Just FYI, you can use the local mac address on each installed ether controller
by setting the Sun eeprom variable local-mac-address?=true
Sun's ether cards *do* in fact, have unique mac addresses, but Sun's tradition
is to use the eeprom mac address for the entire box on all interfaces.
An alternative method (which I kind of like) is a setmacaddr init script:
#!/bin/sh
for iface in 1 2 3; do
if [ -f /etc/hostname.hme${iface} ]
then
ether_hme=`/sbin/ifconfig hme0 | /bin/tail -1 |\
/bin/sed -e "s/8:0:20/8:${iface}:20/g"`
/sbin/ifconfig hme${iface} ${ether_hme}
fi
done
(note: the sed script returns a string "ether 8:0:20:xx:yy:zz" so it already
has the ifconfig "ether" command in it, followed by the mac address)
This allows the host to retain the same last 3 octets on all interfaces -
which I find useful - and let the vendor part denote *which* interface - which
I also find very useful. It works fine unless you also have equipment from
another vendor whose mac addresses happen to start with 8:1:20, 8:2:20, etc.
;)
You should call this script as soon as /usr has been mounted, right after
/etc/rcS.d/S40standardmounts.sh.
Sometimes it returns a spurious (?) "device busy" error, but it sets the mac
address anyway. Seems to do no harm.
