Use "pkg search":
% pkg search smbclient
INDEX ACTION VALUE PACKAGE
basename file usr/bin/smbclient pkg:/service/network/sa...@3.6.24-0.175.2.2.0.3.0
and then install it using:
# pkg install service/network/samba
In Solaris 11, we no longer install all or most packages; there is not
not even a way to all packages.
