The script /usr/local/bin/netscheme reads the current network scheme for the giveninterface, which is savedin

the ﬁle /var/stete/network/scheme.$INTERFACE.

/usr/local/bin/netscheme:

#!/bin/sh

INTERFACE=$1

SCHEMEFILE=/var/state/network/scheme.$INTERFACE

touch $SCHEMEFILE

cat $SCHEMEFILE

The twointerfaces eth0 and wlan0 and their associated schemes are managed by the twoscripts /usr/local/bin/

eth0 and /usr/local/bin/wlan0, respectively,which differ only in the deﬁnition of the assigned interface.
