Dedicated ports are configured in the dedicated port file,
/etc/ddfa/dp.
The dp file is an ASCII file which consists
of entries, one for each dedicated port, using one of the formats
below.
For outgoing connections (ports for output devices such
as printers and plotters):
<DTC IP Addr> <board>/<port> <pseudonym> <pcf> <DTC Nodename> <board>/<port> <pseudonym> <pcf> <Server IP Addr> XX/XX <pseudonym> <pcf> <Server Name> XX/XX <pseudonym> <pcf> <Server IP Addr> XX/<port TCP addr> <pseudonym> <pcf>
|
For incoming connections (ports for input devices such
as terminals):
<DTC IP Addr> <board>/<port> <pseudonym> <DTC Nodename> <board>/<port> <pseudonym>
|
The fields are defined as:
- DTC IP Addr
The IP address assigned to the DTC, or to one of
its ports. The IP address is configured on the server and its ports
by using the DTC Manager.
- DTC Node Name
The Node Name assigned to the DTC or one of its
ports. The Node Name is configured on the server and its ports by
using the DTC Manager.
- board
The physical DTC board of the port to be dedicated. Refer to
the DTC hardware documentation for number of boards per each DTC
type.
If XX/XX
is specified for <board>/<port>,
then the specified IP address or nodename references a port on the
server and not the server itself.
- /
A slash must separate the board and port numbers.
- port
The port number of the DTC port
to be dedicated. Refer to the DTC hardware documentation for number
of ports per board for each DTC type.
- port TCP addr
The port TCP address of the server port
to be dedicated. Refer to the server manufacturer's documentation
for the type of addressing format used.
- pseudonym
The name of a pseudonym
that will be used to access the dedicated server port.
The device file name can be from 1 to 14 characters. The name of
this file is created by the system administrator, and must not be
the name of a file which already exists, or is already in use by
the system. This file is created and managed solely by the DDFA
Utilities
and/or the Telnet daemon.
HP recommends using a name which helps identify the DTC port
being referenced, such as /dev/telnet/dtc1b2p4
for DTC1, board 2, port 4.
- pcf
Used for outgoing connections only. The /etc/ddfa/pcf
file contains the port configuration which is used for the Telnet
connection
to the DTC or non-DTC port.
Refer to Chapter 5 for examples of how dedicated port (dp)
files are used by DDFA.
