Oracle Solaris 1z0-822 Book

Create the etherstub.

global# dladm create-etherstub etherstub

Create a VNIC over the etherstub.

global# dladm create-vnic -l etherstub vnic

Note: Etherstubs / Virtual Switches

The Etherstub is craeated as a dummy device to connect the various virtual NICs. User can imagine etherstub as a Virtual Switch to help visualize the virtual network as a replacement for a physical network where each physical switch is replaced by a virtual switch.

Note:

* The Trusted Solaris environment provides audit classes including:

ss - Change system state

no - Invalid class

lo - Login or logout

* always-audit

Lists the audit classes that are audited for this user. Modifications to the system-wide classes are prefixed by a caret (^). Classes that are added to the system-wide classes are not prefixed by a caret.

never-audit

Lists the audit classes that are never audited for the user, even if these audit events are audited system-wide. Modifications to the system-wide classes are prefixed by a caret (^).

* Process preselection mask – A combination of the system-wide audit mask and the user-specific audit mask, if a user audit mask has been specified. When a user logs in, the login process combines the preselected classes to establish the process preselection mask for the user's processes. The process preselection mask specifies whether events in each audit class are to generate audit records.

The following algorithm describes how the system obtains the user's process preselection mask:

(system-wide default flags + always-audit-classes) - never-audit-classes

* getent user_attr

getent

- get entries from administrative database

getent gets a list of entries from the administrative database specified by database. The information generally comes from one or more of the sources that are specified for the database in /etc/nsswitch.conf.

Example:

The default service model is contract, but may be modified. For this example, we are going to start the service with svc.startd. As a transient service, it will be started once and not restarted by adding the following lines to the manifest:

/>

Note:

svc.startd provides three models of service, which are

* Transient services—These are often configuration services, which require no long-running processes to provide service. Common transient services take care of boot-time cleanup or load configuration properties into the kernel. Transient services are also sometimes used to overcome difficulties in conforming to the method requirements for contract or wait services. This is not recommended and should be considered a stopgap measure.

* Contract services—These are the standard system daemons. They require processes which run forever once started to provide service. Death of all processes in a contract service is considered a service error, which will cause the service to restart.

* Wait services—These services run for the lifetime of the child process, and are restarted when that process exits.
