Installation and Upgrades / Re: Zentyal 7 fresh installation problem

« on: July 19, 2022, 03:51:41 pm »

Hi,

Zentyal does not use Netplan, in fact, it uninstalls it during the installation.

According to the first image, your Zentyal server does not have any IP configured, that is why you cannot use the Webadmin either SSH. You can configure a network IP using the command ip and then, login to the Webadmin and configure the network module.

* An example of the IP command: https://linuxize.com/post/linux-ip-command/

Basically, if you install Zentyal but you do not configure the network module, as soon as you reboot the server, it won't be able to get from a DHCP server or configure an IP address because the network configuration file has not been configured yet.

after configuring with ip command its work after continue the installation form web then stuck again, reboot the server then ip missing again what happen for this, any guide i can use why this keep happening i event cannot continue installation on web.

Hi,

How did you configure the network interfaces? Did you check your network configuration status? You can run the following command to check it:

Code: [Select]

ip addr show

this is capture from ip add

  Could you explain me your system topology extensely (a detailed graphic would be appreciated) and the problem one more time? I'm re-reading the topic and I fear I don't have understood rightly your issue. 

Really, to keep a process  reading the dhcp leases in order to execute an script based on the samba-tool doesn't seems to me the better of the fixes. (Besides, Zentyal webadmin doesn't reflects these DNS records created by samba-tool)
However, the more I think about it the more i'm convinced that you should search the solution on the Ebox API.
(Obviously this task is undistinguisable of fixing the Zentyal dynamic dns bug) O_o

In relation with the possibility of using another DNS server, be conscious that the Zentyal Domain Controller has to be the DNS server (Samba4 manages the DNS server itself) so, you don't have to install another DNS server, ( it solves anything ). Simply you have to configure DDNS on the BIND9 of the Zentyal Samba4 implementation and the Zentyal DHCP without breaking them (nor Zentyal)
Remember that you have to modify the needed parameters on the Zentyal stubs. (read this: https://doc.zentyal.org/es/appendix-c.html#stubs )
I would like to try this this week end. I'll tell you about it!
Cheers!

topology

i just want user from wireless can join domain, hence from you statement by default if we configure zentyal as domain control it must be include dns in zentyal it self..?

but dhcp server from zentyal to simple, if we have multiple ip address with multiple class it can be done using multiple nic it is correct ...?


Thanks and Regards

(Do you really need Domain controller?)

###NB: Zentyal webadmin doesn't shows the new records introduced throught samba-tool.!!!!

Ok, I was supposing all the services were provided by Zentyal. So, I have wasted lot of time, I'm sorry. As you are using Zentyal as Domain Controller DNS records should have being automatically configured.

However, if your DNS clients aren't joined to the domain you can configure the DNS records for these machines this way:

Code: [Select]

#Create a samba user on the webadmin and add him to the Domain Admins group (in my case 'admindc' with password 'admindc')
#Add admindc to the DnsAdmins group:
sudo samba-tool group addmembers DnsAdmins admindc

I have done this really basic script:

Code: [Select]

while IFS=" " read -r name ip
        do
                echo " Creating DNS record for ${name} host with ip ${ip}";
                samba-tool dns add 192.168.1.43 zentyal-domain.lan ${name} A ${ip} --username=admindc --password=admindc &&
                        echo " A record successfully created";


        done< "hosts-list.csv"

 where host-list.csv is this:

Code: [Select]

windows1 192.168.2.2
windows2 192.168.2.3
windows3 192.168.2.4
windows4 192.168.2.5
windows5 192.168.2.6
windows6 192.168.2.7

Locate the script and the host-list.csv on the same folder and run the script. (Remember you have to grant -x permissions to the script)

As a result you have this:

Code: [Select]

root@curso:~# samba-tool dns query localhost zentyal-domain.lan @ ALL --user=admindc --password=admindc

Do it for the needed records and modify it for other kind of records that you'll need

Cheers!

Hi Doncamilo,

really appreciated your reply and help, but its look like more complicated.
how about if i create dedicated server for dns only hence, zentyal only for domain controller because we want to manage client laptop with GPO that's way we need zentyal for domain controller for manage using RSAT


Regards

Hi! 

It means that a process that should be done automatically have to be done manually.

However I have to remember you the basis because I don't understand how do you uses Zentyal. O_o

Zentyal DHCP server only can be configured to serve IP's on the "internal network interfaces". So, if you have an only interface which is configured as "external" in order to grant internet access to the Zentyal server you don't be able to use DHCP assignations on this network.

I think that to buy a cheap network interface is the better of the solutions.


Other case, please show me your domain topology in order to give you a more accurated response.

Cheers!

Hi Doncamilo,

we have mikrotik router act as DHCP server with multiple subnet our topology is
ISP ==> Mikrotik ==> Switch L3 ==> ESX Server (including zentyal)

hence,  zentyal for domain controller only with dns, my problem is if i not add manually ip client to zentyal dns they cannot browsing because query refused.

is there any solution for this to add segment ip without add manually one by one...
for example if we use bind9 for dns we can accept multiple subnet for any segment, so dns can serve multiple ip with one interface.

Hi!
The problem is that dynamic DNS is bugged. The right way to add automatically the ip's and host names is enable the DHCP module whit his dynamic DNS feature enabled. But, this doesn't run at all (I have readed some time ago that it will be fixed on Zentyal 6.1 in some moment around november 2019)
Other solutions are to do a little exercice of bash or perl scripting... Give me some time in order to try it.
Cheers!

i want to achieve with one interface can deliver multiple ip address with dhcp and dns server this is cannot be done because of bugged this is correct ....?


Thanks

Hi Don,

so if use one interface it can be done.
i use static ip for this and zetyal configure for domain controller and dns.

i just add hostname client and ip address like you mentioned before just like that ..?
so how to add more then 1 client because use your method add one by one..

Thanks

If I have understanded rightly your problem you have a Zentyal server with three network interfaces: an external interface and two internal interfaces. Isn't it?

Usually Zentyal introduces automatically the IP of the Zentyal interfaces. Check the Domain IP Addresses record and the hostnames  (see this picture: https://doc.zentyal.org/en/_images/dns-04-domains.png)

If some of the IP of the internal interfaces hasn't being included, do it yourself (click on the correspondants gear icons)

Read this: https://doc.zentyal.org/en/dns.html#configuration-of-an-authoritative-dns-server-with-zentyal

(If you enables the transparent DNS option you'll not have to configure DNS on the client machines)

Cheers!

hi Don,

sorry i only have one interface for this just for internal only but we have multiple ip address for employer,
so i want to configure zentyal as domain control and dns server is this possibly doing this with one interface...?

Thanks for reply.

Hi ALL,

i setup zentyal as domain controller and dns, but we have another ip for device zentyal using 192.168.x.x ip and another device using 172.172.x.x how we configure dns zentyal so 172.172 can query or use zentyal dns.

because client ip 172.172.x.x try nslookup got refused


really need advice.

Thanks
