well, at this point he doesn't seem to know wether fxp0 is his first
ethernet interface. Chicken Egg problem ;-)
This is a snippet from OpenBSD's installer (it's a ksh script).
Dunno wether it works on FreeBSD, though. But should :)
# Find all ethernet interfaces
A=`dmesg | grep 'address ..:..:..:..:..:..' | sed 's/^\(.*\) at .*/\1/'`
# Find the first interface with cable plugged in
for i in $A; do
if ifconfig $i | grep 'status: active'; then
IFACE=$i; export IFACE
break
fi
done
if test "$IFACE"; then
echo Network interface is $IFACE
else
echo No network interface located. Aborting.
exec sh
fi
The status: active part could be a way to figure out which interface is
active...

Marian
