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.

IP address and name service (such as a DNS server) are provided by the DHCP server.

UFS quotas enable system administrators to control the size of file systems. Quotas limit the amount of disk space and the number of inodes, which roughly corresponds to the number of files, that individual users can acquire. For this reason, quotas are especially useful on the file systems where user home directories reside. As a rule, the public and /tmp file systems usually do not benefit significantly by establishing quotas.

Note: The cp command copies files and directories.

FLAGS

Indicates the status of each underlying interface, which can be one or any combination of the following:

(D) d indicates that the interface is down and therefore unusable.

(E) M indicates that the interface is designated by the system to send and receive IPv6 multicast traffic for the IPMP group.

Note:

i indicates that the INACTIVE flag is set for the interface. Therefore, the interface is not used to send or receive data traffic.

s indicates that the interface is configured to be a standby interface.

m indicates that the interface is designated by the system to send and receive IPv4 multicast traffic for the IPMP group.

b indicates that the interface is designated by the system to receive broadcast traffic for the IPMP group.

h indicates that the interface shares a duplicate physical hardware address with another interface and has been taken offline. The h flag indicates that the interface is unusable.

The dispadmin command displays or changes process scheduler parameters while the system is running.

-c class

Specifies the class whose parameters are to be displayed or changed. Valid class values are: RT for the real-time class, TS for the time-sharing class, IA for the inter-active class, FSS for the fair-share class, and FX for the fixed-priority class. The time-sharing and inter-active classes share the same scheduler, so changes to the scheduling parameters of one will change those of the other.

-g

Gets the parameters for the specified class and writes them to the standard output.

B: Setting the default route on Solaris is easy. If you are trying to just set the route temporarily you can use the route command:

Route add default

Example:

Route add default 192.168.1.1

Note: Route command manipulates the kernel routing tables. Routing is the process of forwarding a packet from one computer to another. It is based on the IP address in the IP packet header and netmask.

F: If you want the route to be persisted when you reboot the system, you will need to set the route in the /etc/defaultrouter file.

/etc/defaultrouter

Example:

Echo 192.168.1.1 > /etc/defaultrouter

'ipadm show-addr' displays all the configured addresses on the system.

Example:

# ipadm show-addr

ADDROBJ TYPE STATE ADDR

lo0/v4 static ok 127.0.0.1/8

lo0/v6 static ok ::1/128

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.

Single quotes are most strict. They prevent even variable expansion. Double quotes prevent wildcard expansion but allow variable expansion. For example:

#!/bin/sh

echo $SHELL

echo "$SHELL"

echo '$SHELL'

This will print:

/usr/bin/bash

/usr/bin/bash

$SHELL
