slp.conf \- configuration file for Service Location Protocol agents
.SH SYNOPSIS
.LP
.nf
\fB/etc/inet/slp.conf\fR
.fi

.SH DESCRIPTION
.sp
.LP
\fBslp.conf \fR provides all  Service Location Protocol ("\fBSLP\fR") agents
with  their  operational  configuration. \fBslpd\fR(8) reads \fBslp.conf\fR on
startup. Service Agents ("\fBSA\fRs") and User Agents ("\fBUA\fRs") read
\fBslp.conf\fR on invocation of the \fBSA\fR and \fBUA\fR  library routines;
configuration parameters are then cached on a per-process basis. All \fBSA\fR's
must use the same set of properties as \fBslpd\fR on the local machine, since
\fBslpd\fR acts as an \fBSA\fR server.
.sp
.LP
The configuration file format consists of a newline-delimited list of zero or
more property definitions. Each property definition corresponds to a particular
configurable \fBSLP\fR, network, or other parameter in one or more of the three
\fBSLP\fR agents. The file format grammar is shown in \fIRFC 2234\fR as
follows:
.sp

line-list     =  line / line line-list
line          =  property-line / comment-line
comment-line  =  ( "#" / ";" ) 1*allchar newline
property-line =  property newline
property      =  tag "=" value-list
tag           =  prop / prop "." tag
prop          =  1*tagchar
value-list    =  value / value "," value-list
value         =  int / bool /
                 "(" value-list ")" / string
int           =  1*DIGIT
bool          =  "true" / "false" / "TRUE" / "FALSE"
newline       =  CR / ( CRLF )
string        =  1*stringchar
tagchar       =  DIGIT / ALPHA / tother / escape

                 %x5b-%x60 / %7b-%7e
                 ; i.e., all characters except `,'
allchar       =  DIGIT / ALPHA / HTAB / SP

A comma-separated list of parenthesized attribute tag/value list pairs that the
\fBDA\fR must advertise in \fBDA\fR advertisements.  The property must be in
the \fBSLP\fR attribute list wire format, which requires that you use a
backslash ("\\") to escape reserved characters. See \fIRFC 2608\fR for more

List of Strings
.RE

A list of  strings indicating either the scopes that a  \fBUA\fR or an \fBSA\fR
is allowed to use when making requests, or the scopes  a \fBDA\fR  must
support. If not present for the \fBDA\fR and \fBSA\fR, the default scope
\fBDefault\fR is used. If not present for the \fBUA\fR, then the user scoping
model is in force, in which active and passive \fBDA\fR or \fBSA\fR discovery
are used for scope discovery. The scope \fBDefault\fR  is used if no other
information is available. If a \fBDA\fR or \fBSA\fR gets another  scope in a
request, a \fBSCOPE_NOT_SUPPORTED\fR error is  returned, unless the request was
multicast, in which case it is dropped. If a \fBDA\fR receives another scope in
a registration, a \fBSCOPE_NOT_SUPPORTED\fR error will be returned.  Unlike
other properties, this property is "read-only", so  attempts to change it
programmatically after the configuration file has been  read are ignored.

IPv4 addresses or host names
.RE

A  list of  \fBIP\fR  addresses  or  \fBDNS\fR-resolvable  names that denote
the  \fBDA\fRs to  use for statically  configured \fBUA\fRs and  \fBSA\fRs. The
property is read by \fBslpd\fR(8), and registrations are forwarded to the
\fBDA\fRs. The \fBDA\fRs are provided to \fBUA\fRs upon request. Unlike other
properties, this property is "read-only", so attempts to change it after the
configuration file has been read are ignored.
.sp
The following grammar describes the property:
.sp
.in +2
.nf
addr-list  =  addr / addr "," addr-list
addr       =  fqdn / hostnumber
fqdn       =  ALPHA / ALPHA *[ anum / "-" ] anum
anum       =  ALPHA / DIGIT
hostnumber =  1*3DIGIT 3("." 1*3DIGIT)
.fi
.in -2

The following is an example using this grammar:
.sp
.in +2
.nf
sawah,mandi,sambal
.fi
.in -2

\fBIP\fR addresses can be used instead of host names in networks where
\fBDNS\fR is not deployed, but network administrators are reminded that using
\fBIP\fR addresses will complicate machine renumbering, since the \fBSLP\fR
configuration property files in statically configured networks will have to be
changed.

Service type names
.RE

A list of service type names.  In the absence of any \fBDA\fRs, \fBUA\fRs
perform \fBSA\fR discovery to find scopes.  If the \fBnet.slp.typeHint\fR
property is set, only \fBSA\fR's advertising types on the list respond. Note
that \fBUA\fRs set this property programmatically. It is not typically set in
the configuration file. The default is unassigned, meaning do not restrict the
type.
