  NAME

    server.dat - XNS server information file

  DESCRIPTION

    The /usr/ip32/inc/server.dat file contains information about Xerox Network
    System (XNS) servers on the local machine.  The server.dat file allows
    client and server programs to be linked together.  The sernum and server
    arguments to the sni_connect() function are used to access the proper
    server entry in server.dat.

    Every server started by the xns_listener command has one entry in
    server.dat.  Each entry in server.dat has four fields.  Each field is
    delimited by an exclamation point (!), with the first and the last
    character of the entry also containing an exclamation point.  Each entry
    contains the following information:

    ⊕  server number

    ⊕  flags

    ⊕  server path and arguments

    ⊕  default login name

    The server number is a value from 0-32767, inclusive, which corresponds to
    sernum.   The flags allow the xns_listener to control access to a server.
    The following flags are supported:

    U   Require username.

    P   Require password.

    D   Use default username.

    N   Disallow null passwords.

    If a username or a password is required, the xns_listener will not start
    the server unless sni_connect() gives a proper username and/or password.
    If the flags specify a default username, the default login name is used.
    If sni_connect() specifies a sernum of 0, the server argument is used as
    the path to the server.  Otherwise, the server path in the server.dat file
    is used.

  EXAMPLES

    The following is an example of a server.dat file:

    !0!UP!!!
    !6!UP!/usr/ip32/inc/fmus!!

  FILES

    /usr/ip32/inc/server.dat   Server list.

  NOTES

    Server number 0 can be useful for debugging.

    The xns_listener reads server.dat every time a server is started.  It does
    not need to be restarted to know about new server entries.

  CAUTIONS

    Intergraph reserves server numbers 0-999.
