The ability to remotely log in to a zone is dependent on the selection of network services that you establish. By default, a non-global zone is installed with the limited networking configuration (/var/svc/profile/generic_limited_net.xml), and only the ssh login is enabled. Logins through rlogin and telnet can be added if needed, either by using the netservices command to switch the zone to the open networking configuration or by enabling the services using SMF.
For more information about changing the network profile or using SMF commands to add services to zones, see Switching the Non-Global Zone to a Different Networking Service Configuration. For more information about login commands, see rlogin(1), ssh(1), and telnet(1)
