This should be mind-numbingly simple and basic, and yet I couldn't find how to do it, either in "man ifconfig", in the OpenSolaris docs site, or Googling in desperation. I'm using OpenSolaris 2009.06.

When I try ifconfig e1000g0:0 netmask up all addresses go kablooie instead. This happen whether the network is in "automatic" or "manual" mode.

Alternatively, I could use a way to set up two static IP addresses too.

Try ifconfig e1000g0:1 blah... or ifconfig e1000g0 addif instead - IIRC the zero alias/logical interface is special on Solaris.

"ifconfig e1000g0 addif" worked! Thanks! – JCCyC Aug 5 '10 at 16:22
