Check DNS
* (A) Check whether DNS is configured on your client by verifying that a non-empty
/etc/resolv.conf file exists.
* (F) If /etc/resolv.conf does not exist or is empty, check that your DHCP server is providing DNS server information to the client:
# /sbin/dhcpinfo DNSserv
If this command returns nothing, the DHCP server is not set up to provide DNS server information to the client. Contact your DHCP administrator to correct this problem.
* (B) If an /etc/resolv.conf file exists and is properly configured, check for the following possible problems and contact your system administrator for resolution:
** The DNS server might not be resolving your IPS repository server name.
** No default route to reach the DNS server exists.

zfs snapshot [-r] [-o property=value] ... filesystem@snapname|volume@snapname Creates a snapshot with the given name. All previous modifications by successful system calls to the file system are part of the snapshot
zfs clone [-p] [-o property=value] ... snapshot filesystem|volume Creates a clone of the given snapshot.
Note:
Because snapshots are fast and low overhead, they can be used extensively without great concern for system performance or disk use .
With ZFS you can not only create snapshot but create a clone of a snapshot.
A clone is a writable volume or file system whose initial contents are the same as the dataset from which it was created. As with snapshots, creating a clone is nearly instantaneous, and initially consumes no additional disk space. In addition, you can snapshot a clone.
A clone is a writable volume or file system whose initial contents are the same as the original dataset. As with snapshots, creating a clone is nearly instantaneous, and initially consumes no additional space.
Clones can only be created from a snapshot. When a snapshot is cloned, it creates an implicit dependency between the parent and child.

The content of the /etc/shadow document indicates that the newuser account has no password.
We need to add a password.
The passwd utility is used to update user's authentication token(s). D: Here the user account already exist. There is no need to create it.
When invoked without the -D option, the useradd command creates a new user account using the values specified on the command line plus the default values from the system. Depending on command line options, the useradd command will update system files and may also create the new user's home directory and copy initial files.

C: Here the wildcard character ? is used (Matches any single character). file1 and file2 will be copied into dir1
F: the two files file1 and file2 are copied into directoy dir1. Note: cp - copy files and directories
Copy SOURCE to DEST, or multiple SOURCE(s) to DIRECTORY.
Cp has three principal modes of operation. These modes are inferred from the type and count of arguments presented to the program upon invocation.
* When the program has two arguments of path names to files, the program copies the contents of the first file to the second file, creating the second file if necessary.
* When the program has one or more arguments of path names of files and following those an argument of a path to a directory, then the program copies each source file to the destination directory, creating any files not already existing.
* When the program's arguments are the path names to two directories, cp copies all files in the source directory to the destination directory, creating any files or directories needed. This mode of operation requires an additional option flag, typically r, to indicate the
recursive copying of directories. If the destination directory already exists, the source is copied into the destination, while a new directory is created if the destination does not exist.

There are two ways to configure the network configuration: automatic or manual.
In the exhibit we see that DHCP has been used used. This indicates an automatic network configuration.

n Oracle Solaris 11, you can use the deduplication (dedup) property to remove redundant data from your ZFS file systems. If a file system has the dedup property enabled, duplicate data blocks are removed synchronously. The result is that only unique data is stored, and common components are shared between files.

This example shows how to display the default root crontab file.
$ suPassword:
# crontab -l
#ident "@(#)root 1.19 98/07/06 SMI" /* SVr4.0 1.1.3.1 */
#
# The root crontab should be used to perform accounting data collection.
#
#
10 3 * * * /usr/sbin/logadm
15 3 * * 0 /usr/lib/fs/nfs/nfsfind
30 3 * * * [ -x /usr/lib/gss/gsscred_clean ] && /usr/lib/gss/gsscred_clean
#10 3 * * * /usr/lib/krb5/kprop_script slave_kdcs

You can convert a non-redundant storage pool into a redundant storage pool by using the zpool attach command.
Note: zpool attach [-f] pool device new_device
Attaches new_device to an existing zpool device. The existing device cannot be part of a raidz configuration. If device is not currently part of a mirrored configuration, device automatically transforms into a two-way mirror of device and new_device. If device is part of a two-way mirror, attaching new_device creates a three-way mirror, and so on. In either case, new_device begins to resilver immediately.

The first IP address is already in use.

Use the pkg search command to search for packages whose data matches the specified pattern.
Like the pkg contents command, the pkg search command examines the contents of packages. While the pkg contents command returns the contents, the pkg search command returns the names of packages that match the query.

From the content of the /etc/shadow file we get:
* username: jack
* encrypted password: $5$9JFrt54$7JdwmO.F11Zt/ jFeeOhDmnw93LG7Gwd3Nd/cwCcNWFFg
* Last password change (lastchanged): Days since Jan 1, 1970 that password was last changed: 0
* Minimum: The minimum number of days required between password changes i.e. the number of days left before the user is allowed to change his/her password: 15
Maximum: The maximum number of days the password is valid (after that user is forced to change his/her password): 30 Warn : The number of days before password is to expire that user is warned that his/her password must be changed: 3
* Inactive : The number of days after password expires that account is disabled
* Expire : days since Jan 1, 1970 that account is disabled i.e. an absolute date specifying when the login may no longer be used

pkgchk checks the accuracy of installed files or, by using the -l option, displays information about package files. pkgchk checks the integrity of directory structures and files. Discrepancies are written to standard error along with a detailed explanation of the problem.

By default, the pkg info command only lists information about installed packages on the system; however, we can use a similar command to look up information about uninstalled packages, as shown in here:
Example:
Listing Information About an Uninstalled Package
# pkg info -r php-52 Name: web/php-52 Summary: PHP Server 5.2
Description: PHP Server 5.2 Category: Development/PHP State: Not Installed Publisher: solaris
Version: 5.2.17
Build Release: 5.11
Branch: 0.175.0.0.0.1.530
Packaging Date: Wed Oct 12 14:01:41 2011
Size: 44.47 MB
FMRI: pkg://solaris/web/php-52@5.2.17, 5.11-0.175.0.0.0.1.530:20111012T140141Z
Note: pkg info command displays information about packages in a human-readable form. Multiple FMRI patterns may be specified; with no patterns, display information on all
installed packages in the image.
With -l, use the data available from locally installed packages. This is the default.
With -r, retrieve the data from the repositories of the image's configured publishers. Note that you must specify one or more package patterns in this case.

A subnetwork, or subnet, is a logically visible subdivision of an IP network. The practice of dividing a network into two or more networks is called subnetting.
The routing prefix of an address is written in a form identical to that of the address itself. This is called the network mask, or netmask, of the address. For example, a specification of the most-significant 18 bits of an IPv4 address, 11111111.11111111.11000000.00000000, is written as 255.255.192.0.

installadm add-manifest
Associates manifests with a specific install service, thus making the manifests available on the network, independently from creating a service. When publishing a non-default manifest, it is required to associate criteria either via criteria entered on the command line (-c) or via a criteria XML file (-C).

In the Bourne Again, C, Korn, TC, and Z shells, the tilde (~) is used as a shortcut for specifying your home directory.
cd –
It's the command-line equivalent of the back button (takes you to the previous directory you were in).
Note:
To make certain that you are in your home directory, type the cd (change directory) command. This command moves you to your home (default) directory.

B: The Network Status notification icon is only displayed on the desktop if you are using NWAM to automatically configure your network.
C: All online (Wireless)
Indicates all manually enabled connections in the enabled network profile are online and that the required number of connections in the enabled profile group (if such a group exists) are online. The required number is the same as those described for the All online (Wired) status.
Note that at least one online connection is wireless.
