4.abc.com

Which has been registered and propogated successfully. But I want to move these domains on abc.com to abcdummy.com server, as i will not be using my reseller package at abc.com any more

So now, but its a lot work to do if I was to change these domain name NS one by one. So could I instead bind ns1.abc.com and ns2.abc.com to the same IP as ns3.abc.com and ns4.abc.com

Bind Keeps Failing
For some reason BIND keeps failing on my cPanel server every couple of days. There are no error logs in the /var/logs/messages file concerning the crash but when I manually restart bind then it logs messages just fine and I can see them. Does BIND keep any other error logs?

Today it seemed to coincide with a big movement in system memory, here my munin graph:

I have ran the “fixeverything” script which attempts to correct any errors in the bind config file but it still crashes. I couldn’t see anything wrong with it ayway.

Bind Exploit Rumor
There has been some hacker group out there on the net hacking lots of servers. Some of which I knew the admins/owners and they were not stupid people and kept their server up to date as well as using grsecurity kernels, selinux, assorted firewalls, etc. In other words they done what most of us do trying to keep their server as secure as possible.

But it done them no good as the hackers were able to get root access in minutes on linux and freebsd servers. After looking into it and asking around supposedly these hackers have a 0day remote root exploit for bind.

Anyone heard of this and does it seem plausible?

The bind that comes with cpanel and directadmin is BIND 9.3.3rc2 which is pretty old even compared to default rhel packages which are 9.42 now. Does anyone know why cpanel and da have bind excluded form being updated in yum? And what would be the harm in upgrading? Has anyone here upgraded their bind?

Can BIND Query Another Nameserver
I've got mydomain.com using my own BIND nameserver hosted on a dedicated server.

I need subdomain.mydomain.com to have a dynamic IP. I know many dynamic DNS providers, but they all require you to change the nameservers of your domain to their own nameservers. Unfortunately I cannot do this - I need mydomain.com to keep using my nameservers.

I therefore need a way to get my nameserver to query a dynamic DNS providers' nameserver for subdomain.mydomain.com. Esentially my nameserver would just copy the IP that the other nameserver returns. Can BIND do this, or if not, any other name-server software?

Bind Somehow Changed After Cpupdate
We already ran our servers for a few years and never experienced a problem like this.

Our domain registrar REQUIRE correct nameserver setup, even the number of nameservers, before they register a new domain but after the last cpanel update (manually to both stable and then release) nameserver 4 don't respond.

With starting bind I got the following/

eth1:1, xx.xxx.xx.83#53 Jun 15 08:29:50 mercury named[17599]: listening on IPv4 interface eth1:2, xx.xxx.xx.84#53 Jun 15 08:29:50 mercury named[17599]: listening on IPv4 interface eth1:3, xx.xxx.xx.85#53 Jun 15 08:29:50 mercury named[17599]: listening on IPv4 interface eth1:4, xx.xxx.xx.86#53 Jun 15 08:29:50 mercury named[17599]: command channel listening on 127.0.0.1

Dig from within the system gave the correct results but dig from outside give a timeout error on nameserver 4.

[url] also don't show any results while [url]works correctly. (RDNS is correct and IP address point to ns4.sa-servers.net)

Bind Zone Limit
I'm curious if there is a limit to the number of DNS zones that Bind can read.

Is there a limit to where performance starts to become an issue?

Would Bind be able to handle 10,000 DNS zones? What about 20,000 or 30,000?

I seem to recall reading something that said Bind was only able to read a certain number of zone files. But I don't remember where I read that, and it may have been several years ago.

Cpanel: Bind/named
I try to set up my VPS.

I couldn't set up any domain because I always got the error "Sorry, a DNS entry for domain.com already exists, please delete it first (from all servers in the dns cluster)".

Then I realized that it's because there was no named.conf. So I tried to make a named.conf myself (I took a named.conf from another server and changed it a bit)... at least I could add DNS Zones and domains now. But it still wasn't working very well.

Is there a way to build named.conf by fedora or cpanel?

Have I Got BIND Domain Name Server (DNS) Right?
Ive been learning alot about BIND and DNS, id like someone to check over what ive learn't to make sure my knowledge is correct.

A Zone:

A zone is basically 'similar' to a sub-domain but the domain google.com would not be a sub-domain, so a zone is not a sub-domain. In the domain google.com 'google' would be a deligated zone from the TLD 'com'. In another example: ny.google.com , 'ny' would be a zone for google's 'new york' department, if they had one.

Hosts:

The host name is usually the most left word in a domain or you can look at it as the leaves on an inverted tree in the DNS System. Examples:

www.google.com = 'www' would be the host
mail.sitepoint.com = 'mail' would be the host
ny.google.com = 'ny' would NOT be a host because its a 'zone' and does not offer a 'service' like ftp, mail, www ect. would. Unless 'ny' was intended to be a service then it would be a host, but it would have to become a leaf in the inverted tree, so you wouldn't ba able to create any zones from it like 'mail.ny.google.com' ... if that makes sense.

Nameservers:

If i used BIND on my server to manage my Zones and DNS information (which is pretty much standard), that would be my Nameserver. Its job would be to convert human recognizable names into computer recognizable names/numbers/ip.

My nameserver would only have authority over zones that are not deligated. So an example, 'com' deligate 'mydomainname' to me (mydomainname.com) they have no authority over that zone. So if i set up a nameserver on mydomain.com they have no authority over mydomainname or any zone under that.

Domain Namespace

The Domain Namespace was setup to replace the method used by ARPA (later DARPA) in the 60's in an effort to create a database of hosts that were easy to administer and reduced the time and server load on the old skool HOSTS.TXT method.

A domain namespace is a way to identify the different domains. Im not to good at explaining what i mean but basically ill illustrate this example:

google.com and google.net both have the same names, so the namespace in this example would the the TLD's 'net' and 'com' to seperate them.

Go a bit deeper for example:

cd.music.com and cd.disk.com , both have the same TLD and sub-domain's so the namespace here is the first-level domain 'music' and 'disk'.

Sub-Domains
Sub-Domains are similar to zones, in a way. A domain name: 'google.com' might have the sub-domain 'video.google.com' which links to the video section of google. 'video' is not a deligated zone from 'google' neither is it a host as such, so its a sub-domain.

Im probably slightly confused on some parts, and im open for comments. I dont fully understand alot of it, but what ive learnt so far took a good day to get my head around. If anythings wrong, id like to know.

DNS Poisoning - Is Your Bind Up To Date
Vendors form alliance to fix DNS poisoning flaw

An alliance of software makers and network-hardware vendors announced on Tuesday that they had banded together to fix a fundamental flaw in the design of the internet's address system.

The vulnerability in the domain name system (DNS) - the distributed database that matches a host and domain name with the numerical address of a computer server - could give an attacker the ability to replace the addresses of popular websites with that of a malicious server, said Dan Kaminsky, director of penetration testing for security firm IOActive. Kaminsky found the flaw when he was doing non-security research on the domain name system (DNS) more than six months ago.

"It is a fundamental issue affecting the design," Kaminsky said. "Because the system is behaving exactly like it is supposed to behave, the same bug will show up in vendor after vendor after vendor. This one bug affected not just Microsoft ... not just Cisco, but everyone."

On Tuesday, a number of software and network-hardware vendors released patches for their products. On its regularly scheduled patch day, Microsoft released updates for Windows 2000, Windows XP and Windows Server 2003 to mitigate the issue, which the company ranked an important vulnerability, its second highest grade of severity. Internet Software Consortium, the group responsible for the development of the popular Berkeley Internet Name Domain (BIND) server, also released a patch, confirming that its software contained the vulnerability. Both Cisco and Juniper also acknowledged flawed systems.

Vendors have also provided the fix to certain large clients. Yahoo will be upgrading its name servers from BIND 8 to the latest version of BIND 9, the Internet Software Consortium stated during the conference call. Internet service provider Comcast has already patched its servers for the issue, according to internet infrastructure firm Nominum. Finally, the Computer Emergency Response Team (CERT) Coordination Center has contacted some other nation's response groups to inform them of the problem.

For the most part, however, internet service providers and companies each received the fix on Tuesday, said Sandy Wilbourn, vice president of engineering at Nominum. The goal: To have every major service provider and company apply their software patches in 30 days.

For that reason, don't expect immediate action, Wilbourn said.

"For key customers on our network, we have made a special effort to get them an early release to help solve this problem, and a number of them have finished deployment," he said. "But the nature of this patch is that we wanted to get the vendor side covered and then have deployment over the next 30 days. Anyone that is not patched by today or tomorrow is not doing anything wrong."

The domain-name system (DNS) has been a popular way to attack the internet in the past - it's an ill-kept secret that the DNS system is insecure. The way that many software applications, such as browsers, handle DNS requests has opened up users to attack. Microsoft has fixed a few vulnerabilities in the way Windows handles domain names - issues that could have lead to easier eavesdropping or simpler phishing attacks.

Bind Taking Up 200+ RAM
I installed Direct Admin on my 192mb RAM vps and right now my VPS is at 270mb (I'm going into burst). I found that if I stopped named, it goes down to less than 70. Why is Bind taking up so much RAM?

ISC Bind On Windows - SERVFAIL
i had a webserver setup that worked perfectly, but due to circumstances i had to reinstall windows. so i reinstalled windows updated everything and installed bind again.

i configured it properly and the zone is also setup properly but when i try to connect to my url it wouldn't connect. so i did a dns lookup and i get SERVFAIL.

[www].dnswatch.info/dns/dnslookup?la=en&host=xeross.net&type=A&submit=Resolve
remove the [] from the url.

How can i solve this i reinstalled once again and it still doesnt work i forwarded all correct ports and added them to my firewall exceptions.

Attached are my named.conf, rndc.conf and my zone file.

I added .txt to the named.conf and rndc.conf so i could upload them.

Bind $GENERATE Statement Overriding
I am configuring a bind reverse DNS zone to use the $GENERATE statement. This works well. But If I add a single IP record after or before the $GENERATE statement I get 2 PTR records for that IP (which is expected I guess).

Does anyone know if it's possible to report only 1 PTR record for a single IP (host) record?

BIND + Dovecot - Can't Get To The Mail Server
I have a what seems like a quick question. I'm hosting my own DNS servers via bind, and everything seems to be nice and dandy. However, I cannot seem to receive email, and when I do a check via pingablity it tells me there is a timeout error when trying to reach my MX record. I *am* able to access the POP/IMAP server (which is powered by Dovecot) through Outlook and other email clients.

I know it is an issue with iptables because as soon as I turn it off pingability is able to reach my mail server just fine. I do have port 53 open as well as 1024-65535 UDP ports open. I've scouted internet for hours trying to find the cause of the problem with no results.

My CentOS 5 Bind Installation Commands
if after doing the following and transferring my domains to the server, they will functions properly as far as BIND setup is concerned. This will also serve as installation instructions for others if you can verify that this is all good.

I have installed BIND9 and setup DNS with the following:
------------------------------------------------------------------------

yum install bind-chroot

chmod 755 /var/named/
chmod 775 /var/named/chroot/
chmod 775 /var/named/chroot/var/
chmod 775 /var/named/chroot/var/named/
chmod 775 /var/named/chroot/var/run/
chmod 777 /var/named/chroot/var/run/named/

chown -R named /var/named/chroot/etc

chown -R named /var/named/chroot/var

cd /var/named/chroot/var/named/

ln -s ../../ chroot

cp /usr/share/doc/bind-9.3.3/sample/var/named/named.local /var/named/chroot/var/named/named.local

cp /usr/share/doc/bind-9.3.3/sample/var/named/named.root /var/named/chroot/var/named/named.root

touch /var/named/chroot/etc/named.conf

chkconfig --levels 235 named on

named.conf now contains:

Code:
options {
pid-file "/var/named/chroot/var/run/named/named.pid";
directory "/var/named/chroot/var/named";
query-source address * port 53;
allow-query { any; };
recursion no;
};

zone "server.mydomain.com" { type master; file "server.mydomain.com.db"; };
zone "mydomain.com" { type master; file "mydomain.com.db"; };
zone "mydomain.net" { type master; file "mydomain.net.db"; };
Upload named.conf to /var/named/chroot/etc

Modify /etc/resolv.conf to have the following before its current data:
search mydomain.com
nameserver 127.0.0.1
nameserver 78.129.143.155 // Replace this with the server's IP
// So below these there should be one or more nameserver $ip that point to the ISP's name servers so that the server can download stuff.

Modify /etc/host.conf to become the following:
order hosts,bind
multi on
nospoof on

Modify the files mydomain.com.db and mydomain.net.db and server.mydomain.com.db
to have the correct IP address. (These are DNS zone files that I'm sure are correct so I don't need you to confirm those.)
* Upload them to /var/named/chroot/var/named

/etc/init.d/named start

Open Domain Name Server (DNS) - BIND
Just being doing a load of DNSstuff.com queries to try and get everything to "pass", I noticed that some big players in the hosting scene have either open or closed DNS servers.

Softlayer.com have closed, while liquidweb.com are open...?

I have changed all mine to closed, just because dnsstuff advises it, but is there any reason you would want them open..?

Bind DNS Reverse Lookup File
I'm having tons of problems trying to get reverse lookup working on my dns server. I've scoured the net and tried lots of methods but so far none work.

Forward lookup DNS is working perfect, but reverse lookup is completely broken.

db.44.80.212.67:

Code:
$TTL 86400 ; Default TTL in secs(1 day)
@ IN SOA ns1.capturetheprize.com. info.capturetheprize.com. (

2009072902; serial number YYMMDDNN
28800 ; Refresh
7200 ; Retry
864000 ; Expire
86400 ; Min TTL
)

IN NS ns1.capturetheprize.com.
IN NS ns1.mytempmail.com.

; Reverse lookups
44 IN PTR ns2.mytempmail.com.
44 IN PTR ns1.mytempmail.com.
44 IN PTR ns2.capturetheprize.com.
44 IN PTR ns1.capturetheprize.com.
44 IN PTR mail.mytempmail.com.
44 IN PTR mail.capturetheprize.com.
44 IN PTR stats.capturetheprize.com.
44 IN PTR secure.capturetheprize.com.
named.conf

Code:
zone "80.212.67.in-addr.arpa" IN {
type master;
file "etcdb.44.80.212.67";
allow-transfer { localhost; };
};

I create two master zone for a.com and b.com
a.com

Code:

$ttl 38400
a.com. IN SOA server.a.com. abc.yahoo.com. (
1226206691
10800
3600
604800
38400 )
a.com. IN A 1.2.3.4
server.a.com. IN A 1.2.3.4
a.com. IN NS server.a.com.
mail.a.com. IN A 1.2.3.4
ftp.a.com. IN CNAME a.com.
www.a.com. IN CNAME a.com.
a.com. IN MX 10 mail.a.com.
b.com
Code:
$ttl 38400
b.com. IN SOA server.a.com. abc.yahoo.com. (
1226206691
10800
3600
604800
38400 )
b.com. IN A 1.2.3.4
server.a.com. IN A 1.2.3.4
b.com. IN NS server.a.com.
mail.b.com. IN A 1.2.3.4
ftp.b.com. IN CNAME b.com.
www.b.com. IN CNAME b.com.
b.com. IN MX 10 mail.b.com.

APACHE

========================

I created 2 virtual servers for a.com and b.com
/home/sites/a.com/html
/home/sites/b.com/html

I create an index.php in a.com/html with content: "a.com YEAH"

I create an index.php in b.com/html with content: "b.com YEAH"

After wait for dns to propogated,

when i try to go to a.com, content "a.com YEAH" shows up.

But when goto b.com, content "a.com YEAH" shows up? Why?

Also, when goto ns1.a.com, content "a.com YEAH" is there.

I also has problem with vsftpd but let fix that later.

DNS Servers, Moving From BIND To TinyDNS.
I currently have 2 DNS Servers with CPanel-DNSOnly Installed, used with CPanel's DNS Clustering options to store dns entries from CPanel web servers.

I am looking to buy a Windows server(probably with plesk), which i think will not support current CPanel DNSOnly Servers ?

What i need to do is

1. Migrate CPanelDNSOnly(which uses BIND) to TinyDNS on both servers

2. with a simple web-based management of dns entries(to give control to my clients, like DomainDNS.com)

3. and auto updating of DNS Entires from other CPanel and Windows servers, without conflicting same domain records from different servers (which i think can be solved by updating entires by Latest Modified date/time).

I am not an expert, and not really sure if i will be able to setup everything myself. here i need your help, guidence, and links to tutorials and help... From where should I start? What and How should I do? Should I consider hiring a System admin? any sugestions or reference for such admins?

Error: Missing Dependency: Bind During Yum Upgrade
