Answer 1

I've had a similar problem on Sparc/Solaris 7. I traced it to the fact that Solaris uses the same MAC address for all network interfaces, unless you tell it different. Find the "ifconfig" command that configures your interfaces (in /etc/init.d/rootusr) and when it's doing the 2nd interface (it does that in a "while" loop, so you'll have to test explicitly each time around the loop). A diff on my system gives:
<pre>
diff -c /etc/init.d/rootusr /etc/init.d/rootusr.old
*** /etc/init.d/rootusr     Tue Feb 20 15:55:02 2001

*** 47,56 ****
               if [ "$1" != "xx0" ]; then
                    addr=`shcat /etc/hostname\.$1`
                    /sbin/ifconfig $1 plumb
-                     if [ "$1" = "hme0" ]; then
- # Change ethernet addr of 2nd NIC
-                          /sbin/ifconfig $1 ether 8:0:20:da:b8:77 2>&1 >/dev/null
-                     fi
                    if [ -n "$addr" ]; then
                         /sbin/ifconfig $1 inet "$addr" \
                         netmask + broadcast + -trailers up \

</pre>
Of course, read the appropriate man pages (ifconfig, the See Also references in the ifconfig man page). And I must state that YMMV.
