Configuring a System

You can use the sysconfig configure command to configure or reconfigure an Oracle Solaris instance in a global or non-global zone. This configuration can occur either interactively or non-interactively.

You can use the -c option in the sysconfig configure utility to specify an existing system configuration profile. If the utility is run with that option, then the utility reads the configuration specifications in the existing profile and uses those specifications to configure the system non-interactively.

For example, the following command specifies that the system be configured using the existing configuration profile named myprofile.xml.
```
# sysconfig configure -c myprofile.xml
```
Note - The -c option specifies a profile or a directory of profiles. All profiles must include the .xml file extension.

For information about system configuration (SC) profiles, see Chapter 11, Configuring the Client System.
If the sysconfig configure command is invoked without a specified profile, the SCI Tool is automatically activated.

The SCI Tool supports configuration of freshly installed or unconfigured systems. You can use this tool to provide system configuration for newly created non-global zones or other unconfigured systems. The SCI Tool consists of a series of interactive text panels that ask for configuration information. See How to Reconfigure Using the SCI Tool.

Note - The series screens in the SCI Tool also run automatically as part of a text installation.

Alternately, you can run the SCI Tool to create a new system configuration profile based on the configuration specifications entered in the SCI Tool screens. See Creating a Configuration Profile Using the SCI Tool.

How to Reconfigure Using the SCI Tool

Become the root role.
Note - If you are working in a non-global zone, log into the zone as the root role as follows:
```
# zlogin -C -e ^ ZONENAME
```
Run the sysconfig configure command without specifying a profile.
```
# sysconfig configure
```
The SCI Tool is displayed. The following steps provide instructions for completing the series of interactive panels in the SCI Tool.

Note - Use the function keys to navigate through the SCI Tool panels. You cannot use a mouse. Refer to the function key references on each panel and to the online help as needed.
Continue past the initial Welcome panel.
Enter a name to identify the system on the network.
Specify how the wired ethernet network connection should be configured by selecting one of the following options.
- To use DHCP to configure the network connection, select Automatically.
  The SCI Tool continues to the Time Zone panels.
- To provide networking specifications, select Manually and continue as follows:
  1. If there is more than one interface, select a connection to be configured.
  2. Type the connection settings or accept the default information detected and provided by the SCI Tool.
    Note - The IP address and netmask are required fields. The router is an optional field.
  3. Specify whether the system should use the DNS name service.
  4. If you selected Configure DNS, continue with the following steps.
    1. Type at least one IP address for the DNS server or servers to be used by the system.
    2. Provide at least one domain name to be searched when a DNS query is made.
  5. Specify whether the system should use either the LDAP name services, a NIS name service, or None.
    If you selected DNS in the previous step, LDAP or NIS would be set up as alternate name services in addition to DNS. If you did not select DNS in the previous step, LDAP or NIS would be set up as the only name service.
    If you will be configuring LDAP on the system without an LDAP profile, select None instead of selecting LDAP. Then, configure LDAP manually after the SCI Tool process is complete.
    
    Note - If no network naming services are selected, network names can be resolved by using standard name source files such as /etc/hosts(4). For further information, see the nsswitch.conf(4) man page.
  6. Provide the domain where the system resides for the alternate name service you selected.
    Note - To determine the domain name, check with your system administrator. Or, use the domainname command on a previously-installed system.
  7. If you selected LDAP as the only name service or as an additional name service with DNS, provide the LDAP specifications as follows.
    1. Specify the LDAP profile to be used to configure the LDAP name service on the system.
    2. Type the IP address for the LDAP profile server.
    3. Provide an LDAP search base or accept the default search base.
    4. Specify whether LDAP proxy bind information will be provided.
      Note - If the profile specifies a proxy credential level, and the authentication method is not None, then you must provide the proxy bind information. If you omit that information, LDAP will not be initialized.
    5. If necessary, provide the LDAP proxy bind distinguished name and proxy bind password.
  8. If you selected NIS as the only name service, or as an additional name service with DNS, provide the NIS specifications.
    You can either let the software search for a name server, or you can specify a name server. Select one of the following two choices.
    - Select Find One.
      Note - The software can only find a name server if that server is on the local subnet.
    - Select Specify One and type the name server's host name or IP address in the subpanel.
    After completing the series of networking configuration panels, the SCI Tool displays a series of time zone panels and a Date and Time panel.
- To specify that the network is not configured during the installation, select None.
  The SCI Tool continues to the Time Zone panels.
In the series of time zone panels, select a time zone first, then adjust the date and time to match your local time.
Note - The default is for the GMT time zone to be configured.
Complete the User panel.
You are not required to create a user account. But, you must create a root password.
- If you create a user account in this panel, you need to provide both the user's password and a root password.
  In this case, root will be a role assigned to the user.
  To create a user account, type a username and password. The name must begin with a letter and can only contain letters and numbers.
- If you do not create a user account, you still need to provide a root password.
  In this case, root will be a regular user.
Review the configuration settings.
- If the settings are correct, apply the configuration to the system.
- If the settings are not correct, press the Back key as often as necessary to return to the panel with the incorrect information, make changes, and continue through the panels again.
