Installation guide

You use the netsetup command to add your system to a local area
network (LAN).
This command is the same as the ULTRIX netsetup command, except
that on a DIGITAL UNIX system, the netsetup command has
additional features and a different interface.
• netstat
The netstat command displays network statistics, such as interface
counters, protocol counters, and routing information.
• netx
This command is unavailable on DIGITAL UNIX systems. The
DIGITAL UNIX system does not supply network exerciser software.
• ping
The ping command sends Internet Control Message Protocol (ICMP)
ECHO_REQUEST packets to network hosts.
The ping command is the same on DIGITAL UNIX and ULTRIX
systems, except that on a DIGITAL UNIX system, the −l option causes
the command to send a specified number of packets. On an ULTRIX
system, this option causes the ping command to display long output.
The DIGITAL UNIX ping command displays long output by default
(verbose mode is on).
You can use the ping command on a DIGITAL UNIX system to get
information about an ULTRIX system; also, you can enter the command
on an ULTRIX system to get information about a DIGITAL UNIX
system.
• .rhosts and /etc/hosts.equiv
The DIGITAL UNIX system does not support −host, +@group,or
−@group syntax.
• rdate
The rdate command sets the current system date and time to the
network date and time.
The rdate command is the same on DIGITAL UNIX and ULTRIX
systems. (You can also use the Network Time Protocol (NTP) and Time
Synchronization Protocol (TSP) to synchronize your system time. For
information about NTP and TSP, see Section 4.15.3.)
• screend
The screend daemon is the same on DIGITAL UNIX and ULTRIX
systems. This daemon instructs the kernel to accept or reject IP packets
during forwarding, depending on how it is configured.
• screenmode
