Installation and Upgrades / Re: FATAL: could not connect to samba LDAP server: connect: Connection refused
« on: October 25, 2013, 04:53:26 pm »
Thanks - the file & print sharing update appears to have fixed the problem for me! Interestingly, the Dashboard was showing no updates were due, but it was only when I went into the Zentyal Components menu item that I could see there were 5 udpates pending (including this one). Perhaps just a timing issue with the dashboard?

Installation and Upgrades / Re: Iptables configuration are gone after reboot
« on: October 25, 2013, 04:38:40 pm »
A fresh day, another clean install (2 actually as first did not complete cleanly) and I am now up & running as expected. I've done nothing different other than perhaps wait a little longer after reboot before trying to install/configure the required Zentyal modules from the GUI (5 mins as I was grabbing a much-needed coffee!). All I can assume is that it takes a little longer to start the various Zentyal / underlying Ubuntu services than expected? Having done 5 installs in the last 3 days, I at least feel familiar with the process now

Hi - I've got a clean 3.2 install, and was trying to backup the config to remote.zentyal.com (from the import/export configuration menu option), and got the same error message. Did you get a resolution to the problem?

I saved the existing zentyal.log to zentyal.log.saved and 'touch'ed a new, empty log file. I then rebooted to see what we got, and there are a few errors (and warnings), see attached (I've anonymised the public IPs). I'm not worried (for now) about the remote services errors (seem to be username/password related). There is an LDAP error which I assume is unrelated to network routing, and likewise for Samba (I renamed the host yesterday, but Samba still appears to be trying the old hostname) - perhaps this is giving a clue as to the issue - could it be related to the renaming of the host yesterday (which I did through the Zentyal GUI)?
I'm wondering if a clean install might be the best way forward...start with a clean sheet, get the hostname right, and see what happens?
UPDATE: tried a clean install - used network details (public IP, netmask, gateway IP) provided by serviced office and successfully installed (ie. it downloaded all it needed from the internet during installation). Got as far as the Zentyal GUI, logged in and after login got "Waiting until Zentyal is ready..." - have basically lost internet connectivity again. This time, ifconfig shows only eth0 (eth1 not yet configured) and gateway is not present. However, if I add it manually now and restart network services, it no longer connects. Time to go home, I think, and come at it again in the morning with a clear head!

Yep - rebooted and the gateway entry is now missing from eth0 in the interfaces file, and internet connectivity lost. Added manually, and working again. Does it matter what name I assign to the gateway in the Zentyal GUI (it is currently set to gw)? The IP address of the gateway was provided to me by the serviced office network team (along with the public IP and subnet mask)...

Ok, thanks - thought I was going mad!
When I installed from CD, I had internet connectivity - eth0 was (by default) set to DHCP and picked up a private ip 10.x.x.x (I am in a serviced office with internet connectivity provided direct to the floorports). They had to repatch something to allow the public IP to be presented on the particular floor-port in question. It was at that point that I set the config as above, and after applying the changes lost connectivity. I used the command line to run route -n which showed no gateway as being defined, hence why I tried manually adding it...after which everything worked again. I'll reboot the server again to confirm that the settings are being lost despite being defined in the GUI - back soon...

That's entirely possible
At the Zentyal GUI level, eth0 is defined as external in Network --> Interfaces (i.e. the External (WAN) checkbox is ticked), and it has a static public IP assigned. No virtual interfaces defined on eth0. eth1 is defined as internal and has a static private IP.
The gateway is defined on eth0 in Network --> Gateways, and is enabled and set to the default gateway (as it is the only one). All the settings are in the post above - I don't have any screenshot software installed on the server, and am connecting clients today (all being well!!), as this is a brand-new installation for a small business I am working in. Once I have an operational client I should be able to provide screenshots if required!
I have not configured any static routes in Network --> Static Routes.
In DHCP (under the Infrastructure menu), eth0 is disabled for DHCP, and eth1 is enabled for DHCP (and has correctly allocated an internal IP address from a predefined range to a network printer).
So - I think I've done everything to get internet connectivity working on eth0, but it doesn't seem to work unless I manually add the gateway to eth0 in /etc/network/interfaces and restart networking....or have I missed something?

Hi - sorry, the documentation confused me a little with /etc/zentyal/stubs and /usr/share/zentyal/stubs, but looks like my installation is ok!
Yes, basically on reboot the gateway is being dropped from the interface details in /etc/network/interfaces (there is no gateway defined at all after reboot). This prevents any internet access and also causes the Zentyal web interface to fail to load (presumably as it is trying to contact the config backup at <servername>.zentyal.me), failing and hanging.
optadmin@ocsrvgw01:/$ cat /etc/network/interfaces
auto lo eth0 eth1
iface lo inet loopback
iface eth0 inet static
address 95.xx.xx.98
netmask 255.255.255.252
broadcast 95.xx.xx.99
iface eth1 inet static
address 192.168.0.1
netmask 255.255.255.0
broadcast 192.168.0.255
If I manually add the gateway on eth0 and restart networking services I can then access both the internet and the Zentyal web admin:
optadmin@ocsrvgw01:/$ cat /etc/network/interfaces
auto lo eth0 eth1
iface lo inet loopback
iface eth0 inet static
address 95.xx.xx.98
netmask 255.255.255.252
broadcast 95.xx.xx.99
gateway 95.xx.xx.97
iface eth1 inet static
address 192.168.0.1
netmask 255.255.255.0
broadcast 192.168.0.255
The gateway is also configured within Zentyal Gateways Configuration as follows:
Enabled: Yes
Name: gw
IP Address: 95.xx.xx.97
Interface: eth0
Weight: 1
Default: Yes
but it seems that this is not being picked up by the Networking element of Zentyal 3.2?
And here is my current setup after manually adding the gateway & restarting networking services:

Installation and Upgrades / Re: Iptables configuration are gone after reboot
« on: October 24, 2013, 10:45:35 am »Start reading this, part of documentation BTW
Hi - having read the linked documentation above, I thought this would be the solution to my problem (default gateway on external NIC keeps getting deleted on reboot - clean install of Zentyal 3.2 from CD, and upgraded via apt-get). The functionality provided by Stubs and Hooks looks like it will provide huge flexibility.
Unfortunatley, when I went in search of /etc/zentyal/stubs, the directory does not appear to exist on my installation. All I have is:
optadmin@ocsrvgw01:/etc/zentyal$ ls -al

Following a quick find / -name stubs -type d -print, I found the stubs directory under /usr/share/zentyal (and it appears to contain the .mas scripts referenced in the article above)....so not sure if there is something peculiar with my installation (I just accepted the defaults with the exception of having manually partitioned the disks for RAID5), or whether the documentation needs updating for 3.2. I'll try using these stubs to see if it fixes my gateway issue.
However, the gateway is defined within Zentyal for eth0, so is there a reason why Zentyal appears not to recognise the gateway? I'm a Zentyal newbie, but have been using Ubuntu (server & desktop) for a few years now - so any pointers/suggestions would be greatly appreciated!
PS I should probably add I have 2 NICs, eth0 is the external NIC and eth1 the internal. eth0 is set to a static public IP (DHCP disabled), and eth1 is set to a static private IP (DHCP enabled as I want this server to provide DHCP services for the internal network). Thanks!
