Here is a quick and dirty shell script to configure a single interface OmniOS Guest:

root@ns1:~# cat addr.sh
#!/bin/bash
read -p “hostname:” hn
hostname $hn
echo $hn > /etc/nodename
echo “domain csuohio.edu” > /etc/resolv.conf
read -p “dns servers up to 3 separated by commas:” dns
echo $dns | awk -F’,’ ‘{print “nameserver ” $1}’ >> /etc/resolv.conf
echo $dns | awk -F’,’ ‘{print “nameserver ” $2}’ >> /etc/resolv.conf
echo $dns | awk -F’,’ ‘{print “nameserver ” $3}’ >> /etc/resolv.conf

e=`dladm show-link -p -o link`
if [ $e ]; then
ipadm create-if $e
adr=`ipadm show-addr -p -o addrobj | grep $e`
if [ $adr ]; then
ipadm delete-addr $adr
fi
read -p “IP address:” ipadr
read -p “subnet bits:” bits
ipadm create-addr -T static -a $ipadr/$bits $e/v4static
ipadm show-addr
gtwy=`netstat -rn | awk ‘$1==”default” {print $2}’`
route -p delete default $gtwy
read -p “gateway:” gtwy
route -p add default $gtwy
echo $ipadr”\t”$hn >>/etc/hosts
fi
