Note:

* In Oracle Solaris 11, etherstubs and VNICs are the basic components of network virtualization.

* The VNIC connects the virtual network to the external network. The VNIC also enables the zones to communicate with one another through the virtual switch that is automatically created with the VNIC. For a virtual network to host traffic internally between zones and with the external LAN and the Internet, each zone must have its own interface. Therefore, you must repeat this procedure as many times as the number of zones that will belong to the virtual network.

* Create the etherstub.

# dladm create-etherstub etherstub

Perform this step only if you are creating a private virtual network which you want to restrict from being accessed by external systems.

pkgrepo rebuild [-p publisher ...] -s repo_uri_or_path [--no-catalog] [--no-index]

Discards all catalog, search, and other cached information found in the repository, and then recreates it based on the current contents of the repository.

Incorrect:

Not A: pkg refresh [--full] [publisher ...]

Updates the client's list of available packages and publisher metadata for each publisher specified. If no publishers are specified, the operation is performed for all publishers.

* policy.conf

policy.conf– configuration file for security policy.

The policy.conf file provides the security policy configuration for user-level attributes.

* Example: Modifying Every User's Basic Privilege Set

In this example, the security administrator of a large Sun Ray installation does not want regular users to view the processes of other Sun Ray users. Therefore, on every system that is configured with Trusted Extensions, the root role removes proc_info from the basic set of privileges. The PRIV_DEFAULT setting in the /etc/policy.conf file is uncommented and modified as follows:

PRIV_DEFAULT=basic,!proc_info

* /etc/default/mpathd

Contains default values used by the in.mpathd daemon.

* By default, in.mpathd limits failure and repair detection to IP interfaces that are configured as

part of a named IPMP group. Setting TRACK_INTERFACES_ONLY_WITH_GROUPS to no enables failure and repair detection on all IP interfaces, even if they are not part of a named IPMP group. IP interfaces that are tracked but not part of a named IPMP group are considered to be part of the “anonymous” IPMP group. In addition to having no name, this IPMP group is

special in that its IP interfaces are not equivalent and thus cannot take over for one another in

the event of an IP interface failure. That is, the anonymous IPMP group can only be used for

failure and repair detection, and provides no high-availability or load-spreading

* Set the default scheduler for the system to be the FSS.

# dispadmin -d FSS

* Scheduling Class on a System with Zones Installed

Non-global zones use the default scheduling class for the system. If the system is updated with a new default scheduling class setting, non-global zones obtain the new setting when booted or rebooted.

The preferred way to use FSS in this case is to set FSS to be the system default scheduling class with the dispadmin command.

Precedence Rules

For nfsmapid to work properly, NFS version 4 clients and servers must have the same domain. To ensure matching NFS version 4 domains, nfsmapid follows these strict precedence rules:

1. The daemon first checks the SMF repository for a value that has been assigned to the nfsmapid_domain parameter. If a value is found, the assigned value takes precedence over any other settings. The assigned value is appended to the outbound attribute strings and is compared against inbound attribute strings.

2. If no value has been assigned to nfsmapid_domain, then the daemon checks for a domain name from a DNS TXT RR. nfsmapid relies on directives in the /etc/resolv.conf file that are used by the set of routines in the resolver. The resolver searches through the configured DNS servers for the _nfsv4idmapdomain TXT RR.

3. If no DNS TXT record is configured to provide a domain name, then the nfsmapid daemon uses the value specified by the domain or search directive in the /etc/resolv.conf file, with the directive specified last taking precedence.

4. If the /etc/resolv.conf file does not exist, nfsmapid obtains the NFS version 4 domain name by following the behavior of the domainname command. Specifically, if the /etc/defaultdomain file exists, nfsmapid uses the contents of that file for the NFS version 4 domain. If the /etc/defaultdomain file does not exist, nfsmapid uses the domain name that is provided by the network's configured naming service.

An interface that has been created cannot become a member of an aggregation.

Adding privileges must be performed the global zone administrator by using zonecfg(1M). While adding this functionality, we also added the ability to remove privileges from a zone's limit set.
