Thanks to all who offered assistance. Darren Dunham pointed me to my
problem which prevented my virtual interfaces from coming up properly:
Not that I don't believe you, but could I see the output for
wc -l /etc/hostname.*
If they don't all say '1', then that's your problem.
Indeed, when I had edited the /etc/hostname.eri* files, I inadvertantly
added a second blank line. Once I removed the blank line, I rebooted
and my interfaces are now properly automatically configured.
Most others suggested I be sure I didn't muck up my /etc/hosts or
/etc/hostname* files as specified below by Allan West:
We use many virtual interfaces on our machines, and make a file for each
one named:
/etc/hostname.INTERFACE
eg.
/etc/hostname.hme0
/etc/hostname.eri0
/etc/hostname.eri0:1
Each file has the hostname for the interface, eg.
machine1.domain.org
machine2.domain.org
web.domain.org
and those names match entries in /etc/inet/hosts to get their IP address.
Do you have each hostname in the /etc/inet/hosts file for lookup?
