SLPD.REG(5) File Formats and Configurations SLPD.REG(5)

NAME


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

SYNOPSIS


/etc/inet/slpd.reg


DESCRIPTION


The serialized registration file contains a group of registrations
that slpd(8) registers when it starts. These registrations are
primarily for older service programs that do not internally support
SLP and cannot 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(5) 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
characters, 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
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 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.
Additionally, the file must end with a single blank line.

EXAMPLES


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
service:foo://fooserver/foopath,en,65535
scopes=somescope
description=bogus
security=kerberos_v5
location=headquarters

# next registration...
