Email and Groupware / Re: Two folders for spam/junk in Sogo. why?
« on: May 16, 2023, 10:16:56 pm »
In case there's some interest, think I've found a fix or workaround:
in /usr/share/zentyal/stubs/sogo/sogo.conf.mas you should add the line:
SOGoJunkFolderName = Spam;
That seems to merge both folders into a single one
in /usr/share/zentyal/stubs/sogo/sogo.conf.mas you should add the line:
SOGoJunkFolderName = Spam;

Email and Groupware / Two folders for spam/junk in Sogo. why?
« on: April 27, 2022, 04:39:01 pm »
I wonder what's the difference between Junk folder and Spam folder in Sogo interface.
I think Junk comes with Sogo by default and Spam is created by Zentyal. Is there a way to unify and merge those two into only one? It's very confusing to our users.
I cannot seem to find where they are created in dovecot and/or sogo config files. Plus, It's not clear which is the folder spamassassin filter learns spam from.
Any help would be appreciated!

Other modules / Re: Endless login popups from Proxy
« on: December 29, 2021, 03:06:15 pm »
UPDATE: Better solution
After using my "all" workaound I've run into a new problem: When a user belongs to multiple groups and those groups have to different profile rules. If any of those profiles uses whitelists that block sites " not listed", squid won't let the user access sites that were whitelisted in another profile.
So, the solutions I've foiund is to remove the lines "http_access deny authorized grp~MYGROUP" altogether. That's because there's already a rule denying all access to everyone at the end of squid.conf and this way; So that will let squid check if a user can access domains that are whitelisted in a different group before denying access.
Hope this helps!!

Es este bug?.

Aparentemente es provocado porque caduca el tiempo de sesion de webadmin
provisoriamente se arregla reiniciando el modulo webadmin "sudo zs weabadmin restart"

Other modules / Endless login popups from Proxy
« on: November 09, 2021, 10:49:01 pm »
I've been using Zentyal 2.2 for a long time but now I'm preparing to migrate to 7.0
I've installed 7.0 but I'm experiencing problems with proxy module:
I need to use a filter profile that lets a group of users surf only to specific sites. So I add those domains in a list with their " allow" rules. I also enable the checkbox "Block not listed domains and URLs".
The problem is that all borwsers keep on asking for login credentials. (Same issue experienced by this users: https://forum.zentyal.org/index.php?topic=22446.0 )
I think I've found the solution.
According to Squid Wiki: https://wiki.squid-cache.org/action/show/Features/Authentication?action=show&redirect=SquidFaq%2FProxyAuthentication
we could use the "all" hack in squid.conf. That is, we should add "all" at the end of the deny ACL
excerpt from original squid.conf
fixed squid.conf
With this last line squid accepts login credentials from browsers and let users surf to the allowed domains and deny all others. There are no more endless login popups.
Developers: do you think you could add this fix (or a proper one) ?
Thank you!

Installation and Upgrades / Error restoring Config Backup
« on: October 27, 2021, 03:28:55 pm »
I'm trying to restore a configuration backup on my up-to-date Zentyal 7.0 but I get the error:
I think the error is that there are 2 backslashes in the file string. Maybe the problem is in Samba.pm file maybe in the declaration of the constant?
I couldn't find an answer online.
Code: [Select]

Error output: ln: target '/var/lib/samba/bind-dns//dns/sam.ldb.d/' is not a directory: No such file or directory Command output: . Exit value: 1

Email and Groupware / Re: Fetchmail and Gmail: Oauth required [SOLVED]
« on: January 09, 2020, 11:53:07 pm »
It seems that in 2021 Google will enforce the use of Oauth and block access to "Less secure apps"(LSA)
They sent an email to all admins to take actions.
This is part of their announcement,
Access to LSAs will be turned off in two stages:
June 15, 2020 - Users who try to connect to an LSA for the first time will no longer be able to do so. This includes third-party apps that allow password-only access to Google calendars, contacts, and email via protocols such as CalDAV, CardDAV and IMAP. Users who have connected to LSAs prior to this date will be able to continue using them until usage of all LSAs is turned off.
February 15, 2021 - Access to LSAs will be turned off for all G Suite accounts.
Let's hope Zentyal can solve this on time!

Installation and Upgrades / Re: VLAN configuration issues.
« on: May 24, 2012, 05:07:01 pm »
Oh.. ok. So you simplified your scenario to post in this forum 
.
You should take into account that Zentyal is tagging with 1 the frames that go through eth0. Maybe your switch is discarding that traffic and that is why it doesn't respond to ping. Take a look at your switch configuration as I think your problem is on port 49 setup.
PS: I don't know why zentyal doesn't allow us to set an IP address for the untagged eth0 interface while it is configured as trunk (802.1q) (You can set it up on the console though.)

Installation and Upgrades / Re: VLAN configuration issues.
« on: May 23, 2012, 04:58:27 pm »
It seems you don't need VLAN tagging. What you need is to set up zentyal as a simple gateway between your LAN and your ISP. You don't even need to configure the port on your switch.
As you have two network interfaces you just need to set eth0 as internal and eth1 as "external".
you use VLAN tagging (802.1q) when a port on your switch has to carry traffic for different Virtual LANs (called Virtual because you just have only one switch)
For example: if you would have had only one NIC that received traffic from your LAN (untagged) and also traffic from your ISP through Virtual LAN (802.1q tagged frames).

Installation and Upgrades / Execute custom code on event?
« on: May 09, 2012, 11:13:24 pm »
I wonder if it's possible execute custom code (eg shell script) when an Event takes place.
Maybe have a new dispatcher or something.
Actually, I want to run some code when my internet goes down. (The code would access my router's web admin page)
Any help?

Installation and Upgrades / 2.3: Cannot add Group's policies in HTTP Proxy module.
« on: May 03, 2012, 12:59:17 am »
I'm trying to use HTTP proxy module to authorize and filter users internet navigation. After adding users and groups to the system I define a filter profile. When I try to bind that filter profile with a group in "Groups' policies" I get the error: "An internal error related to a template has occurred. This is a bug, relevant information can be found in the logs."
Output of /var/log/zentyal/zentyal.log
I've installed Zentyal 2.3 (64bits) from its own CD and also from PPA into a clean Ubuntu 12.04 installation and upgraded all packages. In both systems I get the same result.
Do you know how to solve this situation? any help will be appreciated!

Installation and Upgrades / Re: How to add network cards not detected by Zentyal
« on: September 12, 2011, 11:52:51 pm »
I'd say, that is not a problem with Zentyal but with Ubuntu.
I experienced something similar with the onboard NIC card in my Intel mobo. In my case the solution was to upgrade the Linux kernel to 2.6.38 version. Lucid repositories don't have that kernels so you'd have to add them manually or with new repositories.

I recently installed a test Zentyal box but it does not detect an onboard gigabit card. How do I force it to use a card or add an additional card? Zentyal 2 RC2

Spanish / Re: ¿Cómo restringir el envío y la recepción del correo por dominio?
« on: September 05, 2011, 10:21:07 pm »
Hola,
Creo que no hay una opcion en Zentyal para lo que buscas.
La solucion estaria en configurar Postfix de manera manual.
Fijate en este link:
http://www.freespamfilter.org/forum/viewtopic.php?t=659
Modifican /etc/postfix/main.cf y generar listas hash de usuarios y de sitios bloqueados.
Seria bueno tener opciones en Zentyal para esto: algo muy parecido a las configuraciones que ya tenemos en HTTP proxy.
Suerte
