RPC programming. On HP-UX 10.30 and later,
Transport-Independent RPC (TI-RPC) is supported. For information
on RPC and rpcgen, see Power Programming with RPC, by John
Bloomer, published by O’Reilly and Associates, Inc.
• Remote Execution Facility (REX) allows you to execute
commands interactively on a remote host while your local
environment is simulated on the remote host. To use REX, you issue
the on command on your local host, supplying the command you
want to execute remotely and the name of the remote host where you
want the command to execute. Your current environment variables
are then copied to the remote host, and your home directory is
mounted on the remote host using NFS. For information on
configuring, administering, and using REX, see Chapter 7,
“Configuring and Using the Remote Execution Facility (REX).”
•The rup command collects and displays status information about the
hosts on the local network. All hosts running the rstatd daemon will
respond to queries from the rup command. For more information, see
the man pages rstatd(1M) and rup(1). For information on
configuring rstatd, see “Configuring the Other NFS Daemons and
Services” on page 132.
•The rusers command collects and displays information about all
users logged into the hosts on the local network. All hosts running
the rusersd daemon will respond to queries from the rusers
command. For more information, see the man pages rusersd(1M)
and rusers(1). For information on configuring rusersd, see
“Configuring the Other NFS Daemons and Services” on page 132.
•The rwall program allows you to broadcast a message to all the
users logged into a remote host. The rwall program sends a message
to a specified host where the rwalld daemon is running. The rwalld
daemon then writes the message to all the users logged into that
host. For more information, see the man pages rwalld(1M) and
rwall(1M). For information on configuring rwalld, see “Configuring
the Other NFS Daemons and Services” on page 132.
•The spray command sends a stream of packets to a specified host
and then reports how many of the packets were received and what
the transfer rate was. All hosts running the sprayd daemon will
respond to packets sent by the spray command. For more
information, see the man pages sprayd(1M) and spray(1M). For
information on configuring sprayd, see “Configuring the Other NFS
Daemons and Services” on page 132.
