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.
If a syntax error (such as an invalid keyword) is detected
when reading the sysidcfg file, an error message that notes
the position in the file where the error was found is sent
to the console. Under such a condition, the file is not
used.
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 x86 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
o Only the first instance of a keyword is valid; if
you specify the same keyword more than once, the
first keyword specified is used. The
network_interface keyword is exempt from this rule.
Keywords - All Platforms
The following keywords apply to both SPARC and x86 plat-
forms.
Name Service, Domain Name, Name Server
Naming-related keywords are as follows:
name_service=NIS,LDAP,DNS,NONE
For the NIS keyword, 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(172.16.2.1)}
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:
SunOS 5.11 Last change: 10 Dec 2009 2
File Formats sysidcfg(4)
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;
proxy_dn="proxy_bind_dn";
proxy_password=password
The proxy_dn and proxy_password keywords are optional. If
proxy_dn is used, the value must be enclosed in double
quotes.
The following is an example LDAP entry:
name_service=LDAP
{domain_name=west.arp.com
profile=default
profile_server=172.16.2.1
proxy_dn="cn=proxyagent,ou=profile,dc=west,dc=arp,dc=com"
proxy_password=password}
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.
NFS version 4 Default Domain Name
There is only one keyword for specifying the NFSv4 default
domain name:
nfs4_domain=dynamic, value
where value must be a fully qualified domain name, as per
RFC1033 and RFC1035 recommendations. The reserved value
dynamic suppresses the front-end installation prompt. At the
same time, use of dynamic enables the NFSv4 domain to be
derived dynamically, at run time, based on naming service
configuration.
SunOS 5.11 Last change: 10 Dec 2009 3
File Formats sysidcfg(4)
For example:
nfs4_domain=example.com
...hard codes the value used by the nfsmapid(1M) daemon to
be example.com. In contrast, the following example shows how
to set the nfs4_domain variable to the reserved keyword
dynamic:
nfs4_domain=dynamic
The preceding example enables the nfsmapid(1M) daemon to
derive the domain from the system's configured naming ser-
vices, as prescribed in the System Administration Guide:
Network Services.
Network Interface, Hostname, IP address, Netmask, DHCP, Default
Route
Network-related keywords are as follows:
network_interface=NONE, PRIMARY, value
where value is a name of a network interface, for example,
eri0 or hme0.
For the NONE keyword, the options are:
hostname=hostname
For example,
network_interface=NONE {hostname=feron}
For the PRIMARY and value keywords, the options are:
primary (used only with multiple network_interface lines)
dhcp
hostname=hostname
ip_address=ip_address
netmask=netmask
protocol_ipv6=yes | no

File Formats sysidcfg(4)
default_route=ip_address (IPv4 address only)
If you are using the dhcp option, the only other option you
can specify is protocol_ipv6. For example:
network_interface=PRIMARY {dhcp protocol_ipv6=yes}
If you are not using DHCP, you can specify any combination
of the other keywords as needed. If you do not use any of
the keywords, omit the curly braces.
network_interface=eri0 {hostname=feron
ip_address=172.16.2.7
netmask=255.255.255.0
protocol_ipv6=no
default_route=172.16.2.1}
Multiple Network Interfaces
If you have multiple network interfaces on your system, you
can configure them all in the sysidcfg file by defining mul-
tiple network_interface keywords. If you specify multiple
network_interface keywords, you cannot use NONE or PRIMARY
for values. You must specify interface names for all of the
values. To specify the primary interface, use the primary
option value.
For example,
network_interface=eri0 {primary
hostname=feron
ip_address=172.16.2.7
netmask=255.255.255.0
protocol_ipv6=no
default_route=172.16.2.1}
network_interface=eri1 {hostname=feron-b
ip_address=172.16.3.8
netmask=255.255.255.0
protocol_ipv6=no
default_route=172.16.3.1}
Root Password
The root password keyword is root_password. Possible values
are encrypted from /etc/shadow. Syntax is:
SunOS 5.11 Last change: 10 Dec 2009 5
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/*or,
where timezone is an offset-from-GMT style quoted timezone.
Refer to environ(5) for information on quoted timezones. An
example of a quoted timezone is: timezone="+8".
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.
Keyboard Layout
The keyboard keyword is keyboard. It has the following syn-
tax:
keyboard=keyboard_layout
The valid keyboard_layout strings are defined in the
/usr/share/lib/keytables/type_6/kbd_layouts file.
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 precon-
figured by editing the name service. Because all the system
configuration information has been preconfigured, an
automated installation can be achieved by using this
sysidcfg file in conjunction with a custom JumpStart pro-
file.
