IBM_HOSTS(5)IBM_HOSTS(5)NAMEibm_hosts - host database for x3270
SYNOPSIS
/usr/lib/X11/x3270/ibm_hosts
DESCRIPTION
The ibm_hosts file contains information regarding IBM
hosts on the network. An IBM host is a host which can
communicate with a 3270 terminal emulator such as x3270 or
tn3270. Each line defines a name in the following format
(optional fields are shown in brackets):
name type hostname[/port] [actions]
Items are separated by any number of blanks and/or TAB
characters. A line beginning with `#' is taken as a com-
ment (note that `#' anywhere else on a line does not indi-
cate a comment).
The name field is a mnemonic used to identify the host.
The type field is a keyword that indicates the type of
entry. The value primary means that the name will be
included in host-selection menus that may be displayed by
a 3270 emulator. The value alias means that the name will
not be included in menus, but will still be accepted as
valid input when a host name is required.
The hostname field is the Internet hostname or dot-nota-
tion Internet address of the host.
The hostname can also optionally include a non-default
port number, appended to the hostname with a slash ``/''
character, e.g., bluehost/97.
The optional actions field specifies actions to be taken
once the connection is made and a data-entry field is
defined. If the text looks like an action, e.g., PF(1),
it is unmodified; otherwise it is taken as the parameter
to the String() action. The actions are not intended for
entering usernames and passwords; rather they provide an
automated way of specifying a front-end menu option.
EXAMPLE
Given the following ibm_hosts file:
mvs primary mvs-host
tso alias mvs-host
mvs2 primary mvs-host/4012
vm primary vtam Tab()String(3)Enter()
An 3270 emulator will display four names (mvs, mvs2,
afhost and vm) on its hosts menu. The names mvs and tso

will cause connections to the host mvs-host. The name
mvs2 will also cause a connection to mvs-host, but to port
4012 rather than the emulator's default port (usually 23).
The name vm will cause the 3270 emulator to connect to the
host vtam (presumably some sort of host-selection front-
end), enter the string ``3'' on the second data-entry
field on the screen, and send the ENTER AID sequence.
