Long booting time when no network cable is plugged

[Paul Plankton]

Hi,

I'm running a BBG with Ubuntu on external microSD-card (the one from http://www.elinux.org/BeagleBoardUbuntu#Ubuntu_.2816.04.1.29 ).

When no network cable is connected to the BBG, the boot time is quite long, it comes up with a text

A start job is running for Raise network interfaces (39s / 5min 2s)

The first time value is counting and it really takes minutes...

How can I avoid this delay and let it continue without network when no cable is plugged?

Thanks!

edit /etc/network/interfaces

and comment out the two "eth0" lines..

Regards,

But this disables the network interface permanently, not only when no cable is plugged?

There is a package called ifplugd which monitors the connection and only activates the connection when a cable is plugged into the socket and the electrical connection to another system (or router/switch) is established.

Simple installation of ifplugd does not do the job - what else has to be done?

Have you configured it? It needs to know which interfaces it controls, and you need to make sure that these interfaces are not auto-started. Have you read the README in /usr/share/doc/ifplugd ?
