| Certification Summary The node name of a machine can be found in a file /etc/<nodeName> on
the machine, and the host name associated with an interface (specified by
<interface>) of the machine can be found in the
/etc/hostname.<interface> file.
Each entry in the /etc/hosts contains the following information about a host:
host name, IP address associated with it, and nickname (alias), if any.
When you enable or disable a network service on your Solaris system by using,
say, the svcadm command, the service status change is recorded in the service
configuration repository and will persist across reboots.
Look Out
Because a hardware address is burned into the Ethernet NIC, if you change the
Ethernet card, the hardware address of your computer changes.
Because every IP address has a network component in it, if you move your
machine from one network to another, its IP address will change.
The inetadm command is used to manage inetd-controlled services, whereas
svcadm is the SMF command to manage the network services.
Memorize
The netsat utility is used to view the network packets' activity (statistics)
on inbound/outbound connections of your machine.
The ping command is used to check the reachability of another host on the
network (or the Internet).
The snoop command is used to look into the incoming/outgoing packets on your
machine (e.g., the values for the header fields).
The ifconfig command is used to configure a network interface such as assign
an IP address to it, bring it up, or shut it down. You can also use this command
to obtain configuration information about an interface. |
