Startup Files for GTWY1
All text following a pound sign (#) is comment text. Use comment text to note revisions
made to the file, the name of the IOP, the hardware address of the ServerNet adapter,
and so on. Knowing the hardware address of the ServerNet adapter helps you when
you test the network through the HP Tandem Services Manager (TSM).
Begin the IP addresses of the hosts in column one of the HOSTS file. Separate the
host name from the address by at least one space. You may have as many aliases as
can fit on a single entry line.
The lines in the HOSTS file:
127.0.0.1 me loop
150.50.130.2 LAN01 lan01 doc1
150.50.130.3 LAN02 lan02 doc2
provide flexibility in testing the environment. When you use the ECHO service to send
an echo datagram to
me or loop, you are testing the client and server capabilities of
your own ECHO service. If you send an ECHO datagram to lan01 or lan02, you also
are testing the actual physical network connection for your HOST1 NonStop TCP/IP
environment.
The sample configuration assumes that all the hosts and gateways on this small
internet are NonStop hosts. This HOSTS file easily accommodates the IP addresses
and names of any host connected to the TCP/IP network.
Startup Files for GTWY1
GTWY1 is a NonStop system that has two E4SA adapters. The configuration for
GYWY1 is shown in Figure F-6
. Each E4SA adapter is attached to a different network;
each has a separate IP address. Since this NonStop system is being configured as a
gateway, a single NonStop TCP/IP process interfaces with both I/O processes. If you
configure each E4SA adapter with a separate NonStop TCP/IP process, the system
could not act as a TCP/IP gateway. Since most of the startup files are very similar to
those of HOST1 in Startup Files for HOST1
on page F-5, only the differences between
