Debian Configuration :: DDNS (dhcp+bind9) - Wrong PTR Records In Reverse Zone?

Jun 3, 2011

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

Server :: Ddns Reverse Zone Updates Add Subdomain Twice To Each Entry?

Mar 8, 2011

I've run into a strange issue with a DHCP/DDNS setup whereby when the DHCP server asks the DNS server to add a new host, the forward map is added correctly but the reverse map has the subdomain added twice (e.g. 192.168.25.192.168.25.250)I'm running ISC DHCPd version 3.0.1 and BIND version 9.2.3 on SuSE 9.2 - 32bit.Here is my dhcpd.conf file:

# dhcpd.conf
authoritative;
include "/etc/named.keys";

Debian Configuration :: Bind - DHCP And DDNS ?

Jul 14, 2011

DHCP I have working, so is BIND.

I'm trying to get dynamic dns working and am having issues

I suspect this maybe a chroot issue.

I've tried to follow the chroot advise within the wiki for Bind but no joy.

Ubuntu Servers :: Bind9 Views - Reverse Lookup Zone Doesn't Work ?

Apr 1, 2011

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.

Server :: Can't Resolve MX Records - Zone File?

May 30, 2011

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?

Server :: BIND9 Conf And Zone Files?

Sep 20, 2010

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...).

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

Networking :: Bind9 : Reverse Lookup And PTR Value?

I have the following bind9 configuration, and I'm trying to resolve reverse lookup IP address to name.

$ttl 38400

[code]...

** server can't find 1.2.3.4.in-addr.arpa: NXDOMAIN

Is my PTR wrong, or what do I need to have the reverse lookup working ?

Note: I replace real IP by 1.2.3.4, same for my domain name.

Ubuntu Servers :: Bind9 Errors: Unknown Option 'zone'

Aug 11, 2010

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: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.

Debian Configuration :: Reverse Notebook Function Keys To Default (no Fn)?

May 17, 2011

The top row of keys on my notebook are currently assigned to various media functions (brightness, volume, play, stop, etc.) These keys are rarely used, and it would be better if they were assigned to the function keys (f1,f2,f3,...) by default, rather then using the fn key to access them. Locking the fn key down is not an option. What can I do?

Debian Configuration :: Apache Reverse Proxy - No Support For Common Database

Apr 14, 2010

I installed apache2 and mysql database on a Debian system. It is using reverse proxy on apache to redirect requests to apache2 running on any machine which is on Xen server as a Virtual host. I tried to install Drupal on it. Every thing went fine till I pointed my browser to:
http://IP[/url] of LAN where Drupal was installed/drupal
then I see an installation page of Drupal which welcomes me. I click install in English then it can not proceed to connect with database. Database configuration: Your web server does not appear to support any common database types. Check with your hosting provider to see if they offer any databases that Drupal supports.

I have created a database and username for Drupal separately. What should I check to. There is one more error
http://Public IP/some location/
Is showing me contents of Document Root but there is a folder named drupal on it. When I click on it I get error. Not Found. The requested URL /drupal/ was not found on this server. Apache/2.2.9 (Debian) PHP/5.2.6-1+lenny8 with Suhosin-Patch proxy_html/3.0.0 Server at

Debian Configuration :: DHCP For Multiple VLANs

Feb 7, 2016

I'm trying to setup a DHCP server that serves several different VLANs, we have 5 in total. Our network is working correctly, with static IPs, we're able to ping across without any issues.

When I connect my debian box to an interface on VLAN5, statically assign an address in the correct range, it works. Similarly with all other VLANs.

To configure this box as a DHCP, I set one of the ports on the switch as trunk, connect that to the debian box to allow all VLAN traffic to reach my debian box.

I setup DHCP following the steps on [URL] ....

Then I configured different VLANs by following the steps on [URL] .....

However, with the vlans setup, I am unable to ping anything. This is essentially what I did.

Code: Select allSet the port on the switch to trunk with 802.1 encapsulation
disable eth0
vconfig add eth0 5 # to add vlan 5
ifconfig eth0.5 192.168.5.254 netmask 255.255.255.0 up
vconfig add eth0 5 # to add vlan 10
ifconfig eth0.5 192.168.10.254 netmask 255.255.255.0 up

[Code] ....

I do not know why I am unable to get any connectivity through my VLAN interfaces.

Debian Configuration :: DHCP And The Desktop Responsiveness?

I am connected to a network using any interface (eth0, eth1, or wlan0) that if my ip address was given out (dhcp) that my desktop responsiveness gets worse. Specifically the mouse has a sort of "sticky" feeling. I mean by that that I'm moving the physical mouse and the cursor is getting stuck here or there on the screen. It is extremely annoying. Here is my config file:

Debian Configuration :: Host Name Not Broadcast To DHCP

I have setup a few machines within my house. The Debian Squeeze machines do not provide a host name in the DHCP client list on my router. Strangely, my Ubuntu, Android, and Blackberry machines do show host names. I have noticed the same behavior when wirelessly tethering my Debian laptop to my Android phone (which also uses DHCP). Is there something I need to enable to have the name show up on the router?
