Installation and Upgrades / Re: DHCP
« on: October 20, 2010, 05:03:46 pm »
You may want to read the following post
The server will send a NAK EXCEPT in the following scenarios:-

1. Requested address from possibly the same subnet but not in the address pool of the server:-

This can be the failover scenario in which 2 DHCP servers are serving the same subnet so that when one goes down, the other should not NAK to clients which got an IP from the first server.

Samba sharing can be tricky. Most people forget that Linux is not Windows, even when it tries to fake it.
People that use Windows Server have a plethora of permissions and ACL combinations that are hard, if not impossible, to mimic in Linux. It is very common for people to get into trouble when they try to force a Linux system to replicate the exact behavior of a Windows one.
Having said that, it would be useful if you pinpointed the problem focusing on one particular folder/file where you experience these issues.
Is this problem occurring on all shares, on some of the old shares, or on any new share?
It would be helpful to post the permissions as they are reported in the shell with "ls -al" for each folder from the samba root to the one where you are having problems. Including smb.conf would also be important.
If you try to use chmod, it is very likely that you will need to do it with "sudo chmod" to have administration rights on any object.
It might be important to post the contents in "/etc/fstab" for that particular drive, to see which flags are in effect.
I can't think of anything else right now. I am not an expert by any means, but I have also been bitten by these sort of errors, and the solution was to simplify the structure and permissions.

Thanks for your feedback.
The "community" edition is priced at 0€, but then, you will also have to run your own tests before rolling any changes into your client's systems, right? Because Zentyal will not do that for you. (I still do not understand the rationale behind their release policy: they claim that 2.0 is a stable release, but it is proven that it is not). If I sell a product to a customer, I need some confidence that it will work for a reasonable period of time.
I am testing the systems with the same method you are following: one item at a time and validating each step. In 2.0 I have already identified 2 bugs: one related to non-ASCII characters in the Certificate Authority and another one with the Mail Filter module (apparently, the module fails to update the LDAP database).
Again, I will not test every possible combination, but in a small office you would expect: controlled file sharing, email (with some antispam system) and VPN for secure remote access. This base functionality works for me out of the box in 1.4 and not in 2.0.
That's why I am asking other Zentyal users what's their experience in the real world.

News and Announcements / Re: Zentyal server Release Policy published!
« on: October 19, 2010, 02:56:20 pm »
The last paragraph in the Release Policy states
The Zentyal Development Team offers three years of support for the stable Zentyal versions. This means that since the publication of a stable Zentyal version, support for all security issues as well as commercial support and subscription services will be granted for this version during the next three years. After this time period, the stable version reaches its "end of life" date and becomes unsupported.
Does it apply to 1.4.2, which is a stable version, or only to 2.0 and onwards?
You will have a yearly stable release, each one independently supported for 3 years. Correct?

Thanks for this post. It helped me set up the ftp server in no time.

I think that, as long as the functionality you need is there, you should be safe.
After all, the underlying OS is supported for 5 years, according to this Right?

I have been testing Zentyal 2.0 unsuccessfully. The process always started with a clean installation, followed by an update and upgrade of Linux and Zentyal components. The I gradually added a new component and tested it.
After a few trials It failed on me with the Mailfilter component (didn't receive emails, no warnings in logs, nothing) and now it fails with the VPN.
I have repeated this process about 5 times in Virtualbox.
So, I decided to do the same with EBox 1.4-2, and it worked right out of the box. All the components that were my minimum requirements were functional.
I guess, that 1.4 is the stable version, while 2.0 represents a testing version.
I would like to ask all of you what's your experience with these versions. Which version are you using in production environmentes: 1.4 or 2.0?
Have you installed 2.0 with all the lates components and is it working without a glitch?
I would appreciate your feedback on this.

I couldn't help but notice that in your tests you use "test" as the shared secret, but your dd-wrt screenshot has "test-secret" in it.
Has it anything to do with anything?

Installation and Upgrades / Re: Zentyal 2.0 and DNS in LAN
« on: October 16, 2010, 04:03:04 pm »
Could you clarify it a little bit more?
Is your router a dedicated computer you have installed, or is it a commercial router, such as a Netgear, Cisco, etc?
Have you troubleshooted your DNS config with tools like nslookup or dig?

Actually, my post was written after several installs/reinstalls and I was truly fed up with the system already.
I didn't step into the Groupware/Zafara thing yet. I was more in the bare smtp/imap thing.
During this process, I installed the Mail module and created a DynDns account pointing to my network.
My router is forwarding the ports properly. I tested the Webmail module as well, sending and receiving emails between my VirtualBox Zentyal system and my Gmail account.
Then I installed Mailfilter (which pulled the Antivirus module) and email stopped working.
I could send email out to Gmail, but I could not receive it from Gmail.
I looked into all the conceivable Log files but I didn't get a clue as to what was causing that behaviour.
I uninstalled and reinstalled Mailfilter and Antivirus about 3 times, playing with different settings.
Perhaps I will try another setup in another VirtualBox machine later on.
Right now I am still too pissed off with this software to get anything right.

By the way, I have checked out your site and your offers are quite good. Nice machines. If you get Zentyal working there and you can support it for a long time, it must be a great business.
I was looking to follow the same route (that's why I was testing it), but I am having my doubts.

Installation and Upgrades / Re: Software or Hardware RAID
« on: October 16, 2010, 03:10:55 am »
Quick comment here: having a RAID as the system drive doesn't seem a good idea. The purpose of a RAID system is to withstand a drive failure. But ... if one of the drives fails, you would need a system to rebuild it, right? Now, if your system is on that RAID, you can't repair it if it fails ...
The FutureTechSys configuration seems quite reasonable: a small drive for the system and a large storage for data (be it a single drive or a RAID). If the RAID needs to be rebuilt, you still have the system drive.

Well, I have spent a few more hours on this issue.
I have purged Mailfilter and Antivirus. Updated the system from a SSH prompt and reinstalled each package in turn and following the logs. This is the only way of knowing what's going on.

Installing ebox-antivirus leaves me with clamav and lack of signatures for the viruses. I had to manually run "clamav-daemon start". Weird.

Installing ebox-mailfilter causes the same error with LDAP (again it fails to create the users "ham" and "spam")

2010/10/15 15:39:29 DEBUG> EBox::UsersAndGroups::addUser - Missing argument: Password
2010/10/15 15:39:29 ERROR> EBox::Sudo::_rootError - root command /usr/share/ebox-mailfilter/ebox-mailfilter-ldap update failed.
Error output: Missing argument: Password
Command output: .
Exit value: 255

I am also finding other issues in the logs, like:

2010/10/15 17:19:21 WARN> EBox::Mail::_getDovecotAntispamPluginConf - More than one module offers configuration for dovecot plugin. We will take the first one

And I keep receiving an email in /var/mail/root with the message:

run-parts: failed to exec /etc/cron.hourly/freshclam: Exec format error
run-parts: /etc/cron.hourly/freshclam exited with return code 1

Now, this cron entry is supposed to call freshclam to update the virus signatures. I check that file and I see that it is an empty file:

root@zentyal:~# ls -al /etc/cron.hourly/freshclam
-rwxr-xr-x 1 root root 0 2010-10-15 15:21 /etc/cron.hourly/freshclam

No wonder it can't execute it.

So, now, with the mailfilter module installed, I can send email out but I cannot receive email.
Amavis seems to log everything into syslog, but I have found no relevant messages.

I have ended deleting the MailFilter component but now I can't receive any email.
So ... I give up (at least for now).
I was looking for my company to become a partner with Zentyal, but I don't trust this software.

It must be a Jersey thing ... :-)

I downloaded the ISO a few days ago.
Still, I updated the system until no more System Updates were available.
Zentyal Components were updated to the latest versions (2.0.x) as well.
I monitored each component installation and no errors were displayed on the GUI.

I have been adding a few components at a time, enabling and testing them gradually.
In the past I have set up servers with Linux Ubuntu, with Postfix email, Amavis, Spamassassin, LDAP, Samba, etc. all on my own, so I am not a total newbie.
Then I tried this package (when it was in version 1.3-1.4) because it seemed very convenient. eBox/Zentyal doesn't seem to like anyone interfering with the system, so I gave up on installing packages directly on a Ubuntu server, and now I want to follow Zentyal's procedures entirely.

I want to be able to trust a Zentyal installation and to be able to administer it remotely with confidence. I am not betting my business reputation on a half baked product, that can fail you at any time with odd errors. Am I supposed to mess with their Perl scripts?

In the meantime, if someone could shed a light on this error, it would be nice.

I installed a VirtualBox machine from the Zentyal 2.0 ISO.
I have been testing all the modules one by one.
I have configured the Mail and Webmail modules and I can successfully receive email.
However, enabling the MailFilter module breaks the email system.
I have disabled and reenabled the MailFilter module and here are the relevant bits in the /var/log/ebox/ebox.log file:

2010/10/15 00:19:56 INFO> EBox::Module::Base::save - Restarting service for module: logs

2010/10/15 00:37:02 INFO> EBox::ServiceManager::__ANON__ - File /etc/amavis/conf.d/amavisd.conf does not exist. So we won't compute its digest

In the MailFilter module I had checked the options to have a ham and a spam account, but they do not exist in the LDAP database. I assume it is related somehow.

Still on the administration page, I click on Save Changes.
The ebox.log displays the following lines:

And the administration page shows the following error:
Some modules reported error when saving changes . More information on the logs in /var/log/ebox/
The following modules failed while saving their changes, their state is unknown: mailfilter

These sort of "misterious" errors and the lack of proper solutions in these forums scare me away from this eBox/Zentyal thing.

The errors I am reporting here have been reported by other users in the past but I failed to find a solution for them.
Someone else experiencing the same problem?
What is the best path? Ignoring the Mailfilter module?
