240 IBM Systems Director Management Console: Introduction and Overview
Deleting users
To remove a user using the command line, run smcli rmuser (Example 9-14).
Example 9-14 Deleting a user with the smcli rmuser command
sysadmin@sdmca:~> smcli rmuser -u newUser
User deleted successfully
In the GUI, there is a link at the bottom of the Welcome  Settings page that
explains how to remove a user.
9.2 Network configuration
This section describes the network configuration of the SDMC with the GUI and
the CLI and how to test the network configuration.
The connection between the SDMC and its managed systems can be
implemented either as a private or open network (see Figure 2-1 on page 18).
The term open refers to any general, public network that contains elements other
than SDMCs and service processors (FSP) that is not isolated behind a firewall.
In a private service network, however, the only elements on the physical network
are the SDMC and the service processors of the managed systems. In addition,
the SDMC provides Dynamic Host Configuration Protocol (DHCP) services on
that network, which allow it to automatically discover and assign IP configuration
parameters to those service processors. You can configure the SDMC to select
one of several different address ranges to use for this DHCP service, so that the
addresses provided to the service processors do not conflict with addresses
used on the other networks to which the HMC is connected. The DHCP services
allow the elements on the private service network to be automatically configured
and detected by the SDMC, while at the same time preventing address conflicts
in the network.
On a private network, therefore, all of the elements are controlled and managed
by the SDMC. The SDMC also acts as a functional firewall, isolating that private
network from any of the open networks to which the SDMC is also attached. The
SDMC does not allow any IP forwarding; clients on one network interface of the
SDMC cannot directly access elements on any other network interface.
