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 informa- tion 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 precon- figure 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 direc- tory 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: o Keywords can be in any order o Keywords are not case-sensitive o Keyword values can be optionally enclosed in single (') or double (") quotes SunOS 5.8 Last change: 6 Nov 2000 1 File Formats sysidcfg(4) o 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} SunOS 5.8 Last change: 6 Nov 2000 2 File Formats sysidcfg(4) Choose only one value for name_service. Include either, both, or neither of the domain_name and name_server key- words, 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=129.222.2.1 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: SunOS 5.8 Last change: 6 Nov 2000 3 File Formats sysidcfg(4) 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 syn- tax: 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 syn- tax: 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: SunOS 5.8 Last change: 6 Nov 2000 4 File Formats sysidcfg(4) 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, SunOS 5.8 Last change: 6 Nov 2000 5 File Formats sysidcfg(4) IP addresses, and netmask of these systems have been precon- figured by editing the name service.) Because all the sys- tem 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 cap- tured 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
