Other modules / Local DNS server not local resolver
« on: May 23, 2017, 04:36:09 pm »
Zentyal 5.0.8
Hi,
the tab Network > DNS says "The Zentyal DNS module is installed and enabled, so only the local DNS server will be used to resolve the queries. [...]". That used to work until Zentyal 5.
Unfortunately with Zentyal 5 the local DNS server is NOT the local resolver - as I can see in resolv.conf - but the DNS servers received via DHCP (DHCP is enabled for the external interface).
In short: Zentyal doesn't overwrite the DNS servers received via DHCP with 127.0.0.1 when the DNS module is enabled.

Contributions / Tips&Tricks / Features Requests / Firewall rules deployment
« on: February 02, 2017, 03:35:49 pm »
Hi,
is it possible to deploy (push) firewall rules and network objects so I don't have to enter them manually through the Webadmin GUI?

Installation and Upgrades / Error adding static host route
« on: August 19, 2015, 04:39:13 pm »
Trying to add a static host route I receive the following error:
Gateway 1.2.3.4 is already defined in the gateway table. Use a multi gateway rule instead
The command is equivalent to...
What is a "multi gateway rule" and how can I enter a "multi gateway rule"? Is there another way to enter the non-standard routing entry through Zentyal's admin interface?
This is Zentyal 4.1 development edition.

Code: [Select]
route add -host 1.2.3.5 gw 1.2.3.4 dev eth01.2.3.4 is the default gateway and 1.2.3.5 is in the same subnet as eth0 (so you normally wouldn't need a route at all as the (MAC) address is resolved via broadcast).What is a "multi gateway rule" and how can I enter a "multi gateway rule"? Is there another way to enter the non-standard routing entry through Zentyal's admin interface?

Installation and Upgrades / iptables rules without matching Packet Filter rules
« on: January 02, 2015, 12:28:52 pm »
Hi,
I noticed that the iptables output from our firewall shows rules which don't correspond to any Packet Filter rule set in our webadmin interface. The rules in question are
The IP address `192.168.201.1` does not match any interface configured on the host. How can I delete those rules?

Installation and Upgrades / Duplicate system web admin service after upgrade
« on: January 02, 2015, 11:38:15 am »
Hi,
since upgrading our Zentyal machine (don't know if it was from 3.2 to 3.5 or from 3.5 to 4.0) we have two "Zentyal Webadmin" services. Both are "system services" - which means that they cannot be edited, renamed or deleted.
One points to our default Webadmin port 444 (we changed it from the default port 443) and the other points to the new default port with nginx (8443). What can we do to delete the "rogue" webadmin service?
For people administering the firewall, this is obviously confusing, because in the firewall rule set, you have to choose a service - and there is no way to distinguish between the correct and the incorrect webadmin service.

Installation and Upgrades / no default gateway in `route` output
« on: January 02, 2015, 11:04:16 am »
Hello,
I have configured a default gateway on my Zentyal machine through the web admin interface. This works fine and I can connect to the internet. Nevertheless `route -n` doesn't show any configured default route:
It's been this way since Zentyal 2.3 on all our boxes so this looks to me as if it "works as designed". Other people noticed it, too: https://forum.zentyal.org/index.php/topic,22344.msg85995.html#msg85995
Does anyone why I can connect to the internet without a - visible - default gateway and the design behind that?

Installation and Upgrades / How to update Zentyal and keep the configuration?
« on: June 30, 2013, 09:14:49 am »
Is there a way to update Zentyal and keep the existing configuration? I tried to update from vanilla 2.3.4 (the one that comes with Ubuntu 12.04) to 2.3.24 and via...
add-apt-repository ppa:zentyal/2.3
aptitude update
aptitude safe-upgrade
..and lost (all?) of my configuration. Restore via web interface was not successful and on reboot all network interfaces were "gone" (unconfigured)...

Installation and Upgrades / Missing dbus dependency for Zentyal PPA
« on: June 30, 2013, 01:30:53 am »
Installing or upgrading 2.3 or 3.0 from Zentyal PPA results in lots of "status: Unable to connect to system bus: Failed to connect to socket /var/run/dbus/system_bus_socket: No such file or directory" errors.
Steps to reproduce:
- install 12.04 server (choose "install a minimal virtual machine" on the start screen with F4)
- install Zentyal via "aptitude install zentyal-core" (no errors)
- try to update your 2.3 install or upgrade to 3.0 via "add-apt-repository ppa:zentyal/2.3" (respectively ppa:zentyal/3.0)
- run "aptitude update" and "aptitude safe-upgrade"
result: lots of "status: Unable to connect to system bus: Failed to connect to socket /var/run/dbus/system_bus_socket: No such file or directory" errors.

Installation and Upgrades / [SOLVED] Internet Explorer blocked (please unblock!)
« on: June 18, 2013, 10:41:59 am »
[Zentyal 2.3.4]
Hello,
when I try to access the Zentyal admin web site with Internet Explorer, I get the message "Warning: Unfortunately Internet Explorer is not yet supported on Zentyal. Please use Firefox instead." and I cannot continue because the user name and password field are greyed out.
When I try to access the admin web site with another browser (say Opera), I get "Warning: You are using a browser which is not Firefox, the only one officially supported. Please, take into consideration that you might face some issues while navigating on Zentyal UI." and I can continue.
I don't think that Internet Explorer will perform worse than Opera in Zentyal so there is no reason to explicitly block Internet Explorer. Please "unblock" Internet Explorer...!
