NAME

ibm_hosts -host database forx3270

SYNOPSIS

/usr/lib/X11/x3270/ibm_hosts

DESCRIPTION

Theibm_hostsfile contains information regarding IBM hosts on the network.AnIBM hostis a host which can communicate with a 3270 terminal emulator such asx3270ortn3270.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 comment (note that `#' anywhereelse on a line doesnotindicate a comment).

Thenamefield is a mnemonic used to identify the host.

Thetypefield is a keyword that indicates the type of entry.The valueprimarymeans that thenamewill be included in host-selection menus that may be displayed by a3270 emulator.The valuealiasmeans that thenamewill not be included in menus, but will still be accepted as valid inputwhen a host name is required.

Thehostnamefield is the Internet hostname or dot-notation Internet address of the host.

Thehostnamecan also optionally include a non-defaultportnumber, appended to thehostnamewitha slash ``/'' character,e.g.,bluehost/97.

The optionalactionsfield specifies actions to be taken once the connection is made and adata-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 theString()action.Theactionsare not intended for entering usernames and passwords; rather they provide anautomated way of specifying a front-end menu option.

EXAMPLE

Given the followingibm_hostsfile:

        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,afhostandvm)on its hosts menu.The namesmvsandtsowill cause connections to the hostmvs-host.The namemvs2will also cause a connection tomvs-host,but to port 4012 rather than the emulator's default port (usually 23).The namevmwill cause the 3270 emulator to connect to the hostvtam(presumably some sort of host-selection front-end),enter the string ``3'' on the second data-entry field on the screen, andsend the ENTER AID sequence.
