NAME

 sysidcfg - system identification configuration file

DESCRIPTION

 

When a diskless client boots for the first time or a system installs over the network, the booting software tries to obtain configuration information about the system (such as the system's root password or name service) from, first, a sysidcfg file and then the name service databases. If the booting software cannot find the information, it prompts the user for it. Like the name service databases, the sysidcfg file can be used to avoid the user prompts and provide a totally hands-off booting process.

The sysidcfg file preconfigures information through a set of keywords. You can specify one or more of the keywords to preconfigure as much information as you want. Each set of systems (one or more) that has unique configuration information must have its own sysidcfg file. For example, you can use the same sysidcfg file to preconfigure the time zone for multiple systems if you want all the systems to have the same time zone configured. However, if you want to preconfigure a different root password for each of those systems, then each system would need its own sysidcfg file.

Where To Put the sysidcfg File

 

The sysidcfg file can reside on a shared NFS network directory or the root directory on a UFS or PCFS diskette in the system's diskette drive. If you put the sysidcfg file on a shared NFS network directory, you have to use the -p option of the add_install_client(1M) command (see install_scripts(1M)) to specify where the system being installed can find the sysidcfg file. If you put the sysidcfg file on a diskette, you need to make sure the diskette is in the system's diskette drive when the system boots (on IA systems, the sysidcfg file should reside on the Solaris Device Configuration Assistant diskette).

Only one sysidcfg file can reside in a directory or diskette. If you are creating more than one sysidcfg file, they must reside in different directories or diskettes.

Keyword Syntax Rules

 

The following rules apply to the keywords in a sysidcfg file:

  • Keywords can be in any order
  • Keywords are not case-sensitive
  • Keyword values can be optionally enclosed in single (') or double (") quotes
  • Only the first instance of a keyword is valid; if you specify the same keyword more than once, the first keyword specified will be used.

Keywords - All Platforms

 

The following keywords apply to both SPARC and IA platforms.

Name Service, Domain Name, Name Server

Naming-related keywords are as follows:

 
name_service=NIS,NIS+,LDAP,DNS,NONE

For the NIS and NIS+ keywords, the options are:

 
domain_name=domain_name
name_server=hostname(ip_address)

The following is an example NIS entry:

 
name_service=NIS 
{domain_name=west.arp.com name_server=timber(129.221.2.1)}

For NIS+, the example is identical to the one above, except for the replacement of the keyword NIS by NIS+.

For DNS, the syntax is:

 
domain_name=domain_name; name_server=ip_address, ... ; 
search=domain_name, ...

You can have a maximum of three IP addresses and six domain names. The total length of a search entry cannot exceed 250 characters. The following is an example DNS entry:

 
name_service=DNS
{domain_name=west.arp.com
name_server=10.0.1.10,10.0.1.20
search=arp.com,east.arp.com}

For LDAP, the syntax is:
 
domain_name=domain_name;
profile=profile_name;
profile_server=ip_address 

The following is an example LDAP entry:

 
name_service=LDAP
{domain_name=west.arp.com
profile=default
profile_server=129.221.2.1}

Choose only one value for name_service. Include either, both, or neither of the domain_name and name_server keywords, as needed. If no keywords are used, omit the curly braces.

Network Interface, Hostname, IP address, Netmask, DHCP, IPv6, Default Route

Network-related keywords are as follows:

 
network_interface=NONE, PRIMARY, value

If you are using DHCP, the options for PRIMARY and value are:

 
dhcp; protocol_ipv6=yes_or_no

For example:

 
network_interface=primary {dhcp protocol_ipv6=yes}

If you are not using DHCP, the options for PRIMARY and value are:

 
hostname=host_name;
ip_address=ip_address;
netmask=netmask;
protocol_ipv6=yes_or_no
default_route=ip_address (IPv4 address only)

For example:

 
network_interface=le0
{hostname=feron
ip_address=129.222.2.7
netmask=255.255.0.0
protocol_ipv6=no
default_route=129.222.2.1}

Choose only one value for network_interface. Include any combination or none of the hostname, ip_address, netmask, and default_route keywords, as needed. If you do not use any of these keywords, omit the curly braces.

protocol_ipv6 and default_route are optional; you do not need to specify them. default_route accepts only an IPv4 address.

Root Password

The root password keyword is root_password. Possible values are encrypted from /etc/shadow. Syntax is:

 
root_password=encrypted_password

Security Policy

The security--related keyword is security_policy. It has the following syntax:

 
security_policy=kerberos, NONE

The kerberos keyword has the following options:

 
{default_realm=FQDN admin_server=FQDN kdc=FQDN1, FQDN2, FQDN3}

where FQDN is a fully qualified domain name. An example of the security_policy keyword is as follows:

 
security_policy=kerberos {default_realm=Yoursite.COM
admin_server=krbadmin.Yoursite.COM
kdc=kdc1.Yoursite.COM, kdc2.Yoursite.COM}

You can list a maximum of three key distribution centers (KDCs) for a security_policy keyword. At least one is required.

Language in Which to Display the Install Program

The system-location keyword is system_locale. It has the following syntax:

 
system_locale=locale

where locale is /usr/lib/locale.

Terminal Type

The terminal keyword is terminal. It has the following syntax:

 
terminal=terminal_type

where terminal_type is a value from /usr/share/lib/terminfo/*.

Timezone Information

The timezone keyword is timezone. It has the following syntax:

 
timezone=timezone

where timezone is a value from /usr/share/lib/zoneinfo/*.

Date and Time

The time server keyword is timeserver. It has the following syntax:

 
timeserver=localhost
timeserver=hostname
timeserver=ip_address

If you specify localhost as the time server, the system's time is assumed to be correct. If you specify the hostname or ip_address (if you are not running a name service) of a system, that system's time is used to set the time.

Keywords -- IA Platform

 

The following keywords apply only to IA platforms. For all these keywords, use kdmconfig -d to create or append to the sysidcfg file. See kdmconfig(1M)

Monitor type
The monitor--related keyword is monitor. The syntax is:

 
monitor=monitor_type

Keyboard language, keyboard layout
The keyboard--language keyword is keyboard. The syntax is:

 
keyboard=keyboard_language {layout=value}

Graphics card, color depth, display resolution, screen size
The display-related keywords are display, size, depth, and resolution. The syntax is:

 
display=graphics_card {size=screen_size
depth=color_depth resolution=screen_resolution}

Pointing device, number of buttons, IRQ level
The mouse-related keywords are pointer, nbuttons, and irq.

 
pointer=pointing_device {nbuttons=number_buttons
irq=value}

EXAMPLES

 Example 1. Sample sysidcfg files
 

The following example is a sysidcfg file for a group of SPARC systems to install over the network. (The host names, IP addresses, and netmask of these systems have been preconfigured by editing the name service.) Because all the system configuration information has been preconfigured, an automated installation can be created by using a custom JumpStart profile.

 
system_locale=en_US
timezone=US/Central
timeserver=localhost
terminal=sun-cmd
name_service=NIS {domain_name=marquee.central.sun.com
                  name_server=connor(129.152.112.3)}
root_password=m4QPOWNY
system_locale=C
security_policy=kerberos 
    {default_realm=Yoursite.COM 
     admin_server=krbadmin.Yoursite.COM
     kdc=kdc1.Yoursite.COM, kdc2.Yoursite.COM}

The following example is a sysidcfg file created for a group of IA systems to install over the network that all have the same keyboard, graphics cards, and pointing devices. The device information (keyboard, display, and pointer) was captured from running kdmconfig -d (see kdmconfig(1M)). In this example, users would see only the prompt to select a language (system_locale) for displaying the rest of the Solaris installation program.

 
keyboard=ATKBD {layout=US-English}
display=ati {size=15-inch}
pointer=MS-S
timezone=US/Central
timeserver=connor
terminal=AT386
name_service=NIS {domain_name=marquee.central.sun.com
                  name_server=connor(129.152.112.3)}
root_password=URFUni9
security_policy=none
