Directory and Authentication / Zentyal 4.1 issue with file name between Windows and OSX (mangled names)

« on: September 09, 2016, 10:26:12 am »

Hello,

"Back in the days of DOS and Windows 3.1, every filename was limited to eight upper-case characters, followed by a dot, and three more uppercase characters. This was known as the 8.3 format"

In the past I had an issue with a NAS system:
basically, in a mixed environment Windows/MAC sometimes file renamed by Windows were seen as 8.3 alphanumeric characters by MAC.
After many firmware upgrade the developers put an option in the NAS to disable the "mangled file" option in samba. With a simple tick you can individually add to every share the option  "mangled names = No"

Few days ago a customer called me told me that if someone modify a file from Windows in their Zentyal server, He can not open the file with his MAC because the name of the file changes in 8.3 alphanumeric characters (with .TMP extension). From this MAC he see the file in that way, meanwhile Windows users see the files with the correct name
They have a server with  Zentyal 4.1  (Ubuntu 14.04.3 LTS GNU/Linux 3.13.0-68-generic x86_64)
In my opinion this is the same issue I had in the past with the NAS.

Is this synonymous the customer is describing is related with "mangled file"?
And if this is the case how can I add the option "mangled names = No" to the samba configuration?

I tried to add the option to /etc/samba/shares.conf but after a reboot obviously it disappear
Any body knows how to solve this?

Thanks a lot!

Other modules / DNS cache TTL time on the DNS service.

« on: May 10, 2016, 05:38:38 pm »

Hello,
I have Zentyal 3.4 as domain server and DNS server for my internal LAN
I would like to reduce the DNS cache TTL time on the Bind service.
As I work as web designer I often need to ask external domain administrators to change the DNS resolution
At that point from my local area I can not reach the remote site because my zentyal DNS cache is still caching the old IP
How can I reduce the TTL time?

my /etc/bind file looks like this:

include "/etc/bind/named.conf.options";
include "/etc/bind/keys";

// prime the server with knowledge of the root servers
zone "." {
        type hint;
        file "/etc/bind/db.root";
};

// be authoritative for the localhost forward and reverse zones, and for
// broadcast zones as per RFC 1912

zone "localhost" {
        type master;
        file "/etc/bind/db.local";
};

zone "127.in-addr.arpa" {
        type master;
        file "/etc/bind/db.127";
};

zone "0.in-addr.arpa" {
        type master;
        file "/etc/bind/db.0";
};

zone "255.in-addr.arpa" {
        type master;
        file "/etc/bind/db.255";
};

include "/etc/bind/named.conf.local";

« on: October 31, 2014, 04:41:16 pm »

Hello Everybody, Konnchiwa minna-san,

I am looking for a way to enable roaming profiles in a remote Additional Domain Controller.
At the moment there is only a check box in the primary Domain Controller.

For example is there a way to modify the script smb.conf.mas?

Many many many thanks

« on: June 12, 2014, 11:37:07 am »

Hello,

Is there a correct procedure or a best practice in order to remove a Secondary dead Zentyal 3.4 DC from a Zentyal 3.4 PDC?

Do I need to use "active directory sites and services" from Microsoft tools, also do I need to manually remove DNS entries?

Thanks

Installation and Upgrades / Rsync best practice to synchronize two zentyal server or a NAS with Zentyal

« on: April 10, 2014, 08:09:29 pm »

Hello,

We have this two scenarios:
1)
A NAS   as primary file server.
On the Zentyal server there is a share called BACKUP.
We need to rsync push all files and folders from the NAS to the Backup folder available on the zentyal server..
Is it possible to run this configuration?
The Rsync NAS configuration module it ask for the IP of remote server (that is the Zential IP) and user and password.
With a normal zentyal user it seems not working.
Is there a different user we need to set up?

2)
Two Zentyal servers one is "Primary domain controller" and the second one is an "additional domain controller"
On the primary domain we have samba with many shares full of files and folders
Every night we need to copy all of this files in the additional domain controller via rsync
Here we have the same question, how to set up this rsync configuration scenario, the best practice to do this task
 
Thanks a million !

Installation and Upgrades / Antivirus behavior in Samba

« on: April 10, 2014, 07:41:07 pm »

Hello,
Zentyal 3.3 as VM used as Office server with many samba shares full of file and folders.
Another VM Windows 2008 R2 server with installed SyncBack Pro as backup software.
On zentyal the antivirus is up and running checking all the shares

have this scenario:
every night SyncBack Pro is configured to copy all file and folder from Zentyal to a NAS
The relative vfs objects = scannedonly module in samba generates for each file scanned by the antivirus some small files with name .scanned: files, .failed: files and .virus
as you can see here: https://www.samba.org/samba/docs/man/manpages/vfs_scannedonly.8.html

When SyncBack will run and read files in the source shares will see thousand of small files with tilde symbol like  ~$myfile.someting, (instead of .scanned .failed .virus)  etc., also many regular files will be blocked because the antivirus didn't scan them yet, also these file can not be deleted from users,etc., etc., and other related issues, that are quite annoying in a samba environment with hundreds of thousands of files

At the moment the only good solution was to disable the antivirus module and delete all the files .scanned .failed .virus with a linux command.

We need some suggestions how to fix this issue, we prefer to have the antivirus, but we need use SyncBack Pro as backup software as for customer request.

Thank you

Installation and Upgrades / Issue adding a new clean zentyal installation to a Windows 2012 AD

« on: February 28, 2014, 05:18:12 pm »

Hi,
I am new on this forum, hello everybody  !

Well I am new to Zentyal as well, I am testing this distribution in order to evaluate it's use for one customer that need a Linux Samba server, inside a Windows 2012 AD forest. In the future I'd like to implement this distribution to customer that need samba and other useful service in a mixed environment Win/linux or just for Linux environment.

But as soon as I start to study this distribution I encountered a problem:

I have just installed Zentyal on a Proxmox environment with Zentyal as OFFICE infrastructure, choose internal network card and standalone server with default hostname. zentyal and domain zentyal-domain.lan ( I have adopted this option because the one to add zentyal to an existing domain was giving me an error message stating that the domain should be zentyal domain and not the one installed on Windows 2012).

I need to join Zentyal to a Windows 2012 domain named test.local the server name is srv2012.test.local.
Well, when I choose in the server role "additional domain controller" and i fill-in all the fields but something goes wrong.
I followed tutorials and video guide, but all refer to old Zentyal version or are not detailed.

Please is there a clear and deep procedure example to show how to accomplish the join of an Win2012 AD?

thank you very much
