In other UNIX operating systems, I have used the /etc/dhclient.conf option:
send host-name "hostname"
to register the hostname on the DNS through the DHCP server. However I can't find any similar option or file in Solaris 11.
Note that I have discovered the "REQUEST_HOSTNAME" option on /etc/default/dhcpagent but I believe that it functions other purpose.
Any help would be much appreciated.
