Installation and Upgrades / Re: configuration for 2 virtual mail
« on: July 26, 2011, 02:40:40 pm »
Hi,
please let me jump in here.
My experience with Zarafa is on a standalone server - the situation on site is the following:
the company owns several domains, therefore the users do need to receive and more importantly also send under different mail accounts.
The Zarafa server's postfix does know about these domains and handles internal mail traffic accordingly.
Fetchmail receives the different accounts' incoming mail from the internet using pop3 and queues them into the MTA. Took a bit studying the before unknown modules and the zarafa forum, but it's working rather well.
And the users do have their standard sender's account (domain may be different for each user) entered in the zarafa configuration. For sending under another domains' label, they do have "send only" smtp accounts defined in their Outlook (could also be T-bird or any other Mailer, but of course NOT Z-Webaccess), that they need to switch to if necessary.
Zarafa here is very like the "real" Exchange: only one sender account per mailbox can be defined.
Other, but in my eyes for the users more complex method (and in my case eating more licenses): define more mailboxes per user and give send-as permissions.

Installation and Upgrades / Re: Virtualizing the Server
« on: July 26, 2011, 02:22:42 pm »
Hi,
pardon me jumping in.
I also have become a great fan of Virtualization, and by this I try to have any installation at my customers' sites as little as possible on "real" machines. Be it only for the interchangeability in case of host hardware damage.
As I read your planning, one question hops immediately into my mind: if the Samba server is on the host - how can it participate in the user/group management which will only be available after the VMs are up ...?
I do understand your concerns regarding the RAID.
On my larger hosts, I have vendor supplied Hardware RAID (Dell, 3Ware), which is configured in its BIOS and seen as one disk by ESXi.
On the other, more PC-like servers, the built-in "pseudo-RAIDs" are switched off to give me separate disks, which I use for internal copying/mirroring on a "semi-manual" basis. These machines do not run ESXi either, but VMserver on Linux or Windows, and also VirtualBox. That makes the mentioned semi-manual tasks more easy to perform, and performance is not really an issue there, too.

Installation and Upgrades / Re: ebox 1.4x - Samba 3.4.6 - full_audit problem
« on: February 28, 2011, 05:00:31 pm »
Hi again,
for the records: I found it ... but I doubt the case shall be closed.
there was one share in smb.conf defined that did not have the general "vfs objects = vscan-clamav recycle" - and that share did work properly.
As the clamav module is deactivated on the server anyways, I did a quick-and-dirty mod of the .sam file by inserting a line $av=0 into all paragraphs.
And see - it's working fine again ...
Would be glad to hear some real solution for this ...

Installation and Upgrades / ebox 1.4x - Samba 3.4.6 - full_audit problem
« on: February 28, 2011, 04:30:40 pm »
Hi,
I hope that the "old version" gets still some attention here.
After many months of running ebox 1.4.9 in a master-slave pair, today something strange happened:
on the slave, suddenly no file modifications could be done. Same evidence as from the meanwhile well known "full_audit" problem.
But - how can this occur middle of the day?
Following http://forum.zentyal.org/index.php?topic=3298.0, I did check the smb.conf - and look, there are the upper three "full_audit"-lines active. Why
Ok, commented them, restarted samba, restarted client, no change ...
Also the stub file is double and triple checked, the server has been rebooted several times, also the client(s), but we are stuck ...
A "downgrade" to whatever will not be possible, since the client PCs are Win7 ...
What can have happened, and much more important: how can I come down from this?
Any help appreciated
Michael

Installation and Upgrades / SOLVED: Support policy for "old" Version ?
« on: October 21, 2010, 09:40:05 am »
Thank you for the message.
So I'll stay happily on this stable version, maybe could even stop the updater service?, until somebody asks for a feature that is only available in the 2.0 branch.

Installation and Upgrades / Support policy for "old" Version ?
« on: October 08, 2010, 02:37:23 pm »
Hi Zentyalists,
as I don't find a more suitable place, I pose this question here. Feel free to move it to appropriate location.
I'm running now for nearly 3 months an ebox1.4 system in master/slave configuration with ~10 users Win7 / XP.
During the first weeks, there went nearly not 3 days in a row, that there did not come any software update.
Then, the announcement about 2.0 by September 1st came, the update frequency sank. Really understandable, as the development efforts had to focus into the new release.
And now, I'm on "nothing has happened unless some Linux kernel headers", kind of stuck in 1.4.9, since about a month.
Not that I'm unhappy about a seemingly stable software, but the question behind is:
Will there be any maintenance on the 1.4 level, maybe even a 1.6 to "backport" some good features from the 2.0 world? And if yes, how long can I count on this? All agreed, the support for previous versions cannot run eternally, but a overlapping time window for support looks nicer than "here's the new, switch or starve".
Reason behind is a simple one: I need in-advance planning and scheduling to make a migration, if needed by features or worse by bugs ... but I can't tell them after 4 months "hey, dear users, the new system is nice, but now I need another 3 days off your work to migrate it ..."

Installation and Upgrades / LDAP-master system messages - how to mail them?
« on: July 23, 2010, 08:45:56 am »
Hi,
in my newly configured system architecture I have the LDAP-master running only the very needed services: DNS, DHCP, and of course LDAP with users+groups.
Naturally, I want to be able to get system messages also from this machine. But in my backhead, I always see the warning "the LDAP-master may not have any services installed that are relying on users+groups ..."
How can I achieve my goal? As I'm nearly ready for deliverance, I don't want to spoil my existing machine by testing ...
thanks in advance

Installation and Upgrades / Re: [QUESTION] - DNS Replication between eBox servers
« on: July 19, 2010, 08:05:39 pm »
Hi,
that's a feature I also did look for when setting up my LDAP Master/Slave scenario.
Because what's it good for if the LDAP is failsafe, but the DNS not?
It was possible in the good old NT times to have primary and secondary DNS zones ... and I've also running this construct with a windows primary DNS and a linux/bind secondary ...

Installation and Upgrades / Re: timeouts to ebox via local lan
« on: July 19, 2010, 07:57:45 pm »Dansguardian is the actual program within ebox that handles you dns requests!!
that's why I couldn't find it on the "Server" - I must look for it on the "Master".
But, als there I don't find this process. I only have named and bind ...
Anyway - how can I set this parameter?

Hi, and thanks for the reply.
what is Dansguardian? I don't see an entry in the "ps -ef" listing.
maybe some more details for my installation:
actually this whole scenario is within a VMware box - 4 cores, 8GB, so it should be plenty enough.
There are VMs for
- Master: LDAP master, DNS, DHCP
- Server: LDAP slave, Samba
- Mail: zarafa, postfix
and for testing
- XP: workstation
As I'm still in offsite setup mode, all VMs are defined as NAT, so there is only the "real external" traffic and the VM consoles going thru the LAN. On delivery they will be switched into "Bridged" and the Host will receive another IP.
All are fixed IPs with DNS to Master, there the ebox-DNS holds all entries.
The problem is: I mark a slightly large directory (65MB) for copying and want to paste this into the user's home directory on "Server". The XP immediately switches into Offline Mode.
But that I can immediately resolve by starting the synchronisation, and then the files are transferred quickly. It does not happen on small files. But 1.7MB are big enough ...
Update1:
But - as you mention it:
I could "ping master.domain.local", but not "ping master", as I would be able within windows world.
This I could overcome by entering "Server" IP as WINS server into the XP.
Update2:
Ok, the situation is solved: I disabled the "Offline files" in "Extras, Folder options, Offlinefiles" - and all copying goes as a bliss - btw. I don't know how this could be enabled ...
Now "My documents" is moved into the Server, that's enough safety.
thank you for making me think about it

Hi,
sorry for jumping in.
I have a similar problem: my client can login, but then switches into offline mode when copying data to or from the server.
So I'd be interested in this solution, too. But: what is the ipmc service?
Thanks in advance

Installation and Upgrades / Re: Client cannot join domain
« on: July 17, 2010, 07:33:12 pm »
Update:
had nothing better to do
so I rebuilt the two eboxes from scratch, including apt-get upgrade, change to kernel 2.6.24.28-server and install vmware-toolbox.
Joined the slave into the master, created the 10 users and 4 groups, created the shared, fixed the samba "full_audit"-bug.
Then the moment of truth:
XP1 - fire up, join the domain ... wait ... hoorrayyy
XP2 (still in domain) - fire up, cannot login, ok, remove from domain, rejoin domain ... hoorrayyy
W7 - fire up, join domain - reject ... search forum, find
http://forum.ebox-platform.com/index.php?topic=4006.0 and apply ... hoorrayyy
The only thing is the server based profiles do not yet function correctly, but I could also live without them.
I don't know if I should mark this topic as solved, since I did not really find a solution (and I don't know if it reoccurs in few weeks?), but at least my project schedule seems okay again.

Hi the 3rd ...
continued testing, created a Win7 VM to join the domain.
But here again: the attempt fails after asking the credentials of the domain admin.
If I enter a wrong domain name, this is rejected. so the broadcast "does this domain exist" returns positive.
And if I enter a wrong account or password into the credentials dialogue, these are also rejected as wrong.
But then: what is the missing step ...?
