Ubuntu 12.04 "waiting for network configuration" on boot

[orasis]

Searched but didn’t find a topic related to this here. Got a small problem on ubuntu 12.04 3.2.0-24-generic-pae (desktop) running ispconfig 3.0.4.5.

Setting ispconfig to manage the network configuration causes ubuntu to show “waiting for network configuration” followed by “waiting up to 60 more seconds for network configuration..” messages on boot, and they take about 2 minutes to let the system continue to boot.

I’ve seen there is an ubuntu bug related to this:
https://bugs.launchpad.net/ubuntu/+s...wn/+bug/916890

The only way for the system to boot normally is to un-check “Network Configuration” in Server Config.

I am not sure if there is something I can do with your help, once if I don’t use the ispconfig feature “Network Configuration”, then additional server IP Addresses don’t work on (at least) lan.
There was nothing like this on ubuntu 10.04

Other than that, the system runs excellent.
Thanks for your help.


EDIT:
This is my /etc/network/interfaces

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0
iface eth0 inet static
        address 192.168.0.200
        netmask 255.255.255.0
        network 192.168.0.0
        broadcast 192.168.0.255
        gateway 192.168.0.1

auto eth0:0
iface eth0:0 inet static
        address 192.168.0.100
        netmask 255.255.255.0
        network 192.168.0.0
        broadcast 192.168.0.255
        gateway 192.168.0.1

eth0:0 is the one that causes the problem, although without it, 192.168.0.100 (the additional ip) will never work.

By the way, on page 3 of "The Perfect Server - Ubuntu 12.04 LTS (Apache2, BIND, Dovecot, ISPConfig 3)" http://www.howtoforge.com/perfect-se...ispconfig-3-p3 you add this part:

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0
iface eth0 inet static
        address 192.168.0.100
        netmask 255.255.255.0
        network 192.168.0.0
        broadcast 192.168.0.255
        gateway 192.168.0.1
        dns-nameservers 8.8.8.8 8.8.4.4

My question is, why now my interfaces have the "dns-nameservers" missing ?
cheers

You dont have to use the ispconfig network configuration feature to use ispconfig. Noramally IP addresses are configured with the config tools of the operating system directly, thats why the ispconfig network config is disabled by default and leving it off is the recommended setting.

So in your case, disable the network configuration option in ispconfig again and add the IP addresses with the ubuntu network configuration utility instead.

My question is, why now my interfaces have the "dns-nameservers" missing ?

Normally the nameservers are set in /etc/resolv.conf, they dont have to be set in the interfaces file.

Hi till, thanks for the fast reply as always.

It is excellent to use the default network tool of ubuntu for such a job.
So the default contents of /etc/network/interfaces before installing ispconfig was:

auto lo
iface lo inet loopback

I think I just go back to that.
I tried it, and only had to reboot computer for the network tool of ubuntu to be re-enabled. Also adding ip addresses there is very easy.

I only wonder what I would have to do if the server was remote ?

Concerning /etc/resolv.conf there was where I always used to edit the dns entries yes. It also takes the dns entries directly from the gui tool of ubuntu. My question was only related to your tutorial's part where you add "dns-nameservers 8.8.8.8 8.8.4.4" inside the /etc/network/interfaces

thanks for the help

Most likely the configuration in /etc/network/interfaces will work on a Ubuntu server as it works on Debian Linux and on systems based on the ubuntu server DVD. I guess the problem with the desktop is that the ubuntu desktop tool gets loaded when the desktop is started and seems to dynamically configure some network settings and ignores the classic network config file /etc/network/interfaces.

[orasis]

right... something that most likely wasn't happening on 10.04 I guess.
I got no idea where the network tool saves the static IPs now. I am very new to 12.04.

By the way, do you think there might be a way to set an ip range instead of separate IPs ? maybe this is very stupid I ask.

[till]

There is no tool to setup ip ranges available yet as far as I know.
