smtnrhdb(1M)

Name

smtnrhdb– manage entries in the tnrhdb database

Synopsis

/usr/sadm/bin/smtnrhdb subcommand [auth_args] -- subcommand_args]

Description

The smtnrhdb command adds, modifies, deletes, and lists entries in the tnrhdb database.

The tnrhdb database specifies which remote-host template to use for each host, including the local host, in the distributed system. If a host's IP address cannot be matched to some entry in the tnrhdb database, communication with the host is not permitted.

The smtnrhdb command requires the Solaris Management Console to be initialized for the command to succeed (see smc(1M)). After rebooting the Solaris Management Console server, the first smc connection can time out, so you might need to retry the command.

Valid Host Addresses and Wildcards

The trusted network software uses a network “longest prefix of matching bits” mechanism when looking for a host. The software looks first for the IP address of the host. If the software does not find this address, then the software falls back to searching for an IP address with the longest prefix of a matching bit pattern, and so on.

Note –

The actual numeric value of the subnet address or other subnetting information on the system (for example, from the netmasks(4) file) are not considered by this mechanism.

Using the “longest prefix of matching bits” mechanism, an IPv4 address of 0.0.0.0 is a wildcard address with a prefix length of 0 and hence matches any IPv4 address. For more information about prefi x lengths in IPv4 and IPv6 addresses, see System Administration Guide: IP Services.

The smtnrhdb command accepts a hostname, IP address, and wildcard address with as optional prefix as valid addresses. See subcommand_args, below, for the format of valid addresses.

Sub-commands

smtnrhdb subcommands are:

add: Adds a new entry to the tnrhdb database. To add an entry, the administrator must have the solaris.network.host.write and solaris.network.security.write authorizations.
delete: Deletes an entry from the tnrhdb database. To delete an entry, the administrator must have the solaris.network.host.write and solaris.network.security.write authorizations.
list: Lists all entries in the tnrhdb database. To list an entry, the administrator must have the solaris.network.host.read and solaris.network.security.read authorizations.
modify: Modifies an entry in the tnrhdb database. To modify an entry, the administrator must have the solaris.network.host.write and solaris.network.security.write authorizations.

Options

The smtnrhdb authentication arguments, auth_args, are derived from the smc arg set. These arguments are the same regardless of which subcommand you use.

The subcommand-specific options, subcommand_args, must be preceded 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 might 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.

-D | --domain domain

Specifies the default domain that you want to manage. The syntax of domain=type:/host_name/domain_name, where type is dns, ldap, or file; host_name is the name of the server; and domain_name is the name of the domain you want to manage.

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.

-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.

-h: Displays the command's usage statement.
-H hostname: Specifies the name of the host. For the list subcommand, the hostname argument is not specified. This is not required if the ipaddress subcommand argument is specified.
-i ipaddress: Specifies the IP address of the host. This is not required if the hostname subcommand argument is specified. This option is not valid with the -w option.
-n templatename: Specifies the name of an existing template.
-p prefixlen: Specifies the prefix length (in bits) of a wildcard representation of the IP address. The prefix is the left-most portion of the IP address. This option is valid only with the -w option. For example, when the value of -w ipaddress-wildcard is 192.168.0.0, a prefixlen value of 24 indicates that the wildcard matches all addresses on the 192.168.0 network. With a prefixlen of 32, the wildcard 192.168.0.0 matches all addresses on the 192.168.0.0 network.
-w ipaddress-wildcard: Specifies the IP address of the subnet using a wildcard.

One of the following sets of arguments must be specified for subcommand add:

-H hostname -n templatename |
-i ipaddress -n templatename |
-w ipaddress-wildcard -n templatename [ -p prefixlen ] |
-h

One of the following sets of arguments must be specified for subcommand modify:

-H hostname -n templatename |
-i ipaddress -n templatename |
-w ipaddress-wildcard -n templatename [ -p prefixlen ] |
-h

One of the following sets of arguments must be specified for subcommand delete:

-H hostname |
-i ipaddress |
-w ipaddress-wildcard [ -p prefixlen ] |
-h

The subcommand list takes the following argument:
-h

Examples

Example 1 Specifying the Template Name for a Wildcard IP Address

The admin role specifies the template name, cipso_lan, for a series of hosts that use the IP address wildcard 192.168.113.0 on the local file system. Since no authorization arguments were specified, the administrator connects to port 898 of the local host on the local server with the file domain type, which are the defaults. The administrator is prompted for the admin password.

$ usr/sadm/bin/smtnrhdb add -- -w 192.168.113.0 -n cipso_lan

Example 2 Deleting an Entry in the `tnrhdb` Database

The admin role connects to port 898 (which happens to be the default) of the LDAP server and deletes a host entry from the database by specifying its IP address, 192.168.113.8. Since the domain was not specified, the file domain type and local server are used by default. The administrator is prompted for the admin password.

# /usr/sadm/bin/smtnrhdb delete \
-D ldap:/example.domain -i 192.168.113.8

Example 3 Adding a Subnet to the `tnrhdb` Database

The following command adds all the addresses on the 192.168.55.0 subnet, from 192.168.55.1 to 192.168.55.255, to the tnrhdb database:

# /usr/sadm/bin/smtnrhdb add \
-D file:/machine1.ExampleCo.COM/machine1.ExampleCo.COM \
 -- -w 192.168.55.0 -n cipso
Authenticating as user: root
Type /? for help, pressing <enter> accepts the default denoted by [ ]

Example 4 Adding Subnet 192.168.0 to the `tnrhdb` Database

The following command adds all the addresses on the 192.168.0 subnet, from 192.168.0.1 to 192.168.0.255 to the tnrhdb database. The prefix, 24, indicates that the first 24 bits (192.168.0) are fixed. Only the final zero is a wildcard.

# /usr/sadm/bin/smtnrhdb add \
-D file:/machine1.ExampleCo.COM/machine1.ExampleCo.COM \
 -- -w 192.168.0.0 -p 24 -n cipso

Login to machine1.ExampleCo.COM as user root was successful.
