Software :: Bind9 Dynamic Zone Not Reloading?
Apr 13, 2010
I have a dynamic-dns setup that updates from DHCP. In my reverse zone file, I have some mappings that are more or less static (as in, outside of the DHCP range that updates to dhcp-<ipaddr>.domain.tld)
When I add new records to this zone and then reload the zone file (making sure to update the serial number), the name server still does not serve these new records. For example, I might add the following to my 168.192.in-addr.arpa. zone under the $ORIGIN 25.168.192.in-addr.arpa. section:
Code:
45 IN PTR new-host.example.tld.
I then proceed to try:
Code:
rndc reload
/etc/init.d/bind9 reload
[Code]....

The thing is, I've created a new local zone here (called "local.lan"), and, aparently, it is working fine, and DHCP3-SERVER is updating DNS info through the controls.But sometimes I get some strange answers from the server, like when I do the "arp" command in one of the clients, and get the server's hostname "mixed" with it's own reverse, like this: "dns.local.lan.2.168. | ether | 00:02:1e:f5:61:74 | C | eth0". Other thing is that sometimes my DNS don't update when a computer "enters" the lan. In the /var/log/syslog the DHCPOFFER appears, but the information about the DNS update isn't there.So, I would like to show you my named.conf file and my local zone db file, and get some feedback from you (what would you change... what is wrong...).

I am trying to get bind 9 up and running on a new installation of server 10.04 and keep getting errors when starting the daemon -
* /etc/bind/named.conf.local:19: unknown option 'zone'
* /etc/bind/named.conf.local:20: unknown option 'zone'
* /etc/bind/named.conf.default-zones:3: unknown option 'zone'
* /etc/bind/named.conf.default-zones:11: unknown option 'zone'
* /etc/bind/named.conf.default-zones:16: unknown option 'zone'
* /etc/bind/named.conf.default-zones:21: unknown option 'zone'
* /etc/bind/named.conf.default-zones:26: unknown option 'zone'
The onlything I could find after scrubbing the internet is once ina while there's a missing bracket. But I have checked and triple checked my config files and the syntax and can't find anything wrong. I have another installation of bind9 running on Fedora and the same exact syntax works just fine.

I've configured my dhcp server to update dynamically the DNS zones of BIND9 name server. Everything works ok, except for reverse nslookup:
nslookup 10.141.50.3
Server:127.0.0.1
Address:127.0.0.1#53

I'm at a loss to why my reverse lookup zone doesn't work for me.I've got two views. One internal and one external. My domain is isp2.datornatverk.se. Public IP: 130.240.133.81.
dig -x @8.8.8.8 130.240.133.81
gives me:
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NXDOMAIN, id: 2917
;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 1, ADDITIONAL: 0
I've set it up so that the internal subnets gets the domains resolved to the internal IP-addresses. When querying from external addresses I will get public IP.My named.conf.local file:
Code:
acl internals {
127.0.0.0/8;[code]..........
I don't know whether the views has messed something up. It worked before I added the views.

I reload the indexpage of the General Help forum, the screen view is not the same as what it was. When I read the indexpage the first thread is listed at the top of the screen, I scroll down to have that.After reloading I see the top of the page on top of the screen and I have to scroll down again.This used to be different. It used to be after reloading the page I would get the same view.See attached pictures to see what I mean. The first one is the view I like to see, the second is what I get after reloading the page.Is this something which is caused by software in my computer, or is this dne on the website side?
I use Mint 9, related to Lucid 10.04 in 64 bits version and Google Chrome as webbrowser. To reload pages automatically I use the plug-in Autoreload and have it set at 10 seconds.I just saw in Firefox it works good, so it must be Chrome.I also placed this thread in the "Forum Feedback and Help" forum but since that is a less popular forum I want to place it here.

I have to do but wanted to check first before I started messing around with my MBR.
Originally was running XP and installed WUBI 9.10 to play around with Ubuntu before doing a proper install. Got home from work tonight and removed WUBI leaving edited MBR with WUBI boot loader. I thought I might have to run fixmbr before installing Ubuntu but I assumed Ubuntu would write over WUBI edited MBR. Installed Ubuntu 9.10 and everything is fine but when I select XP from first boot option (Ububtu) it then takes me to another boot option which was from the WUBI install.
Basically to get to XP, I have to select it twice.
It's not a big issue but I know that this will annoy me and one day or another I will try and remove the second unnecessary option to boot into XP.
So if I have this correct I will need to run fixmbr from XP disc and then install Grub 2.0 from Ubuntu disc somehow?
Is this right? Is there another way I can delete the second boot option screen?

I had to reload my XP partition and my grub menu disappeared. I followed direction from this web page [URL]. I followed Method 1. After I rebooted I got a command prompt with a notice stating Minimal BASH-like line editing is suppoerted. When I input the final command of sudo update-grub I get the unknown command error. I cannot get to either XP or Ubuntu is there anything I can do short of reloading my ubuntu?

I'm running WiFi AP (hostapd/nl80211) and STA (Wicd) in my home net. More or less all does work fine at last. The only problem I have - STA reconnection works few times only (1-4 times), ending with unsuccessful authentification (and multiple AP probing in hostapd debug output before STA failing).Two contradictive facts take place:
1. Reloading hostapd on the AP side permits Wicd to reconnect, while STA rebooting(!) doesn't help.
2. Another STA - my son's Nokia mobile phone (don't know a model) - reconnects with this AP without problems (we have tried 10 times).
So, you see, first fact says something wrong with AP, while the second one says something wrong with STA. Or you can treat these facts in strictly opposite way Indeed WiFi under Linux is very fragile area yet. I have found plenty of close-to-be-similar reports as well as different resolving ways (but it is rare case).OK, few words about setup. Up to date Kubuntu Maverick testing with backports enabled on both sides. ASUS USB-N11 adapters are in use on both sides. It means RT2870 chip.

I have Slackware r13.0 32 bit installed, and I'm interested in getting SNORT installed with Barnyard and BASE to learn about IDS using my own home network. I'm following a guide found here:
[URL]
I'm having trouble getting past the "create the BASE tables" section. Everything up to that point seems to have been functioning properly. When I attempt to login with my username/password, I get rejected.
The httpd error log reports the following:
[DATE] [error] [client] user snort not found: /frontend
I can manually get into the mysql database with this username/password combination. I've been working on this on and off again for the past few days, and I forgot what led me to the mod_auth_mysql.so module, but I remember reading some posts elsewhere that pointed to this module. I found the source, and used apxs to compile and install it. However, when I insert the "LoadModule mysql_auth_module modules/mod_auth_mysql.so" line into the httpd.conf file, I can't restart the httpd service, and I'm given this error:
httpd: Syntax error on line 117 of /etc/httpd/httpd.conf: Cannot load /usr/modules/mod_auth_mysql.so into server: /usr/modules/mod_auth_mysql.so: undefined symbol: mysql_select_db It seems that the frontend URL on my server is attempting to use php to authenticate to the mysql database. Am I on the right track here? I've seen other posts with similar problems, but they recommend re-installing either mysql or php from the slackware site, but the Slackware package browser site (http://packages.slackware.it/) is down until a new one is written from scratch.

I have a web server on my local network with a couple domains facing the internet. When I visit these domains from within the network I'm directed to my routers configuration page due to hairpin NAT.
So I installed BIND9 on the server and set up my forwarders to Google DNS to act as a Caching Nameserver. Then I set my routers DNS primary and secondary nameservers to the IP of the local BIND server. Everything is working great.
Now I need help configuring BIND so that the domains hosted on the web server within the network are routed to the web server and not the routers configuration page.

Set up a server with Bind, Dovecote, Apache etc. Registered a domain and made all the necessary things for it to work. The server can send/receive mail on my domain, but when I try to look up the site I have it returns a lookup failure. I know Apache is working as I can browse the site when I used my ip address but I can't when I use the domain name. Anyone got a few tricks I could try to dumb down and find the possible failures I did when setting this up?

I have Ubuntu 9.10 PC on my home network acting as a VPN gateway. It is using vpnc & iptables to provide access to the remote network - other computers on my local network have routing rules in place to go via the Ubuntu gateway if trying to reach an IP on the remote network. This works just fine, except DNS lookups for names on the remote network don't work.
I'm trying to solve this by using Bind9 on the gateway, so it can act as DNS for the local network. I don't want to create excess VPN traffic or load on the remote DNS, so I want the gateway to forward the lookup to my ISPs DNS first and if the name is not found then try the remote network DNS. Is this possible, or is there another (better) way around this? The Bind9 configs seem to admit multiple DNSs, but use them in a failover sense - only using secondary DNSs when the first one in the list is not reachable at all.

using Ubuntu Server 10.10 x86_64 on this machine. It is used as a master DNS server for my domain. We have migrated it to Ubuntu from Gentoo. The problem is that AppArmor is spamming /var/log/syslog
Code:
Jan 3 14:38:40 hydra kernel: [2154828.893409] type=1400 audit(1294061920.141:660146): apparmor="DENIED" operation="mknod" parent=1 profile="/usr/sbin/named" name="/var/log/named_querylog" pid=15397 comm="named" requested_mask="c" denied_mask="c" fsuid=103 ouid=103
The zone files reside in /etc/bind/ and we have not changed anything in /etc/apparmor.d/usr.sbin.named .
We don't want to just uninstall apparmor, but how do we adjust its settings correctly?

Since I have not gotten anything on the "General Help" I am posting this here: When a Ubuntu 10.10 I have starts up apache2, MySQL and postfix start properly but bind9 doesn't. Once booted is I run 'sudo /etc/init.d/bind9 start' it starts. The only thing odd on this system is I have a "inet6 v4tunnel" interface defined in my /etc/network/interfaces. From booting in the syslog there is:
Code:
/var/log/syslog:Feb 28 19:02:42 ubuntu named[1029]: starting BIND 9.7.1-P2 -u bind -d 9
/var/log/syslog:Feb 28 19:02:42 ubuntu named[1029]: built with '--prefix=/usr' '--mandir=/usr/share/man' '--infodir=/usr/share/info' '--sysconfdir=/etc/bind'
[code]....
Even with the bind debug level at set at 90 I do not get any more in the logs that what I posted before. The lack of errors in the logs is giving me no idea where to start. I commented out the IPv6 tunnel interface and rebooted and still no help. bind still is not starting at boot. OK, it is not a permissions issue, I have changed the config and zone files to be owned by bind:bind, root:bind, root:root and bind:root and it has made no difference. Doing a fresh install on a Virtual Box VM and configure it in a similar manner bind9 starts normally. (I am almost to the point where I will rebuild the box)

when i try to set up bind9 to resolve the top level of the name it cant do it. for current sake of arguement i have 4 servers on the network
192.168.0.200 diana.undernets.lan
192.168.0.201 jen.undernets.lan
192.168.0.202 amanda.undernets.lan
192.168.0.203 alex.undernets.lan
those are the IP addresses of the servers and their respective hostnames
so if i send a request for anything to just undernets.lan it will fail because there is no record for that. so i added this to the bottom of the zone record
Code:
IN CNAME amanda
thinking that a blank would refer to the top of the zone
here is my named.conf.local which is called in my named.conf
Code:
zone "undernets.lan" {
type master;
file "/etc/bind/undernets.db";
};
zone "0.168.192.in-addr.arpa" {
[Code]....
i want to be able to lookup undernets.lan and it give me the IP address of amanda.undernets.lan

I'm trying to configure bind9 to block porn by having it pretend to be authoritative for a list of porn domains. It can then return a "fake" IP for the port sites, which points to a page on my server. So far, the only way I have found to do in this in bind requires a separate zone for each porn domain. This doesn't work because of memory problems - I have 1000's of porn domains to block.
I'd like to instead have bind forward queries to rbldnsd, which can take a list of domains in a "data set" file, and use it to return a single A record (pointing to my "access denied" page). However, I think this will not work because I would still need a separate "zone" for each porn domain name.
