Explanation:
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.

The line
init core file pattern: /var/core/core.%f.%p
will be used for the non-global process to determine the destination of the dump file.
Note: When a process is dumping core, up to three core files can be produced: one in the per-process location, one in the system-wide global location, and, if the process was running in a local (non-global) zone, one in the global location for the zone in which that process was running.

Explanation:
A kernel panic is a type of error that occurs when the core (kernel) of an operating system receives an instruction in an unexpected format or when it fails to handle properly. A kernel panic can also follow when the operating system can't recover from a different type of error. A kernel panic can be caused by damaged or incompatible software or, more rarely, damaged or incompatible hardware.
When a server kernel panics it abruptly halts all normal system operations. Usually, a kernel process named panic() outputs an error message to the console and stores debugging information in nonvolitile memory to be written to a crash log file upon restarting the computer. Saving the memory contents of the core and associated debugging information is called a "core dump."

If you are assigning a static IP address,use the following syntax:
# ipadm create-addr -T static -a address addrobj where addrobj uses the naming format interface/user-defined-string,such as e1000g0/v4globalz.
Note: create-addr [-t] -T static [-d] -a {local | remote}=addr[/prefixlen],... addrobj Creates a static IPv4 or IPv6 address on the interface specified in addrobj. If the interface on which the address is created is not plumbed,this subcommand will implicitly plumb the interface. The created static address will be identified by addrobj. By default,a configured address will be marked up,so that it can be used as a source or destination of or for outbound and inbound packets.

Explanation:
The sulog file, /var/adm/sulog, is a log containing all attempts (whether successful or not) of the su command. An entry is added to the sulog file every time the su command is executed. The fields in sulog are: date, time, successful (+) or unsuccessful (-), port, user executing the su command, and user being switched to. In the preceding example, all su attempts were successful, except for the attempt on 2/23 at
20:51, when user pete unsuccessfully attempted to su to user root.
Look for entries where an unauthorized user has used the command inappropriately. The following entry shows a successful (indicated by +) su from user userid to root.
SU 03/31 12:52 + pts/0 <userid>-root
