DDNS DHCP problem

[morpheus78]

In my named.conf I wrote that :

controls {
        inet 127.0.0.1 port 953
                     allow { 127.0.0.1; 192.168.1.1; } keys { "rndc-key"; };

But that change nothing. I'm sure I have a rights/folder places errors.
I tried a named-checkzone and I have :

root@linux:/etc/bind# named-checkzone db.utopia.net /var/cache/bind/zone/db.utopia.net
/var/cache/bind/zone/db.utopia.net:3: ignoring out-of-zone data (utopia.net)
/var/cache/bind/zone/db.utopia.net:12: ignoring out-of-zone data (linux.utopia.net)
/var/cache/bind/zone/db.utopia.net:13: ignoring out-of-zone data (dc.utopia.net)
zone db.utopia.net/IN: has 0 SOA records
zone db.utopia.net/IN: has no NS records
zone db.utopia.net/IN: not loaded due to errors.

Could you give me the right way where to place the conf files, the zones, and what command use to put the appropriate rights to the folders?

Thank you

You're using named-checkzone incorrectly. You should be using 'named-checkzone utopia.net /var/cache/bind/zone/db.utopia.net' and you'll probably fine it returns without a problem. I'm afraid that I'm running out of ideas to try, and my only suggestion is to try a version of DHCPD that I know works for me: 4.2.3-P2 ftp://ftp.isc.org/isc/dhcp/4.2.3-P2/....2.3-P2.tar.gz
I do recall having problems with the latest version of DHCPD.

The checkzone works fine too, I'll try to uninstall previous dhcpd version and install yours.
I'll let you know, thank you

[morpheus78]

I triyed to install it (1st time I install soft on linux ). I found dhcpd.conf in /usr/local/etc/ but I don't know where to launch the dhcp server ?
The 1st version was installed by synaptic, (4.1.1).
Can you help me?

[Krendoshazin]

I find it's usually sufficient to compile DHCP with:

./configure --prefix=/usr --sysconfdir=/etc

and then

make install

as root. This should put dhcpd.conf in /etc and dhcpd in /usr/sbin.

[morpheus78]

I allready installed it without argument in ./configure.
How do you do to start the daemon?

And I saw that this version include a bind ddns???

-EDIT-

I cleared my VM so I installed your DHCP version with the argument you specified.
I'll try to use the bind used with the DHCP.

[Krendoshazin]

Don't worry about the BIND stuff that it mentions; that's just for DDNS with DHCPD. It doesn't install a new version of BIND. You can start DHCPD by running /usr/sbin/dhcpd as root from the command line. You can worry about the startup script once you know it's all working.

[morpheus78]

I reinstalled all the VM using aptitude, install by myself is hard to configure.
I configured my zones in /etc/bind/zone
I configured named.conf like yours.
I configured dhcpd.conf like yours.

I made a new key and I put the folowing code in named and dhcpd (and in rndc.key):

key "dhcpupdate" {
        algorithm hmac-md5;
        secret "YFvQAeHjqu60dnqOf8BqwA==";
};

I configred my interface eth0 with static 192.168.1.1

----------------------

Now, I need to configure my hosts file no ? (can I see yours?)
And resolv.conf? (can I see yours?)
I don't forget files ?

[morpheus78]

resolv.conf

search utopia.net
nameserver 127.0.0.1

hosts

127.0.0.1       localhost
127.0.1.1       linux.utopia.net        linux
192.168.1.1     linux.utopia.net        linux

# The following lines are desirable for IPv6 capable hosts
#::1     ip6-localhost ip6-loopback
#fe00::0 ip6-localnet
#ff00::0 ip6-mcastprefix
#ff02::1 ip6-allnodes
#ff02::2 ip6-allrouters

host.conf

multi on

checkzone and checkconf ok, no error in syslog when i restart or reload bind9, no error when I restart dhcpd.
With nslookup I cen see linux and 192.168.1.1 in the both (linux and machine-user), but I always got NXDOMAIN for machine-user... and dhcp don't update the zones

My syslog when I restart bind9 :

If DHCPD is trying to update the zones and can't, then it should at least throw out an error about it. Try going over your system logs to see if DHCPD has logged anything; we need to see what DHCPD is doing when it hands out an IP address.

Also, Can you repost named.conf and dhcpd.conf again since you've modified them?

Additionally I noticed that you're using 'auth-nxdomain no;' in named.conf. Be sure to delete that option as you don't require it. I would also recommend moving your zones out of the subnet and get rid of the duplicate utopia.net zone in dhcpd.conf.
