Summary:
Given that I had a computer that had three network interfaces... I assumed
that each network interface had its own ethernet address. And as some of you
have noted, "by default sun assigns my ethernet address per computer" which
means that no matter how many ethernet cards you add, you still only have
one address.. Now this is fine if you have your machine on different subnets,
but not so good if the ethernet interfaces are on the same subnet.
So as suggested, I used the ether option of the ifconfig program to give
each network board its own unique ethernet address. Now since, I was unsure
what address to use, for fear of conflict... I took the address off of two
dad ethernet boards that I had for my pc laying around... I then disposed of
those network board forever.
To make the changes current everytime the system is rebooted.. I put the
following command in:
/etc/init.d/inetsvc
ifconfig le1 xx:xx:xx:xx
ifconfig le3 xx:xx:xx:xx
Where le1 and le3 are my two new network interfaces and the
xx:xx:xx:xx are the ethernet address I used....
Thanks to everyone to replied...
