Server :: Named Not Responding To Queries
Feb 23, 2010My DNS server used to work flawlessly but for some reason it no longer responds to queries. It seems that named always queries internet root serves!!

CentOS 5 Networking :: Bind Server Not Responding To Client Queries
Mar 4, 2011I am bit new to Linux and have setup caching-only name server with Centos 5.5. when i do dig server, it provide resolutions. but when i use the server IP as DNS on my windows client, it says, "connection refused" on the NSlookup output. (IP table didn't enable) My server Ip is 192.168.1.253 and bellow is the configuration of "/var/named/chroot/etc/named.conf"
options {

Mar 14, 2009Mandriva 2009, BIND 9.5.0-P2. Named will start however I'm getting the above error as well as these:

Named shows to be running but with the errors above I know it's not running correctly. I also copied the above dir's over to /var/lib/named/var/lib/named which is where I 'believe' it's chroot'd at, though I could be wrong since I'm unfamiliar with chroot.

Aug 28, 2011How often are dns queries sent? Assume I want to connect to a ssh server, will I send one dns-query in order to do that or do I send multiple during my connection? What if I request web-pages, do I send a query only when I enter a site or will I send queries every time I visit a new page on that site?
I'm asking since I'm considering getting an account at dyn.com (the standard account for $30/yr) and it comes with 600 000 queries per month (which is way more than I expect to get but knowing exactly what it means is always good).

Server :: BIND 9.5 On Fedora Core 9 Not Resolving Dns Queries
Apr 21, 2010I have this ISP grade Nameserver running on BIND 9.5 on Fedora Core 9 64 Bit.
Its been pretty working well for sometime until a last week when we noticed it stopped resolving for our clients using on our service.
It gives correct authouritative answers for our own ISP domain with the A, PTR and MX intact but does not return resolving queries back to clients.
Below are my files
This is the message from /var/log/messages
The 41.223.x.x and 41.215.x.x ip address are from our ISP subnet and so are our own clients being denied.
The box is also hosting our traffic graph server which is on a LAMP but listens on another IP/ethernet card.
So far the load on the server is minimal as is a Dell R200 rack server.
Server :: DNS Merge / Intercept Queries From Zone File
Jun 4, 2010I chose -Server-, if this is more appropriate in -Networking-, just let me know. Basically, I need to be able to merge responses stored in a zone file with responses from an "upstream" authoritative server. I'm in the sad position of needing to "intercept" requests to *part* of a domain (but not restricted to a sub-domain!) and return results for *some* hosts that use an internally routed address, and results for the rest using the public internet addresses. Unfortunately, it's not my domain, so I can't just use views (although I suspect they could end up having some part to play in this, at least potentially)... but instead I have to actually send requests recursing to the other site's external DNS for any hosts my server doesn't have records for in the zone file.
Some background on the situation:
I work at a local government, which has a private link / VPN connection to a state government entity, and needs to use internal addresses for some of the state servers, which then get routed over an "internal" network link. But the state uses the same domain name internally and externally, just presenting views to internal clients vs. external clients. -- However, we are only being allowed access to certain of their servers through the internal link, which means that for any other servers that we don't have internal/private access for, we have to visit the public addresses just like anyone else on the internet... So, I can't just send all requests to their internal DNS and get responses, because we'd get IPs for some servers (e.g. their main web site) that we wouldn't then be able to reach using the internal network link.
For Example: Say I have a client machine, "client1", on my network ("my.net"), which uses "mydns1.my.net" for name resolution ... and which needs to access 2 servers on the state network, "private.st.us" and "public.st.us" -- so named based on how "my.net" needs to access them.
The external state DNS server/view ("ext-dns.st.us") responds to requests with something like:
private.st.us -- 1.2.3.456
public.st.us -- 1.2.3.457
(Those are just crap addresses, obviously.
The internal state DNS server/view ("int-dns.st.us") responds to requests with something like:
private.st.us -- 10.0.0.8
public.st.us -- 10.0.0.10
This works on their network because their own clients have access to all such IPs.
But for us, they only allow traffic flowing between "my.net" and their internal network to reach the 10.0.0.8 address, blocking all other address destinations. So, when "client1.my.net" asks "mydns1.my.net" for the address of "public.st.us", I need "mydns1" to recurse out to "ext-dns.st.us" to get an answer (1.2.3.457) and then return that IP to "client1" -- because "my.net" is blocked from accessing the server's 10.0.0.10 address. But, when client1 asks mydns1 for "private.st.us" I need to pull the IP (10.0.0.8) from a local zone file instead of asking either of the state DNS servers -- or optionally forward the request to "int-dns.st.us" I suppose -- because the state blocks access to certain services (which we need and are the whole cause of this problem!) via the public (1.2.3.456) address.

CentOS 5 Server :: Dnsmasq Starts But Doesn't Reply To Queries

Jul 19, 2010I 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.

Jul 14, 2010I've got a machine running Ubuntu Server that is on several VLANs. Each VLAN has its own subnet and the server has an address on each subnet. The switches are set to allow tagged traffic to the server for each VLAN that it is on. Switch ports ending with workstations are given untagged ports on whatever VLAN is appropriate. Workstations are given addresses on a subnet for each VLAN via DHCP. All this works great and hosts on any subnet/VLAN can access the server as normal via its address on that subnet/VLAN.
Accessing the machine by its address on a non-local subnet is where I run into a problem. Inter-subnet traffic has to go through a router, which has been set up appropriately. Running tcpdump on the server and pinging it from a workstation on a subnet, using its address on a different subnet, shows the server receives the ping, but sends no response:
Code:
sudo tcpdump -i vlan4 -n
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode

Server :: Deadlock In NFS4 / Shared Servers Suddenly Stop Responding And Cant List It From Debian 5 Server?
Jan 4, 2010I am connecting servers using NFS4 the shared directories are on servers running Debian 4 while the one who read from them is Debian 5.0.3. The problem is one of these shared servers suddenly stop responding and you cannot list it from Debian 5 server, also df hang, and the web application that is using it does not respond to requests that use this shared directory since it is blocked. Then the load on the server start to increase until the server cannot respond (over 90). I have found many entries in the syslog that refer to this like:
ma25555 kernel: [1200285.732919] nfs: server 10.xxx.xxx.xxx not responding, still trying
Dec 31 08:16:33 ma25555 kernel: [1200289.815378] INFO: task java:9702 blocked for more than 120 seconds.

I have tried the connection between the 2 servers using ping for one day and all are OK (zero lost)
