Installation and Upgrades / Re: Cannot delete BR1 interface, bug or intentional ?

« on: October 10, 2013, 07:16:52 am »

I would not have pressed Y either...
Have u tried to sudo apt-get remove zentyal-virt
To manually deconfigure br1 use:

Code: [Select]

sudo ifconfig br1 down
# sudo brctl delif br1 xxxx  # where xxxx is a "each" of brctl show -> interfaces result
sudo brctl delbr br1
# then recall the zentyal interface and see if it's still there (it shouldnt)

Installation and Upgrades / Re: Where is the virtual management module in Zentyal 3.2?

« on: October 09, 2013, 08:20:10 pm »

... I'm considering develop a module for a kvm solution most highly adopting from an all ready existing open source web solution.

You may want to have a look at virt-manager as a simple solution if you dont need to control a mass server center.

If you assign an external IP address to your hypervisor, make sure the only services answering on the external IP have been secured. In my opinion this is not a good practice though.

Sorry to disagree, the practice is ok though you may loose a little bit of speed. But, if you have administrators (and dont know exactly their skills) on the embbeded KVM, you will want to control the inet by a fw below the VM. You can gain back speed using the full setup - like hugepages, vhost-net, virtio, ksm, lvm - and nothing is lost so far.
Indeed I also favorite to use bare metal as hypervisor and put the real functionallity in the vm's, most of them are more speedy, with previous said technics, than running on bare metal.

You may want to have a look at /etc/libvirt/qemu/networks/autostart

• If you find an *.xml or link to an *.xml file then remove the link and do a sudo service libvirt-bin restart
• If you want the functionality back you may want to try sudo apt-get install virt-manager which gives you a nice interface to KVM/QEMU machines. Remove the autostart flag within!
• If you do not want to use libvirt anymore, you should uninstall libvirt-bin sudo apt-get remove --purge libvirt-bin to gain system resources back.
• If you are going to use it later, it's enough to remove the autostart entries. You can also edit the xml files to your needs after doing a sudo service libvirt-bin stop

This should not be a show stopper, couldn't it be done in a async way (i.e.Background) without delaying bootup time.

I've corrected a typo in the former script (online version), you should use the newer version above!

Top script Markus, used to do it by hand before.

Thnx for the applaud

I have often wondered why bonding for network throughput and redundancy isn't part of the defualt Zentyal offering.
Its a fairly simple method and a common requirement if you have more than a couple of users.

Is there any reason this isn't a Zentyal offering?

I guess - not enough questions for this solution.
We use it because architects have big drawings stored in files wich are loaded from and saved on the server. If all people are working the systems response is better using both interfaces.

Frage funktioniert der Ansatz auch noch bei der 3.2-Version?

Ich bekomme ihn nicht zum laufen, oder ich habe eine Zeile vergessen zu editieren...

The script is being used in 3.2 now, too.

Without further detail, it's hard to know, what goes wrong.
Can you execute the script by hand? See /etc/network/interfaces for results and post it here.

Installation and Upgrades / [Solved] How to delete DNS entries (not visible in GUI)

« on: September 23, 2013, 10:53:50 pm »

Zentyal Core: 3.1

A TXT entry was made without hyphen, resulting in ...
my.domain.            259200  IN      TXT     "v=spf1" "mx" "a" "a:192.168.n.n" "-all"

The new/correct entry was added ...
my.domain.            259200  IN      TXT     "v=spf1 mx a a:192.168.n.n -all"

Then trying to change this one to ...
my.domain.            259200  IN      TXT     "v=spf1 mx a a:192.168.n.n include:provider.domain -all"

leads to the following result:

$ dig my.domain TXT
my.domain.            259200  IN      TXT     "v=spf1" "mx" "a" "a:192.168.n.n" "-all"
my.domain.            259200  IN      TXT     "v=spf1 mx a a:192.168.n.n -all"
my.domain.            259200  IN      TXT     "v=spf1 mx a a:192.168.n.n include:provider.domain -all"

Only the last entry is visible in the gui, how can I delete the other two?

Thanks for advise
Markus

Installation and Upgrades / Re: [Solved] Zarafa update: All data gone

« on: September 20, 2013, 10:25:58 pm »

Thanks pstrebel!
Btw: How did you trigger the upgrade to 3.2? Just changing the sources.list to 3.2?
Is it a migration from 3.1 (upgrade) or an update. Did you have any issues with the samba part?

In deed, the link solved the prob. I will let my hands off from updates for now until there is a stable status. Trying/testing software and risking data are two different worlds. I thought it is a beta test, that looks alpha to me.

« on: September 15, 2013, 06:47:17 am »

After the last update of the zarafa module all data is gone (cal,adr). There should be a warning before upgrades.

Is there a way to access the former database?

You can use rdp on an Ubuntu client and get a windows desktop from a windows terminal server, but I doubt that is what you want.

KVM, would finally be the choice in this case
