Let's shut down the system:


admin@nex1:/export$ su
Password:
root@nex1:/export# shutdown

srv-5:~ usr4$

The system goes into single user mode:

nexenta

Logging in and entering init 3 allowed us to SSH to the box, but the web interface was still down:

nexenta

Ahhh... but init 5 will stop the system:

srv-5:~ usr4$ ssh admin@192.168.2.43
