The following listing shows the output of the
netstat -i
command, which
is used to list the status and statistics for the physical interfaces:

Column
Description
Name
The interface name.
Mtu
The maximum transmission unit (maximum packet size).
Net/Dest
The local network. (If possible, the network is mapped to a network
name using the
/etc/networks
file or the appropriate name service.)
Address
The IP address of the interface. (If possible, the address is mapped to a
hostname using the
/etc/hosts
file or the appropriate name service.)
Ipkts
The number of input packets.
Ierrs
The number of input errors.
Opkts
The number of output packets.
Oerrs
The number of output errors.
Collis
The number of network collisions.
Queue
The number of packets waiting in the queue.
Note that both the
ifconfig
and the

Ethernet address associated with a network interface.
Open Network Computing (ONC) and the
Remote Procedure Call (RPC) Mechanism
Sun Microsystems has developed an environment for supporting distributed
computing services. This environment is referred to as Sun's Open Network
Computing Plus (ONC+) Technologies. The ONC+ Technologies is a fam-
ily of technologies, services, and tools. The main components are
Applications
—NFS and NIS+ services. They use Remote Procedure
Calls to accomplish the client-server interaction.
