Hello,

I stumble on that error few times.  Generally a simple reboot will fix this problem.

In other words, I do suspect an update that didn't properly restart the service.

Have you rebooted since this error showed up ?

Installation and Upgrades / Re: Optimize for low-spec machine?

« on: April 24, 2011, 02:16:21 pm »

Hello iGadget,

There is 2 Apache instances because the first one is for Zentyal's GUI and the second one is for your webserver.

In order to stop your webserver and not the Zentyal's GUI:
Zentyal ­­ ­­» Module Status » Web Server (and uncheck it)

What else do I need to start / restart to get this back working?

You may restart your Zentyal installation by running this command line in a terminal:

Code: [Select]

sudo /etc/init.d/ebox restart

Installation and Upgrades / Re: Remote Desktop For Zentyal !

« on: April 19, 2011, 07:06:01 pm »

Hello,

I'm using X11 forwarding capabilities in order to work on the server (if I ever need to be "local").

It is quite simple to do...

From an Ubuntu desktop:
Replace
<admin> with your username
<your Zentyal IP> with your server IP or domain name

Code: [Select]

ssh -X -C <admin>@<your zentyal IP>
* The -X is the X11 Forwarding and the -C is for compression *

After that you only have to fire up Firefox or any other software and done - your now working "local" without even getting close to your server!

Hope it will help...

Best,

Marcus

Hello,

Looks like you have more than one issue with your server...

To restart Zentyal from command line:

Code: [Select]

/etc/init.d/ebox restart
As a side note;
LAN will not get access to the WWW if the HTTP proxy is down

You should also take a look at your hard drive usage to see if there is any partition that is full.

Good luck

Hello sixstone,

I wasn't very far - just busy


So there goes my results:

Code: [Select]

Failed to start dhcpd :

dhcpd self-test failed. Please fix the config file.
The error was:
Internet Systems Consortium DHCP Server V3.1.3
Copyright 2004-2009 Internet Systems Consortium.
All rights reserved.
For info, please visit https://www.isc.org/software/dhcp/
/etc/dhcp3/dhcpd.conf line 125: expecting left brace.
     host Marc workstation
                             ^
Configuration file errors encountered -- exiting

Lines around 125 in /etc/dhcp3/dhcpd.conf :

           }
     group {
                   

     host Marc workstation {
    hardware ethernet so:me:bo:gu:sm:ac;
  fixed-address 192.168.2.80;
                         

                          }
           }
After removing the space between Marc and workstation (making it MarcWorkstation), DHCP server restarted without any issue.

So the problem is right there...

Heading for the bugtracker and opening a new one...

Thanks for your advice

Installation and Upgrades / Re: Webserver

« on: April 05, 2011, 08:07:05 pm »

Hello ctek,

You only have to create 2 virtual host and configure your domains DNS* to point your webserver.

Once done, simply drop your files in the apropriate folders on your server.

*When configured properly, the DNS propagation can take up to 72hrs (it takes generaly less then 6 hours to propagate but still, 72hrs is the "official" answer).

As a side note,
- each websites folders will be under /srv/www/<domain name> path on your server.
- You may have to configure your firewall to accept connections on port 80 and 443 of your external interface

Have a nice day!

Best,

Marcus

Installation and Upgrades / [SOLVED][BUG] DHCP + Static IP issue

« on: April 04, 2011, 05:01:16 pm »

Hello,
I'm experiencing some difficulties with the new DHCP system.

From time to time (most of time), when adding a static IP to the list, DHCP server fails to restart.  Restarting it from the admin gives me a:
"The module was restarted correctly."

But in facts, it does not restart correctly.  

There goes the error reported by the DHCP server when trying to restart it:

Code: [Select]

dhcpd self-test failed. Please fix the config file.
The error was:
Internet Systems Consortium DHCP Server V3.1.3
Copyright 2004-2009 Internet Systems Consortium.
All rights reserved.
For info, please visit https://www.isc.org/software/dhcp/
/etc/dhcp3/dhcpd.conf line 59: expecting left brace.
    some static name
                             ^
Configuration file errors encountered -- exiting
Ok,
I must admit that I'm a bit short in time so I didn't test every possibilities in order to identify where this error comes from.

So it can be:
a) A space in "some static name"
b) The MAC is already listed in the DHCP server list.

** This is the current "workaround" that I'm using in order to restart the DHCP server:
1) Check the error log
2) Remove the problematic static IP from the list
3) Restart the DHCP server

Any help for figuring this one out would be greatly appreciated
otherwise
I'll post the solution/problem source when I'll find it

Thanks for reading

Best,

Marcus

Hello pmp6nl,

Your Motorola is a modem+router.  You'll need to first make the port forwarding there.

I found a small howto for your device:

Installation and Upgrades / Re: Zentyal 2.0.1 Port Forward problems

« on: March 31, 2011, 02:23:16 pm »

Hello,
I had the same bad experience.  It end up being a code 14 (14 inches in front of the screen).

So things to make sure when setting up the port forward:
1) Service added
2) Firewall External -> Zentyal open on the specified port
3) Firewall External -> Internal open on the specified port
4) Port forwarding MUST use the proper(external) network interface card **That was my error
5) Saving changes

And everything worked as expected

Best,

Installation and Upgrades / [Zarafa Indexer] High CPU load

« on: February 20, 2011, 05:47:47 pm »

Hello,
I faced a problem last week. 

I decided to do a stress test on my email server.

There goes the spec of the Zentyal 2.0 box:
Kernel and CPU    :            Linux 2.6.32-28-generic on x86_64
Processor information :     AMD Athlon(tm) 64 X2 Dual Core Processor 5400+, 2 cores
RAM:                                 2GB DDR2 800MHz
Hard Drives :                     RAID 10 w/ 4X1.0TB (SATA-II, WD Green)

Test
Total emails :                   35,000
Sending from :                 2 servers
Email type:                      text
Attachment :                    no


Send/Receive took about 10 minutes over a 8Mbps WiFi and 32Mbps CPL networks (real speed).

CPU and RAM on the Zarafa box was all fine until Zarafa's indexer kicked in >>  CPU jumped to a load of 16.0.  I had to put a stop to it after an hour of non sens CPU load so I restarted the indexer.  Everything was fine for something like 5 minutes then the load came back.

The indexer problem came from 2 obvious facts:
1) Much email came in simultaneously
2) Zarafa indexer was set to 5 minutes

The second observation is the most important one.  Not having the time to index everything within the default configuration, Zarafa was queuing indexing requests, bringing the load to the roof.

In order to fix the problem and avoid any problems related with a spam flood, I had to modify the configuration of the indexer.  This way, Zarafa indexer was able to finish the indexing process before the next one and keeping the CPU load to an acceptable level.

This is how I change the indexer from 5 minutes to 30 minutes:

In a terminal as root user

Code: (terminal) [Select]

# cd / && find . -name 'indexer.cf*' | xargs perl -pi -e 's/index_interval = 5/index_interval = 30/g' && zarafa-indexer restart
Explaining this command
It will look for 2 files on the server:
1) /etc/zarafa/indexer.cfg
2) /usr/share/ebox/stubs/zarafa/indexer.cfg.mas

Then, it will change the lines

Code: [Select]

index_interval = 5for

Code: [Select]

index_interval = 30
And at last, it will restart the Zarafa indexer service.


Note that you may have to repeat this after a Zentyal update (if zarafa module get an update)


Having all that said, it would be great to have a dropdown menu under:

Zentyal >> Groupware >> General configuration settings

to tweak the indexing frequency.


Best,

Marcus

Installation and Upgrades / [Zarafa WebAccess] Sending with your alias email

« on: February 20, 2011, 04:58:08 pm »

Hello,
I faced a problem few weeks ago.  I wasn't able to send out using an alias email with the Zarafa WebAccess.

I finally found out that it was a default spooler configuration that was blocking everything.

This is how I worked around my problem.

In a terminal as root user
Zentyal 2.0

Code: (terminal) [Select]

# cd / && find . -name 'spooler.cf*' | xargs perl -pi -e 's/always_send_delegates = no/always_send_delegates = yes/g' && find . -name 'spooler.cf*' | xargs perl -pi -e 's/allow_redirect_spoofing = no/allow_redirect_spoofing =  yes/g' && mkdir -p /etc/ebox/stubs/zarafa && cp /usr/share/ebox/stubs/zarafa/spooler.cfg.mas /etc/ebox/stubs/zarafa/spooler.cfg.mas && zarafa-spooler restart
Zentyal 2.2

Code: (terminal) [Select]

# cd / && find . -name 'spooler.cf*' | xargs perl -pi -e 's/always_send_delegates = no/always_send_delegates = yes/g' && find . -name 'spooler.cf*' | xargs perl -pi -e 's/allow_redirect_spoofing = no/allow_redirect_spoofing =  yes/g' && mkdir -p /etc/zentyal/stubs/zarafa && cp /usr/share/zentyal/stubs/zarafa/spooler.cfg.mas /etc/zentyal/stubs/zarafa/spooler.cfg.mas && zarafa-spooler restart
Zentyal 3.0

Code: (terminal) [Select]

# sudo sed -i 's/zarafa_always_send_delegates = no/zarafa_always_send_delegates = yes/g' /etc/zentyal/zarafa.conf && sudo /etc/init.d/zentyal zarafa restart
Explaining this command (Zentyal 2.x series)
It will look for 2 files on the server:
1) /etc/zarafa/spooler.cfg
2) /usr/share/ebox|zentyal/stubs/zarafa/spooler.cfg.mas

Then, it will change the lines

Code: [Select]

always_send_delegates = no
allow_redirect_spoofing = nofor

Code: [Select]

always_send_delegates = yes
allow_redirect_spoofing = yes
And at last, it will restart the Zarafa spooler service.


We are not done yet.  We now have to add our emails to the account.

Go to Webaccess >> Settings >> Compose mail >> From Email Addresses >> Add your alias


Having all that said, it would be great to have a simple checkbox under:

Zentyal >> Groupware >> General configuration settings

to enable/disable it.

Best,

Marcus
