original question:
#############################################################
I have an Ultra Enterprise 2 with onboard 10/100 Ethernet. Attached to the
> box is a 16 gig RAID 5 Storage Dimensions array (off an SBUS SCSI adapter).
> The box has been working since fine since late November. It is running
> Oracle 7.x, and a webserver. In order to add an additional IP address, I
> decided to add an additional Ethernet card (a SunFastEthernet Adapter 2.0).

No real fix here. Most common comment was that it was a strange problem.
Apparently, Suns will set the mac address of every interface to the
primary, to simplofy routing. The solution was to disable the card, and do
the same thing through software (create a file called /etc/hme0:1 which
contains the hostname
of the second machine. Also create an/etc/hosts entry for the second machine.)
Thanks again !
