Installation and Upgrades / Re: Can't login on server after upgrade on 3.2

« on: December 14, 2013, 10:04:46 pm »

Hello half_life,

Unfortunately I don't agree on most of what you wrote.

I don't think that Zentyal is an OS at all.  It is a simple website used for administering a system &/or a cluster.

Correct me if I'm wrong: 3.0 & 3.2 are both managing Ubuntu 12.04 LTS systems (to some extents we could say alternative desktops too)...

And regarding the famous patch tuesdays, yes, some of it crashed workstations (i.e. MS13-036 bulletin) and the maintainer pulled it out (so acknowledging the issue).

Even a simple update check (not even an update) from the same company crashed multiple servers (i.e. last 29th of february).  If you recall it right, parts of their cloud went down.  Again, the company behind it admitted the error, appologised and fixed it.

A certificate expiring 2013 february 29th... 


All that just to say that, yes, an update (or worst, just checking for updates) badly planned, regardless of the maintainer behind the solution, can turn a nice day into a nightmare.

To me, it is all related to a bad QA (and/or bad practices). 

And to get back to the subject, 3.2 is said "stable".  Stable = production ready. 

My opinion, again;
If a maintainer is providing an update script, that script should also make sure be safe to use. If there is a problem, it should roll back right away and output a log file containing the problem(s) so the system administrators can work on it.

Best,

Marc

Hey all!

this does happen in community supported software

Let me fix that typo for you...
This does happen in community supported any softwares - including licenced (i.e. RHEL) or proprietary software (i.e. Windows).  But this tend to be less and less frequent in the FOSS world since more and more people/companies are contributing to fix bugs.

I'm pretty sure that a lot of you have already done a Patch tuesday & unpatch thursday job 

My 2 pennies;
Zentyal is lacking of log monitoring while updating systems...

Few hours to code an init/update/shutdown script and bam!  You'll end up having a more robust, fault tolerant, auto-scale up/down, hybrid/multi-hosting provider cloud solution that let you revert/update/adapt code/configuration almost automatically.

I ended up with a third place in a hackathon few weeks ago using that kind of lazy approach 

I would add to this (I might also be wrong on that part): The eBox phoenix reborn into Zentyal when the project crossed the chasm...
eBox was at first doing it's QA through the community.  But thing evolved and the community went from a lot of great hackers (eBox) to a more consumer, less talented hackers user base (Zentyal).

And for the closing statement (back to the initial subject):
A good QA process is the key to success!

Thanks for reading

Best!

Hello ap1821,

This HowTo should get you happy:
http://trac.zentyal.org/wiki/Documentation/Community/HowTo/ImportUsersInBulk

And to give you a little bit more, I'm mostly using exec in order to perform shell cmd.

i.e.

Code: [Select]

<?php
// Will echo the Apache user
echo exec('whoami');
?>
Happy hacking

Hello ifti,

You may either go the vhost way, the htaccess way, the header way (if it is a PHP application) or the html refresh way.

Many possibilities

But in all cases, it isn't related to your first/original topic question.

Best,

Marcus

Bonjour link,

Pour répondre à ta dernière question;
Il t'est possible de consulter les fichiers de configurations d'Apache2 sous:
Par défaut:

Code: [Select]

/etc/apache2/apache2.conf
vhosts:

Code: [Select]

/etc/apache2/sites-available/

Dans le doute, n'hésite pas à poster tes fichiers de configuration ici.

Bonne journée

Bonjour Alexbix,

avec ce processeur, crois tu que je peux avoir de bonnes performances

Le choix du processeur dépendra des services que tu désires installer ainsi que la charge dont tu t'attends à recevoir.  Mais bon, le processeur mentionné devrait être suffisant pour le peut de services dont tu as mentionné et satisfaisant pour une vingtaine d'utilisateurs.  Et encore là, cela va dépendre de leurs besoins.

est ce que je peux faire un hotspot wifi (portail captif) ?

Tout dépendant du type de portail captif...  Si tu désires offrir un accès Internet à des visiteurs sans devoir trop investir en temps, Chillispot sur DD-WRT serait un bon choix.  Si tu désires simplement offrir un accès Internet aux membres du personnel, Zentyal sera un bon choix.

Pour les dernières questions, je ne suis pas certain...

En espérant t'avoir éclairer.

Bonjour raber,

Bienvenu sur le forum!

Il est également possible d'installer le serveur depuis une copie originale d'Ubuntu Server (12.04 LTS).  Par la suite, il ne reste qu'à ajouter les dépôts officiels de Zentyal et d'installer le GUI via Aptitude.

Voici les étapes:

Code: [Select]

sudo apt-get install -y python-software-properties

Code: [Select]

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 10E239FF

Code: [Select]

wget -q http://keys.zentyal.org/zentyal-3.2-archive.asc -O- | sudo apt-key add -

Code: [Select]

sudo add-apt-repository ppa:zentyal/3.2

Code: [Select]

sudo apt-get update

Code: [Select]

sudo apt-get install zentyal

Bonne chance!

Installation and Upgrades / Re: RAID

« on: October 04, 2013, 05:43:52 pm »

Hello,

RAID 1&10 are always great!

But, for better performance and enhanced security, I'm usually mounting /tmp and /var/lock in TMPFS.  This is my little trick to overcome some "regular" problems (i.e. keeping DDoS or slashdot effects at bay)

Actually, any temp & not-so-important data should be stored on TMPFS (my opinion)

Hello YAdrien,

Welcome to Zentyal Community!

Are you able to start a X11 session ?

i.e.
1) login using SSH (ssh -X user@ip.of.your.zentyal)
2) start firefox (on the remote host)
3) point firefox to https://localhost:<your zentyal port>

Your problem could be related to few possibilities...

Hello christian,

You are right - my bad.  I just checked in "private browsing" and I wasn't able to see his hostname & IP.

zentyal.nsb.local - does this exist on internet ?

Nope    That is why I'm pointing it as "very bad"

Some other solution would be using the smarthost feature...

Thanks for your input and help - always much apreciated !

Hello aspangilinan,

@ Christian;
You looked at the wrong server...  His hostname is zentyal.nsb.local and not the one that you looked at.

Back to the point;
1) SMTP banner (zentyal.nsb.local) doesn't match the PTR (very bad)
2) SPF is missing (minor)
3) Your IP is currently listed @ APEWS since 2008-04-27 (minor)

Also, I would strongly suggest you to install "DenyHosts" since your SSH port is open

So, what you can do about it (we all love solutions);
1) Change your hostname for the same thing that your PTR is showing
2) Create a SPF entry allowing your IP to send email from your domain
3) Visit APEWS and get unlisted (you may also contact your ISP for that matter)

APEWS website: http://www.apews.org/

** Just doing the first point should fix most of your delivery issues.

Best,

Marcus
