TCP/IP Configuration Files
TCP/IP Configuration Files
There are several files that come on your system update tape (SUT) that are used for
configuring your Internet environment. You need to customize some of these files to
match your own environment.
The services files (customize the first four files here for your environment):

HOSTS File

IPNODES File

RESCONF File

NETWORKS File

PROTOCOL File

SERVICES File

PORTCONF File
The names of all these files begin with $SYSTEM.ZTCPIP, unless they are installed on
another subvolume.
These files are standard EDIT type files (file code 101); you can use a text editor such
as EDIT or PS Text Edit (TEDIT) to modify them. Each of these files consists of a
sequence of one-line entries. Lines starting with a pound sign (#) in the Internet
environment are comment lines.
HOSTS File
NonStop TCP/IPv6 hosts communicate through their IP addresses. However, IP
addresses are not easy to remember. As a result, it is common practice to assign host
names to IP addresses. Hosts then can be referred to by name. To provide for the
translation, a Domain Name Resolver (DNR) is provided. A DNR, in turn, uses either a
Domain Name Server (DNS) or a HOSTS file; configure the DNR to use one or the
other. (For more information about the DNR and DNS, see Appendix E, Domain Name
Server (DNS)).
The HOSTS file is a simple edit type file that contains an entry for each remote host
known to your system. Specify each remote host's IP address, host name, and alias.
Each entry in the HOSTS file has this format:
IP_address host_name [alias...]
The IP_address is a 32-bit numeric value expressed in dotted decimal form. The
IP_address must begin in the first column of an entry in your edit file. The host_name
and aliases are alphanumeric and separated by at least one space.
