Creating the Device File Name with the DDFA Utility

The location of the printer (port number on the DTC) and an assigned device ﬁle

name must be speciﬁed in a DDFA utilities conﬁguration ﬁle. This chapter describes

how to use DDFA to conﬁgure a printer on a DTC for access by HP 9000 systems.

Refer to the DTC Device File Access Utilities Manual and HP-UX System

Administration Tasks Manual from your HP-UX System Administrator's

documentation set for more information about DDFA. More information is also

available in these man pages:

• ddfa(7) DTC Device File Access Utilities description

• dp(4) Dedicated port file

• dpp(1m) Dedicated port file parser

• ocd(1m) Outbound connection daemon

• ocdebug(1m) Debug version of ocd

• pcf(4) Port configuration file

Creating the Device File Name with the DDFA Utility

DDFA conﬁguration is dependant on the newconfig/ddfa/dp ﬁle. Follow the

procedure below to create a device ﬁle name for the printer port.

1 Ensure that you are logged in as root.

2 Check whether the file ddfa/dp exists.

If this ﬁle already exists, go to step 6

If this ﬁle does not exist, go to step 3

3 Create a directory for the DDFA files, as follows ( HP recommends

ddfa):

mkdir ddfa

4 Copy the master template dedicated port file, dp, to the DDFA directory:

cp newconfig/ddfa/dp ddfa/dp

Do not alter newconfig/ddfa/dp, so that you keep a master template dp ﬁle.

5 Copy the master template port configuration file, pcf, to the DDFA directory:

cp newconfig/ddfa/pcf ddfa/pcf

Do not alter newconfig/ddfa/pcf, so that you keep a master template pcf

ﬁle.

6 For each DTC printer that you wish to permanently associate with a particular

device file, perform the following steps:

a Find the IP Address of the DTC, and the port number on the DTC to which
