slp.reg(4) Kernel Interfaces Manual slp.reg(4)
NAME
slp.reg - SLP static registration file
SYNOPSIS
DESCRIPTION
The file provides a mechanism for old applications which are not SLP enabled and cannot be converted, and for portably exchanging registra-
tions between SLP implementations.
This file contains a list of service registrations that are read by slpd at startup time and advertised later by slpd which can be acting
either as the service agent server or the directory agent.
The character encoding of the registrations is required to be UTF-8.
The syntax of the serialized registration file, in ABNF format [5], 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 scope names, attribute tags, and attribute values requires escapes for special characters. DAs and SA servers that process
serialized registrations must handle them 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 signaled and the type name is ignored. If the maximum lifetime is
specified (65535 sec.), the registration is taken to be permanent, and is continually refreshed by the DA or SA server until it exits.
Scopes can be included in a registration by including an attribute definition 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 registrations 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 the scope list contains scopes that are not in the net.slp.useScopes property (provided that property is set) or are not specified by
DHCP, the API library should reject the registration and issue a warning message.
