RFC 931                                                     January 1985
Authentication Server


QUERY/RESPONSE FORMAT

   The server accepts simple text query requests of the form

      , 

   where  is the TCP port (decimal) on the target (server)
   system, and  is the TCP port (decimal) on the source
   (user) system.

      For example:

         23, 6191

   The response is of the form

      ,  :  : 

   where , are the same pair as the query,
    is a keyword identifying the type of response, and
    is context dependent.

      For example:

         23, 6191 : USERID : MULTICS : StJohns.DODCSC.a
         23, 6193 : USERID : TAC : MCSJ-MITMUL
         23, 6195 : ERROR : NO-USER

RESPONSE TYPES

   A response can be one of two types:

   USERID

      In this case,  is a string consisting of an
      operating system name, followed by a ":", followed by user
      identification string in a format peculiar to the operating system
      indicated.  Permitted operating system names are specified in
      RFC-923, "Assigned Numbers" or its successors.  The only other
      names permitted are "TAC" to specify a BBN Terminal Access
      Controller, and "OTHER" to specify any other operating system not
      yet registered with the NIC.
