superdaemon ( /etc/inetd.conf and /etc/services ) to initiate the multinoded.
The sections may be either a simple section or a valued section. A simple substanza is a single
name/Dot Notation IP Address to be used for both “Control” connection and “Data” connection. The
valued substanza is used to specify the name/Dot Notation IP Address for the “Control” connection
(specifier) and the name/Dot Notation IP Address for the “Data” connection (value.)
Multinode Table Stanza Rules:
•
SubStanza hostnames (local hosts) may contain one or more hostnames separated by white
spaces (subject to the HPSS.conf line character limit.)
•
Section hostnames (remote hosts) [and/or values] may be specified as either string-based
hostnames or Dot Notation IP Addresses. Only one entry per line.
Multinode Table Example:
# Options read by the Multinode Daemon
Multinode Table = {
# Diagnostic Delay
; Sleep for Debugger = 15
# Hostname of the Client
water water.clearlake.ibm.com =
# Name of the system running the PFTP Server
pftp_server pftp_server.clearlake.ibm.com = {
# Specification of the Multinode Host
# If the Data Node is a different interface than the interface
# specified by the Control Node; then enter the Data Node
# Interface after the "=" otherwise the Control and Data
# are the same.
# Control and/or Data may be dot notation OR string hostnames.
Water = 134.253.14.227
}
}
Default = {
Default = {
# If the Data Node is different than the Control Node
# Enter the Data Node after the "=" otherwise the
# Control and Data are the same.
# Control and/or Data may be dot notation OR string hostnames.

D.4. Network Option Stanza
The Network Options are in the Network Options = { … } stanza of the HPSS.conf file.
The Network Options stanza allows different options to be specified based on: Source IP address
[ Local Interface Name(s) ] AND Destination IP Address(es). When the Parallel FTP Client, Client
API, or Mover establish connections, they will search the contents of this file for entries matching
Source/Destination IP addresses and use the options specified in the matching entry.
The configuration file entries contain values/flags to be used for applying assorted socket and
network options including: whether to enable/disable TCP Delay
(TcpNoDelay), the socket send
sizes (SendSpace) and/or socket receive sizes (RecvSpace) , the desired write buffer size
(WriteSize) , and RFC1323 support (“Large” Window.)
Which configuration entry to use is determined based on the Local Interface Name and the
