• Oracle Solaris 11.3 Network Documentation
• Oracle Basic Network Configuration Scenario

Brief Overview

• Oracle introduced dladm and ipadm to supersede ifconfig
• Changes made by dladm and ipadm persist across reboots.
• Also added automatic network configuration using network profiles.
• netadm and netcfg describe configuration of network related policies.
• Automatic NCP: uses DHCP to obtain basic network configuration

• DefaultFixed NCP: disables automatic network configuration and requires the network interfaces to be manually configured using dladm and ipadm.

• dladm: Data-link (layer 2) administration - links, VLANs, IP tunnels.

• data-link names are given generic names and are no longer the same as physical interface.

• ipadm: Configures IP interfaces, IP addresses and TCP/IP properties.

Basic Commands

ifconfig -a
ifconfig net0
ifconfig net0 up
ifconfig net0 down

ping 192.168.x.x
ping -s 192.168.x.x

ping gateway_addr to check that network is working
traceroute url

netcfg

ifconfig
ifconfig -a

ipadm         # Lists network cards, their class, state and address
netadm        # Enters interactive mode
netadm list   # Lists

netadm enable -p ncp Automatic          # Will enable DHCP
ipadm show-if                           # Display status of interface
ipadm show-addr                         # Display IP addresses of interfaces

netstat                                 # Shows network status, state of sockets, routing etc.
who                                     # Shows which users are connected to your network.                    

Configuring a DHCP Server

• Working with DHCP in Oracle
• Needs root access, or an appropriate role like "DHCP Management":

usermod -P+"DHCP Management" username

• By default the DHCP server and relay is disabled

svcs -a|grep dhcp       # Can be used to locate the DHCP service
svcs relay           

• How to Configure an ISC DHCP Server

Configure a Static IP Address

netadm enable -p ncp DefaultFixed       # Will disable DHCP, allow manual config
dladm show-phys                         # Will display network devices
                                        # Status changed from up -> unknown
ipadm create-ip net0
ipadm show-if

# Add a persistent default route:
route -p add default 10.163.198.1       # Adds a default gateway
route -p show                           # Shows persistent route

Name Service Configuration using SMF

• Use svc:/network/dns/client
• https://docs.oracle.com/cd/E36784_01/html/E36831/dnsref-36.html

svccfg -s system/name-service/switch
svc:/system/name-service/switch> setprop config/host = astring: "files dns"
svc:/system/name-service/switch:default> refresh
svc:/system/name-service/switch:default> quit
