Hello,

I have installed Zentyal in my Ubuntu 12.04 OS for a some time now, but today
I can't access the internet. I get "Server not found" for every web page I enter
in my Mozilla Firefox. Since yesterday I was able to access the internet!

I think it has to do with Zentyal, but yesterday I did not make any configuration..

Top right in my Ubuntu Desktop, shows that I am connected to internet through "Wired Connection"
and by typing
Code: [Select]
ifconfig in terminal I get:

eth0     Link encap:Ethernet HWaddr
            inet addr:192.168.1.8   Bcast:192.168.1.255   Mask:255.255.255.0
            UP BROADCAST RUNNING MULTICAST   MTU:1500    Metric:1
            RX packets:3105  errors:0  dropped:0   overruns:0   frame:0
            TX packets:61  errors:0  dropped:0   overruns:0   carrier:0
            collisions:0  txqueuelen:1000
            RX bytes:375798 (375.5KB)   TX bytes:7065 (7.0 KB)
       
lo          Link encap:Local Loopback
            inet addr:127.0.0.1  Mask|:255.0.0.0
            UP LOOBACK RUNNING MTU:65536 Metric:1
            RX packets:6119  errors:0  dropped:0   overruns:0   frame:0
            TX packets:6119  errors:0  dropped:0   overruns:0   carrier:0
            collisions:0  txqueuelen:0
            RX bytes:2179194 (2.1 MB)   TX bytes:2179194 (2.1 MB)
           
However, I can access Zentyal's Web Interface.

Can anyone please help me?


EDIT:   (more info)

Did you check the DNS resolutions "dig google.com"? Are you able to ping to 8.8.8.8?

I go to Network -> Tools (in Zentyal's Web Interface)
but when I ping 8.8.8.8 or google.com I get:

ping: unknown host gogle.com
connect: Network is unreachable

The same messages I get from my terminal..

Try to configure your Network interface, save changes and try again.

Oh you 're right!  :)

I configured my network as DHCP, check External and now I can access the internet!
Thank you!!! I hadn't realized that the problem has to do with leaving my eth0 unconfigured..

Hello again,

Now I am trying to create subnets using Zentyal's Web Interface, but I can't find anything..
My machine has one Network Interface Card and I want to create one subnet so as
to share ip addresses to other machines using the same network with my Zentyal server.

Zentyal Server runs in a machine with IP 192.168.x.x
(Network->Interfaces) eth0 DHCP and I want to give
other machines IPs in a range between 10.10.10.1-10.10.10.245 e.t.c.

Any help please?

EDIT:
I am still stuck on the same issue.
I think what I am trying to do is to use Zentyal as the only router through
which all PCs will be connected to the internet. The only PC to be directly connected to
the internet will be my Zentyal Server machine (wired connection). Other PCs will
access the internet through ip addresses which are given to them by Zentyal.

I have made a careful research on the internet,
but I can't find from where to start. Maybe I have to start with subneting
my Zentyal's IP 192.168.x.x so as to give a unique IP to every other computer..

Because I am a beginner, I am asking again for your help :)
Every helpful answer is welcome!!! :) :)

No internet access after installing Zentyal in Ubuntu 20.04 LTS
« Reply #6 on: December 04, 2021, 05:39:34 am »
So I tried to install Zentyal on top of Ubuntu 20.04LTS as mentioned here: https://doc.zentyal.org/en/installation.html#installation-on-top-of-ubuntu-20-04-lts-server-or-desktop

on reboot Zentyal/Ubuntu don't have IP, and netplan is removed
and obviously without network, I'm unable to install zentyal-network module
how I could resolve that ?
