smdiskless(1M) System Administration Commands smdiskless(1M)NAMEsmdiskless - manage diskless client support for a server
SYNOPSIS
/usr/sadm/bin/smdiskless subcommand [ auth_args] -− [subcommand_args]
DESCRIPTION
The smdiskless command manages diskless client support for a server.
smdiskless subcommands are:
add Adds a new diskless client to a server. There are two
usages for this command. The user can either specify
all the optional arguments directly on the command
line, or provide a sysidcfg(4) formatted file as input.
A future enhancement will allow specifying both a
sysidcfg(4) formatted file and optional arguments,
which will override the values in the sysidcfg(4) file.
delete Deletes an existing diskless client from the system
databases and removes any server support associated
with the host, depending on the os_server type.
list Lists existing diskless clients served by os_server.
modify Modifies the specified attributes of the diskless
client os_server.
OPTIONS
The smdiskless authentication arguments, auth_args, are derived from
the smc(1M) arg set and are the same regardless of which subcommand you
use. The smdiskless command requires the Solaris Management Console to
be initialized for the command to succeed (see smc(1M)). After reboot‐
ing the Solaris Management Console server, the first Solaris Management
Console connection might time out, so you might need to retry the com‐
mand.
The subcommand-specific options, subcommand_args, must come after the
auth_args and must be separated from them by the -− option.
auth_args
The valid auth_args are -D, -H, -l, -p, -r, and -u; they are all
optional. If no auth_args are specified, certain defaults will be
assumed and the user may be prompted for additional information, such
as a password for authentication purposes. These letter options can
also be specified by their equivalent option words preceded by a double
dash. For example, you can use either -D or -−domain.
Note - smdiskless supports the --auth-data file option, which enables
you to specify a file the console can read to collect authenti‐
cation data. See smc(1M) for a description of this option.
-D | -−domain domain
Specifies the default domain that you want to manage. The syntax of
domain is type:/host_name/domain_name, where type is nis, nis+,
dns, ldap, or file; host_name is the name of the machine that
serves the domain; and domain_name is the name of the domain you
want to manage. (Note: Do not use nis+ for nisplus.)
If you do not specify this option, the Solaris Management Console
assumes the file default domain on whatever server you choose to
manage, meaning that changes are local to the server. Toolboxes can
change the domain on a tool-by-tool basis; this option specifies
the domain for all other tools.
-H | -−hostname host_name:port
Specifies the host_name and port to which you want to connect. If
you do not specify a port, the system connects to the default port,
898. If you do not specify host_name:port, the Solaris Management
Console connects to the local host on port 898. You may still have
to choose a toolbox to load into the console. To override this
behavior, use the smc(1M)-B option, or set your console prefer‐
ences to load a "home toolbox" by default.
-l | -−rolepassword role_password
Specifies the password for the role_name. If you specify a
role_name but do not specify a role_password, the system prompts
you to supply a role_password. Passwords specified on the command
line can be seen by any user on the system, hence this option is
considered insecure.
-p | -−password password
Specifies the password for the user_name. If you do not specify a
password, the system prompts you for one. Passwords specified on
the command line can be seen by any user on the system, hence this
option is considered insecure.
-r | -−rolename role_name
Specifies a role name for authentication. If you do not specify
this option, no role is assumed.
-u | -−username user_name
Specifies the user name for authentication. If you do not specify
this option, the user identity running the console process is
assumed.
-−
This option is required and must always follow the preceding
options. If you do not enter the preceding options, you must still
enter the -− option.
subcommand_args
Note: Descriptions and other arg options that contain white spaces must
be enclosed in double quotes.
· For subcommand add:
-h
(Optional) Displays the command's usage statement.
-i IP_address
Specifies the IP address for the host in the form of
172.16.200.1.
-e ethernet_addr
Specifies the Ethernet address.
-n host
Specifies the client name.
-o os_server
(optional) Specifies the name of the host where the OS service
filesystems reside. If this option is not specified, the host
will be the same as that specified in the smc(1M)-D option.
This option is useful in the event that the name service
server and the OS server are not the same machine.
-x os=platform
Specifies the operating system. The syntax for platform is as
follows:
instruction_set.implementation.Solaris_version
where
· instruction_set is one of sparc or i386
· implementation is the implementation architecture, that
is, i86pc and sun4u.
· version is the Solaris version number. The supported ver‐
sion numbers are 2.6, 2.7 (for Solaris 7), 8, 9, and 10.
Examples are:
sparc.sun4u.Solaris_8
-x root=pathname
(Optional) Specifies the absolute path of the directory in
which to create the root directory for diskless clients. The
default (and recommended) pathname is
/export/root/client_name.
-x swap=pathname
(Optional) Specifies the absolute path of the directory in
which to create the swap file for diskless clients. The
default (and recommended) pathname is
/export/swap/client_name.
-x swapsize=size
(Optional) Specifies the size, in megabytes, of the swap file
for diskless clients. The default swap size is 24M.
-x dump=pathname
(Optional) Specifies the absolute path of the dump directory
for diskless clients. The default (and recommended) pathname
is /export/dump/client_name.
-x dumpsize=size
(Optional) Specifies the size, in megabytes, of the dump file
for diskless clients. The default swap size is 24M.
-x pw=Y
(Optional) Prompts for the system's root password. The default
is not to prompt.
The following options are used to configure workstations on first
boot by sysidtool(1M). They can either be specified on the command
line, or in a sysidcfg(4) formatted file. Note: Use the sysid‐
cfg(4) file to:
· Add a DNS client.
· Specify use of the LDAP name service.
· Specify a security policy.
The keywords and functions supported by sysidtool and sysidcfg
vary among Solaris releases. Consult the man pages for your oper‐
ating system release (uname -r) to determine the level of support
available.
-x tz=timezone
(Optional) Specifies the path of a timezone file, relative to
/usr/share/lib/zoneinfo. The default is the server's timezone.
-x ns=NIS | NIS+ | NONE
(Optional) Specifies the client's nameservice. This is one of
NIS, NIS+, or NONE . Use a sysidcfg(4) file to specify DNS or
LDAP. The default ns value is NONE, which results in the use
of the files source in nsswitch.conf. See nsswitch.conf(4) for
a description of the files source.
-x nameserver=hostname
(Optional) Specifies the nameserver's hostname. The default is
the server's nameserver.
-x domain=domain
(Optional) Specifies the client's domain. The default is the
server's domain.
-x nameserver_ipaddress=ip_address
(Optional) Specifies the nameserver's IP address.
-x netmask=ip_address
(Optional) Specifies the client's IP address netmask. The
default is the server's netmask.
-x locale=locale
(Optional) Specifies the client's system locale. The default
is the C locale.
-x terminal=term
(Optional) Specifies the workstation's terminal type, typi‐
cally, sun or xterms.
-x passwd=root_password
(Optional) Specifies the system's root password. The default
is no password.
-x sysidcfg=path_to_sysidcfg_file
(Optional) Specifies the file to be placed in the /etc direc‐
tory of the diskless client. On first boot, /etc/.UNCONFIGURED
exists and sysidtool(1M) will run. If a file called
/etc/sysidcfg exists, sysidtool(1M) reads this file and uses
the information for system configuration.
· For subcommand delete:
-h
(Optional) Displays the command's usage statement.
-n host
Specifies the hostname of the diskless client to delete. This
host is deleted from relevant tables and OS Services for this
client are deleted.
-o os_server
(Optional) Specifies the name of the host where the OS service
filesystems reside. If this option is not specified, the host
will be the same as that specified in the smc(1M)-D option.
This option is useful in the event that the name service
server and the OS server are not the same machine.
· For subcommand list:
-h
(Optional) Displays the command's usage statement.
-o os_server
(Optional) Specifies the name of the host where the OS service
filesystems reside. If this option is not specified, the host
will be the same as that specified in the smc(1M)-D option.
This option is useful in the event that the name service
server and the OS server are not the same machine.
· For subcommand modify:
-e ethernet_addr
Changes the specified diskless client's ethernet address to
ethernet_addr.
-h
(Optional) Displays the command's usage statement.
-n host
Specifies the host name of the diskless client to modify.
-o os_server
(Optional) Specifies the name of the host where the OS service
filesystems reside. If this option is not specified, the host
will be the same as that specified in the smc(1M)-D option.
This option is useful in the event that the name service
server and the OS server are not the same machine.
-x tz=timezone
(Optional) Changes the specified diskless client's timezone.
EXAMPLES
Example 1: Creating a new diskless client
The following command adds a new diskless client named client1 which
will run Solaris 10 on a sun4u machine:
example% /usr/sadm/bin/smdiskless add -- -i 172.16.200.1 \
-e 8:0:11:12:13:14 -n client1 -x os=sparc.sun4u.Solaris_10 \
-x root=/export/root/client1 -x swap=/export/swap/client1 \
-x swapsize=32 -x tz=US/Eastern -x locale=en_US
Example 2: Deleting an existing diskless client
The following command deletes the diskless client named client1 from
the OS server named osserver, where the OS server is using NIS+ and the
NIS+ server is nisplusserve:
example% /usr/sadm/bin/smdiskless delete \
-D nisplus:/nisplusserver/my.domain.com -- \
-o osserver -n client1
Example 3: Listing the diskless clients served by a host
The following command lists the diskless clients running on the OS
server, osserver:
example% /usr/sadm/bin/smdiskless list -D file:/osserver/osserver -- \
-o osserver
Example 4: Modifying the attributes of the diskless client host
The following command modifies the ethernet address for the client
named client1 on the OS server, osserver, to be 8:0:11:12:13:15:
example% /usr/sadm/bin/smdiskless modify -D file:/osserver/osserver -- \
-o osserver -n client1 -e 8:0:11:12:13:15
