I am using BIND9 and I wand to deny some queries per domain basis.Example: I don't want client1 to query the server for Ip address (A) for domain.comThe server should respond with an error, no such domain, nothing, etc.It's not authoritative for domain.com. I don't want the server to resolve recursive or iterative that domain.
View 3 RepliesI have registered 2 nameservers running bind for a certain domain. The log file of my domain name provider (SWITCH) shows the following warning:
Warning Der Name-Server ns.xxxxx.ch (nn.nn.nn.nn) beantwortet rekursive Anfragen.
In English that would be:
Warning: Name-Server ns.xxxxx.ch (nn.nn.nn.nn) answers recursive queries.
The NS triggering the warning is running openSUSE 10.2 and the other one 11.1. Both configuration files /etc/named.conf are equivalent (well, forwarders are different). There is no such warning for the NS with 11.1. When I add "recursion no;" to the options in /etc/named.conf the warning goes away, but FF or SeaMonkey running on the server no longer get their DNS requests resolved.

I have just updated PHP from 5.1.6 to 5.3.6
on CentOS 5.6, After reboot I have tried to install php-mysql
but I got error says code...
I have a NAS server running Debian with Dnsmasq (local DNS and DHCP service). This is working well, including fetching upstream requests from my ISP's DNS service and caching them locally. I have another PC not running Ubuntu which happily resolves DNS and non-DNS names. E.g.
Code:
ping hagrid.
ping hagrid
both work.
However, this is not the case on my Ubuntu PC. It is only able to resolve DNS names, not non-DNS names.
Code:
ping hagrid.
works but
Code:
ping hagrid
does not.

I'm installing ubuntu server 10.04 on HP Proliant DL140 G3, but in the partition part, HD doesn't appear.

Ubuntu website says HP DL140 is certified.
is it because lack of drives?
I'm confused. Why do I get a response from ping for any scrambled internet server name I type in??The only thing that is necessary is to start with "vvvvvv."(It should be triple W in this post, but I need to do this work around due to the forum rules )And it always resolved to different IPs with similar ping times.What's going on?

There seems to be some problem in my dns server.
The configuration is perfectly ok.But what happens sometimes is,
it couldn't resolve some domains sometimes.After restarting the
named,it again resolves the domain.
whats happening on my dns server
There's this domain, that is apparently a cname of a cname which is, I know, not recommended, but it's not forbidden by the rfc. The domain is [URL]. If I try with windows or bind dns I get this results in nslookup:
** server can't find [URL]: NXDOMAIN
but if I try with opendns I have some results.
> [URL]
Server:208.67.222.222
Address:208.67.222.222#53
Non-authoritative answer:
www.groenegordel.becanonical name = www.vlaamsbrabant.be.
www.vlaamsbrabant.becanonical name = waf.vlaamsbrabant.be.
Name:waf.vlaamsbrabant.be
Address: 193.53.37.42
With this I see it's a [URL] it's a cname or a cname. Is there a way to force bind to resolve this domain? Is this a limitation of bind?

I am no expert when it comes to BIND. I seem to be able to resolve NS and A and TXT records for my domain, but I cannot get the MX records to come out. Does anyone have an idea what might be wrong with my BIND zone file? I wonder if it might have something to do with the fact that my IP is currently on a policy Block List?

When i try to open any of my sites eg. kdelchev.com with my pocket pc (Asus P535) it displays carstatistics.eu, instead the site i want. Is that an apache misconfiguration? And what have to change to make it working?

View 2 Replies View RelatedWe installed CentOS 5 at our school and are attempting to get 2 simple DNS servers online. These are simple name resolution servers for our network. We installed the needed caching nameserver packages via Yum and all seems to be well, but for some reason when the server is online, it fails to resolve DNS records except when we direct the requests to its 127.0.0.1 (localhost) interface. As for the server specs, the DNS server is running on a Virtual Machine, and the ESXi server has 2 quad-core Xeon CPU's with 48 Gigs of RAM (in short.. hardware is adequate.)
Here's more details:
When the box boots up, we can confirm that the named service is running and it resolves DNS records when we direct queries to its localhost address:
[root@ns1 ~]# dig hotbot.com @localhost
; <<>> DiG 9.3.6-P1-RedHat-9.3.6-4.P1.el5_4.2 <<>> hotbot.com @localhost
;; global options: printcmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 55510

;; global options: printcmd
;; connection timed out; no servers could be reached
What would cause the Named service to not answer DNS queries from the physical IP but only from it's internal IP?
When I download fast and much my server freeze however if I don't download anything the server can run for weeks without problems but as soon I start downloading fast it doesn't take long until the server freeze again, I mean totally frozen so I have to manually power it down and then turn it on again. This started happening recently I think it started happening after I updated to 9.10 it have always worked perfectly before. Is there anyway to fix this? If not is there a way to downgrade back to 9.04 or 8.10 where everything were working fine?
View 2 Replies View RelatedI have recently downloaded and installed ubuntu 10.4, and I am finding it impossible to connect to the Internet.
I connect to the Internet through an Ethernet cable. My university (Tuebingen, Germany) provides the Internet through this server:
http://10.196.128.11/upload/custom/green/welcome.html (English link).
When I open my browser in windows vista (I have a duel-boot system), my browser (Firefox) automatically goes to this page, and I log in, and am able to then use the Internet.
Ubuntu also searches for this 10.196.128.11 server, but it continually states "waiting for server to respond". I have checked all the settings I could find in windows and compared them to the ones in ubuntu, and they seem to be identical to me. I am using firefox in ubuntu too so I cannot understand the problem.
I'm running Ubuntu 10.10 with all the updates. I'm in an NFS/NIS networked environment. My mounts eventually work, but mountall fails with this message in /var/log/boot.log:

I have an RHEL5 server running BIND. I'd like to be able to resolve internal, non-FQDN names such as "wiki" for the company internal wiki. in my named.conf file...Named-checkzone returns no errors, and nslookup works when specifying the server explicitly, but no browser resolves the name when entered in the address line. I know this by no means a standard use of BIND, but I'm sure someone out there's pulled this off. I did see when googling someone suggest "load the root zone (.) as master, and add your "hosts" as TLDs, using CNAMEs", but tried that and probably did it wrong since it didn't work.
