NAME

       ibm_hosts - host database for x3270 and c3270

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  c3270.
       Each line defines a name in the following format (optional fields are shown in brackets):

       name type [opt:]...[luname@]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 # anywhere else on a line does not indicate 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-notation Internet address of the host.

       The  hostname  can  include  `s:'  or  `p:' prefixes, e.g., s:finicky (see the x3270(1) or
       c3270(1) man page sfor details).  It can also include an LU  name,  separated  by  an  `@'
       character,  e.g.,  oddlu@bluehost.   Finally,  it  can  include a non-default port number,
       appended  to  the  hostname  with  a  colon  `:'  character,  e.g.,   bluehost:97.    (For
       compatibility  with  earlier  versions of x3270, the port can also be separated by a slash
       `/' character.)

       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()

       A 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.
