Installation and Upgrades / [SOLVED] Zentyal4.1: DHCP: TFTP/pxelinux.0 ?
« on: December 28, 2015, 01:21:28 pm »
Hello,

I have now Zentyal 4.1 including latest updates; I just wonder if it is possible to migrate our DHCP-Server to Zentyal?
At the moment, we have a different machine serving a single pxelinux.0 TFTP-image for all the clients:

nobody    3078  0.0  0.0  15320  1092 ?        S     2014   6:32 /usr/sbin/dnsmasq --bind-interfaces --interface eth0 --except-interface lo --enable-tftp --tftp-root=/etc/pxeboot --dhcp-boot=/etc/pxeboot/pxelinux.0 --dhcp-range=192.168.0.2,192.168.0.173,168h --log-dhcp

This single command line above handles all quite well.
How to migrate this DHCP/TFTP-functionality away from this "extra-server" to Zentyal?  I cannot find any option in Zentyal 4.1 that allows me to select a TFTP-file to send, when the BIOS of a client needs one?

Hello, World.

I am now trying to update a Zentyal 4.1 machine to 4.2; I repeatedly click on the webinterface on the "Software management" options and its sub-buttons, but no matter what I try, I never get an option to update Zentyal from 4.1 to 4.2.
So as I understand it, the only way to upgrade to Zentyal 4.2 is a fresh install from CD?

I spent many hours of installing and configuring Zentyal 4.1. Are there any options to update to 4.2, and if so, how to do it?

Hello,

I have configured and installed the domain called "companyname.lan" ; but under "DNS-> Domains" I actually have two domains:
a) Companyname.lan ......  ("redcross symbol" no dynamic domain)  (action: you can delete it)
b) zentyal-domain.lan .....  ("green symbol" :   YES , dynamic dom.) (action: you CANNOT delete it - greyed off)

Why cannot I delete zentyal-domain.lan - do I really need it if I only want "companyname.lan" ?

Self-installed duplicity complains about a domain name and host name mismatch:

root@srv01:/root# duplicity /mnt/data1/shares ftp://ba1@192.168.0.230/shares_backup

Fatal Error: Backup source host has changed.
Current hostname: srv01.zentyal-domain.lan
Previous hostname: srv01."companyname".lan

How do I change the hostname back to "companyname.lan" and NOT to "zentyal-domain.lan" ?
Preferably an easy way without deleting all users etc?

The story so far:

We had a Zentyal server 3.5, we upgraded to 4.0. The upgrade seemed to work. Then we upgraded to 4.1. That one made lots of troubles. So we had no other options as to :
* save all mails from /var/vmail into one large TAR file
* save important data from /home/samba/profiles
* reinstall Zentyal 4.1 fresh from CD on the server
* manually add the same (luckily few) users
* re-configure domain, shares, users, fetching external mail for users.
* get back the /var/vmail file with the old user mails. Set ACL rights for the shares properly by hand (using chown, chmod, setfacl)

This worked almost neat so far, with the notable exception that we had to apt-get some packages by hand, otherwise we could not install mail/groupware and openchange server (for full details , see : https://forum.zentyal.org/index.php/topic,26713.0.html )

Anyway, we have an almost neat working Zentyal server now, who properly fetches external mails (totally necessary) and who properly gives out the samba shares and is the master of our windows domain, so people can log on their win7 clients anywhere in the local net.

The only problem is: It only works perfectly for ADMIN USERS, which are in the group "Domain Masters" (if I remember that name correctly).
Normal users, who are just in the (self-added) group "normalusers" or "limitedusers" or "pureemail" have the following problems:

* Login on a Win7 client almost always results in a warning that "you are logged in with a temporary profile".
* Lots of sync problems between the profiles in general
* External mails are not fetched properly.

So if anyone has a clue how to fix these sync problems and "temp profile" problems etc.etc. please let me know. I have the vague feeling it might have to do with insufficient rights or misconfigured rights, but I could be mistaken. Is there any option to edit what rights the normalusers should have?

Hello,

I have installed Zentyal 4.1 - suddenly it works fine, after the xth reinstall. I dont know why.
At the Zentyal install, I added two crypted partitions and they work just fine, the main "/" directory is crypted as well as another mounted partition from sda2 to /mnt/data.
The bootloader (?) asks me for the 2 passwords whilst booting and it simply works. Great.
But: I want to add another harddrive,  /dev/sdb, it contains one large crypted partition, /dev/sdb1 , and I want to modify the bootloader so that it also asks me for the password of this (third) crypted partition.
It is a LUKS crypted partition, but it was made with a former, older Zentyal.

I somehow could not recognize it during the installation process, and the installer always said he wanted to format that drive, and I dont want to format it, I want to use it normally.

So how do I add that old drive/partition (/dev/sdb1, crypted) to the existing bootloader?

i have a bug that is repeatably happening.
After installing Zentyal 4.1 and adding users, and domains, these users cannot log in in their freshly added win7-domain.
They get an error: "the security database on this server does not contain an account for this workstation trust"
(german error: "Die Sicherheitsdatenbank auf dem Server enthält kein Computerkonto für diese Arbeitsstationsvertrauensstellung" (what a word!  :o ) )

FIX found:

* service samba stop
* service samba-ad-dc stop
* service bind9 stop    (may be useless tho, but helped anyway)
* samba-tool domain provision -> now just press return all the time to re-enter your stuff
* service bind9 start
* service samba-ad-dc start
* service samba start

I hope this helps anyone.

I can login to the windows7 workstation with my Zentyal account now, but despite this, there is a large tendency to use a temporary profile. I will now remove from my Win7-client the registry keys from the old zentyal accounts and the temporary dirs.

Hello,
I have a little DNS quirk. I can ping "zentyal" from a client in the same local net, but I cannot ping "zentyal.mydomain.lan". If I try to, I immidately get "host not found".
Once I tried to "service restart bind9" on the zentyal server and it helped, but now I try to do this again, but it does not work anymore. The ping to "zentyal.mydomain.lan" still fails.
Any help?
Zentyal version is 4.1.
Edit: Oh, I just got a mail saying "Samba is not yet provisioned". Hm. Maybe its a clue. So, what to do?

Hello,

I just installed a fresh Zentyal 4.1 server. I configured network correctly,  I can reach internet.
I also can reach the server config at https://server:8443
But I cannot install some software.

In the software center, I am offered to install:
Mail and Groupware    4.1.3    
OpenChange Server    4.1.3

but when I tick them on, I get errors:

Openchange server install says:

"Einige Pakete konnten nicht installiert werden. Das kann bedeuten, dass
Sie eine unmögliche Situation angefordert haben oder, wenn Sie die
Unstable-Distribution verwenden, dass einige erforderliche Pakete noch
nicht erstellt wurden oder Incoming noch nicht verlassen haben.
Die folgenden Informationen helfen Ihnen vielleicht, die Situation zu lösen:

Die folgenden Pakete haben unerfüllte Abhängigkeiten:
zentyal-openchange : Hängt ab von: openchangeserver (>= 3:2.4-zentyal3) soll aber nicht installiert werden"

Similarly, I get the error - when installing openchangeserver:

"Einige Pakete konnten nicht installiert werden. Das kann bedeuten, dass
Sie eine unmögliche Situation angefordert haben oder, wenn Sie die
Unstable-Distribution verwenden, dass einige erforderliche Pakete noch
nicht erstellt wurden oder Incoming noch nicht verlassen haben.
Die folgenden Informationen helfen Ihnen vielleicht, die Situation zu lösen:

Die folgenden Pakete haben unerfüllte Abhängigkeiten:
zentyal-mail : Hängt ab von: zentyal-openchange soll aber nicht installiert werden"

So the error is in both cases, zentyal-openchange should not be installed. Why not? How can I get past the error and install some mail, including mail fetching from external mails, for users?

Hi,

I updated everything to Zentyal 3.5.2 recently, which was a bit of a hassle, a few days ago, and now two more modules are recommended to being updated: Mail module and user corner.
But I don't know exactly what the update is going to do, and I fear troubles.
So I won't do the update until I know what will happen - will anything be removed, etc.?
Please, let me know what the update is doing.

Hi,

I upgraded from Zentyal 3.3 to 3.4 and immidely to 3.5.2 today; now, Zentyal does not fetch external mails, which is totally essential to me.

I noticed that I got some mails with errors:

So what to do to get fetching of external mail to work again?

German / email password nicht geändert?
« on: May 30, 2014, 03:37:40 pm »
Folgende Konfiguration:

* Jeder User hat einen lokalen Account: user1, user2, user@lokaldomain.lan
* Kerberos/Samba rennt
* Eine lokale Domäne lokaldomain.lan existiert
Wir melden uns auf der lokalen Domäne am Win-Client per Kerberos an, erstellen ein Thunderbird-Konto, folgendermaßen:
* user1@lokaldomain.lan
---> der User1 holt externe mails von GMX.DE ab
---> landen am lokalen Zentyal-Server, welcher sie abholt
---> zum *ANTWORTEN* existiert im Thunderbird eine Zweitidentität : "userX@externe-domain.COM" der wird nur zum VERSENDEN verwendet, ist aber die Standardidentität des users "userX@lokaledomain.LAN" !

Empfangen tut also der lokale ".lan" Benutzer, ANTWORTEN tut dessen Zweitidentität und GESPEICHERT wird das gesendete auf der Kerberos-Domäne dank servergespeicherte Profile.

Das funktioniert soweit, so gut.

Jetzt hat aber der lokale Kerberos-Benutzer "user1" sein password von "xxxxxxxxxxxxxxx"   auf "yyyyyyyyyyyyyyy" geändert.
Folge: Mozilla Thunderbird regt sich auf, daß er keine Verbindung zum Zentyal bekommt.

Also: Test : "Alle gespeicherten Passwörter löschen" ---> es stellt sich heraus, daß zum Abholen der Mails noch immer das alte Kerberos-Password "xxxxxxxxxx" notwendig ist.

Was nun?

Wie kriege ich Zentyal dazu, das neue Password zum Mail-Abholen zu verwenden?

Hello,
I have mounted some drive (/dev/sdc1) at /mnt/data1.
I want Zentyal to include this directory, /mnt/data1, for backupping.
Unfortunately, I saw that the backup system only backs up files from anything else but from extra mounted drives.
Is there anything that I can do about it ?


29
Hi,
I tried the webinterface to issue a scheduled backup at 18:00 today, and I found out that it would not backup the data from the external drive /mnt/data1 to the FTP-backup server (192.168.x.y:/home/Zentyal)
What *was* backed up, were the other directories I selected.
Any help ?

Under "domain/group policy objects", I added a group policy objeects called "loginscripts".
However, it is empty.
Then I decided to delete that empty object. It is not possible.....
So what to do?
