Hi dear,
once if you installed solaris and if you connect a router that delivering dhcp dynamically, sure solaris will accept the incoming dhcp connections.
i tried this myself .
i think may be your ethernet is not supported by solaris , first you check your ethernet driver is installed properly.
to check that.
ifconfig -a
it will list down the ethernet properties such as ip address, subnet and broadcast address. ( with the interface name )
if you find only loopback address without any ip and broadcast , then pretty sure your ethernet is not installed ...
find a suitable ethernet card for solaris.
Try commad prtdiag to ensure that ethernet driver is installed properly. prtdiag will show all the hardware details installed.
Hope this help you.
Thanks & Regards
Vijay,
