If your solaris machine is not configured for DHCP, you need to set up the files

/etc/resolv.conf and /etc/defaultrouter.

/etc/defaultrouter should contain the IP number of your gateway.

/etc/resolv.conf should contain up to 3 lines looking like

nameserver 212.100.224.80
nameserver 216.220.40.243

 

Once DNS is pointing to the right servers you can run nslookups running this command:

 /usr/sbin/nslookup google.com
