How to set up static IP in 12.04 and avoid these start-up delays?
 

I have just upgraded a little server system from Ubuntu Server 10.04 to
Ubuntu Server 12.04, the upgrade went fairly smoothly and it's basically
all working OK.

However there is a very annoying delay has appeared in the boot
sequence, while the moving dots display during startup two messages
appear:-

Waiting for network configuration...
[waits for 40 seconds]
Waiting up to 60 more seconds for network configuration...
[waits for 60 secodns]

... and then the system finally starts up.

These delays are in the /etc/init/failsafe.conf script and seem to
happen even when the system is properly configured for static IP in
/etc/network/interfaces.

Is there any way I can configure things so they don't happen (apart from
bodging /etc/init/failsafe.conf which seems the wrong way to do it
really).

You shouldn't be getting any delays if that's the case.

Can you show the contents of your /etc/network/interfaces?

Maybe one of the hooks in /etc/network/if-up.d is broken and prevents
/etc/network/if-up.d/upstart from signalling the system about successful
network configuration? IIRC those scripts are sourced, not executed, so
if any of them has 'set -e' and then an error occurs, the others won't
even be run.

To debug the situation you could create /etc/network/if-up.d/0000debug with

exec >> /var/log/ifup-d.log 2>&1
echo "Running if-up.d scripts for $IFACE"
set -x

and then look at that log file when the server boots.

I'd put that snippet (more or less) into every script in
"/etc/network/if-up.d/" because I don't think that 0000debug'll act on
the other scripts - and it should be "chmod -x"'d.

Is this system running a GUI? I had this problem when I configured my
interfaces in /etc/network/interfaces and also had network-manager
running.

1) Your broadcast address should be "192.168.1.255".

2) You don't need to have the "broadcast..." or "network..." lines in
"/etc/network/interfaces".

3) Is "auto eth1" slowing down boot?

Should you refer to your own machine for name resolution before the others?
Don't think mine list 127.0.0.1 at all, but then I don't run a dns service
on them.

You're quite right, the 0000debug didn't do any good so I have added the
above (with the name of the script changed) to each script in if-up.d.

... listen to this space! :-)
