Hi!
Is this normal, that the Zentyal Certificate is getting revoked, when the server get started?
The Certificate should be valid nearly 10 years: Zentyal    Valid    2024-02-15 06:18:12
But ...

Installation and Upgrades / Cannot access VirtualHost SSL Page
« on: April 07, 2014, 10:44:02 am »
Hi!
I cannot access the HTTPS Page of my VirtualHost. I have enabled the SSL support (Allow SSL) at the VirtualHost and I enabled the HTTPS Listening Port (443).

If I use http://myhost.x.y I see my VHost Page, but if I try https://myhost.x.y I only see the default SSL Page of the Webserver.

the apache config for my virtualhost looks like

<VirtualHost *:62080>
  ServerAdmin webmaster@xxx.home.lan
  ServerName myhost.x.y:80
  DocumentRoot /srv/www/myhost.x.y
  [..]
</VirtualHost>

<IfModule mod_ssl.c>
  <VirtualHost *:62443>
    ServerAdmin webmaster@xxx.home.lan
    ServerName myhost.x.y:443
    DocumentRoot /srv/www/myhost.x.y
    [..] 
  </VirtualHost>
</IfModule>


[..] means some more lines

German / s4sync und samba verbrauchen 100% CPU
« on: January 09, 2014, 04:53:28 pm »
Hallo!
Ich bin dabei einen kleine Heimserver aufzubauen, wobei Zentyal 3.3 auf Ubuntu 12.04 in einer VM mit 2GB läuft. Nachdem der Server fast 24h läuft, freue ich mich über jedes eingesparte Watt im Betrieb.

Jetzt habe ich gemerkt, dass das Skript s4sync und samba alle 30 Sekunden 105% der CPU verbrauchen (lt top), und dadurch der Stromverbrauch für ~10 Sekunden von ~ 18 - 20 Watt auf über 30 Watt klettert, danach fällt er wieder ab, CPU Verbrauch sinkt wieder auf 2 - 5%.

Ist das ein normales Verhalten, oder auf eine schwache CPU zurück zuführen? Hab jetzt 2 Lösungen ausgearbeitet, würde gerne wissen was für Nachteile zu erwarten sind.

  • s4sync wartet statt der 30 Sekunden, 240 Sekunden, bis es wieder weiter macht.
  • s4sync habe ich so abgeändert, das in den foreach Schleifen jeweils 5 ms Pause gemacht wird, dadurch fällt die Gesamtbelastung auf ~ 65 - 75%. Was der Unterschied in Watt mach, muss ich erst schauen.
  • s4sync habe ich so abgeändert, das in den foreach Schleifen jeweils 20 ms Pause gemacht wird, dadurch fällt die Gesamtbelastung auf ~ 40 - 50%. Was der Unterschied in Watt mach, muss ich erst schauen.

ad. 1) Mir ist klar, dass ich bei Änderungen bis zu 4 Minuten warten muss, bis Samba darauf reagiert.
ad. 2 + 3) Mir ist klar, dass bei einer großen Anzahl an Sync Objekten, der Prozess dadurch länger braucht, hab aber nur max. 10 User + Gruppen und ist für mich eigentlich nicht relevant.

Host: Ubuntu 12.04
Gast: KVM, Zentyal 3.3, Ubuntu 12.04
CPU: Intel(R) Celeron(R) CPU 1037U @ 1.80GHz
RAM: 4 GB

Sodale Verbrauch mal nachgeschaut, gemessen mit Voltcraft Energy Check 3000 von Conrad, also kein Hightech Produkt ;-)
ad. 2) von 23 - 24 W
ad. 3) von 22 - 22,6 W

Hi!
It took me 2 days to find a solution, to access a Samba Share with Owncloud (Apache). First I tried to change permissions and the Samba config (/usr/shares/zentyal/stubs/samba/smb.mas):
  • forcing group (www-data)
  • forcing user (www-data)
  • create mask 0777
  • force create mode 0777
  • and so on
But the permission of the files and directory always where 0770, and with the line "force user" always an error occured. The permissions of a share automatic changes to root:Administrators. It was annoying ...
So I tried another way ... accessing the samba shares with www-data by mounting each share. It is not working out of the box, but it is working for me ;-) If I want to access the share "Public" with Owncloud, I had to do following steps ...

Creating Directory
Create Directory /mnt/shares/Public

fstab
Adding following line to fstab (/etc/fstab)
//127.0.0.1/Public /mnt/shares/Public cifs user=username,passwd=password,uid=www-data,gid=www-data,file_mode=0770,dir_mode=0770 0 0

Mounting
sudo mount -a
now the directory /mnt/shares/Public should have www-data:www-data and permission 0770.

Owncloud
Changing the data directory of owncloud to the Samba Share is not a good idea, because owncloud has a file cache and do not recognize files added through a samba share. But you can add an app called "External storage Support", and at the Administration area, you can add the samba share like ...
  • Folder name: @Public
  • External Storage: local
  • Configuration: /mnt/shares/Public
  • Applicable: user1, user2, user3

Problem: Mounting at startup is not working
I do not know, why exactly ubuntu/fstab cannot add the shares at startup, but if you add a file called for example S99mount_samba_share in /etc/rc2.d with

#!/bin/sh
mount -a

your shares are mounted at startup.

Hi!
I cannot install OpenChange Server. Following Error occured:

The following packages have unmet dependencies:
Zentyal-openchange: Depends on: sogo-openchange (> = 2.1.0-zentyal6) but it is not installable
Depends on: sope4.9-GDL1-mysql (> = 4.9-zentyal1) but it is not installable

I tried a clean installation with zentyal-all, the same error occured.

System: Ubuntu 12.04 Server

After 1. Login I saw the page, where I could choose the packages to install.
There I saw and could choose any package.

But when I click on [info] at office and after that close this info, the package selection is still invisible and i cannot choose any more packages or can install it.

* Add Service to Firewall
1.) Goto Firewall -> Packet Filter and select "Filtering rules from internal networks to Zentyal"
2.) Add Service Zarafa-Groupware

* Bind Address 0.0.0.0
1.) Open Terminal on server (or connect with Putty to your server)
2.) sudo nano /usr/share/ebox/stubs/zarafa/server.cfg.mas
3.) locate line server_bind=127.0.0.1
4.) change to: server_bind=0.0.0.0

* Install Zarafa licensed Server
1.) Try: sudo apt-get install zarafa-licensed

if this is not working:
!!Please take a look to Post #4!!

1.) Download the correct Zarafa Version at http://download.zarafa.com/community/final/
2.) 2010-12: http://download.zarafa.com/community/final/6.40/6.40.3-23410/zcp-6.40.3-23410-ubuntu-10.04-i386-free.tgz

goto Directory /etc/init.d/ -> mv zarafa-licensed-dpkg-new zarafa-licensed
goto Directory /etc/zarafa/  -> mv licensed.cfg.dpkg-new licensed.cfg
goto Directory /etc/defaults/ -> mv zarafa-licensed-dpkg-new zarafa-licensed
6.) Start Zarafa License Server: /etc/init.d/zarafa-licensed start

*Configure Outlook
Sorry, this is in german, but I have no english version of outlook
   1.) Download & Install http://download.zarafa.com/community/final/6.40/6.40.4-24200/windows/zarafaclient.msi
   2.) Extras → Email-Konten → Neues E-Mail Konto hinzufügen

   6.) Port: 236 or 237 for https
   7.) Username: Username on Ebox
   8.) Password: Password on Ebox
   9.)  Connectiontype (??): Online

* To-Do
1.) Zarafa-Licensed-Server will not start at startup, so I have to add "zarafa-licensed start" to the start script
2.) updates are broken

Regards
Michael
