Installation and Upgrades / DNS problems
« on: February 23, 2012, 03:15:13 pm »
I have set up a domain in DNS (mydom.local) and added the server at its IP address (zentsrv, 192.168.1.2), and created a dynamic domain (wks.mydom.local) that the workstations join (set up in DHCP).
This is the same as http://doc.zentyal.org/en/dns.html in the image under 'Configuration of an authoritative DNS server with Zentyal'.
The workstation can ping 192.168.1.2 OK, but not zentsrv.mydom.local
Is there a problem with the configuration?
Thanks

Installation and Upgrades / Re: Static hosts on Dynamic DNS.. quick questions
« on: February 22, 2012, 04:00:42 pm »
Is this topic still alive? Has there been any progress?
I'm hoping that the latest ZY 2.2-1 has incorporated the features above.
I have added an object with a member (server-name, Server's IP address) to the Fixed Addresses in DHCP.
I have opted for dynamic DNS and this works fine. However my dynamic domain does not include the server.
Have I missed something?
... I give up!
I don't think it's possible to have on my network:
workstation1.mydom.local (added dynamicaly to DNS)
and
server1.mydom.local (static)
I'll try a new post bout using subdomains instead...

Installation and Upgrades / Re: DNS problem: browse to server by name not IP address
« on: February 22, 2012, 10:37:18 am »
I have just discovered that this very issue is discussed (but I'm not sure if resolved) in:
http://forum.zentyal.org/index.php?topic=5002.0
The issue is about wanting static dns entries as well as dynamic entries for the same domain.
The last post was Mar 2011 so the fix may already be in ZY 2.2-1
I'll check this out & post there...

I'm a bit clearer what the problem is. I do not want to individually configure workstations - I just want DHCP and DDNS to do the job.
I think you're right about Win7 workstations using NETBIOS. That leaves the Linux machines with the problem.
I have a dynamic domain mydom.local. I have checked its config files on the server and they do indeed get updated with workstations' details.
On the linux workstation I tried this:
myadmin@mycomp-OptiPlex-745:~$ host -l mydom.local
mydom.local name server ns.mydom.local.
INVISIBLE-PC.mydom.local has address 192.168.1.12
mycomp-OptiPlex-745.mydom.local has address 192.168.1.11
ns.mydom.local has address 127.0.0.1
This seems to indicate that the DNS setup for the domain needs the server added (zentsrv.mydom.local at 192.168.1.2). However I can't add hosts to a dynamic domain...!
There must be a simple solution other than to add this to all workstation's hosts files:
192.168.1.2 zentsrv.mydom.local

Installation and Upgrades / Re: Domain confusion...
« on: February 09, 2012, 08:19:15 am »
Thanks very much Bogdan - I think I've had this confusion for years!
I'll suggest to MS that they refer to an AD domain as say an 'AD Area'
Pure conjecture below:
================
It does raise the question as to what a Windows computer does on the network when joining an 'AD domain' - I have just found this on the MS site that answers this: the DNS server holds records that allow the joining machine to locate the DC and I assume that when you put an 'AD domain' name into File Sharing in ZY it adds the following record to the ZY server's DNS records: ehe _ldap._tcp.dc._msdcs.DNSDomainNameservice (SRV) resource record

DNS requirements for joining an Active Directory domain
Updated: January 21, 2005
Applies To: Windows Server 2003, Windows Server 2003 R2, Windows Server 2003 with SP1, Windows Server 2003 with SP2
DNS requirements for joining an Active Directory domain
Active Directory uses Domain Name System (DNS) to locate domain controllers, enabling computers joining the network to obtain a domain controller's IP address, and then begin the process of network authentication.
Computers joining an Active Directory domain must satisfy the following three DNS requirements:
The computer must be configured with the IP address of a preferred DNS server.
The _ldap._tcp.dc._msdcs.DNSDomainNameservice (SRV) resource record must exist in DNS.
The address (A) resource record for the DNS name of the domain controllers specified in the data field of the _ldap._tcp.dc._msdcs.DNSDomainName SRV resource record must exist in DNS.
Configuring a computer’s preferred DNS server
You must configure the computer with the static IP address of a preferred DNS server manually or assign the IP address of a preferred DNS server using Dynamic Host Configuration Protocol (DHCP).
For more information, see To configure a computer's preferred DNS server.
Configuring the required DNS resource records
Computers joining an Active Directory domain need the following resource records in DNS to locate a domain controller:
_ldap._tcp.dc._msdcs. DNSDomainName SRV resource record, which identifies the name of the domain controller that hosts the Active Directory domain.
DNSDomainName is the DNS name of the Active Directory domain the computer is attempting to join.
A corresponding address (A) resource record that identifies the IP address for the domain controller listed in the _ldap._tcp.dc._msdcs.DNSDomainName SRV resource record.
For more information, see To verify the DNS resource records needed to join an Active Directory domain using nslookup; Configure TCP/IP to use DNS.

Installation and Upgrades / [Solved] Domain confusion...
« on: February 08, 2012, 11:02:50 am »
I'm sure I'm being stupid here - but I do not see why there is a domain name entry in File Sharing - General Settings (ZENTYAL-DOMAIN - which I did not choose during installation), and a different domain name that I have set up in the DNS module (dynamic domain mydom.local) - should these not be one and the same thing? I am not sure what the role of the one in File Sharing is other than that it must be chosen when joining a Win machine to the domain.

Installation and Upgrades / Re: Need to turn off Mail filter to get Webmail working
« on: February 01, 2012, 07:00:02 pm »
Could be. I'm not sure how to check whether a DNS server is operating correctly. I assume as long as the client knows the DNS server's IP address (getting this via DHCP) it can send a query. I know that the Win 7 machine knows the DNS server address (the ZY server's) using ipconfig. I need to check if the Ubu machine also knows this (but I can't install nslookup or dig as this is in a College & I can't connect to the Internet!).
Maybe I need to add the server's name to the DNS config on the server somehow (and I assume ddns will add the client machines automatically).

Using ZY 2-2.1, Ubuntu 11.10 client:
In webmail the mail sends but is not received (just within the lan between users set up on the ZY server) unless I disable the mail filter on the server. Have I missed something?

« on: February 01, 2012, 06:14:26 pm »
OK thanks - good thought. I'll try this next week. I would have expected that DHCP would have informed the client of this though - and it would be a bit inconvenient on a large network!
In the setup of ZY (see screenshot at http://doc.zentyal.org/en/dhcp.html) I did set Search Domain to Custom and selected my domain 'mydom.local' (that I had previously added in the DNS section)

Installation and Upgrades / DNS problem: browse to server by name not IP address
« on: February 01, 2012, 05:09:09 pm »
I have set up ZY 2-2.1, named the server zentsrv, in DNS added domain mydom.local
In DHCP enabled DDNS etc
From a Windows 7 machine using Windows Explorer I can browse to the server as \\zentsrv and see & access shares. I can also use eg http://zentsrv in IE.
From an Ubuntu 11.10 machine I can do everything as above but must always connect using the server's IP address eg http://192.168.1.2, but would prefer to use http://zentsrv
I must have missed something - is it anything obvious?

Thanks very much vshaulsk! Problem solved.I assumed that having given a domain name during the text setup that would be it...
My notes from 2.0 don't mention having to do this - I must have though I suppose!

Thanks ichat.
Just realised that I can see the ZY Admin GUI from another machine where I can screenshot... Will get back to this next week. Thanks so far.

In 2.0 I could do this, but not in 2.2:
Configuring DHCP, Dynamic DNS Options, Enable - but now the Dynamic Domain combo is disabled so I can't type/select a domain name.
There is a similar problem with the Common Options: the Search domain combo is greyed out.
I can't save the options as ZY correctly says that I haven't made these choices!
Have I missed something? (probably!)
Thanks for any hints...
