DKHOSTS(4) DKHOSTS(4)

E-75 CommKit Host Interface, Release 4.0

NAME

dkhosts – host control file

DESCRIPTION

dkhosts is used by the maphost(3X) function to construct the appropriate AT&T data switch dialstring for

the host referenced. The file consists of one or more lines, each with exactly four fields. Each time

maphost(3X) is called, it scans dkhosts for the first match with the Host and the service Classes specified.

If a match is found, the remaining fields indicate the appropriate data switch dialstring for that particular host

and include miscellaneous information to be parsed. The fields that participate in the match are the Host and

Classes fields.

The lines consist of the following fields delimited by tabs.

Note: Delimit fields by tabs only. Do not use blanks.

Host: Host to which the call is being made.

Classes: Service class to match:

d dkdo

f file transfer

l remote login

p printer

x remote execution

Dialstring: Dialstring of host.

Miscellany: Subfields in this field are separated by commas and have two-character names constructed

from the service class character and another character appropriate to the service class. The

characters representing the field names are:

c command to execute

s service name

v existence of environment variables (y or n)

p protocol string

o old protocol (y or n)

EXAMPLES

An entry of ls=rx in the Miscellany field in the dkhosts file, would mean that for remote login the service

invoked is ’rx’.

An entry of fo=y in the Miscellany field in the dkhosts file, would mean that for file transfer the old file

transfer protocol is to be used.
