You are logged in to a Solaris 11 system as user jack. You issue the following sequence of commands:
Identify two correct statements.
Oracle Solaris provides predefined rights profiles. These profiles, listed in the /etc/security/prof_attr, can be assigned by the root role to any account. The root role is assigned all privileges and all authorizations, so can perform all tasks, just as root can when root is a user.
To perform administrative functions, you open a terminal and switch the user to root. In that terminal, you can then perform all administrative functions.
$ su - root
Password: Type root password
#
When you exit the shell, root capabilities are no longer in effect.
In a default standalone installation of Oracle Solaris 11, what is the default minimum length in characters of a user password, and where is the minimum password length defined?
By default, the passwd command assumes a minimum length of six characters. You can use the PASSLENGTH default in the /etc/defaults/passwd files to change that by setting the minimum number of characters that a user's password must contain to some other number.
To assist in examining and debugging running processes, Solaris 11 has a utility that returns pro arguments and the names and values of environment variables.
What is the name of this utility?
The pargs utility examines a target process or process core file and prints arguments, environment variables and values, or the process auxiliary vector.
The line
set noexec_user_stack= l
should be added to the /etc/system file to prevent an executable stack while executing user programs. What is the purpose of this?
How to Disable Programs From Using Executable Stacks
Purpose: Prevent executable stack from overflowing.
You must be in the root role.
Edit the /etc/system file, and add the following line:
set noexec_user_stack=1
Reboot the system.
# reboot
In an effort to reduce storage space on your server, you would like to eliminate duplicate copies of data in your server's ZFS file systems.
How do you specify that pool1/data should not contain duplicate data blocks (redundant data) on write operations?
ZFS Deduplication Property
Solaris Express Community Edition, build 129: In this Solaris release, you can use the deduplication 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.
You can enable this property as follows:
# zfs set dedup=on tank/home
