Installation and Upgrades / Zentyal LDAP and NAS (Openmediavault)
« on: February 27, 2014, 08:38:14 pm »
I have zentyal 3.3 installed and am trying to connect my NAS to its LDAP.  I have opened port 390 and restricted connect to only allow my NAS IP.

When I used to run zentyal 2.2 I had no issues connecting openmediavault to the zentyal LDAP server (port 389 in old version).  However when I follow the same steps with the newest version of zentyal I can not get it to connect.  I show in the firewall logs that the connection is accepted (at firewall level), but I don't see a user list in the openmediavault interface.

Is there something different about the LDAP server in zentyal 3.3 ?

On a seperate note when I try to add the NAS to the Samba/Cifs network it is not being seen by network explorer, so it does not show up as browsable.  I am wondering if Samba4 is the reason for the my LDAP issues and also why the NAS is not showing up for the windows machines..

Thank you !!

Installation and Upgrades / Ngninx Function in Zentyal 3.3
« on: February 19, 2014, 10:30:31 pm »
Could anyone please let me know what is the function of Nginx in Zentyal 3.3 ? 

On Zentyal 2.2 I manually added Nginx and used it as reverse proxy listening on ports 998 & 998.  I would than use port forwarding and forward any traffic coming from web to my zentyal on porst 80 and 443 to the reverse proxy Nginx.

I need to have this function back in zentyal 3.3, but I don't want to break the Nginx configuration.

Thank you for any help.

Installation and Upgrades / Nested folders with different ACLs ?
« on: February 11, 2014, 07:14:52 pm »
Hello everyone.

I have been running zentyal 2.2 for several years and now (after some internal testing) have switched over the latest 3.3 (fully updated).  The switch went pretty well and so far I have no issues that I can see.  Even have all the emails from Zarafa transferred onto the new server.

My only question is it possible to share a directory though zentyal which contains different sub-directories with different ACL's

In version 2.2 I had every directory mapped separately (zentyal/shareA ; zentyal/shareB ; etc.....) which works fine, but it just makes for a lot of different directories.

I want to know if it is possible in 3.4 to map one main directory zentya/main which contains all the sub directories.  However have each subdirectory have different ACL's so that different users can access them.

zentyal/main = everyone can mount this share
zentyal/main/marketing = marketing department
zentyal/main/engineering = engineering department

Is this possible ?

I currently have a zentyal 2.2 system running.  However once zentyal 3.2 comes out I was thinking of making the migration.  I don't mind having to recreate all the firewall rules and special custom features I have done to my 2.2 installation.  However I have some questions on how I would migrate zarafa, clients and their work stations.

My zentyal 2.2 machine has the users and groups module running.  I have 10 windows 7 machines that authenticate their local profiles against the zentyal server (domain is zentyal.lan).  The total client count is actually around 15 people, but I do not use roaming profiles. 

Also each client has a zarafa email account.  Zarafa MySQL database gets backed up every night using a script.

When I switch to Zentyal 3.2 I know that I will have to create a new domain and probably recreate all the users.  Does anyone know how I would migrate each users local profile on each windows 7 machine to the new domain.  I don't want the users to loose any data they might have saved on their desktop.

My second question is how would I get the clients emails back.  I don't think that a zarafa MySQL restore will work since this will be a completely different system.

Since I have very few users I don't mind having to migrate each user manually, but I just need some direction.


For any other data stored on zentyal I will use my backups to restore it (shared folder data and any files clients saved on their network folder).

Installation and Upgrades / General Samba4 domain question
« on: February 19, 2013, 10:05:35 pm »
I read the new published instructions on how to setup a standalone zentyal server with samba4.

In the instructions it says that it is very important to configure the proper domain name which will be used by samba4 module.
In the instructions it gave the domain as zentyal-domain.lan

It later shows that this domain is pushed onto the windows7 clients through DHCP.

My network however does not have one single domain name.  I use Vlan's to segregate my lan into individual zones.  Each zone has its own domain name:  Control.lan ; home.lan ; wifi.lan, guest.lan etc....  several of the domains need to have the clients connected to the domain controller.  How would I do this with samba4?  Is it possible to have a segmented setup like this and still connect it properly to the domain controller?

Installation and Upgrades / Zentyal 2.2 - Sudden Problem after 1 year
« on: February 17, 2013, 05:56:29 pm »
Need some help or thoughts on the following issue.

My main zentyal 2.2 server has developed a strange issue after performing perfectly for about a year.  The system runs 24/7 and has been running without a reboot for the last 140 days (no issues). All of a sudden I lost all connection to the system.  I could not connect through ssh or any other method.  I hooked up a monitor and keyboard, but  no matter what I did nothing appeared on the screen.  I had to do a hard stop and restarted the system.  Since then however this issue keeps coming back after the system has been running for about a week. The zentyal logs that I have looked at so far do not show me anything.  Basically they just stop recording.... all the munin graphs and zentyal graphs just go dead.  The server is on, but nothing is happening.

All modules are running on Zentyal 2.2 system.
Some info on the system:  Dual Intex Xenon processors, 24 gigs of ram, single power supply connected to UPS,  4 gigabit lan ports.  I use mdadm software raid.  2x32 gig SSD in raid1 using LVM & EXT4 for base system; 1x32 gig SSD which is split between swap and /var/logs; 2x300 gig 10,000RPM raptor drives in raid1 for /home partition; 7x2TB 5900RPM drives in raid6 (mostly media files) .  The hole system gets backed up using rsync to a NAS runnig OpenMediaVault

Other than the base zentyal 2.2 system I have installed an UPS monitoring program, virtualbox, subsonic and munin.  I have also tweaked my raid6 performance, but nothing else.

I can't find anything in the log files I have looked at for what could be causing this type of failure.  It seems to happen randomly... I thought it might be some sort of hardware failure, but not sure.... when I restart the system everything works perfectly.

Any advice or directly will be great !!  (This is my production system)

I have several remote clients which OpenVPN to connect to the Network shares and other servers running on the LAN. Everything works fine there.

Today I however tried to connect to one of those clients using remote desktop (the user was having some issues).  I however was not able to connect.  Remote desktop works if the client is at the office and connected to the network, but I can not get it to work if the client is remote and just connect through OpenVPN

Is it even possible to connect to the client?  I tried to ping the client using the OpenVPN address (192.168.160.2), but that did not work either.

Any help or direction will be most appreciated !!!

Thank you !!!

Installation and Upgrades / Traffic Shaping Zentya 2.2 - possible issue
« on: October 23, 2012, 05:09:58 pm »
Good Day,

I have a zentyal 2.2 server running as my gateway, proxy, traffic filter, + almost all other modules. 

On the server I have also installed subsonic which runs on port 4040 and is accessible from the outside.
I also have another subsonic server internally on my LAN which listens on port 80 and is accessible from the outside through the use of a reverse proxy. 

I can access both subsonic servers with no issue and I can either listen to music or stream video content depending on which server I connect to.

I have recently tried to implement some traffic shaping rules for these two servers since I have very limited upload bandwidth (3 Mb/s).  I have configured the rate of my external interface for both upload and download.

In the traffic shaping module I created a port based rule on the external interface that would limit upload traffic from subsonic on port 4040 to 1000 Kb/s.  I have also created a Layer-7 filter that listens for any music or video and limits it to 1000 Kb/s.

However I do not see the rate being limited at all.....  Is there a way I can check to see if the traffic filter is working?  It seems that no matter what max limit I put into the traffic filter for either rule nothing actually happens.

Any ideas?

Installation and Upgrades / External server getting users from LDAP???
« on: September 19, 2012, 06:32:16 pm »
Good Day,

I have zentyal 2.2 running with almost all modules installed.  Inside my network I also have an Alfresco and Subsonic server running.

Is it possible to setup LDAP authentication between those servers and Zentyal??  I know when Subsonic is installed on the same server as Zentyal you can make it use LDAP authentication, but in this case it is a separate server.  Also since I don't have a master slave architecture I do not know if this is possible.

If all I want is just user authentication should I just open the LDAP port on Zentyal and then just Point Subsonic or Alfresco to it?? 

Any direction would be great !!!

Thank you !!

Installation and Upgrades / /root partion filling up ???
« on: August 16, 2012, 03:22:18 pm »
Hello Forum Members,

I am running zentyal 2.2.x (latest production version with everything upgraded).  The system runs good for the most part with no issues unless I am the one causing them.

However I do have a question with regards to my ever expending /root partition. 

I have my system installed on a software raid 1 which consists of two SSD drives.  I have given /root partition 10 gigs.
On another SSD drive I have a partition for /var/logs which has 5 gigs. /home is mounted on a different raid1 array.

When I first installed zentyal .... the system was taking up 6 gigs of my system drive + 1 gig for proxy cache.
Since then the system just keeps growing and now it is taking up over 7.5 gigs.  This 7.5 gigs + 1 gig for proxy cache only leaves just a bit over 1 gig free and with the system expending it will eat that up quickly.

I don't understand what is making the system keep growing and growing (sine my last complete reinstall it has only been 3 weeks).  My logs are on a separate disk so that should be not causing the expansion. I back up the system to another server so no backups should be on zentyal itself.
When I break the /root partition down to see what is taking up the most space I find that /usr is about 1.9 gigs and /var is about 5.6 gigs.  In var I find that /var/cache is over 2 gigs (this is the biggest chunk)..... does this seem normal ???

My question is this normal for the system to keep growing like this ??? 

How can I move /var to a new partition?  I have another raid1 array with about 10 gigs which I can allocate to just /var  This should give me a lot more space.

Installation and Upgrades / Creating DMZ with Zentyal
« on: June 25, 2012, 12:28:40 pm »
I have a question on how to properly create a DMZ using zentyal. 
- for this example lets says I have 3 interfaces:  eth1, eth2, eth3

eth1 - I mark as external and connect it to my ISP provided router/modem
eth2 - I mark as internal and connect to my lan switch

eth3 - This is the interface I want to be for my DMZ.  Should I be marking this connection as external or internal ??
currently I have this connection marked as internal and then use firewall rules to restrict access to and from the DMZ zone.
However I am not sure this is correct.... perhaps I should mark this as an external interface....
If so how would I route traffic from the DMZ zone to the internet......

Any help with setting up the zone properly would be great !!

Installation and Upgrades / Migrating to new disks??
« on: May 03, 2012, 03:42:11 am »
Here is my situation.

Currently I have zentyal 2.2.7 installed on 2 x 500 gig 7200RMP drives which are in a software raid one.  I have divided those disks into several partitions.  One partition 80 gigs (way to big) is for my root partition, One 20 gig partition is for swap (not sure why I did this now that I look back at it), one 400 gig partition for home.

One of my disks after many years of service is about to fail (based on the information I have seen from my Munin graphs and the fact that it looses sync with the other raid volume).

Now I have some spair disks 2x 32gig SSD, 1x 16gig SSD and 2x 300gig 10000RPM Raptor drives.  Is there a way to somehow migrate my system to use these disks.

Basically I want my root partition on the 32 gig SSD which I will setup in software raid1
I want swap to be on the 16 gig SSD
My home and /var/logs to be on the 10000RPM drives which also will be in software raid1

Can I somehow make this move without having to reinstall my entire operating system and home folder ???

If I do have to reinstall the system.... would I be able to restore it using my backups???  I mostly don't want to loose my Home folders or really any of my setup... including zarafa emails and my current PDC users and settings.

I was planning on using the EXT4 file system which is what I am currently using.....

Any advice or pointers are welcome.....   Thank you !!!

Installation and Upgrades / General Linux Server Question
« on: March 14, 2012, 01:31:12 pm »
Hello Everyone!!

I have a general linux question about how ram and swap are used in zentyal/ubuntu

First my setup:
Server running latest zentyal 2.2.6 with everything up to date.
Server hardware:
2x xenon E5606 processors (4 cores each)
10 gigs DDR3-1600 ram (5 slots with 2 gig sticks.... non ECC ram)
I have two 500 gig drives which I have setup in software raid1 using MDADM
I created 3 partions.  One for the root file system (30 gigs) EXT4, one for home (450 gigs) EXT4 and one I use for swap (20 gigs)
I also have 7 x 2TB seagate 5900RPM drives running in a software raid 6.

One top of my core zentyal installation I also run Virtualbox.  Which has two virtual servers running (One is a webserver and the other I am testing and Enterprise Resource Planning System).  The webserver has about 3 gigs or RAM allocated to it and the ERP system has about 1.5 gigs RAM allocated to it. 

This leaves the main system about 5.5 gigs of RAM. 

Now here is my question.  I have noticed that my system is using 2.84 gigs of swap and according to what the munin graphs are telling me I have seen a maximum of 524 pages/second of swap out.

I am trying to figure out why my system is using so much swap???  Is this normal??? 

Last night I changes the stripe_cache_size for my raid6 array from default 256 to 8192.  This has improved my write and read speeds to about 120 Mb/s (fully maximizes my gigabit lan).  However now I see my load jump during large file transfers and see a lot more swap being used in the beginning of the transfer.  As the transfer continues I see load go down. 

When I look to see what is causing the high load I always notice a lot of swap activity at the same time.  Why am I using swap when I have 5.5 gigs of RAM ????

Installation and Upgrades / Temperature Monitoring - collectd ??
« on: March 07, 2012, 02:54:22 pm »
I have seen some posts about different sensor readings in zentyal using collectd.  I have also tried to read the post and figure out myself what I should do in the situation I will describe below, but I have not been able to figure it out.

My issues is that I do not see a temperature graph in zentyal monitoring.  I see graphs for my processors, ram, load and hard drive usage...... but no temperature graph.  (no reading and no graph at all)

From reading I understand that the information is collected by collectd.  I also know that it could possibly be an issue with my motherboard.  However I now have installed zentyal on two different systems and I still don't see a graph at all (not even a blank one).

My first motherboard is an MSI desktop board ..... which I thought could be the reason.

However my second board is an Asus server board running two xenon processors.  It has ACPI and it is turned on in the bios.  However I still don't see anything.

From reading the boards I see other who have zentyal and don't see temperature readout.  In my case I don't even see a blank graph (maybe this is normal if no readings are being recorded).

My qeustion is:

What should be my first step to make sure that collectd plugin is in fact enabled for temperature monitoring.

Second what others steps should I take to diagnose the problem.... could it be a driver issue??? How would I know???

Thank you for any help.
