Network issue on Zentyal 4.2

[Arif Ali]

Hi all,

I have been trying to install Zentyal 4.2, to convert my installtion of a LDAP backed samba PDC, to get the other administrators some ease of use.

Most of the installation is good, and working very well, and actually have been very impressed, in how quickly I got the first Windows Desktop added to the domain.

The main issue I have is that when I run the following command, the network, and some of the other services fails to restart

Code: [Select]

root@zentyal:~# service zentyal restart
 * Stopping Zentyal module: openchange
   ...done.
 * Stopping Zentyal module: mail
   ...done.
 * Stopping Zentyal module: samba
   ...done.
 * Stopping Zentyal module: printers
   ...done.
 * Stopping Zentyal module: ntp
   ...done.
 * Stopping Zentyal module: logs
   ...done.
 * Stopping Zentyal module: dns
   ...done.
 * Stopping Zentyal module: dhcp
   ...done.
 * Stopping Zentyal module: ca
   ...done.
 * Stopping Zentyal module: audit
   ...done.
 * Stopping Zentyal module: firewall
   ...done.
 * Stopping Zentyal module: network
   ...done.
 * Stopping Zentyal module: webadmin
   ...done.
 * Starting Zentyal module: network
   ...fail!
 * Starting Zentyal module: firewall
   ...done.
 * Starting Zentyal module: audit
   ...done.
 * Starting Zentyal module: ca
   ...done.
 * Starting Zentyal module: dhcp
   ...done.
 * Starting Zentyal module: dns
   ...done.
 * Starting Zentyal module: logs
   ...done.
 * Starting Zentyal module: ntp
   ...done.
 * Starting Zentyal module: printers
   ...done.
 * Starting Zentyal module: samba
   ...fail!
 * Starting Zentyal module: mail
   ...fail!
 * Starting Zentyal module: openchange
   ...fail!
 * Starting Zentyal module: webadmin
   ...done.

But after bringing the network up, using ifup eth0, I can bring the rest of the zentyal modules up.

Below is an excerpt from the zentyal log, when this happens

However, if I reboot the system, I have no problems at all.

So, any ideas on this would be great

However, if I reboot the system, I have no problems at all.

In-fact, the default route never comes up, when I reboot the machine/VM. So have to add the default gw manually everytime

[Arif Ali]

I'm still stuck with this, any suggestions from anyone would be appreciated.

The only thing at the moment is, to look at the code, and try to fix it myself

Your network is misconfigured.
 

Error output: RTNETLINK answers: Network is unreachable

This message means that your default gateway is not reachable within your network, it must be in the same subnet your server is in. Either you've entered the wrong IP address as default gateway or the IP address of the gateway itself is not configured properly. Ensure your server and the gateway is on the same subnet.
