claccess(1CL) Sun Cluster Maintenance Commands claccess(1CL) NAME
claccess - manage Sun Cluster access policies for nodes SYNOPSIS
/usr/cluster/bin/claccess -V /usr/cluster/bin/claccess [subcommand] -? /usr/cluster/bin/claccess subcommand [options] -v [hostname[,...]] /usr/cluster/bin/claccess allow -h hostname[,...] /usr/cluster/bin/claccess allow-all /usr/cluster/bin/claccess deny -h hostname[,...] /usr/cluster/bin/claccess deny-all /usr/cluster/bin/claccess list /usr/cluster/bin/claccess set -p protocol=authprotocol /usr/cluster/bin/claccess show DESCRIPTION
The claccess command controls the network access policies for machines that attempt to access the cluster configuration. The claccess com- mand has no short form. The cluster maintains a list of machines that can access the cluster configuration. The cluster also stores the name of the authentication protocol that is used for these nodes to access the cluster configuration. When a machine attempts to access the cluster configuration, for example when it asks to be added to the cluster configuration (see cln- ode(1CL)), the cluster checks this list to determine whether the node has access permission. If the node has permission, the node is authenticated and allowed access to the cluster configuration. You can use the claccess command for the following tasks: o To allow any new machines to add themselves to the cluster configuration and remove themselves from the cluster configuration o To prevent any nodes from adding themselves to the cluster configuration and removing themselves from the cluster configuration o To control the authentication type to check You can use this command only in the global zone. The general form of the claccess command is as follows: claccess [subcommand] [options] You can omit subcommand only if options specifies the -? option or the -V option. Each option of this command has a long form and a short form. Both forms of each option are provided with the description of the option in the "OPTIONS" section of this man page. SUBCOMMANDS
The following subcommands are supported: allow Allows the specified machine or machines to access the cluster configuration. Users other than superuser require solaris.cluster.modify role-based access control (RBAC) authorization to use this subcommand. See rbac(5). See also the description of the deny and the allow-all subcommands. allow-all Allows all machines to add themselves to access the cluster configuration. Users other than superuser require solaris.cluster.modify RBAC authorization to use this subcommand. See rbac(5). See also the description of the deny-all and the allow subcommands. deny Prevents the specified machine or machines from accessing the cluster configuration. Users other than superuser require solaris.cluster.modify RBAC authorization to use this subcommand. See rbac(5). See also the description of the allow and the deny-all subcommands. deny-all Prevents all machines from accessing the cluster configuration. No access for any node is the default setting after the cluster is configured the first time. Users other than superuser require solaris.cluster.modify RBAC authorization to use this subcommand. See rbac(5). See also the description of the allow-all and the deny subcommands. list Displays the names of the machines that have authorization to access the cluster configuration. To see the authentication protocol as well, use the show subcommand. Users other than superuser require solaris.cluster.read RBAC authorization to use this subcommand. See rbac(5). set Sets the authentication protocol to the value that you specify with the -p option. By default, the system uses sys as the authentica- tion protocol. See the -p option in "OPTIONS". Users other than superuser require solaris.cluster.modify RBAC authorization to use this subcommand. See rbac(5). show Displays the names of the machines that have permission to access the cluster configuration. Also displays the authentication protocol. Users other than superuser require solaris.cluster.read RBAC authorization to use this subcommand. See rbac(5). OPTIONS
The following options are supported: -? --help Displays help information. When you use this option, no other processing is performed. You can specify this option without a subcommand or with a subcommand. If you specify this option without a subcommand, the list of subcommands of this command is displayed. If you specify this option with a subcommand, the usage options for the subcommand are dis- played. -h hostname --host=hostname --host hostname Specifies the name of the node being granted or denied access. -p protocol=authprotocol --authprotocol=authentication_protocol --authprotocol authentication_protocol Specifies the authentication protocol that is used to check whether a machine has access to the cluster configuration. Supported protocols are des and sys (or unix). The default authentication type is sys, which provides the least amount of secure authentication. For more information on adding and removing nodes, see Adding a Cluster Node in Sun Cluster System Administration Guide for Solaris OS. For more information on these authentication types, see Chapter 16, Using Authentication Services (Tasks), in System Administration Guide: Security Services. -V --version Displays the version of the command. Do not specify this option with subcommands, operands, or other options. The subcommands, operands, or other options are ignored. The -V option displays only the version of the command. No other processing is performed. -v --verbose Displays verbose information to standard output (stdout). EXIT STATUS
If the command is successful for all specified operands, it returns zero (CL_NOERR). If an error occurs for an operand, the command pro- cesses the next operand in the operand list. The returned exit code always reflects the error that occurred first. The following exit codes can be returned: 0 CL_NOERR No error The command that you issued completed successfully. 1 CL_ENOMEM Not enough swap space A cluster node ran out of swap memory or ran out of other operating system resources. 3 CL_EINVAL Invalid argument You typed the command incorrectly, or the syntax of the cluster configuration information that you supplied with the -i option was incorrect. 6 CL_EACCESS Permission denied The object that you specified is inaccessible. You might need superuser or RBAC access to issue the command. See the su(1M) and rbac(5) man pages for more information. 18 CL_EINTERNAL Internal error was encountered An internal error indicates a software defect or other defect. 39 CL_EEXIST Object exists The device, device group, cluster interconnect component, node, cluster, resource, resource type, or resource group that you specified already exists. EXAMPLES
Example 1 Allow a New Host Access The following claccess command allows a new host to access the cluster configuration. # claccess allow -h phys-schost-1 Example 2 Set the Authentication Type The following claccess command sets the current authentication type to des. # claccess set -p protocol=des Example 3 Deny Access to All Hosts The following claccess command denies all hosts access to the cluster configuration. # claccess deny-all ATTRIBUTES

The superuser user can run all forms of this command. Any user can run this command with the following subcommands and options: o -? option o -V option To run this command with other subcommands, users other than superuser require RBAC authorizations.
