Configuration 1: Startup Files for a Host in a Basic
NonStop TCP/IP Environment
Type Syntax Description
Line
ADD DEFINE 
=TCPIP^HOST^FILE, 
FILE 
$SYSTEM.ZTCPIP.HOST
S
Sets the =TCPIP^HOST^FILE define to 
point to the desired HOSTS file. When set, 
this define tells the DNR to use the 
HOSTS file to translate host names to IP 
addresses. For information about the 
RESOLVER, see RESCONF Details
 on 
page 3-37 and the TCP/IP Programming 
Manual.
Run Command
TCPIP/NAME $ZTC0, 
NOWAIT, CPU 1/0
Starts the TCP/IP process named $ZTC0 
in processors 1 (primary) and 0 (backup).
Run Command
TCPIP/NAME $ZTC1, 
NOWAIT, CPU 1/0
Starts the TCP/IP process named $ZTC1 
in processors 1 (primary) and 0 (backup). 
Note that TCP/IP starts at a priority of 200, 
regardless of the priority specified in the 
RUN command.
Line
ADD DEFINE 
=TCPIP^PROCESS^NAME
, FILE $ZTC1
Sets the =TCPIP^PROCESS^NAME 
parameter to $ZTC1. If you set the 
=TCPIP^PROCESS^NAME parameter, 
you must do so before starting the 
LISTNER and TELSERV processes. By 
doing so, you allow a newly started 
LISTNER or TELSERV process to 
examine the parameter specification and 
know which TCP/IP process to use. 
$ZTC0 is the recommended first name to 
use for the NonStop TCP/IP process. 
$ZTC0 is also the default value for 
applications on a NonStop system. Note 
that no ADD DEFINE statement exists for 
$ZTC0 because the LISTNER and 
TELSERV processes use it automatically 
if there is no TCP/IP process name 
defined. Successive NonStop TCP/IP 
process names should be $ZTC1, $ZTC2, 
and so on.
Run Command
LISTNER/NAME 
$LSN1,CPU 4, 
NOWAIT, IN $ZHOME, 
&
OUT $ZHOME, TERM 
$ZHOME,PRI 160/3 
$SYSTEM.TCPIP.PORTC
ONF
Starts the LISTNER process responsible 
for starting the ECHO, FINGER, and FTP 
servers when a client request is received 
by the LISTNER process. Consequently, 
you should run this process at a higher 
priority. This command also specifies the 
location of the PORTCONF file used to 
designate which ports this process is to 
listen to. This process requires privileged 
access to some NonStop TCP/IP ports: 
therefore, always start with a super group 
ID.
