IP aliases in OpenSolaris

Via http://ipucu.enderunix.org/view.php?id=369&lang=en

To have multiple IP addresses on 1 NIC, you need to make aliases.

pfexec bash
MYIP=192.168.255.5
MYSUBMASK=255.255.255.0
MYNET=192.168.255.0
MYHOST=$( hostname )
MYNIC="nge0:1"

Enable an alias:

ifconfig $MYNIC plumb
echo "$MYIP $MYHOST $MYHOST.local" >> /etc/hosts

Save nic settings in file:

HOSTNIC=/etc/hostname.$MYNIC
echo "$MYIP" > $HOSTNIC
echo "netmask $MYSUBMASK broadcast + up" >> $HOSTNIC

Manually set IP:

ifconfig $MYNIC $MYIP netmask $MYSUBMASK up

Add new route:

route add $MYNET $MYIP -interface -ifp $MYNIC

Check that your IP is set:

ifconfig -a $MYNIC
