I've been trying to add several addresses to the interface. I've done this
many times but my newly upgraded 2.5.1 does'nt let me add addresses.
This is what I do:
ifconfig hme0:1 www.somedomain.com netmask 255.255.255.128 up
Then I also make /etc/hostname.hme0:1 with www.somedomain.com. in it. The
DNS is working fine.
When I restart, Solaris seems to forget above settings.
