Installation and Upgrades / [Solved] NTP spamming the syslog; permission denied.
« on: November 18, 2012, 06:45:53 am »
I've just installed my first Zentyal 3.0 server at a client's shop. It wasn't easy but in the end all is running.
There are some minor issues however, starting with this ntp issue:
I made sure every instance of the NTP service was killed before restarting, but I cannot get rid of it. Reboot does not solve it.
Any tips would be welcome.
Cheers.

Installation and Upgrades / Latest update Network Configurator borks server
« on: November 10, 2012, 10:06:22 pm »
This morning I noticed a component update to the network configurator (Zentyal version 2.2.7) and installed it.
After saving the changes, there was no internet anymore, not on the server and not on the clients.
I restarted the server and it was obvious the firewall and network were not starting, as observed from the list of modules.
There are 4 network cards in the server, 2 external and two internal. The connection type is PPPoE.
At this moment I have started the network and firewall from the terminal and at least it enables me to post this message, but the network is still down for other clients on the network.
Please review this update because something went terribly wrong, the server is unusable at the moment. If you need more info please let me know.
Edit: The boot log, observe network and firewall not starting:
This is a piece of the Zentyal log file when booting:
Part of the installation log, the culprit is Zentyal Network module 2.2.9
Cheers.

Installation and Upgrades / [Partially solved] Zentyal 2.2 Samba configuration.
« on: September 24, 2012, 06:31:41 am »
I'm a little confused ![Smiley :)](https://forum.zentyal.org/Smileys/default/smiley.gif)
running Zentyal with Samba as a non-PDC, goal is to do basic filesharing.
On the first page, "general settings" the "domain name" parameter has to be specified.
My organization has a domain name, it's like "mycomputernetwork.com" that allows presence on the web.
So, logically I filled out that domain name in the Samba "general" configuration page. And that is where the trouble starts.
Looking in the file /var/log/samba/nmbd, this error appears:
Investigating further, it became clear that the "domain name" cannot contain more than 15 characters, hence the error.
Looking at the Zentyal documentation, it is stated:
So my question would be:
- Do I need to change my existing domain name to something less than 15 characters, or
- Is the domain name field actually referring to the "workgroup" name since it is used on the local network?
I find this a little bit confusing.
Cheers.

Dutch / Voorlopig programma van de Zentyal Summit 2012.
« on: September 11, 2012, 12:59:01 pm »
Onderstaand persbericht ter info.
5 september 2012
(Zaragoza, Spanje)
Zentyal S.L, ontwikkelaar van de Zentyal Linux Small Business Server, heeft vandaag het voorlopige programma voor de Zentyal Summit 2012 aangekondigd, dat zal plaatsvinden op 4 en 5 oktober in Zaragoza, Spanje. Gebaseerd op de ervaring en feedback van de extreem populaire summit van vorig jaar, gaat het programma dit jaar verder met het verstrekken van cutting-edge content voor de behoeften van IT-ondersteuning aan service providers en IT-beheerders geïnteresseerd in Linux-gebaseerde IT-infrastructuur management oplossingen voor kleine en middelgrote bedrijven (MKB/KMO).
De summit begint op donderdag 4 oktober met een toespraak van Tom Henriksson, Partner bij Open Ocean Capital. Tijdens zijn toespraak "De sleutel om categorie-winnende open source bedrijven te herkennen en te toetsen" geeft hij inzicht in wat er nodig is voor open source start-ups om succesvol te worden. Open Oceaan, de eerste grote eigenaar van MySQL AB, is een toonaangevend vroeg-stadium venture capital bedrijf, met nadruk op Europese start-ups waar het gaat om de inzet van een gebruikers gemeenschap van het open source business model.
Tijdens de twee dagen van het evenement, geven open source software fabrikanten zoals Canonical, ontwikkelaar van het populaire Ubuntu, besturingssysteem, en Zarafa, ontwikkelaar van het Zarafa e-mail-en samenwerkingsplatform, samen met Zentyal een reeks van zowel commerciële presentaties als technische workshops. Het zal mogelijk zijn om te leren over desktop en server migratie naar Linux-gebaseerde systemen, hoe de hardware te kiezen of om de infrastructuur te integreren met user-level toepassingen, of welke voordelen Samba 4 en single-sign-on hebben voor het IT-infrastructuur management in het MKB, om er maar een paar te noemen.
Naast advies van fabrikanten, zullen de deelnemers ook de kans krijgen om te leren hoe IT-ondersteuning en service providers, zoals Leucotron, Neodoo of Calat, hun eigen service portefeuilles bouwen op basis van Linux en open source oplossingen. Aan de andere kant, zal de Community trac, gehouden op vrijdag 5 oktober, inzicht geven in de rol van de gemeenschap achter Zentyal als een open source project en zal het ook de kans geven om ideeën voor te stellen en uit te breiden voor de roadmap van de volgende versie van Zentyal server.
Er hoeft geen inschrijfgeld betaald te worden voor deelname aan het evenement, maar het aantal plaatsen is beperkt, dus een spoedige inschrijving wordt ten zeerste aanbevolen. Zowel het programma als inschrijvingsformulier zijn te vinden op de summit website op: http://summit.zentyal.com.

5 september 2012
(Zaragoza, Spanje)
Zentyal S.L, ontwikkelaar van de Zentyal Linux Small Business Server, heeft vandaag het voorlopige programma voor de Zentyal Summit 2012 aangekondigd, dat zal plaatsvinden op 4 en 5 oktober in Zaragoza, Spanje. Gebaseerd op de ervaring en feedback van de extreem populaire summit van vorig jaar, gaat het programma dit jaar verder met het verstrekken van cutting-edge content voor de behoeften van IT-ondersteuning aan service providers en IT-beheerders geïnteresseerd in Linux-gebaseerde IT-infrastructuur management oplossingen voor kleine en middelgrote bedrijven (MKB/KMO).
De summit begint op donderdag 4 oktober met een toespraak van Tom Henriksson, Partner bij Open Ocean Capital. Tijdens zijn toespraak "De sleutel om categorie-winnende open source bedrijven te herkennen en te toetsen" geeft hij inzicht in wat er nodig is voor open source start-ups om succesvol te worden. Open Oceaan, de eerste grote eigenaar van MySQL AB, is een toonaangevend vroeg-stadium venture capital bedrijf, met nadruk op Europese start-ups waar het gaat om de inzet van een gebruikers gemeenschap van het open source business model.
Tijdens de twee dagen van het evenement, geven open source software fabrikanten zoals Canonical, ontwikkelaar van het populaire Ubuntu, besturingssysteem, en Zarafa, ontwikkelaar van het Zarafa e-mail-en samenwerkingsplatform, samen met Zentyal een reeks van zowel commerciële presentaties als technische workshops. Het zal mogelijk zijn om te leren over desktop en server migratie naar Linux-gebaseerde systemen, hoe de hardware te kiezen of om de infrastructuur te integreren met user-level toepassingen, of welke voordelen Samba 4 en single-sign-on hebben voor het IT-infrastructuur management in het MKB, om er maar een paar te noemen.
Naast advies van fabrikanten, zullen de deelnemers ook de kans krijgen om te leren hoe IT-ondersteuning en service providers, zoals Leucotron, Neodoo of Calat, hun eigen service portefeuilles bouwen op basis van Linux en open source oplossingen. Aan de andere kant, zal de Community trac, gehouden op vrijdag 5 oktober, inzicht geven in de rol van de gemeenschap achter Zentyal als een open source project en zal het ook de kans geven om ideeën voor te stellen en uit te breiden voor de roadmap van de volgende versie van Zentyal server.
Er hoeft geen inschrijfgeld betaald te worden voor deelname aan het evenement, maar het aantal plaatsen is beperkt, dus een spoedige inschrijving wordt ten zeerste aanbevolen. Zowel het programma als inschrijvingsformulier zijn te vinden op de summit website op: http://summit.zentyal.com.

Installation and Upgrades / [Solved] How to disable ipv6 in Zentyal?
« on: June 29, 2012, 01:20:30 pm »
The syslog is filled with these messages:
After checking with my provider, it appears that both my adsl modem and the provider's network are not ipv6 capable.
It should be easy to disable ipv6 in bind9, by adding -4 to /etc/default/bind9
This is how it looks now:
Restarted bind from the console and all was well...at least that's how it should be.
The errors just keep coming while ipv6 is disabled, why is bind still trying to resolve ipv6 when there is a specific directive set
to use only ipv4?
I read about adding some lines to sysctl.conf:
But before something gets borked, can someone push me in the right direction?
Cheers.

Installation and Upgrades / [Solved] Unable to connect to Zentyal Cloud, but admin page shows connected.
« on: June 06, 2012, 04:04:39 am »
There are reports of similar issues on the forum, but at the moment I don't know what is the status of this issue.
Zentyal Cloud is still not working, it shows connected on the admin page but the VPN log states:
It's best to add some images to this post.
I've been unsubscribing and subscribing my server over and over again, sometimes it works for two days but it always drops offline after a while.
The cloud module was updated some days ago, and now it always shows connected but it does not reflect the real connection status.

Still hoping for a solution, some day.

Dutch / Richtlijnen voor het aanmaken van berichten of onderwerpen.
« on: May 26, 2012, 01:50:32 pm »
Deze instructies komen oorspronkelijk uit het Engelse forumdeel, voor sommigen is het misschien wat makkelijker te volgen in het Nederlands.
Met dank aan Oceanwatcher.
Welkom bij de Nederlandse Zentyal gemeenschap!
Iedereen helpt hier op vrijwillige basis, we antwoorden als we iets weten over het onderwerp en als de tijd het toelaat. Wellicht kun je zelf ook actief helpen.
Om eventuele problemen snel op te kunnen lossen, zijn er enkele dingen die je kunt doen voordat je hier een bericht post.
Als je eenmaal besluit om te posten, zijn er een aantal gegevens die je zowiezo dient te vermelden.
De zoekfunctie.
--------------
Allereerst: Zoeken. Het is goed mogelijk dat je niet de enige bent met het probleem, dus maak gebruik van de zoekfunctie. Soms kan het lastig zijn om de juiste woorden te vinden (niet iedereen spreekt Engels of Spaans), maar probeer het gewoon. Je kunt dan in je bericht vermelden waar je naar gezocht hebt.
Upgraden.
----------
Zorg ervoor dat je installatie up to date is. De ontwikkelaars van Zentyal werken elke dag aan de software en eventuele bugs worden zo snel mogelijk verholpen.
Upgraden doe je door deze commando's op de commandline in te geven:
Posten.
--------
Mocht het euvel niet verholpen zijn, maak dan een bericht met een korte omschrijving van het probleem als onderwerp.
Vermijd kreten zoals "Help!" of "Ik heb een probleem...". Gebruik geen voorvoegsels, behalve dan [OPGELOST] als de kwestie opgelost is. Hou het kort en bondig.
Zentyal versie.
--------------
Vermeld altijd de Zentyal versie waarmee je werkt, evenals de versie van het Ubuntu besturingssysteem.
De huidige stabiele versie is Zentyal 2.2, de beta versie 2.3 wordt later dit jaar Zentyal 3.0.
Het is mogelijk dat de beta versie nog enkele bugs heeft, hou daar rekening mee als je een keuze moet maken tussen Zentyal 2.2 of Zentyal 2.3.
Functie en situatie.
------------------
Is het een productie server (wordt actief gebruikt) of is het een configuratie die enkel voor testen gebuikt wordt?
Is Zentyal op een PC geïnstalleerd, of draait het in een virtuele machine zoals VirtualBox enz.?
Hoe is de Zentyal machine op het Internet aangesloten?
Is deze server de gateway naar het internet voor je netwerk?
Versies van de Zentyal modules.
------------------------------
Er zijn nog een paar andere dingen die je ook kunt vermelden.
Geef dit commando op de commandline in en plak het resultaat in het bericht:
Debug mode.
-----------
Je kunt Zentyal ook in "debug mode" laten draaien, als het probleem dan opnieuw optreedt kun je de logs bij je bericht voegen zodat we er naar kunnen kijken.
Zo doe je dit: (start een console via SSH of geef deze commandos in een console op de server):
Verander "debug = no" in "debug = yes" en sla het bestand op.
Probeer om het probleem weer op te laten treden. Herhaal de procedure die Zentyal liet crashen of stoppen. Vergeet niet om deze procedure ook in je bericht te vermelden.
We hebben dit nodig om zelf ook te kunnen zien waar het fout gaat.
Post je zentyal.log
------------------
Je kunt het bestand hier vinden:
Ga naar de website:
Het onderwerp als "Opgelost" betitelen.
----------------------------------------
Als het probleem opgelost is kun je de titel van het onderwerp veranderen en er [Opgelost] voor zetten.
Je doet dit door naar het eerste bericht in het onderwerp te gaan en op de knop "Modify" te klikken. Je kunt dan de titel veranderen.
Dit helpt iedereen om juist die onderwerpen te vinden waar mogelijk reeds een oplossing voor het probleem gegeven is.
In het geval dat er nog geen [Opgelost] voor staat, kan dit betekenen dat het probleem nog niet is opgelost en dat verdere hulp nodig is.

Installation and Upgrades / [Solved] Tracert - Slow reverse lookup on hops in LAN.
« on: April 19, 2012, 12:48:47 pm »
It's been a while, Zentyal is working great. I have a minor issue with tracert and perhaps other members might have noticed it?
When doing a trace route from a PC on the local network, the hops that are part of our internal network take a long time to resolve.
From reading on the net, I understand it is a problem with reverse lookup. Doing a nslookup yields:
This weird behaviour started only a few days ago. Pinging internal (or external) IP's directly is no problem.
If I use the switch /d for the tracert command, all is well (obviously)
The OS is windows XP, DNS server IP is the Zentyal box.
I also tried setting the DNS server to Google DNS, the result is the same.
Executing tracert from the zentyal gui itself is OK, so the issue might be some recent update.
I'm open to suggestions, but most of all I would like to know why it never happened before?
Cheers.

Installation and Upgrades / IPSec service not starting due to "orphaned pluto.pid".
« on: January 18, 2012, 11:56:50 am »
Recently, when rebooting the Zentyal server, I noticed the IPSec service is not starting. It can't be started from the admin page.
As a result, the server can not connect to Zentyal cloud.
To resolve this issue, it's necessary to open a terminal as root and type:
And the resulting message states that there was an "orphaned pluto.pid" and it was removed.
Typing:
The annoying part of it all is that the cloud subscription does not work anymore and the server has to be "unsubscribed" and after that subscribed again.
This procedure has to be repeated at every reboot.
I read about the valid subdomain name and I'm sure it is valid, no weird characters in the name.
Is there anything that can be done to solve this behavior?
Cheers.

Installation and Upgrades / [SOLVED] Squid proxy crashed and stops working.
« on: January 01, 2012, 12:19:39 am »
Squid proxy is behaving very strange lately. I included the log, perhaps someone has seen these lines?
It seems that url_rewriter requests are the cause of the crash. But I don't know if the "CACHEMGR: <unknown>@127.0.0.1 requesting" lines have something to do with it.
I have shut down the Apache webserver and Zoneminder but nevertheless the messages are still appearing and squid might be crashing again any moment.

Installation and Upgrades / Zentyal Cloud - Basic subscription problem.

My server disconnected from Zentyal Cloud about one week ago, without any reason.
The VPN log showed that it couldn't connect to the public IP address (timed out). So I pinged the public IP and got the echo.
Searching the relevant topics I found the advice to remove the server's basic subscription and to subscribe the server again.
Then I got this error:
The Zentyal log showed this:
I have some problem with the certificate that is non-existent, so it seems. How can I resolve this problem?
Cheers.
Edit:
Amazing, I actually repaired something myself as opposed to borking my server every now and then.
After the error, what I did was removing the server subscription from Zentyal itself, > save modules. OK.
Then I subscribed the server again, got the message "Subscription data retrieved successfully".
Save modules and check cloud status > Working!

Installation and Upgrades / Adding exceptions to the Adzapper script.
« on: November 24, 2011, 07:34:19 pm »
Better to tackle this issue right now before someone else is looking all over...
Today one of my users complained about not being able to see the photos on some website. He said that somewhere else the photos were loading just fine.
After visiting this site:
Opening the foto gallery yielded the same result.
I knew instantly that it was the Adzapper playing up, but adding the sites address to the exception list (Dansguardian) didn't solve anything.
After poking around in my server I found the script here:
A little down the list there are a few lines starting with "PASS", those are the sites that will NOT be zapped so I just maintained the same format and added
amarillasinternet to the list.
After restarting the proxy all was well.
I don't know if this will "stick" after an update. In that case it could be helpful to know how we can create static exception lists.
You have to take care with the cache, sometimes you need to clear the browser cache to have all the stuff come up again.
Hope this eventually saves people from searching all over.
Cheers.

Installation and Upgrades / [Partially solved] Error> Could not get lock for service: firewal
« on: November 19, 2011, 10:05:26 am »
I the process of finishing my new Zentyal 2.2 setup I came across several little anoyances.
After changing something in Zentyal, when saving, the firewall takes quite a long time to save.
It just sits there for a minute before all other stuff saves.
This is the corresponding error in the logs:
Perhaps I've got an idea how this happened. Wanting to block Facebook, I created a network object with al of Facebook IP's inside.
There were about 4 ranges and those made up for really a lot of IP's.
When putting the block rule in the firewall with destination the Facebook IP's, it probably was too much because saving took nearly 15 minutes
and even the Internet connection went down.
Seeing this was an impossible situation, I quickly removed the block rule from the firewall.
Saving the configuration went a lot faster, but still not as fast as before the incident.
The question is, could there be some left overs in the firewall config? Does Zentyal really delete the rules or is it like "disabled"?
How can I troubleshoot this situation?
Cheers.

Installation and Upgrades / Squid: WARNING: All url_rewriter processes are busy.
« on: November 19, 2011, 09:38:48 am »
In the Squid logs this message appears:
I looked in squid.conf.mas and at line 31 it states:
How can I define the urlRewriteProgram and subsequently, get rid of the errors?
Cheers.
Add some extra info:
I found this on the web, it seems that on Linux the package can be compiled (or should I say "build") with these options
This is annoying because everytime it happens, it stalls pages loading and the delay is noticeable.
I suspect that our Zentyal Squid wasn't compiled with this option. I would really like some feedback from the devs, I'm willing to open a bugreport in the tracker if it's necessary.

Installation and Upgrades / Error creating new users.
« on: November 17, 2011, 10:35:21 pm »
The last issue to report for today in 2.2 is a Samba bug on a 2.2 fresh install.
When creating new users, click on "add" and some error pops ups that it can't create the directories. Result: User dir is created but no profile!
As a workaround we can create the directory structure by hand, after that users can be created without errors.
Create folder
In that folder create 3 subfolders:
Create users as planned.
Cheers.
