If you can only connect to the console by logging into the system that is running the console, and then using the URL https://localhost:6789, the system is using a configuration that prevents remote access. Starting with the Solaris 10 11/06 release, you can enable remote access only to the console, while leaving the other access restrictions in place, by using the following procedure:
Become superuser or assume an equivalent role on the system where the console is running.
Roles contain authorizations and privileged commands. For more information about roles, see Configuring RBAC (Task Map) in System Administration Guide: Security Services.
Set a property to allow the console server to respond to network requests and restart the console server.
# svccfg -s svc:/system/webconsole setprop options/tcp_listen = true # smcwebserver restart
