slpd.reg(4)                      File Formats                      slpd.reg(4)

       slpd.reg - serialized registration file for the service location proto-
       col daemon (slpd)


       The serialized registration file contains a group of registrations that
       slpd(1M)  registers  when  it starts. These registrations are primarily
       for older service programs that do not internally support SLP and  can-
       not  be  converted.  The  character  format of the registration file is
       required  to  be  ASCII.  To  use  serialized  registrations,  set  the
       net.slp.serializedRegURL  property   in slp.conf(4) to point at a valid
       slpd.reg file. The syntax of the serialized registration file, in  ABNF
       format (see RFC 2234), is as follows:

       ser-file      =  reg-list
       reg-list      =  reg / reg reg-list
       reg           =  creg / ser-reg
       creg          =  comment-line ser-reg
       comment-line  =  ( "#" / ";" ) 1*allchar newline
       ser-reg       =  url-props [slist] [attr-list] newline
       url-props     =  surl "," lang "," ltime [ "," type ] newline
       surl          =  ;The registration's URL. See
                        ; [8] for syntax.
       lang          =  1*8ALPHA [ "-" 1*8ALPHA ]
                        ;RFC 1766 Language Tag see [6].
       ltime         =  1*5DIGIT
                        ; A positive 16-bit integer
                        ; giving the lifetime
                        ; of the registration.
       type          =  ; The service type name, see [7]
                        ; and [8] for syntax.
       slist         =  "scopes" "=" scope-list newline
       scope-list    =  scope-name / scope-name "," scope-list
       scope         =  ; See grammar of [7] for
                        ; scope-name syntax.
       attr-list     =  attr-def / attr-def attr-list
       attr-def      =  ( attr / keyword ) newline
       keyword       =  attr-id
       attr          =  attr-id "=" attr-val-list
       attr-id       =  ;Attribute id, see [7] for syntax.
       attr-val-list =  attr-val / attr-val "," attr-val-list
       attr-val      =  ;Attribute value, see [7] for syntax
       allchar       =  char / WSP
       char          =  DIGIT / ALPHA / other
       other         =  %x21-%x2f / %x3a-%x40 /
                        %x5b-%x60 / %7b-%7e
                         ; All printable, nonwhitespace US-ASCII
                         ; characters.
       newline       =  CR / ( CRLF )

       The  syntax for attributes and attribute values requires that you use a
       backslash to escape special characters, in addition to non-ASCII  char-
       acters,  as  specified in RFC 2608. The slpd command handles serialized
       registrations exactly as if they were registered by an SA. In the  url-
       props  production,  the  type  token  is optional. If the type token is
       present for a service: URL, a warning is signalled, and the  type  name
       is  ignored. If the maximum lifetime of 65535 seconds is specified, the
       registration is taken to be permanent, and it is continually  refreshed
       by the DA or SA server until it exits.

       Scopes can be included in a registration by including an attribute def-
       inition with tag scopes followed by a  comma-separated  list  of  scope
       names  immediately  after  the  url-props  production.  If the optional
       scope-list is present, the  registations  are  made  in  the  indicated
       scopes;  otherwise, they are registered in the scopes with which the DA
       or SA server was configured through the net.slp.useScopes property.  If
       any  conflicts  occur  between the scope list and the net.slp.useScopes
       property, an error message is issued by way  of  syslog(3C).  Refer  to
       information regarding LOG_INFO in syslog(3C).

       Service  advertisements are separated by a single blank line. Addition-
       ally, the file must end with a single blank line.

       Example 1: Using a Serialized Registration File

       The following serialized registration file shows  an  instance  of  the
       service  type  foo, with a lifetime of 65535 seconds, in the en locale,
       with scope somescope:

       # register foo

       # next registration...
