sysidcfg(4) File Formats sysidcfg(4)NAMEsysidcfg - 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.
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 condi‐
tion, the file is not used.
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 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 spec‐
ify the same keyword more than once, the first keyword spec‐
ified is used. The network_interface keyword is exempt from
this rule.
Keywords - All Platforms
The following keywords apply to both SPARC and x86 platforms.
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 fol‐
lowing 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;
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 nei‐
ther of the domain_name and name_server keywords, as needed. If no key‐
words 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 nam‐
ing service configuration.
For example:
nfs4_domain=example.com
...hard codes the value used by the nfsmapid(1M) daemon to be exam‐
ple.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 services, 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
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 config‐
ure them all in the sysidcfg file by defining multiple network_inter‐
face 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 pri‐
mary 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:
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 secu‐
rity_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 syn‐
tax:
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/*or, where time‐
zone 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="<GMT+8>+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 syntax:
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 preconfigured by editing the name service.
Because all the system configuration information has been preconfig‐
ured, an automated installation can be achieved by using this sysidcfg
file in conjunction with a custom JumpStart profile.
keyboard=US-English
system_locale=en_US
timezone=US/Central
timeserver=localhost
terminal=sun-cmd
name_service=NIS {domain_name=marquee.central.example.com
name_server=connor(172.16.112.3)}
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 x86
systems to install over the network that all have the same keyboard,
graphics cards, and pointing devices. 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=US-English
display=ati {size=15-inch}
pointer=MS-S
timezone=US/Central
timeserver=connor
terminal=AT386
name_service=NIS {domain_name=marquee.central.example.com
name_server=connor(172.16.112.3)}
root_password=URFUni9
security_policy=none
