Subject: [gentoo-user] another "headless device"-question: In search of the LAN
Date: Tue, 30 Sep 2014 12:12:34 +0200 [thread overview]
Message-ID: <20140930101234.GC3828@solfire> (raw)
Hi,
For a device (beaglebone black) I am looking for a solution
of the following problem:
This little computer boots a fully blown Gentoo linux. It is
used mostly as headless device (capturing data from attached
sensors).
From time to time I want access it via LAN.
If the device was booted without LAN attached, the configured
ethernet was not found and dhcpd fails.
So Gentoo goes into "no LAN"-mode (or something like that).
Is there a less "waiting for the timeout"-prone way to refresh
the status of the LAN beside putting the accoring init-script
into a cron job ???
Is there a way to check, whether a RJ45 was plugged into the
device and if so to start init-script then?
Thank you very much in advance for any help!
Best regards,
mcc
